Why doesn’t my refund match my W-2?
The amount you see in box 2 of your W-2 is not necessarily your tax refund. That box shows how much was withheld from your pay. But like many others, you have a tax liability to pay tax to the government. So the refund you get back is the difference between how much you have to pay according to your filing status, tax bracket, number of dependents, credits and deductions, etc. and the amount that was withheld.
