California’s vehicle and vessel use tax is what you owe when you buy a car, motorcycle, trailer, or boat and no California sales tax was collected at the point of sale. The statewide base rate is 7.25%, with local district taxes on top depending on where the vehicle is registered or the vessel is moored. Payment is due by the last day of the month following the month of purchase, and the DMV will not complete your registration until the tax is paid or an exemption is documented.
When You Owe It
Use tax applies any time you acquire a vehicle or vessel and California sales tax wasn’t collected at purchase.1California Department of Tax and Fee Administration. Sales And Use Tax Law – Section 6201 The most common trigger is a private-party sale between two individuals. It also applies when you buy from an out-of-state dealer that doesn’t collect California tax, or when you purchase online from a seller outside the state.
The obligation is on you as the buyer, not the seller. Unlike a dealer transaction where tax is handled at the register, you have to report and pay it yourself. Registration or transfer of registration cannot be completed until it’s paid.2California Department of Motor Vehicles. Vehicle Industry Registration Procedures Manual – Chapter 4 – Use Tax
The deadline is the last day of the month after the month you bought the vehicle or vessel.3California Department of Tax and Fee Administration. Tax Guide for Purchasers of Vehicles Buy a truck on March 15, the tax is due no later than April 30.
What Your Rate Actually Is
The statewide rate is 7.25%, but almost no one pays exactly that. Local district taxes add anywhere from 0.10% to 2.00%, so combined rates in California typically land somewhere between 7.25% and roughly 10.25%.4California Department of Tax and Fee Administration. California City and County Sales and Use Tax Rate Information
For a vehicle, the rate is based on the address where the vehicle is registered. For a vessel, it’s based on where the vessel is moored.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax You can look up your exact combined rate on the CDTFA website using the applicable address.
Figuring the Taxable Amount
Use tax is calculated on the total purchase price, not just the cash portion. That total includes any loan you assumed, any debt canceled, and the fair market value of any property or services you traded as part of the deal.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax Trade in a motorcycle worth $3,000 and pay $7,000 cash for a car, and the taxable price is $10,000.
If the purchase price on your paperwork looks unusually low compared with similar vehicles, expect the DMV to push back. You’ll be asked to complete a Statement of Facts form (REG 256) explaining the discrepancy. When no purchase price was agreed on at all, the DMV may set the taxable amount using the midpoint between the low and high values in a current vehicle valuation guidebook.6California Department of Motor Vehicles. Calculating Use Tax Amount
Credit for Tax Paid to Another State
Already paid sales or use tax on the vehicle in another state before bringing it here? You can claim a credit for that amount against your California use tax, dollar-for-dollar, but the credit can’t exceed what you owe California.7California Department of Tax and Fee Administration. Sales And Use Tax Law – Section 6406 If the other state’s rate was lower, you pay California the difference. If it was higher, you owe nothing here, but California won’t refund the overage.
Exemptions Worth Knowing
Not every transfer creates a tax bill. Several situations are fully exempt.
