Michigan charges 6% sales tax on a private car sale, collected by the Secretary of State when you transfer the title. On a private-party purchase, that 6% is applied to whichever is higher: the price you actually paid or the vehicle’s retail dollar value in the state’s pricing guide. So if you paid $3,000 for a car the state values at $8,000, your tax bill is built on the $8,000 figure.1Michigan Department of Treasury. RAB 2017-26 Vehicle Transfer Tax Base
Why the State Can Tax More Than You Paid
Two different Michigan tax laws apply to vehicle transfers. Buying from a licensed dealer triggers use tax on the actual purchase price, the way sales tax works at any store. Buying from a private seller, or receiving a vehicle from anyone who isn’t a licensed dealer, triggers the Streamlined Sales and Use Tax Revenue Equalization Act. Under that law the 6% rate applies to the vehicle’s “retail dollar value” at the time of transfer, as determined by the Department of Treasury.1Michigan Department of Treasury. RAB 2017-26 Vehicle Transfer Tax Base
Treasury uses the National Automobile Dealers Association (NADA) valuation guide as the benchmark. Michigan Administrative Code Rule 205.135 sets the floor at the “retail dollar value as listed in any recognized guide.”2Michigan Department of Treasury. Transferring a Vehicle Title to a Relative This structure exists to keep buyers and sellers from writing an artificially low price on the title to shrink the tax bill. It covers motor vehicles, motorcycles, off-road vehicles, snowmobiles, and watercraft.3Michigan Department of Treasury. Use Tax
If Michigan use tax was already paid on the same vehicle at some earlier point, you can claim a credit against the equalization tax, up to the amount of equalization tax owed.1Michigan Department of Treasury. RAB 2017-26 Vehicle Transfer Tax Base
Challenging the NADA Value
You are not stuck with the guide’s number if the car is genuinely worth less. Treasury will consider several kinds of evidence, and none of them is automatically decisive:
- A written retail value appraisal from a licensed dealer or repair shop that identifies the vehicle by VIN and reflects its condition at the time of transfer.
- Repair receipts (for work done after the transfer date) or repair estimates (from any date), from a licensed dealer or shop.
- A seller-signed bill of sale stating the price and describing the vehicle’s condition in a way that explains the lower value.
- A valuation from another industry-accepted pricing guide such as Kelley Blue Book.
- A written appraisal from an insurance company.
Whatever you bring has to establish the value at the time of transfer, not months later. A repair estimate dated six months after the sale carries little weight unless you can show the damage existed on the day you bought the car.1Michigan Department of Treasury.

Family Transfers That Skip the Tax
MCL 205.93 exempts transfers between certain relatives:
- Spouses
- Parents and children, including stepparents and stepchildren
- Siblings, including stepbrothers and stepsisters
- Grandparents and grandchildren
- Legal wards and legally appointed guardians (the guardian needs a certified letter of guardianship)
Aunts, uncles, cousins, and in-laws are not on that list. A transfer between those relatives is taxed at the standard 6%.4Michigan Legislature. Michigan Compiled Laws 205.93 – Use Tax Act
A separate exemption covers a vehicle passing to a named beneficiary during the administration of an estate, with no relationship requirement.5Michigan Department of Treasury. 4Michigan Legislature. Michigan Compiled Laws 205.93 – Use Tax Act
Credit for Tax Paid to Another State
If you bought the vehicle in another state and paid that state’s sales or use tax before bringing it to Michigan, MCL 205.94 allows a credit when the other state’s rate was equal to or greater than Michigan’s 6% and that state gives Michigan-taxed property the same treatment. Pay a lower rate elsewhere and Michigan collects the difference. A 4% out-of-state tax means Michigan bills you the remaining 2%.6Michigan Legislature. Michigan Compiled Laws 205.94 – Use Tax Act The credit only applies to tax actually paid, so keep the receipt from the other state’s tax authority.
Federal Gift Tax on High-Value Vehicles
Michigan’s 6% is separate from any federal gift tax. If someone gives you a vehicle worth more than $19,000 in 2026, the giver may need to file IRS Form 709. The $19,000 annual exclusion is per recipient per year, so an $18,000 gift doesn’t trigger a filing.7Internal Revenue Service. Gifts and Inheritances 1 The return is the giver’s responsibility, and filing it doesn’t necessarily mean tax is owed because a large lifetime exemption applies.8Internal Revenue Service. Instructions for Form 709
What to Bring to the Secretary of State
Gather these before you start the transfer:
- The signed title, with buyer and seller information, purchase price, and date of sale filled in.
- A bill of sale, signed by the seller, stating the price and describing the condition. This is especially important if you paid less than NADA value or the car needs work.
- Proof of the qualifying relationship if you’re claiming the family exemption. Guardians need a certified letter of guardianship.
- A valid Michigan driver’s license or state ID.
- Proof of Michigan no-fault insurance, required before registration.
Make sure the VIN and mileage match across every document. Mismatches cause delays and can prompt a valuation dispute.
Simple one-buyer, one-seller transfers can be processed online through the Secretary of State’s website. More complex transactions require an office visit, which averages about 20 minutes. Mail and self-service stations aren’t options for title transfers.9Michigan Secretary of State. Title Transfer and Vehicle Registration The state accepts cash, personal checks, and major credit or debit cards. Beyond the 6% tax, expect a $15 title fee and a plate fee ($5 for a standard plate or $10 to transfer an existing plate).10Michigan Secretary of State. License Plates and Tabs
The 15-Day Deadline
You have 15 days from the date of sale to transfer the title. Miss the window and the Secretary of State tacks on a $15 late fee.9Michigan Secretary of State. Title Transfer and Vehicle Registration Driving on an untransferred title also creates insurance and liability problems that cost far more than the late fee to untangle. Once the clerk checks your paperwork and takes the tax payment, you’ll get a temporary registration, and the permanent title comes by mail.
