Problem: The IRS - not eFile.com - rejected your Federal Tax Return Extension because the Spouse's prior year Adjusted Gross Income - AGI - or PIN is incorrect.
Solution: Sign into your eFile.com account, click on My Return, and continue through the checkout. Once you reach the AGI or PIN section, make sure you entered the correct AGI or PIN. Once you have corrected this, continue with your re-eFile process. You can re-eFile your return at no additional charge as many times as it takes to get it accepted. If you still face issues, trying entering "0" as your prior year AGI.
In some cases, the IRS rejects incorrectly. In that case, go to "My Account" in eFile.com and download, sign, print, and paper file your return via mail or call the IRS: 1-800-829-1040.
