How to register for a sales tax permit in New Jersey
Sidr Tax creates the sales tax account for you. However, this state requires that you have your own login and we access your account as a third-party.
After Sidr Tax applies for a sales tax permit on your behalf, you will receive your New Jersey sales tax ID, PIN, and filing frequency in the mail. You will either receive a 4-digit PIN or a 6-digit passcode.
Once you receive your sales tax ID and PIN in the mail, you can create a login at New Jersey Tax Portal to access your sales tax account.
