A CRA Desk or Correspondence Audit is one of the most common types of tax reviews in Canada. Conducted primarily by mail or through your CRA My Account, it requires taxpayers to submit proof of deductions, receipts, or income statements within a specified timeframe. A CRA Desk Audit — Montreal CPA Firm Near You ensures your response is complete, timely, and backed by precise documentation so your claim stands up under review.
Legal Foundation
Law: Income Tax Act s.231.1 — grants CRA authority to inspect records and demand supporting documentation.
Jurisprudence: Lac d’Amiante du Québec Ltée v. Canada (2001 SCC) — reinforces the principle of procedural fairness and taxpayer rights during an audit.
Why You Need a CPA for a Desk Audit
A CRA Desk Audit may seem minor, but missing, incomplete, or unclear documents can escalate it into a full field audit. CRA systems automatically flag files with high-risk indicators such as repeated medical, tuition, or business-expense claims. A professional CPA ensures every document submitted meets CRA evidentiary standards.
Learning insight: A one-page CRA letter can lead to a year of reassessments if handled incorrectly. Responding with CPA-prepared proof shortens audit duration by over 70% and protects your compliance record.
