Canada SR&ED Tax Incentive & Grants Guide 2026
Understand Canada's 2026 SR&ED program, including the 35% enhanced federal credit, new $6 million expenditure limit, taxable-capital phase-out, qualifying R&D work, eligible expenditures, government assistance, refundability and Form T661.
1. What Is the SR&ED Program in 2026?
Scientific Research and Experimental Development (SR&ED) is Canada's federal tax-incentive program for qualifying research and development work conducted in Canada. The program provides investment tax credits (ITCs) to eligible claimants that incur qualified SR&ED expenditures. For tax years beginning after December 15, 2024, legislative changes increased the enhanced expenditure limit to $6 million, expanded the enhanced rate to eligible Canadian public corporations, restored qualifying SR&ED capital expenditures and broadened the taxable-capital phase-out range.
Key Framework Highlights:
- The enhanced federal ITC rate is 35% on qualified SR&ED expenditures within the applicable enhanced expenditure limit.
- For tax years beginning after December 15, 2024, the maximum enhanced expenditure limit is $6 million.
- The basic federal ITC rate is 15% on qualified SR&ED expenditures outside the enhanced-rate regime.
- Most qualifying CCPCs can earn the enhanced 35% rate; eligible Canadian public corporations can also qualify for the enhanced rate for newer tax years.
- Qualifying SR&ED capital expenditures made after December 15, 2024 can again qualify for SR&ED incentives.
- The SR&ED rate and refundability are separate concepts: earning a 35% ITC does not mean every dollar of that ITC is automatically refundable in cash.
Action Checklist:
- Identify the technological problem or uncertainty the business was attempting to resolve.
- Document the systematic investigation or experimentation performed.
- Separate eligible SR&ED work from routine commercial development and ordinary business activity.
- Track eligible expenditures by project and claimant.
- Determine the applicable ITC rate, expenditure limit and refundability rules.
- File Form T661 and the applicable investment-tax-credit schedule by the SR&ED reporting deadline.
2. 2026 SR&ED ITC Rates, Expenditure Limits and Refundability
The federal SR&ED system distinguishes between the enhanced 35% rate and the basic 15% rate. It also separately determines whether an earned ITC is refundable. For the newer tax years, most qualifying CCPCs can earn a 35% enhanced ITC up to the expenditure limit. Eligible Canadian public corporations can also earn the 35% enhanced rate. Refundability then depends on the claimant category and the type of qualified expenditure.
| Claimant / Situation | Rate Within Enhanced Limit | General Refundability | Rate Above Enhanced Limit |
|---|---|---|---|
| Qualifying CCPC | 35% | Current expenditures: generally 100% refundable; capital expenditures: 40% refundable | 15% basic-rate ITC; refundability depends on claimant status |
| Other CCPC | 35% | 35% enhanced ITC may be refundable under the applicable CCPC rules; capital and basic-rate amounts require separate analysis | 15% basic-rate ITC can be non-refundable for a CCPC that does not meet the relevant qualifying status |
| Excluded corporation | 35% | 40% refund rate on the applicable ITC | 15% ITC with applicable refund rules |
| Eligible Canadian Public Corporation (ECPC) | 35% | Current expenditures: generally 100% refundable; capital expenditures: 40% refundable | 15% basic-rate ITC |
| Other corporation | 15% | Generally non-refundable | 15% non-refundable |
| Individuals / certain trusts / unincorporated claimants | 15% | Refundability can be 40% subject to the applicable rules | 15% with applicable claimant-specific refund rules |
3. The New $6 Million Enhanced Expenditure Limit
For tax years beginning after December 15, 2024, the maximum expenditure limit used for the enhanced 35% SR&ED ITC is $6 million. The $6 million amount is an enhanced-rate limit, not a maximum amount of R&D that a business may claim. Qualified expenditures above the expenditure limit can generally continue to earn the basic 15% ITC.
Key Framework Highlights:
- $6 million is the maximum enhanced-rate expenditure limit for the applicable newer tax years.
