Registration by age

Montana's registration rate depends only on age, figured by subtracting the model year from the year the fee is due. A new car pays the top $217 rate for its first years, which is why the calculator's total for a new car is mostly registration.

Light vehicles 11 years or older can be registered permanently and don't need renewing while you own them. Permanent registration costs more upfront, including five times the local option tax or flat fee.
