Many Canadian businesses perform experimental work without describing it as research and development. A software company may test architecture that cannot meet a required performance level using standard methods. A manufacturer may conduct trials to overcome material, process or scale-up limitations. A food business may experiment with formulation stability or production constraints.
Where the work meets the statutory requirements, the Scientific Research and Experimental Development tax incentive program may provide a deduction against income and an investment tax credit. The program supports eligible work carried out in Canada, but qualification depends on the nature of the work and the quality of the evidence—not simply on whether the project was innovative or commercially successful.
The two central eligibility requirements
CRA states that eligible work must be conducted in Canada and must satisfy both of the following requirements:
- The work is undertaken for the advancement of scientific knowledge or to achieve a technological advancement.
- The work involves a systematic investigation or search carried out through experiment or analysis.
The technological uncertainty must arise because the existing knowledge base does not make it clear whether or how the objective can be achieved. Normal engineering, routine adaptation or applying known techniques does not become SR&ED merely because it is difficult, costly or new to the company.
What systematic experimentation looks like
CRA describes a systematic investigation as more than an organised development process. The work should identify a problem, form a hypothesis, plan and perform experiments or analysis, and draw logical conclusions from the results.
Failure does not disqualify a project. An unsuccessful trial may still create technological knowledge by demonstrating why an approach does not work. The key is whether the work sought to resolve a technological uncertainty through a disciplined experimental process.
Examples of potentially eligible work
- Developing or materially improving a product, process, material or device where technological limitations cannot be resolved using standard practice.
- Testing alternative designs, algorithms, formulations or process parameters to address a defined uncertainty.
- Experimental scale-up where small-scale results cannot be predictably transferred to commercial conditions.
- Directly supporting engineering, design, computer programming, testing, data collection or mathematical analysis that is commensurate with the core experimental work.
Work that is commonly excluded
CRA excludes activities such as market research, sales promotion, routine quality control, routine testing, commercial production, style changes and routine data collection. Training employees or hiring an expert to apply existing knowledge also does not, by itself, establish SR&ED.
A project may contain both eligible and non-eligible activities. The claim should identify the experimental work precisely rather than treating the entire commercial project as SR&ED.
Financial eligibility and documentation
A technically eligible project must also be connected to allowable expenditures. Depending on the claimant and current rules, relevant costs may include salaries and wages, materials, certain contracts, overhead using an accepted method, and eligible capital or equipment-related amounts.
The strongest claims are built while the work is happening. Useful records may include:
- Project plans, technical objectives and identified uncertainties.
- Design records, test protocols, hypotheses and experiment results.
- Source-code history, issue logs, laboratory notes or engineering reports.
- Time records connecting employees to eligible project work.
- Invoices, contracts and cost-centre reports.
- Evidence showing how failures and iterations influenced the next experiment.
Important 2026 developments
The SR&ED program changed materially in 2026. Legislative amendments that received Royal Assent on 26 March 2026 expanded access to the enhanced investment tax credit, increased the annual expenditure limit for the enhanced 35% credit from CAD 3 million to CAD 6 million, broadened the taxable-capital phase-out range and restored eligibility for certain capital expenditures made after 15 December 2024. The precise benefit still depends on the claimant’s status, tax year and eligible expenditures.
CRA also launched an optional pre-claim approval process on 1 April 2026 for eligible businesses. It allows qualifying businesses to seek a technical determination before beginning the project or incurring costs, giving greater certainty during project planning.
How AccountIF approaches an SR&ED engagement
- Screen projects for genuine scientific or technological uncertainty.
- Interview technical personnel and separate eligible experiments from routine development.
- Build a clear project narrative supported by contemporaneous records.
- Reconcile eligible expenditures to payroll, general-ledger and contract records.
- Prepare the required claim forms and coordinate the claim with the corporation’s tax return.
- Support the client in responding to CRA questions or review requests.
A defensible claim should be accurate, balanced and evidence-based. Overstating routine work can expose the claimant to review risk, while failing to identify genuine experimental work can leave valuable support unclaimed.
