CRA Audit & Review Assistance

Receiving a notice from the Canada Revenue Agency can feel overwhelming — whether it is a routine review or a full CRA audit. At Filing Taxes, we provide specialist CRA audit and review assistance for individuals and businesses in Toronto, Mississauga, and across Canada.

With an increasingly strict regulatory environment, having an experienced accounting team by your side is not just helpful — it is essential to protecting your financial interests.

What is a CRA Tax Audit or Tax Review?

A CRA Tax Review is a request for additional information when the CRA finds discrepancies in your filed return. It may come as a letter, a Notice of Reassessment, or even a phone call asking for supporting documents related to your business or personal account.

A CRA Tax Audit is a deeper, more formal examination of your books and records to confirm you have met all tax obligations. If your response to a review is unsatisfactory, the CRA can audit up to six years back from the date of your Notice of Assessment — or at any time if fraud is suspected. Whether you are an individual or a business, having a personal tax accountant or corporate tax specialist involved from the beginning is critical.

CRA Audit Triggers: What Puts You at Risk?

The CRA selects returns for audit using a risk-based system, targeting taxpayers it believes are at a higher likelihood of non-compliance or tax evasion. They will never disclose exactly why your return was selected, which makes maintaining clean, accurate records at all times essential.

Common CRA audit triggers include:

Your business operates primarily on cash transactions
Business expenses are unusually high compared to your industry
You operate in a higher-risk industry such as retail, construction, food service, or manufacturing
Recurring business losses reported year after year
Overreported home office expenses

The CRA Audit Assessment Process

A CRA audit follows a structured process that begins with a formal notification by phone, mail, or email. The notice will outline the tax years being reviewed, the documents required, and the scope of the audit. You then have the opportunity to submit records for the auditor to review.

After reviewing your documents, the auditor will either confirm your return is correct or issue a proposal letter outlining a proposed reassessment. If issued a reassessment, your options are to pay or file a Notice of Objection. Small business owners and IT consultants are among those who benefit most from having professional representation throughout this process.

Common Mistakes Taxpayers Make During a CRA Audit

The single biggest mistake taxpayers make during a CRA audit is dealing directly with the auditor without professional support. CRA auditors take detailed notes of every statement made — and information can be misrecorded, misinterpreted, or used against you.

Do not face a CRA audit or review alone. Every word said to the auditor matters, and without an experienced accountant representing you, you risk making your situation significantly worse. Learn more about our team and approach before you take another step.

Why You Need Professional CRA Audit Support

During a CRA tax audit, the burden of proof falls entirely on you as the taxpayer. You must demonstrate that every deduction claimed and every income figure reported is accurate and supported by documentation. This is an extremely high-pressure process that most individuals and businesses are not equipped to handle alone.

A professional accountant organizes your records, responds to CRA inquiries accurately, and ensures nothing is said or submitted that could worsen your position. Whether you are dealing with a corporate tax issue or a personal reassessment, the right support makes a measurable difference.
