thank you for responding. Yes, my employer has employees in multiple states including DE and NY. I called the DE Revenue number on my notice and they told me that the adjustment was done by the DE auditor because my W2 had DE withholding. When I moved in mid of 2022 to NY, i was a fulltime NY employee and also NY resident and did not do any remote work for DE. After speaking to my HR team i was told that they will not issue me a new W2 and the reason they withheld taxes is because some part of my bonus that was awarded in 2020(when i was working in DE) was vested in 2023 and that is why that portion is getting shown on the 2023 W2 as DE income. Is this the expected treatment of vested income and does it matter which year it was awarded? i am not sure if i can appeal the notice and get my refund back.
