How to Collect Sales Tax in Princeton

Since New Jersey is a destination-based sales tax state, the same applies to Princeton as well. This means sales tax is calculated based on the buyer's ship-to-location rather than the seller's ship-from-location.

New Jersey sales tax rules apply to all intrastate and interstate sales made to a New Jersey delivery address.

For instance, if your business is located in Las Vegas, Nevada, and you sell to a buyer in Newark, New Jersey, you should charge the buyer the New Jersey sales tax rate.  

Since New Jersey has a single sales tax rate of 6.625%, all sales sourced to New Jersey will be charged this single rate — unless you’re in a UEZ or a region where special taxes apply.

Note: If the delivery address is based outside New Jersey, New Jersey sales tax rules don’t apply in most cases.
