IRAP + SR&ED Stacking: How to Claim Both in the Same Fiscal Year (2026 Guide)

The Short Answer: Yes, You Can Claim Both IRAP and SR&ED in the Same Year

You can claim IRAP and SR&ED in the same fiscal year. They are separate programs administered by separate federal agencies, and Canada's tax and grant rules explicitly permit stacking them. The single rule you must follow is this: you cannot claim the same expenditure under both programs. Costs that IRAP funds are excluded from your SR&ED eligible expenditure pool, and the costs IRAP does not fund remain fully available for SR&ED. GrantOps tracks this cost segregation automatically, so you capture every eligible dollar from both programs without risking double-counting.

For Canadian founders and CFOs trying to maximize R&D funding: a company with $1.2 million in annual R&D spend and a $400K IRAP grant can realistically recover $640,000 or more in combined IRAP grants plus SR&ED tax credits in a single fiscal year, representing a 53% effective recovery rate on total R&D costs. This guide explains exactly how to get there.

Can You Claim IRAP and SR&ED in the Same Year?

Yes. This is one of the most frequently misunderstood points in Canadian R&D funding. Many founders assume that receiving a government grant for R&D automatically reduces or eliminates their SR&ED eligibility. That assumption leaves real money on the table.

IRAP and SR&ED are independent programs with no eligibility conflict:

• IRAP is administered by the National Research Council of Canada (NRC). It is a non-repayable grant contribution that funds a defined percentage of eligible project costs during the R&D period. Your Industrial Technology Advisor (ITA) approves milestones and releases payments.
• SR&ED is administered by the Canada Revenue Agency (CRA). It is a tax credit (refundable for qualifying CCPCs) claimed annually on your corporate tax return via the T661 form. It applies to R&D expenditures incurred during your fiscal year.

The two programs operate on entirely different timelines, have different eligible cost definitions, and are reviewed by different government bodies. There is nothing in either program's rules that prevents a company from participating in both simultaneously.

The only coordination required is cost segregation: tracking which costs IRAP funded and ensuring those same costs are not included in your SR&ED claim. Once that segregation is in place, the programs complement each other powerfully. See our IRAP vs SR&ED comparison guide for a full side-by-side breakdown of how the two programs differ.

How Stacking Works: The Cost Segregation Rule Explained

The cost segregation rule is the legal and administrative foundation of all IRAP-SR&ED stacking. Understanding it precisely is what separates companies that maximize their combined recovery from those that trigger CRA adjustments.

The rule, stated plainly: Any cost that is funded, in whole or in part, by an IRAP contribution must be excluded from your SR&ED eligible expenditures to the extent of that IRAP funding.

This comes from the Income Tax Act's rules on government assistance. IRAP contributions are classified as government assistance. CRA requires that government assistance received for an expenditure reduce the SR&ED expenditure pool by the amount of that assistance. The result is that the IRAP-funded portion of any cost is no longer SR&ED eligible, but the self-funded portion remains fully eligible.

A simple illustration:

Suppose you employ a software engineer whose salary is $120,000 per year. That engineer spends 100% of their time on an IRAP-approved project. IRAP covers 50% of their salary ($60,000). You cover the remaining 50% ($60,000).

• IRAP-funded portion: $60,000. This is excluded from SR&ED.
• Self-funded portion: $60,000. This remains fully SR&ED eligible.

If the engineer spends only 70% of their time on SR&ED-eligible activities (with the other 30% on commercial work, management, or non-eligible tasks), the SR&ED calculation applies to the self-funded eligible portion only. The math gets layered, which is why automated tracking matters.

Key implications of the cost segregation rule:

1. Partial IRAP coverage does not eliminate SR&ED eligibility. It reduces the SR&ED base proportionally.
2. Costs that IRAP explicitly does not fund (overhead categories that fall outside IRAP's scope, for example) remain 100% SR&ED eligible.
3. The segregation must be applied at the individual cost level, not just as a top-line reduction. You cannot simply subtract your total IRAP grant from your total R&D spend and call the remainder your SR&ED pool. CRA expects cost-level tracking.

A Worked Example: The Stacking Math

The clearest way to understand stacking is to walk through a complete example.

Company profile: Maple Stack Inc., a SaaS startup based in Toronto. Fiscal year end: December 31. Annual R&D spend: $1.2 million. Active IRAP project: AI-driven compliance automation tool. IRAP contribution agreement: covers 80% of eligible project costs up to $400,000.

Total R&D costs for the fiscal year:

IRAP recovery: $400,000 (received during the fiscal year as milestone payments).

