Montana Has No Sales Tax — Which Has Made It Famous for a Reason Beyond Local Buyers
Montana is one of a handful of states with no general sales tax, and that applies fully to vehicle purchases. There's no state or local percentage-based tax on the purchase price at all — a real and significant savings for Montana residents buying a car.
That zero-tax status has also made Montana well known nationally for a different reason: some out-of-state buyers of high-value vehicles — RVs, exotic cars, boats — form a Montana LLC and register the vehicle in the LLC's name specifically to avoid sales tax in their home state. This is a real and widely reported practice, but it's facing growing legal scrutiny: several states have brought civil and even criminal tax-evasion cases against residents using this structure, and states like Utah and Wyoming have passed legislation specifically targeting it. This is general information, not tax or legal advice — anyone considering this approach should consult a tax attorney familiar with their home state's rules.
For Montana residents simply buying a car to drive in Montana, none of that complexity applies — you just pay registration and title fees with no sales tax layered on top, and no LLC needed.

|---|---|---|
| Sales Tax | 0% | Montana has no state or local sales tax on vehicles |
| Title Fee | $20 | One-time fee to transfer ownership |

| Plate Fee | $10 | Added to registration |
| County Motor Vehicle Tax | Varies by county | 45 of Montana's 56 counties levy a separate local option tax based on depreciated MSRP |

Why Montana Registration Costs Vary by County
While the state portion of Montana's registration fee is flat and age-based (not tied to the vehicle's value), 45 of the state's 56 counties impose their own local option motor vehicle tax on top, calculated as a percentage of the vehicle's depreciated manufacturer's suggested retail price.
This creates real cost variation depending on which county you register in — a newer, higher-value vehicle in a county that levies this tax will cost meaningfully more at registration than the same vehicle in one of the 11 counties that don't.
Because this tax is set at the county level and depends on the vehicle's original MSRP and age, the only way to get an exact figure is to check with your specific county treasurer's office before registering.
