The SR&ED (Scientific Research & Experimental Development) program is Canada’s largest federal tax incentive providing Investment Tax Credits (ITCs) of up to 35% refundable on qualifying R&D expenditures for CCPCs. For CCPCs, the first $3 millions of qualifying expenditures receives a 35% refundable ITC meaning CRA pays the credit in cash even if no tax is owing. For other corporations, a 15% non-refundable ITC applies. SR&ED claims are filed with the T2 return using Form T661 and T2 Schedule 31. DKP Global identifies qualifying activities and prepares SR&ED claims for Canadian technology and innovation companies.

What is the SR&ED Program and Why Most Companies Underuse It
The Scientific Research & Experimental Development (SR&ED) program is the Canadian federal government’s largest research and development tax incentive. It provides Investment Tax Credits (ITCs) refundable for CCPCs on expenditures related to qualifying R&D work performed in Canada. The program has been in place since 1985 and distributes approximately $3–4 billion in ITCs annually to over 20,000 Canadian companies.
Despite its size and generosity, SR&ED is chronically underutilized. The primary reason: most business owners do not realize that their work qualifies. The term “Scientific Research” triggers images of university labs and pharmaceutical trials but the vast majority of SR&ED claims are filed by technology companies, software developers, manufacturers, food producers, and engineering firms for development work they do every day. If your company is building software and encountering technical problems that require experimentation to solve, you are likely doing SR&ED work. If your manufacturing process is being improved through systematic testing, that may qualify. If you are developing a new product that does not yet exist and requires iterative prototyping, that is SR&ED.
The key distinction is not what industry you are in it is whether your work involves technological uncertainty that requires a systematic investigation. DKP Global screens every client’s activity annually for SR&ED potential, because the refundable credit on $500,000 of qualifying expenditure is $175,000 in cash from CRA money that is available every year to qualifying companies whether or not they are profitable.
SR&ED Tax Credit Rates CCPC vs Non-CCPC 2026
| Taxpayer Type | ITC Rate | Refundable? | Maximum Enhanced Rate | Notes |
| CCPC first $3M of qualifying expenditures | 35% | Yes, fully refundable | $3,000,000 × 35% = $1,050,000 refundable ITC | Most valuable SR&ED category cash payment even if no tax owing |
| CCPC qualifying expenditures over $3M | 15% | No non-refundable (can carry forward) | Applied to amounts above the $3M enhanced limit | Large CCPCs with significant R&D programs |
| Non-CCPC (foreign-controlled, public corps) | 15% | No non-refundable | No enhanced rate available | Still valuable offsets corporate tax otherwise owing |
| Canadian-controlled partnership | 35% (CCPC partner portion) | Partially refundable | Based on CCPC partner’s share of partnership | Partnerships pass SR&ED credits to partners |
| $3M limit reduction taxable income | Enhanced rate phases out when prior year taxable income exceeds $500,000 | Proportional reduction eliminated at $800,000 taxable income | At $800K prior year income, only 15% ITC available | Growing businesses should track when they approach this threshold |
| $3M limit reduction taxable capital | Enhanced rate phases out when prior year taxable capital (associated group) exceeds $10M | Eliminated at $50M taxable capital | Large corporations lose the enhanced refundable rate | Rare for genuine startup/SME companies |
The 35% refundable ITC for CCPCs is one of the most generous R&D incentives in the world. For a CCPC spending $500,000 on qualifying SR&ED activities wages, contractors, materials, equipment costs related to the R&D CRA pays $175,000 in cash within 8 weeks of filing the T2. This cash is available regardless of whether the corporation is profitable. For a startup burning through its initial investment while building a product, this refundable credit is a meaningful cash injection that many founders do not know exists.
What Qualifies for SR&ED Eligibility Criteria
CRA defines SR&ED as systematic investigation or search carried out in a field of science or technology by means of experiment or analysis to advance knowledge or achieve a technological advancement and eliminate a technological uncertainty. There are three types of qualifying work:
| SR&ED Category | Definition | Examples |
| Basic Research | Work undertaken to advance scientific knowledge without a specific practical application in view | University partnerships, fundamental chemistry research rare in SME context |
| Applied Research | Work undertaken to advance scientific knowledge with a specific practical application in view | Developing a new material for a specific product application; testing a biological compound for a particular use |
| Experimental Development | Work that uses scientific or technological knowledge to develop new or improve existing materials, devices, products, or processes | Building new software with novel algorithms; developing a new manufacturing process; creating a new product where the technical approach is uncertain |
The two core requirements for SR&ED eligibility are: (1) Technological Uncertainty there must be a genuine technical problem or question that cannot be resolved through existing knowledge alone, requiring experimentation or analysis; and (2) Technological Advancement the work must contribute to advancing the state of knowledge in a field of science or technology. The uncertainty does not need to be global it is sufficient that it is uncertain to a competent professional in the relevant field.
