SR&ED Eligible Activities: What Qualifies? (2024)

Understanding which activities qualify for SR&ED (Scientific Research and Experimental Development) tax credits is crucial for maximizing your claim. This guide explains eligibility criteria with concrete examples across industries.

The SR&ED Definition

SR&ED includes systematic investigation or search through experimentation or analysis to achieve:

Experimental development - Creating new or improving existing materials, devices, products, or processes
Applied research - Advancing scientific or technological knowledge for specific application
Basic research - Advancing scientific knowledge without specific application (rare in business)

Plus supporting work directly undertaken to support the above.

The 5-Question Eligibility Test

For each project or activity, ask these questions:

1. Was there scientific or technological uncertainty?

What this means:

Outcome wasn't known or achievable at the outset
Standard practice couldn't solve the problem
Required experimentation to resolve

YES examples:

"We didn't know if our algorithm could process real-time data fast enough"
"No existing method achieved the required purity level"
"Standard manufacturing couldn't achieve the tolerance required"

NO examples:

"We followed standard implementation procedures"
"The technology was proven; we just had to apply it"
"It was difficult but not uncertain"

2. Did you formulate hypotheses?

What this means:

Proposed potential solutions before testing
Made educated guesses about approaches
Had theories to validate or invalidate

Examples of hypotheses:

"We believed a neural network approach would outperform traditional algorithms"
"We hypothesized that reducing temperature would improve yield"
"We theorized the new architecture would handle 10x throughput"

3. Was there systematic experimentation or analysis?

What this means:

Structured testing approach
Controlled variables
Analysis of results
Iteration based on findings

YES examples:

"Tested 8 different configurations measuring performance metrics"
"Conducted series of trials with varied parameters"
"Analyzed failure modes and adjusted design"

NO examples:

"Trial and error without structured approach"
"Just tried different things until it worked"
"No documentation of tests or results"

4. Was it conducted by qualified personnel?

What this means:

Engineers, scientists, developers, technologists
Or technicians working under their supervision
Relevant technical expertise

5. Did you achieve technological advancement?

What this means:

Gained new knowledge or capability
Advanced beyond previous state
Resolved the uncertainty

Advancement examples:

"Achieved 40% faster processing than existing methods"
"Developed new manufacturing process that improved yield by 25%"
"Created novel algorithm that solved previously intractable problem"

Gray Areas and Judgment Calls

Improvement vs. Innovation

KEY QUESTION: Is this routine improvement or genuine technological advancement?

Eligible (Improvement with Uncertainty):

Trying to achieve something beyond current capability
Outcome was unknown before experimentation
Required systematic investigation

Not Eligible (Routine Improvement):

Incremental enhancement using known methods
Predictable outcome based on standard practice
No technical uncertainty involved

Difficulty vs. Uncertainty

KEY DISTINCTION: Difficult doesn't mean SR&ED

Eligible (Uncertainty):

"We didn't know IF we could achieve the requirement"
Solution wasn't known at the outset
Experimentation was necessary to find solution

Not Eligible (Just Difficult):

"We knew HOW to do it but it was hard"
Solution was known; execution was challenging
Time, cost, or resource constraints (not technical)

Supporting Work

Eligible supporting work: Must be directly undertaken to support SR&ED and cannot be otherwise acquired.

Examples:

Programming specifically for SR&ED experiments

Data collection for analysis of SR&ED results
Testing of SR&ED prototypes

Not eligible:

General skills development
Overhead activities
Work that could support SR&ED and commercial production equally

Common Questions About Eligibility

Can failed projects qualify?

YES! Failed projects are often excellent SR&ED. You tested hypotheses, conducted experiments, and learned something—even if the result was "that approach doesn't work."

Example: "Tested 5 approaches to improve battery life. All failed to meet targets, but we determined fundamental limitations and identified promising alternative approach for next year."

Does work need to succeed to qualify?

No. SR&ED is about the process of experimentation, not the outcome. The question is whether you faced uncertainty and investigated systematically—not whether you succeeded.

Can routine work become SR&ED?

Sometimes. If routine work encounters unexpected technical problems requiring systematic investigation to resolve, that investigation may qualify.

Example: Production process suddenly fails. Root cause analysis reveals unknown technical issue. Systematic experimentation to solve becomes SR&ED.

Does work need to be new to the world?

No. SR&ED requires advancement of your company's knowledge—not necessarily new to the world. However, the uncertainty must be genuine (not solvable through standard research).

Can I claim the same type of project every year?

Yes, if uncertainty continues. Many companies have ongoing R&D in similar areas. Each year's work must face genuine uncertainty and involve systematic investigation.

Building Your Eligibility Case

Documentation Approach

For each potential SR&ED project:

Describe the objective - What were you trying to achieve?
Explain the uncertainty - What didn't you know? Why couldn't standard practice solve it?
Document the hypotheses - What approaches did you propose?
Record experiments - What tests did you conduct?
Show results and analysis - What did you find? How did you iterate?
Describe advancement - What new knowledge or capability was achieved?

Language Tips

Use this: "technological uncertainty," "hypothesized," "experimented," "analyzed," "advancement"

Avoid this: "developed," "implemented," "fixed," "improved" (without technical context)

Good: "We faced technological uncertainty regarding..." Bad: "We developed a new feature..."

Frequently Asked Questions

How much of my project can I claim?

Only the portion involving SR&ED. If a project is 60% SR&ED and 40% routine implementation, claim 60%.

Do I need patents to claim SR&ED?

No. SR&ED and patents are separate. Eligible SR&ED often doesn't result in patents.

Can I claim work done by interns?

Yes, if they're paid and performing SR&ED work (or supporting work under qualified supervision).

What about work that becomes a product?

The R&D portion qualifies; commercial production doesn't. Claim the experimentation phase, not the production phase.

Can subcontracted work qualify?

Yes, 80% of arm's-length contractor payments for SR&ED work are eligible.
