Would you file income taxes on your deceased spouse?

If they had taxable income this year, they will need to have their taxes filed. You being the spouse are probably the best to do it. I am in a similar situation, my grandmother and father passed away this year. I was the caretaker for both of them. I will be filing taxes for both of them. I am able to do it for both because I am the administrator of both estates. If your spouse passed away in 2010, the best thing to do is file as you guys normally did.