Examples of Work That Typically Qualifies
- Software development: Developing novel algorithms, new data structures, or computational methods where the technical approach is uncertain NOT routine software development using established techniques
- Product development: Iterative prototyping where the technical approach is experimental and the outcome is uncertain NOT straightforward product assembly or customization
- Process improvement: Systematic testing of manufacturing parameters to achieve a technical improvement not achievable through existing documented methods
- Formulation development: Developing new chemical formulations, food products, or materials where the interaction of components creates technological uncertainty
Examples of Work That Does NOT Qualify
- Routine software development using established languages, frameworks, and techniques even if it takes a long time
- Market research, customer surveys, or sales prospecting even if data-driven
- Routine quality assurance testing of an established product
- Style, aesthetic, or UX design work even for technology products
- Business process improvement that does not involve technological advancement
What Expenditures Are Eligible SR&ED-Eligible Costs
| Expenditure Type | SR&ED Eligible? | Deductibility | Notes |
| Employee wages (SR&ED work only) | Yes 100% of time spent on qualifying SR&ED | 100% included in SR&ED pool | Require time-tracking records to support the SR&ED portion of each employee’s time |
| Contract payments (arm’s-length) | Yes 80% of payments to arm’s-length contractors | 80% of contract costs included in SR&ED pool | Subcontracted R&D work must be for qualifying SR&ED activities |
| Contract payments (non-arm’s-length) | Yes, lesser of cost or FMV | Lesser of cost or FMV | Related party contracting requires transfer pricing consideration |
| Materials consumed in SR&ED | Yes, direct material costs | 100% of materials used and consumed in SR&ED | Keep separate inventory tracking for SR&ED materials |
| Equipment used for SR&ED | Partial capital expenditures receive ITC, but capital cost also claimed as CCA | ITC on capital + CCA deduction | Dedicated SR&ED equipment vs shared equipment apportionment required |
| Overhead expenses (proxy method) | Yes, if using proxy method | 55% of SR&ED wages as a proxy for overhead costs | Avoids detailed overhead tracking recommended for most small companies |
| Overhead expenses (traditional method) | Yes, if using traditional method | Actual SR&ED-related overhead costs | More documentation-intensive only beneficial if actual overhead exceeds 55% of wages |
How to File an SR&ED Claim T661 and T2 Schedule 31
| Step | Action | Details |
| 1 | Identify qualifying SR&ED activities during the year | Review all projects, products under development, and process improvements assess each for technological uncertainty and systematic investigation |
| 2 | Document the SR&ED work | For each qualifying project: describe the technological uncertainty, the hypothesis tested, the systematic investigation conducted, and the technological advancement achieved or attempted |
| 3 | Compile SR&ED expenditure records | Track employee time on SR&ED activities (timesheets by project), contractor invoices for SR&ED work, materials consumed in SR&ED, equipment used in SR&ED |
| 4 | Choose calculation method Proxy or Traditional | For most SMEs: the Proxy Method is simpler 55% of SR&ED employee wages as a proxy for overhead. Choose Traditional only if actual overhead significantly exceeds 55% of wages. |
| 5 | Complete Form T661 (SR&ED Expenditures Claim) | T661 is the SR&ED technical and financial form Part 2 (project descriptions), Part 3 (expenditure calculations), Part 4 (ITC calculation). One form per claim year. |
| 6 | Complete T2 Schedule 31 (Investment Tax Credit) | Schedule 31 calculates the ITC applying the 35% (CCPC) or 15% (other) rate to qualifying expenditures, determining refundable vs non-refundable portions. |
| 7 | File with T2 by the 12-month deadline | SR&ED claims must be filed within 12 months of the T2 filing deadline for a December 31 fiscal year, this means by June 30 of the following year (T2 deadline) plus potentially an additional period. Confirm exact deadline at filing time. |
| 8 | CRA review and ITC payment | CRA reviews the claim may conduct a technical or financial review. For clean claims, refundable ITCs are typically paid within 120 days of filing. |
SR&ED Claim Method Proxy vs Traditional
| Factor | Proxy Method | Traditional Method |
| Overhead included | 55% of SR&ED labour costs flat proxy rate | Actual SR&ED overhead expenses tracked and claimed |
| Documentation required | SR&ED employee wages + time records | Actual overhead expenses with SR&ED apportionment support |
| Complexity | Simple one calculation | More complex requires overhead cost tracking by project |
