Identity Theft

What is Identity Theft?

When someone illegally obtains your personal or financial information such as your social security number (SSN), date of birth, or credit card number(s) and uses it without your permission.

How Identity Theft may affect your tax records

One way an identity thief may use a stolen SSN is to file a tax return in order to receive an illegal tax refund. You may learn that this has happened if you receive an unexpected notice(s) or letter(s) from either the New Jersey Division of Taxation or the Internal Revenue Service (IRS) regarding your tax records. For example, the Division of Taxation may notify you that a return was already filed using your SSN or that W-2 information reported isnít the same as the information on your original filing. If this happens you may be a victim of identity theft.

Identity theft can affect your current, past or future tax records.
