NIH might give you a two-week grace period on late applications. For details, see the Notice issued Dec 2014.
Examples of Reasons Why Late Applications Might Be Accepted
- Death of an immediate family member of the PD/PI (or MPI).
- Sudden acute severe illness of the PD/PI (MPI) or immediate family member.
- Temporary or ad hoc service by a PD/PI on an NIH advisory group during the two months preceding or the two months following the application due date. Examples of qualifying service include: participation in an NIH study section/special emphasis panel, NIH Board of Scientific Counselors, Program Advisory Committee, or an NIH Advisory Board/Council. Qualifying service does not include participation in NIH activities other than those involved in extramural/intramural peer review or NIH Advisory Council/Board service.
- Delays due to weather, natural disasters, or other emergency situations, not to exceed the time the applicant organization is closed.
- For PD/PIs who are eligible for continuous submission (http://grants.nih.gov/grants/peer/continuous_submission.htm), the late application policy applies to activities not covered under the continuous submission policy (i.e., other than R01, R21, and R34 funding opportunities that use standard due dates).
Examples of Reasons Why Late Applications Will Not Be Accepted
- Heavy teaching or administrative responsibilities, relocation of a laboratory, ongoing or non-severe health problems, personal events, participation in review activities for other Federal agencies or private organizations, attendance at scientific meetings, or a very busy schedule.
- Review service for participants other than a PD/PI or MPI, acute health issues or death in the family of a participant other than a PD/PI or MPI.
- Problems with computer systems at the applicant organization, problems with a system-to-system grant submission service, or failure to complete or renew required registrations in advance of the application due date.
- Failure to follow instructions in the Application Guide or funding opportunity announcement.
- Correction of errors or addressing warnings after 5 PM local (applicant organization) time on the application due date. Applicants are encouraged to submit in advance of the due date to allow time to correct errors and/or address warnings identified in the NIH validation process.
