Free Montana Trailer Bill of Sale
A Montana trailer purchase is a one-visit, one-cost affair: zero sales tax on the price, the MV1 title application plus the seller-signed title at the county treasurer within 40 days — and for qualifying light trailers, registration under the same one-time PERMANENT scheme (MCA 61-3-321) that covers Montana's boats: pay once, never renew. That combination — no tax at purchase, no recurring registration on permanent-class trailers — makes the lifetime paperwork cost of a Montana utility trailer nearly zero after the first courthouse visit. The bill of sale still earns its place as the record of price and date in a state that never taxes the transaction.

Sales Tax Details
No sales tax in Montana — trailer sales are also tax-free.
Montana Trailer Sale — Step-by-Step Checklist
- Verify the VIN or serial plate on the tongue against the Montana title.
- Complete the MV24 bill of sale with VIN/serial, type, weight, sale price, date, and both signatures.
- Seller signs the title over.
- Buyer files at the county treasurer of their home county within 40 days.
- Buyer pays title and registration fees only — Montana charges no sales tax.
- Ask about permanent registration — qualifying trailers register once under MCA 61-3-321 and never renew.
- No inspection applies to Montana trailer transfers.
Common Pitfalls
- Budgeting annual renewals on a permanent-class trailer — one payment at the treasurer can cover the trailer's lifetime.
- Looking for an MVD branch — Montana trailer titles and registration run through the county treasurer.
- Treating the 40-day window as decoration — late-title penalties exist despite the generous margin.
- Skipping the bill of sale because no tax is due — it remains the only record of what was paid and when.
Pro Tip
Montana trailers: the MV24 bill of sale, MV1 title application, and the signed title at the county treasurer within 40 days, zero tax at purchase — and for qualifying trailers, one permanent registration that outlasts the paperwork of every neighboring state.
