7. Depreciation, Depletion, and Amortization

What's New for 2007

Increased section 179 deduction dollar limits. The maximum amount you can elect to deduct for most section 179 property you placed in service in 2007 is $125,000. This limit is reduced by the amount by which the cost of the property placed in service during the tax year exceeds $500,000. See Dollar Limits under Section 179 Deduction, later.

What's New for 2008

Extension of increased section 179 deduction. If you own qualified section 179 GO Zone property acquired after August 27, 2005, and placed it in service before January 1, 2009, you may be eligible for an increased section 179 deduction.

Introduction

If you buy farm property such as machinery, equipment, livestock, or a structure with a useful life of more than a year, you generally cannot deduct its entire cost in one year. Instead, you must spread the cost over the time you use the property and deduct part of it each year. For most types of property, this is called depreciation.

This chapter gives information on depreciation methods that generally apply to property placed in service after 1986. For information on depreciating pre-1987 property, see Publication 534, Depreciating Property Placed in Service Before 1987.

To help you understand depreciation and how to complete Form 4562, Depreciation and Amortization, see the filled-in Form 4562 and related discussion in chapter 16.

It is important to keep good records for property you depreciate. Do not file these records with your return. Instead, you should keep them as part of the permanent records of the depreciated property. They will help you verify the accuracy of the depreciation of assets placed in service in the current and previous tax years. For general information on recordkeeping, see Publication 583, Starting a Business and Keeping Records. For specific information on keeping records for section 179 property and listed property, see
Publication 946.

Overview of Depreciation

This overview discusses basic information on the following.

What property can be depreciated.
What property cannot be depreciated.
When depreciation begins and ends.
Whether MACRS can be used to figure depreciation.
What is the basis of your depreciable property.
How to treat repairs and improvements.
When you must file Form 4562.
How you can correct depreciation claimed incorrectly.

What Property Can Be Depreciated?

You can depreciate most types of tangible property (except land), such as buildings, machinery, equipment, vehicles, certain livestock, and furniture. You can also depreciate certain intangible property, such as copyrights, patents, and computer software. To be depreciable, the property must meet all the following requirements.

It must be property you own.
It must be used in your business or income-producing activity.
It must have a determinable useful life.
It must have a useful life that extends substantially beyond the year you place it in service.

Property You Own

To claim depreciation, you usually must be the owner of the property. You are considered as owning property even if it is subject to a debt.

Leased property

You can depreciate leased property only if you retain the incidents of ownership in the property. This means you bear the burden of exhaustion of the capital investment in the property. Therefore, if you lease property from someone to use in your trade or business or for the production of income, you generally cannot depreciate its cost because you do not retain the incidents of ownership. You can, however, depreciate any capital improvements you make to the leased property. See Additions and Improvements under Which Recovery Period Applies in chapter 4 of Publication 946. If you lease property to someone, you generally can depreciate its cost even if the lessee (the person leasing from you) has agreed to preserve, replace, renew, and maintain the property. However, you cannot depreciate the cost of the property if the lease provides that the lessee is to maintain the property and return to you the same property or its equivalent in value at the expiration of the lease in as good condition and value as when leased.

Life tenant

Generally, if you hold business or investment property as a life tenant, you can depreciate it as if you were the absolute owner of the property. See Certain term interests in property, later for an exception.

Property Used in Your Business or Income-Producing Activity

To claim depreciation on property, you must use it in your business or income-producing activity. If you use property to produce income (investment use), the income must be taxable. You cannot depreciate property that you use solely for personal activities. However, if you use property for business or investment purposes and for personal purposes, you can deduct depreciation based only on the percentage of business or investment use.

Example 1

If you use your car for farm business, you can deduct depreciation based on its percentage of use in farming. If you also use it for investment purposes, you can depreciate it based on its percentage of investment use.

Example 2

If you use part of your home for business, you may be able to deduct depreciation on that part based on its business use. For more information, see Business Use of Your Home in chapter 4.

Inventory

You can never depreciate inventory because it is not held for use in your business. Inventory is any property you hold primarily for sale to customers in the ordinary course of your business.

Livestock

Livestock purchased for draft, breeding, or dairy purposes can be depreciated only if they are not kept in an inventory account. Livestock you raise usually has no depreciable basis because the costs of raising them are deducted and not added to their basis. However, see Immature livestock under When Does Depreciation Begin and End, later for a special rule.

Property Having a Determinable Useful Life

To be depreciable, your property must have a determinable useful life. This means it must be something that wears out, decays, gets used up, becomes obsolete, or loses its value from natural causes.

Irrigation systems and water wells

Irrigation systems and wells used in a trade or business can be depreciated if their useful life can be determined. You can depreciate irrigation systems and wells composed of masonry, concrete, tile, metal, or wood. In addition, you can depreciate costs for moving dirt to construct irrigation systems and water wells composed of these materials. However, land preparation costs for center pivot irrigation systems are not depreciable.

Dams, ponds, and terraces

In general, you cannot depreciate earthen dams, ponds, and terraces unless the structures have a determinable useful life.

What Property Cannot Be Depreciated?

Certain property cannot be depreciated, even if the requirements explained earlier are met. This includes the following.

Land. You can never depreciate the cost of land because land does not wear out, become obsolete, or get used up. The cost of land generally includes the cost of clearing, grading, planting, and landscaping. Although you cannot depreciate land, you can depreciate certain costs incurred in preparing land for business use. See chapter 1 of Publication 946.
Property placed in service and disposed of in the same year. Determining when property is placed in service is explained later.
Equipment used to build capital improvements. You must add otherwise allowable depreciation on the equipment during the period of construction to the basis of your improvements.
Intangible property such as section 197 intangibles. This property does not have a determinable useful life and generally cannot be depreciated. However, see Amortization, later. Special rules apply to computer software (discussed below).
Certain term interests (discussed below).

Computer software

Computer software is not a section 197 intangible even if acquired in connection with the acquisition of a business, if it meets all of the following tests.

It is readily available for purchase by the general public.
It is subject to a nonexclusive license.
It has not been substantially modified.

If the software meets the tests above, it can be depreciated and may qualify for the section 179 deduction and the special depreciation allowance (if applicable), discussed later.

Certain term interests in property

You cannot depreciate a term interest in property created or acquired after July 27, 1989, for any period during which the remainder interest is held, directly or indirectly, by a person related to you. This rule does not apply to the holder of a term interest in property acquired by gift, bequest, or inheritance. For more information, see chapter 1 of Publication 946.

When Does Depreciation Begin and End?

