Manufacturer rebates in Wyoming
Rebate comes off before tax
Taxable = sales price minus trade-in minus a manufacturer rebate assigned to the dealer.
Example math: $1,000 rebate × 4.0% (state rate, as of Oct 2026) = about $40 less state tax (estimate; state rate only, local tax not included).

Best pick for your situation
If you have a car to sell: trade it in at the dealer when the private-sale price is less than $400 higher. Wyoming gives a trade-in credit, so a $10,000 trade cuts state tax on a $30,000 car from $1,200 to $800. If a private buyer would pay more than $10,000 + $400, selling privately comes out ahead.
The math:
- $30,000 car, no trade-in: $1,200 state tax at 4%
- $30,000 car, $10,000 trade-in: $800 state tax (trade-in rule: allowed)
- Local county/city tax adds to both; enter yours above.
