SR&ED Tax Credits in BC: What Counts as R&D and How to Claim (2026)

The Scientific Research and Experimental Development (SR&ED) program is the single largest source of government R&D funding in Canada. In the 2023-2024 fiscal year alone, the federal government provided over $3.6 billion in SR&ED tax incentives to more than 20,000 claimants nationwide. Add BC's provincial credit on top of that, and a qualifying business in British Columbia can recover up to 45 cents on every dollar spent on eligible research and development.

Yet most BC businesses leave money on the table. Some do not know the program exists. Others assume it is only for pharmaceutical labs or university spin-offs. Many have eligible work happening right now — in their software teams, on their manufacturing floors, in their food production facilities — and have never filed a claim.

This guide explains exactly what SR&ED is, what the current federal and BC provincial credit rates are (including the significant changes from Budget 2026), which activities qualify across different industries, and how to file a successful claim. If your business solves technical problems as part of what it does, there is a good chance you are leaving tens of thousands of dollars — or more — unclaimed every year.

What Is SR&ED?

SR&ED (Scientific Research and Experimental Development) is a federal tax incentive program administered by the Canada Revenue Agency (CRA) that provides tax credits and, in many cases, cash refunds to Canadian businesses that conduct research and development in Canada. It is designed to encourage innovation by reducing the after-tax cost of R&D. BC adds its own provincial credit on top, making the combined benefit one of the most generous in the country.

The program is not a grant — you do not apply in advance and wait for approval. Instead, you claim the credit when you file your corporate tax return, retroactively recovering a percentage of the money you already spent on qualifying R&D activities.

SR&ED Tax Credit Rates in BC

Understanding the rate structure is critical because the benefit you receive depends on your company type, size, and where you perform the work. Here are the current rates as of 2026:

What does this mean in practice? If your BC-based CCPC spends $200,000 on eligible SR&ED activities, you can receive a cash refund of up to $90,000 — even if your company owes no taxes. That is real cash deposited into your business bank account by the CRA and the BC government. Understanding the SR&ED tax credit in British Columbia starts with knowing these rates.

For larger companies or non-CCPCs, the 15% federal credit is non-refundable (it can only reduce taxes owed), but the 10% BC provincial credit remains fully refundable. This means even large corporations performing R&D in BC get at least 10% back as cash.

Budget 2026 Changes

Budget 2026 introduced the most significant improvements to the SR&ED program in over a decade. If you reviewed SR&ED in the past and decided it was not worth pursuing, it is time to look again. Here are the key changes:

BC Provincial SR&ED Credit Is Now Permanent

Previously, BC's 10% refundable SR&ED tax credit was a temporary measure that required renewal in every provincial budget. This created uncertainty for businesses planning multi-year R&D projects. As of Budget 2026, the BC provincial credit has been made permanent, giving businesses the confidence to invest in long-term research knowing the credit will be there when they file.

Federal Expenditure Limit Doubled

The most impactful change for small and mid-sized companies: the federal SR&ED expenditure limit has been doubled from $3 million to $6 million. This is the threshold below which CCPCs receive the enhanced 35% refundable rate instead of the standard 15% non-refundable rate.

Previously, a CCPC spending $5 million on eligible R&D would receive the 35% rate on only the first $3 million and the 15% rate on the remaining $2 million. Now, the full $5 million qualifies for the 35% rate. For that company, the change means an additional $400,000 in refundable credits.

Phase-Out Threshold Increased

The expenditure limit phases out as a company's taxable income and taxable capital increase. Budget 2026 raised the income threshold at which the phase-out begins, meaning more mid-sized companies now qualify for the full enhanced rate. Companies that were previously caught in the phase-out zone — too large for the full enhanced rate but not large enough to absorb a non-refundable credit — are the biggest winners from this change.

What This Means for BC Businesses

The combined effect is straightforward: more companies now qualify for the maximum 45% combined rate on a larger pool of eligible spending. If your BC-based CCPC has R&D expenditures between $3 million and $6 million, Budget 2026 could mean hundreds of thousands of dollars in additional refundable credits compared to what you would have received under the old rules.

Even if your R&D spending is under $3 million (and it qualifies under the old rules too), the permanence of the BC credit and the raised phase-out thresholds provide greater certainty and potentially higher claims.

What Qualifies as SR&ED?

