CRA Audit & Reassessment: A Controlled First-Response Framework
A first-response framework for CRA audits and reassessment issues built around scope, records and assessment documents.
Information reviewed against referenced sources:
What should be organised after a CRA audit or reassessment issue arises?
Identify the tax period, communication or assessment, the issue being reviewed, the response or objection deadline and the records supporting the filed position before taking substantive action.
Anchor the response to the CRA issue and evidence
Reconstruct the filed position and the relevant evidence before deciding whether the matter is clarification, correction, objection or a broader audit response.
Map the CRA communication to the filed position and supporting records
Start with the CRA letter, notice of assessment/reassessment or audit request. Identify the period, issue, amounts under review and requested information. Then reconstruct the relevant part of the filed return from records before deciding whether the next step is document submission, clarification, adjustment, objection or another formal response.
Keep a response log for submissions, deadlines and CRA follow-up
A controlled response file should record the request date, deadline, documents supplied, delivery evidence and later CRA communications. This becomes particularly important when a review develops into a reassessment or objection because the factual history remains visible to the taxpayer and representative.
