Section 179
For tax year 2027, a business can expense up to $2,640,000 of section 179 property, up from $2,560,000 for 2026. The section 179 limit for sport utility vehicles is $33,100. Revenue Procedure 2026-35 adds the phase-out: the $2,640,000 limit is reduced, dollar for dollar but not below zero, by the amount by which the cost of section 179 property placed in service in 2027 exceeds $4,230,000.
