If your company builds, tests or improves products, processes or software, you may be leaving money on the table. The SR&ED tax credit Canada offers to businesses is one of the largest sources of research support in the country. SR&ED stands for Scientific Research and Experimental Development, a federal tax incentive run by the Canada Revenue Agency. This guide covers the program, who qualifies, what you can claim, current rates and key deadlines.
What SR&ED is
SR&ED is a federal tax incentive program run by the Canada Revenue Agency. It rewards Canadian businesses doing research and development in Canada, and it works in two ways. First, you can deduct eligible SR&ED spending from your income. Second, you can earn an investment tax credit (ITC) worth a percentage of your eligible spending. For many small Canadian-controlled private corporations, the credit is refundable: it can be paid out in cash even when the company owes no tax.
Note: SR&ED is not an upfront grant. You do the work, track it, and claim the credit when you file. Good records, kept while the work happens, underpin every successful claim.
Which projects qualify for the SR&ED tax credit Canada program
Not every project counts. To qualify, the work must be done in Canada and meet two tests: it must aim to advance scientific knowledge or achieve a technological advance through systematic investigation in a field of science or technology. In plain terms, you must be resolving a technological unknown, not applying what is already known. Routine engineering, cosmetic changes and work with a readily available answer do not qualify.
The three types of eligible research
Basic research is work that advances scientific knowledge without a specific practical use in mind. Applied research also advances scientific knowledge, but with a practical goal attached. Experimental development is the category most small businesses use: creating new or improved materials, devices, products or processes. Building a prototype, testing a new formulation or writing software that solves a technical problem can all qualify.
Support work can also qualify when it directly supports one of the three categories. The CRA gives engineering, design, operations research, mathematical analysis, computer programming, data collection, testing and psychological research as examples.
Work the CRA rules out
The CRA specifically excludes several kinds of work: market research and sales promotion, quality control and routine testing of materials or products, research in the social sciences or humanities, prospecting or drilling for minerals, petroleum or natural gas, commercial production of a new or improved product, style changes, and routine data collection. Projects in these buckets cannot be claimed, no matter what they cost.
Who can claim
Corporations, individuals carrying on a business, trusts and partners in a partnership can all claim SR&ED incentives for eligible work done in Canada. The enhanced refundable credit goes to most Canadian-controlled private corporations (CCPCs), stand-alone or in an associated group. For tax years that begin after December 15, 2024, eligible Canadian public corporations can earn the enhanced credit as well. Your CCPC status changes your credit rate, so confirm it with your accountant before you plan around a number.
What spending you can claim
Eligible spending covers more than salaries. You can claim:
- Salary and wages for employees directly doing the SR&ED work, apportioned to the time they spent on it
- Materials consumed or transformed during the research
- Payments to contractors who perform SR&ED work for you
- Equipment lease costs, for costs incurred after December 15, 2024
- Overhead under the traditional method, for costs directly tied to the SR&ED
- Third-party payments to approved research bodies such as universities
- Capital spending on depreciable property used more than 90 percent for SR&ED in Canada, for capital costs made after December 15, 2024
Capital spending made before December 16, 2024 cannot be claimed. Our accounting and advisory services can help you sort eligible SR&ED spending from the rest.
Current SR&ED credit rates and limits
The basic investment tax credit rate is 15 percent of eligible spending for every type of claimant. Most CCPCs earn the enhanced rate of 35 percent on eligible spending up to the expenditure limit. Spending above the limit earns the basic 15 percent rate.
The expenditure limit is 6 million dollars a year for tax years beginning after December 15, 2024, and 3 million dollars for earlier years. It phases out as taxable capital employed in Canada rises from 15 million dollars to 75 million dollars in the prior year. Associated companies share one limit, divided using CRA Schedule 49.
Refundability is where small businesses benefit most. For most CCPCs, the 35 percent credit on current spending is fully refundable; on capital spending it is 40 percent refundable. Qualifying corporations can also recover 40 percent of the 15 percent credit earned above the limit, and individuals can recover 40 percent of their 15 percent credit after applying it against tax owed. Other corporations earn a non-refundable 15 percent credit. Unused credits can be carried back up to three years or forward up to twenty years.
For illustration: a small CCPC spends 200,000 dollars on eligible employee salaries for one project in a tax year. At the 35 percent enhanced rate, the credit is 70,000 dollars, and because the spending is current rather than capital, the full amount is refundable. Your own result will depend on your spending mix and corporate status, so treat this as an illustration, not a promise of your result.
SR&ED filing deadlines
SR&ED has a hard filing deadline. For a corporation, the claim must be filed within 12 months after the due date of the corporate tax return. With the T2 due six months after the tax year end, that works out to 18 months after the tax year end. Individuals carrying on a business get 12 months after the T1 due date. The CRA does not accept late SR&ED claims, so calendar this date as soon as your year end passes.
How to file an SR&ED claim
Filing is straightforward if your records are in order:
- Identify your SR&ED projects and the technological uncertainties each one set out to resolve.
- Document the work as it happens: hypotheses, tests, results and the time your people spent. Contemporaneous records carry the most weight.
- Complete Form T661, which describes the work and reports the spending, and file it with your tax return. Corporations calculate the credit on Form T2SCH31, and individuals use Form T2038-IND.
- File with your original return or an amended return, using CRA-certified tax software or by mail.
Mistakes that shrink or sink claims
- Weak time tracking, so salary claims cannot be backed up.
- Missing the 18-month filing deadline.
- Assuming the work had to succeed. Failed experiments can still qualify, because the CRA looks for a systematic search, not a successful outcome.
