Hi,
My previous employer had a payroll error where they continue to pay me after I no longer worked there (contract was until end of 2023, but kept getting paid at the start of 2024). I contacted them and they fixed their issue and asked me to repay the amount. I repaid the amount in the same year and was told they were going to update my W-2 for 2024, however when I received my corrected W-2, they did not adjust box 1 (wages, tips, and other compensation) and only adjusted boxes 3-6. I have yet to file as I don't understand why they did not adjust box 1.
Does this mean I will have to pay income tax on the overpaid amount, despite me not having "actually" received that amount?
