California Car Sales Tax Calculator
Accurate 2026 Calculations with County-Specific Rates
1 Understanding California Car Sales Tax
California’s vehicle sales tax system is more complex than most states, combining a base state tax rate of 7.25% with additional county and district taxes that vary significantly based on your registration address. This comprehensive guide explains how to accurately calculate your total vehicle cost using our interactive calculator.
Key Calculation Formula
Total Tax = (Vehicle Price − Trade-in Value) × (State Rate + County Rate)
California offers a unique tax credit: you only pay sales tax on the amount after subtracting your trade-in value.

4 Detailed Calculation Examples & Scenarios
Example 1: New Car Purchase with Trade-in
Purchase Details:
- Vehicle Price: $32,000
- Trade-in Value: $12,000

Tax Calculation:
Trade-in Benefit: Without the trade-in, tax would be $32,000 × 7.75% = $2,480. The trade-in saved $930 in sales tax ($2,480 – $1,550).
Example 2: Private Party Purchase (No Trade-in)
Purchase Details:
- Vehicle Price: $18,500
- County: Los Angeles County (10.25%)
