MONTREAL CPA FIRM NEAR YOU: HOW TO HANDLE A CRA REVIEW OF EXPENSES AND CREDITS

Understanding CRA Pre-Assessment and Post-Assessment Reviews
CRA regularly reviews expenses and credits to verify accuracy. These reviews are not full audits but targeted requests to confirm deductions such as employment expenses, business expenses, donations, medical claims, tuition credits, childcare, rental expenses, or GST/HST/QST input tax credits. Montreal CPAs help clients interpret review letters, understand what triggered the request, and prepare compliant responses.
Why CRA Selects Returns for Review
CRA uses automated matching systems, risk-assessment algorithms, and data from third parties to flag inconsistencies. Reviews may occur when:
Reported expenses exceed norms for your industry or income level
Third-party slips do not match the return
Credits appear unusually high
A previous review identified errors
Montreal CPAs help clients understand the risk factor behind the review to tailor a precise response.
Identifying the Items Under Review
CRA review letters specify exactly which amounts or claims require proof. Montreal CPAs assist clients in identifying:
The specific line items questioned
The supporting documents required
The statutory authority behind the review (Income Tax Act or Excise Tax Act)
Understanding the exact focus ensures accurate preparation and speeds up resolution.
Gathering Strong Supporting Documentation
Successful reviews depend on proper documentation. Montreal CPAs help clients assemble:
Receipts
Invoices
Cancelled cheques
Contracts
Mileage logs
Medical certificates
Donation receipts
Tuition statements
Childcare invoices
Proper organization demonstrates credibility and reduces follow-up requests.
Verifying Eligibility Before Submission
Submitting documents that do not meet CRA standards can result in denial or reassessment. Montreal CPAs verify:
Whether expenses meet statutory criteria
If documentation is valid and complete
Whether amounts align with business or personal use
This step prevents errors that could lead to penalties or future audits.
Drafting a Clear and Professional Response
CRA reviews require concise, factual responses. Montreal CPAs prepare letters that:
Address each item requested
Explain the rationale for the claim
Reference supporting documents in logical order
Demonstrate compliance with the Income Tax Act
A professionally drafted response strengthens your position and minimizes escalation.
Understanding Common CRA Review Areas
Certain expenses and credits trigger reviews more often:
Work-from-home expenses
Travel and vehicle expenses
Medical expenses
Donations
Tuition credits
Moving expenses
GST/QST input credits for self-employed individuals
Montreal CPAs help clients navigate these high-review items with clarity and precision.
Avoiding Common Mistakes During Reviews
Frequent errors that lead to denial include:
Missing receipts
Providing wrong documentation
Submitting personal expenses as business expenses
Failing to provide mileage logs
Inconsistent explanations
Montreal CPAs guide clients to avoid these pitfalls and preserve their deductions.
Responding Within Deadlines
CRA review requests include strict deadlines. Missing them can result in automatic denial of expenses and reassessment. Montreal CPAs manage timelines, prepare submissions quickly, and ensure all documents are delivered on time.
What Happens if CRA Rejects Your Documentation
If CRA disallows expenses or credits, they will issue a Notice of Reassessment. Montreal CPAs help clients:
Understand reasons for denial
Identify missing or weak documentation
Prepare a stronger resubmission
File a formal objection when warranted
This protects your rights and ensures CRA reviews decisions fairly.
Escalating to a Notice of Objection
If a review leads to incorrect tax adjustments, clients may dispute the outcome. Montreal CPAs prepare objections supported by:
Legal references
Financial calculations
Properly organized evidence
Clear arguments based on statutory definitions
Strong objections improve the chances of reversal.
Preventing Future CRA Reviews
Many CRA reviews are avoidable through better tax practices. Montreal CPAs implement preventive measures such as:
Audit-proof recordkeeping
Separating personal and business expenses
Maintaining contemporaneous logs
Keeping digital backups
Filing consistent and accurate returns
Prevention helps reduce scrutiny and stress.
Using Digital Tools to Track Documentation
Digital recordkeeping tools simplify compliance. Montreal CPAs help clients use:
CRA My Account & My Business Account
Revenu Québec ClicSÉQUR
Cloud bookkeeping platforms
Receipt scanning software
These tools reduce errors and speed up CRA review responses.
Maintaining Compliance During the Review Process
Even during a CRA review, ongoing tax obligations continue. Montreal CPAs ensure clients stay compliant with:
GST/QST filings
Source deductions
Instalment payments
Corporate filing deadlines
Proper compliance protects credibility and prevents new issues from arising.
