Read the complete letter
A CRA review may ask for documents supporting a deduction or credit. A reassessment changes a previously assessed return. These are not interchangeable processes, and neither should be ignored. Note the tax year, account, reference number, issue and stated deadline.
Respond to what was actually requested
Collect the relevant receipts, forms and calculation details. A focused response is more useful than an unorganized collection of unrelated documents. Keep copies of what you submit and evidence of submission. If you cannot meet a response date, contact the appropriate CRA office promptly rather than assuming an extension.
Compare a reassessment with the original filing
Identify the amounts changed and the explanation given. Sometimes the issue is missing support; other times it involves an interpretation of the rules. An adjustment request and a formal objection serve different purposes. The appropriate response depends on the issue and the available process.
Protect deadline-sensitive options
Objection deadlines vary by taxpayer and circumstance. Do not assume the review letter’s response date is the same as an objection deadline. Seek qualified assistance promptly, and obtain specialist legal advice where needed. No adviser can guarantee the CRA will reverse a decision.
Frequently asked question
Should I ignore a review if I believe my return was correct?
No. A correct claim may still need documentation. Read and respond to the request within the applicable process and deadline.