SR&ED eligible expenditure pool:

For SR&ED purposes, the eligible base includes the self-funded portion of costs that meet CRA's SR&ED eligibility criteria. Not all self-funded costs are necessarily SR&ED eligible (overhead is partially eligible via the proxy method, non-R&D activities are excluded), but for this example, assume $750,000 of the $800,000 self-funded costs meet the eligibility criteria.

SR&ED tax credit (CCPC, 35% refundable rate on first $6M):

$894,500 x 35% = $313,075

Total government funding recovery:

Without IRAP, the SR&ED pool would have been larger ($1.15M eligible vs $894.5K), yielding approximately $402,500 in SR&ED credits but zero IRAP funding. The stacked approach delivers $310,575 more in total government funding.

Timeline Coordination: How IRAP and SR&ED Fit Together in Your Fiscal Year

One reason stacking feels complicated is that the two programs operate on completely different timelines. Understanding the sequencing prevents errors in both your IRAP reporting and your SR&ED claim.

IRAP timeline (during the project):

• Contribution agreement is signed before or early in the project.
• Costs are incurred and tracked against IRAP-approved budget categories.
• Milestone payments are requested as deliverables are completed, typically quarterly.
• Your ITA reviews progress reports before each payment.
• The project closes when all milestones are complete or the agreement term ends.

SR&ED timeline (after the fiscal year):

• Your fiscal year ends (December 31 for most companies, or your chosen year-end).
• SR&ED-eligible activities and expenditures incurred during the year are compiled.
• The T661 form and supporting schedules are prepared and filed with your T2 corporate return.
• The filing deadline is 18 months after your fiscal year-end.
• CRA processes the claim and issues a refund, typically 6-12 months after filing (faster for online filings).

The critical sequencing insight: IRAP funds costs as they occur. SR&ED claims them retrospectively. This means your IRAP milestone payments arrive during the year while your SR&ED refund arrives 6-18 months after the year ends. For cash flow planning, IRAP is your near-term funding bridge. SR&ED is your annual retrospective recovery.

For fiscal year coordination, the rule is straightforward: segregate costs by the fiscal year in which they were incurred. If your IRAP project runs from March of Year 1 to September of Year 2, your Year 1 SR&ED claim excludes only the IRAP-funded costs incurred in Year 1. Your Year 2 SR&ED claim excludes only the IRAP-funded costs incurred in Year 2. Do not average or spread the exclusion across years.

What Costs Qualify for Each Program

The cost definitions for IRAP and SR&ED overlap significantly but are not identical. Understanding where they differ helps you assign costs correctly.

The practical takeaway: IRAP is primarily a salary subsidy for defined project personnel. SR&ED covers a broader range of costs including materials, overhead, and contractors, applied across all SR&ED activities, not just those within an IRAP project scope.

This difference creates an important opportunity. Many companies have significant SR&ED-eligible costs (materials, software licenses, overhead) that IRAP does not touch at all. Those costs face no IRAP exclusion and flow directly into the SR&ED pool at full value.

Common Stacking Mistakes That Trigger CRA Issues

Most errors in IRAP-SR&ED stacking fall into a small number of categories. Knowing them in advance is far cheaper than discovering them during a CRA review.

Mistake 1: Reducing SR&ED by the gross IRAP amount instead of cost-by-cost

Companies sometimes subtract their total IRAP grant from their total R&D spend and treat the remainder as their SR&ED pool. This is incorrect. The exclusion must be applied at the cost level. If IRAP funds 80% of specific salaries, you exclude 80% of those specific salaries. Other costs that IRAP did not touch remain in the pool at full value.

Mistake 2: Including IRAP-funded costs in the SR&ED base because the IRAP project "overlaps" with SR&ED-eligible work

Some companies reason that because their IRAP project also qualifies under SR&ED criteria, they can claim the same activities under both. The activity eligibility is irrelevant. What matters is whether the same costs are funded by both programs. If IRAP pays for it, CRA excludes it from SR&ED, regardless of how eligible the underlying work would otherwise be.

Mistake 3: Forgetting that IRAP reduces the SR&ED base in the year the IRAP payment is received, not the year the costs were incurred

Under the Income Tax Act, government assistance is recognized when it becomes receivable. If IRAP approves a milestone in December but you receive the payment in January of the next fiscal year, the exclusion applies to the year the assistance became receivable, which is typically the year of approval, not necessarily the year of payment. This requires careful review with your tax advisor.

Mistake 4: Multi-year IRAP projects spread across the wrong fiscal year

As noted above, if your IRAP project spans two fiscal years, apply the exclusion in the year each cost was incurred, not lumped into one year or averaged across both.

