<prompt> Human: I worked for 2 companies in 1 year. 1 company got bought out by the other by the end of February. I did not expect the old company to send me a W2 form. I already went to an accountant a couple weeks ago and got my money back from the government. Is it to late to file for another tax return? Can I just go back with the new W2 form?  <response>: What you have to do is file an amended tax return. You have to combine all income on one return, and file it properly.