| Best for | Most SMEs with standard overhead structures | Companies where actual SR&ED overhead significantly exceeds 55% of wages manufacturing, lab-intensive research |
| Switching allowed? | Yes, can switch methods year to year | Yes, DKP Global evaluates which method is more favorable each year |
The Proxy Method is the right choice for most small Canadian technology and software companies. It simplifies the claim process significantly you only need to track employee time on SR&ED activities, contractor invoices for SR&ED work, and materials consumed. The 55% proxy overhead rate is applied automatically without tracking utilities, rent, office supplies, or other overhead by project. DKP Global uses the Proxy Method for the vast majority of SR&ED clients and evaluates the Traditional Method only where a client has unusually high directly attributable overhead.
SR&ED Audits What CRA Reviews and How to Prepare
CRA has dedicated SR&ED reviewers who conduct both technical reviews (does the work qualify?) and financial reviews (are the expenditure claims supported?). SR&ED claims are significantly more likely to be reviewed than standard T2 returns particularly for first-time claimants and large claims.
Technical Review
A technical reviewer assesses whether the claimed projects meet the SR&ED eligibility criteria technological uncertainty, systematic investigation, and technological advancement. They may ask for: project technical reports, meeting minutes, design documents, testing protocols, experimental results, version history for software, and personnel qualifications. The most common technical review issue is a project description that is too vague describing what was built rather than what was technically uncertain and how it was investigated.
Financial Review
A financial reviewer assesses whether the claimed expenditures are properly documented and correctly calculated. They will ask for: employee time records (timesheets) supporting the SR&ED portion of each employee’s time, contractor invoices with SR&ED work descriptions, material purchase records, and evidence that the claimed percentages of each employee’s time actually applied to SR&ED. The most common financial review issue is inadequate time-tracking records.
How to Be Audit-Ready
- Maintain contemporaneous records: Document SR&ED activities as they happen not at year end. Meeting minutes, experimental notes, version histories, and test results are far more credible when created in real time.
- Keep detailed timesheets: Every employee who works on SR&ED should maintain weekly timesheets showing hours by project including non-SR&ED projects. The SR&ED portion of each employee’s time must be defensible.
- Write strong project descriptions: Each T661 project description should address the specific technological uncertainty (what did you not know?), the hypothesis tested, the systematic experiments conducted, and the result (advancement achieved or uncertainty eliminated).
Separate SR&ED materials: Maintain separate inventory records for materials consumed in SR&ED experiments distinguishing from materials used in production.
Common SR&ED Mistakes That Cost Companies Money.
| Mistake | What It Costs | How to Avoid |
| Not claiming SR&ED at all | Missing $50,000–$1,000,000+ in annual refundable credits leaving cash on the table | DKP Global screens every client’s activity annually many companies qualify without knowing it |
| Filing too late past the 12-month deadline | SR&ED claims filed after the deadline are rejected entirely no ITC available | DKP Global tracks SR&ED deadlines alongside T2 filing deadlines same calendar |
| Project descriptions too vague | CRA denies the technical review project description says what was built, not what was technically uncertain | DKP Global prepares detailed project descriptions using CRA’s eligibility framework technological uncertainty, systematic investigation, advancement |
| No time-tracking records | Financial review denies employee wage claims insufficient documentation | DKP Global implements a simple project time-tracking system at the start of the year for SR&ED-active clients |
| Including non-qualifying work | CRA adjusts the claim disallows routine development work mixed with qualifying work | DKP Global separates qualifying SR&ED activities from routine development in each project description |
| Wrong method selection | Traditional method chosen without evaluating whether actual overhead exceeds 55% may claim less than Proxy would have given | DKP Global calculates both methods annually and selects the more favorable one |
How DKP Global Prepares SR&ED Claims
DKP Global provides end-to-end SR&ED claim preparation from activity identification to T661 preparation to CRA review support. Our process:
- Annual SR&ED screen: Every October, we review each active client’s development activities for the year asking the right questions to identify qualifying work that the client may not have recognized as SR&ED.