You begin to depreciate your property when you place it in service for use in your trade or business or for the production of income. You stop depreciating property either when you have fully recovered your cost or other basis or when you retire it from service, whichever happens first.

Placed in Service

Property is placed in service when it is ready and available for a specific use, whether in a business activity, an income-producing activity, a tax-exempt activity, or a personal activity. Even if you are not using the property, it is in service when it is ready and available for its specific use.

Example —

You bought a planter for use in your farm business. The planter was delivered in December 2007 after harvest was over. You begin to depreciate the planter for 2007 because it was ready and available for its specific use in 2007, even though it will not be used until the spring of 2008.

If your planter comes unassembled in December 2007 and is put together in February 2008, it is not placed in service until 2008. You begin to depreciate it in 2008.

If your planter was delivered and assembled in February 2008 but not used until April 2008, it is placed in service in February 2008, because this is when the planter was ready for its specified use. You begin to depreciate it in 2008.

Fruit or nut trees and vines

If you acquire an orchard, grove, or vineyard before the trees or vines have reached the income-producing stage, and they have a preproductive period of more than 2 years, you must capitalize the preproductive-period costs under the uniform capitalization rules (unless you elect not to use these rules). See chapter 6 for information about the uniform capitalization rules. Your depreciation begins when the trees and vines reach the income-producing stage (that is, when they bear fruit, nuts, or grapes in quantities sufficient to commercially warrant harvesting).

Immature livestock

Depreciation for livestock begins when the livestock reaches the age of maturity. If you acquire immature livestock for draft, dairy, or breeding purposes, your depreciation begins when the livestock reach the age when they can be worked, milked, or bred. When this occurs, your basis for depreciation is your initial cost for the immature livestock.

Idle Property

Continue to claim a deduction for depreciation on property used in your business or for the production of income even if it is temporarily idle. For example, if you stop using a machine because there is a temporary lack of a market for a product made with that machine, continue to deduct depreciation on the machine.

Cost or Other Basis Fully Recovered

You stop depreciating property when you have fully recovered your cost or other basis. This happens when your section 179 and allowed or allowable depreciation deductions equal your cost or investment in the property.

Retired From Service

You stop depreciating property when you retire it from service, even if you have not fully recovered its cost or other basis. You retire property from service when you permanently withdraw it from use in a trade or business or from use in the production of income because of any of the following events.

You sell or exchange the property.
You convert the property to personal use.
You abandon the property.
You transfer the property to a supplies or scrap account.
The property is destroyed.

For information on abandonment of property, see chapter 8. For information on destroyed property, see chapter 11 and Publication 547, Casualties, Disasters, and Thefts.

Can You Use MACRS To Depreciate Your Property?

You must use the Modified Accelerated Cost Recovery System (MACRS) to depreciate most business and investment property placed in service after 1986. MACRS is explained later under Figuring Depreciation Under MACRS.

You cannot use MACRS to depreciate the following property.

Property you placed in service before 1987. Use the methods discussed in Publication 534
Certain property owned or used in 1986. See Chapter 1 of Publication 946.
Intangible property.
Films, video tapes, and recordings.
Certain corporate or partnership property acquired in a nontaxable transfer.
Property you elected to exclude from MACRS.

For more information, see Chapter 1 of Publication 946.

What Is the Basis of Your Depreciable Property?

To figure your depreciation deduction, you must determine the basis of your property. To determine basis, you need to know the cost or other basis of your property.

Cost or other basis

The basis of property you buy is usually its cost plus amounts you paid for items such as sales tax, freight charges, and installation and testing fees. The cost includes the amount you pay in cash, debt obligations, other property, or services. There are times when you cannot use cost as basis. In these situations, the fair market value (FMV) or the adjusted basis of the property may be used.

Adjusted basis

To find your property's basis for depreciation, you may have to make certain adjustments (increases and decreases) to the basis of the property for events occurring between the time you acquired the property and the time you placed it in service.

Basis adjustment for depreciation allowed or allowable

After you place your property in service, you must reduce the basis of the property by the depreciation allowed or allowable, whichever is greater. Depreciation allowed is depreciation you actually deducted (from which you received a tax benefit). Depreciation allowable is depreciation you are entitled to deduct. If you do not claim depreciation you are entitled to deduct, you must still reduce the basis of the property by the full amount of depreciation allowable. If you deduct more depreciation than you should, you must reduce your basis by any amount deducted from which you received a tax benefit (the depreciation allowed). For more information, see chapter 6.

How Do You Treat Repairs and Improvements?

You generally deduct the cost of repairing business property in the same way as any other business expense. However, if a repair or replacement increases the value of your property, makes it more useful, or lengthens its life, you must treat it as an improvement and depreciate it. Treat improvements as separate depreciable property. See chapter 1 of Publication 946 for more information.

Improvements to rented property

You can depreciate permanent improvements you make to business property you rent from someone else.

Example —

You repair a small section on a corner of the roof of a barn that you rent to others. You deduct the cost of the repair as a business expense. However, if you replace the entire roof, the new roof is considered to be an improvement because it increases the value and lengthens the life for the property. You depreciate the cost of the new roof.

Do You Have To File Form 4562?

Use Form 4562 to claim your deduction for depreciation and amortization. You must complete and attach Form 4562 to your tax return if you are claiming any of the following.

A section 179 deduction for the current year or a section 179 carryover from a prior year.
Depreciation for property placed in service during the current year.
Depreciation on any vehicle or other listed property, regardless of when it was placed in service.
Amortization of costs that began in the current year.

For more information, see the Instructions for Form 4562.

How Do You Correct Depreciation Deductions?

If you deducted an incorrect amount of depreciation in any year, you may be able to make a correction by filing an amended return for that year. You can file an amended return to correct the amount of depreciation claimed for any property in any of the following situations.

You claimed the incorrect amount because of a mathematical error made in any year.
You claimed the incorrect amount because of a posting error made in any year, for example, omitting an asset from the depreciation schedule.
You have not adopted a method of accounting for the property.

If you are not allowed to make the correction on an amended return, you may be able to change your accounting method to claim the correct amount of depreciation. See the Instructions for Form 3115.

Section 179 Deduction

You can elect to recover all or part of the cost of certain qualifying property, up to a limit, by deducting it in the year you place the property in service. This is the section 179 deduction. You can elect the section 179 deduction instead of recovering the cost by taking depreciation deductions.

This part of the chapter explains the rules for the section 179 deduction. It explains what property qualifies for the deduction, what property does not qualify for the deduction, the limits that may apply, how to elect the deduction, and when you may have to recapture the deduction.

For more information, see chapter 2 of Publication 946.

What Property Qualifies?

