If filing late returns

[Alvsc]

Hello again,

If filing late returns should all the paper returns be sent in the same envelope or sent off separately.  

Thanks,

Late Bloomer

Use separate envelopes for each year or you risk that one or more of them will be overlooked by the human who opens the envelope.

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 certified mail so you will know the IRS/state received the return.

Federal and state returns must be in separate envelopes and they are mailed to different addresses.  Read the mailing instructions that print with your tax return carefully so you mail them to the right addresses.
