Common Questions
Over-the-road tractor units are classified as 3-year MACRS property under IRS Asset Class 00.26. Using the standard half-year convention, you deduct 33.33% in year 1, 44.45% in year 2, 14.81% in year 3, and 7.41% in year 4.
Yes. Over-the-road tractors qualify for Section 179 expensing up to the annual limit ($1,160,000 for 2023). You can also use bonus depreciation (100% for property placed in service through 2022, phasing down after). Combining Section 179 and bonus depreciation can allow full first-year deduction.
Yes. The Tax Cuts and Jobs Act of 2017 expanded bonus depreciation to include used property. A used tractor qualifies as long as it is new to you (you have not previously used it) and was not acquired from a related party.
Tax disclaimer: This calculator provides estimates based on standard IRS MACRS rules from Publication 946. Your actual depreciation deduction may differ based on business-use percentage, the mid-quarter convention, state tax conformity, bonus depreciation phase-outs, and other factors specific to your situation.
