You do not sign a W-2. But you do sign a tax return.
Look closely--the new "postcard size" Form 1040 is supposed to be two half pages--front and back--but when you print it out, both sides print on one page. Do you see the black arrow pointing to the words "Sign here" in the middle of the page?
You mean your 1040 tax return? You do not sign a W2. Sign the 1040 at the bottom of page 2.
How to mail a return from the Online version
When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS received the return. Don’t forget state.
Important! Mail Federal and State in separate envelopes and mail each year in separate envelopes.
