Here’s a thought to warm the Grinch’s heart: while you’re focused on the holiday season, identity thieves are thinking about how to steal your information. One of the ways they try to do that is by filing a fake tax return using your information — like your Social Security number — to get a tax refund. You may only find out about it when you get a letter from the IRS. Or when you file your return, only to hear from the IRS that someone else already did. That’s tax identity theft, a problem we hear more about each year. Tax identity theft also happens when someone uses your Social Security number to get a job or claims your child as a dependent on a tax return.
