    Wyoming's state sales tax rate is 4%, which comes to $1,000.00 on a $25,000 purchase with no trade-in.

    Counties add their own local option sales tax on top, commonly 1% to 2%, so your combined rate depends on where you register the vehicle.

    The taxable price is the purchase price less the trade-in allowance and any rebate, so both reduce what you owe.

    Wyoming Car Title and Registration Fees

    Wyoming's title fee is $15. Registration combines a $30 state fee with a county fee based on the vehicle's factory price and age, so we have not added a single flat registration figure; enter your own amount under Advanced options.

    How Wyoming Car Sales Tax Is Calculated

    1. Start with the purchase price.
    2. Subtract your trade-in allowance and any rebate.
    3. Multiply the result by the state rate of 4%.
    4. Add your county's sales tax rate for where you register the vehicle.
    5. Add the $15 title fee, the $30 state registration fee, and your county's age-based registration fee to reach your out-the-door price.

    Wyoming's county registration fee formula multiplies the vehicle's original factory price by a percentage that starts at 60% in the first year of service and steps down to 15% by the sixth year and after, then applies a 3% rate to that figure.

    Wyoming's county registration fee is calculated from the vehicle's original factory price and how many years it's been registered, so it's worth asking your county treasurer for an estimate. Read how a trade-in affects sales tax to see how Wyoming compares with other states.