To qualify for the section 179 deduction, your property must meet all the following requirements.

It must be eligible property.
It must be acquired for business use.
It must have been acquired by purchase.

Eligible Property

To qualify for the section 179 deduction, your property must be one of the following types of depreciable property.

Tangible personal property.
Other tangible property (except buildings and their structural components) used as:
1. An integral part of manufacturing, production, or extraction or of furnishing transportation, communications, electricity, gas, water, or sewage disposal services,
2. A research facility used in connection with any of the activities in (a) above, or
3. A facility used in connection with any of the activities in (a) for the bulk storage of fungible commodities.
Single purpose agricultural (livestock) or horticultural structures.
Storage facilities (except buildings and their structural components) used in connection with distributing petroleum or any primary product of petroleum.
Off-the-shelf computer software that is readily available for purchase by the general public, is subject to a nonexclusive lease, and has not been substantially modified.

Tangible personal property

Tangible personal property is any tangible property that is not real property. It includes the following property.

Machinery and equipment.
Property contained in or attached to a building (other than structural components), such as milk tanks, automatic feeders, barn cleaners, and office equipment.
Gasoline storage tanks and pumps at retail service stations.
Livestock, including horses, cattle, hogs, sheep, goats, and mink and other fur-bearing animals.

Facility used for the bulk storage of fungible commodities

A facility used for the bulk storage of fungible commodities is qualifying property for purposes of the section 179 deduction if it is used in connection with any of the activities listed earlier in item (2)(a). Bulk storage means the storage of a commodity in a large mass before it is used.

Grain bins

A grain bin is an example of a storage facility that is qualifying section 179 property. It is a facility used in connection with the production of grain or livestock for the bulk storage of fungible commodities.

Single purpose agricultural or horticultural structures

A single purpose agricultural (livestock) or horticultural structure is qualifying property for purposes of the section 179 deduction. Agricultural structure. A single purpose agricultural (livestock) structure is any building or enclosure specifically designed, constructed, and used for both the following reasons.

To house, raise, and feed a particular type of livestock and its produce.
To house the equipment, including any replacements, needed to house, raise, or feed the livestock.

For this purpose, livestock includes poultry. Single purpose structures are qualifying property if used, for example, to breed chickens or hogs, produce milk from dairy cattle, or produce feeder cattle or pigs, broiler chickens, or eggs. The facility must include, as an integral part of the structure or enclosure, equipment necessary to house, raise, and feed the livestock.

Horticultural structure

A single purpose horticultural structure is either of the following.

A greenhouse specifically designed, constructed, and used for the commercial production of plants.
A structure specifically designed, constructed, and used for the commercial production of mushrooms.

Use of structure

A structure must be used only for the purpose that qualified it. For example, a hog barn will not be qualifying property if you use it to house poultry. Similarly, using part of your greenhouse to sell plants will make the greenhouse nonqualifying property. If a structure includes work space, the work space can be used only for the following activities.

Stocking, caring for, or collecting livestock or plants or their produce.
Maintaining the enclosure or structure.
Maintaining or replacing the equipment or stock enclosed or housed in the structure.

Property Acquired by Purchase

To qualify for the section 179 deduction, your property must have been acquired by purchase. For example, property acquired by gift or inheritance does not qualify. Property acquired from a related person (that is, your spouse, ancestors, or lineal descendants) is not considered acquired by purchase.

Example —

Ken is a farmer. He purchased two tractors from his father. He placed both tractors in service in the same year he bought them. The tractors do not qualify as section 179 property because Ken and his father are related persons. He cannot claim a section 179 deduction for the cost of these machines.

What Property Does Not Qualify?

Land and improvements

Land and land improvements, such as buildings and other permanent structures and their components, are real property, not personal property and do not qualify as section 179 property. Land improvements include nonagricultural fences, swimming pools, paved parking areas, wharves, docks, bridges, and fences. However, agricultural fences do qualify as section 179 property. Similarly, field drainage tile also qualifies as section 179 property.

Excepted property

Even if the requirements explained in the preceding discussions are met, farmers cannot elect the section 179 deduction for the following property.

Certain property you lease to others (if you are a noncorporate lessor).
Certain property used predominantly to furnish lodging or in connection with the furnishing of lodging.
Air conditioning or heating units.
Property used by a tax-exempt organization (other than a tax-exempt farmers' cooperative) unless the property is used mainly in a taxable unrelated trade or business.
Property used by governmental units or foreign persons or entities (except property used under a lease with a term of less than 6 months).

How Much Can You Deduct?

Your section 179 deduction is generally the cost of the qualifying property. However, the total amount you can elect to deduct under section 179 is subject to a dollar limit and a business income limit. These limits apply to each taxpayer, not to each business. However, see Married individuals under Dollar Limits, later. See also the special rules for applying the limits for partnerships and S corporations, later, under Partnerships and S Corporations.

If you deduct only part of the cost of qualifying property as a section 179 deduction, you can generally depreciate the cost you do not deduct.

Use Part I of Form 4562 to figure your section 179 deduction.

Partial business use

When you use property for business and nonbusiness purposes, you can elect the section 179 deduction only if you use it more than 50% for business in the year you place it in service. If you used the property more than 50% for business, multiply the cost of the property by the percentage of business use. Use the resulting business cost to figure your section 179 deduction. Trade-in of other property. If you buy qualifying property with cash and a trade-in, its cost for purposes of the section 179 deduction includes only the cash you paid. For example, if you buy (for cash and a trade-in) a new tractor for use in your business, your cost for the section 179 deduction is the cash you paid. It does not include the adjusted basis of the old tractor you trade for the new tractor.

Example —

J-Bar Farms traded two cultivators having a total adjusted basis of $6,800 for a new cultivator costing $13,200. They received an $8,000 trade-in allowance for the old cultivators and paid $5,200 cash for the new cultivator. J-Bar also traded a used pickup truck with an adjusted basis of $8,000 for a new pickup truck costing $15,000. They received a $5,000 trade-in allowance and paid $10,000 cash for the new pickup truck.

Only the cash paid by J-Bar qualifies for the section 179 deduction. J-Bar's business costs that qualify for a section 179 deduction are $15,200 ($5,200 + $10,000).

Dollar Limits

The total amount you can elect to deduct under section 179 for most property placed in service in 2007 is $125,000. If you acquire and place in service more than one item of qualifying property during the year, you can allocate the section 179 deduction among the items in any way, as long as the total deduction is not more than $125,000. You do not have to claim the full $125,000.

