When the CRA Comes Knocking: Surviving Your SR&ED Audit Unscathed

John Frazer
Manufacturing R&D & SR&ED Consultant

Introduction

An audit notice can feel like a storm warning—but with preparation, it becomes a manageable process. The key: align your narrative, evidence, cost schedule, and responses in advance. This post is your audit survival guide.

Why Audits Happen: Triggers & Red Flags

  • Sudden jump in claimed hours or amounts
  • Weak or vague narrative
  • High ratio of R&D hours vs total engineering
  • Overuse of subcontractors without experiment linkage
  • Thin or retroactive documentation

What CRA Reviews in Depth

  1. Narrative consistency & logic
  2. Time logs / labour allocation
  3. Materials, overhead, subcontractor costs
  4. Experiment records / test logs / failure paths
  5. Contemporaneous evidence
  6. Interviews or site visits

Pre-Audit Readiness Checklist

Task Status Comments
Self-score red flags
Collect logs, emails, change history
Map cost to experiments
Designate contact(s)
Pre-draft responses to likely questions

During the Audit: Best Practices

  • Respond clearly, concisely, and on schedule
  • Always tie claims back to experiments / logs
  • When in doubt, acknowledge weakness but contextualize
  • Don’t volunteer extra materials unnecessarily
  • Keep a log of each CRA request and your response

Handling Adjustments

  • Ask CRA to explain rationale for disallowance
  • Propose a recalibrated claim portion if full disallowance seems likely
  • Provide supplemental evidence or clarification
  • If result is unsatisfactory, consider formal objection / appeal

Real Case Examples (Anonymized)

  • A software firm reclaimed ~300 hours by producing parameter sweep logs after initial pushback
  • A hardware startup defended its CapEx by demonstrating precise usage logs
  • A biotech firm improved future audit outcomes by internal mid-project reviews

Post-Audit: Strengthening Next Year

  • Draft narratives during project (not at year end)
  • Use version control, lab notebooks, test logs from Day 1
  • Run internal mini audits mid-cycle
  • Continually refine your audit scorecard and checklist