This is where most businesses get confused — and where most money is left on the table. The CRA uses three criteria to determine whether work qualifies. All three must be present.

Scientific or Technological Uncertainty

Your work must involve attempting to resolve a scientific or technological uncertainty — something that could not be resolved by standard practice or publicly available knowledge at the time you started the work.

The key question: Did you know it would work before you tried it? If the answer is no — if the outcome was uncertain even to someone with relevant expertise — this criterion is likely met.

Examples of technological uncertainty:

• You are building a software system and cannot determine whether your architecture will handle the required throughput
• You are developing a manufacturing process and cannot predict whether the material will behave as expected at production scale
• You are formulating a food product and cannot determine whether the new preservation method will maintain flavour and texture over the required shelf life

What is NOT uncertainty: choosing between known solutions, applying established techniques to a routine problem, or implementing off-the-shelf technology according to its documentation.

Systematic Investigation

The work must follow a systematic investigation or search — meaning you approached the problem methodically. You formed hypotheses, designed experiments or prototypes, tested them, and analyzed the results.

This does not mean you need a formal lab or peer-reviewed papers. It means you followed a logical process rather than random guessing. Most professional engineering and development work is inherently systematic.

What counts: design documents, architecture decisions, test plans, prototyping iterations, performance benchmarks, and documented analysis of results.

What does NOT count: pure trial-and-error without analysis, gut-feeling decisions without technical rationale.

Technological Advancement

The work must aim to achieve a technological advancement — new knowledge or capability that did not previously exist, at least within your company's knowledge base.

Important: the advancement does not need to be a breakthrough. It does not need to be novel to the entire world. It needs to be an advance beyond your starting point. If you learned something about how a technology behaves, developed a new method, or pushed the boundaries of what was previously possible in your context, this criterion is met.

Even failed projects can qualify. If you attempted to resolve a technological uncertainty through systematic investigation, the fact that your approach did not work is still an advancement — you now know something you did not know before.

SR&ED by Industry — Does YOUR Work Qualify?

One of the biggest misconceptions about SR&ED is that it is only for biotech labs and pure research. In reality, businesses across many industries perform qualifying work every day without realizing it. Here is what qualifies in the sectors we work with most often at GrantEdge.

Software and SaaS

Qualification likelihood: HIGH

Software development is one of the most common sources of SR&ED claims in Canada, and BC's tech sector is a major beneficiary. Qualifying activities include:

• Developing new algorithms or computational methods that go beyond known approaches
• Building AI and machine learning models where the training methodology, architecture, or data pipeline involves resolving technological uncertainty
• Performance optimization where you are pushing system performance beyond what established approaches can achieve (not just tuning configuration)
• Developing new frameworks or tools that require resolving architectural uncertainties
• Integration challenges where connecting systems involves overcoming technical limitations that have no documented solution

What does NOT qualify: routine software development using established methods, UI/UX design work, configuring commercial off-the-shelf software, data entry or content management.

Example: A Vancouver SaaS company developing a real-time data processing pipeline that needed to handle 10x the throughput of any existing solution they could find. They experimented with multiple architectural approaches, benchmarked each, and developed a custom streaming protocol. The uncertainty (whether they could achieve the required throughput with acceptable latency), the systematic testing, and the resulting advancement all qualify.

Manufacturing

Qualification likelihood: HIGH

Manufacturing companies often have extensive SR&ED-eligible work embedded in their operations:

• Developing new manufacturing processes or significantly improving existing ones
• Working with new materials where behaviour at production scale is uncertain
• Designing tooling or fixtures that require solving novel engineering challenges
• Improving product quality through process changes that require experimentation
• Scaling from prototype to production where scale-up introduces new technical problems

What does NOT qualify: routine quality control, production using established methods, maintenance and repairs.

Example: A BC manufacturer developing a new welding technique for a lightweight alloy where existing methods caused material degradation. They tested multiple approaches, analyzed metallurgical results, and developed a proprietary process. Every hour of engineering and shop-floor experimentation was SR&ED-eligible.

Construction

Qualification likelihood: MODERATE (case-dependent)

Construction is trickier because much of the work follows established building codes and methods. However, SR&ED claims are possible when:

• Developing new structural methods that go beyond standard engineering practice
• Creating innovative building systems (modular construction, new insulation approaches)
• Adapting to extreme conditions where standard methods are insufficient (seismic, permafrost, extreme weather)
• Developing new construction materials or novel applications of existing materials

What does NOT qualify: building to code using established methods, standard engineering calculations, applying known techniques to new projects.

