Overview
The real headline is what happens after year 11: instead of paying $28 every year forever, you can pay a one-time $87.50 permanent registration fee (plus five times your county's option tax) and never see a renewal notice again for as long as you own the vehicle. Electric and plug-in hybrid vehicles add a separate weight-based surcharge on top of all of this. The calculator below covers every combination.

How Montana registration works, step by step
- 1
Check your vehicle's age: subtract the model year from the current calendar year.

Look up your county's option tax rate - five counties charge none at all.
- 3
If the vehicle is 11+ years old, decide between the annual $28 fee or the one-time permanent option.
- 4
Add the EV or PHEV surcharge if it applies, based on the vehicle's unladen weight class.
- 5
Pay at your county treasurer's office; no inspection of any kind is required first.

Montana registration fees FAQ
How is a vehicle's 'age' determined for Montana registration?
By subtracting the model year from the calendar year the registration covers - a 2023 model registered in 2026 is 3 years old (0-4 tier, $217), not counted from the purchase date.
Is the permanent registration option worth it?
Almost always, if you plan to keep the vehicle. $87.50 plus 5× your county's option tax replaces every future $28 annual fee for as long as you own the car - for most owners that pays for itself in under five years and then registration is simply done.
Do EVs and hybrids pay the age-based fee too?
Yes - the EV/PHEV charge stacks on top of the normal age-based registration fee, it doesn't replace it. A 3-year-old Class 1 EV owes $217 (age fee) + $130 (EV fee) = $347, before any county tax.
What are the EV weight classes and their fees?
Class 1 (under 6,000 lbs, nearly all passenger EVs): $130/yr. Class 2 (6,000-10,000 lbs): $190/yr. Class 3 (10,000-26,000 lbs): $340/yr. Class 4 (over 26,000 lbs): $1,100/yr. Plug-in hybrids pay roughly half those amounts per class.
Can I get a permanent EV registration too?
Yes, for Class 1 and 2 EVs: a one-time $260 (Class 1) or $380 (Class 2) fee replaces the annual EV surcharge permanently, paid alongside the standard $87.50 permanent light-vehicle fee once the vehicle turns 11.
Which counties charge no option tax at all?
Big Horn, Deer Lodge, Flathead, Granite, and Richland counties currently impose no local option motor vehicle tax - registering the identical vehicle there costs less than in a county at the 0.5-0.7% rate.