- The limit is not a cap on total SR&ED expenditures.
- Qualified expenditures above the enhanced limit can generally earn the basic 15% ITC.
- For associated CCPCs, the expenditure limit is calculated at the group level and allocated among associated corporations.
- For consolidated groups of eligible Canadian public corporations, the applicable group rules also affect the limit.
4. Taxable Capital Phase-Out of the Enhanced Limit
The enhanced expenditure limit can be reduced based on taxable capital employed in Canada. For CCPCs and the newer enhanced-credit regime, the phase-out range has been expanded: for tax years beginning after December 15, 2024, the expenditure limit generally begins to decrease when the relevant prior-year taxable capital employed in Canada reaches $15 million and becomes nil at $75 million.
| Relevant Prior-Year Taxable Capital | Enhanced Expenditure Limit | General Effect |
|---|---|---|
| Below $15 million | Up to $6 million, subject to other rules | No taxable-capital reduction from this test |
| $15 million to below $75 million | Reduced on a phase-out basis | Enhanced 35% limit declines as taxable capital increases |
| $75 million or more | Nil under this phase-out | No enhanced-rate expenditure limit remains from this test |
5. What R&D Work Qualifies as SR&ED?
The key SR&ED question is whether the work meets the legislative definition of scientific research and experimental development. In practical terms, eligible work seeks technological advancement through systematic investigation or search in a field of science or technology and addresses technological uncertainty. Routine engineering, ordinary commercial development, market research or work that simply applies established knowledge without resolving technological uncertainty may not qualify.
6. Technical Documentation CRA Expects
Good SR&ED documentation connects the technical problem, experimental work and resulting knowledge to the expenditures claimed. CRA can review both the technical eligibility of the project and the financial eligibility of the expenditures. Documentation created contemporaneously is generally much stronger than records reconstructed years later.
| Record | Useful Evidence | Why It Matters |
|---|---|---|
| Technical project description | Problem, uncertainty, objective, hypothesis and advancement sought | Shows why ordinary knowledge or practice was insufficient |
| Experiment records | Test plans, prototypes, iterations, measurements and failures | Shows systematic investigation |
| Code and technical artifacts | Source-control history, architecture documents, test results and benchmark data | Links actual technical work to SR&ED activities |
| Employee time records | Timesheets, project allocations and payroll records | Supports eligible salary calculations |
| Contract records | Statements of work, invoices, payment evidence and technical deliverables | Supports contract-expenditure calculations |
| Financial records | General ledger, invoices, payroll, materials and asset records | Supports qualified expenditures |
Action Checklist:
- Record the technological uncertainty before or during the experimental work.
- Maintain project-level timesheets or another credible allocation method.
- Preserve source-control history, technical notes and experiment results.
- Keep invoices and payment records for contractors and materials.
- Document government assistance as soon as it is received or becomes reasonably expected.
- Reconcile technical project records to the financial amounts reported on Form T661.
7. Eligible SR&ED Expenditures
Qualified SR&ED expenditures can include eligible salaries and wages, certain materials consumed or transformed in SR&ED, qualifying contract expenditures, and certain other expenditures recognized by the legislation. The exact amount that enters the ITC calculation depends on the expenditure category, payment timing, relationship between parties, government assistance and the method used to calculate overhead.
| Expenditure | General SR&ED Treatment | Key Limitation |
|---|---|---|
| Employee salaries and wages | Can be qualified to the extent attributable to eligible SR&ED work | Must allocate the employee's actual SR&ED work and apply specified-employee and other rules. |
| Arm's-length SR&ED contracts | Generally 80% of qualifying contract amounts enters qualified expenditures under the specified rule | Not every consultant invoice is an SR&ED contract. |
| Materials | Certain materials consumed or transformed in SR&ED can qualify | Materials sold, leased or incorporated in ordinary commercial output can require different treatment. |
| SR&ED capital expenditures | Qualifying capital expenditures made after December 15, 2024 can qualify | Special rules apply; capital ITCs have different refundability treatment. |
| Overhead | Can be calculated under the traditional method or the prescribed proxy method where eligible | The PPA uses a prescribed formula and salary base. |
8. Employee Salaries and the Prescribed Proxy Amount (PPA)
Claimants can generally choose between the traditional method for certain overhead expenditures and the proxy method using a prescribed proxy amount (PPA). Under the current PPA policy, the PPA is generally calculated as 55% of the eligible SR&ED portion of salaries and wages of employees directly engaged in SR&ED, subject to the detailed statutory restrictions.
