CRA letters, decoded

Your personal return is under review. Owner-managers: read this first.

Reviewed by EverStone CPA · August 2026

Quick answer: A T1 review letter asks for documents behind specific claims on your personal return — and owner-managers see them more than employees do, because the claims that get reviewed most are the ones business owners make: vehicle and home-office expenses, dividends and salary reconciling to the corporation’s slips, and moving money between you and the company. The letter names the lines; the response is the paperwork behind exactly those lines.

Why owner-managers get more of these

An employee’s return is mostly slips the CRA already holds, so there is little to review. An owner’s return carries judgement: business use of a vehicle, home-office claims, and amounts that have to agree with what the corporation filed. Each of those is a named review category, and none of them is a problem when the records exist.

The support each common claim needs

  • Vehicle: the contemporaneous log — kilometres, dates, purpose. Our free log exists because this is the request that catches people without one.
  • Home office: the workspace calculation and the bills behind it — and for incorporated owners, consistency with how the corporation treated the same costs.
  • Dividends and salary: the T5 and T4 the corporation issued. Where the corporation’s filings and your return disagree, fix the source, not the symptom — the shareholder loan record is usually where the answer lives.

Respond precisely, on time, in writing

Quote the reference number, answer the named lines completely, send nothing beyond them, and respond through the channel the letter states before its stated date. If a claim turns out to be unsupportable, conceding it in the response costs less than defending it into a reassessment — and if you disagree with the outcome, the objection route exists and has its own clock.

Common questions

Why was my return picked if nothing changed?+
Review selection mixes random sampling with category screening, so a return identical to last year’s can still be picked. A letter is not an allegation — it is a request to show support for claims in categories the CRA verifies routinely.
What if the records are with my old accountant?+
You are entitled to your own records — ask for them, and start assembling what you hold in parallel. If the deadline is at risk, request the extension before it passes rather than going silent.
Can this turn into a corporate review?+
The T1 and T2 sides can inform each other where amounts have to reconcile — which is a reason to make sure they do reconcile before responding, and a good moment to have one professional see both sides.
