The single most common question equipment lenders hear every November and December is some version of: 'if I finance this truck now, can I write off the whole thing this year?' The answer, for most qualifying equipment, is yes - and it's the reason equipment financing volume spikes hard in Q4.
Here's how Section 179 actually works alongside financed equipment, what the 2026 limits look like, and the year-end math that makes financing - rather than waiting and saving - the move for a lot of profitable businesses. As always with tax rules: confirm the specifics with your CPA before you rely on them.
What Section 179 actually does
Section 179 lets qualifying businesses deduct the full purchase price of eligible equipment in the year it's placed in service, rather than depreciating it slowly over several years. Crucially, this applies whether you paid cash or financed the purchase - what matters for the deduction is that the equipment is in service by December 31, not how much of it you've actually paid off.
That last point is the whole mechanism behind the year-end play: finance a $150,000 piece of equipment in November, make one or two monthly payments before year-end, and still deduct the full $150,000 against this year's taxable income.
The 2026 numbers to know
| Item | 2026 figure (confirm with your CPA) | Notes |
|---|---|---|
| Section 179 deduction limit | Just over $1.2M | Adjusted annually for inflation |
| Spending cap phase-out begins | Just over $3M | Deduction reduces dollar-for-dollar above this |
| Bonus depreciation | Applies to remaining basis | Rate has shifted in recent years - verify current % |
| Placed-in-service deadline | December 31, 2026 | Equipment must be usable, not just purchased |
Why financing beats waiting-and-saving, for the right business
Say a profitable business finances a $120,000 truck in November with 10% down. They've paid roughly $12,000 out of pocket plus one or two monthly payments - call it $15,000 total cash out the door by December 31 - but they deduct the full $120,000 against this year's taxable income.
At a combined federal and state tax rate around 30%, that deduction is worth roughly $36,000 in tax savings, against $15,000 of actual cash spent so far. The tax shield alone can exceed the cash outlay in year one, which is the math that makes financing - rather than saving up to pay cash next year - the better move for a business that's already profitable and needs the equipment.

What do you need funding for?
What equipment actually qualifies
- Most tangible business equipment: trucks, trailers, machinery, lifts, diagnostic tools, computers and certain software
- Both new and used equipment qualify, as long as it's new to your business
- The equipment must be used more than 50% for business purposes
- Some vehicles have specific caps and rules (heavy SUVs and trucks are treated differently than passenger cars) - this is a detail to confirm with your CPA before assuming full eligibility
The timing detail that trips people up
'Placed in service' means the equipment is actually usable in your business, not just delivered or invoiced. A truck sitting unregistered in a lot on December 31 may not qualify for this tax year. If timing is tight, confirm what counts as placed-in-service for your specific equipment with your CPA before you assume the deduction applies.
Financing structure matters for the deduction
A standard equipment loan or a $1 buyout lease both typically qualify for Section 179 treatment, since you're building equity toward ownership. A fair-market-value (FMV) lease, where you're essentially renting with an option to buy later, is usually treated differently for tax purposes and may not qualify the same way. If the tax deduction is part of your reason for financing now, the structure you choose matters as much as the timing.
Don't let the tax tail wag the business dog
Section 179 makes financing equipment you already need meaningfully cheaper - it shouldn't be the reason to buy equipment you don't need. The deduction only has value against real taxable profit, and financing a payment you can't comfortably carry to chase a write-off is a bad trade even with the tax savings included.

FAQ
Can I take the Section 179 deduction if I financed the equipment instead of paying cash?+
Yes - the deduction is based on the full purchase price of qualifying equipment placed in service, regardless of whether you paid cash or financed it. This is confirmed by your CPA against your specific tax situation, but financed equipment is generally treated the same as cash-purchased equipment for this purpose.
What's the difference between Section 179 and bonus depreciation?+
Section 179 lets you choose which qualifying purchases to deduct up to the annual limit, while bonus depreciation typically applies more broadly to remaining basis after Section 179 is applied. Many businesses use both together - your CPA can model which combination fits your year.
Does used equipment qualify for Section 179?+
Yes, used equipment qualifies as long as it's new to your business and meets the other requirements. This is one reason used equipment financing sees a similar year-end push as new equipment purchases.
What happens if the equipment isn't delivered until January?+
It generally won't qualify for the current tax year's deduction - Section 179 requires the equipment to be placed in service by December 31. If timing is close, confirm delivery and placed-in-service dates with both your lender and your CPA well before the deadline.
Is Dealerun able to advise on my specific Section 179 eligibility?+
No - Dealerun is a funding marketplace, not a tax advisor. We can move quickly to get qualifying equipment financed and placed in service before year-end, but always confirm your specific deduction eligibility and amount with your CPA.