Key Framework Highlights:
- The current prescribed proxy amount percentage is 55%.
- Specified-employee rules can limit the salary amount used in the calculation.
- The traditional method and proxy method have different expenditure requirements.
- The PPA should not be described as a separate 55% tax credit.
9. SR&ED Contractor and Subcontractor Rules
Contract payments can qualify when the work is SR&ED performed on behalf of the claimant and the statutory conditions are satisfied. CRA's current T661 guidance generally limits qualifying arm's-length contract payments and certain third-party payments to 80% for purposes of qualified SR&ED expenditures. The exact treatment differs for related parties and other categories of contract expenditures.
Key Framework Highlights:
- 80% is generally the qualified-expenditure percentage for specified arm's-length SR&ED contract payments.
- A contractor performing ordinary commercial development does not become an SR&ED contractor merely because the invoice uses the words 'R&D.'
- The contract should clearly identify the experimental or technological work being performed.
- Payment timing matters, including CRA's rules concerning unpaid contract expenditures.
- Related-party contract arrangements require separate analysis under the SR&ED rules.
10. SR&ED Capital Expenditures After December 15, 2024
One of the major changes applicable to newer tax years is the restoration of SR&ED capital expenditure eligibility. Qualifying capital expenditures made after December 15, 2024 can again be included in SR&ED incentives under the new rules. This is important for businesses developing or testing technology using qualifying equipment and other capital property.
Key Framework Highlights:
- Capital SR&ED expenditures made after December 15, 2024 can qualify.
- Capital expenditures made before December 16, 2024 remain subject to the previous exclusion.
- The treatment of capital ITCs differs from current-expense ITCs for refundability.
- Assets must satisfy the SR&ED legislative requirements; buying ordinary equipment does not automatically create a qualifying SR&ED expenditure.
- The available-for-use rules can affect whether a capital expenditure is treated as made after the legislative effective date.
11. Government Grants, IRAP and Other Assistance
Government assistance does not automatically prevent R&D work from qualifying for SR&ED, but assistance can reduce the qualified expenditures or ITC that can be claimed. CRA specifically states that funding such as NRC-IRAP reduces the amount of SR&ED ITC that can be earned. The reduction depends on the nature, amount, timing and relationship of the assistance to the SR&ED expenditures.
Key Framework Highlights:
- NRC-IRAP funding can reduce the SR&ED ITC that can be earned.
- Government assistance and non-government assistance related to SR&ED are considered under the qualified-expenditure rules.
- Assistance that has been received, is receivable, or can reasonably be expected can be relevant depending on the statutory requirements.
- Provincial or territorial R&D tax credits can also affect SR&ED qualified expenditures.
- The same project can potentially receive multiple forms of support, but the tax incentives must be calculated after applying the relevant assistance rules.
12. SR&ED Filing Deadline and T661
For corporations, the SR&ED reporting deadline is generally 18 months after the end of the tax year in which the expenditures were incurred. CRA describes this as 12 months after the T2 filing due date. Corporations should generally file the SR&ED claim with the T2 rather than waiting for the full 18-month period, but the additional reporting window can be used to identify expenditures on the prescribed forms.
| Claimant | Income Tax Return Due | SR&ED Reporting Deadline |
|---|---|---|
| Corporation | Generally 6 months after tax year-end | Generally 18 months after tax year-end |
| Individual carrying on business | Generally June 15 of the following year | Generally 17.5 months after calendar year-end |
| Trust | Generally 90 days after tax year-end | Generally 15 months after tax year-end, subject to the applicable rules |
Action Checklist:
- File the T2 by its normal six-month deadline.
