NIH SBIR/STTR Deadline Approaching: April 2026 Phase I Application Guide

What's Funded

• Phase I award size: Up to $316,219 for 6 months (SBIR); STTR is the same ceiling with a required nonprofit research partner
• Phase II follow-on: Up to $2,099,398 for 24 months — awarded based on Phase I success
• Fast-Track option: Submit Phase I and Phase II as one combined application to reduce total timeline
• Eligible research areas: Therapeutics, diagnostics, medical devices, digital health, behavioral interventions, basic science with commercialization path
• Non-dilutive: No equity exchange — unlike venture capital, NIH SBIR funding does not dilute ownership

Eligibility Requirements

• For-profit U.S. small business with 500 or fewer employees
• 51%+ owned and controlled by U.S. citizens or permanent resident aliens
• Principal Investigator primarily employed at the small business at time of award
• STTR additionally requires a formal agreement with a nonprofit research institution performing at least 30% of work
• Active SAM.gov registration required before submission
• Registered in NIH eRA Commons with an Authorized Organization Representative (AOR)

How to Apply — Step by Step

• Step 1 — Identify your NIH Institute: Visit sbir.nih.gov and use the matchmaker tool to find which Institute or Center (IC) best fits your technology area. Each IC has a program officer you can contact for pre-submission advice.
• Step 2 — Find the right Funding Opportunity Announcement (FOA): Search for "PA-24-185" (SBIR) or "PA-24-186" (STTR) on grants.gov — these are the parent FOAs for Phase I. Some ICs publish specialized FOAs with additional requirements.
• Step 3 — Verify registrations: Confirm SAM.gov is active, eRA Commons account exists, Grants.gov is registered with your UEI number. Allow 3–5 business days if not yet registered.
• Step 4 — Prepare the application package: Key components: Specific Aims (1 page), Research Strategy (6 pages for Phase I), Innovation, Approach, Bibliography, Budget with justification, team biosketches, commercialization plan, facilities description.
• Step 5 — Submit via Grants.gov: Submit at least 2 business days before the deadline to allow for system processing. NIH does not grant extensions for technical issues if submitted too close to the deadline.
• Step 6 — Track in eRA Commons: After submission, check eRA Commons for acceptance confirmation, Study Section assignment, and review scores (released approximately 3 months after the due date).

Tips to Strengthen Your Application

• Contact the IC Program Officer before submission — they can confirm fit and may provide informal feedback
• Frame the Specific Aims to clearly state the problem, your approach, innovation, and expected outcomes in one page — reviewers read this first
• Include preliminary data — even early-stage data dramatically improves competitiveness
• The commercialization plan must describe a realistic path to market: target customers, regulatory pathway, revenue model
• Budget must be detailed and justified — NIH reviewers will flag any item that appears unsupported
• A resubmission (A1) is allowed once if the first application (A0) is not funded — address all reviewer critiques explicitly
