The fourth quarter is the strongest equipment buying window of the year. Manufacturers want to clear inventory before next year’s models arrive. Tax planning rewards in-service-by-year-end. Lenders compete for last-quarter volume. Here is how to use all three.
The three Q4 levers
1. Manufacturer year-end push
October through December is when dealers and manufacturers most aggressively discount current-model-year inventory. Reasons:
- New-model-year units start arriving and current-year units take floor space
- Annual sales targets close December 31 and dealers want bonus tier qualifying volume
- Floor-plan financing costs accumulate on aging inventory
Typical Q4 discounts on in-stock current-model-year equipment run 5% to 15% off list. Limited-edition or hard-to-find configurations may not discount as much. Common workhorse units often see the deepest cuts.
2. Section 179 placed-in-service deadline
To claim Section 179 for tax year 2025, equipment must be placed in service by December 31, 2025. The deduction is up to $1.25 million in 2025 with bonus depreciation at 40% on remaining basis.
Placed in service means delivered, set up, and ready for use. Not ordered. Not in transit. Ready to operate. For complex equipment with installation requirements (production lines, fabrication systems), back-solve the timeline:
- Manufacturer build time: 4 to 12 weeks
- Shipping: 1 to 4 weeks
- Installation: 1 to 4 weeks
- Commissioning and operator training: 1 to 2 weeks
Many capital equipment purchases need to be signed by Labor Day to be in-service by year-end. Last-minute Q4 deals usually require off-the-shelf or in-stock units.
3. Lender competition
December is the highest-volume month for equipment lending. Lenders push to hit annual targets, which often means:
- Slight rate concessions on prime credit deals
- Faster approvals to capture deals before competitors
- More flex on borderline credit profiles
- Looser documentation requirements on app-only deals
The Q4 timeline that works
| When | What to do |
|---|---|
| Late September | Confirm tax need with accountant. Determine target purchase size. |
| Early October | Run payment scenarios. Soft-pull prequalification. |
| Mid October | Spec the equipment. Get dealer quotes on in-stock units. |
| Late October / Early November | Negotiate price. Lock financing terms. |
| Mid November | Sign loan documents. Schedule delivery. |
| December | Take delivery. Place in service. Document in-service date. |
| January | Provide proof of in-service to your CPA for tax filing. |
What can derail year-end timing
Title and registration delays. Trucks and titled equipment need DMV processing. December is the slowest DMV month in many states. If your equipment requires titled registration, factor in 2 to 4 extra weeks.
Installation contractor availability. Electrical, plumbing, foundation work. Q4 is when contractors are wrapping up the year and may not have capacity in late December.
Manufacturer holiday shutdowns. Most manufacturers close for 1 to 2 weeks in late December. If you need parts, accessories, or in-house customization, the window closes earlier than you might expect.
Bank cutoff dates. Year-end financial reporting means lenders impose internal deadlines for funding. Many lenders stop funding new deals after December 23. Some stop at December 15.
If you cannot close in Q4
If timing slips, talk to your CPA about January placed-in-service treatment. The Section 179 limit usually adjusts upward year over year, and bonus depreciation, while phasing down, still applies. A January 2026 placement still gets significant first-year deductions.
If a tax-driven deal slips, you can still capture the Q4 manufacturer pricing by ordering in December for January delivery. You lose the current-year deduction but capture the inventory discount.
Common Q4 mistakes
Buying equipment you do not need just for the deduction. A $200,000 Section 179 deduction at a 28% rate is $56,000 in tax savings. That same deduction requires you to spend $200,000. If you would not buy the equipment in March, do not buy it in December.
Skipping the bid process to hit the deadline. Three quotes still beats one quote, even when the calendar is tight. The discount you negotiate often exceeds the financing rate difference.
Forgetting to budget for sales tax and registration. Soft costs and titling fees do not always finance cleanly. Confirm what is bundled in the financing and what you write a check for.
Start the Q4 process
If it is October or later and you are thinking about equipment, do these three things this week:
- Talk to your accountant about Section 179 capacity and 2025 tax position.
- Soft-pull prequalification to know your real rate range.
- Identify in-stock equipment, not custom-build, to leave time for in-service.
