The IRS has created an Identity Theft Information Page
Your identity may have been stolen if you receive a letter from the IRS stating that …
… you filed more than one tax return.
… you have a balance due, refund offset or have had collection actions taken against you for a year you did not file.
and / or
… you received wages from an employer you have not worked for.
If you receive such a letter from the IRS and you suspect your identity has been stolen, respond immediately to the name, address, phone number or fax listed on the IRS letter or contact the IRS to determine if the letter is a legitimate IRS letter.
If you become the victim of identity theft outside of the tax system or believe you may be at risk due to a lost/stolen purse or wallet, questionable credit card activity or credit report, etc., you are encouraged to contact the IRS at the Identity Protection Specialized Unit, toll-free at 800-908-4490 so we can take steps to further secure your account.
The IPSU hours of Operation: Monday – Friday, 7 a.m. – 7 p.m. your local time (Alaska & Hawaii follow Pacific Time).
You will need to fill out the IRS Identity Theft Affidavit, Form 14039. Please be sure to write legibly and follow the instructions on the back of the form.
