IRAP vs SR&ED: Which R&D Funding Program Should You Apply For?

IRAP and SR&ED: Canada's Two Biggest R&D Funding Programs

If your company does research and development in Canada, two programs dominate the funding landscape: NRC-IRAP and SR&ED. Together, they deliver billions of dollars annually to Canadian businesses. Yet most founders and R&D leaders struggle to understand the differences between them, which one to apply for first, and whether they can use both at the same time.

This guide answers all of those questions. By the end, you will know exactly which program fits your situation, how to maximize your total funding, and how to avoid the mistakes that leave money on the table.

The short answer: most companies doing genuine R&D should apply for both. IRAP is a non-repayable grant you receive before or during your project. SR&ED is a refundable tax credit you claim after your fiscal year ends. They serve different purposes, operate on different timelines, and, critically, they can be stacked together.

But the details matter. Let us walk through them.

How IRAP Works: The Key Details

IRAP is Canada's flagship non-repayable R&D grant program. The National Research Council has run it since 1962, and it distributed over $550 million to Canadian SMEs in the 2025-2026 fiscal year.

The IRAP Process

1. Initial contact: You reach out to NRC-IRAP (or are referred by a platform like GrantOps) and are assigned an Industrial Technology Advisor (ITA).
2. Business assessment: Your ITA evaluates your company, team, project, and financial capacity over a series of meetings.
3. Proposal development: You and your ITA co-develop a formal project proposal with milestones, budgets, and technical objectives.
4. Internal review: NRC reviews and approves the proposal.
5. Contribution agreement: You sign a funding agreement. Only costs incurred after this date are eligible.
6. Execution and claims: You submit quarterly milestone claims with timesheets, invoices, and progress reports. Payments arrive within 30-45 days of each approved claim.
7. Final report: You submit a closing report and receive your final payment.

What Makes IRAP Unique

• Free money with no strings: You never repay it and you give up no equity.
• Built-in mentorship: Your ITA is a senior technical professional who provides strategic guidance beyond just the funding.
• Must apply before work begins: This is the single biggest difference from SR&ED. You cannot get IRAP funding for work you have already completed.
• Relationship-driven: IRAP is not a faceless online portal. Your ITA is a real person who advocates for your project internally.

How SR&ED Works: The Key Details

SR&ED (pronounced "shred") is the largest single source of federal support for business R&D in Canada, delivering approximately $4.5 billion annually in tax incentives. It is administered by the Canada Revenue Agency as part of the Income Tax Act.

The SR&ED Process

1. Conduct R&D during your fiscal year: There is no pre-approval. You do the work first.
2. Identify eligible projects: At or after year-end, you determine which projects involved technological uncertainty, systematic investigation, and technological advancement.
3. Prepare the T661 form: This includes detailed technical narratives for each project and financial schedules calculating your eligible expenditures.
4. File with your corporate tax return: The T661 is filed alongside your T2 corporate income tax return, within 18 months of your fiscal year-end.
5. CRA processing: CRA reviews the claim. If accepted without review, refunds typically arrive within 60-120 days.
6. Potential CRA review: If selected for review, a CRA Research and Technology Advisor (RTA) may request additional documentation or conduct a site visit. This can add 6-12 months.

What Makes SR&ED Unique

• Retroactive: You claim SR&ED after the fact. No pre-approval needed. This means you can claim for R&D you have already done.
• No cap on company size: Unlike IRAP, companies of any size can claim SR&ED.
• Annual, not project-based: One claim covers all your eligible R&D for the entire fiscal year.
• Cash refund for CCPCs and ECPCs: Canadian-controlled private corporations and eligible Canadian public corporations get a 35% fully refundable credit on the first $6M of qualifying expenditures. This puts cash directly in your bank account.
• Higher audit risk: CRA reviews a significant portion of SR&ED claims, especially first-time filers and claims above certain thresholds.

Decision Flowchart: Which Program Should You Choose?

Use this decision framework to determine the right starting point for your company.

Choose IRAP If...

• You have a defined R&D project that has not yet started (or is in very early stages)
• You are a small or medium-sized company (500 or fewer employees)
• You need cash flow now, not 12-18 months from now
• You want mentorship and guidance from a senior technical advisor, not just funding
• Your R&D involves clear technological uncertainty with a defined scope and timeline
• You have the bandwidth to manage milestone reporting (quarterly claims, progress reports)
• You are pre-revenue or early-revenue and need non-dilutive capital to fund development

Choose SR&ED If...

