Section 179 of the IRS code lets a business deduct the full purchase price of qualifying equipment in the year placed in service, up to an annual limit. For 2026, that limit is $1,220,000 with a phase-out starting at $3,050,000 of qualifying purchases. Financed equipment qualifies in the year placed in service even with minimal down payment.
The 2026 numbers
- Deduction limit: $1,220,000
- Phase-out threshold: $3,050,000 (dollar-for-dollar reduction above this)
- Bonus depreciation rate (after §179): 60% (phasing to 40% in 2025, 20% in 2026, 0% in 2027)
- Business income limitation: §179 cannot exceed taxable income; excess carries forward
Always confirm current-year limits with your CPA or the latest IRS Publication 946.
What qualifies
Most tangible business property:
- Trucks, trailers, vehicles over 6,000 lbs GVW (lighter vehicles have separate caps)
- Machinery and manufacturing equipment
- Office furniture and office equipment
- Computers, servers, and off-the-shelf software
- Certain improvements to non-residential real property (roofs, HVAC, fire protection, security)
- New AND used equipment (must be new to your business)
What does not qualify
- Real estate (land or buildings; though see qualified improvement property)
- Property used 50% or less for business
- Property received as a gift or by inheritance
- Property purchased from a related party
How financing interacts with §179
This is the key insight that makes financing tax-efficient: you can claim §179 on financed equipment in the year you place it in service, even if you only made a small down payment.
Example: You finance $200,000 of equipment with 10% down ($20,000 cash). You place it in service in December. You can claim a $200,000 §179 deduction on your tax return that year. At a 25% effective tax rate, that is $50,000 of tax savings on $20,000 of out-of-pocket cash. The financing-to-own structure essentially lets you accelerate tax benefits relative to actual cash outflow.
Section 179 vs bonus depreciation
Both reduce taxable income. The differences:
| Section 179 | Bonus depreciation | |
|---|---|---|
| Annual cap | $1.22M (2026) | None |
| Phase-out | At $3.05M of equipment purchases | None |
| Income limit | Cannot exceed taxable income | Can create or increase NOL |
| Per-item or total | Per-item election | All-or-nothing per asset class |
| Rate | 100% (up to cap) | 60% in 2026, phasing down |
Typical order: claim §179 first (100% up to cap), then bonus depreciation on the rest, then standard MACRS on what is left.
State conformity
Most states conform to federal §179, but some have lower caps or different rules. Check your state. Pennsylvania, for example, has had a much lower §179 cap historically (though that has changed).
Common mistakes
- Buying equipment in late December but not placing it in service until January (only year placed in service qualifies)
- Forgetting that vehicles under 6,000 lbs have a special §179 cap (~$12,400 in 2026)
- Claiming §179 above taxable income (excess carries forward but cannot create a loss)
- Not documenting the business-use percentage on mixed-use equipment
How to claim it
File IRS Form 4562 with your tax return for the year placed in service. List the equipment, cost, and elected §179 amount. See our how to claim Section 179 step-by-step guide.
