New Jersey Credentials for Importing Registration

To import your existing New Jersey sales tax registration into Kintsugi, you'll need to provide a few details issued by the New Jersey Division of Taxation when you registered your business. New Jersey manages its tax accounts through the New Jersey Tax Portal, the state's online portal for filing, paying, and managing business taxes. Once imported, Kintsugi can manage your New Jersey sales tax filings.

Required Credentials

When importing an existing New Jersey sales tax registration into Kintsugi, you'll need the following:

• Taxpayer ID

• Portal Access Passcode

• Business Name

• Tax Type

• Amount from Line 1 of most recent return

What's My Taxpayer ID?

Your Taxpayer ID (also referred to as your Taxpayer Identification Number or TIN) is the unique number assigned to your business by the New Jersey Division of Taxation for identification purposes when filing returns or making payments.

Where to find it

You can find your Taxpayer ID in any of the following places:

• Your New Jersey Tax Portal account. Log in at taxportal.nj.gov and review your Taxpayer Entity profile to locate your Taxpayer ID.

• New Jersey Division of Taxation correspondence. Any notices or letters from the Division of Taxation will reference your Taxpayer ID.

• Your Welcome Letter. When you registered, the New Jersey Division of Taxation sent a Welcome Letter containing your account details, including your Taxpayer ID.

What's My Portal Access Passcode?

Your Portal Access Passcode is a 6-digit code used to file returns and make payments on the New Jersey Tax Portal. If your business was registered before May 2025 and you were originally assigned a 4-digit PIN, you can convert it to a 6-digit passcode by adding two leading zeros (e.g., PIN 1234 becomes 001234).

Where to find it

You can find your Portal Access Passcode in any of the following places:

• Your Welcome Letter. The New Jersey Division of Taxation sent a Welcome Letter upon registration that includes your assigned PIN or passcode.

• Your New Jersey Tax Portal account. Log in at taxportal.nj.gov and navigate to your account settings to retrieve or update your passcode.

• New Jersey Division of Taxation correspondence. If you've requested a new passcode, it will be included in correspondence from the Division of Taxation. You can also request a new PIN by contacting the NJ Tax Portal Help Desk at 609-772-8577.

• New Jersey Division of Taxation website. You can also request for your Business Tax PIN here. Just fill and submit the form and they will email your PIN to you.

What's My Business Name?

Your Business Name is the official legal business name on file with the New Jersey Division of Taxation, as provided when you registered your sales tax account.

Where to find it

You can find your registered Business Name in any of the following places:

• Your New Jersey Tax Portal account. Log in at taxportal.nj.gov and review your Taxpayer Entity profile to confirm the name on file.

• Your Welcome Letter. Your registered business name is included in the Welcome Letter sent by the New Jersey Division of Taxation upon registration.

• New Jersey Division of Taxation correspondence. Any notices or letters from the Division of Taxation will reference your registered business name.

What's My Tax Type?

Your Tax Type is the specific category of tax associated with your account (e.g., Sales & Use Tax). New Jersey may have registered your business under one or more tax types.

Where to find it

You can find your Tax Type in any of the following places:

• Your New Jersey Tax Portal account. Log in at taxportal.nj.gov and navigate to your tax account summary to view the tax types associated with your business.

• Your Welcome Letter or Certificate of Registration. The tax type(s) you are registered for are referenced in documentation issued at the time of registration.

What's the Amount from Line 1 of My Most Recent Return?

This is the dollar amount reported on Line 1 of the most recent sales tax return you filed with the New Jersey Division of Taxation. It is used to verify your identity and account ownership.

Where to find it

You can find this amount in any of the following places:

• Your filed return. Locate the most recent Sales and Use Tax return you submitted. Line 1 typically reflects your gross receipts or taxable sales for the period.

• Your New Jersey Tax Portal account. Log in at taxportal.nj.gov and navigate to your filing history to access previously submitted returns.

Next Step

Once you provide the required credentials, Kintsugi will initiate the third-party access request. You do not need to validate or approve the request separately, as Kintsugi will complete this step on your behalf.

Once access is confirmed, Kintsugi can continue with the registration import setup in the app.
