Sometimes your employer can derail your tax season.
Earlier this year, employees received their Form W-2 from their employers, detailing how much they earned, what they contributed to any retirement plan and how much was withheld in taxes.
You were supposed to get your W-2 by Jan. 31.
Early bird filers tend to snap up this information and submit their returns as soon as possible.
Once in a while, those motivated taxpayers get a surprise in the mail sometime later: a corrected W-2 from their employer.
The upshot: You may have filed a return with the wrong data and may have to amend it.
