How Michigan taxes a car deal
- State tax rate
- 6%
- Local add-ons
- None typical
- Trade-in credit
- Yes — first $12,000 of trade
- Doc fee
- Capped at $280
Michigan taxes vehicles at a flat 6% with no local add-ons — simple, except for one rule that matters more here than anywhere: the trade-in credit is capped. For 2026, only the first $12,000 of your trade-in value reduces the taxable price. Trade in a $20,000 truck and the last $8,000 of it still gets taxed as if it weren't there — $480 in tax a buyer in a full-credit state wouldn't pay. Our calculator applies the cap automatically; most generic ones don't.
The cap is on a schedule worth knowing if your purchase timing is flexible: it rises $1,000 every January 1 — $13,000 in 2027, $14,000 in 2028 — and disappears entirely in 2029, when Michigan joins the full-credit states. If you're trading a high-value vehicle in late December, a few weeks' patience is literally worth $60 in tax per thousand dollars of trade value above the current cap.
Two exclusions catch people: leases don't qualify for the trade-in credit at all (lease deals run under use tax, a different regime), and neither do private-party purchases — the credit exists only on dealer sales. Michigan also caps dealer doc fees at the lesser of $280 or 5% of the price, keeping that line modest by national standards.
Every figure above was last verified against official Michigan sources in August 2026. Tax rules do change — the final word is always your paperwork and the DMV.
