Taxpayer guide to identity theft

If you use an online application to do your taxes, you can now log in with your username, password and a third personal item like a phone number. Using all 3 will keep your identity and data safer.

Tax-related identity theft occurs when someone uses your stolen personal information, including your Social Security number, to file a tax return claiming a fraudulent refund.

If you suspect you are a victim of identity theft, continue to pay your taxes and file your tax return, even if you must file a paper return.

Know the signs of identity theft

You may not know you’re a victim of identity theft until you’re notified by the IRS of a possible issue with your return.

Be alert to possible tax-related identity theft if:

Take action if you are a victim

There are steps you can take if your Social Security number or other personal information is compromised.

Fraudulent returns

If you believe someone has filed a fraudulent return in your name, you can get a copy of the return. See Instructions for Requesting a Copy of Fraudulent Returns.

Dependents

If you e-file your tax return and get a message telling you that a dependent on your return has been claimed on another tax return or their own, or if you receive an IRS Notice CP87A, you’ll need to find out why someone else claimed your dependent. Learn more at What to Do When Someone Fraudulently Claims Your Dependent.

Data breach

Not all data breaches or computer hacks result in tax-related identity theft. It’s important to know what type of personal information was stolen.

If you’ve been a victim of a data breach, keep in touch with the company to learn what it is doing to protect you and follow the “Steps for victims of identity theft.” Data breach victims have the option to submit a Form 14039, Identity Theft Affidavit online, or by completing the fillable Form 14039 PDF , printing and then mailing or faxing the form to the IRS. Choose one option and submit the form if your Social Security number has been compromised and your e-filed return was rejected as a duplicate or the IRS instructs you to file the form.

Employment-related identity theft

If you believe someone has been using your Social Security number for employment purposes (as opposed to filing fraudulent tax returns for refunds in your name) see our Guide to employment-related identity theft.

Assigned an EIN not requested

If you've been assigned an Employer Identification Number (EIN) that you didn't request, you should first determine if someone acted legitimately on your behalf.

It's important for you to determine why the EIN was assigned to you before assuming you're a victim of identity theft. A third party may have requested an EIN on your behalf for a legitimate business purpose. What to do if you’re assigned an Employer Identification Number (EIN) you did not request.
