Federal R&D funding for US small businesses flows primarily through SBIR and STTR, but NSF, NIH, DOE and DOD also offer direct research grants. This guide explains the main programmes and how to navigate the federal research funding landscape.
Federal R&D investment in the US exceeds $200 billion annually, making the US government the world's largest funder of research and development. Small businesses access this through SBIR and STTR (the dedicated small business programmes), but also through research partnerships with universities, direct agency grants, and cooperative agreements. Understanding the full landscape - not just SBIR - gives small businesses more routes to the funding they need.
SBIR (Small Business Innovation Research) and STTR (Small Business Technology Transfer) are the congressionally mandated set-asides for small business R&D. Over $4 billion annually is distributed through these programmes. SBIR is for small businesses working alone or with subcontractors; STTR requires a formal collaborative agreement with a university or federal laboratory, with at least 30% of the work at the research institution. For small businesses at the early stage of technology development, these are the first programmes to pursue - they're designed for exactly this situation and the application process, while demanding, is well-documented and supported.
NIH distributes over $40 billion annually in research grants - primarily to universities, hospitals, and research institutions, but with substantial flows to small businesses through SBIR and direct R&D grants. For biomedical, health technology, and life science businesses, NIH is the critical funder to understand. Beyond SBIR, NIH's R01 grants (the most prestigious research grant in biomedicine) and R21 exploratory grants are typically accessible to businesses with academic collaborators, not alone. Building an academic partnership is often the key that unlocks NIH funding beyond SBIR.
The Department of Energy's Office of Science funds basic research across a range of disciplines relevant to energy, physics, biology, and computing. ARPA-E funds transformational energy technology with a higher risk tolerance - awards of $500,000 to $5 million for novel approaches. The DOE's national laboratories are also potential partners for small businesses: several programmes facilitate small business access to national lab expertise and equipment, often as part of a DOE-funded project.
The R&D Tax Credit (Section 41 of the Internal Revenue Code) allows businesses to claim a credit of up to 20% of qualifying research expenditure against their tax liability. For early-stage companies with losses, the Protecting Americans from Tax Hikes (PATH) Act allows the R&D credit to offset payroll taxes - up to $500,000 per year. This is one of the most underused tax benefits for technology companies. SBIR-funded research expenditure can also qualify for the credit, though the interaction of grants and credits requires care - your CPA needs to know this area.
