Depreciation usually starts when the property is ready and available for its specific business use—not simply when it is bought—and the asset’s classification, use, basis, and tax-year rules determine how the deduction works. Land itself is not depreciable.
Which farm property can be depreciated?
Under the IRS Farmer’s Tax Guide, Publication 225 (2025), property generally must be owned by the taxpayer, used in a business or income-producing activity, have a determinable useful life, and last substantially beyond the year it is placed in service. Property that wears out, decays, is used up, becomes obsolete, or loses value from natural causes may have a determinable useful life. Many tangible farm assets can qualify, but the facts and classification of the individual property matter.
- Land: Land is generally not depreciable. Costs to prepare land for a center-pivot irrigation system are not depreciable either.
- Irrigation and water assets: Certain irrigation systems and water wells may qualify if they have determinable useful lives. Earthen dams, ponds, and terraces generally do not qualify unless they have determinable useful lives.
- Livestock: Purchased animals held for draft, breeding, or dairy purposes may be depreciable if they are not inventory. Raised livestock generally has no depreciable basis when the costs of raising it were deducted rather than capitalized, subject to the rules in Publication 225.
Depreciation applies to the business or income-producing use of property; personal use and other facts can affect the amount that may be recovered. A tax adviser can help determine how a particular asset should be classified and what basis is eligible.
When does depreciation begin?
The IRS says, “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.” In practice, placed in service means the asset is ready and available for its specific use. The purchase, delivery, and placed-in-service dates can differ, and depreciation may begin once the asset is ready even if it is not actively being used at that moment.
#1 Best Overall
Depreciation generally ends when the asset’s basis has been fully recovered or the property is retired from service, whichever happens first. The placed-in-service date is therefore important to retain with the asset’s other records.
How many years do common farm assets take to depreciate?
The IRS’s 2025 farm-property table lists the following recovery periods. GDS and ADS are the two depreciation-system columns in that table; the applicable system and the correct property class depend on the asset and the taxpayer’s circumstances. These are examples, not a substitute for classifying the actual property or checking the table’s footnotes.
| Farm property | GDS recovery period | ADS recovery period |
|---|---|---|
| New farm machinery and equipment | 5 years | 10 years |
| Used farm machinery and equipment | 7 years | 10 years |
| Farm buildings, excluding single-purpose agricultural or horticultural structures | 20 years | 25 years |
| Single-purpose agricultural structures | 10 years | 15 years |
| Grain bins | 7 years | 10 years |
| Cattle for dairy or breeding | 5 years | 7 years |
| Hogs for breeding | 3 years | 3 years |
| Water wells, if depreciable | 15 years | 20 years |
| Trees or vines bearing fruits or nuts | 10 years | 20 years |
Publication 225 (2025) provides the farm-specific examples. For the detailed depreciation rules and classification guidance, consult IRS Publication 946 and Form 4562. A label such as “farm equipment” alone may not be enough to establish the right class or recovery period.
Can a farm deduct the full cost in the first year?
Sometimes, but not automatically. Section 179 and special depreciation allowances can accelerate deductions for qualifying property. Eligibility, acquisition and placed-in-service dates, business use, exceptions, and elections all matter, and the largest possible first-year deduction is not necessarily the best choice for every taxpayer.
Section 179 for property placed in service in 2025
For property placed in service during 2025, Publication 225 states a maximum section 179 deduction of $2,500,000 for most qualifying property. That limit is reduced by the amount qualifying property placed in service during the year exceeds $4,000,000. The guide also gives a separate maximum of $31,300 for qualifying sport utility vehicles. These are 2025 amounts, not permanent limits.
Special depreciation for qualifying property
The 2025 guide describes a 100% special depreciation allowance for certain qualified property acquired and placed in service after January 19, 2025. It also describes different treatment for certain property acquired before that date, specified plants, and qualified production property. The allowance does not apply to every farm purchase: the property must meet the relevant tests, and exceptions and elections may affect the result. Check the current-year IRS rules for the specific asset and transaction.

For eligibility, elections, methods, and calculations, use Publication 946 and Form 4562. The IRS also lists farm-focused tax resources on its forms and publications page for farmers.

The IRS advises keeping depreciation records with permanent property records rather than filing them with the tax return. A useful asset file can include:

- Purchase or other acquisition documents and support for the asset’s basis.
- A description of the asset and the classification used for depreciation.
- Business-use share, acquisition date, and placed-in-service date.
- Depreciation method, elections, Form 4562 filings, and depreciation claimed in prior years.
- Documents related to a later sale, exchange, or retirement from service.
These records help support depreciation claimed in both current and prior years. Form 4562 is used for depreciation reporting; Publication 946 provides the fuller rules.
What happens when depreciated farm property is sold?
When property depreciated under MACRS is disposed of, gain is generally recaptured as ordinary income up to the depreciation previously allowed or allowable, according to Publication 225. The actual tax result depends on the asset and the transaction. Before selling or otherwise disposing of depreciated property, review the transaction’s reporting and recapture treatment with a tax professional.
Federal tax scope
This guidance describes U.S. federal rules as presented in the IRS’s 2025 Farmer’s Tax Guide, which is for preparing 2025 returns. It does not establish how a particular farm should classify an asset or whether state tax rules conform to federal treatment. Check the rules for the relevant tax year, asset use, basis, dates, and elections before filing.