Family Transfers
No use tax is due when you buy a vehicle or vessel from a parent, grandparent, child, grandchild, spouse, or domestic partner. Siblings qualify only if both buyer and seller are minors related by blood or adoption. In every case, the seller cannot be in the business of selling that type of property.8California Legislative Information. California Revenue and Taxation Code 6285 (2025)5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax
Transfers into a revocable trust also qualify, as long as the seller keeps full power to revoke, beneficial ownership doesn’t change, and the only consideration is the trust assuming an existing loan secured solely by the property being transferred.8California Legislative Information. California Revenue and Taxation Code 6285 (2025)
Gifts
A genuine gift is exempt, but the CDTFA reads “gift” narrowly. It’s not a gift if you paid cash, traded property, provided services, or assumed a loan in exchange. A vehicle given by an employer as compensation, such as a bonus, is also not a tax-free gift.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax
Involuntary Transfers
When you acquire a vehicle or vessel through circumstances beyond your control, use tax generally doesn’t apply. Examples include a court order, a property settlement in a divorce, inheritance from an estate, or repossession of a vehicle you previously sold.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax
Purchases Made and Used Out of State
Buy a vehicle, vessel, or aircraft outside California and bring it into the state within 12 months, and the law presumes you bought it for California use, making the purchase taxable. The presumption is rebuttable with documentation showing the property was genuinely purchased for use outside California during that first year, such as out-of-state registration records.9California Department of Tax and Fee Administration. Sales And Use Tax Law – Section 6248
The presumption applies to California residents, to vehicles registered in California during those first 12 months, and to nonresidents who use or store the property in California more than half the time during the first year of ownership.9California Department of Tax and Fee Administration. Sales And Use Tax Law – Section 6248
Commercial Vessels
Two exclusions cover working boats. Undocumented vessels used primarily to transport people or property for hire between California and another state or country are excluded, provided the vessel meets minimum gross-income thresholds during its first 12 months of operation. Vessels used principally in commercial deep-sea fishing operations outside California territorial waters also qualify, as long as the owner is regularly engaged in commercial deep-sea fishing with at least $20,000 in annual gross receipts from those operations.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax Publication 52 covers vessels registered with the DMV; vessels documented with the U.S. Coast Guard fall under separate rules in Publication 40.
Military Personnel
Active-duty service members stationed in California but domiciled in another state can qualify for the nonresident military (NRM) exemption, which provides a vehicle license fee exemption on vehicles registered in their names, as long as the vehicle is not operated for hire.10California Department of Motor Vehicles. Nonresident Military (NRM) Exemption Federal protections under the Servicemembers Civil Relief Act and Military Spouses Residency Relief Act may also affect whether personal property is taxable in the state where you’re stationed versus your home state. If you’re active-duty, it’s worth walking through your specifics with the DMV or a military legal assistance office.
How to Pay
Most buyers pay the use tax to the DMV when they register or transfer registration. The DMV collects it and holds registration until the tax is satisfied.2California Department of Motor Vehicles. Vehicle Industry Registration Procedures Manual – Chapter 4 – Use Tax
You can also report and pay directly to the CDTFA through their online portal, where you can pay use tax, claim an exemption, or request a use tax clearance.11California Department of Tax and Fee Administration. CDTFA Online Services Registration A use tax clearance is a document from the CDTFA confirming you qualify for a specific exemption; you bring it to the DMV and register without paying tax there.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax
If you’re filing directly with the CDTFA, the form is the CDTFA-401-E (State, Local, and District Consumer Use Tax Return). You’ll need the Vehicle Identification Number (VIN) or Hull Identification Number (HIN), the purchase date, the total purchase price, and documentation of any tax paid to another state if you’re claiming a credit.
Can’t pay the full amount at registration? The CDTFA offers payment plans you can apply for online. Entering a plan may relieve the 10% late-payment penalty, provided you keep to its terms.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax
Penalties for Paying Late
The standard penalty for unpaid use tax is 10% of the amount due, plus interest that accrues monthly at a rate tied to the federal underpayment rate plus three percentage points.12California Department of Tax and Fee Administration. Regulation 1703
The penalty is much steeper if the CDTFA concludes you registered the vehicle, vessel, or aircraft outside California specifically to avoid the use tax. In that case, the penalty jumps to 50% of the tax owed.12California Department of Tax and Fee Administration. Regulation 1703 Registering in a no-sales-tax state while actually keeping and driving the vehicle in California is the exact pattern this penalty targets, and the CDTFA looks for it.
If You Disagree With the Assessment
If the CDTFA denies your exemption or you disagree with the tax assessed, you still have to pay the DMV to finish your registration. After that, you can file a claim for refund with the CDTFA and dispute the finding through the administrative process.5California Department of Tax and Fee Administration. Publication 52 – Vehicles and Vessels: Use Tax Keep purchase documents, registration records, and any correspondence with the CDTFA for at least four years in case of an audit or dispute.
