A tractor is a capital good when a business owns it and uses it to produce income over more than one year. That classification is what lets a farmer, landscaper, or construction contractor write the machine off against taxable income through depreciation, Section 179 expensing, or bonus depreciation. The same tractor sold to a homeowner or sitting on a dealer’s lot is not a capital good, and none of those tax benefits apply.
What Makes a Tractor a Capital Good
The IRS allows depreciation on property that meets four conditions: you own it, you use it in a business or income-producing activity, it has a determinable useful life, and it will last more than one year.1Internal Revenue Service. Topic No. 704, Depreciation A tractor used in a real business meets every one of those tests. It goes on the balance sheet as a non-current asset, and its cost is spread across the years it stays in service.
In farming, the tractor prepares soil, plants seeds, hauls materials, and powers harvesting equipment. The crops are the product sold; the tractor is the durable tool that makes the crops possible. Because the machine survives many seasons without being absorbed into what you sell, it sits squarely in the capital-good category. The same logic applies to landscaping companies, construction outfits, and municipal operations that run tractors for ongoing work.
When a Tractor Is Not a Capital Good
A homeowner who buys a compact tractor to mow acreage and grade a driveway is buying a consumer good. There is no business income being generated, so the tractor never appears on a business balance sheet and doesn’t qualify for depreciation.
A tractor sitting on a dealer’s lot is inventory, not capital equipment, because it is held for resale rather than put to productive use. Inventory is a current asset expected to convert to cash in the normal operating cycle. Only the end buyer who puts the tractor to work in a business converts it into a capital asset.
Mixed Business and Personal Use
Plenty of owners split a tractor between business and personal tasks. The IRS doesn’t force an all-or-nothing choice, but the split matters.
Business use has to exceed 50 percent for the tractor to qualify for Section 179 or accelerated depreciation at all.2Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses On a $60,000 tractor used 70 percent for business, $42,000 is the qualifying cost. Drop below 50 percent and you are limited to straight-line depreciation over a longer recovery period.
If business use clears 50 percent in the year you buy but falls to 50 percent or less in a later year, you lose accelerated depreciation going forward and must recapture the excess deductions already claimed. That recapture amount gets added back to gross income. A simple log of hours or days used for business versus personal tasks is the easiest way to defend your percentage if the IRS asks.
How Fast You Recover the Cost
Once a tractor qualifies as a business capital asset, the Modified Accelerated Cost Recovery System (MACRS) governs how quickly you deduct its cost. The recovery period depends on whether the tractor is new or used, and on what type of tractor it is.
- New farm machinery and equipment: 5-year recovery period under the General Depreciation System (GDS). The shorter timeline came in through the Tax Cuts and Jobs Act for property whose original use begins with you and that was placed in service after December 31, 2017.3Office of the Law Revision Counsel. 26 USC 168 – Accelerated Cost Recovery System
- Used farm machinery and equipment: 7-year recovery period under GDS.4Internal Revenue Service. Publication 225 (2025), Farmer’s Tax Guide
- Over-the-road tractor units: 3-year recovery period under GDS, whether new or used.4Internal Revenue Service. Publication 225 (2025), Farmer’s Tax Guide
The Alternative Depreciation System (ADS) uses a 10-year period for farm machinery and is required in narrow situations, such as property used predominantly outside the United States or property financed with tax-exempt bonds. Most domestic farms use GDS because the shorter timeline produces larger early deductions.
Section 179: Full Cost in Year One
Section 179 of the Internal Revenue Code lets you expense the entire cost of qualifying equipment in the year you place it in service, rather than spreading it across the MACRS recovery period.5Office of the Law Revision Counsel. 26 USC 179 – Election to Expense Certain Depreciable Business Assets For a tractor costing $85,000, that is an $85,000 deduction right away instead of $12,000 to $17,000 per year for several years.
The 2026 limits:
- Maximum deduction: $2,560,000 for qualifying property placed in service during the tax year.
