The price on the windshield isn't what you'll actually pay for a car in New Jersey. Sales tax, MVC fees and — at a dealer — documentation and other fees can add thousands of dollars. Here's what each charge is, which ones are fixed by the state, and which ones you can negotiate.
New Jersey sales tax: 6.625%
New Jersey charges 6.625% sales tax on the purchase price of a vehicle.
- At a dealer, the dealer collects the tax and sends it to the state. If you trade in a car as part of the same deal, the trade-in value is subtracted first, so you only pay tax on the difference.
- In a private sale, you pay the tax at the MVC when you title and register the car, based on the price on the title and bill of sale. There's no trade-in credit, because selling your old car separately isn't a trade-in.
Example — dealer purchase with a trade-in
| Item | Amount |
|---|---|
| Vehicle price | $25,000 |
| Trade-in value | −$8,000 |
| Taxable amount | $17,000 |
| Sales tax (6.625%) | $1,126.25 |
Without the trade-in, the tax on $25,000 would be $1,656.25 — so trading in at the dealer saved $530 in tax. Keep that in mind when you compare a dealer's trade-in offer with selling your car privately.
MVC title and registration fees
These are set by the state and aren't negotiable:
| Fee | Amount |
|---|---|
| Title fee | $60 ($85 if there's a lien/loan) |
| Registration | Roughly $35–$85 a year, depending on the vehicle |
| Late title transfer (private sale) | $25 after 10 working days |
Plates, specialty plates and other options can add more. Check nj.gov/mvc for the current fee for your vehicle.
Dealer fees: what's legitimate
Documentation ("doc") fee. Dealers charge this for preparing the paperwork. New Jersey doesn't set a maximum, so it varies a lot from one dealer to the next — often several hundred dollars. It should be listed clearly on your buyer's order.
Government pass-through fees. Sales tax, title and registration that the dealer collects on the state's behalf. These should match the MVC amounts.
Add-ons and "prep" charges. Dealer prep, etching, nitrogen tires, paint protection, advertising fees and similar items are optional or negotiable. If you didn't ask for it, ask for it to be removed.
Financing costs
If you finance, the tax and fees are usually rolled into the loan, so you pay interest on them too. Use the payment calculator on any NJCarListings.com listing to see how price, down payment, trade-in, credit and loan length change your monthly payment — it includes NJ sales tax automatically.
