SR&ED Audit: What to Expect and How to Prepare

Opening Answer

If your SR&ED claim is selected for review, it does not mean something is wrong. It does mean the CRA wants to validate your work and your numbers.

A well-prepared company can move through an audit with minimal disruption and still recover 15% to 35% of eligible costs. A poorly prepared one can see claims reduced by $20,000 to $100,000 or more, even when the work was valid.

For example, a company claiming $280,000 in eligible expenditures could lose $50,000 or more simply because its technical documentation did not clearly explain the uncertainty or its financials did not align with the work.

The audit process is structured and predictable once you understand how the Canada Revenue Agency (CRA) evaluates claims.

Why Audits Happen

Not all SR&ED claims are audited, but many are.

Common Triggers

• First-time claimants
• Large or unusually high claims
• Vague or generic technical descriptions
• Inconsistencies between costs and work
• Industry-specific risk patterns

Important Clarification

An audit is not an accusation of wrongdoing. It is a validation process to confirm that your work meets SR&ED criteria and that your expenditures are accurate.

Reality from Experience

From our work across industries, many audited claims are valid but poorly presented. Most issues arise from documentation gaps, not ineligibility.

Audit Process

Understanding the process removes most of the anxiety.

Step 1: Initial Contact

The CRA notifies you that your claim is under review, may request documents up front, and assigns technical and financial reviewers.

Step 2: Information Request

You may be asked to provide:

• Technical explanations
• Supporting documentation
• Financial breakdowns

Step 3: Technical Review

A CRA technical reviewer evaluates:

• Whether there was technological uncertainty
• Whether there was systematic experimentation
• Whether there was advancement

Step 4: Financial Review

A financial reviewer checks:

• Salaries and allocations
• Contractor eligibility
• Expense accuracy

Step 5: Meetings or Interviews

In some cases, the CRA may speak with your engineers or technical staff and ask about the work performed.

Step 6: Outcome

The claim may be accepted in full, accepted in part with adjustments, or in rare cases denied.

Timeline

Reviews typically take 2 to 6 months, depending on complexity.

How to Prepare

Preparation is the difference between a smooth review and a painful one.

1. Strengthen Documentation

You need clear evidence of:

• Technical uncertainty
• Testing and iteration
• Learning outcomes

Start with your SR&ED documentation guide.

2. Align Technical and Financial Data

Every cost should connect to:

• A person
• A project
• A qualifying activity

3. Prepare Your Team

Technical staff should be able to explain:

• What problem they were solving
• Why it was difficult
• What they tried

4. Avoid Over-Explaining or Guessing

During review:

• Stick to facts
• Do not speculate
• Do not reframe work inaccurately

5. Review Before Submission

Many audit issues originate from weak initial claims and poorly structured narratives.

What CRA Is Really Looking For

This is where most businesses misunderstand audits.

The CRA is not asking whether you built something valuable. They are asking:

• What was unknown?
• Why could standard methods not solve it?
• What did you actually test?
• What did you learn?

Key Insight

A technically strong project with weak documentation often performs worse than a moderate project with strong documentation.

Expert Support

Not every audit requires external help, but many benefit from it.

When to Get Support

• First-time audit
• Large claim amounts
• Weak documentation
• Unclear technical narratives
• Previous claim adjustments

What Expert Support Does

• Clarifies technical positioning
• Aligns documentation with CRA expectations
• Prepares your team for questions
• Reduces risk of claim reduction

Real Impact

We regularly help companies recover claims initially reduced by the CRA, defend eligibility under review, and improve outcomes without inflating claims.

The Biggest Audit Mistake

Treating the audit as a defense exercise instead of a clarification exercise. You are not trying to win an argument. You are helping the CRA understand what you did, why it qualifies, and how your costs relate to that work.

FAQ

What is an SR&ED audit?
A review by the CRA to verify that your claim meets eligibility criteria and that your costs are accurate.

How long does an SR&ED audit take?
Typically 2 to 6 months, depending on complexity.

Do all claims get audited?
No, but first-time and larger claims are more likely to be reviewed.

Can my claim be reduced?
Yes, especially if documentation or cost allocation is weak.

How do I prepare for an SR&ED audit?
Ensure strong documentation, align financials with technical work, and prepare your team to explain the work clearly.

Next Step

Most SR&ED audits do not fail because the work is not eligible. They fail because the story is not clear.

We regularly help businesses:

• Defend claims under review
• Strengthen technical narratives
• Recover value from reduced claims

If your claim is under review, or you want to avoid issues before filing, structured audit preparation can make all the difference.
