AutoTaxCalculatorCA sales tax on a used car
California car tax = selling price × (7.25% + district tax where you register). A $22,000 used car registered in an area with a 1% district tax owes $1,815, even with a $5,000 trade-in.
New and used vehicles are taxed the same way. The statewide rate is 7.25%. Many cities, counties and communities add voter-approved district taxes on top. For vehicles, the district tax that applies is the one where the car will be registered, not where the dealership is. CDTFA's own example: a dealer in a special tax district selling a car that will be registered in a county with no district taxes charges only the 7.25% statewide rate.
City district taxes only apply to addresses inside incorporated city limits. If you live in an unincorporated area next to a city, you may not pay that city's district tax.
No trade-in deduction in California
This catches many buyers. CDTFA's guide for dealers says the allowance for a trade-in cannot be excluded from the taxable amount. If you buy a $20,000 car and trade in a $4,000 car, tax is still based on $20,000. An inflated trade-in allowance can't be treated as a hidden discount either.
Discounts versus rebates
- Dealer discounts aren't taxed. A $15,000 car discounted 10% is taxed on $13,500. The paperwork has to show the discount clearly.
- Manufacturer rebates you assign to the dealer stay in the taxable price. If a $1,000 factory rebate goes toward your payment, it's still part of the dealer's gross receipts.
- Factory-to-dealer incentives that don't require the dealer to cut your price only lower the dealer's cost. They don't change your tax.
Private-party purchases: use tax at DMV
Buying from a person who isn't required to hold a dealer's license or seller's permit is generally subject to use tax, collected when you register the vehicle with DMV. The rate is the same as sales tax and is set by the address where the car is registered. It's based on the total purchase price: cash, any loan you pay off or take over, and the fair market value of property or services you trade or exchange. If you swap your old car plus cash for someone's truck, your old car's value counts toward the taxable price.
If you buy from a private party in California only to drive the car out of state and use it there, you don't owe California use tax.
Family purchases and gifts
Buying from a parent, grandparent, grandchild, child, spouse or domestic partner isn't subject to use tax. Minors buying from a minor brother or sister (by blood or adoption) are exempt too. The exemption doesn't apply if the family member is a licensed California dealer, if the car comes out of a revocable living trust to a family member who isn't a trustee, or if the seller is a step-relative without a legal adoption. Genuine gifts are covered separately in CDTFA Publication 52. DMV can process many family transfers without a use tax clearance.
Worked examples
$22,000 used car from a dealer, $5,000 trade-in, 1% district tax
- Taxable amount: $22,000 (the trade-in isn't deducted)
- Tax: $22,000 × 8.25% = $1,815.00
$12,000 car from a private seller, registered where there's no district tax
- Use tax at DMV: $12,000 × 7.25% = $870.00
Buying your mother's car for $8,000
- Purchase from a parent: no use tax
Registration and VLF are separate
Sales or use tax is a one-time charge. California DMV also charges yearly registration, the 0.65% vehicle license fee (VLF) and other fees. Our California registration fee calculator covers those.