Mistake 5: Failing to document cost segregation at a level CRA can audit

CRA requires that you be able to demonstrate, if asked, how you determined which costs were IRAP-funded and which were SR&ED eligible. A spreadsheet showing salary allocations, contractor invoices mapped to projects, and a reconciliation of your IRAP claims against your SR&ED pool is the minimum documentation standard.

How GrantOps Automates Dual-Program Tracking

The core challenge in IRAP-SR&ED stacking is operational, not conceptual. Once you understand the rules, the question is how to track costs at sufficient granularity across a full fiscal year without burdening your engineering and finance teams.

GrantOps connects directly to the systems where R&D activity actually happens: GitHub for code and commits, Jira for project and sprint tracking, and Slack for team activity signals. It maps those signals to eligible R&D time at the individual contributor level.

For dual-program tracking specifically, GrantOps maintains a separate cost attribution layer that distinguishes IRAP-funded activities from SR&ED-only activities:

IRAP project tagging: When you configure an IRAP project in GrantOps, you define the project scope, the contribution agreement dates, and the IRAP-funded cost categories. GrantOps flags all activities that fall within that scope and tracks the IRAP-funded portion versus your self-funded portion based on your contribution agreement percentage.

SR&ED pool calculation: GrantOps automatically excludes IRAP-funded costs from the SR&ED eligible expenditure pool. You see in real time how much of each cost category is SR&ED eligible, how much is IRAP-allocated, and how much is neither (non-R&D activities). There is no manual spreadsheet reconciliation.

T661 and IRAP progress report generation: Both programs require documentation in specific formats. The T661 technical narratives, financial schedules, and supporting documentation for CRA are generated from the same underlying activity data that produces your IRAP milestone reports for your ITA. GrantOps writes the output formats differently, but the source data is shared, which means you are not describing the same work twice in two different documents from scratch.

Audit trail: Every cost allocation in GrantOps is traceable to a source record: a commit, a ticket, a timesheet entry, or a contractor invoice. If CRA questions how you calculated your SR&ED base net of IRAP assistance, the audit trail is ready.

Step-by-Step: The Optimal Order of Operations for Stacking Both Claims

For companies new to dual-program claiming, here is the recommended sequence for a fiscal year where you are running both IRAP and SR&ED simultaneously.

Before the fiscal year begins (or as early in the year as possible):

1. Contact NRC-IRAP through your regional office and request an ITA assignment. The IRAP application process takes 4-6 months from first contact to contribution agreement, so starting early in the fiscal year gives you maximum funding coverage.
2. Set up your cost tracking system (or configure GrantOps) to separate IRAP-eligible project costs from all other R&D costs from day one. Retroactive reconstruction of cost allocations is possible but time-consuming.
3. Identify all SR&ED-eligible activities your company conducts, including activities that fall entirely outside the IRAP project scope. These are your "pure SR&ED" activities and they face no IRAP exclusion.

During the fiscal year:

1. Submit IRAP milestone claims to your ITA on the schedule specified in your contribution agreement. Keep copies of all approved milestone reports.
2. Track engineering time, contractor costs, and materials at the project level continuously. Do not rely on year-end reconstruction.
3. As IRAP milestone payments are received, record the exact costs they offset. This becomes the basis for the CRA exclusion calculation.

After the fiscal year ends:

1. Compile your SR&ED eligible expenditures by cost category.
2. Apply the IRAP exclusion: remove IRAP-funded costs from the eligible pool at the cost level.
3. Prepare and file your T661 with your T2 corporate tax return, citing the net eligible expenditures after IRAP exclusion.
4. File within 18 months of your fiscal year-end. Earlier filing means earlier refund.

Ongoing:

1. If your IRAP project continues into the next fiscal year, repeat the segregation for that year's costs separately.
2. Review your combined IRAP-SR&ED recovery annually and adjust your project structure if needed to optimize the split.

Your Total Recovery Potential

The numbers make the case for stacking clearly. A Canadian CCPC with $1.2 million in annual R&D spend can realistically achieve:

• IRAP grant: $300,000-$500,000 depending on project scope and NRC approval.
• SR&ED refund (on remaining eligible costs): $200,000-$350,000 at the 35% rate.
• Combined recovery: $500,000-$850,000 per year, or 40-70% of total R&D costs.

The same company relying on SR&ED alone would recover approximately $420,000 (35% of $1.2M eligible costs), assuming full eligibility. Stacking with IRAP adds a further $100,000-$430,000 in government funding, even after accounting for the reduced SR&ED base.

That differential is the value of understanding and executing the stacking rules correctly.
