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 $560 higher. Arizona gives a trade-in credit, so a $10,000 trade cuts state tax on a $30,000 car from $1,680 to $1,120. If a private buyer would pay more than $10,000 + $560, selling privately comes out ahead.
The math:
- $30,000 car, no trade-in: $1,680 state tax at 5.6%
- $30,000 car, $10,000 trade-in: $1,120 state tax (trade-in rule: allowed)
- Local county/city tax adds to both; enter yours above.
