The IRS sometimes issues a prior year EIC disallowance and you may not be aware of it due to not receiving notification by mail or if it is issued after you have received your refund (in a prior year). If you are continually receiving the rejection, Form 8862-Information To Claim Certain Refundable Credits After Disallowance is required in order to be able to e-file your return.
This form allows for an explanation of why you should be entitled to EIC after the IRS has disallowed it and alerts the IRS that more information is necessary to process the return.