Example: A BC construction firm developing a modular building system for northern communities where conventional construction was impractical. They had to resolve uncertainties around thermal performance, structural integrity during transport, and assembly methods in extreme cold. The engineering and prototyping work qualified.

Food and Beverage

Qualification likelihood: HIGH

Food science involves significant SR&ED-eligible work, particularly around:

• Scaling recipes from kitchen to production where behaviour changes unpredictably at scale
• Developing new preservation methods to extend shelf life without compromising quality
• Creating new textures, formulations, or flavour profiles that require systematic experimentation
• Adapting products for new dietary requirements (allergen-free, plant-based) where substitution is not straightforward
• Improving production efficiency through process innovations that require resolving technical uncertainty

What does NOT qualify: following existing recipes, routine quality testing, market research on flavour preferences.

Example: A BC craft brewery developing a new fermentation process for a non-alcoholic beer that maintained the flavour profile of their flagship product. Standard de-alcoholization methods degraded the taste. They systematically tested multiple fermentation approaches, yeast strains, and temperature profiles over six months. The entire project was SR&ED-eligible.

Clean Tech and Energy

Qualification likelihood: HIGH

Clean technology is one of the strongest sectors for SR&ED claims:

• Developing new energy systems (solar, wind, geothermal, hydrogen) or improving efficiency of existing ones
• Creating environmental remediation processes where the science is uncertain
• Developing carbon capture or reduction technologies
• Building energy storage solutions that push beyond current performance limits
• Creating smart grid or energy management systems with novel technical approaches

Example: A BC clean tech startup developing a waste-to-energy conversion system. The chemical processes at scale were uncertain, and they spent 18 months systematically testing reactor configurations, catalysts, and temperature profiles. The full R&D effort qualified for SR&ED.

Agriculture

Qualification likelihood: HIGH

BC's agricultural sector has significant SR&ED potential:

• Developing new growing methods (vertical farming, hydroponics, aquaponics) where outcomes are technically uncertain
• Crop science — developing new varieties, testing growing conditions, improving yields through experimentation
• Agricultural automation — building or adapting robotic systems for planting, harvesting, or processing
• Developing biological pest control methods or reducing chemical inputs through systematic experimentation
• Precision agriculture — developing sensor systems, data analysis methods, or AI-driven growing optimization

Example: A Fraser Valley greenhouse operation developing an automated climate control system that used sensor data and machine learning to optimize growing conditions. The uncertainty around model accuracy, sensor calibration, and real-time response qualified the development work for SR&ED.

Eligible vs. Ineligible Expenses

Once you have identified qualifying SR&ED activities, you need to determine which costs are eligible. The CRA allows two methods for calculating expenditures: the traditional method and the proxy method. Most small businesses use the proxy method because it is simpler.

Eligible Expenses

• Salaries and wages of employees directly engaged in SR&ED work (including the portion of time spent on eligible activities by employees who also do non-SR&ED work)
• Materials consumed or transformed in the course of SR&ED (raw materials, components, chemicals used in experimentation)
• Subcontractor fees — 80% of amounts paid to arm's-length contractors for SR&ED work performed on your behalf
• Overhead and other expenditures — under the proxy method, you can claim 55% of eligible salary costs as a proxy for overhead (utilities, rent, supplies, etc.) without having to track actual overhead
• Third-party payments — payments to approved research institutes, universities, or other qualifying organizations

Ineligible Expenses

• Capital equipment — machinery, computers, and other capital assets are NOT eligible (this changed in 2014 when capital expenditures were removed from the program)
• Commercial production costs — once your R&D moves into routine production, those costs are not eligible
• Routine quality control and testing — standard QC that does not involve resolving technological uncertainty
• Market research, sales, and marketing — even if related to an R&D project
• Administrative costs — management, HR, accounting (unless directly performing SR&ED work)
• Patent and IP costs — legal fees for patent applications are not SR&ED-eligible

The Proxy Method vs. Traditional Method

Most CCPCs use the proxy method: you calculate eligible salaries, then add 55% of that amount as a proxy for overhead costs, plus materials and contractor fees. This avoids the burden of tracking every overhead item.

The traditional method requires detailed tracking of actual overhead costs but can yield a higher claim if your overhead ratio exceeds 55% of salaries. Companies with expensive lab facilities or significant utility costs may benefit from the traditional method.

