Tax Base in California
Purchase price (or fair market value for private party sales under the DMV use tax process)
For private party sales, California assesses use tax based on the purchase price you report when registering. If the DMV determines the purchase price is unreasonably low, they may assess use tax on the market value. Undervaluing is tax fraud.
Trade-In Sales Tax Credit in California
California does NOT give a sales tax credit for trade-ins. The full purchase price of the new/replacement vehicle is taxable regardless of any trade-in value applied by the dealer.
Example calculation:
Los Angeles purchase at $15,000: $15,000 × 10.25% = $1,537.50 in use tax due at DMV registration.
Sales Tax on Private Party Used Car Sales in California
Private party used car purchases are subject to California use tax (the equivalent of sales tax for private sales). Use tax is collected by the DMV at the time of registration — not at the time of sale. You pay it when you register the vehicle at DMV.
When you register a privately purchased vehicle, DMV calculates use tax based on the purchase price on the bill of sale. Have your bill of sale ready at registration. The use tax is paid at the DMV counter.
Sales Tax on Dealer Used Car Purchases in California
Dealers collect California sales tax at the point of sale. The dealer adds sales tax to the purchase price, collects it, and remits it to the state. The sales tax rate is the rate for the dealer's business location.
When buying from a California dealer, your sales tax rate is based on the DEALER'S county, not where you live. If you buy from a San Francisco dealer but live in Sacramento, you pay San Francisco's tax rate.
Buying a Car Out of State and Registering in California
If you buy a vehicle in another state and bring it to California for registration, California use tax applies based on the purchase price. You can credit any tax you paid to the other state against California's use tax — but only if the other state's tax rate was lower than California's.
Most states have lower sales tax rates than California. If you paid 4% to Nevada, California will collect the difference (3.25%+ depending on your county). Bring the out-of-state bill of sale and any tax receipts to the California DMV.
