Contact Us - Business Tax PIN Request

This page is for Business Tax PIN inquiries and can only be used if your business is already registered with the Division of Revenue & Enterprise Services (DORES).

Do not use this service if your business is not required to register to withhold New Jersey Income Tax and you only need to submit Payroll Tax Informational Returns (NJ-W3/W2/1099).

Your Business Tax PIN is printed on the "Welcome Letter" you received when you first registered your business. Generally, the 4-digit PIN is the same used to submit New Jersey tax payments and returns either online or by phone (e.g., Withholding Tax returns (Forms NJ-927/NJ-500 or Form NJ-927-W) or Sales and Use Tax returns (Forms ST-50/51)). If you need help obtaining your PIN, complete the form below.

In order for us to process your PIN request, you must provide us with your New Jersey Corporate ID Number. If you do not know your New Jersey Corporate ID number, you can access it through the DORES website using the "Business Entity Name Search."

If you do not have a New Jersey Corporate ID number or you are unable to use this form, fax your request to 609-633-6444. and include your Federal Employer Identification Number (FEIN) or Social Security number.


Please check your email address carefully before you send your message. When you contact the Division of Taxation through the website we respond by email. If a response is required and you do not provide a valid email address, we will not be able to reply to your inquiry.