- Phase-out threshold: the deduction begins to decrease dollar-for-dollar once total qualifying property placed in service exceeds $4,090,000.
Most farm and small-business tractor purchases fall well below those ceilings. Two practical constraints matter more. Your Section 179 deduction cannot exceed your taxable business income for the year, though unused amounts carry forward, and the tractor must be used more than 50 percent for business.2Internal Revenue Service. Publication 463 (2025), Travel, Gift, and Car Expenses Both new and used tractors qualify, which makes Section 179 useful whether you are buying off the dealer lot or picking up a secondhand machine at auction.4Internal Revenue Service. Publication 225 (2025), Farmer’s Tax Guide
Bonus Depreciation Back at 100 Percent
Bonus depreciation had been phasing down from 100 percent by 20 percentage points each year starting in 2023. The One Big Beautiful Bill Act reversed that. For qualifying business property, including farm equipment and machinery, purchased and placed in service after January 19, 2025, businesses can again deduct 100 percent of the cost in the first year.6Internal Revenue Service. One, Big, Beautiful Bill Provisions
Bonus depreciation and Section 179 overlap but are not identical. Section 179 is an election you make, it is capped at your business income, and unused portions carry forward. Bonus depreciation applies automatically to eligible property unless you elect out, has no income limitation, and can create or increase a net operating loss. For most tractor buyers, either route delivers a full first-year write-off. The difference shows up when business income is low relative to the purchase price: bonus depreciation keeps working past zero taxable income; Section 179 stops there.
What Happens When You Sell or Trade
The tax benefit of depreciation is not free. When you sell a tractor you have been depreciating, the IRS reclaims some of that benefit through depreciation recapture under Section 1245.7Office of the Law Revision Counsel. 26 USC 1245 – Gain From Dispositions of Certain Depreciable Property
Say you bought a tractor for $80,000 and claimed $80,000 in total depreciation through Section 179, bonus depreciation, or regular MACRS. Your adjusted tax basis is $0. Sell the tractor for $25,000, and the entire $25,000 is ordinary income, not a capital gain, because it represents depreciation you previously deducted. Ordinary rates are typically higher than long-term capital gains rates, so the difference is real.
Recapture applies regardless of how you dispose of the tractor, whether through a private sale, dealer trade-in, or auction.
Financing and Leasing
Buying with a loan does not change the tractor’s capital-good status. You still own the asset, it still goes on your balance sheet, and you still claim depreciation or Section 179 on the full purchase price in the year it is placed in service. Interest on the equipment loan is separately deductible as a business expense.8Internal Revenue Service. Topic No. 505, Interest Expense
Leasing is different, and the treatment depends on the type of lease:
- Operating lease. You do not own the tractor. Lease payments are deductible as ordinary business expenses, but you cannot claim depreciation or Section 179 because the asset belongs to the lessor. This fits short-term projects or fleets you want to swap often.
- Finance lease, also called a capital lease. The lease effectively transfers ownership to you. That happens when the lease covers most of the tractor’s useful life, the present value of payments approaches the tractor’s fair market value, or the lease includes a bargain purchase option. A finance lease is treated like a purchase for tax purposes, so you record the tractor as an asset and claim depreciation.
The line can be subtle. A lease that looks like a rental on paper but ends with a $1 buyout is almost certainly a finance lease in the IRS’s eyes, and it should be treated as an asset purchase from day one.
State Sales Tax Exemptions
Most states offer some form of sales tax exemption for farm equipment and machinery, though the specifics vary widely. Some fully exempt qualifying agricultural equipment; others offer partial exemptions or require a valid agricultural exemption certificate. Common requirements include deriving a minimum percentage of income from farming, using the equipment primarily in agricultural production, and registering with the state department of revenue or agriculture. Check your state’s rules before you buy, because claiming the exemption at the point of sale is far simpler than filing for a refund afterward.
