Many people searching for sales tax calculator New Jersey are buyers, car dealers, small business owners, or private sellers who need a quick answer for a vehicle or retail purchase.

State rate vs. local surtaxes

New Jersey has a flat statewide sales tax of 6.63%. Local surtaxes are less common but special rules may apply. Always do a ZIP code or address lookup for the precise rate before completing a purchase. Examples include Newark, Jersey City, and Paterson.

Why vehicle sales tax is different in New Jersey

• Trade-in credit — A dealer trade-in reduces the taxable amount (purchase price − trade-in value).

• Used-car rules / value bands — Used vehicles may have specific valuation bands or caps.

• Special cases — Leased vehicles, dealer paperwork fees, and private-party transfers can trigger different tax collection rules.

How to find the exact rate for your purchase

• Use a ZIP-based lookup by searching “new jersey sales tax lookup”.

• Ask the dealer for a tax breakdown.

• Check the official source: search “New Jersey Division of Taxation sales tax lookup”.

• For private purchases, verify if compensating use tax applies.

Manual calculation: copy/paste friendly formulas for WordPress

state_rate = 0.0663
local_rate = 0.00
total_rate = state_rate + local_rate
purchase_price = 30000.00
total_sales_tax = purchase_price * total_rate
final_price = purchase_price + total_sales_tax

trade_in_value = 5000.00
taxable_amount = max(0, purchase_price - trade_in_value)
sales_tax_on_taxable = taxable_amount * total_rate
final_price_after_trade_in = taxable_amount + sales_tax_on_taxable

Example calculation (practical)

Inputs:

• EXAMPLE_PRICE = $30,000

• EXAMPLE_LOCAL_RATE = 0.00

• EXAMPLE_TRADE_IN_VALUE = $5,000

Step 1 — compute total rate:

• total_rate = 0.0663 + 0.00 = 0.0663

Step 2 — tax on the full purchase:

• Tax = $30,000 × 0.0663 = $1,989.00

• Final price = $30,000 + $1,989.00 = $31,989.00

Step 3 — apply trade-in credit:

• Taxable amount = $30,000 − $5,000 = $25,000.00

• Sales tax = $25,000 × 0.0663 = $1,657.50

• Final price after trade-in = $25,000 + $1,657.50 = $26,657.50

Filing, payments and useful admin notes

• Dealers collect sales tax at the point of sale and remit it to the New Jersey Division of Taxation.

• Private-party purchases may require compensating use tax payment.

• Look for sales tax exemption possibilities for eligible organizations and purchases.
