The later-of-two-dates rule for a paper return
Postmark the paper return by the later of the return due date, including extensions, or 10 calendar days after the IRS rejection notice.
Key takeaways
- Electronic resubmission window: If your return is rejected at the end of the filing season, you have 5 days to correct any errors and resubmit your return electronically, according to Taxpayer Advocate Service.
- End-of-season paper fallback: If you can’t resubmit your return electronically and need to file a paper return at the end of filing season, it must be postmarked by the return’s due date or within 10 calendar days of the IRS notifying you that your e-file was rejected – whichever is later – to be considered on time, according to Taxpayer Advocate Service.
- Scope limitation: The five-day electronic resubmit note applies specifically to rejections at the end of the filing season. The paper filing rule compares the return’s due date (including extensions) against 10 calendar days after the rejection notice.
- Action step: Record the IRS rejection notice date on the client file immediately. Calculate the later of the return due date or 10 calendar days after that notice date to determine the final postmark deadline for a paper filing.
When the IRS rejects an electronic return, the Taxpayer Advocate Service states that you haven’t filed if the IRS rejects your return according to Taxpayer Advocate Service. This status requires you to determine the correct deadline for a paper submission. The Internal Revenue Service provides the specific rule for this scenario. To timely file a paper return after an electronic return was rejected, your paper return must be postmarked by the later of the due date of the return (including extensions) or 10 calendar days after the date the IRS gives notification that it has rejected your electronic return according to Internal Revenue Service.
This rule compares two specific dates. The first date is the due date of the return, which includes any extensions. The second date is 10 calendar days after the date the IRS gives notification that it has rejected the electronic return. You must identify which of these two dates is later. If the due date of the return is later, the paper return must be postmarked by that due date. If 10 calendar days after the rejection notice is later, the paper return must be postmarked by that later date.
Do not assume the 10-day period is the only deadline. The rule explicitly uses the later of the two dates. If the return’s due date is further in the future than 10 days after the rejection notice, the due date controls. If the rejection notice arrives late in the filing season, the 10-day period might extend past the original due date. In that case, the 10-day period controls.
Illustrative example of comparing the two dates
Suppose the return due date falls on day 15. The IRS rejection notice falls on day 10. Adding 10 calendar days lands on day 20. Day 20 is later than day 15, so the paper postmark deadline is day 20. Suppose instead the notice falls on day 4. Adding 10 calendar days lands on day 14. Day 15 is later than day 14, so the due date controls. These day counts are illustrative only.
The IRS explanation of the later of the two dates
The Internal Revenue Service outlines the specific timing requirement for paper filings that follow a rejected electronic submission. This rule establishes a dual-date comparison rather than a single fixed deadline, according to Internal Revenue Service. The first date is the original due date of the return, which includes any extensions that may have been granted. The second date is calculated by adding 10 calendar days to the specific date the IRS provides notification of the rejection. The postmark must meet the later of these two dates to be considered timely.
It is important to note that the 10-day window is not a standalone deadline that applies regardless of the original filing date. The notification date from the IRS is the critical anchor for the second date in this calculation.
The separate five-day electronic resubmit note
The Taxpayer Advocate Service page titled "Return Rejected - TAS" provides a specific electronic resubmit rule for rejections that occur at the end of the filing season. If your return is rejected at the end of the filing season, you have 5 days to correct any errors and resubmit your return electronically, according to Taxpayer Advocate Service. This five-day window applies specifically to the electronic correction and resubmission process during that period. It is distinct from the general paper filing deadline discussed in other sections of this guide.
Before another electronic submission, review signature rules before you e-file.
If you can’t resubmit your return electronically and need to file a paper return at the end of filing season, it must be postmarked by the return’s due date or within 10 calendar days of the IRS notifying you that your e-file was rejected – whichever is later – to be considered on time, according to Taxpayer Advocate Service. This sentence ties the paper filing deadline to the same end-of-season scenario. The phrase "whichever is later" indicates that the 10 calendar days do not replace the due date but may extend the deadline if the notice arrives late.
The 2026 Form 1040 transmission dates
The Internal Revenue Service publishes a specific schedule for the Tax year 2025 / processing year 2026 Form 1040 MeF due dates.

| Event | Date |
|---|---|
| Last date for retransmitting rejected timely filed returns | April 20, 2026 |
| Last date for retransmitting rejected, late, or returns on extension from Form 4868 | October 20, 2026 |

Note that the five-day electronic resubmit rule mentioned in other contexts applies specifically to rejections at the end of the filing season and is distinct from these fixed calendar dates. The dates listed here are the operational boundaries for the MeF system for this specific processing year.
