These are the rules for a new car bought from a dealer. Used-car and private-sale rules can differ. How we check this data.
Wyoming charges 4% at the state level. Local taxes add more. That rate is higher than 7 states and lower than 39 states. County and city taxes may add to it, so check your local rate and enter the total in the calculator.
What to know in Wyoming
Wyoming's 4% state rate is joined by county taxes in most counties, so the combined rate is higher. Check your county's rate and enter the total in the calculator.
The trade-in is deducted from the price before the tax is figured, as long as it's titled in your name. If your old car is titled to someone else, such as a family member, sort out the title before you trade it in.
Does Wyoming tax your trade-in?
No. Wyoming only taxes the difference between the new car's price and your trade-in. On a $35,000 car with a $10,000 trade-in, you'd pay $1,000.00 in state tax instead of $1,400.00, a saving of $400.00. That saving is worth counting when you compare a dealer's trade-in offer with selling the car yourself.
Example: a car loan in Wyoming
A $35,000 car with $5,000 down, $1,500 in fees, and a 60-month loan at 6.5% APR ($1,400.00 state tax, rolled into the loan):
- Monthly payment: $643.73
- Amount financed: $32,900
- Total interest: $5,724
- Total cost of the car: $43,624

Rebates and fees
The calculator charges tax on the price before any manufacturer rebate. Ask the dealer how Wyoming treats your specific rebate. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
