Sacramento Car Sales Tax: Rates, Taxable Amount, and Exemptions

The Sacramento car sales tax is 8.75% inside Sacramento city limits and 7.75% in unincorporated parts of Sacramento County, applied to the full purchase price of the vehicle.¹ California does not let you subtract a trade-in to lower the taxable amount, so on a $30,000 car at the city rate you owe $2,625 regardless of what your old vehicle was worth.²

Which Rate Applies to You

The rate is tied to where you register and keep the vehicle, not where you buy it. If you live inside Sacramento city limits and drive to a dealership in a lower-tax area, you still owe 8.75% based on your home address.³ Other cities in the county have their own totals. Elk Grove is 8.75%, Citrus Heights is 7.75%, and unincorporated areas sit at 7.75%.¹

If you are unsure which rate applies at your address, the CDTFA has an online rate lookup tool.⁴

What Counts as the Taxable Amount

California taxes the full agreed-upon selling price. Unlike roughly 40 other states, California does not allow a trade-in deduction. Buy a $30,000 car and trade in a vehicle worth $10,000 and sales tax still applies to the whole $30,000.²

Manufacturer rebates and factory incentives stay in the taxable total. A $2,000 cash-back rebate from the manufacturer is treated as a payment from the manufacturer to you, not a reduction in price, so you pay tax on it.⁵ Federal EV tax credits work the same way for California purposes and do not reduce what you owe the state.⁶

Dealer discounts are the exception that helps you. When a dealership voluntarily lowers the selling price, tax is calculated on the reduced price. A $2,000 manufacturer rebate saves you nothing on tax; a $2,000 dealer discount at 8.75% saves you $175.⁵

Buying from a Private Seller or Out of State

When you buy from a private seller, no dealer collects sales tax for you. You owe use tax instead, which is the same rate and serves the same purpose, and reporting it is your responsibility as the buyer.⁷ The same rule applies if you buy from an out-of-state seller or take delivery outside California.

Most buyers pay use tax when they register at the DMV. If you do not go through DMV registration for some reason, you must report and pay directly to the CDTFA through its online portal.³ The state checks reported purchase prices against market values, so understating the price on title documents invites scrutiny.

How Leases Are Taxed

If you lease, California treats each lease payment as a taxable rental. Sales tax applies to your monthly payments, including any upfront capitalized cost reduction, which the state views as an advance rental payment.⁸ The dealership collects it, so you will usually see the tax itemized on your monthly statement.

A lease buyout at the end of the term is a separate taxable transaction. You owe use tax on the residual value you pay to acquire the vehicle.³

Transfers That Are Exempt

A handful of transfers avoid sales or use tax entirely. The most common is a family transfer. California exempts sales between a spouse, parent, grandparent, child, or grandchild. Sibling-to-sibling transfers are exempt only if both the buyer and seller are minors.⁹ The seller cannot be in the business of selling vehicles, so a parent who runs a used car lot cannot claim the exemption on inventory.

To claim the family exemption, complete a Statement of Facts form (REG 256) at the DMV identifying the relationship between buyer and seller.¹⁰ Vehicles received as genuine gifts are also exempt. Write “gift” on the back of the title in place of a purchase price, and the recipient completes the same REG 256 form.¹¹

Buyers who purchase a vehicle for use outside California may qualify for an exemption if the car is removed from the state promptly, subject to documentation rules in the CDTFA vehicle tax guide.³

When and How to Pay

Dealership purchases are straightforward: the dealer collects the tax at the point of sale and folds it into your financing or paid-at-signing total. Private party and out-of-state purchases are different. Your use tax payment is due by the last day of the month following the month you bought the vehicle, so a car bought any day in March must be paid by April 30.³

Miss that deadline and the CDTFA adds a 10% penalty on the unpaid use tax, plus interest for each month or partial month the balance remains outstanding.¹² Late registration carries its own separate penalty structure through the DMV. For vehicles already registered in California, the DMV penalty starts at 10% of the vehicle license fee if you are 1 to 10 days late and climbs to 160% of the license fee after two years. Registration and CHP late fees stack on top. For a vehicle never previously registered in California, the penalty starts at 40% of the license fee if you are under a year late.¹³

You can pay use tax and complete registration at any DMV field office, through the DMV’s online portal, or directly through the CDTFA’s online services if you need to report use tax separately from registration.³
