After you file

If the AGI you used was incorrect, the return will be rejected, if it has not already been rejected.  What is your e-file status?

If the return has been rejected you can correct the AGI and try to re-file it.  If you are unsuccessful in re-filing it, you can also try using zero as the AGI.  If zero does not work, then print, sign and mail the return.

 

 

If you used the wrong AGI, your e-file  be rejected.  When you get the rejection notice, correct it and re-file.
