Selling or buying a used vehicle in Montana? A bill of sale is your proof of the deal - it records who sold what, for how much, and on what date. Montana transfers ownership through the assigned title and an Application for Certificate of Title (Form MV1), and a bill of sale (Form MV24) is used alongside it: it locks in the price, the exact handover date, and the fact that the seller is no longer responsible for tickets or accidents once the keys change hands.
State rules
Montana requirements
The rules people ask about most, answered for Montana.
Is a bill of sale required in Montana?
Often, yes. Ownership transfers through the assigned title and Form MV1 at your county treasurer's office, and a bill of sale (Form MV24) is commonly required alongside it to document the price, VIN, and date of sale. It also proves you're no longer liable for the vehicle.
Does it need to be notarized?
No. As of October 1, 2025, Montana no longer requires titles to be notarized for individuals or businesses. A notarized bill of sale may still be needed in special cases - such as a bonded title or a transfer by power of attorney - but a routine private sale does not require notarization.
Title transfer deadline
The buyer has 40 days from the date of sale to apply for the title and register the vehicle at the county treasurer's office in their county of residence. Wait longer than 40 days and a $10 late fee applies.
Motor vehicle sales tax
Montana has no general state sales tax, so private-party used vehicle sales are not subject to sales or use tax. The buyer still pays title and registration fees at the county treasurer's office.
Odometer disclosure
Federal law requires the odometer reading at the time of sale for vehicles under 20 model years old. Record it on both the bill of sale and the title.
Rules change. Confirm the current requirements with your county treasurer's office (Montana MVD) before you sign.

Common questions
Montana bill of sale FAQ
Does a Montana motor vehicle bill of sale need to be notarized?
No. As of October 1, 2025, Montana no longer requires titles to be notarized, and a routine private-party bill of sale doesn't need notarization either. It's only required in special cases like a bonded title or a transfer under power of attorney.
Do I need a bill of sale to sell a car in Montana?
Usually yes - Montana commonly requires a bill of sale (Form MV24) alongside the assigned title and Form MV1 to document the price, VIN, and sale date. It also proves you're no longer responsible for the vehicle after the sale.
Where do I transfer the title in Montana?
At the county treasurer's office in your county of residence, which handles titling and registration for the Montana Motor Vehicle Division. The buyer brings the assigned title, a completed Form MV1, the bill of sale, and payment for the title and registration fees.
How long do I have to transfer the title in Montana?
The buyer has 40 days from the date of sale to apply for the title and register the vehicle at the county treasurer's office. Wait longer than 40 days and a $10 late fee applies, so don't wait.
How much is sales tax on a used car in Montana?
There's no general state sales tax in Montana, so private-party used vehicle sales aren't taxed. The buyer still pays title and registration fees at the county treasurer's office when transferring ownership.
Do both the buyer and seller need to sign?
Yes. Both parties should sign and date the bill of sale, and each keeps a copy. If there are two buyers or two sellers, every party signs.
Is a handwritten bill of sale valid in Montana?
Yes - a handwritten bill of sale is valid as long as it has the key details, though the state's Form MV24 is the standard. A complete, typed document like this one is simply cleaner and far less likely to be questioned at the county treasurer's office.
