California Car Sales Tax Explained
Which rate applies, what's taxed, why your trade-in doesn't help, and when a private or family sale is exempt.
California charges sales tax on a car at the combined rate where you register it: 7.25% statewide plus local district taxes, up to 11.75% in the cities we track. The tax applies to the full selling price. A trade-in doesn't reduce it, and neither does a manufacturer rebate. Buy from a private seller and you pay the same rate as use tax at the DMV, unless the car is a gift or comes from a close family member.
Which rate applies
The California Department of Tax and Fee Administration (CDTFA) bases the rate on the address where the vehicle is registered, not where you buy it. Buying in a low-rate city and registering at home in a higher-rate city means you pay your home rate. Combined rates in some large cities:
| City | Combined rate | Tax on a $35,000 car |
|---|---|---|
| Los Angeles | 10.25% | $3,588 |
| San Diego | 7.75% | $2,713 |
| San Jose | 10% | $3,500 |
| San Francisco | 8.625% | $3,019 |
| Fresno | 8.35% | $2,923 |
| Sacramento | 8.75% | $3,063 |
Rates as of October 1, 2026. Local rates can change at the start of any calendar quarter as district taxes begin or expire; find yours in the district rate lookup or on our sales tax by city pages.
What is taxed
- The full purchase price, however you pay it: cash, a loan, a loan you take over, or goods or services traded for the car.
- No trade-in deduction. California is one of the states that taxes the price before the trade-in allowance.
- Manufacturer rebates you assign to the dealer stay in the taxable price. A discount the dealer gives on its own does lower it.
- The dealer documentation fee is taxable. It is capped at $85 for dealers in the DMV's business partner program and $70 for others (Vehicle Code 4456.5).
Not taxed: DMV registration and license fees, and optional service contracts sold separately.
A worked example
You buy a $35,000 car from a dealer, trade in a car worth $8,000, sign over a $1,500 manufacturer rebate, pay the dealer's $85 doc fee, and register it in Los Angeles (10.25%):
| Selling price | $35,000 |
| Trade-in (not subtracted for tax) | — |
| Manufacturer rebate (still taxable) | — |
| Doc fee | $85 |
| Taxable amount | $35,085 |
| Sales tax at 10.25% | $3,596 |
The trade-in and the rebate lower what you owe the dealer by $9,500, but not the tax. In a state that subtracts trade-ins, the tax would have been figured on $27,085.
Private-party sales
Buy from someone who isn't a dealer and no sales tax is collected at the sale. You owe use tax at the same rate, normally paid to the DMV when you register the car in your name. The tax is on the price you paid, including any loan you took over. If you buy without registering, the tax is due to CDTFA by the last day of the month after the month you bought it.
When no tax is due
- Gifts. The owner gives the car freely, with no payment, trade, service or debt taken on in return. A car from your employer as a bonus is not a gift.
- Family sales. A purchase from a parent, grandparent, child, grandchild, or spouse or registered domestic partner, who isn't in the business of selling cars. Siblings count only if both are minors. Step-relatives don't count unless there was an adoption, and ex-spouses don't count after the divorce.
- Involuntary transfers, such as a court order, a divorce property settlement or an inheritance.
- Military transfers. An active-duty service member who bought and took delivery of the car outside California before receiving orders here.
The DMV may ask for proof, such as a signed gift statement or birth certificates, or for a CDTFA use tax clearance.
Cars bought out of state
A car bought outside California and brought here within 12 months is presumed bought for use in California, and use tax applies, if you are a California resident, if it is registered with the California DMV during that first year, or (for a nonresident) if it is used or stored here more than half the time. You get a credit for sales tax paid to the other state. For example, if you paid $1,500 there and California's tax is $2,000, you owe $500.
Lease buyouts
Buying your leased car at the end of the lease is a taxable sale. If the leasing company doesn't collect the tax, you pay use tax at the DMV when you register it.
