IRAP vs. SBIR: The Cross-Border Funding Comparison for Tech Startups

IRAP and SBIR are the flagship R&D grant programs in Canada and the US, respectively. IRAP reimburses up to 80% of eligible salaries on approved projects (up to $10M CAD). SBIR awards fixed grants of $150K-$315K USD (Phase I) and up to $2.1M (Phase II) through competitive solicitations. A company with entities in both countries can apply to both programs simultaneously -- they fund different legal entities performing work in different jurisdictions.

No side-by-side comparison of these programs exists anywhere on the internet. We work in both systems, so here it is.

The core difference in 30 seconds

IRAP is relationship-driven. You get assigned an Industrial Technology Advisor (ITA) who co-develops your proposal with you. The success rate at the formal proposal stage is high (~70-80%) because the ITA filters and shapes your project before it's submitted.

SBIR is competition-driven. You respond to a published solicitation, write a proposal independently, and anonymous reviewers score it against other submissions. Success rates are 15-25%. But the awards are larger and the validation signal is stronger.

Think of it this way: IRAP is like having a coach who helps you train for the game. SBIR is the game itself.

Side-by-side comparison

How the IRAP application process works (and why it's different)

The biggest structural difference between IRAP and SBIR isn't the money. It's the ITA.

When you apply to IRAP, you don't submit a proposal into a black box. You call the NRC, get assigned an Industrial Technology Advisor, and that person becomes your de facto R&D consultant. There are 250+ ITAs across Canada, each with deep technical and business backgrounds.

Your ITA helps you scope the project, refine the technical approach, build the budget, and shape the proposal before it reaches the review committee. If your project isn't a fit, the ITA tells you before you waste time on a formal submission. This is why IRAP's formal-stage success rate is so high -- the weak projects never make it to that point.

SBIR has no equivalent. You read a solicitation, write your proposal, and submit it to anonymous reviewers. Program officers at some agencies (NSF in particular) will take calls and give informal guidance, but nobody co-develops your submission with you. You're on your own.

For first-time grant applicants, this distinction matters a lot. IRAP's guided process is genuinely less intimidating. SBIR's competitive model rewards proposal-writing skill almost as much as technical merit, which is why first-time applicants have a 75-80% rejection rate.

Stacking IRAP with SR&ED

If you're running a Canadian R&D operation, IRAP and SR&ED (Scientific Research and Experimental Development) tax credits are designed to work together. Most companies that receive IRAP also claim SR&ED.

Here's how the stack works:

• IRAP reimburses 80% of eligible salaries during the project (cash in hand while you're doing the work)
• SR&ED provides a tax credit after your fiscal year on eligible R&D expenditures (retrospective)
• The catch: IRAP amounts reduce your SR&ED-eligible expenditures dollar-for-dollar. You can't claim SR&ED on expenses IRAP already reimbursed

Even with the reduction, the combined offset can exceed 60% of total R&D costs. For a CCPC (Canadian-Controlled Private Corporation) with the enhanced 35% refundable SR&ED rate, the math is strong.

The total government assistance cap is 75% of eligible project costs across all programs. You won't hit that ceiling in most cases, but it's worth knowing it exists.

Can you apply to both IRAP and SBIR?

Yes. If your company has entities in both countries, you can apply to both programs. Not for the same work -- for complementary workstreams in each jurisdiction.

Entity structure

The typical setup for cross-border companies:

• Canadian entity (ideally a CCPC for maximum SR&ED rates) applies to IRAP. Canadian-based team does Canadian R&D.
• US entity (incorporated in the US, 51%+ US citizen/PR ownership) applies to SBIR. US-based team does US R&D.
• Parent structure varies -- sometimes sister companies under a common holding company, sometimes a Canadian parent with a US sub (or vice versa)

The IRAP entity doesn't need to be a CCPC to qualify for IRAP itself -- foreign-owned Canadian subsidiaries are eligible. But CCPC status gets you the enhanced SR&ED rate (35% refundable vs. 15% non-refundable), so the Canadian entity should ideally be Canadian-controlled if you're stacking SR&ED.

What "no double-dipping" actually means

You can't reimburse the same expense from both programs. The R&D work funded by IRAP must be performed in Canada by the Canadian entity. The R&D work funded by SBIR must be performed in the US by the US entity.

But the projects can be related. Your Canadian team could develop one module or component via IRAP while your US team develops another via SBIR. As long as the work scopes, budgets, and teams are distinct, you're fine.

Why applying to both is more than just more money

The strategic benefits of applying to both programs:

• SBIR validation signals credibility to US investors and government buyers. A 2017 study in the American Economic Review (Howell, "Financing Innovation") found that an early SBIR award roughly doubles the probability of subsequent VC investment.
• IRAP plus SR&ED keeps your Canadian R&D burn rate manageable (60%+ cost offset)
• Phase III sole-source contracts open US government procurement doors without competitive bidding
• Funded R&D in both countries makes you a more attractive partner for government contracts requiring domestic performance

When to choose which

Choose IRAP if:

• You're a Canadian-incorporated SME (or can establish one)
• Your R&D team is based in Canada
• You want a collaborative, guided application process
• You need moderate funding faster ($75K-$200K in 3-6 months)
• You want to stack with SR&ED for maximum R&D cost offset
• This is your first grant application (the ITA hand-holding matters)

Choose SBIR if:

• You're a US-based small business (or have a qualifying US subsidiary)
• You need larger awards ($150K-$315K Phase I depending on agency, up to $2.1M Phase II)
• Your technology aligns with a specific US agency's mission
• You want the VC validation signal that comes with a competitive federal award
• You're targeting US government customers (Phase III is the path to procurement)

Apply to both if:

• You have (or plan to establish) entities in both countries
• Your R&D has distinct US and Canadian components
• You can maintain separate books and compliance for each jurisdiction
• You're building for government customers on both sides of the border
• You want to maximize non-dilutive funding while keeping burn rates low in both markets

What's changing in 2026

IRAP: The NRC is absorbing Sustainable Development Technology Canada (SDTC) programming, adding a new clean technology funding stream. New sub-programs include AI Assist ($100M over 5 years) and Defence Industry Assist ($244.2M). The planned transition to the Canada Innovation Corporation has been delayed to 2026-2027.

SBIR: Reauthorization through 2031 passed Congress in March 2026 (awaiting presidential signature). New Strategic Breakthrough Awards of up to $30M for Phase II alumni scaling critical technologies. Enhanced foreign-affiliation screening for all awardees. New proposal submission limits to prevent mass-submission shops from flooding agencies. Check sbir.gov for current status.

The bottom line

IRAP and SBIR aren't competitors. They're complementary programs in different jurisdictions with different strengths. IRAP is easier to access and comes with built-in advisory support. SBIR offers larger awards, stronger validation signals, and a path to US government procurement.

If you only operate in one country, the choice is made for you. If you're cross-border (or thinking about it), the combination of both programs, plus SR&ED in Canada and R&D tax credits in the US, creates one of the strongest non-dilutive funding stacks available to a tech startup anywhere in North America.

We've written IRAP applications alongside NSF SBIR proposals for the same client in the same quarter. Most US grant firms have never read an NRC contribution agreement, and most Canadian firms don't touch SBIR.
