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.
In the best-case scenario, your employer messed up your address or misspelled your name.
Worst case, your wages are off by thousands of dollars due to mistakes around the tax treatment of your employee benefits, including dependent care expenses and life insurance premiums.
