Have a Tax Question? Ask a Tax Expert
Hi my name is Mark. I will be happy to help you with your question. First, I am very sorry for your loss.
You are probably correct that you will not have a tax liability if you had not had one in prior years and there were not a significant changes.
You can request an income transcript online from the IRS. This will contain all of the information that was reported to the IRS. This would provide the information needed to prepare the return.
