Year-end equipment purchases are driven primarily by tax timing. The Section 179 deduction and bonus depreciation require equipment to be placed in service by December 31. Missing the deadline by a day pushes the deduction to the next tax year.
What “placed in service” means
Placed in service is a specific IRS term. It means the equipment is:
- Delivered to your business location
- Installed and set up
- Tested and confirmed operational
- Available for the intended business use
Equipment that was ordered but not delivered does not qualify. Equipment that was delivered but not yet installed does not qualify. Equipment that is operational but in storage waiting for a project to start in January is in a gray area; document operational readiness if you intend to claim it.
The hard deadlines
| Milestone | Latest typical date for current-tax-year claim |
|---|---|
| Equipment spec finalized | Mid-October for custom builds, mid-November for in-stock |
| Financing application submitted | Late November for full-doc deals, mid-December for app-only |
| Loan documents signed | Mid-December |
| Equipment delivery | December 15 to 23, depending on installation requirements |
| Installation complete | December 31 |
| In-service documentation | December 31 |
Lenders typically stop funding new deals between December 15 and December 23 due to year-end internal close. Confirm the cutoff date with your lender or broker early.
What to capture for documentation
Build a small file for each year-end purchase:
- Invoice with purchase date
- Bill of lading or delivery receipt
- Installation completion checklist or photos
- First operational log entry
- Lender funding statement
- Service connection date (electrical, gas, water) if applicable
If the IRS examines the deduction, you want a clear paper trail showing the in-service date.
Common year-end scenarios
Scenario 1: Equipment delivered December 28, operator training starts January 5
Likely qualifies if the equipment is technically operational and you have access to it. Training is improvement, not commissioning.
Scenario 2: Equipment delivered December 28, electrical hookup scheduled January 10
Does NOT qualify. The equipment is not operational without power.
Scenario 3: Truck delivered December 30, awaiting state registration before legal road use
Gray area. The truck is operational but cannot legally perform its business function. Most CPAs treat the registration date as in-service for titled vehicles. Confirm with yours.
Scenario 4: Equipment in transit on December 31, arrives January 2
Does NOT qualify for current year. The deduction shifts to next year.
What you can still do if December slips
Order now, place-in-service early Q1. Locks Q4 manufacturer pricing and dealer availability. Section 179 in the next tax year is still substantial.
Buy in-stock alternates. If your spec’d unit will not arrive in time, dealers often have similar-spec units on the lot that can be modified or accepted as-is.
Look at used inventory. Used equipment qualifies for Section 179 (it must be new to you, not new from the manufacturer). Inventory availability is higher and lead times are shorter.
Consider state-only conformity. Some states recognize accelerated depreciation even when federal timing shifts. Your CPA knows the state rules.
Strategic year-end choices
If you have a strong revenue year, the Section 179 deduction shelters significant income. If you have a weak revenue year, the deduction shelters less and may be better deferred. Talk to your accountant about taxable income projection before committing to a year-end purchase.
Some businesses split a large purchase across two tax years deliberately: half placed in service in December, half in January. This smooths the deduction across years if income is similarly distributed.
The cost of waiting too long
If you are deciding in early December, lender capacity is shrinking. Some lenders shift to higher-credit-only deals as year-end approaches. Approvals that took 24 hours in October may take 5 to 7 days in late December. App-only thresholds may tighten.
If you want year-end timing, the worst time to start is December 15. Start in early November.
Action steps
- Confirm with your CPA whether year-end timing matches your tax position.
- Soft-pull prequalification in early Q4.
- Identify in-stock or short-lead inventory that can be in-service by December 31.
- Set internal deadlines: spec by November 1, signed documents by December 1, delivery and install by December 28.
- Document in-service date the day it happens.
