New Jersey sales tax on cars is 6.625 percent of the sale price, and it applies to new vehicles, used vehicles, dealership deals, private sales, and cars bought out of state that you bring home to register.1Justia. New Jersey Revised Statutes Section 54:32B-3 – Taxes Imposed There is no separate county or local add-on, so the rate is the same anywhere in the state. The tax is calculated on what you actually agreed to pay, not on sticker price or book value, with some adjustments for trade-ins, discounts, rebates, and dealer fees.
How the Taxable Price Is Figured
The 6.625 percent rate is straightforward. The number it gets applied to is where buyers usually lose or save money.
Trade-Ins Lower the Tax
If you trade a vehicle in as part of the deal, its value is subtracted from the purchase price before tax is calculated. Buy a $30,000 car and trade in one worth $10,000, and you owe tax on $20,000.2Cornell Law School. N.J. Admin. Code 18:24-36.2 – Application of Sales Price On a higher-value trade, the savings are real.
Dealer Discounts Lower the Tax; Manufacturer Rebates Do Not
A dealer discount reduces the selling price, so it reduces the taxable base. Knock $2,000 off a $25,000 car and you pay tax on $23,000.2Cornell Law School. N.J. Admin. Code 18:24-36.2 – Application of Sales Price
A manufacturer rebate is treated as a payment from a third party, not a price cut. The tax is calculated on the pre-rebate amount.2Cornell Law School. N.J. Admin. Code 18:24-36.2 – Application of Sales Price A $500 rebate on a $20,000 car still leaves you taxed on the full $20,000; the rebate just reduces what you write a check for after tax.
Documentation and Delivery Fees Raise the Tax
Dealer documentation fees, delivery charges, and other costs billed to the buyer are added to the vehicle price before the 6.625 percent is applied.2Cornell Law School. N.J. Admin. Code 18:24-36.2 – Application of Sales Price New Jersey does not cap documentation fees, so they vary from one dealership to the next. Ask for a full breakdown before signing; every dollar in fees adds to the tax. State title and registration charges, by contrast, are excluded from the taxable base.3NJ Division of Taxation.

Buying a Car Out of State
Crossing a state line to buy a cheaper car does not get you out of New Jersey tax. If you bring the vehicle home to register and use it here, you owe 6.625 percent use tax, which is effectively the same rate as the sales tax.1Justia. New Jersey Revised Statutes Section 54:32B-3 – Taxes Imposed
What you can do is claim a credit for sales tax you already paid to the other state.4Justia. New Jersey Revised Statutes Section 54:32B-11 On a $30,000 car bought in a 4 percent state, you’d have paid $1,200 there; New Jersey’s use tax on that same $30,000 would be $1,987.50, so you’d owe $787.50 at the MVC. If you bought where there’s no sales tax, you owe the full 6.625 percent. If the other state’s rate was higher than ours, the credit is capped at the New Jersey amount, so you never pay more than 6.625 percent total. Bring your out-of-state purchase receipt and proof of tax paid to registration.
When You Don’t Owe Sales Tax
A few transactions are exempt. The common ones:
Genuine gifts. If a vehicle is given to you with no payment, trade, or other exchange of value, no sales tax is due, regardless of your relationship to the giver.5NJ.gov. New Jersey Consumer Automotive Tax Guide The title paperwork must show “GIFT” as the sale price, and the MVC may ask for more documentation if the transaction looks suspect.6NJ.gov. Vehicles Exempt From Sales Tax
Inherited vehicles. Cars received by an heir, a trust beneficiary, or through a will are exempt.6NJ.gov. Vehicles Exempt From Sales Tax
Non-resident purchases. If you have no permanent home in New Jersey and don’t use the vehicle for any business, trade, or employment in the state, you can buy here and take the car out to register it without owing New Jersey tax.7Justia. New Jersey Revised Statutes Section 54:32B-10 – Sale of Motor Vehicle, Aircraft, Boat, Vessel, Exemption From Tax The seller will want documentation before writing up the sale tax-free.
One exemption that used to exist no longer does: zero-emission vehicles. The EV exemption was repealed by P.L. 2024, c. 19, phased down to a 3.3125 percent transitional rate from October 1, 2024 through June 30, 2025, and ended entirely on July 1, 2025. EVs purchased today pay the full 6.625 percent.8NJ.gov. Zero Emission Vehicles Exemption – Sales and Use Tax
Leased Vehicles Are Taxed Differently
A lease isn’t taxed on the car’s value. It’s taxed on the total of the lease payments, and when you owe the tax depends on how long the lease runs.
On a long-term lease (more than six months), tax on the entire lease amount is due up front, collected by the dealer at signing. Your monthly payment itself doesn’t carry sales tax, though it may include a reimbursement if the dealer financed that upfront amount for you. On a short-term lease (six months or less, or open-ended), tax is charged on each payment as it comes due.5NJ.gov. New Jersey Consumer Automotive Tax Guide
A trade-in reduces the taxable base of a lease the same way it does a purchase. Manufacturer rebates are included in the base, same logic as a purchase.3NJ Division of Taxation. Summary of Changes in Tax Base for Motor Vehicle Lease Transactions Under the Streamlined Sales and Use Tax Law
If you end a long-term lease early, you’ve paid tax on months you’ll never use. You can claim a refund for the sales tax tied to the unused portion, either through the dealership or by filing Form A-3730 directly with the Division of Taxation. The claim must be filed within four years of the original payment.5NJ.gov. New Jersey Consumer Automotive Tax Guide
Who Collects the Tax
At a licensed New Jersey dealership, the dealer collects the sales tax at closing and remits it to the state. It must appear as a separate line on your invoice, and you don’t have to do anything further.5NJ.gov. New Jersey Consumer Automotive Tax Guide An authorized out-of-state dealer may also collect New Jersey tax at the time of sale.
In a private sale, no one collects it for you. You pay the tax yourself at the Motor Vehicle Commission when you transfer the title and register the car; the MVC won’t issue the new title or plates until it’s paid.5NJ.gov. New Jersey Consumer Automotive Tax Guide If you qualify for an exemption, bring Form ST-10 (Motor Vehicle Sales and Use Tax Exemption Report) with supporting paperwork.6NJ.gov. Vehicles Exempt From Sales Tax
Reporting a lower price than you actually paid to shrink the tax bill is illegal and exposes you to penalties and interest. The state can assess the vehicle’s true value on its own, so a lowball figure is unlikely to pass unnoticed.
Getting the Tax Back Under the Lemon Law
If a new car qualifies as a lemon and the manufacturer buys it back, the refund includes the sales tax you originally paid, along with license fees, registration fees, and finance charges.9Cornell Law School. N.J. Admin. Code 13:45A-26.11 – Computation of Refund The manufacturer can deduct a mileage-use charge for the time you drove the car before the defect was reported, but the tax tied to the refunded price comes back to you as part of the settlement.
