SBIR (Small Business Innovation Research) is a federal program that gives U.S. small businesses non-dilutive money to research and commercialize new technology. The government takes no equity and you repay nothing. To apply, register in SAM.gov, then the SBA Company Registry on SBIR.gov, then the portal of the agency that posted your topic. After that you submit a Phase I proposal. As of October 2026, SBA's no-waiver ceilings are $335,937 for Phase I and $2,239,578 for Phase II (SBIR.gov). The program is running again: Congress reauthorized it on , after a six-month lapse, and it now runs through (Crowell).

Which option is right for you?

Your first move depends on your situation. A for-profit startup with no federal registrations should open SAM.gov today. A nonprofit or university usually joins as an STTR research partner and does not apply as the lead.

Here is the reasoning behind each row. SAM.gov comes first because the SBA registry asks for your UEI. NSF suits beginners because a short pitch tells you whether you fit before you spend weeks writing. NIH's cycle repeats every year, so you can plan around it. DoD pays for very specific problems. Nonprofits are excluded because SBIR requires a for-profit applicant.

What Is SBIR (and STTR)?

SBIR and STTR are federal programs that fund small businesses doing R&D aimed at commercial products. STTR also requires a formal partnership with a nonprofit research institution. SBA coordinates both programs, and 11 federal agencies fund awards through them (SBIR.gov). Each agency writes its own topics, runs its own review and pays its own awards. That is why the process feels different at NSF, NIH and DoD.

Who is eligible

Per SBIR.gov's eligibility FAQ, the company must:

The three phases

Phase I tests feasibility. Phase II funds full R&D, and only Phase I awardees or Direct-to-Phase-II applicants can get it. Phase III is commercialization paid for with non-SBIR money, such as a government production contract or private sales. SBIR.gov describes Phase I as typically lasting 6–12 months and Phase II as about 24 months (SBIR.gov Apply).

The 2026 reauthorization (S. 3971) added a new Phase II "strategic breakthrough" award worth up to $30 million. It also expanded foreign-risk screening and set up future caps on how many proposals one company can submit (Wisconsin CTC). If you have ties to foreign investors, foreign partners or foreign-funded research, expect more disclosure forms than older guides describe.

How to Pronounce SBIR

Most people in the field say SBIR as one word, "ess-bur" (rhymes with "fur"). Some spell it out as "S-B-I-R." SBA doesn't publish an official pronunciation, so either is fine on a call with a program officer.

For example, an applicant might say, "We're applying for an ess-bur Phase I at NSF and an ess-tee-tee-are with a university partner." STTR is almost always spelled out letter by letter. Don't mix SBIR up with SBIRT, a healthcare term covered in its own section below.

How to Find SBIR Grants

You find SBIR grants by searching open topics on SBIR.gov, then confirming the details on the agency's own solicitation page. The agency version is the one that counts. The 11 agencies publish on different schedules, so a topic that closed last month may come back next cycle under a new number.

Steps to find a matching topic

  1. Go to SBIR.gov and open the topics and solicitations search.
  2. Filter by agency, and by status (open or pre-release). Pre-release topics are worth watching. At DoD, the pre-release window is when you can email the topic author with technical questions (DoD SBIR).
  3. Search keywords from your technology: the material, the sensor type, the disease area. Avoid generic words like "innovation."
  4. Open the full solicitation on the agency site and write down the closing date, the time zone, the award ceiling and the submission portal.
  5. Check fit. Does the topic ask for your exact capability, or something next to it? Topic-driven agencies such as DoD tend to reject "close enough" proposals.

A common mistake is relying on a third-party deadline calendar. After the 2025–2026 lapse, many calendars were out of date. Treat the agency's solicitation PDF as the only source for the deadline.

How to Get SBIR Funding (Step-by-Step)

To get SBIR funding, register in a fixed order, match one agency topic, then win Phase I before you compete for Phase II. Registrations can take weeks, so start them before you write anything.

The 6 steps

  1. Confirm eligibility. Check the for-profit, ownership, 500-employee and U.S. location rules against SBIR.gov's FAQ. SBIR.gov's registry also has an optional eligibility check as its first step (SBIR.gov Company Registration).
  2. Register in SAM.gov. On SAM.gov, choose Get Started under entity registration and pick Register Entity, not "Get a Unique Entity ID Only." Under purpose of registration, pick All Awards if any target agency awards SBIR as a contract (DoD often does). "Financial Assistance Awards Only" covers grants only. You need the UEI from SAM.gov before you can finish the SBA registration (SBIR.gov Apply). The full sequence is in our guide to Grants.gov vs SAM.gov registration order.
  3. Register in the SBA Company Registry on SBIR.gov. It takes four steps: an optional eligibility check, sign-in or account creation, company information (including your UEI), then ownership and contact details. When you finish, you get an SBC Control ID that works at all 11 agencies (SBIR.gov Company Registration). Save the registration PDF, because some agencies ask you to attach it.
  4. Register in the agency portal. NSF needs a Research.gov account with Login.gov (NSF 26-510). NIH needs eRA Commons accounts for the organization and the PI, plus Grants.gov. DoD needs a DSIP account.
  5. Pick one topic and win Phase I. Write to the solicitation, which the next section covers, and submit before the deadline.
  6. Plan Phase II and Phase III early. Phase II generally goes to Phase I awardees. Your Phase I final results become the evidence for Phase II, and real customer interest supports your Phase III case.

