Here's a tax fact that surprises a lot of business owners: you can finance a piece of equipment — put little or nothing down, spread payments over five years — and still deduct the entire purchase price on this year's return under Section 179. Done right, the first-year tax savings can exceed your first year of loan payments. This guide covers how the deduction actually works with financed equipment, which lease structures qualify (and which don't), the current limits, and a worked example you can sanity-check with your CPA.
How Section 179 works when you finance
Section 179 lets a business elect to expense the full cost of qualifying equipment in the year it's placed in service, instead of depreciating it over 5–7 years. Qualifying property includes machinery, vehicles (with some caps), computers, software, furniture, and certain building improvements — new or used, as long as it's new to you and used more than 50% for business.
The part owners miss: the IRS doesn't care how you paid. Whether you wrote a check, used equipment financing, or signed an equipment finance agreement (EFA), you're the owner for tax purposes. You deduct the full purchase price this year while your actual cash outlay is just the down payment plus a few monthly payments.
That mismatch — full deduction now, payments spread over years — is why Section 179 and financing pair so well. You keep working capital in the business, the equipment starts generating revenue immediately, and the tax savings land in the same year you took delivery.
Interest on the loan is separately deductible as a business expense on top of the Section 179 deduction, subject to the usual business-interest rules.
Current limits: Section 179 and bonus depreciation
Two separate provisions can each get you to a full first-year write-off:
| Feature | Section 179 | Bonus depreciation |
|---|---|---|
| 2025 deduction limit | $2.5 million | No dollar cap |
| Phase-out | Begins above $4 million in purchases | None |
| Limited by taxable income? | Yes — can't create a loss (excess carries forward) | No — can create or increase a loss |
| New and used equipment? | Both (new to you) | Both (new to you) |
| Current rate | 100% of cost, up to the limit | 100% for qualifying property acquired and placed in service after Jan 19, 2025, under current law |
| Election | Asset-by-asset, amount-by-amount | Applies by asset class unless you elect out |
A few practical implications:
- Most small businesses never touch the caps. If you're buying $80,000 of trucks or $300,000 of machinery, you're nowhere near the $2.5 million limit.
- Section 179 can't create a taxable loss. If your business income is $60,000 and you buy $150,000 of equipment, Section 179 covers $60,000 and the excess carries forward — but bonus depreciation can absorb the rest and even generate a loss. This is exactly the kind of sequencing your CPA optimizes.
- Vehicles have special caps. Heavy SUVs (over 6,000 lbs GVWR) face a Section 179 cap of roughly $31,000 for 2025, though bonus depreciation may cover more. Trucks and vans with a bed or cargo area generally aren't capped the same way.
Financed vs. leased: which structures qualify
This is where owners get tripped up. The label on the contract matters less than the substance:
| Structure | Who deducts | Section 179 eligible for you? |
|---|---|---|
| Equipment loan / EFA | You own it; you depreciate | Yes |
| $1 buyout (capital/finance) lease | Treated as a purchase | Yes, typically |
| 10% PUT / fixed-price buyout lease | Usually treated as a purchase | Often yes — confirm with CPA |
| True FMV operating lease | Lessor owns and depreciates | No — but lease payments are deductible as an expense |
With a true Equipment Lease at fair market value, you're renting: the lessor takes the Depreciation, and you deduct each payment as an operating expense. That's still a tax benefit — just spread over the lease term instead of concentrated in year one. If a big current-year deduction is the goal, a loan, EFA, or $1 buyout lease is usually the right structure. Our guide on leasing vs. financing equipment breaks down the broader trade-offs.
Worked example: $150,000 machine, financed
Say you buy a $150,000 CNC machine on December 1 with 10% down and a 5-year Term Loan-style equipment loan at 10% APR on the $135,000 balance. Assume a combined federal and state marginal tax rate of 30% and enough taxable income to absorb the deduction.
| Item | Amount |
|---|---|
| Equipment cost (Section 179 deduction) | $150,000 |
| Tax savings at 30% marginal rate | $45,000 |
| Down payment | $15,000 |
| Monthly payment (approx.) | $2,868 |
| First 12 months of payments | ~$34,400 |
| Cash out in year one (down + payments) | ~$49,400 |
| Net year-one cash cost after tax savings | ~$4,400 |
The $45,000 in tax savings offsets nearly all of your first-year cash outlay — for a machine that's presumably generating revenue the whole time. That's the core logic of pairing Section 179 with financing: the deduction is front-loaded, the payments aren't.
Two honest caveats. First, this isn't free money — you gave up future depreciation deductions, so years two through five have higher taxable income than they would under normal depreciation. It's a timing benefit (a very valuable one, given the time value of money). Second, your actual savings depend on your marginal rate and taxable income; at a 22% rate the savings would be $33,000, not $45,000.

The deduction lands in the year the equipment is placed in service — installed, tested, and ready for use in your business by December 31. Not ordered. Not paid for. Not sitting on a truck.
That makes Q4 timing real:
- Delivery and installation lead times. A machine ordered December 15 that ships in January gets deducted next year, no matter when you signed the finance agreement.
- Financing lead times. Equipment loans often fund in a few days to a couple of weeks depending on deal size and documentation — see how long funding takes in our full equipment financing guide. Don't start a December 28 application expecting a December 31 in-service date on complex equipment.
- Partial-year doesn't matter. Equipment placed in service December 30 gets the same full Section 179 deduction as equipment placed in service in February. That's why Q4 is the busiest season for equipment purchases.
How to run this play before year-end
- Confirm the deduction with your CPA first. Verify you have the taxable income to use Section 179 (or that bonus depreciation covers the gap), that your state conforms, and which structure they prefer.
- Get the equipment quote and delivery timeline in writing. The placed-in-service date drives everything.
- Choose an ownership structure. Loan, EFA, or $1 buyout lease if you want the deduction; FMV lease if you'd rather expense payments and preserve flexibility.
- Shop the financing, not just the equipment. Rates, down payments, and terms vary widely by lender, credit profile, and equipment type. Through EQ Funding's marketplace, one application goes to a network of equipment lenders who compete for your deal, so you can compare offers side by side instead of taking the dealer's first quote.
- Document everything. Keep the invoice, finance agreement, and delivery/installation records — they establish cost basis and the in-service date if you're ever asked.
The bottom line: financing equipment and deducting it in full this year aren't in conflict — they're complementary. Structure the deal as a purchase, get it running by December 31, and let the tax savings do a big chunk of the heavy lifting on year-one cost. Just make sure your CPA signs off on the numbers before you sign the paperwork.
