Do I file an amendment for a W2 correction from Box 12 - Code C?

[cooldalmatian]

I have filed my tax return and already received my refund. My husband's employer sent a corrected W2 (received after filed) and the only difference is in Box 12. It is Code C and the amount increased  by 38.88. That is the only difference from the original. I realize this is tied to employer benefits (I think it is our vision insurance?); however it does not change our bottom line. Do I still need to file an amended return?

No.

The IRS says that you need to amend if:

• "You received a corrected tax form after filing (the "corrected" box is checked) and the new info changes your refund or tax due amount."

The tax tables change every $50, so that is likely reason that the $38.88 did not change your bottom line.

You are welcome!

My employer came back with a $100 difference coded C. Do I need to amend my tax return? I've already filed already.
