Wyoming Vehicle Registration Fee Calculator

Wyoming splits registration between a small state fee and a much larger county fee, and almost every surprise in a Wyoming bill comes from the second one. The state charges a flat $30.00 for a passenger car. The county charges the greater of $5.00 or 3% of the vehicle's ORIGINAL FACTORY PRICE multiplied by an age factor: 60% in the first year of service, then 50%, 40%, 30% and 20%, settling at 15% from the sixth year onward (Wyo. Stat. §31-3-101(b)). On a $32,000 car that is roughly $576 in year one against the state's $30 — so quoting "$30 to register in Wyoming" understates a new-car bill by about twenty times. Note the base is the original factory price, so buying that car used does not reduce it; only age does. There is one genuinely counterintuitive rule worth stating plainly: §31-3-101 says these registration fees are "in lieu of taxes upon vehicles as provided by W.S. 39-13-103(b)(i)" — that means they replace the vehicle PROPERTY tax, NOT sales tax. Wyoming still charges its ordinary 4% state sales tax on the purchase (§39-15-104(a)(i)(A)) plus a county rate, giving combined totals from 4% in Park and Sublette counties up to 7% in Teton, and 9% inside the Teton Village and Grand Targhee resort districts. Reading "in lieu" as "no sales tax" would be an expensive mistake. A trade-in does reduce the taxable amount, but Wyoming requires the trade-in vehicle's title to already be in the purchaser's name. Title is $15.00; all-electric vehicles pay a $100 annual decal and plug-in hybrids $50.
