Section 179 year-end playbook: how do you finance equipment and put it in service by December 31?
The deadline is about the equipment, not the paperwork. A week-by-week plan for getting equipment financed, delivered, installed, and documented before December 31, 2026, and what a few weeks’ slip costs you.

The fourth quarter is when Section 179 goes from a line in the tax code to a deadline. Tax advantages are one of the main reasons businesses finance equipment: in the Equipment Leasing & Finance Foundation’s Horizon Report, 51% named tax advantages as a top reason, behind only optimizing cash flow (62%) and protection from obsolescence (55%).
For tax years beginning in 2026, the IRS sets the Section 179 limit at $2,560,000, reduced dollar for dollar once qualifying purchases exceed $4,090,000 (Rev. Proc. 2025-32). For the basics, what qualifies, the income limit, vehicles, and bonus depreciation, start with what is Section 179? This guide is the year-end plan.
What does “placed in service” mean for Section 179?
The IRS rule is short: property is placed in service when it is ready and available for a specific use. Its own example in Publication 946 is a machine delivered in one year but not installed and operational until the next: it counts in the later year. If it had been ready and available when it was delivered, it would count in the earlier year even if it was not used until later.
In practice, that means:
- Delivered is not enough if the equipment still needs installation, electrical work, rigging, or setup before it can run. A machine sitting crated on December 31 is not in service.
- Vehicles should be titled, registered, and ready for the road.
- Software and computers should be installed and working, not just licensed.
- Used equipment counts as long as it is new to you and ready for use; private-party purchases also need the title transferred.
Keep a short paper trail for the in-service date, so your CPA does not have to reconstruct it in April:
- The delivery receipt and the signed delivery and acceptance form.
- The installation or commissioning sign-off, and any training date.
- The first job, ticket, or production run that used the equipment.
- Dated photos of the equipment installed and running.
- The invoice and your financing documents.
The year-end countdown, week by week
Lead times, holiday schedules, and the year-end rush in equipment finance all compress December. Work backward from a target in-service date of December 15, not December 31:
| When | What to do | Why then |
|---|---|---|
| Now to mid-October | Decide what the business actually needs. Get quotes with written lead times. Ask your CPA for a projected deduction and income limit. | Build-to-order and shipped equipment can take weeks to months. |
| By early November | Apply and get approved. Choose the structure: an equipment finance agreement or $1 buyout lease keeps the deduction with you. | Approvals are fast now; December is the busiest month in equipment finance. |
| Early to mid-November | Sign documents and place the order. Get delivery and installation dates in writing. | If the seller needs a deposit to start production, deposit funding can be released once documents are signed. |
| Late November to mid-December | Delivery, installation, training. Sign the delivery and acceptance form once it runs. | Leaves a two-week buffer for freight delays, parts, and holiday crews. |
| By December 31 | Equipment in service and documented. | This is the date that decides which tax year the deduction lands in. |
| Tax season | Your CPA elects Section 179 on Form 4562 with your return. | The election is not automatic; it is made by the return due date, including extensions. |
At Five West, most submissions get a first response within 1 to 2 business hours, application-only decisions often come the same business day, and funding follows in as little as 24 to 48 hours after documents are signed. Deals that need financial statements take longer, so start those first. The full process is in how equipment financing works.
How does financing work with Section 179 at year-end?
Structure decides it. With an equipment finance agreement or a $1 buyout lease, you are generally treated as the owner for tax purposes, so the full price can qualify for Section 179 even though you have made only a payment or two by December 31. With a true fair market value lease, the lessor owns the equipment, and you generally deduct the lease payments instead. If the deduction is the point, know which one you are signing; equipment lease vs. loan compares them side by side.
Financing also protects the cash you will want in January: estimated tax payments, payroll after the holidays, and the slow start most businesses see in the first quarter. Deferred and seasonal payment structures are available on many programs if your revenue is uneven.
What does a few weeks’ slip cost?
Take a $100,000 machine financed over 60 months at an assumed 9%. The payment is about $2,076 a month either way. What changes is when the deduction arrives:
| In service | Section 179 deduction | Tax value at an assumed 30% rate | Payments made in 2026 |
|---|---|---|---|
| December 15, 2026 | Up to $100,000 on the 2026 return | About $30,000, a year earlier | At most one or two |
| January 5, 2027 | Up to $100,000 on the 2027 return | About $30,000, a year later | None |
Illustration only, at an assumed rate and tax rate, subject to the income limit and your full tax picture. Not tax advice.
A three-week slip does not lose the deduction, but it pushes about $30,000 of tax value back a full year. If your income this year is high, that timing can matter more than the rate on the financing.
What should you confirm with your CPA before you buy?
- The income limit. Section 179 cannot exceed your taxable business income; the excess carries forward.
- The Section 179 and bonus depreciation mix. 100% bonus depreciation is available too, and your CPA picks the combination.
- Your state. Not every state follows the federal Section 179 rules.
- Vehicles. Passenger vehicles and heavy SUVs have their own caps; work trucks with no real personal use generally do not.
- Business use above 50%, now and in later years, to avoid recapture.
Year-end mistakes that cost the deduction
- Counting the order date. A December purchase order for a machine that arrives in February is a 2027 deduction.
- Leaving no buffer. A December 30 delivery date has no room for freight, parts, or an installer out for the holidays.
- Signing a fair market value lease and expecting the Section 179 deduction.
- Applying in December. Approvals are fast, but files that need financials, titles, or appraisals take longer, and December is crowded.
- Buying for the deduction alone. A deduction on equipment you do not need is still money spent. Decide on the equipment first, then let the deduction improve the math.
- Not documenting the in-service date. Reconstructing it in April is harder than writing it down in December.
The bottom line
Section 179 rewards businesses that plan the calendar, not just the purchase. Pick the equipment and get approved by early November, aim to have it running by mid-December, keep the paperwork that proves it, and let your CPA make the election. Financing lets you take the full deduction this year while the equipment pays for itself over the next several.
Frequently asked questions
What is the Section 179 deadline for 2026?
For a 2026 deduction, the equipment must be placed in service, ready and available for its use, by December 31, 2026, for a calendar-year business. The election itself is made on Form 4562 with your return, by the due date including extensions.
Does equipment have to be paid off to take Section 179?
No. Financing does not reduce the deduction. With an equipment finance agreement or a $1 buyout lease, you can generally deduct the full price in the year the equipment is placed in service, while paying for it over the term.
Does the purchase date or the delivery date count for Section 179?
Neither on its own. What counts is when the equipment is placed in service: ready and available for its specific use. Equipment delivered in December but not installed and operational until January counts in January.
Can I take Section 179 on leased equipment?
Generally yes with a $1 buyout lease, which is treated like a purchase. With a true fair market value lease, the lessor owns the equipment, and you generally deduct the lease payments instead.
What happens if delivery slips into January?
The deduction moves to the next tax year. It is not lost, but the tax value arrives a year later, which can matter if your income is high this year.
What is the Section 179 limit for 2026?
$2,560,000, reduced dollar for dollar once qualifying purchases placed in service during the year exceed $4,090,000. Bonus depreciation can cover amounts above the Section 179 limit.
How fast can I get equipment financing before year-end?
At Five West, most submissions get a first response within 1 to 2 business hours, application-only decisions often come the same business day, and funding follows in as little as 24 to 48 hours after documents are signed. Apply early: December is the busiest month in equipment finance.
