The U.S. Senate passed the Small Business Innovation and Economic Security Act by voice vote on March 3, unlocking more than $4 billion in annual federal R&D funding that had been frozen for five months. The bipartisan bill, brokered by Senators Joni Ernst (R-Iowa) and Edward Markey (D-Mass.), reauthorizes the Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs through September 30, 2031.
The programs expired on September 30, 2025, cutting off funding across 11 federal agencies and leaving more than 3,700 small businesses without access to grants that many depend on for product development and commercialization. The five-month lapse marked the longest disruption in the programs’ 40-plus year history.
What the New Bill Changes
The reauthorization extends both programs for six years and introduces several structural changes. The most significant is a new “strategic breakthrough” award category worth up to $30 million per company. Agencies with SBIR budgets exceeding $100 million must allocate 0.5% of their budgets to these larger awards, which come with a 48-month performance period and require 100% matching funds from the recipient.
Standard Phase I awards remain in the $150,000 to $250,000 range, while Phase II awards continue at $750,000 to $1 million. The bill also drops a previously proposed lifetime funding cap that had drawn opposition from small business advocates. Instead, individual SBIR office directors at each federal agency will set annual limits on how many proposals a single company can submit.
New Protections and Requirements
The legislation strengthens due diligence standards designed to prevent foreign espionage, a concern that had stalled earlier reauthorization attempts in both chambers. New security screening measures target applicants with ties to foreign governments of concern, addressing a key Republican priority that had been a sticking point in negotiations throughout 2025. It also expands the types of funding available to small innovators by mandating I-Corps commercialization training and adding cybersecurity assistance through the Technical and Business Assistance (TABA) program.
Additional provisions simplify Phase III contracting, allow small businesses to select independent technical advisors, and limit excessive proposal documentation requirements that had historically burdened smaller applicants.
What Happens Next
The bill now moves to the House of Representatives for consideration. The House had previously passed a separate one-year clean extension (HR 5100) in September 2025, but that measure stalled in the Senate. With the bipartisan Ernst-Markey compromise now passed, House leadership faces a decision on whether to accept the Senate’s six-year version or push for amendments.
The National Small Business Association and the Small Business Technology Council both endorsed the Senate bill, calling it a critical step toward restoring capital access for innovation-driven small businesses. During the five-month lapse, multiple agencies had paused new SBIR solicitations, and some small businesses reported laying off research staff or halting product development entirely.
For founders and small business owners in R&D-intensive sectors like biotech, clean energy, advanced manufacturing, and defense technology, the programs represent one of the largest non-dilutive funding sources in the federal government. Unlike venture capital, SBIR and STTR grants do not require giving up equity.
If the House passes the bill without changes, the legislation would head directly to the President’s desk for signature, potentially restoring full program operations within weeks.
