About Supplemental Funding Request Preparation and Submission


The Research.gov Supplemental Funding Request Submission System modernizes supplemental funding request preparation and submission capabilities by improving the user experience while also reducing administrative burden through an intuitive interface and expanded automated compliance checking. Awardees can submit a supplemental funding request in Research.gov for any award, regardless of which proposal submission system (Research.gov, FastLane, or Grants.gov) was used. Effective January 30, 2023 with implementation of the revised Proposal & Award Policies & Procedures Guide (PAPPG) (NSF 23-1), NSF has transitioned the preparation and submission of all new supplemental funding requests from FastLane to Research.gov. FastLane functionality for the preparation and submission of new supplemental funding requests is being decommissioned. Please see the FastLane Decommissioning page for details. For more information about supplemental funding requests, please see PAPPG Chapter VI.E.5.  

Although a Program Officer concurrence email is not required to be uploaded in Research.gov when submitting a supplemental funding request, NSF strongly recommends that the Principal Investigator (PI) or co-PI contact the NSF cognizant Program Officer before preparing and submitting a supplemental funding request for an award.
