For the 2026 tax year, Section 179 generally applies to qualifying business equipment placed in service by December 31 — ready and available for use, not merely ordered or financed. IRS Publication 946 and 26 U.S.C. § 179 define the rules; talk to your tax professional before you buy or elect a deduction.
Confirm timing and eligibility with your CPA.
What “placed in service by Dec 31” means
Section 179 is tied to the tax year property is placed in service — when it is ready and available for use in your business, not when you sign a quote or receive lender approval. IRS Publication 946 describes placed-in-service rules for depreciable property. The statute is 26 U.S.C. § 179; the IRS also publishes a Section 179 deduction overview for equipment.
Common year-end situations
Equipment delivered, installed, and ready for business use before Dec 31
Often yes — if it meets IRS qualifying property rules and your CPA agrees
Ordered and financed, but not delivered or not ready for use by Dec 31
Generally no for that tax year — placed in service timing drives the year
Deposit paid; lender approved; machine still in transit
Generally no until the asset is ready and available for use in the business
FMV operating lease (lessor owns the equipment)
Section 179 usually does not apply to the lessee — see financed-equipment guide
Financing, delivery, and tax planning
Equipment financing can help you acquire machinery, but tax treatment follows ownership and placed-in-service facts — not how fast an inquiry moves. Submitting a financing inquiry does not place equipment in service. If you are comparing loan vs lease structures before year-end, read Section 179 on financed or leased equipment and model deductions in the Section 179 calculator (2026) using your CPA's assumptions.
Dollar limits, phase-outs, and income caps change by tax year. Confirm the figures that apply to you in Publication 946 rather than relying on marketing copy or third-party summaries.
Records that support your CPA’s work
- Invoice or bill of sale with cost and description
- Proof of delivery and the date the asset was ready for business use
- Financing or lease agreement showing who owns the equipment for tax purposes
- Business-use documentation supporting more than 50% business use when required

Common questions
- Does Section 179 use the date I pay for equipment or the date I finance it?
- Neither date alone controls the tax year. IRS rules focus on when qualifying property is placed in service — ready and available for use in your trade or business. Publication 946 explains placed-in-service timing for depreciable property. Talk to your tax professional about your facts.
- If I submit a financing inquiry in December, does that count for Section 179?
- No. A financing inquiry or approval is not the same as owning and placing equipment in service. Section 179 follows federal tax rules on property use and ownership, not the date you submit a financing inquiry.
- Can financed equipment still qualify if it is placed in service by Dec 31?
- Often yes when your business is treated as the owner and the asset is qualifying property under 26 U.S.C. § 179. Owing a lender does not by itself remove eligibility. Capital leases treated as purchases may qualify; FMV operating leases generally do not. See our guide on financed and leased equipment for structure basics.
- Where should I confirm dollar limits and phase-out rules?
- Use IRS Publication 946 and the IRS Section 179 deduction overview for the tax year you are filing. Limits and phase-outs change; your CPA applies them on your return. This guide does not state current dollar caps.
