Do I need to sign my 1040 when I mail in California State Tax Return? I electronically filed my 1040 to the IRS and it has been accepted.
I plan on mailing my state tax return. I know I need to sign the state tax return. I don't know if I have to sign the 1040 that I will turn in with my state tax forms. Since I electronically filed my 1040, it is not signed.
