Problem: The IRS - not eFile.com - rejected your Federal Income Tax Return because you must add Form 8862 to claim the Earned Income Tax Credit since you were not allowed to claim the credit in a previous Tax Year.
Solution: Sign into your eFile.com account and you should see the error message with a link that will bring you right to the Form 8862.
Otherwise, click federal taxes, review, then the "I'd like to see all federal forms" link, search for 8862, click the "Add form" button next to the Information To Claim Refundable Credits After Disallowance result, complete the screen, and click the green "Save" button at the bottom to save your changes.
In the event that you cannot or do not want to re-efile your return, please PRINT your return from your account, sign it, and MAIL it to the IRS. See printing and mailing instructions plus addresses based on your resident state. You may need to print, sign, and mail your State Tax Return to the State Tax Agency. Then, contact the IRS at 1-800-829-1040 and discuss your tax return in more detail.
