🎯 Key Takeaways

  • Professional help often pays for itself in savings

Potential Benefits of DIY Filing

  • Save on professional fees
  • Deeper understanding of Canadian tax laws
  • Discover deductions and credits you might not have known about

🤔 Why Most Business Owners Choose Professional Help

Corporate Tax is Complicated

CRA has very specific rules for corporate income tax returns. Without in-depth knowledge, mistakes are easy to make and can be costly.

You Could Pay More Than Necessary

There are many tax credits available to small businesses, but understanding eligibility requirements is complex. Even innocent mistakes can trigger audits.

Variable Filing Deadlines

Unlike personal returns with a fixed April 30 deadline, corporate deadlines vary based on your fiscal year-end. Missing your deadline results in penalties and interest.

⚠️ Audit Risk

Common filing mistakes that trigger audits include:

  • Misclassifying employees as contractors
  • Incorrect home office deductions
  • Unreported income
  • Undocumented mileage claims
