Introduction
In Canada, tax is paid at both federal and provincial (i.e. state) levels of government. Both the federal government and most provincial governments provide funding for scientific and technological R&D through a system of tax credits.
The official title of this system of R&D tax credits is the Scientific Research & Experimental Development tax credit, abbreviated SR&ED. The SR&ED program is administrated by the Canada Revenue Agency (CRA).
All taxpayers anywhere in Canada are eligible to receive R&D tax credits at the federal level. Eligibility for R&D tax credits at the provincial level is predicated on two considerations: first the province must have an R&D credit and second, you must be a taxpayer in that province. In addition to being done by a Canadian taxpayer, the R&D work must be done in Canada.
“Taxpayer” means:
- Individuals
- Partnerships of individuals and / or corporations
- Private corporations
- Public corporations (meaning its shares are traded on a public stock exchange)
In provinces with an R&D tax credit, eligibility for the provincial tax credit is automatically triggered by eligibility at the federal level. However, some provinces do not allow the same full range of expenditure types as are eligible at the federal level.
Depending on whether the taxpayer is a corporation or not, and also on its ownership and corporate structure, these R&D tax credits benefit the taxpayer in either of two ways:
- Reduced taxes payable
- A cash refund even if no taxes payable
In an average year, this system of funding contributes approximately $4.5 billion to private sector R&D in Canada.
Although operationally administered by CRA, the SR&ED rules are codified in legislation. While the rules are subject to adjustment from time to time, Canada’s SR&ED program is permanent and has been in continuous operation for over 25 years.
Key Concepts
- The SR&ED benefit applies to the cost of conducting a systematic investigation in Canada that is aimed at overcoming a technological obstacle in order to achieve a scientific or technological advancement. Successful achievement of an outcome is not a criterion to qualify for the benefit.
- SR&ED benefits are allowed in addition to the normal business expense deduction that a Canadian taxpayer would otherwise be allowed for R&D expenditures.
- Most small Canadian Controlled Private Corporations (“CCPC”s) and some public corporations that are Canadian-owned / controlled Eligible Canadian Public Corporations (“ECPC”s) can receive SR&ED benefits paid as a cash refund calculated of up to 35% of the eligible expenditures – even if the taxpayer has no taxable income or tax payable. Canada is one of the very few countries in the world to offer an R&D tax credit with this type of “cash refund” benefit.
- For large and foreign-owned corporations (“non-CCPC”s), SR&ED benefits are calculated as 15% of eligible expenditures in the form of an investment tax credit (ITC) which can only be used to reduce taxes payable. This ITC can either be applied immediately to reduce taxes in the current year, applied retroactively up to 3 years back or “saved” and carried forward up to 20 years. This allows large and foreign-owned corporations to effectively monetize their SR&ED benefits as / when they become taxable.
- Individuals, un-incorporated businesses and partnerships are also eligible to receive a cash benefit, but at a significantly lower rate than CCPCs or ECPCs. Therefore, organizations of these types that undertake R&D should consider incorporating themselves as a private corporation.
- Wages, materials, contracted R&D services and overhead are all eligible SR&ED expenditures at the federal level. R&D-use capital equipment purchased after December 15, 2024 is also eligible. However, provincial level SR&ED benefits may or may not apply to all of these categories e.g. some provinces do not cover materials or overhead.
- There is no upper limit on the amount of SR&ED benefit that can be claimed. However, for CCPCs and ECPCs the 35% rate is diminished and becomes only partially refundable on expenditures in excess of the expenditure limit which is currently $6M. However, this $6M limit can itself be ground down if the corporation’s prior year taxable capital (for CCPCs) or its average gross revenue over prior three years exceeds $15M (for ECPCs and CCPCs). This grind down occurs on a straight-line basis such that at $75M the 35% is reduced to 15%, which is 40% refundable for CCPCs and 0% refundable for ECPCs.
- Government and non-Government “Assistance” acts to reduce SR&ED eligible expenditures. Assistance includes any monies provided to the taxpayer to reduce out of pocket cost of performing the SR&ED. This includes payments from other companies, government grants (IRAP) and loans from government agencies (ACOA, FedDev, etc.).
- Income received from the sale of R&D results (e.g. taxpayer is selling an R&D service) may act to reduce the eligible SR&ED expenditure. The reduction is significantly affected by the nature of the contract between the R&D seller and the R&D buyer.
