Free Montana Motorcycle Bill of Sale
What you negotiate is what you pay in Montana — the state has no sales tax, so a motorcycle purchase carries zero tax whether it's a $1,500 dirt bike or a $30,000 tourer. The transfer itself runs through the county treasurer in the buyer's home county: the MV1 title application plus the seller-signed title, filed within Montana's roomy 40-day window, with only title and registration fees due at the counter. There's no inspection for a Montana-to-Montana sale; a bike arriving from out of state may need a VIN check before titling. The bill of sale earns its keep here as the record of price and date — not for a tax office, but for the ownership chain.

Sales Tax Details
No sales tax in Montana — applies to motorcycles too.
Montana Motorcycle Sale — Step-by-Step Checklist
- Verify the frame VIN against the Montana title before paying.
- Complete the MV24 bill of sale with VIN, year, make, model, odometer, price, date, and both signatures.
- Seller signs the title over with the odometer disclosure.
- Buyer files at the county treasurer of their home county within 40 days.
- Buyer pays title and registration fees only — Montana collects no tax on the purchase.
- Bike coming from another state? Plan for a VIN verification before the treasurer issues the Montana title.
- Buyer: hold Montana's motorcycle endorsement before riding.
Common Pitfalls
- Waiting for a tax bill that never comes — and therefore skimping on the bill of sale; with no tax filing, that document is the deal's primary record.
- Treating the 40 days as infinite — Montana's window is generous, but late-title penalties exist and start on day 41.
- Going to an MVD office — Montana vehicle transfers happen at the county treasurer.
- Forgetting the out-of-state VIN check — a bike with non-Montana paperwork needs verification before titling.