How to Claim SR&ED in BC

Filing an SR&ED claim involves both technical and financial components. Here is the step-by-step process:

Step 1: Document Your R&D Throughout the Year

This is the single most important step, and it is where most businesses fail. Do not wait until tax time to document your SR&ED work. The CRA expects contemporaneous documentation — records created at or near the time the work was done.

Keep records of:

• Project objectives and the technological uncertainties you were trying to resolve
• Hypotheses and approaches tested
• Test results, benchmarks, and analysis
• Design documents, architecture decisions, and meeting notes
• Time tracking for employees working on eligible projects

Even informal records — Slack messages, Jira tickets, Git commit histories, lab notebooks — count as contemporaneous documentation.

Step 2: Identify Eligible Projects and Activities

At year-end (or throughout the year with good tracking), identify which projects and which specific activities within those projects meet the three SR&ED criteria: uncertainty, systematic investigation, and advancement.

Not everything in an R&D project qualifies. The initial research and planning, the experimental work, and the analysis qualify. Routine implementation after the uncertainty is resolved does not.

Step 3: Calculate Eligible Expenditures

Determine the eligible costs for each qualifying project:

• Allocate employee time to eligible activities (time tracking is essential)
• Identify materials consumed in experimentation
• Calculate contractor fees (remember, only 80% of arm's-length contractor costs are eligible)
• Apply the proxy method (55% of salaries) or calculate actual overhead

Step 4: Prepare Technical Narratives

For each SR&ED project, you must prepare a technical narrative that describes:

• The scientific or technological uncertainty
• The work done to resolve it (hypotheses, experiments, analysis)
• The advancement achieved (or what was learned, even if the project failed)

These narratives are the heart of your claim. Weak narratives are the primary reason claims are denied or reduced during CRA review. Write them in plain technical language — describe the problem, what you tried, and what you learned.

Step 5: Complete Form T661

CRA Form T661 is the SR&ED claim form. It includes:

• Part 2: Project information and technical narratives
• Part 3: Financial calculations (eligible expenditures)
• Schedule T2SCH31: Investment tax credit calculation

Step 6: File with Your Corporate Tax Return

The T661 and Schedule T2SCH31 are filed with your T2 corporate income tax return. The BC provincial SR&ED credit (claimed on the BC provincial return) is filed automatically as part of the T2 process — there is no separate provincial application.

Critical deadline: The SR&ED claim must be filed within 18 months after the end of your fiscal year. Miss this deadline and you lose the claim entirely. There are no extensions.

Step 7: CRA Review Process

After filing, the CRA may:

• Accept the claim as filed — you receive the refund (typically 60-120 days after filing)
• Request a financial review — they verify your expenditure calculations
• Request a technical review — a CRA research and technology advisor (RTA) reviews your technical narratives and may visit your business to discuss the work

Technical reviews are not audits in the punitive sense. They are conversations about your work. Having good documentation and being able to clearly explain the uncertainties and your process makes these reviews straightforward.

SR&ED Stacking: Combining with Other Programs

SR&ED does not exist in isolation. BC businesses can combine it with other funding programs, though there are rules about how the programs interact. For a comprehensive look at stacking strategies, read our guide on IRAP and SR&ED funding for BC tech startups.

IRAP + SR&ED

The Industrial Research Assistance Program (IRAP) provides non-repayable contributions for R&D projects. When you receive IRAP funding, it reduces your SR&ED expenditure pool — you cannot claim SR&ED credits on costs already reimbursed by IRAP.

However, the net benefit is almost always positive. IRAP typically covers 80% of salary costs for approved projects, while SR&ED credits on the unreimbursed portion still apply. The combined recovery rate is higher than either program alone.

Example: An employee earning $100,000 works full-time on an IRAP-funded SR&ED project. IRAP reimburses $80,000. Your SR&ED pool for that employee is reduced to $20,000 (plus the proxy overhead on that amount). But you received $80,000 in IRAP funding plus the SR&ED credit on the remainder — a significantly better outcome than SR&ED alone.

Ignite + SR&ED

Innovate BC's Ignite program provides matching funding for product development. Like IRAP, Ignite funding reduces the SR&ED expenditure pool, but the combination of Ignite grants plus remaining SR&ED credits provides strong total support for early-stage BC tech companies.

