Yes. You now have to print and mail prior year returns. 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 or State received the return. Mail federal and state in separate envelopes.
You mail Federal to the IRS.
And mail each state to the right state. And some states want a copy of the federal attached.
