Section 179 for Farm Equipment: Tractors, Combines & Implements (2026 Guide)

Farming is one of the best fits for Section 179 in the entire tax code. Tractors, combines, planters, sprayers, tillage tools — and even most breeding livestock — all qualify, and field machinery sidesteps the passenger-vehicle limits that complicate truck deductions. For 2026 you can expense up to $2,560,000 of qualifying property (phasing out only above $4,090,000 in total purchases), with permanent 100% bonus depreciation as a backup. Here is how it works for row-crop and cattle operations.

What qualifies on the farm

Eligible property includes most farm machinery and equipment — tractors, combines, planters, sprayers, balers, grain carts, irrigation equipment — plus single-purpose agricultural structures and most breeding livestock. The requirements are the standard ones:

• Tangible, depreciable property used in your farming business
• Used more than 50% for business
• Acquired by purchase — not gifted, inherited, or bought from a related party
• Placed in service during the tax year

Land never qualifies, and general-purpose farm buildings do not either. But for most operations, the Section 179 ceiling is a non-issue — only very large operations buying millions in equipment in a single year need to watch the $4,090,000 phase-out threshold.

Why farm machinery beats the vehicle rules

A tractor or combine is not a passenger automobile under §280F, so the luxury-auto limits that cap business cars at $20,300 in year one simply never apply. There is also no equivalent of the $32,000 heavy-SUV cap for field equipment — a $400,000 combine can be fully expensed in year one if your farm income supports it. (Remember that Section 179 cannot create a net operating loss; excess carries forward, and bonus depreciation has no income limit.)

Your farm pickup is a different animal. Trucks used as a means of transportation are listed property: you need more than 50% business use, contemporaneous mileage substantiation, and the 6,000-lb GVWR rules apply — though a pickup with a 6-foot-plus bed is exempt from the heavy-SUV cap. Do not treat the farm truck with the same casualness as the tractor; the IRS audits vehicle substantiation far more aggressively.

New vs. used: the recovery-period difference

Under MACRS, new farm machinery (original use commencing with you, placed in service after 2017) is 5-year property; used farm machinery is 7-year property. In practice this rarely matters, because both Section 179 and 100% bonus depreciation let you expense the full cost in year one regardless — and both apply to used property that is new to you. The used market is where the deduction-per-dollar math is often best: the same $90,000 write-off on a $90,000 used tractor costs far less cash than on a $180,000 new one.

Worked example: $150,000 new combine

You buy a new $150,000 combine in 2026 for a row-crop operation, 100% farm use:

• Section 179: the full $150,000 — no passenger-vehicle cap, no SUV cap, nowhere near the $2,560,000 limit.
• First-year deduction: $150,000. At a 22% marginal rate, that is roughly $33,000 in tax savings in year one.
• If farm income is thin this year, the unused Section 179 carries forward — or use bonus depreciation, which has no taxable-income limit.

Cattle operations get the same treatment on machinery, and purchased breeding livestock generally qualifies too — one more reason to run the numbers before year-end rather than after.

Watch the exit, too

Farm equipment is subject to the same Section 1245 recapture as any business property: sell the combine later for more than its (near-zero) adjusted basis, and the gain up to your depreciation is ordinary income. And if a machine’s business use ever drops to 50% or below, excess depreciation comes back as income on Form 4797. Keep use records even for field equipment — “it never leaves the farm” is a strong fact pattern, but records beat memory in an audit.