SBIR.gov's Apply page gives typical ranges of $50,000–$323,000 for Phase I and $650,000–$2.2 million for Phase II (SBIR.gov Apply). Inside those ranges, each agency and NIH institute sets its own caps. Some NIH institutes allow more for approved topics. The budget limit in your specific announcement is the number to use.

Common registration mistakes and fixes

How to Write an SBIR Grant Proposal

A competitive SBIR proposal follows the agency's template exactly. It answers the topic's technical objectives directly and pairs them with a believable commercialization plan. Reviewers score against the solicitation's criteria, so write to those criteria, not to a general pitch deck.

Writing steps

  1. Download the current solicitation and its instructions. For NSF that is NSF 26-510. For NIH it is the parent announcement plus the SBIR/STTR instructions. For DoD it is the release instructions and the component instructions. Old templates carry old page limits.
  2. Build an outline from the review criteria. Make each criterion a heading so reviewers can find your answer quickly.
  3. State the technical risk plainly. Phase I pays to answer "can this work?" Name the hypothesis, the specific objectives and the measurable go/no-go results.
  4. Write the commercialization plan. Cover customers, the market, competitors, the revenue model and the path to Phase III. NSF's Project Pitch asks about technical innovation, commercial potential and broader impacts before you're invited to write a full proposal (NSF Seed Fund).
  5. Build the budget and justification. Stay under the cap, which includes direct costs, indirect costs and fee. For STTR, show the 40%/30% work split clearly. NSF does not allow cost sharing (NSF 26-510).
  6. Gather the required attachments. Typical ones are biosketches, letters of support, the SBA registry PDF and foreign-disclosure forms.
  7. Do a compliance pass. Check page limits, font rules, file names and that every required section is present.

Example: matching a topic objective

Say a DoD topic asks for "a sensor that operates at -40°C with under 5 W power draw." A weak objective reads "develop an innovative low-power sensor." A strong one reads "demonstrate a prototype maintaining ±2% accuracy at -40°C at ≤5 W, measured in an environmental chamber by month 5." The second version quotes the topic's own numbers and makes them testable. (These values are illustrative only, not from a real topic.)

Pitfalls and fixes

How to Submit an SBIR Proposal

You submit through the sponsoring agency's own portal, not through SBIR.gov. SBIR.gov only issues your SBC Control ID and lists topics. Submit at least two business days early, because validation errors usually show up at the end.

Portal by agency

Portal by agency. Source: Grants.gov
AgencySubmission systemKey requirement
NSFResearch.govAn invited Project Pitch first. Login.gov sign-in. Decisions come about 6 months after submission (NSF Seed Fund)

Other agencies (DOE, NASA, USDA, EPA, etc.)Named in each solicitationCheck the solicitation's "how to apply" section

Submission steps

  1. Confirm that SAM.gov is Active and that the details match your SBA registry record (how to check SAM status).
  2. Log in to the agency portal and start the proposal under the exact solicitation or topic number.
  3. Enter your UEI and SBC Control ID, then upload each section in the required format.
  4. Run the portal's validation check. NIH ASSIST, Research.gov and DSIP all flag missing items before final submission. If you file through Grants.gov directly, see our Grants.gov Workspace guide.
  5. Have the authorized company official certify and submit. At DoD, a proposal that was started but never certified is not submitted.
  6. Save the confirmation and tracking number, and check for any error emails over the next 48 hours.

SBIR vs. SBIRT: Don't Confuse These Two

SBIRT is not a grant program. It stands for Screening, Brief Intervention, and Referral to Treatment, a public-health approach to substance use (SAMHSA). If you searched "how to do SBIRT" or "how to score SBIRT," you want SAMHSA's clinical guidance, not SBA.

Common pronunciation"ess-bur""ess-bert"

There's one place the two terms meet: SAMHSA itself funds SBIRT grants. Its FY 2026 notice is TI-26-005. Those are SAMHSA grants for health providers, not SBIR awards. A clinic searching for "SBIRT funding" should read that notice, not SBIR.gov.

Next steps

You can finish the first registration today and have a target topic picked by the end of the week.

Do it yourself today:

  1. Start or verify your SAM.gov entity registration and write down your UEI. Choose "All Awards" if DoD is a possible target.
  2. Create your SBA Company Registry record on SBIR.gov and save the SBC Control ID PDF.
  3. Pick one cycle. If NSF fits, submit a Project Pitch now. Pitches get a response in about 1–2 months (NSF Seed Fund), so the deadline is likely too close and is the realistic target.

FAQ

What is SBIRT screening?

SBIRT screening is the first step of Screening, Brief Intervention, and Referral to Treatment. A clinician uses a short validated questionnaire to estimate how risky a person's alcohol or drug use is (SAMHSA). The result decides whether the person needs no action, a brief conversation, or a referral to specialty care. It has nothing to do with SBIR funding.

How do you score SBIRT?

You score the screening tool, not SBIRT itself. With the AUDIT alcohol screen, the commonly cited positive cutoff for adults is 8 or higher. Lower cutoffs apply to some groups, such as 5 or higher for adolescent girls and older adults and above 0 during pregnancy (NIAAA, Alcohol Research: Current Reviews). Follow your clinic's protocol and SAMHSA guidance for the tool you use.

How do you use SBIRT?

Screen everyone in the setting with a validated tool. Then give a brief, motivational conversation to people at moderate or high risk, and refer people at severe risk to specialty treatment (NIAAA). Primary care, emergency departments and schools commonly use it. SAMHSA's materials cover how to set it up.

How do you pronounce SBIRT?

Most clinicians say "ess-bert," as one word. SBIR, the grant program, is usually said "ess-bur." The extra "T" is the quick way to tell which one someone means.