Example —

This year, you bought and placed in service a tractor for $120,000 and a mower for $6,200 for use in your farming business. You elect to deduct the entire $6,200 for the mower and $118,800 for the tractor, a total of $125,000. This is the most you can deduct. Your $6,200 deduction for the mower completely recovered its cost. Your basis for depreciation is zero. The basis of your tractor for depreciation is $1,200. You figure this by subtracting the amount of your section 179 deduction, $118,800, from the cost of the tractor, $120,000.

Reduced dollar limit for cost exceeding $500,000. If the cost of your qualifying section 179 property placed in service in 2007 is over $500,000, you must reduce the dollar limit (but not below zero) by the amount of cost over $500,000. If the cost of your section 179 property placed in service during 2007 is $625,000 or more, you cannot take a section 179 deduction and you cannot carry over the cost that is more than $625,000.

Example —

This year, James Smith placed in service machinery costing $550,000. Because this cost is $50,000 more than $500,000, he must reduce his dollar limit to $75,000 ($125,000 - $50,000).

Limits for qualified section 179 GO Zone property

If you placed in service qualified section 179 GO Zone property (described below) in 2007, the amount of property for which you can make the election under section 179 is increased by the smaller of:

$100,000 or
The cost of the qualified section 179
GO Zone property placed in service during the year.

The amount for which you can make the election is reduced if the cost of all section 179 property placed in service during the year exceeds $500,000 increased by the smaller of:

$600,000 or
The cost of qualified section 179 GO Zone property placed in service during the year.

Qualified section 179 GO Zone property is section 179 property that is also qualified GO Zone property (described later under Claiming the Special Depreciation Allowance).

Limits for sport utility vehicles

The total amount you can elect to deduct for certain sport utility vehicles and certain other vehicles placed in service in 2007 is $25,000. This rule applies to any 4-wheeled vehicle primarily designed or used to carry passengers over public streets, roads, and highways that is rated at more than 6,000 pounds gross vehicle weight and not more than 14,000 pounds gross vehicle weight. For more information, see chapter 2 of Publication 946.

Limits for passenger automobiles

For a passenger automobile that is placed in service in 2007, the total section 179 and depreciation deduction is limited. See Do the Passenger Automobile Limits Apply later.

Married individuals

If you are married, how you figure your section 179 deduction depends on whether you file jointly or separately. If you file a joint return, you and your spouse are treated as one taxpayer in determining any reduction to the dollar limit, regardless of which of you purchased the property or placed it in service. If you and your spouse file separate returns, you are treated as one taxpayer for the dollar limit, including the reduction for costs over $500,000. You must allocate the dollar limit (after any reduction) equally between you, unless you both elect a different allocation. If the percentages elected by each of you do not total 100%, 50% will be allocated to each of you.

Joint return after separate returns

If you and your spouse elect to amend your separate returns by filing a joint return after the due date for filing your return, the dollar limit on the joint return is the lesser of the following amounts.

The dollar limit (after reduction for any cost of section 179 property over $500,000).
The total cost of section 179 property you and your spouse elected to expense on your separate returns.

Business Income Limit

The total cost you can deduct each year after you apply the dollar limit is limited to the taxable income from the active conduct of any trade or business during the year. Generally, you are considered to actively conduct a trade or business if you meaningfully participate in the management or operations of the trade or business.

Any cost not deductible in one year under section 179 because of this limit can be carried to the next year. See Carryover of disallowed deduction, later.

Taxable income

In general, figure taxable income for this purpose by totaling the net income and losses from all trades and businesses you actively conducted during the year. In addition to net income or loss from a sole proprietorship, partnership, or S corporation, net income or loss derived from a trade or business also includes the following items.

Section 1231 gains (or losses) as discussed in chapter 9.
Interest from working capital of your trade or business.
Wages, salaries, tips, or other pay earned as an employee.

In addition, figure taxable income without regard to any of the following.

The section 179 deduction.
The self-employment tax deduction.
Any net operating loss carryback or carryforward.
Any unreimbursed employee business expenses.

Two different taxable income limits

In addition to the business income limit for your section 179 deduction, you may have a taxable income limit for some other deduction (for example, charitable contributions). You may have to figure the limit for this other deduction taking into account the section 179 deduction. If so, complete the following steps.

Step	Action
1	Figure taxable income without the section 179 deduction or the other deduction.
2	Figure a hypothetical section 179 deduction using the taxable income figured in Step 1.
3	Subtract the hypothetical section 179 deduction figured in Step 2 from the taxable income figured in Step 1.
4	Figure a hypothetical amount for the other deduction using the amount figured in Step 3 as taxable income.
5	Subtract the hypothetical other deduction figured in Step 4 from the taxable income figured in Step 1.
6	Figure your actual section 179 deduction using the taxable income figured in Step 5.
7	Subtract your actual section 179 deduction figured in Step 6 from the taxable income figured in Step 1.
8	Figure your actual other deduction using the taxable income figured in Step 7.

Example —

On February 1, 2007, the XYZ farm corporation purchased and placed in service qualifying section 179 property that cost $125,000. It elects to expense the entire $125,000 cost under section 179. In June, the corporation gave a charitable contribution of $10,000. A corporation's limit on charitable contributions is figured after subtracting any section 179 deduction. The business income limit for the section 179 deduction is figured after subtracting any allowable charitable contributions. XYZ's taxable income figured without the section 179 deduction or the deduction for charitable contributions is $145,000. XYZ figures its section 179 deduction and its deduction for charitable contributions as follows.

Step 1. Taxable income figured without either deduction is $145,000.

Step 2. Using $145,000 as taxable income, XYZ's hypothetical section 179 deduction is $125,000.

Step 3. $20,000 ($145,000 - $125,000).

Step 4. Using $20,000 (from Step 3) as taxable income, XYZ's hypothetical charitable contribution (limited to 10% of taxable income) is $2,000.

Step 5. $143,000 ($145,000 - $2,000).

Step 6. Using $143,000 (from Step 5) as taxable income, XYZ figures the actual section 179 deduction. Because the taxable income is at least $125,000, XYZ can take a $125,000 section 179 deduction.

Step 7. $20,000 ($145,000 - $125,000).

Step 8. Using $20,000 (from Step 7) as taxable income, XYZ's actual charitable contribution (limited to 10% of taxable income) is $2,000.

Carryover of disallowed deduction

You can carry over for an unlimited number of years the cost of any section 179 property you elected to expense but were unable to because of the business income limit. The amount you carry over is used in determining your section 179 deduction in the next year. However, it is subject to the limits in that year. If you place more than one property in service in a year, you can select the properties for which all or a part of the cost will be carried forward. Your selections must be shown in your books and records.

