How does someone steal your tax refund?
Armed with little more than your name, birthdate and Social Security number, a crook can file a fraudulent tax return and collect a refund. Then, when you go to file your legitimate return, the IRS blocks you because its records show your return has already been filed.
How can tax identity theft occur?
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.
