- When an e-filed return or extension is rejected, the IRS provides a Transmission Perfection Period, or look-back period, to correct the filing and retransmit it. If the previously rejected filing is accepted by the IRS within the perfection period, it will be considered to have been received on the date of the first rejection that occurred within the period. Extensions for individuals are typically granted 5 calendar days. For more details on the perfection period, see IRS Pub. 4164. Check your state’s website to verify whether they allow the same perfection period as the IRS.