Example —

Last year, Joyce Jones placed in service a machine that cost $8,000 and elected to deduct all $8,000 under section 179. The taxable income from her business (determined without regard to both a section 179 deduction for the cost of the machine and the self-employment tax deduction) was $6,000. Her section 179 deduction was limited to $6,000. The $2,000 cost that was not allowed as a section 179 deduction (because of the business income limit) is carried to this year.

This year, Joyce placed another machine in service that cost $9,000. Her taxable income from business (determined without regard to both a section 179 deduction for the cost of the machine and the self-employment tax deduction) is $10,000. Joyce can deduct the full cost of the machine ($9,000) but only $1,000 of the carryover from last year because of the business income limit. She can carry over the balance of $1,000 to next year.

Partnerships and S Corporations

The section 179 deduction limits apply both to the partnership or S corporation and to each partner or shareholder. The partnership or S corporation determines its section 179 deduction subject to the limits. It then allocates the deduction among its partners or shareholders.

If you are a partner in a partnership or shareholder of an S corporation, you add the amount allocated from the partnership or S corporation to any section 179 costs not related to the partnership or S corporation and then apply the dollar limit to this total. To determine any reduction in the dollar limit for costs over $500,000, you do not include any of the cost of section 179 property placed in service by the partnership or S corporation. After you apply the dollar limit, you apply the business income limit to any remaining section 179 costs. For more information, see chapter 2 of Publication 946.

Example —

In 2007, Partnership P placed in service section 179 property with a total cost of $580,000. P must reduce its dollar limit by $80,000 ($580,000 - $500,000). Its maximum section 179 deduction is $45,000 ($125,000 - $80,000), and it elects to expense that amount. Because P's taxable income from the active conduct of all its trades or businesses for the year was $50,000, it can deduct the full $45,000. P allocates $20,000 of its section 179 deduction and $25,000 of its taxable income to John, one of its partners.

John also conducts a business as a sole proprietor and in 2007, placed in service in that business, section 179 property costing $14,000. John's taxable income from that business was $5,000. He elects to expense the $20,000 allocated from P, plus the $14,000 of his sole proprietorship's section 179 costs. However, John's deduction is limited to his business taxable income of $30,000 ($25,000 from P plus $5,000 from his sole proprietorship). He carries over $4,000 ($34,000 - $30,000) of the elected section 179 costs to 2008.

How Do You Elect the Deduction?

You elect to take the section 179 deduction by completing Part I of Form 4562.

If you elect the deduction for listed property, complete Part V of
Form 4562 before completing Part I.

File Form 4562 with either of the following:

Your original tax return (whether or not you filed it timely), or
An amended return filed within the time prescribed by law. An election made on an amended return must specify the item of section 179 property to which the election applies and the part of the cost of each such item to be taken into account. The amended return must also include any resulting adjustments to taxable income.

Revoking an election

An election (or any specification made in the election) to take a section 179 deduction for 2007 can be revoked without IRS approval by filing an amended return. The amended return must be filed within the time prescribed by law. The amended return must also include any resulting adjustments to taxable income (for example, allowable depreciation in that tax year for the item of section 179 property for which the election pertains.) Once made, the revocation is irrevocable.

When Must You Recapture the Deduction?

You may have to recapture the section 179 deduction if, in any year during the property's recovery period, the percentage of business use drops to 50% or less. In the year the business use drops to 50% or less, you include the recapture amount as ordinary income. You also increase the basis of the property by the recapture amount. Recovery periods for property are discussed later.

If you sell, exchange, or otherwise dispose of the property, do not figure the recapture amount under the rules explained in this discussion. Instead, use the rules for recapturing depreciation explained in chapter 9 under Section 1245 Property .
If the property is listed property, do not figure the recapture amount under the rules explained in this discussion when the percentage of business use drops to 50% or less. Instead, use the rules for recapturing depreciation explained in chapter 5 of Publication 946 under Recapture of Excess Depreciation .

Figuring the recapture amount

To figure the amount to recapture, take the following steps.

Figure the allowable depreciation for the section 179 deduction you claimed. Begin with the year you placed the property in service and include the year of recapture.
Subtract the depreciation figured in (1) from the section 179 deduction you actually claimed. The result is the amount you must recapture.

Example —

In January 2005, Paul Lamb, a calendar year taxpayer, bought and placed in service section 179 property costing $10,000. The property is not listed property. He elected a $5,000 section 179 deduction for the property and also elected not to claim a special depreciation allowance. He used the property only for business in 2005 and 2006. During 2007, he used the property 40% for business and 60% for personal use. He figures his recapture amount as follows.

Section 179 deduction claimed (2005)		$5,000
Minus: Allowable depreciation (instead of section 179 deduction):
2005	$1,250
2006	1,875
2007 ($1,250 × 40% (business))	500	3,625
2007 — Recapture amount		$1,375

Paul must include $1,375 in income for 2007.

Where to report recapture

Report any recapture of the section 179 deduction as ordinary income in Part IV of Form 4797 and include it in income on Schedule F (Form 1040).

Recapture for qualified section 179 GO Zone property

If any qualified section 179 GO Zone property ceases to be used in the GO Zone in a later year, you must recapture the benefit of the increased section 179 deduction as “other income.”

Claiming the Special Depreciation Allowance

For qualified property (defined below) placed in service in 2007, you can take an additional 50% special depreciation allowance. The allowance is an additional deduction you can take after any section 179 deduction and before you figure regular depreciation under MACRS. Figure the special depreciation allowance by multiplying the depreciable basis of the qualified property
by 50%.

What is Qualified Property?

For farmers, qualified property generally is qualified GO Zone property. This is depreciable property that meets the following requirements.

The property must be acquired by purchase after August 27, 2005. If a binding contract to acquire the property existed before August 28, 2005, the property does not qualify.
The property must be placed in service in the GO Zone during the tax year.
Substantially all of the use of the property must be in the GO Zone in the active conduct of your trade or business.
The original use of the property within the GO Zone must begin with you.

For more information, including a description of the areas in the GO Zone, and a list of qualified GO Zone property, see chapter 3 of Publication 946.

How Can You Elect Not To Claim the Allowance?

You can elect, for any class of property, not to deduct the special allowance for all property in such class placed in service during the tax year. To make the election, attach a statement to your return indicating the class of property for which you are making the election.

Generally, you must make the election on a timely filed tax return (including extensions) for the year in which you place the property in service. However, if you timely filed your return for the year without making the election, you still can make the election by filing an amended return within 6 months of the due date of the original return (not including extensions). Attach the election statement to the amended return. On the amended return, write “Filed pursuant to section 301.9100-2.”

