NJ Car Tax Calculator: Rate, Trade-Ins, and Surcharges

New Jersey car sales tax is 6.625 percent of the vehicle’s price, and that single rate applies statewide whether you buy new or used, from a dealer or from a private seller.¹ What changes your actual bill is what counts as “the price”: trade-ins lower it, manufacturer rebates don’t, and a separate surcharge kicks in on pricier or thirstier new cars.

The 6.625 Percent Rate

New Jersey applies one uniform sales and use tax rate to motor vehicles. There are no county or municipal add-ons layered on top, so a car bought in Newark is taxed the same as one bought in Cape May. The rate is the same for new and used vehicles: a $30,000 sedan from a dealership and a $12,000 pickup from a neighbor are both taxed at 6.625 percent of the purchase price.²

The Division of Taxation must certify that the correct tax has been paid before the Motor Vehicle Commission (MVC) will issue a title. You cannot defer the tax to a later date or skip it and pay later.

How a Trade-In Lowers Your Taxable Price

If you trade in a vehicle at a dealership, the credit the dealer gives you for your old car reduces the price that sales tax is calculated on. Buy a $35,000 vehicle with a $10,000 trade-in, and you pay 6.625 percent on $25,000, not on the full sticker.³ The $10,000 credit saves you roughly $663 in tax.

This works only when the dealer is the one applying the trade-in credit. If you sell your old car privately and use the cash to fund another private purchase, you pay tax on the full price of the car you buy. Selling separately and buying separately gives you no tax offset.

Why Manufacturer Rebates Don’t Cut Your Tax

New Jersey calculates sales tax on the full price before a manufacturer rebate, not on the discounted amount you actually pay. The state treats a manufacturer rebate like a manufacturer coupon: the seller still receives the full retail price, with part coming from you and part from the manufacturer.⁴

An $18,000 vehicle with a $2,000 manufacturer rebate is still taxed on $18,000. That’s $1,192.50 in tax, not $1,060. Dealer discounts negotiated off the sticker are different: they lower the actual sales price, and the taxable amount drops with it.

The Luxury and Fuel-Inefficient Vehicle Surcharge

On top of the 6.625 percent sales tax, the MVC collects a separate 0.4 percent surcharge when you title a new passenger vehicle that meets either of these:⁵

A sales or lease price of $45,000 or more, or
An EPA average fuel efficiency rating below 19 miles per gallon.

Only one trigger has to apply. A $50,000 sedan rated at 30 mpg owes it because of the price. A $38,000 truck rated at 17 mpg owes it because of the mileage. The surcharge is a one-time fee paid at titling, and it’s calculated on the full sales price before any trade-in or rebate credit.

Two limits matter. The surcharge applies to new vehicles only, so used buyers don’t pay it. And it applies to passenger automobiles, not commercial vehicles. The $45,000 threshold has not changed as of 2026, though legislation has been introduced to raise it to $70,000.

Buying From a Private Seller

Private party sales carry the same 6.625 percent tax; only the collection point is different. Instead of a dealer handling it, you pay when you visit an MVC agency to title the vehicle.²

After the transaction, the Division of Taxation may mail you a questionnaire asking you to verify what you paid. If the price you reported is well below book value, expect to document why. Repair estimates, accident reports, photos of damage, or a bank statement showing the cash you withdrew all help. If you don’t respond, the state can assess tax based on the vehicle’s NADA guide value rather than what you actually paid.

Buying Out of State or Moving to New Jersey

If you buy a vehicle in another state and then register it in New Jersey, you owe New Jersey’s 6.625 percent use tax on the purchase price. The state generally credits you for sales tax already paid to the other state, provided that state offers similar treatment for New Jersey tax payments. You pay only the difference, if any.

Bought a car in a state with a 4 percent rate and paid $1,200 there? You’d owe New Jersey the remaining 2.625 percent when you title it here. If the other state’s rate met or beat 6.625 percent, you owe nothing more. The MVC calculates the credit at titling.

A different rule covers people relocating to New Jersey. Vehicles you purchased, titled, and registered in another state while you were a resident there are exempt from New Jersey sales tax when you later move in and register them here.⁶

How Leases Are Taxed

Leasing runs on a different tax calculation, and the term of the lease decides which rule applies.³

Leases longer than six months: sales tax is due on the entire lease amount upfront, at signing.
Leases of six months or less, or open-ended leases: sales tax is due on each individual payment as you make it.

Most standard three-year leases fall under the long-term rule, so plan for the full tax at signing. On a lease with $18,000 in total payments, that’s roughly $1,193 due at the start. A trade-in still reduces the taxable base on a lease; a manufacturer rebate still does not.

Transfers That Owe No Sales Tax

Some vehicle transfers are exempt from the 6.625 percent tax entirely. The most common ones:⁶

Gifts. A vehicle received as a gift owes no sales tax. The word “GIFT” must appear as the sales price on the title paperwork, and the MVC may ask for additional documentation if it suspects paperwork has been altered.
Inheritance. Vehicles acquired by an heir, a beneficiary under a will, or a trust beneficiary are exempt.
Disabled veterans. Veterans who receive funds from the Veterans Administration to purchase a vehicle pay no sales tax on that purchase.
Active-duty service members. New Jersey residents stationed out of state who buy a vehicle elsewhere can defer tax until the vehicle enters New Jersey after release from active duty, with a Letter of Deferment from the Division of Taxation.

Exemptions are not automatic. You have to visit an MVC agency in person with supporting documentation to claim one.

Electric Vehicles No Longer Get a Break

New Jersey’s full sales tax exemption for zero-emission vehicles ended on October 1, 2024, and phased out completely by mid-2025. Starting July 1, 2025, ZEVs are taxed at the full 6.625 percent like any other vehicle.⁷ If you’re buying an electric car in 2026, budget for the full rate.

A Worked Example

Here’s how the pieces fit together for a typical dealer purchase:

Start with the negotiated sales price on your purchase agreement.
Subtract your trade-in credit. What’s left is your taxable base.
Multiply that base by 0.06625 for sales tax.
If the vehicle is new and the full sales price (before trade-in) is $45,000 or more, or its EPA fuel economy is below 19 mpg, multiply the full sales price by 0.004 and add that as the luxury surcharge.⁵

Say you buy a new SUV for $52,000 and trade in your old vehicle for $12,000. Your sales tax base is $40,000, so the 6.625 percent tax comes to $2,650. Because the full price crosses $45,000, you also owe the 0.4 percent surcharge on $52,000, adding $208. Combined state tax: $2,858.

Now add a $3,000 manufacturer rebate to that same deal. Your out-of-pocket drops, but the tax math doesn’t change: sales tax is still $2,650 on the $40,000 post-trade-in base, and the surcharge is still $208 on the $52,000 price.⁴ The rebate reduces what you pay the dealer, not what the state taxes.
