NIH just announced that there will be no April 5, 2026, deadline. It is now stated at the top of their seed.nih.gov website:
NIH has no active Small Business Innovation Research (SBIR) or Small Business Technology Transfer (STTR) Notices of Funding Opportunity (NOFOs); therefore, there is no April 5, 2026 receipt date (see NOT-OD-26-006). Any future NOFOs will be forecasted at Grants.gov prior to opening for applications.
At this point, we can only assume the next deadline will be Sept 5th. We will continue to keep you posted when the program is reauthorized and NIH releases its omnibus.
