I am new to NYC tax filing. I have a client who is employed by NYC, but I'm not sure how to figure out if he is required to file a form 1127. Would that be something that he needs to find out from his employer? Do the forms ever get filed on their behalf? His previous CPA didn't file it for him and he hasn't filed it for three years. And another question, can you claim the withholding on the W2 on the 1127 or is that only for the state return?