- Project documentation: For qualifying activities, we prepare detailed T661 project descriptions written in the specific technical language CRA expects, addressing uncertainty, hypothesis, investigation, and advancement.
- Expenditure compilation: We compile employee time records, contractor invoices, and materials costs for each qualifying project calculating the SR&ED expenditure pool using the Proxy Method.
- ITC calculation: We complete T2 Schedule 31applying the 35% CCPC rate (or 15% for non-CCPCs), calculating the refundable and non-refundable portions, and determining the net ITC claim.
- T661 and T2 filing: SR&ED T661 and Schedule 31 are filed as part of the annual T2 not as a separate submission. We include all SR&ED schedules in the NETFILE T2 submission.
- CRA review support: If CRA conducts a technical or financial review of the SR&ED claim, DKP Global prepares responses and additional documentation on the client’s behalf defending the claim without the client having to communicate directly with CRA reviewers.
DKP Global has identified SR&ED eligibility in client activities across technology, software development, food manufacturing, agricultural innovation, and specialized engineering. The most commonly missed SR&ED opportunity is in Canadian technology startups and software companies where founders assume that only hardware or pharmaceutical companies qualify. If your developers are solving technical problems that require iterative experimentation not just following established frameworks, they are likely doing SR&ED work. DKP Global turns that work into a refundable credit that funds the next cycle of development.

Frequently Asked Questions SR&ED Tax Credit Canada
SR&ED (Scientific Research & Experimental Development) is Canada’s federal R&D tax incentive program. Any Canadian company that performs qualifying R&D activities in Canada can claim SR&ED credits including technology companies, software developers, manufacturers, food companies, agricultural businesses, and engineering firms. The common misconception is that only pharmaceutical or university-affiliated companies qualify. In reality, most SR&ED claims are filed by SMEs doing systematic development work.
For CCPCs (Canadian-Controlled Private Corporations): 35% refundable ITC on the first $3 million of qualifying SR&ED expenditures. This means CRA pays 35 cents for every dollar of qualifying R&D spending as a cash refund, even if the corporation owes no tax. The $3M enhanced rate phases out based on prior year taxable income ($500K–$800K) and taxable capital ($10M–$50M). For non-CCPC corporations: 15% non-refundable ITC.
Qualifying SR&ED must involve: (1) technological uncertainty a technical problem or question that cannot be resolved by current knowledge alone, requiring experimentation; (2) systematic investigation a formal, hypothesis-driven approach to resolving the uncertainty; and (3) technological advancement the work must aim to advance the state of knowledge in a field of science or technology. Routine software development using established frameworks does not qualify; developing novel algorithms to solve a technical problem that existing approaches cannot solve does.
SR&ED claims are filed with the annual T2 corporate tax return using Form T661 (Scientific Research and Experimental Development Expenditures Claim) and T2 Schedule 31 (Investment Tax Credit). T661 contains the technical project descriptions and expenditure calculations; Schedule 31 calculates the ITC. The claim must be filed within 12 months of the T2 filing deadline. DKP Global prepares both T661 and Schedule 31 as part of the annual T2 engagement.
Eligible SR&ED expenditures include employee wages for time spent on qualifying SR&ED activities (require time-tracking records), 80% of arm’s-length contractor payments for SR&ED work, materials consumed in the SR&ED process, and overhead expenses (either the actual SR&ED overhead or a proxy of 55% of SR&ED wages). Capital equipment used for SR&ED generates an ITC but is not included in the expenditure pool it is claimed separately on Schedule 31.
SR&ED claims must be filed within 12 months of the corporation’s T2 filing deadline. For a December 31 fiscal year, the T2 deadline is June 30 making the SR&ED deadline June 30 of the following year. For a March 31 fiscal year, the T2 deadline is September 30 SR&ED deadline is September 30 of the following year. Missing this deadline is fatal late SR&ED claims are rejected entirely. DKP Global tracks SR&ED deadlines as part of every client’s tax calendar.
