Is this allowed? My husband's employer paid us 3K in advance for a move in 2019 and I guess, forgot to add it to that W2 so they decided to throw it on 2023's w2 so they could reconcile their books. Is this legal? Shouldn't they have corrected the W2 for 2019 instead of adding it to this year, when it was not received and no taxes were taken out for it? We already asked them to correct the W2 but they have refused. I have been on the phone with the IRS for most of the day today and no one can seem to answer the question.