- Include Form T661 and the applicable ITC schedule with the return when possible.
- Do not wait unnecessarily for the 18-month SR&ED reporting deadline.
- If an eligible expenditure was omitted, identify it on the prescribed form before the applicable SR&ED reporting deadline.
- Retain the technical and financial supporting documentation after filing.
13. Which Forms Are Used for an SR&ED Claim?
A corporate claimant normally uses Form T661 to report the SR&ED expenditures and project information. Schedule T2SCH31 is used to calculate the corporate investment tax credit. Individuals and certain other claimants use Form T2038(IND) for the investment tax credit rather than the corporate Schedule T2SCH31. Provincial or territorial R&D credits can require additional schedules.
| Claimant | Primary SR&ED Expenditure Form | ITC Reporting |
|---|---|---|
| Corporation | T661 | Schedule T2SCH31 and applicable T2 reporting |
| Individual | T661 | Form T2038(IND) and applicable T1 reporting |
| Partnership | T661 as applicable to the claim | Allocated ITC follows the partnership/partner rules |
14. Provincial and Territorial R&D Tax Credits
Federal SR&ED is only one potential layer of R&D support. Provinces and territories can have separate R&D credits with their own eligibility conditions, rates, expenditure definitions and filing schedules. A business should not assume that the provincial credit is simply an additional percentage applied to the same federal number without adjustment.
Action Checklist:
- Identify the province or territory where the R&D is performed and where the claimant carries on business.
- Review the provincial or territorial program separately from federal SR&ED.
- Determine whether the provincial credit is refundable, non-refundable or partially refundable.
- Apply any rule requiring provincial assistance to reduce federal SR&ED qualified expenditures.
- File all required provincial schedules with the applicable provincial income-tax return.
15. 2026 SR&ED Claim Preparation Roadmap
The strongest SR&ED claim connects technical facts to financial numbers. A successful process starts before year-end rather than reconstructing the project after the T2 deadline.
Action Checklist:
- Create a project register identifying each potentially eligible SR&ED project.
- For every project, document the technological uncertainty and technological advancement being pursued.
- Maintain experiment logs, test results, source-code history and engineering records.
- Track employee SR&ED time by project throughout the year.
- Separate qualifying contract work from routine outsourcing.
- Track materials, qualifying capital expenditures and other project costs.
- Record government grants, IRAP support and other assistance affecting the work.
- Choose the appropriate overhead calculation method.
- Calculate the appropriate expenditure limit and taxable-capital reduction.
- Determine the enhanced and basic ITC portions.
- Determine how much of the ITC is refundable.
- Complete T661 and the appropriate ITC schedule.
- Reconcile the T661 expenditure totals to the general ledger and payroll records.
- File with the T2 as early as practical and no later than the SR&ED reporting deadline.
16. Common SR&ED Mistakes to Avoid
| Mistake | Why It Is a Problem | Better Practice |
|---|---|---|
| Using the old $3 million limit | The 2026 regime can provide a $6 million enhanced limit | Check the tax-year start date and current limit. |
| Calling every 35% ITC fully refundable | Refundability depends on claimant and expenditure type | Calculate ITC rate and refundability separately. |
| Treating all software development as SR&ED | Routine development may not address technological uncertainty | Document the specific technological problem and experimentation. |
| Claiming all contractor invoices at 80% | Only specified qualifying contract expenditures receive the 80% treatment | Classify each contract under CRA's SR&ED rules. |
| Ignoring grants until after filing | Assistance can reduce qualified expenditures and ITC | Track funding when received, receivable or reasonably expected. |
| Reconstructing all technical evidence after year-end | Weak contemporaneous documentation can make technical eligibility harder to establish | Maintain project records throughout the work. |
| Assuming federal and provincial R&D rules are identical | Provincial credits have separate legislation and conditions | Prepare a separate federal and provincial analysis. |
