I moved from New Jersey to Pennsylvania at the end of August. I notified the HR department of my employer but HR never notified the payroll department about the change of address. I got my 2023 W2 and it shows 12 months of NJ State tax withheld, not 8 months of New Jersey and 4 months of Pennsylvania. My employer is telling me that I need to file a part year return for NJ State and get a refund for the tax withheld from September to December. Conversely, I need to file a PA State tax return to report the wages and tax owed from September to December. They say I should get a refund from NJ State and would owe to PA State.
Does this sound correct? Do I need to get a corrected W2 from them?