- Only R&D work carried out in Canada is eligible for SR&ED. Recent amendments to legislation make allowance for up to 10% of the wage expenditures to be for work outside Canada, but only if that work is directly associated with (and vital) to an SR&ED project undertaken by the taxpayer in Canada.
- To claim SR&ED, the taxpayer must identify specific projects and associated expenditures that meet CRA’s definition of eligible R&D work.
- The claim must include a detailed written technical description for each project being claimed. This technical description must include both a description of the activity (i.e. the systematic investigation) and a justification of the project’s eligibility in terms of technological advancement and uncertainty.
- Claims must be filed within 18 months of fiscal year end using the prescribed CRA form set (i.e. “T661”). This form requires substantial technical and financial information. It must be correctly prepared in order to avoid the claim being rejected by CRA as incomplete. Furthermore, CRA may not accept additional information on claims that are ruled incomplete after the filing deadline even if the original claim was filed on time.
- CRA regularly audits both scientific, technical and financial aspects of SR&ED claims. Every CRA taxation services office has a team of engineers and scientists who perform reviews and site audits of SR&ED claims.
Processing of SR&ED Claims by the CRA
Gate #1 – Filing is complete?
- All information / data provided?
- Correct / current version of form T661 used?
- Written description of claimed R&D that was undertaken in this taxation year (i.e. the “systematic investigation”)?
- Written justification that R&D work being claimed involved seeking a “scientific or technological advancement” and what specific “technological obstacle / uncertainty” obstructed that advancement?
- Wages and other expenditures identified for each project in the claim?
- Details of incoming and outgoing contract payments for R&D services?
- Names and qualifications of key personnel involved in each project?
Gate #2 – Received on time?
- < 6 months from year end = fast track processing (120 to 240 days)
- 6 to 18 months from year end = slower processing (8 to 16 months)
- > 18 months from year end = rejected and forever lost
Gate #3 – Technical audit
- Claimed activities meet CRA definition of eligible R&D activity?
- Scientific and technical records and / or working papers corroborate work done in claimed period?
Gate #4 – Financial audit
- Taxpayer entitled to claim as CCPC / ECPC and qualifies for high-rate refundable benefit?
- Invoices and pay records to support claimed costs?
- Time records to support allocation of man-hours to specific projects?
- Any incoming contract payments to reduce the benefit?
Gate #5 – Dispute resolution (in the event of disagreement with technical or financial audit outcome)
- Second opinion by audit supervisor at local CRA office.
- Notice of Objection – triggers a second audit by a separate independent group of auditors within CRA.
- Tax Court of Canada – taxpayer contests CRA ruling in a formal court process that is completely independent of CRA influence.
Criteria for Eligible R&D Activity
All of the following three criteria must be met for an R&D activity to qualify as eligible SR&ED:
- A technological or scientific Advancement is sought
- New to world (generally eligible)
- New application (probably eligible)
- New to company (may be eligible)
- Technological Uncertainty / Obstacle obstructs the advancement
- An initial attempt to apply the “standard practice” failed
- Competent professionals with appropriate training and credentials could not devise a solution from within their “oeuvre” of professional knowledge
- Insufficient information or data is available to enable application of standard engineering practices
- Potentially useful solutions exist but are unavailable in the public domain
- Key properties of materials are unknown
- Vital relationships are unknown or unproven
- Interactions of components in a complex system cannot be reliably modeled or predicted
- Systematic Investigation – an iterative process of experimentation is employed in an attempt to resolve the uncertainty and achieve the advancement
- Theory or idea conceived
- Experiments conducted to test idea
- Measurements are made and recorded
- Results are compared to a “control” group or standard
- Idea evolved based on findings in an iterative process
- Investigation process continues until technological uncertainty is resolved at which point the SR&ED eligible work ends
The outcome of the R&D activity (i.e. success or failure) is not a criterion for eligibility.
What R&D Expenditures Are Covered?
- Current expenditures
- Wages & salaries of scientific / technical personnel directly engaged in R&D
- Materials consumed in R&D, i.e. net of recoveries from sale
- 80% of contract payments to persons or individuals you engage to provide R&D services
- Capital expenditures
- Expenditures for capital equipment used for R&D purposes (e.g. measuring instruments, scientific / engineering software) acquired (or leased) on or after December 16th 2024.
