The NIH announced an updated policy for late submission of competitive applications. Specifically, it:
- Ends continuous submissions after Aug. 10, 2026.
- Modifies reasons considered for late submission.
- Prohibits fellowship, small business and international collaboration late applications.
Late application submission policy
The updated policy will go into effect for submission due dates on or after May 25, 2026.
To be considered under the late policy, investigators must submit their applications within two calendar weeks of the original due date, even if there is more than one reason for the delay. NIH considers those two calendar weeks the late application period. If an application due date extends to the next business day because it falls on a weekend or federal holiday, the late application period is calculated from that business day.
Applications can be submitted during the late application period if all of the following are true:
- One or more of the PD/PIs listed on the application encountered extenuating circumstances that led to the missed deadline.
- The PD/PI's extenuating circumstances are documented in the cover letter submitted with the late application
- The application is in response to a program that allows late submission. NIH will not accept late submission for:
- Fellowship (e.g., F30, F31, F32, F33, F99/K00) and small business (e.g., R41, R42, R43, R44, SB1, UT1, U44) applications that have the shortest processing time prior to review.
- Collaborative International Research applications (e.g., PF5, UF5).
- Any funding opportunity that states in the Key Dates section that late applications will not be accepted.
Investigators may also submit during the late application period, if within four calendar weeks before or after the due date, any PD/PI named on the application participates in:
- An NIH peer review study section or special emphasis panel.
- An NIH Board of Scientific Counselors, Program Advisory Committee or an NIH Advisory Board or Council.
This specific review service is the only pre-authorized reason for a late submission (i.e., automatically accepted once review service information provided in the cover letter is confirmed). Other types of NIH activities and services for other federal agencies or private organizations are not acceptable reasons for late submission.
