MONTREAL CPA FIRM NEAR YOU: HOW TO RESPOND TO A CRA REQUEST FOR INCOME VERIFICATION

Understanding Income Verification Requests
CRA issues income verification requests when amounts reported on your tax return do not match information provided by employers, banks, investment firms, pension providers, or government agencies. Montreal CPAs help clients interpret these requests, identify discrepancies, and prepare accurate responses to avoid reassessments or penalties.
Why CRA Asks for Income Verification
Income discrepancies can arise for several reasons:
Missing or late slips (T4, T5, T4A, RL-1, RL-3)
Incorrect amounts reported by third parties
Unreported employment income
Rental or business income mismatches
Capital gains reporting inconsistencies
Montreal CPAs analyze the triggers behind the request to determine whether it is routine or indicative of a larger issue.
Identifying the Slips or Income Sources Under Review
CRA letters specify which income items require verification. Montreal CPAs help clients:
Match requested items to original filings
Confirm whether slips were included
Retrieve missing documents
Identify misreported or duplicated amounts
Understanding precisely what is being questioned prevents unnecessary back-and-forth with CRA.
Gathering the Correct Supporting Documents
Income verification requires accurate and official documentation. Montreal CPAs assist in assembling:
T5 investment income slips
T4A pension or commission slips
RL-series slips from Revenu Québec
Bank statements for interest income
Brokerage statements for capital gains
Providing complete and organized support reduces the risk of reassessment.
Correcting Missing or Incorrect Slips
Sometimes third parties issue incorrect or amended slips. Montreal CPAs help clients:
Request corrected slips
Contact employers or financial institutions
Obtain missing RL slips from Revenue Québec
Corrected documentation strengthens the accuracy of the response.
Drafting a Professional Explanation
A clear, concise explanation is essential when responding to CRA. Montreal CPAs prepare letters that:
Address each discrepancy
Provide context where needed
Reference enclosed supporting documents
Align explanations with tax legislation
This level of clarity demonstrates credibility and reduces the likelihood of further review.
Understanding Consequences of Unverified Income
If income is not verified properly, CRA may:
Add unreported income
Charge penalties for omission or negligence
Apply daily compound interest
Initiate broader audits
Montreal CPAs help clients avoid these consequences by preparing strong, compliant responses.
Handling Employment Income Discrepancies
Discrepancies in T4 amounts are common. Montreal CPAs:
Reconcile gross income to pay records
Confirm taxable benefits
Identify employer reporting errors
Proper reconciliation helps prevent inaccurate reassessments.
Responding to Investment Income Queries
CRA often reviews interest, dividends, and capital gains. Montreal CPAs verify:
Accrued vs. received interest
Dividend gross-up and credit calculations
Capital gains and adjusted cost base (ACB) accuracy
Foreign income declarations
Detailed review avoids incorrect tax increases.
Addressing Business or Rental Income Differences
CRA may question self-employment or rental income when:
Bank deposits exceed reported income
Expenses appear inconsistent
E-commerce transactions lack matching invoices
Montreal CPAs help clients prepare reconciliations and supporting schedules to satisfy CRA verification requirements.
Submitting Income Verification Within Deadlines
CRA deadlines are strict and can be as short as 15 days. Montreal CPAs ensure:
Responses are timely
Documentation is complete
No deadlines are missed
Timely action avoids penalties and prevents CRA from making arbitrary adjustments.
What to Do if CRA Disagrees With Your Explanation
If CRA rejects documentation, they issue a reassessment. Montreal CPAs:
Explain the rationale for the reassessment
Prepare additional support
Initiate a formal Notice of Objection if warranted
Strong objection strategies help protect your rights and reverse incorrect decisions.
Preventing Future Income Verification Requests
Montreal CPAs help clients adopt proactive measures such as:
Reconciling all slips before filing
Verifying employer and bank reporting
Maintaining organized digital records
Filing consistent financial information across platforms
Better preparation reduces future CRA scrutiny.
Using CRA and ARQ Digital Portals
Income slips and tax documents often appear on:
CRA My Account
CRA My Business Account
Revenu Québec ClicSÉQUR
Montreal CPAs help clients navigate these tools to retrieve official documents quickly and ensure accuracy before submitting returns.
Maintaining Full Compliance Throughout the Review
During income verification, taxpayers must continue meeting other obligations such as instalments, GST/QST filings, payroll remittances, and corporate returns. Montreal CPAs ensure ongoing compliance to avoid additional problems during the review process.
