Very sorry for your loss. For the year that your spouse passed, you were able to file a joint return. For the next two years after that, you can file as a Qualifying Surviving Spouse if you have qualifying dependent children claimed on your return. That way you get the same standard deduction that would be allowed on a joint tax return. Have you entered the children as dependents in MY INFO?
