In April 2026, the FY2027 President's Budget request proposed cutting NSF by 55% and NASA's science budget by nearly half. Those numbers were public months before any solicitation changed. Most founders applying to those agencies never saw them.
That is the case for adding congressional budget justifications to your grant strategy. A congressional budget justification (CBJ) is the detailed document every federal agency submits to Congress each year explaining its budget request, program by program. It shows which offices are growing, flat, or declining before the fiscal year starts, and it is free.
This guide covers the 3 sections of a CBJ that actually matter, a 45-minute reading process, and the current budget signals for the 6 agencies that fund most startup R&D.
What is a congressional budget justification?
A congressional budget justification is the document a federal agency submits to Congress alongside the annual President's Budget request. It explains, program office by program office, how much money the agency wants for the coming fiscal year, what it spent before, and what it plans to fund. Every agency publishes one, publicly and for free.
The request typically lands between February and April. The FY2027 justifications became public in April 2026, covering the fiscal year that starts October 1, 2026.
These documents run 100 to 500+ pages per agency. Almost nobody outside appropriations staff reads them, which is exactly why they are useful.
Your competitors for an SBIR award are reading the solicitation. Almost none of them are reading the budget document that determines whether the program behind that solicitation grows or shrinks.
You do not need to read all 500 pages. You need 3 sections and about 45 minutes per agency. More on that below.
Why agency budget trends decide your SBIR pool size
Here is the mechanical link most founders miss: SBIR budgets are not set by the agency's SBIR office. They are a fixed percentage of the agency's extramural R&D budget.
Agencies with over $100 million in extramural R&D must set aside 3.2% for SBIR. Agencies with over $1 billion must also set aside 0.45% for STTR, a much smaller group that includes NIH, DOD, DOE, NASA, and NSF.
Congress reauthorized both programs through 2031 on April 13, 2026, and left those percentages unchanged. When an agency's R&D budget shrinks 20%, its SBIR pool shrinks roughly 20% with it. No agency discretion involved.
That reauthorization date matters for another reason. SBIR and STTR lapsed on September 30, 2025 and stayed lapsed for six and a half months, the longest gap in the programs' history. Agencies paused solicitations.
Founders who tracked budget and authorization documents saw that risk building in mid-2025. Founders who only tracked solicitation pages found out when the solicitations disappeared.
The new law also created Strategic Breakthrough awards of up to $30 million over 48 months with required 1:1 matching. That program appeared in legislative text and budget documents well before any agency published guidance. Reading upstream documents is how you get quarters of lead time instead of days.
The request is not the budget (and the gap is the signal)
The single biggest mistake in reading budget documents: treating the President's request as the actual budget. It is an opening bid. Congress writes the checks.
FY2026 is the cleanest example in years. The FY2026 request proposed cutting NIH by roughly 40% and NSF by more than half. Congress rejected nearly all of it.
NIH ended FY2026 enacted at $47.5 billion, up 1%. NSF took a 3% cut, not 57%. Per the Congressional Research Service, all five major research agencies were enacted above the President's request.
The FY2027 request, released in spring 2026, proposes many of the same cuts again per the agencies' own FY2027 justifications: NIH at $41.4 billion (about 13% below FY2026 enacted), NSF at $4 billion (down 55%), NASA science down $3.4 billion. If history repeats, Congress restores much of it. But "Congress will probably fix it" is not a grant strategy.
So read two numbers, not one. The enacted budget tells you the real trajectory: growing, flat, or declining. The request tells you whether the program is contested. A contested program can survive with flat funding and still burn you through delayed solicitations, skipped award cycles, and program officers who cannot commit to timelines.
Classify every target agency on both axes. Flat and uncontested is a calmer bet than flat and contested, even though the enacted dollars look identical.
The 3 sections of a CBJ that matter
Skip the appropriations language, the object class tables, and the performance metrics. For grant strategy, three sections carry all the signal.
1. Program-level budget tables
Every CBJ includes summary tables with three columns: prior year actual, current year enacted, and budget year request. This is where you trace your specific program office, not the agency topline.
The topline hides the story. DOE's enacted R&D funding moved just -0.4% to $21.0 billion in FY2026, per the Congressional Research Service. But inside the FY2027 request, DOE's Office of Science faces a 15% proposed cut for the second straight year, and the request cuts one of EERE's reorganized program pillars by 88% and another by 93%. A founder targeting EERE and a founder targeting DOD-adjacent DOE work are living in different budget realities under the same topline.
2. Narrative justifications
Next to every budget number is prose explaining what the agency told Congress it will fund. This language is a gift for proposal writing. Agencies fund what they promised Congress they would fund, and program officers are evaluated against those commitments.
Pull the recurring phrases for your program area and mirror them in your proposal's significance section. If the narrative emphasizes domestic manufacturing capacity or AI-enabled diagnostics, a proposal framed in that exact language aligns with what the program office already justified to appropriators.
3. New programs, terminations, and reorganizations
CBJs announce structural changes before they happen. The FY2027 NIH request proposes consolidating NIAAA and NIDA into a single new institute and eliminating 3 of the remaining 21 institutes and centers. Whether or not Congress agrees, any founder targeting those institutes should be watching that fight, because review panels, program officers, and funding lines all move when institutes merge.
New program proposals are the opportunity side. A program named in a budget request this spring is often 6 to 12 months from its first solicitation. Showing up in cycle one usually means facing a fraction of the applicant pool that cycle three draws.
