Grace period

  • The IRS considers returns that are re-filed electronically during the applicable time frame to be timely-filed returns.
  • The grace period starts at the time of the rejection and is never extended for weekends, holidays, or end-of-the-year cutoff.
  • If a rejected return cannot be retransmitted electronically, see Resubmitting electronically filed returns and extensions (FAQ).
  • The perfection period does not apply to payments. When the return is rejected on the due date, remove the date in the Requested payment date field in Screen ELF before you resubmit the return or extension. You must remit the payment through the Electronic Federal Tax Payment System (EFTPS). Refer to IRS Publication 4163 for more information.
