Solved: Re: If employee sent out correct W2 form with excessive ssn tax withheld but they returned it to me, do I still need to file amended tax return?

How long do the employer have to send out a corrected W2?

No. Unless somehow you claimed the excess Social Security tax on your return. Check 1040 Schedule 3 line 11 for it. Then Schedule 3 goes to 1040 line 31.

No, the previous w2 form has the matched ssn and medicare tax withheld, so I did not claim any excessive ssn tax in the tax return I already got. So if irs updates the w2 tax information with my tax transcript, I do not need to file my amended tax return, right?

Thank you!
