What this notice is about

We verified your identity theft claim. We placed an indicator on your tax account and will monitor it to help prevent future fraud.

What you need to know

No additional action is needed on your part. Keep filing your tax returns by the deadline as required.

You’ll need to use an Identity Protection Personal Identification Number (IP PIN) when you file your future tax returns. It’s a 6-digit number assigned to eligible taxpayers to help prevent the misuse of their taxpayer identification number (TIN) on fraudulent federal income tax returns. The IRS will send you a new IP PIN each year.

If you prefer to receive an IP PIN sooner than early December for the upcoming processing year, you can request an IP PIN online. Once you request it online, you’ll be automatically enrolled in paperless IP PIN assignment. You’ll need to sign into your account annually to retrieve your new IP PIN.

You may want to

  • Review the IRS Identity Theft Central page for more information.
  • Visit the Federal Trade Commission (FTC) at IdentityTheft.gov for guidance.
  • Monitor all your personal financial accounts and credit report for suspicious or unauthorized activities.
  • Request, or have your authorized third-party request, a redacted copy of the fraudulent tax return that was filed using your name and TIN. See Instructions for requesting copy of fraudulent returns.
  • File a complaint with the FTC at IdentityTheft.gov or call 877-438-4338, TTY: 866-653-4261, if you think your dependent’s personally identifiable information (PII) was compromised.

What does the identity theft indicator mean for my account?

The indicator doesn’t affect your ability to file your tax return, make payments or get a refund. Whenever your account has the identity theft indicator, you’ll need to use an Identity Protection Personal Identification Number (IP PIN) when you file your tax return.

How long will the indicator stay on my account?

The indicator will stay on your account until you specifically request that we remove it.

What happens if someone tries to file a fraudulent tax return with my taxpayer identification number?

If someone other than you attempts to file a tax return using your taxpayer identification number, it won’t be processed. We’ll detect it and alert you to potential identity theft.

Who can I contact for help with identity theft?

You can call 800-908-4490 for help with identity theft problems related to your account. You can also find the phone number on the notice we sent you.

Where can I find more information on preventing identity theft?

The Federal Trade Commission (FTC) offers support, guidance and resources related to consumer protection, such as:

  • Preventing identity theft
  • Staying safe online
  • Accessing fraud prevention and reporting resources on the Social Security Administration’s (SSA) website

Tips for next year

  • File your tax return on time. An extension to file a tax return doesn’t extend the time you have to pay.
  • Pay any tax you owe by the due date to avoid interest and penalties or explore alternate options like a payment plan if you can’t pay in full.
  • Learn more about how to get an identity protection PIN (IP PIN).

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
