Hello,
I received sign-on bonus in 2023 when I joined some company. As I left that employer before one year, I returned a partial amount of bonus in Oct. 2024. I got a corrected W2 (W2c) from the employer with only boxes 3, 4, 5 and 6 updated. I got refund for extra medicare/ss tax from the employer. Now, when I use TT desktop to amend return for 2023, as box 1 is not changed, TT shows an additional tax liability for federal tax. How's that possible?
In addition, I have few other questions:
a) Is amending 2023 is the right thing to OR should I claim a credit on 2024 return under IRC 1341?
b) As box 1 is not updated in W2c, is it a mistake from employer and I should seek revised W2c with box 1 updated?
c) If amending return is advised, can I just amend the return with revised figures for box 1 on my own even though W2c from employer doesn't revise that?
d) Can I assume the same revised figures (i.e. W2 wages - returned bonus amount) for state wages as well even though W2c doesn't have any box updated for state?
Would appreciate your responses. Thanks.
