Section 179: Should You Finance or Lease to Maximize the Deduction?
By Christopher Chavez, Founder — Northwood Capital Group
Every fall, business owners ask the same question: if I buy this equipment before year-end, how much will it save me in taxes? The answer usually comes down to Section 179 — and to whether the equipment is financed, purchased cash, or leased. The structure changes the deduction, and the wrong structure can leave tens of thousands of dollars on the table.
What Section 179 actually does
Section 179 of the IRS tax code lets a business deduct the full purchase price of qualifying equipment in the year it's placed in service, instead of depreciating it over 5–7 years. On a $150,000 excavator in a 25% effective tax bracket, that's roughly $37,500 in tax savings recognized this year rather than spread out. For a profitable business closing out Q4, that's real money.
The catch: the equipment has to be purchased and placed in service by December 31. Not ordered. Delivered, installed, and ready to work.
Why financing beats paying cash for Section 179
This is the part most owners miss. Section 179 doesn't care whether you paid cash or financed — the deduction is the same either way. But if you finance, you get the full deduction this year while only writing a check for the down payment and a couple of monthly installments. Your working capital stays in the business, and the tax savings can exceed your first-year payments.
Example: a $150,000 machine, financed at $0 down over 60 months. By year-end you might have made $2,800 in payments. Your Section 179 deduction is still the full $150,000 — a ~$37,500 tax cut against $2,800 of cash out. That's the mechanic that makes year-end financing so aggressive for profitable operators.
Which structures qualify — and which don't
| Structure | Section 179 eligible? | How you deduct it |
|---|---|---|
| Cash purchase | Yes | Full price in year one |
| Finance loan (EFA) | Yes | Full price in year one + deduct interest |
| $1 buyout lease | Yes | Full price in year one (treated as purchase) |
| FMV lease | No | Lease payments expensed as rent over the term |
| TRAC lease (vehicles) | Usually yes | Treated as financing — confirm with your CPA |
If Section 179 is the reason you're buying now, an FMV lease is almost always the wrong tool. Use a finance loan or a $1 buyout lease.
Timing: what "placed in service by December 31" really means
The IRS standard is that the equipment must be available and ready for its intended use. A truck sitting at the dealer with paperwork done doesn't count; a truck delivered to your yard with plates and insurance does. For installed equipment (CNC, dental, imaging), the machine has to be set up and operational — not still in a crate.
Working backward from December 31, most advisors want:
- By mid-November: equipment quote finalized, financing application in.
- By late November: credit approval, documents signed.
- By mid-December: funding to the vendor, delivery scheduled.
- By December 31: equipment delivered, installed, and running.
Waiting until the last week of December is how deals slip into the next tax year. Vendors run out of inventory, installers get booked, shipping backs up. If year-end matters, start early.
A common mistake: over-deducting
Section 179 can't create a loss. The deduction is capped at your business's taxable income for the year (bonus depreciation can create a loss; Section 179 can't). If a $200,000 purchase would drop you into the red, the unused portion carries forward to next year. It's not lost, but it's not the immediate cash-flow win you might be planning for. Run the actual numbers with your CPA before signing.
Rules of thumb
- Profitable year and buying equipment anyway → finance before December 31.
- Wanted an FMV lease for the low payment → know you're giving up Section 179.
- Need the lowest payment AND the deduction → use a $1 buyout lease.
- Not profitable this year → the write-off carries forward; timing matters less.
- Always model the actual dollar impact with your CPA before signing.