• You have already completed R&D work and want to recoup a portion of those costs retroactively
• Your company has more than 500 employees (IRAP size limit does not apply to SR&ED)
• You prefer a hands-off process, file once a year, no ongoing milestone reporting
• You have multiple concurrent R&D projects and want to bundle them into a single annual claim
• You are doing ongoing, continuous R&D that does not fit neatly into a project-based structure
• You want to claim costs like overhead and rent (eligible under SR&ED proxy method but not under IRAP)

Apply for Both If...

• You are a CCPC with 500 or fewer employees doing R&D in Canada, this describes the vast majority of tech startups and scale-ups
• You have a new R&D project launching (apply to IRAP) and you have ongoing R&D from the current or prior fiscal year (claim SR&ED)
• You want to maximize your total funding rate, stacking IRAP and SR&ED can push your effective government funding above 70% of total R&D costs
• You are willing to invest the time to manage both programs (or use a platform like GrantOps that handles both simultaneously)

Bottom line: If you are an SME doing R&D in Canada, the question is almost never "IRAP or SR&ED?" It is "How do I optimize both?"

Stacking IRAP and SR&ED: How It Works

Yes, you can absolutely use both IRAP and SR&ED for the same R&D activities. The key rule is simple: you cannot claim the same dollar under both programs. The costs funded by IRAP are excluded from your SR&ED claim. But your self-funded portion remains fully SR&ED-eligible.

Stacking Example: SaaS Startup Doing Machine Learning Research

Imagine a SaaS startup with 30 employees building a machine learning platform for supply chain optimization. Their annual R&D spend is $1.2 million, primarily in developer and data scientist salaries.

Step 1: IRAP Application

The company applies for IRAP with a defined 18-month project to develop a novel demand forecasting algorithm. NRC approves a $500,000 contribution covering approximately 60% of the project's eligible costs.

Step 2: IRAP Execution

Over 18 months, the company submits quarterly milestone claims and receives $500,000 in non-repayable contributions. This cash arrives during the project, directly improving cash flow.

Step 3: SR&ED Claim (Year 1)

At the end of fiscal year 1, the company files an SR&ED claim. Their total eligible R&D expenditures for the year were $800,000 in salaries and overhead. The $350,000 covered by IRAP during that fiscal year is excluded. The remaining $450,000 is claimed under SR&ED at the 35% enhanced rate.

SR&ED refund for Year 1: $157,500

Step 4: SR&ED Claim (Year 2)

The IRAP project continues into year 2, with $150,000 of IRAP contributions received. The company's total R&D spend is $900,000. After excluding the IRAP-funded portion, $750,000 is SR&ED-eligible.

SR&ED refund for Year 2: $262,500

Total Government Funding Over 2 Years:

That is $920,000 in non-dilutive, non-repayable government funding on $1.7 million of R&D investment. No equity given up. No loan to repay. And because IRAP payments arrive during the project while SR&ED refunds come after year-end, the company has predictable cash flow throughout.

Why Most Companies Leave Money on the Table

Despite the clear benefits of stacking, many companies only use one program. Common reasons include:

• Lack of awareness: They know about SR&ED but have never heard of IRAP, or vice versa
• Consultant tunnel vision: Their SR&ED consultant only handles SR&ED and does not mention IRAP
• Timing mismatch: They discover IRAP after their project has already started (IRAP requires pre-approval)
• Complexity: Managing two programs with different processes, timelines, and reporting requirements feels overwhelming

This is exactly the problem GrantOps was built to solve. The platform automatically identifies both IRAP and SR&ED eligibility, calculates optimal stacking strategies, and manages the documentation for both programs in parallel. Check your eligibility for both programs in 60 seconds.

Common Mistakes When Choosing Between IRAP and SR&ED

Mistake 1: Waiting to Apply for IRAP Until Your Project Is Complete

IRAP requires pre-approval. If your R&D is already done, IRAP cannot help you. However, SR&ED can be claimed retroactively. If you missed the IRAP window, file an SR&ED claim for the completed work and apply to IRAP for your next project.

Mistake 2: Assuming SR&ED Is Automatic

SR&ED is a tax credit, but it is not automatic. You must file a T661 form with detailed technical narratives demonstrating that your work meets CRA's five eligibility criteria. Poorly prepared claims are frequently reduced or denied on review.

