New Jersey Car Sales Tax Calculator – Fast, Free & Accurate

How Car Sales Tax Works in New Jersey

• Standard Sales Tax Rate: New Jersey applies a 6.625% sales tax on most vehicle purchases.
• Zero-Emission Vehicle (ZEV) Exemption: Electric cars and other zero-emission vehicles are completely exempt from sales tax.
• Luxury/Low-MPG Surcharge: If the car’s price is over $45,000 and the fuel economy is under 19 MPG, New Jersey adds a 0.4% surcharge.
• Trade-In Credit: If you trade in a vehicle, the value of that trade-in reduces your taxable amount.

Example:

• Vehicle price: $50,000
• Trade-in: $10,000
• Net price: $40,000
• Tax (6.625%): $2,650

If the car qualifies for the surcharge, you’d add an extra 0.4% of the taxable amount.

Special Rules to Keep in Mind

• Exemption for Electric Vehicles: If you’re buying an EV like a Tesla or Nissan Leaf, you pay no sales tax in NJ. This can save thousands compared to gas-powered cars.
• Trade-In Benefits: Trading in a car can cut down your taxable amount significantly. For example, trading in a $15,000 car on a $35,000 vehicle means you’re only taxed on $20,000.
• Luxury Gas Guzzler Surcharge: The 0.4% surcharge doesn’t apply to all expensive cars—only those over $45,000 with poor fuel economy. A $50,000 luxury EV, for instance, wouldn’t face this extra cost.

Why This Matters for Car Buyers

Car buying is stressful enough without surprise costs. Knowing your tax obligation upfront helps you:

• Budget better – Plan for total expenses before stepping into a dealership.
• Compare cars fairly – A luxury SUV with a surcharge may cost more in tax than a similarly priced hybrid.
• Avoid surprises – Walk into negotiations with clear expectations.
