How each state structures it
South Dakota
South Dakota has one of the lower vehicle tax burdens in the US: a 4% Motor Vehicle Excise Tax replaces sales tax (no local additions), full trade-in credit, no annual ad valorem, no state income tax, and no required inspections or emissions testing. Registration is weight + age tiered ($72/year for typical passenger; 30% discount for vehicles 10+ years old). Title fee is just $10. County wheel tax can add up to $60/vehicle in participating counties. EV surcharge is $50/year (low by US standards). A new $35,000 vehicle in South Dakota runs about $1,503 in first-year costs (mostly the $1,400 excise tax + $76 registration + small fees), with annual renewals around $76.
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+.
