How CRA Selects Files for Audit
CRA selects files for audit through risk assessment, random selection, and industry-targeted campaigns. Risk assessment evaluates factors like large expense-to-income ratios, prior filing history, and industry norms. As a former tax auditor, Ahmed knows the selection criteria and can assess your audit risk, and reduce it through proper filing.
- Risk assessment: CRA scores returns based on expense ratios, deductions, and filing patterns.
- Random selection: Some files are selected randomly. No specific trigger.
- Industry campaigns: CRA targets specific industries based on compliance data.
- Third-party tips: Information from informants or matching discrepancies can trigger selection.
Types of CRA Audits
CRA conducts several types of audits, each with different scope and procedures. The type of audit affects what records you need to produce and how long the process takes. Ahmed handles all audit types with insider knowledge of how each works from the inside.
| Type | Where | Scope |
|---|---|---|
| Correspondence review | Mail-in | Specific documents requested. Simplest type |
| Desk audit | CRA office | Detailed examination of records at CRA office |
| Field audit | Your business | Comprehensive on-site examination |
| Payroll audit | CRA office or on-site | CPP, EI, income tax deductions review |
| GST/HST audit | CRA office or on-site | GST collection, ITCs, and filing review |
What to Expect at Each Stage
The audit process follows stages: initial contact and scope letter, document request, examination, findings discussion, proposal letter, and final assessment. Each stage has specific expectations and deadlines. Ahmed manages the entire process, controlling what information is shared and when.
- Initial contact: CRA sends a letter outlining the audit scope and requesting an initial meeting.
- Document request: CRA provides a list of records needed: receipts, bank statements, ledgers.
- Examination: The auditor reviews documents and may ask follow-up questions.
- Findings discussion: Auditor discusses preliminary findings before issuing a proposal.
- Final assessment: If no objections, CRA issues the final reassessment.
Taxpayer Rights During an Audit
You have rights during a CRA audit, including the right to representation, the right to explanations, and the right to appeal. You don't have to answer questions on the spot. You can consult your representative first. Ahmed recommends professional representation for all but the simplest correspondence reviews.
- Right to representation: You can have a CPA or representative handle the audit on your behalf.
- Right to explanations: You can request explanations of audit findings and adjustments.
- Right to appeal: You can file a notice of objection within 90 days of assessment.
- No obligation to self-incriminate: You're not required to provide information beyond what's requested.
The Proposal Letter: A Critical Moment
A proposal letter outlines CRA's intended reassessment before it's issued. You typically have 30 days to respond. This is the most critical moment in the audit. A well-prepared response can prevent the reassessment entirely. Ahmed responds with documentation and legal/factual arguments based on his CRA experience.
- 30-day response window: You have approximately 30 days to respond. Don't waste it.
- Prevent the reassessment: A strong response can stop the reassessment before it's issued.
- Professional response: Never respond to a proposal letter without professional help.
- Documentation: Supporting documents and arguments must be comprehensive and precise.
The Objection Process and Timeline
If a reassessment is issued, you have 90 days to file a notice of objection. CRA reviews the objection and may uphold, vary, or vacate the assessment. If the objection is denied, you can appeal to the Tax Court of Canada. The full timeline from audit selection to final resolution can range from months to years.
- 90-day objection deadline: Strict legislative deadline. No extensions available.
- CRA review: An appeals officer reviews the objection independently of the auditor.
- Tax Court appeal: Available if the objection is denied. 90 days to file.
- Timeline: From selection to resolution can take months to years depending on complexity.
