Calculate annual tax deductions and book value for farm equipment using straight-line, double declining balance, or IRS MACRS methods.
Farm equipment depreciation is one of the largest tax deductions available to agricultural businesses. Understanding how to maximize your deduction — whether through standard depreciation methods or Section 179 expensing — can significantly reduce your tax burden in equipment-purchase years. This calculator generates a complete year-by-year depreciation schedule for your equipment.
Depreciation is the method by which the IRS allows businesses to deduct the cost of capital assets (equipment, machinery, buildings) over time rather than all in one year. For farm equipment, the IRS designates most machinery as "7-year property" under the Modified Accelerated Cost Recovery System (MACRS), meaning the cost is recovered over 8 tax years using front-loaded percentages.
The three main depreciation methods:
Section 179 Expensing: Farmers can elect to deduct the full cost of qualifying farm equipment in the year of purchase under Section 179 of the IRS code, rather than depreciating it over multiple years. The Section 179 deduction limit for 2024 is $1,160,000 (indexed annually for inflation), with a phase-out beginning at $2,890,000 in total property placed in service. This is an extremely powerful tool for reducing tax liability in high-income years — buying a $150,000 tractor in December and deducting the full cost that year can result in tax savings of $30,000–$55,000 depending on your effective tax rate.
Bonus depreciation: In addition to Section 179, the Tax Cuts and Jobs Act allowed 100% bonus depreciation for qualifying farm equipment through 2022. As of 2024, bonus depreciation is phased down to 60% and continues phasing down each year. Consult your tax advisor for the current rate, as it changes annually.
Most farm machinery and equipment is classified as 7-year property under MACRS (IRS Publication 946). This includes tractors, combines, planters, tillage equipment, and most farm implements. Grain bins and single-purpose agricultural structures are 10-year or 20-year property. Fences are 7-year property. Land is never depreciable. Breeding cattle and hogs are typically 5-year property.
Section 179 is almost always better if you have sufficient taxable income to absorb the deduction — it generates the maximum tax deferral. However, Section 179 deductions cannot exceed your net taxable income from active business activities, and unused Section 179 can be carried forward. MACRS provides steady deductions even in low-income years. Discuss timing with your CPA before year-end.
Yes — depreciation applies to both new and used equipment purchased for business use. Section 179 and bonus depreciation also apply to used equipment (as of the Tax Cuts and Jobs Act), making used equipment purchases just as tax-advantageous as new in most cases.
When you sell depreciated equipment, you may owe depreciation recapture tax under Section 1245. The IRS "recaptures" the depreciation deductions you took by taxing the gain up to the amount of depreciation previously deducted as ordinary income (rather than capital gains rates). The remaining gain above the original cost basis is taxed at capital gains rates. Recapture tax is a frequently overlooked cost of selling farm equipment.
Farm vehicles used exclusively for agricultural purposes are generally 5-year property under MACRS. However, if a vehicle is used for both personal and business purposes, the business-use percentage must be documented (mileage log) and only the business portion is deductible. "Listed property" rules impose additional limitations on SUVs and passenger vehicles used for business. Consult your CPA for vehicle-specific depreciation rules.
