How each state structures it
Montana
Montana is one of only FIVE US states with no general sales tax — making vehicle purchases tax-free regardless of price. Age-tiered registration is $217/year for new vehicles (0-4 years old), dropping to $87 (5-10 years) and $28 (11+ years). 45 of Montana's 56 counties impose a 0.5% county option tax on depreciated MSRP — about $175/year for a $35,000 new vehicle. A "luxury surcharge" of $825/year applies to vehicles with MSRP over $150,000 that are 10 years old or less. Title fee is $10 + $10 Highway Patrol fee. Montana has no EV surcharge. A new $35,000 vehicle in Montana (participating county) runs about $412 in first-year costs — among the lowest in the US (the no-sales-tax savings is $2,100+ vs neighbors). Annual renewals around $392.
Wyoming
Wyoming has substantial annual vehicle costs driven by the County Fee — an ad valorem tax of 3% applied to MSRP × year-of-service rate (60% year 1, dropping to 15% by year 6+). For a $35,000 new vehicle, year 1 County Fee is $630, declining to $158 by year 6+. Combined with the flat $30 state fee and 4% state sales tax (plus typical 1-2% local), Wyoming sits among the higher-cost states for new vehicle ownership but cheaper for older ones. EV surcharge is among the highest in the US at $200/year. A new $35,000 vehicle in a typical Wyoming county runs about $2,575 in first-year costs, with annual renewals around $660 in year 1 dropping to ~$200 by year 6+.
What this means for you
- Buying a new car: Montana is roughly $2,188 cheaper than Wyoming in the first year on a $35K vehicle, driven mostly by sales tax and one-time fees.
- Annual renewal: Montana is cheaper to renew annually by about $170/year. Over a 5-year ownership period that's roughly $850 in renewal-fee savings alone.
- If you drive an EV: Wyoming's EV surcharge ($100/year) is meaningfully lower than Montana's ($130/year) — a 23% savings on the EV fee alone.
- Structural differences: Wyoming charges an annual ad valorem property tax on vehicles (renewals stay expensive as long as you own the car), while Montana does not — over a 10-year hold this can swing thousands of dollars toward Montana.
