Section 179 of the IRS code lets a business deduct the full purchase price of qualifying equipment in the year it is placed in service, rather than depreciating it over multiple years. For 2026, the Section 179 deduction limit is $1,220,000 with a phase-out starting at $3,050,000 of qualifying equipment purchases.
What qualifies
Most tangible business equipment qualifies: trucks, machinery, computers, off-the-shelf software, and even certain improvements to non-residential buildings. The equipment must be used more than 50% for business and placed in service before the end of the tax year.
Section 179 vs bonus depreciation
Section 179 is taken first. After §179 caps out, the remainder can be depreciated using bonus depreciation (60% in 2026, phasing down further in subsequent years). What is left after both goes into standard MACRS depreciation.
Income limitation
The §179 deduction cannot exceed your business taxable income for the year. If equipment cost exceeds income, the unused portion carries forward to future tax years.
Financing and §179
You do not need to pay cash to claim §179. Financed equipment qualifies in the year placed in service, even if you only made a small down payment. This is one reason financing-to-own is often more tax-efficient than leasing for businesses with §179 capacity. See our full Section 179 guide.
