Calculate first-year write-offs, heavy vehicle exemptions, and cash tax reduction
Section 179 Estimator is a free resource built to help small business owners, freelancers, and self-employed professionals understand one of the most valuable — and most misunderstood — tax provisions available to them: the Section 179 deduction for business vehicles and equipment.
The tax code around vehicle depreciation is dense. Between Section 179 expensing, bonus depreciation, luxury auto limits, heavy SUV caps, and state-by-state conformity differences, it's easy to leave money on the table — or claim something incorrectly. This site exists to make those rules accessible through interactive calculators and plain-English guides.
Every calculator and guide on this site is maintained and updated for the current tax year. When IRS limits change, when bonus depreciation phases shift, or when states update their conformity rules, the content here is revised to reflect it. Accuracy matters — these numbers affect real purchasing decisions.
That said, this site is an educational planning tool, not a substitute for professional tax advice. Tax situations vary, and the figures here are estimates. Always confirm your specific situation with a qualified CPA or tax attorney before filing.