Mistake 3: Double-Dipping on the Same Costs

You cannot claim the same expenditure under both IRAP and SR&ED. If IRAP covers $300,000 of a $500,000 project, only the remaining $200,000 is SR&ED-eligible. Claiming the full $500,000 under SR&ED is a red flag that can trigger a CRA review and penalties.

Mistake 4: Not Tracking Time Properly

Both IRAP and SR&ED require evidence of how R&D staff spend their time. IRAP requires timesheets with milestone claims. SR&ED requires contemporaneous documentation linking employee time to specific eligible projects. Companies that do not track time from the start scramble to reconstruct records later, and often leave money behind.

Mistake 5: Using a Consultant for SR&ED But Not Exploring IRAP

Many SR&ED consultants charge 15-25% contingency fees and focus exclusively on SR&ED. They have no incentive to tell you about IRAP. Always independently evaluate your IRAP eligibility, or use a platform like GrantOps that covers both programs.

Frequently Asked Questions: IRAP vs SR&ED

Can I apply for IRAP and SR&ED at the same time?

Yes. They are completely independent programs administered by different federal agencies (NRC for IRAP, CRA for SR&ED). You can apply for IRAP at any time and file SR&ED claims annually with your corporate tax return. The only coordination required is ensuring you do not claim the same costs under both programs.

Which program gives more money?

It depends on your situation. For a single defined project, IRAP can provide up to $10 million in direct funding. SR&ED has no per-project cap but the enhanced 35% refundable rate is limited to the first $6 million in qualifying expenditures annually (approximately $2.1 million maximum refund at that rate). For companies with large ongoing R&D budgets, SR&ED often delivers more total dollars over time. For companies with a specific high-cost project, IRAP may provide a larger single contribution.

Is IRAP harder to get than SR&ED?

IRAP is more competitive in the sense that it is a discretionary grant, NRC decides whether to fund your project based on merit, team capability, and economic benefit to Canada. SR&ED is an entitlement, if your work meets the eligibility criteria, you are legally entitled to the tax credit. However, SR&ED claims require significant documentation and are subject to CRA review, which can feel like its own form of gatekeeping.

How long does each program take?

IRAP: approximately 4-6 months from first contact to first milestone payment. SR&ED: approximately 6-18 months from filing your claim to receiving your refund. If your SR&ED claim is selected for CRA review, add another 6-12 months. IRAP delivers cash faster during the project; SR&ED delivers a lump sum after the fact.

Do I need a consultant for either program?

For IRAP, you do not typically use a consultant. Your assigned ITA fills the advisory role. For SR&ED, many companies use consultants to prepare the T661 form and technical narratives, especially first-time filers. However, consultants typically charge 15-25% of your refund, which significantly reduces your net benefit. GrantOps automates SR&ED claim preparation at a fraction of traditional consultant costs.

What if my company has more than 500 employees?

You are not eligible for IRAP, but you can still claim SR&ED. The SR&ED program has no company size restriction. The enhanced 35% refundable rate is available to Canadian-controlled private corporations (CCPCs) and eligible Canadian public corporations (ECPCs); companies that are neither receive the standard 15% non-refundable credit. The enhanced rate phases out based on prior-year taxable capital, beginning at $15 million and reaching zero at $75 million.

Can startups with no revenue apply?

Yes, to both. IRAP actively funds pre-revenue companies, in fact, early-stage companies are a core part of the IRAP mandate. SR&ED is also available to pre-revenue companies, and as a refundable credit for qualifying CCPCs, you receive a cash refund even if you owe no taxes. Pre-revenue startups should prioritize IRAP first (for immediate cash flow) and file SR&ED claims annually for their self-funded R&D costs.

The Bottom Line: Do Not Choose, Stack

The single most important takeaway from this guide is that IRAP vs SR&ED is usually a false choice. The two programs are designed to work together, and the Canadian government expects companies to use both.

Your action plan:

1. Assess IRAP eligibility for your next R&D project, if you have not started the work yet, apply now
2. File SR&ED claims for all R&D work completed in your most recent fiscal year, you may have 18 months from year-end to file
3. Track time and costs meticulously from day one, both programs require it, and good records maximize your claims
4. Calculate your stacking potential, the combination of IRAP contributions and SR&ED refunds on your remaining costs often exceeds 60% of total R&D spend
