Montana Dealer Doc Fee Cap, Registration & Hidden Fee Statutory Guide (2026)
Updated October 28, 2026: Before signing a buyer's order in Montana, separate mandatory state government fees (title, registration, plate, and statutory sales/excise tax) from negotiable dealer-pocketed fees and optional F&I add-ons:
- 2026 Montana Dealer Doc Fee Limit: No state dollar limit found (No state dollar limit found in our check (Montana imposes 0% state sales tax on vehicles, so a dealer doc fee is not taxed). Dealers set the fee; ask for it in writing with the out-the-door price. Controlling authority: Montana Motor Vehicle Division — Title & Registration (no state statutory dollar cap; verified Oct. 28, 2026)).
- Is the Dealer Doc Fee Taxed in Montana? Not taxed when separately stated on the buyer's order (Montana Motor Vehicle Division — Title & Registration: Montana imposes 0% state sales tax on vehicles, so a dealer doc fee is not taxed).
- Government Title & Registration vs. Dealer Add-Ons: Government title and registration fees go directly to the Montana DMV/revenue agency and must be itemized separately. Pre-printed dealer add-ons (nitrogen tires, VIN etching, ceramic coating, LoJack/GPS trackers, dealer prep, or reconditioning fees) are optional dealer profit items—not state-mandated fees.
