SBIR Proposal Caps and Foreign Screening Will Reshape Innovation Funding

The SBIR and STTR programs are back after a six-month funding freeze, but the reauthorization deal between Senators Joni Ernst and Edward Markey comes with significant new rules that will force small businesses to rethink their proposal strategies starting in FY2027.
Mandatory Proposal Limits Are a First
For the first time in the program's 43-year history, agencies must impose proposal submission caps per small business. Each agency's SBIR program director will set the limits, which can be structured per fiscal year, per solicitation, or per topic area. Both SBIR and STTR applications count against the total cap.
Waivers exist but are deliberately narrow: agencies can grant topic-specific exemptions only for "time-sensitive and urgent" needs, limited to 5% of topics annually, requiring written justification and senior official approval within 15 days. Companies that previously submitted dozens of proposals across multiple agencies each cycle will need to be far more selective about which topics they pursue.
Foreign Risk Screening Gets Teeth
The bill establishes mandatory due diligence reviews covering cybersecurity practices, patent analysis, employee screening, and foreign ownership or financial ties. Applicants must disclose relationships with "foreign countries of concern," and affiliation with entities on federal restriction lists is grounds for denial. Denied applicants receive notice but aren't permanently barred — preserving due process while tightening security controls.
What Small Businesses Should Do Before Solicitations Open
Agencies are expected to publish first post-restart solicitations between April and May 2026, with NSF's rolling-submission SBIR program likely among the earliest to reopen. The authorization extends through September 2031, and the new Strategic Breakthrough Awards pathway offers up to $30 million over 48 months for companies with prior Phase II awards and matching private capital.
The immediate action: audit your proposal pipeline. With caps in place, every submission must count. Prioritize topics where you have the strongest technical differentiation and existing preliminary data. In-depth strategy guidance for the new SBIR landscape is available on the Granted blog.