Once made, the election may not be revoked without IRS consent.

If you elect not to have the special allowance apply, the property may be subject to an alternative minimum tax adjustment for depreciation.

When Must You Recapture an Allowance

When you dispose of property for which you claimed a special depreciation allowance, any gain on the disposition is generally recaptured (included in income) as ordinary income up to the amount of the special depreciation allowance previously allowed or allowable. For more information, see chapter 3 of Publication 946.

Figuring Depreciation Under MACRS

The Modified Accelerated Cost Recovery System (MACRS) is used to recover the basis of most business and investment property placed in service after 1986. MACRS consists of two depreciation systems, the General Depreciation System (GDS) and the Alternative Depreciation System (ADS). Generally, these systems provide different methods and recovery periods to use in figuring depreciation deductions.

To be sure you can use MACRS to figure depreciation for your property, see Can You Use MACRS To Depreciate Your Property , earlier.

This part explains how to determine which MACRS depreciation system applies to your property. It also discusses the following information that you need to know before you can figure depreciation under MACRS.

Property's recovery class.
Placed-in-service date.
Basis for depreciation.
Recovery period.
Convention.
Depreciation method.

Finally, this part explains how to use this information to figure your depreciation deduction.

Which Depreciation System (GDS or ADS) Applies?

Your use of either the General Depreciation System (GDS) or the Alternative Depreciation System (ADS) to depreciate property under MACRS determines what depreciation method and recovery period you use. You should use GDS unless you are specifically required by law to use ADS or you elect to use ADS.

Required use of ADS

You must use ADS for the following property.

All property used predominantly in a farming business and placed in service in any tax year during which an election not to apply the uniform capitalization rules to certain farming costs is in effect.
Listed property used 50% or less in a qualified business use. See Additional Rules for Listed Property later.
Any tax-exempt use property.
Any tax-exempt bond-financed property.
Any property imported from a foreign country for which an Executive Order is in effect because the country maintains trade restrictions or engages in other discriminatory acts.
Any tangible property used predominantly outside the United States during the year.

If you are required to use ADS to depreciate your property, you cannot claim the special depreciation allowance.

Electing ADS

Although your property may qualify for GDS, you can elect to use ADS. The election generally must cover all property in the same property class you placed in service during the year. However, the election for residential rental property and nonresidential real property can be made on a property-by-property basis. Once you make this election, you can never revoke it. You make the election by completing line 20 in Part III of Form 4562.

Which Property Class Applies Under GDS?

The following is a list of the nine property classes under GDS.

3-year property.
5-year property.
7-year property.
10-year property.
15-year property.
20-year property.
25-year property.
Residential rental property.
Nonresidential real property.

See Which Property Class Applies Under GDS in chapter 4 of Publication 946 for examples of the types of property included in each class.

What Is the Placed-in-Service Date?

You begin to claim depreciation when your property is placed in service for use either in a trade or business or for the production of income. The placed-in-service date for your property is the date the property is ready and available for a specific use. It is therefore not necessarily the date it is first used. If you converted property held for personal use to use in a trade or business or for the production of income, treat the property as being placed in service on the conversion date. See Placed in Service under When Does Depreciation Begin and End, earlier, for examples illustrating when property is placed in service.

What Is the Basis for Depreciation?

The basis for depreciation of MACRS property is the property's cost or other basis multiplied by the percentage of business/investment use. Reduce that amount by any credits and deductions allocable to the property. The following are examples of some of the credits and deductions that reduce basis.

Any deduction for section 179 property.
Any deduction for removal of barriers to the disabled and the elderly.
Any disabled access credit, enhanced oil recovery credit, and credit for employer-provided childcare facilities and services.
Any special depreciation allowance.
Basis adjustment for investment credit property under section 50(c) of the Internal Revenue Code.

For information about how to determine the cost or other basis of property, see What Is the Basis of Your Depreciable Property, earlier. Also see chapter 6.

For additional credits and deductions that affect basis, see section 1016 of the Internal Revenue Code.

Which Recovery Period Applies?

The recovery period of property is the number of years over which you recover its cost or other basis. It is determined based on the depreciation system (GDS or ADS) used. See Table 7-1 for recovery periods under both GDS and ADS for some commonly used assets. For a complete list of recovery periods, see the Table of Class Lives and Recovery Periods in Appendix B of Publication 946.

House trailers for farm laborers

To depreciate a house trailer you supply as housing for those who work on your farm, use one of the following recovery periods if the house trailer is mobile (it has wheels and a history of movement).

A 7-year recovery period under GDS.
A 10-year recovery period under ADS.

However, if the house trailer is not mobile (its wheels have been removed and permanent utilities and pipes attached to it), use one of the following recovery periods.

A 20-year recovery period under GDS.
A 25-year recovery period under ADS.

Water wells

Water wells used to provide water for raising poultry and livestock are land improvements. If they are depreciable, use one of the following recovery periods.

A 15-year recovery period under GDS.
A 20-year recovery period under ADS.

The types of water wells that can be depreciated were discussed earlier in Irrigation systems and water wells under Property Having a Determinable Useful Life.

Which Convention Applies?

Under MACRS, averaging conventions establish when the recovery period begins and ends. The convention you use determines the number of months for which you can claim depreciation in the year you place property in service and in the year you dispose of the property. Use one of the following conventions.

The half-year convention.
The mid-month convention.
The mid-quarter convention.

For a detailed explanation of each convention, see Which Convention Applies in chapter 4 of Publication 946. Also see the Instructions for Form 4562.

Which Depreciation Method Applies?

MACRS provides three depreciation methods under GDS and one depreciation method under ADS.

The 200% declining balance method over a GDS recovery period.
The 150% declining balance method over a GDS recovery period.
The straight line method over a GDS recovery period.
The straight line method over an ADS recovery period.

Depreciation Table

The following table lists the types of property you can depreciate under each method. The declining balance method is abbreviated as DB and the straight line method is abbreviated as SL. Depreciation Table

¹Elective method

²See section 168(g)(6) of the Internal Revenue
Code

Property used in farming business

For personal property placed in service after 1988 in a farming business, you must use the 150% declining balance method over a GDS recovery period or you can elect one of the following methods.

The straight line method over a GDS recovery period.
The straight line method over an ADS recovery period.

¹ Not including communication equipment listed in other classes.

² Not including single purpose agricultural or horticultural structures.

³ Used by logging and sawmill operators for cutting of timber.

⁴ For property placed in service after May 12, 1993; for property placed in service before May 13, 1993,
the recovery period is 31.5 years.

