Category: Tax Reading time: 10 min read Published: 1/3/2026

What happens in a CRA audit? Learn from real scenarios: unreported income, expense claims gone wrong, and how businesses survived (or didn't).

๐ŸŽฏ Key Takeaways
  • CRA audits follow patterns - know the triggers
  • Documentation is your best defense
  • Unreported cash income is the biggest risk
  • Personal expense claims through business are easily caught
  • Cooperation generally leads to better outcomes

๐Ÿ” Understanding CRA Audits

Getting a letter from CRA is stressful. Understanding what happens - and learning from others' experiences - can help you prepare and prevent issues.

Note: These scenarios are composites based on common audit situations. No client information is disclosed.

๐Ÿ“– Case 1: The Cash Business Problem

๐Ÿฝ๏ธ
The Situation

A restaurant owner reported $300,000 in annual sales. CRA compared to similar restaurants and found:

  • Similar-sized restaurants averaged $500,000+ in sales
  • Food purchases suggested higher volume
  • Employee hours didn't match reported revenue
๐Ÿ“Š
What CRA Did
  • Requested bank statements (all accounts)
  • Analyzed food cost ratios
  • Calculated expected sales from purchases
  • Conducted "net worth" analysis of owner
The Outcome

CRA assessed $150,000 in additional income over 3 years. With penalties and interest, total owing: $80,000+

Lesson: Report ALL income. CRA has industry benchmarks and will spot anomalies. Your purchases tell the story your sales should confirm.

๐Ÿ“– Case 2: The Vehicle Expense Overreach

๐Ÿš—
The Situation

A sales consultant claimed 95% business use on their vehicle. CRA asked for a logbook.

๐Ÿ“‹
The Problem
  • No logbook existed
  • Calendar showed many days without client meetings
  • GPS records from oil changes showed mostly local driving
  • Social media showed weekend trips and personal activities
The Outcome

CRA allowed only 40% business use. Reassessed 3 years of returns. Additional tax: $12,000

Lesson: Keep a contemporaneous logbook. CRA accepts 90-day sample periods. Claiming 90%+ business use without documentation is a red flag.

๐Ÿ“– Case 3: The Home Office Adjustment

๐Ÿ 
The Situation

A consultant claimed 50% of home expenses for home office. CRA audited.

๐Ÿ”
What CRA Found
  • Home was 2,000 sq ft
  • "Office" was 150 sq ft bedroom (7.5%)
  • Also used as guest room
  • 50% claim was unsupportable
The Outcome

CRA allowed 5% (reflecting shared use). Reassessed 2 years. Additional tax: $4,500

Lesson: Home office claims must be proportionate to actual use. Measure your space. If it's also a guest room, reduce the claim accordingly.

โœ… How to Protect Yourself

  • Report all income (including cash)
  • Keep receipts for all expenses
  • Maintain a vehicle logbook
  • Measure and document home office space
  • Separate personal and business expenses
  • Don't claim personal meals as business
  • Keep records for 6 years
  • If in doubt, ask before claiming
