How To Prepare for A CRA Audit?

Updated: Oct 28, 2023

Preparing for a Canada Revenue Agency (CRA) audit can help make the process smoother and less stressful. Here are the steps you should consider taking to prepare for a CRA audit.

Understand the Audit Letter:

Carefully read the audit letter you receive from the CRA. It will specify the type of audit, the period under review, and the specific areas or issues they are examining.

Engage a Tax Professional (Optional):

Consider hiring a tax professional, such as an accountant or tax lawyer, to assist you throughout the audit process. They can provide guidance, review your records, and communicate with the CRA on your behalf.

Gather Documentation:

Collect and organize all relevant financial records, receipts, invoices, and supporting documentation for the tax years under audit. Ensure that you have records for all income, expenses, deductions, and credits.

Review Tax Returns:

Review your tax returns for the audit period to ensure accuracy and completeness. Make any necessary corrections or amendments before the audit begins.

Organize Your Records:

Systematically organize your financial records. Create separate folders or files for different categories of documents, making it easier to provide the CRA with the requested information.

Meet with Your Tax Professional (if applicable):

If you have engaged a tax professional, meet with them to discuss the audit, provide the necessary documentation, and develop a strategy for addressing potential issues.

Communicate with the CRA:

Contact the CRA auditor assigned to your case to discuss the audit process and ask any questions you may have. Maintain open and respectful communication throughout the audit.

Prepare for Interviews (if necessary):

If the CRA plans to conduct interviews with you or your representatives, prepare for these meetings by reviewing your records and being ready to answer questions about your finances.

Be Timely and Cooperative:

Respond promptly to any requests or inquiries from the CRA auditor. Cooperation is essential in ensuring a smooth audit process.

Seek Clarification if Needed:

If you are unclear about any aspect of the audit or the CRA's requests, do not hesitate to seek clarification. It's essential to have a clear understanding of what is expected.

Review and Confirm the Audit Findings:

After the audit is complete, carefully review the auditor's findings. If you agree with the results, follow any instructions for payment or adjustments. If you disagree, discuss your concerns with the auditor.

Consider Appeals (if necessary):

If you disagree with the audit findings, you have the right to appeal. Consult with a tax professional to understand the appeal process and the necessary steps to take.

Maintain Documentation:

Even after the audit is concluded, retain copies of all audit-related documents, correspondence, and records for the required retention period (usually six years). This will be useful in case of future audits or disputes.

Review and Improve Tax Compliance:

Use the audit experience as an opportunity to review your tax compliance procedures and make improvements to avoid issues in the future.


Remember that a CRA audit is a standard procedure, and it's essential to approach it with transparency, cooperation, and thorough preparation. Seeking professional assistance can be particularly beneficial if your tax situation is complex or if you have concerns about the audit process.
