Section 179 in 2026: higher limits and the profit test

For tax years beginning in 2026, the Section 179 dollar limit is $2,560,000. The limit begins to decrease when the total cost of Section 179 property placed in service during the year exceeds $4,090,000. These are the 2026 inflation-adjusted amounts in Revenue Procedure 2025-32, section 4.24.

For most small businesses, the practical question is not whether they can reach the maximum. It is whether a particular purchase qualifies, when it is placed in service, and how much deduction their business income supports.

Three checks before making an election

First, identify eligible property and its business use. A purchase does not qualify simply because it appears on a business credit-card statement. Mixed personal use, certain vehicles and real property require additional analysis.

Second, establish when the property was placed in service. This generally means it was ready and available for its intended business use. A deposit on equipment that will not be operational until the following year does not establish current-year use.

Third, calculate the business-income limitation. Section 179 is generally subject to a taxable-income limit from actively conducted trades or businesses. Amounts limited by that rule may carry forward. Partnerships and S corporations can involve both entity-level and owner-level limitations. The IRS explains the mechanics in Publication 946; its 2025 examples should not be mistaken for 2026 dollar limits.

An illustration of the spending phaseout

Assume a business places $4,190,000 of qualifying Section 179 property in service in a tax year beginning in 2026. That is $100,000 above the $4,090,000 phaseout threshold, reducing the maximum dollar limit from $2,560,000 to $2,460,000 before other limits.

This example explains the phaseout only. It does not establish that the business can deduct $2,460,000, because eligible cost, business income and other restrictions still matter.

Vehicles need a separate check

For 2026, the Section 179 cap for certain sport utility vehicles is $32,000. That is a specific Section 179 restriction, not a statement that every vehicle receives that deduction or that total depreciation always stops there. Vehicle classification, use and other depreciation provisions must be reviewed together.

Make the purchase decision with cash flow in view

A deduction reduces taxable income; it does not reimburse the full purchase price. Compare the operational need, financing cost, available cash and expected tax effect before committing to equipment.

Gather the invoice, purchase agreement, financing documents, installation or delivery records, business-use evidence and current asset schedule. Then compare Section 179 with other permitted depreciation treatment as part of a complete tax projection.
