Does a trade-in reduce sales tax in Michigan? Yes — here's how much

How Michigan treats a trade-in

Michigan subtracts your trade-in from the price before tax, but caps the credit at $12,000.00. A trade worth more than that only reduces your taxable amount by the capped figure.
In numbers: at Michigan's 6%, a $10,000 trade-in saves you $600.00 in tax.

Rebates are a separate question

Manufacturer rebates are treated differently from trade-ins here: tax is calculated BEFORE the rebate comes off, so you pay tax on money you never kept.
A dealer's own discount does reduce the taxable amount. That distinction between a dealer discount and a factory rebate is worth understanding before you negotiate.

What's specific to Michigan

Your trade-in reduces the taxable amount, but Michigan caps the credit at $12,000 for 2026 (the cap has risen $1,000 each January since 2019 and becomes unlimited starting January 1, 2029).
Manufacturer rebates are taxed in Michigan: tax is computed on the price before the rebate. A dealer's own cash discount, by contrast, does lower your taxable price.

Some dealers now fold fees into the advertised price (FTC pressure; California's total-price law). Check what yours covers so nothing gets counted twice.
