SBIR/STTR Reauthorization Bill Presented to the President — April 14 Deadline

The final step is now underway. On April 2, 2026, the Small Business Innovation and Economic Security Act (S. 3971) was formally presented to the President of the United States. This starts the constitutional clock: the President now has ten days (excluding Sundays) to sign the bill, veto it, or take no action. The bill’s presentment was confirmed by the official Congressional record on Congress.gov.

How the Ten-Day Rule Works

Under Article I, Section 7 of the U.S. Constitution, when a bill is presented to the President, one of three things can happen:

1. The President signs the bill. It becomes law immediately upon signature.

2. The President vetoes the bill. It returns to Congress, where a two-thirds vote in both chambers is required to override the veto. Given that S. 3971 passed the Senate unanimously and the House by a 345–41 margin, an override would be virtually certain.

3. The President takes no action. If ten days pass (excluding Sundays) while Congress remains in session and the President has neither signed nor vetoed the bill, it becomes law automatically without a signature. This is known as an unsigned enactment.

The only scenario in which the bill would not become law is a pocket veto — where Congress adjourns before the ten-day window expires and the President has not signed. However, Congress is back in session, which means a pocket veto does not apply in this case. Additionally, the overwhelming bipartisan support (345–41 in the House, unanimous in the Senate) makes a standard veto politically impractical, as Congress would almost certainly override it.

Why the Bill Has Not Yet Been Signed

As we reported in our March 26 update, the President stated in early March that he would not sign any new legislation until Congress passes the SAVE America Act, a separate bill that would impose new proof-of-citizenship requirements for voter registration. The SAVE America Act has stalled in the Senate, creating a broader legislative standoff that has delayed presidential action on several bipartisan bills — including S. 3971.

S. 3971 itself has nothing to do with the SAVE Act dispute. It passed with near-universal support across both parties and both chambers. The delay in signing is entirely a product of the broader standoff, not any substantive objection to the SBIR/STTR reauthorization.

Regardless of whether the President signs the bill or allows it to become law through the ten-day rule, the practical outcome is the same: SBIR and STTR programs will be reauthorized through September 30, 2031, and agencies will be able to begin issuing new solicitations.

What This Means for the Timeline

Agencies have been staging their solicitation pipelines throughout the six-month lapse and are prepared to move quickly once authorization is formally restored. The Department of Defense is best positioned to publish first, with pre-solicitation topic lists already refreshed. NIH, NSF, and other agencies are expected to follow within weeks.

What Applicants Should Do Right Now

With enactment now days away rather than weeks, preparation is no longer optional — it is urgent. Companies that are ready to submit when the first solicitations open will have a meaningful competitive advantage after six months of pent-up demand.

Finalize your proposal materials. Have your Project Pitch (NSF), Specific Aims page (NIH), technical narrative, budget justification, and biographical sketches ready to submit. DoD solicitations could open within days of enactment.

Audit your foreign affiliations. The expanded security screening requirements in S. 3971 mean that connections to entities on any of the eight specified federal watchlists could result in a denied application. Conduct an internal review of ownership, personnel affiliations, investment relationships, and technology licensing agreements before your next submission.

Plan your proposal submissions strategically. Per-company proposal caps take effect in FY2027. Start identifying your highest-priority agencies and topics now so you can allocate your limited submissions effectively.

Evaluate Strategic Breakthrough Award eligibility. If your company holds at least one prior Phase II award and can demonstrate 100% matching funds, this new pathway offers awards of up to $30 million with a 48-month performance period. Begin modeling your matching fund strategy and engaging with potential investors and non-SBIR government program offices.

Monitor agency communications closely. Solicitation windows may be compressed as agencies work to make up lost ground before the fiscal year ends on September 30, 2026. Response deadlines may be shorter than in previous cycles.

The Bottom Line

The SBIR/STTR reauthorization is now in its final procedural stage. S. 3971 has been formally presented to the President, and the constitutional ten-day clock is running. Whether the President signs the bill or it becomes law automatically on April 14, the outcome is the same: the most significant overhaul of the SBIR/STTR programs in over a decade will take effect, restoring more than $4 billion in annual innovation funding for American small businesses.

The six-month freeze is nearly over. The companies that prepared during the lapse will be the ones best positioned to compete when solicitations reopen.