For property placed in service before 1999, you could have elected to use the 150% declining balance method using the ADS recovery periods for certain property classes. If you made this election, continue to use the same method and recovery period for that property.

Real property

You can depreciate real property using the straight line method under either GDS or ADS.

Switching to straight line

If you use a declining balance method, you switch to the straight line method in the year it provides an equal or greater deduction. If you use the MACRS percentage tables, discussed later under How Is the Depreciation Deduction Figured, you do not need to determine in which year your deduction is greater using the straight line method. The tables have the switch to the straight line method built into their rates.

Fruit or nut trees and vines

Depreciate trees and vines bearing fruit or nuts under GDS using the straight line method over a 10-year recovery period.

ADS required for some farmers

If you elect not to apply the uniform capitalization rules to any plant shown in Table 6-1 of chapter 6 and produced in your farming business, you must use ADS for all property you place in service in any year the election is in effect. See chapter 6 for a discussion of the application of the uniform capitalization rules to farm property.

Electing a different method

As shown in the Depreciation Table, you can elect a different method for depreciation for certain types of property. You must make the election by the due date of the return (including extensions) for the year you placed the property in service. However, if you timely filed your return for the year without making the election, you can still make the election by filing an amended return within 6 months of the due date of your return (excluding extensions). Attach the election to the amended return and write “Filed pursuant to section 301.9100-2” on the election statement. File the amended return at the same address you filed the original return. Once you make the election, you cannot change it. If you elect to use a different method for one item in a property class, you must apply the same method to all property in that class placed in service during the year of the election. However, you can make the election on a property-by-property basis for residential rental and nonresidential real property.

Straight line election

Instead of using the declining balance method, you can elect to use the straight line method over the GDS recovery period. Make the election by entering “S/L” under column (f) in Part III of Form 4562.

ADS election

As explained earlier under Which Depreciation System (GDS or ADS) Applies, you can elect to use ADS even though your property may come under GDS. ADS uses the straight line method of depreciation over the ADS recovery periods, which are generally longer than the GDS recovery periods. The ADS recovery periods for many assets used in the business of farming are listed in Table 7-1. Additional ADS recovery periods for other classes of property may be found in the Table of Class Lives and Recovery Periods in Appendix B of Publication 946.

How Is the Depreciation Deduction Figured?

To figure your depreciation deduction under MACRS, you first determine the depreciation system, property class, placed-in-service date, basis amount, recovery period, convention, and depreciation method that applies to your property. Then you are ready to figure your depreciation deduction. You can figure it in one of two ways.

You can use the percentage tables provided by the IRS.
You can figure your own deduction without using the tables.

Figuring your own MACRS deduction will generally result in a slightly different amount than using the tables.

Using the MACRS Percentage Tables

To help you figure your deduction under MACRS, the IRS has established percentage tables that incorporate the applicable convention and depreciation method. These percentage tables are in Appendix A of Publication 946.

Rules for using the tables

The following rules cover the use of the percentage tables.

You must apply the rates in the percentage tables to your property's unadjusted basis. Unadjusted basis is the same basis amount you would use to figure gain on a sale but figured without reducing your original basis by any MACRS depreciation taken in earlier years.
You cannot use the percentage tables for a short tax year. See chapter 4 of Publication 946 for information on how to figure the deduction for a short tax year.
You generally must continue to use them for the entire recovery period of the property.
You must stop using the tables if you adjust the basis of the property for any reason other than—
1. Depreciation allowed or allowable, or
2. An addition or improvement to the property, which is depreciated as a separate property.

Basis adjustment due to casualty loss

If you reduce the basis of your property because of a casualty, you cannot continue to use the percentage tables. For the year of the adjustment and the remaining recovery period, you must figure the depreciation yourself using the property's adjusted basis at the end of the year. See Figuring the Deduction Without Using the Tables in chapter 4 of Publication 946. Figuring depreciation using the 150% DB method and half-year convention. Table 7-2 has the percentages for 3-, 5-, 7-, and 20-year property. The percentages are based on the 150% declining balance method with a change to the straight line method. This table covers only the half-year convention and the first 8 years for 20-year property. See Appendix A in Publication 946 for complete MACRS tables, including tables for the mid-quarter and mid-month convention. The following examples show how to figure depreciation under MACRS using the percentages in Table 7-2.

Example —

During the year, you bought an item of 7-year property for $10,000 and placed it in service. You do not elect a section 179 deduction for this property. In addition, the property is not qualified property for purposes of the special depreciation allowance. The unadjusted basis of the property is $10,000. You use the percentages in Table 7-2 to figure your deduction.

Since this is 7-year property, you multiply $10,000 by 10.71% to get this year's depreciation of $1,071. For next year, your depreciation will be $1,913 ($10,000 × 19.13%).

Example —

You had a barn constructed on your farm at a cost of $20,000. You placed the barn in service this year. You elect not to claim the special depreciation allowance. The barn is 20-year property and you use the table percentages to figure your deduction. You figure this year's depreciation by multiplying $20,000 (unadjusted basis) by 3.75% to get $750. For next year, your depreciation will be $1,443.80 ($20,000 × 7.219%).

Table 7-2. 150% Declining Balance Method (Half-Year Convention)

Year	3-Year		5-Year		7-Year		20-Year
1	25.0	%	15.00	%	10.71	%	3.750	%
2	37.5		25.50		19.13		7.219
3	25.0		17.85		15.03		6.677
4	12.5		16.66		12.25		6.177
5			16.66		12.25		5.713
6			8.33		12.25		5.285
7					12.25		4.888
8					6.13		4.522

Figuring depreciation using the straight line method and half-year convention. The following table has the straight line percentages for 3-, 5-, 7-, and 20-year property using the half-year convention. The table covers only the first 8 years for 20-year property. See Appendix A in Publication 946 for complete MACRS tables, including tables for the mid-quarter and mid-month convention. Table 7-3. Straight Line Method (Half-Year Convention)

Year	3-Year		5-Year		7-Year		20-Year
1	16.67	%	10	%	7.14	%	2.5	%
2	33.33		20		14.29		5.0
3	33.33		20		14.29		5.0
4	16.67		20		14.28		5.0
5			20		14.29		5.0
6			10		14.28		5.0
7					14.29		5.0
8					7.14		5.0

The following example shows how to figure depreciation under MACRS using the straight line percentages in the table.

Example —

If in Example 2, earlier, you had elected the straight line method, you figure this year's depreciation by multiplying $20,000 (unadjusted basis) by 2.5% to get $500. For next year, your depreciation will be $1,000
($20,000 × 5%).

