Wyoming Vehicle Registration Cost

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+.

How Wyoming calculates registration

• State Registration Fee — $30 (annual) Per Wyoming Statutes Title 31. Flat state fee for passenger vehicles. Heavy trucks have weight-based fees. State fee goes to WYDOT.
• County Fee (MSRP × year-of-service × 3%) — 3% of depreciated value (annual) Per Wyoming Statutes §39-13-104. Wyoming's County Fee is an ad valorem personal property tax that varies by vehicle age but NOT by county — formula is uniform statewide: Factory Cost (original MSRP) × Year of Service Rate × 3%. The year-of-service rates step down: 60% (year 1), 50% (year 2), 40% (year 3), 30% (year 4), 20% (year 5), then 15% from year 6 onward. For a $35K new vehicle, year 1 County Fee is $630, dropping to $158 by year 6+. This is tax-deductible as personal property tax on federal returns.
• Title Fee — $15 (one-time) One-time title fee per Wyoming DOT fee schedule.

Sales tax

Wyoming charges 4% state sales tax , with typical local rates around 1.5% (range: 0%–2%). Trade-in credit: full. Tax basis: purchase price.

Wyoming charges 4% state sales tax with local additions ranging 0-2% (most counties 1-2%). Combined rates: Cheyenne (Laramie County) 6%, Casper (Natrona County) 5%, Jackson (Teton County) 6%. Sales tax is collected by the county clerk at registration based on the registering county's rate (not the dealer location). Trade-in is fully credited.

Electric vehicle surcharge

Wyoming charges an additional $100/year for electric vehicles.

Per Wyoming HB 145 of 2026 (signed March 2026). Effective July 1, 2026, the annual all-electric vehicle decal fee was REDUCED from $200 to $100. A NEW $50/year plug-in hybrid electric vehicle decal fee was also enacted. The bill also exempts alternative fuels (electricity) for vehicles from sales tax and exempts Level 2 chargers from alternative fuel tax. The reduction was made because EV owners were considered "triple-taxed" (decal + alternative fuel tax + sales tax on electricity). Multipurpose electric vehicles and electric motorcycles are exempt.

What makes Wyoming distinctive

• Wyoming's County Fee at 3% × MSRP × year-of-service is a depreciating annual tax — meaningful in year 1 ($630 on a $35K vehicle) but drops to just $158 by year 6+. Combined with low or no income tax in Wyoming, total state and local tax burden remains low overall, but vehicle ownership in early years is moderate-to-high.
• Wyoming uses ORIGINAL FACTORY MSRP for the County Fee — not what you paid. Buying a used $15K vehicle that had $40K MSRP means paying County Fee on the $40K figure (depreciated for age). The MSRP is captured at first WY registration.
• Wyoming registration fees are UNIFORM STATEWIDE per state statute — every Wyoming county charges the same County Fee formula and state fee. Only sales tax rates vary by county. This is unusual; most states with county-based vehicle taxes have rate variation.
• Wyoming's $200/year EV surcharge is tied for among the highest in the US (matching Texas, Ohio, Oklahoma). Plus EVs still owe the full County Fee (since it's based on MSRP, not fuel type). For a $50K EV, total year-1 cost is around $2,500+ — making Wyoming expensive for EV adoption despite no income tax.
• Wyoming does NOT require vehicle inspections or emissions testing — eliminated entirely. Combined with no state income tax (one of only nine such states), Wyoming has a unique tax profile: low income/sales tax, but moderate ongoing vehicle ownership costs via the County Fee.
