Grace period
- The IRS considers electronic returns re-filed during the applicable time frame as timely-filed returns.
- The grace period begins at the time of the rejection and is never extended for weekends, holidays, or end-of-the-year cutoff.
- The perfection period doesn't apply to payments. When the return is rejected on the due date, remove the date in theRequested payment datefield in the ELF screen before you resubmit the return or extension. You'll need to remit the payment through the Electronic Federal Tax Payment System (EFTPS). Refer to IRS Publication 4163 for more information.