IDMTC + SR&ED

BC's Interactive Digital Media Tax Credit (IDMTC) is available to companies developing interactive digital media products (primarily video games, but also certain other digital products). Companies can claim both IDMTC and SR&ED, but not on the same expenditures. You allocate costs to one program or the other based on which provides the higher benefit.

For digital media companies in BC, optimizing the allocation between IDMTC and SR&ED can significantly increase total credits received. This is an area where professional advice pays for itself.

Common SR&ED Mistakes

After helping BC businesses with their funding strategies, we see the same SR&ED mistakes repeatedly. Avoid these:

Not Documenting Contemporaneously

The number one reason claims are reduced or denied. If you cannot show records created at or near the time the work was performed, the CRA may question whether the work happened as described. Start a documentation habit now. Even brief weekly notes describing what technical problems you worked on and what you learned are vastly better than nothing.

Confusing Routine Work with R&D

Using a new technology is not the same as developing one. Implementing a well-documented API, following a vendor's integration guide, or applying established engineering practices to a new project is not SR&ED — even if the project is complex. The question is always: was there a technological uncertainty that required investigation to resolve?

Missing the Filing Deadline

Your SR&ED claim must be filed within 18 months after your fiscal year-end. This is a hard deadline — there is no appeal, no extension, no exception. If your fiscal year ends December 31, 2025, your SR&ED claim for that year must be filed by June 30, 2027. Set a calendar reminder. Better yet, file with your annual tax return so you never risk missing it.

Not Claiming Overhead Allocation

Some businesses only claim direct salary and materials costs, forgetting the proxy overhead. Under the proxy method, you can add 55% of eligible salary costs as overhead without tracking a single receipt. On a $200,000 salary claim, that is an additional $110,000 in eligible expenditures — potentially $49,500 more in refundable credits at the 45% combined rate.

Claiming Too Aggressively

The opposite mistake: claiming routine work as SR&ED invites CRA scrutiny and can result in penalties. If your claim is reviewed and the CRA finds that significant portions were ineligible, it damages your credibility for future claims. Be honest and defensible in what you claim.

Not Separating Eligible from Ineligible Activities Within a Project

Most R&D projects contain a mix of eligible and ineligible activities. The experimental work qualifies; the routine coding, testing, or production that follows does not. Employees who spend 50% of their time on SR&ED-eligible work and 50% on routine work should only have 50% of their salary included in the claim.

DIY vs. SR&ED Consultant: When to Get Help

You can absolutely prepare and file an SR&ED claim yourself. The CRA provides guidance documents, and Form T661 is publicly available. For straightforward claims — a single project with clear technological uncertainty, well-documented work, and modest expenditures — a DIY approach can work.

Consider professional help when:

• This is your first SR&ED claim and you are uncertain whether your work qualifies
• Your eligible expenditures exceed $200,000 and the stakes are high enough to warrant expert preparation
• You have multiple projects with varying degrees of eligibility and need help optimizing the claim
• You have been flagged for a CRA technical review and need help preparing
• You want to combine SR&ED with other programs (IRAP, IDMTC, Ignite) and need to optimize the allocation
• Your company operates in an industry where SR&ED eligibility is less obvious (construction, agriculture, food processing)

SR&ED consultants typically work on a contingency basis (15-30% of the credit received) or a fixed fee. Contingency arrangements mean you pay nothing if the claim is unsuccessful, but the percentage can be significant on large claims. For a comparison of different funding approaches, see our grants vs. loans for BC small business guide. Fixed fees provide more certainty but require payment regardless of outcome.

At GrantEdge, we help BC businesses evaluate whether SR&ED is right for their situation and connect them with qualified SR&ED preparers. If you are unsure where to start, we can help you assess your eligibility and determine the best funding strategy for your business.

Start Claiming What You Are Owed

If your BC business solves technical problems — whether you are writing code, developing products, improving processes, or experimenting with new methods — there is a strong chance you have SR&ED-eligible work. The combined 45% refundable credit for CCPCs, now available on up to $6 million of eligible expenditures thanks to Budget 2026, represents one of the most generous R&D incentives in the world.

The biggest barrier is not eligibility. It is awareness and action. Start documenting your R&D work today. Identify the technological uncertainties you are resolving. Talk to your accountant or an SR&ED specialist about whether a claim makes sense.

And if you are not sure where to start, GrantEdge can help.