How to read a congressional budget justification in 45 minutes
Here is the exact process, timed per agency.
- Find the document (5 minutes). Go to the agency's budget office page directly, not a search engine. The table below has locations for the 6 major agencies.
- Open the summary budget table (5 minutes). Look for "Budget Authority by Program" or similar in the front matter. Skip everything before it.
- Trace your program office across 3 years (10 minutes). Write down prior year actual, current year enacted, and budget year request for your specific office. Compute the two percentage changes.
- Read your program area's narrative (15 minutes). Extract 5 to 10 recurring priority phrases. These go into your proposal language file.
- Scan for structural changes (5 minutes). Search the PDF for "new," "termination," "consolidation," and "realignment." Note anything touching your program office.
- Classify and move on (5 minutes). One line per agency: growing, flat, or declining on enacted dollars, plus a contested flag if the request proposes a cut over 10%.
Six agencies at 45 minutes each is a 4.5-hour quarterly exercise. That is the entire cost of adding a budget layer to your grant strategy.
A worked example: choosing between DOE, DOD, and NSF
Take a fictional 12-person startup with a grid-scale flow battery prototype, deciding where to aim its next 2 applications. All three agencies plausibly fit. The budget documents split them apart.
DOE EERE: enacted funding survived FY2026 nearly flat, but the FY2027 request cuts the relevant reorganized pillars by 88% to 93%. Classification: flat but heavily contested. Real risk of delayed or shrunken solicitation cycles even if Congress restores the money.
DOD: FY2026 enacted R&D landed largely at the requested level, and the administration is explicitly shifting federal R&D toward defense. Classification: growing and uncontested. A dual-use grid resilience framing targets the budget current instead of fighting it.
NSF: enacted down 3% in FY2026, requested down 55% in FY2027. Classification: declining and heavily contested, though Congress rejected the same cut last cycle.
The fictional founder's move: lead with the DOD application, keep NSF as the second shot because Congress has defended it before, and hold EERE until FY2027 appropriations resolve. Same company, same technology, but the sequencing came entirely from budget documents. That is 45 minutes per agency changing which application gets written first.
Where to find each agency's budget justification
| Agency | Where the CBJ lives | FY2026 enacted signal | FY2027 request signal | SBIR pool relevance |
|---|---|---|---|---|
| NIH | NIH Office of Budget (officeofbudget.od.nih.gov), per-institute volumes | $47.5B, up 1% | $41.4B, down ~13%; institute consolidations proposed | Largest civilian SBIR funder; pool tracks extramural R&D |
| NSF | NSF budget request pages (nsf.gov) | Down 3% to ~$8.75B | $4B, down 55%; one directorate zeroed out | America's Seed Fund sized by agency R&D budget |
| DOE | CFO budget justification pages (energy.gov) | R&D funding $21.0B, down 0.4% | Office of Science down 15%; EERE pillars down 88-93% | Office-level trends decide topic availability |
| DOD | Comptroller budget materials (comptroller.war.gov), per-service volumes | R&D enacted near request | R&D priority shifting toward defense programs | Largest SBIR program overall; component-level reading required |
| NASA | NASA budget documents (nasa.gov) | Roughly stable | Science down $3.4B, nearly half | Science cuts flow into research-adjacent SBIR topics |
| USDA | Per-agency explanatory notes (usda.gov) | AFRI enacted at ~$435M | Request cuts USDA roughly 19% | Small SBIR pool; NIFA trends matter for ag-tech |
Frankly, the DOD volumes are the hardest read. The budget is split across services and defense agencies, and the document set runs thousands of pages. Start with the component that owns your topic area (Air Force, Army, Navy, DARPA) rather than the department-wide summary.
How budget signals should change your grant strategy
Three decision rules turn classifications into portfolio moves.
Growing and uncontested: weight it up. Apply earlier and more often. Growing budgets mean new topics, more awards per cycle, and program officers under pressure to obligate funds.
Contested: diversify and sequence. Do not abandon a contested agency, especially one Congress has defended before. But never let it be your only application, and sequence it behind a stabler bet. A contested program is a timing risk even when the dollars survive.
Declining and uncontested: demand a reason. A program that is shrinking with no congressional fight over it is being wound down on purpose. Apply only with exceptional fit, and have a named backup program before you start writing.
The deeper point: single-agency grant plans are fragile in contested cycles. In our work building multi-agency roadmaps at Cada, across 100+ proposals and 30+ agencies, budget trajectory is one of the scored factors that decides which programs make a company's portfolio and in what order. One document per agency per quarter is enough to keep that scoring current.
Two honest limits. A CBJ is a leading indicator, not a guarantee: appropriations can land months late, and continuing resolutions freeze prior-year levels in ways that mute every signal. And program-level details can shift inside a stable topline, so the office-level read matters more than any headline number.
Get the budget read without the 500 pages
If tracking 6 agencies' budget documents each quarter is not where your time should go, that is the part we do for you. Cada reads the congressional budget justifications behind every grant strategy we build, and budget trajectory is a scored input in every multi-agency roadmap.
Want the shortcut? Ask for a free budget trend briefing on your 2 or 3 target agencies: a one-pager with each program office's trajectory, contested-or-not status, and what it means for your application timing. No pitch, no obligation, nothing to pay.
If you want the full picture, a roadmap consultation folds these signals into a scored, sequenced grant portfolio for your company.
