Signatures are required when mailing in your forms. Take a look at your 1040 form.

However, before you mail your form, there
are a few possible reasons why you're getting a reject.
If
you:
- Filed late last year
after mid-November or your return was processed after that time—try entering 0.
- Amended your return
last year—make sure you’re using the
AGI from your original return, not the amended one. (If you only have a
1040X form, it’s on line 1, column A.)
- Rounded your AGI to
the nearest dollar—be sure to round up when it’s
50 cents or more and down when it’s 49 cents or less.
- Filed with your
spouse last year—you and your spouse have the
same 2016 AGI. (Don’t split the AGI amount or enter “0” for one of you.)
If you’re still having trouble, we suggest that you check
with the IRS to make sure that the copy of your return is the same as what they
have in their records. To do this, you can order a tax return transcript.
If you’ve tried everything and nothing works, you can
still file a paper
return by printing out copies of your
federal and state returns and mailing them. We’ll include File by Mail Instructions on where to send your returns and what forms, if any, you
need to include.