Figuring Depreciation Without the Tables

If you are required to or would prefer to figure your own depreciation without using the tables, see Figuring the Deduction Without Using the Tables in chapter 4 of Publication 946.

Figuring the Deduction for Property Acquired in a Nontaxable Exchange

If your property has a carryover basis because you acquired it in an exchange or involuntary conversion of other property or in a nontaxable transfer, you generally figure depreciation for the property as if the exchange, conversion, or transfer had not occurred.

Property acquired in a like-kind exchange or involuntary conversion. You generally must depreciate the carryover basis of MACRS property acquired in a like-kind exchange or involuntary conversion over the remaining recovery period of the property exchanged or involuntarily converted. You also generally continue to use the same depreciation method and convention used for the exchanged or involuntarily converted property. This applies only to acquired property with the same or a shorter recovery period and the same or more accelerated depreciation method than the property exchanged or involuntarily converted. The excess basis, if any, of the acquired MACRS property is treated as newly placed in service MACRS property.

Election out

You can elect not to use the above rules. The election, if made, applies to both the acquired property and the exchanged or involuntarily converted property. If you make the election, figure depreciation by treating the carryover basis and excess basis, if any, for the acquired property as if placed in service the later of on the date you acquired it, or the time of the disposition of the exchanged or involuntarily converted property. For depreciation purposes, the adjusted basis of the exchanged or involuntarily converted property is treated as if it was disposed of at the time of the exchange or conversion.

When to make the election

You must make the election on a timely filed return (including extensions) for the year of replacement. Once made, the election may not be revoked without IRS consent. For more information and special rules, see chapter 4 of Publication 946.

Property acquired in a nontaxable transfer

You must depreciate MACRS property acquired by a corporation or partnership in certain nontaxable transfers over the property's remaining recovery period in the transferor's hands, as if the transfer had not occurred. You must continue to use the same depreciation method and convention as the transferor. You can depreciate the part of the property's basis in excess of its carried-over basis (the transferor's adjusted basis in the property) as newly purchased MACRS property. For information on the kinds of nontaxable transfers covered by this rule, see chapter 4 of Publication 946.

How Do You Use General Asset Accounts?

To make it easier to figure MACRS depreciation, you can group separate assets into one or more general asset accounts (GAAs). You can then depreciate all the assets in each account as a single asset. Each account must include only assets with the same asset class (if any), recovery period, depreciation method, and convention. You cannot include an asset if you use it in both a personal activity and a trade or business (or for the production of income) in the year in which you first place it in service.

After you have set up a GAA, you generally figure the depreciation for it by using the applicable depreciation method, recovery period, and convention for the assets in the GAA. For each GAA, record the depreciation allowance in a separate depreciation reserve account.

There are additional rules for grouping assets in a GAA, figuring depreciation for a GAA, disposing of GAA assets, and terminating GAA treatment. Special rules apply in determining the basis and figuring the depreciation deduction for MACRS property in a GAA acquired in a like-kind exchange or involuntary conversion.

When Do You Recapture MACRS Depreciation?

When you dispose of property you depreciated using MACRS, any gain on the disposition is generally recaptured (included in income) as ordinary income up to the amount of the depreciation previously allowed or allowable for the property.

What Is the Business-Use Requirement?

You can claim the section 179 deduction for listed property and depreciate listed property using GDS and a declining balance method, if the property meets the business-use requirement. To meet this requirement, listed property must be used predominantly (more than 50% of its total use) for qualified business use. To determine whether the business-use requirement is met, you must allocate the use of any item of listed property used for more than one purpose during the year among its various uses.

Do the Passenger Automobile Limits Apply?

The depreciation deduction (including the section 179 deduction) you can claim for a passenger automobile each year is limited. The passenger automobile limits are the maximum depreciation amounts you can deduct for a passenger automobile. They are based on the date you placed the vehicle in service. See chapter 5 of Publication 946 for tables that show the maximum depreciation deduction for passenger automobiles. Also see the Instructions for
Form 4562.

For information about deducting expenses for the business use of your passenger automobile, see chapter 4 in Publication 463.

Deductions for passenger automobiles acquired in a trade-in. Special rules apply in figuring the depreciation for a passenger automobile received in a like-kind exchange or involuntary conversion. See chapter 5 of Publication 946 and section 1.168(i)-6T(d)(3) of the regulations.

Depletion

Depletion is the using up of natural resources by mining, quarrying, drilling, or felling. The depletion deduction allows an owner or operator to account for the reduction of a product's reserves.

Who Can Claim Depletion?

If you have an economic interest in mineral property or standing timber (defined below), you can take a deduction for depletion. More than one person can have an economic interest in the same mineral deposit or timber.

You have an economic interest if both the following apply.

You have acquired by investment any interest in mineral deposits or standing timber.
You have a legal right to income from the extraction of the mineral or the cutting of the timber, to which you must look for a return of your capital investment.

A contractual relationship that allows you an economic or monetary advantage from products of the mineral deposit or standing timber is not, in itself, an economic interest. A production payment carved out of, or retained on the sale of, mineral property is not an economic interest.

Mineral property is each separate interest you own in each mineral deposit in each separate tract or parcel of land. You can treat two or more separate interests as one property or as separate properties. See section 614 of the Internal Revenue Code and the related regulations for rules on how to treat separate mineral interests.

Timber property is your economic interest in standing timber in each tract or block representing a separate timber account.

Figuring Depletion

There are two ways of figuring depletion.

Cost depletion.
Percentage depletion.

For mineral property, you generally must use the method that gives you the larger deduction. For standing timber, you must use cost depletion.

Cost Depletion

To figure cost depletion you must first determine the following.

The property's basis for depletion.
The total recoverable units of mineral in the property's natural deposit.
The number of units of mineral sold during the tax year.

You must estimate or determine recoverable units (tons, barrels, board feet, thousands of cubic feet, or other measure) using the current industry method and the most accurate and reliable information you can obtain.

Basis for depletion and total recoverable units are explained in chapter 9 of
Publication 535.

Number of units sold

You determine the number of units sold during the tax year based on your method of accounting. Use the following table to make this determination.

IF you use ...	THEN the units sold during the year are ...
The cash method of accounting	The units sold for which you receive payment during the tax year (regardless of the year of sale).
An accrual method of accounting	The units sold based on your inventories.

The number of units sold during the tax year does not include any units for which depletion deductions were allowed or allowable in earlier years.

Figuring the cost depletion deduction

Once you have figured your property's basis for depletion, the total recoverable units, and the number of units sold during the tax year, you can figure your cost depletion deduction by taking the following steps.
