What Ontario Business Owners Should Do When CRA Sends a Review Letter

Opening your mail and finding a letter from the Canada Revenue Agency (CRA) can be stressful.

Many business owners immediately assume they are being audited. In reality, a CRA review letter is often a request for supporting documentation or clarification regarding information already submitted. Receiving a review letter does not automatically mean something is wrong.

The key is responding promptly, accurately, and with proper documentation.

What Is a CRA Review?

A CRA review is generally a verification process where the agency requests information to support claims, deductions, credits, or reported income previously submitted on a tax return.

The purpose is to ensure that the information reported is accurate and supported by records.

Businesses should maintain organized books and records throughout the year to make it easier to respond if information is requested.

Step 1: Read the Letter Carefully

Before gathering documents, read the entire letter.

Pay attention to:

• The tax year being reviewed

• The information being requested

• The submission deadline

• Instructions on how to respond

Missing the response deadline can create additional delays and complications.

Step 2: Don't Panic

Many review letters are resolved quickly when supporting documents are supplied.

Business owners often make mistakes because they react emotionally and send incomplete information.

A better approach is to:

• Review the request carefully

• Gather all supporting documents

• Verify the information before submission

Step 3: Organize Your Documentation

Depending on the request, CRA may ask for:

• Receipts

• Invoices

• Bank statements

• Payroll records

• GST/HST documentation

• Proof of business expenses

Good bookkeeping is your first line of defence.

If records are organized monthly, responding becomes significantly easier.

Step 4: Review Your Records Before Responding

Compare the requested information with:

• Your bookkeeping records

• Filed tax returns

• Corporate records

• Bank reconciliations

Sometimes a review highlights discrepancies that can be explained easily with supporting documentation.

Step 5: Respond Before the Deadline

The CRA provides instructions on how documents should be submitted.

Responding on time demonstrates cooperation and helps prevent unnecessary follow-up requests.

Keep copies of:

• The original letter

• All documents submitted

• Confirmation of delivery

Common Mistakes Business Owners Make

• Waiting Until the Deadline

Leaving everything until the last week creates unnecessary stress and increases the likelihood of missing information.

• Sending Incomplete Documentation

Providing partial information may result in additional requests.

• Ignoring the Letter

Ignoring CRA correspondence rarely makes a situation disappear and can create larger issues later.

• Poor Record Keeping

Businesses with disorganized bookkeeping often spend hours searching for information that should be easily accessible.

How to Prepare Before CRA Ever Contacts You

The best strategy is prevention.

Maintain:

✅ Monthly bookkeeping

✅ Digital copies of receipts

✅ Regular bank reconciliations

✅ Organized GST/HST records

✅ Payroll documentation

✅ Year-round financial reports

Being prepared reduces stress and allows you to respond confidently if questions arise.
