Review assessments, reassessments, CRA documents, risk, and taxpayer position before responding.
Assessment review begins with the document, not with an argument. Before advising a taxpayer, identify what the Canada Revenue Agency issued, which year or period it affects, what amount is disputed, whether the taxpayer still has procedural rights, and what evidence supports the taxpayer’s position.
In CPA Canada Taxation cases, the issue is often not simply “CRA is wrong.” The stronger answer explains what changed, why the taxpayer disagrees, which facts need support, and what next step protects the taxpayer without creating unnecessary cost or disclosure risk.
Assessment review questions usually provide a notice, a CRA letter, an audit adjustment, a reassessment, or a taxpayer complaint. The expected response should classify the document and connect it to rights, evidence, timing, and risk.
| CRA document or fact | Why it matters |
|---|---|
| Notice of assessment | Starts the baseline result after a return is assessed. |
| Notice of reassessment | Shows CRA changed a prior assessed position. |
| Notice of determination or redetermination | May affect losses, credits, benefits, or other amounts. |
| Audit proposal or query letter | Signals review activity but may not itself be an appealable assessment. |
| Request for information | Requires response and evidence, but may not preserve objection rights by itself. |
| Date on the notice | Drives whether a formal objection or appeal deadline is at risk. |
| Amount assessed | Helps decide materiality, cash-flow exposure, and cost-benefit of dispute. |
| Reasons for adjustment | Shows whether the dispute is factual, technical, computational, or procedural. |
Use a disciplined sequence before recommending action.
| Step | Question to answer | Practical consequence |
|---|---|---|
| Identify the document | Is it an assessment, reassessment, determination, request, or proposal? | Determines whether formal rights may need protection. |
| Check the date | What date appears on the notice or letter? | Determines deadline urgency. |
| Reconcile the amount | What amount changed from the return or prior position? | Shows tax, interest, penalty, loss, credit, or cash-flow exposure. |
| Read the reason | What factual or legal basis did CRA use? | Frames the taxpayer response. |
| Gather support | What records, schedules, agreements, or source law support the taxpayer? | Shows whether the position can be sustained. |
| Choose the path | Is the best next step clarification, adjustment request, objection, payment, or appeal planning? | Avoids overreacting or missing rights. |
Do not assume every CRA contact requires an objection. A request for information may be resolved by providing documents. A reassessment that changes tax payable may require a formal objection if informal discussion will not protect the taxpayer before the deadline.
The classification changes the advice.
| Situation | Better response |
|---|---|
| CRA asks for invoices supporting a deduction. | Provide organized support and explain how it ties to the return. |
| CRA issues a reassessment denying the deduction. | Review deadline, assess technical strength, and consider objection. |
| CRA proposes an audit adjustment before reassessment. | Respond with facts and law before the adjustment becomes assessed. |
| CRA assesses penalties. | Separate the tax issue from penalty relief or reasonable-care arguments. |
| CRA changes a loss or credit balance. | Consider whether the amount affects current or future tax positions. |
This distinction prevents a common exam error: writing a technical tax memo when the client first needs deadline protection or evidence triage.
Assessment review is partly a risk exercise. The taxpayer may be technically correct but still face a weak file, high professional fees, or a cash-flow problem.
| Risk area | What to evaluate |
|---|---|
| Technical strength | Does legislation, CRA guidance, case law, or professional analysis support the position? |
| Factual support | Are records complete, consistent, dated, and tied to the disputed amount? |
| Materiality | Is the amount worth the time and cost of dispute? |
| Interest and penalties | Does delay increase exposure if the taxpayer ultimately loses? |
| Disclosure risk | Could the response reveal broader issues in another year or account? |
| Relationship with CRA | Is the taxpayer trying to cooperate, correct, object, or litigate? |
| Cash flow | Can the taxpayer carry the disputed amount while the matter is reviewed? |
For corporation disputes, CRA notes that a formal objection is available when the corporation disagrees with tax, interest, or penalties assessed or reassessed. The public CRA corporation disputes page also states that relevant facts and supporting documents should be included with the objection.
Evidence should be connected to the precise adjustment. A broad document dump is weaker than a targeted response.
| Dispute type | Evidence to look for |
|---|---|
| Deduction denied | Invoices, contracts, payment proof, business purpose, allocation support. |
| Revenue timing | Agreements, delivery records, invoices, collection history, accounting policy. |
| Shareholder benefit | Corporate records, payments, personal-use evidence, reimbursement support. |
| GST/HST issue | Invoices, tax registration details, input tax credit support, place-of-supply facts. |
| Payroll or source deductions | Employment agreements, timesheets, remittances, benefits records, contractor analysis. |
| Penalties | Filing history, reasonable-care steps, adviser correspondence, system controls. |
When evidence is missing, the recommendation should say so. It may be better to request records, reconstruct support, or narrow the issue before filing a broad objection.
Use this structure for assessment review cases:
A strong answer balances rights protection with proportionality. Filing a formal objection may be necessary when the deadline is close or CRA has issued an assessment. It may be premature when CRA has only requested documents and the taxpayer has not yet supplied them. It may be impractical if the amount is small, evidence is weak, and the cost of dispute exceeds the likely benefit.
The recommendation should not sound like a template. Explain why the next step fits the facts.
| Pitfall | Correction |
|---|---|
| Arguing before classifying the CRA document. | Identify whether the taxpayer is dealing with a request, proposal, assessment, reassessment, or decision. |
| Treating informal discussion as deadline protection. | Preserve formal rights when an assessment deadline is at risk. |
| Ignoring the assessed amount. | Link the response to tax, interest, penalties, cash flow, and materiality. |
| Assuming evidence exists. | State which documents are needed and what weakness remains if they are unavailable. |
| Treating the dispute as purely technical. | Include cost, timing, reputation, and disclosure considerations. |