- Overhead – two options
- Proxy Method: Calculated as a % of wages and salaries. 55% after 1-Jan-2014
- Traditional Method: Actual as required and incurred in relation to the claimed R&D work
- Excluded
- Purchases of intellectual property (e.g. patents)
- Training
- Work done outside Canada: Only R&D work carried out in Canada is eligible for SR&ED. However, recent amendments to legislation make allowance for up to 10% of the wage expenditures to be for work outside Canada, but only if that work is directly associated with (and vital) to an SR&ED project undertaken by the taxpayer in Canada.
- Legal fees, accounting fees, patent fees etc.
- Certain payments or assistance received in respect of the claimed activity may act to reduce the eligible expenditures
- Government grants – NSERC, CIRDF, IRAP, SDTC etc.
- Government loans (FedDev, ACOA etc.)
- Payments received from customers for R&D services or sale of R&D results. NB: There are certain cases when such payments would not act to reduce SR&ED benefits. However, this is a complex matter which is beyond the scope of this document.
Tax Credit Financial Terminology
- Normal business deduction – Expenditures on R&D act to reduce taxable income exactly like any other business expense.
$100 spent on R&D, reduces taxable income by $100 - Super-deduction – R&D expenditure produces higher than normal deduction.
$100 spent on R&D, reduces taxable income by $200 - Immediate or accelerated write-off – Faster depreciation of capital assets such as R&D equipment or purchased IP.
$100 spent on depreciable R&D equipment or IP reduces taxable income by $100 in first year instead of $33 per year for three years - Investment tax credit – Direct reduction of taxes payable by all or some % of the R&D expenditure.
At ITC rate of 15%, an R&D expenditure of $100 reduces payable tax of $1,000 down to $985 - Refundable cash benefit – Benefit paid in cash, even if no taxable income.
At ITC rate of 35%, an R&D expenditure of $100 reduces tax payable of $10 to $0 and generates a refund cheque of $25
Simple Overview of SR&ED Benefit Rates (for Ontario)
1. For a Canadian Controlled Private Corporation (CCPC) or an Eligible Canadian Owned Public Corporation (ECPC)
- Federal benefit of up to 35% of R&D expenditures as a cash refund. This 35% rate is diminished and becomes only partially refundable on expenditures in excess of the expenditure limit which is currently $6M. However, this $6M limit is ground down if the corporation’s prior year taxable capital (for CCPCs) or its average gross revenue over prior three years exceeds $15M (for ECPCs and CCPCs). This grind down occurs on a straight-line basis such that at $75M the 35% is reduced to 15%, which is 40% refundable for CCPCs and 0% refundable for ECPCs.
- Ontario Innovation Tax Credit benefit of up to 8% on R&D expenditures up to the provincial expenditure limit (presently $3M) as a cash refund. However, the $3M provincial expenditure limit is ground down if either the corporation’s prior year taxable income exceeds $500,000 or its prior year taxable capital exceeds $25M. This grind down occurs on a straight-line basis such that at either $800,000 (PYTI) or $50M (PYTC) the entitlement to OITC is entirely eliminated.
- Ontario Research and Development Tax Credit of 3.5% to offset the inclusion of the Federal SR&ED benefit into Ontario taxable income as a result of harmonization.
2. For Non-CCPC Corporations
- Federal benefit of 15% of R&D expenditures as an investment tax credit (ITC) but no cash refund. ITC may be either applied to reduce taxable income in the current tax year or carried forward 20 years or backward 3 years.
- Ontario Innovation Tax Credit benefit of up to 8% on R&D expenditures up to the provincial expenditure limit (presently $3M) as a cash refund. However, the $3M provincial expenditure limit is ground down if either the corporation’s prior year taxable income exceeds $500,000 or its prior year taxable capital exceeds $25M. This grind down occurs on a straight-line basis such that at either $800,000 (PYTI) or $50M (PYTC) the entitlement to OITC is entirely eliminated.
- Ontario Research and Development Tax Credit of 3.5% to offset the inclusion of the Federal SR&ED benefit into Ontario taxable income as a result of harmonization.
3. For Other Corporations (i.e. unincorporated businesses, individuals and partnerships)
- Federal benefit of up to 15% of R&D expenditures, 40% of which is as a cash refund with balance as an investment tax credit (ITC).
- No Ontario benefits.
Notes:
- Above apply to organizations with permanent establishments in Ontario. Most other provinces also have their own specific R&D benefits ranging from 10% to 40%.
- Assumes all R&D work done at a permanent establishment in Ontario.
