The short answer for Michigan buyers
Michigan vehicle sales and use tax is 6% statewide, with no local vehicle-sales-tax add-on. Dealer and private-party transactions use different tax bases, and the 2026 qualifying dealer trade-in deduction is capped at $12,000.
How this Michigan estimate is calculated
For dealer sales, start with taxable selling price and supported taxable additions/rebates, subtract dealer discounts and the eligible trade allowance, then apply 6%. For ordinary private-party transfers, tax uses the greater of purchase price or retail/fair-market value; the dealer trade credit is unavailable.
Worked example from the live calculation engine
Example from the sales-tax engine: a $32,000 dealer vehicle plus $280 taxable documentation, less a $12,000 allowed portion of a $15,000 trade, leaves a $20,280.00 base. At 6%, estimated tax is $1,216.80. The $7,000 payoff does not change the tax deduction.
Common Michigan estimate mistakes
- Assuming all of a trade worth more than $12,000 is deductible in 2026.
- Subtracting loan payoff from the tax allowance instead of separating trade equity.
- Using a county sales-tax rate for a vehicle purchase or using purchase price alone for every private sale.

Michigan car sales tax questions
What is Michigan's car sales tax rate?
Michigan's state sales/use tax rate is 6%. Local governments do not add a separate vehicle sales-tax rate.
Is used-car tax different from new-car tax?
The 6% rate is the same. Dealer sales use the dealer transaction's taxable price; an ordinary private-party transfer uses the greater of purchase price or the supported retail/fair-market value.
Does a Michigan trade-in reduce sales tax?
A qualifying trade accepted by a dealer can reduce the taxable base. For 2026, the deduction is capped at $12,000 and cannot exceed the taxable amount.
Does my trade loan payoff reduce the tax deduction?
No. The separately stated trade allowance is the tax figure. Payoff changes your trade equity, not the deductible allowance.
Can I deduct a trade-in on a private-party purchase?
The ordinary private-party path does not receive the dealer trade-in deduction. Use the private-sale value basis and confirm special exchanges with Treasury or SOS.
Are dealer fees taxable in Michigan?
Tax treatment depends on what a charge represents. Documentary preparation is taxable under the supported dealer guidance; ask the dealer to identify each line rather than treating all charges alike.
