When the CRA Demands an Interview: The Expanding Power to Compel Answers During a Tax Audit

A Canada Revenue Agency audit is no longer confined to the production of books, records and supporting documents. The CRA may now require a taxpayer, an employee, an accountant or another person to attend an interview and answer questions orally. It may also dictate that questions be answered in writing and specify the form of the response.

This is a significant change in Canadian tax administration. It alters both the legal obligations imposed on taxpayers and the practical risks associated with an audit. A poorly handled interview can give the CRA evidence that did not previously exist, expose inconsistencies among witnesses, undermine an otherwise defensible filing position and provide the factual foundation for gross negligence penalties or even a criminal investigation.

The important question is no longer simply whether a taxpayer must cooperate. The real question is how the taxpayer can comply without surrendering control of the evidentiary record.

The Law Before the Amendment

The starting point is the Federal Court of Appeal’s decision in Canada (National Revenue) v. Cameco Corporation, 2019 FCA 67.

During its transfer pricing audit of Cameco, the CRA sought to interview approximately 25 employees. It wanted oral answers concerning the company’s business activities, transactions, organizational structure and decision making. Cameco agreed to provide information in writing but disputed the CRA’s authority to compel its employees to submit to oral interviews.

The Federal Court of Appeal agreed with Cameco. The version of paragraph 231.1(1)(d) of the Income Tax Act then in force required a taxpayer and its personnel to provide “all reasonable assistance” and to answer “all proper questions” relating to the administration or enforcement of the Act. The Court held that these words did not give the CRA an unrestricted right to compel individuals to attend oral interviews.

The decision drew an important distinction between requiring information and compelling a particular method of obtaining it. Cameco remained obligated to provide relevant information, but the CRA could not insist that its employees sit for interviews merely because oral questioning was more convenient or potentially more revealing.

That distinction has now largely disappeared.

Parliament’s Response to Cameco

Parliament amended section 231.1 of the Income Tax Act in 2022. Paragraph 231.1(1)(d) now expressly authorizes an auditor to require a taxpayer or any other person to provide reasonable assistance, answer all proper questions and:

1. attend with the auditor at a designated place, by videoconference or through another form of electronic communication, and answer questions orally; and
2. answer questions in writing in any form specified by the auditor.

The amendment was an unmistakable response to Cameco. Parliament did not merely confirm that the CRA could ask questions. It gave the CRA substantial control over the manner in which answers must be provided.

The current provision is also broader than many taxpayers appreciate. It is not limited to the person whose return is under audit. The CRA may direct questions to “a taxpayer or any other person.” Depending on the circumstances, this may include officers, directors, employees, bookkeepers, accountants, transaction participants and other persons believed to possess relevant information.

This does not turn an audit interview into an examination for discovery. There is no judge supervising the questioning, no transcript unless one is created, no defined pleading that limits the issues and no automatic right to correct an improvident answer later. Yet the answers may become important evidence in an objection, a Tax Court appeal, a penalty dispute or a subsequent investigation.

That combination makes the audit interview unusually consequential.

What Is a “Proper Question”?

The CRA’s authority is broad, but it is not unlimited. Section 231.1 permits questions relating to the administration or enforcement of the Income Tax Act, and only “proper questions” must be answered.

The word “proper” must perform some limiting function. A question should have a rational connection to an identifiable tax issue, period, transaction or statutory obligation. An auditor should not be entitled to demand speculation, compel a witness to adopt the auditor’s legal characterization or conduct an unlimited inquiry into matters having no discernible relationship to the audit.

For example, there is a meaningful difference between asking who authorized a particular payment and asking whether the witness agrees that the payment constituted a shareholder benefit. The first seeks a fact. The second asks the witness to accept a legal conclusion that may depend on purpose, corporate authority, accounting treatment and the application of subsection 15(1).

Similarly, an auditor investigating a property disposition may properly ask when the property was acquired, how it was used, who occupied it and why it was sold. It is more problematic to demand that the taxpayer agree, during an interview, that the taxpayer had a “secondary intention” to resell the property at a profit. That language imports a legal doctrine into what should be a factual inquiry.

Taxpayers should not refuse questions casually. An unjustified refusal may cause the Minister to seek a compliance order under section 231.7. The better approach is to identify the concern precisely, request that the question be clarified and, where appropriate, provide the underlying facts without accepting a disputed legal premise.

The Risk of Creating the CRA’s Case

Documents generally record events when they occur. Interview answers are different. They are produced after the audit has begun, often years after the relevant transaction, in response to questions designed by the auditor.

Memory is imperfect. Business owners frequently use shorthand, approximate dates or describe complex transactions in commercially sensible but legally imprecise terms. An answer that sounds harmless in conversation may later be treated as an admission.

This is particularly dangerous where the assessment depends on intention or credibility. Cases involving shareholder benefits, unreported income, real estate trading, alleged sham transactions, director liability and gross negligence penalties often turn on what the taxpayer knew, intended or believed. The auditor may use an interview to bridge gaps in the documentary record.

Consider an owner who says that personal expenses were “sometimes” paid through the corporation. That answer may be understood merely as an acknowledgment of the company’s payment process. The CRA may instead treat it as evidence of an appropriation of corporate funds. If the owner later explains that every payment was charged to the shareholder loan account, the auditor may portray the more precise answer as a retreat from the original admission.

The same risk arises when several people are interviewed separately. Minor differences in recollection can be characterized as contradictions even where each witness is honestly describing the transaction from a different perspective.

The objective should therefore be accuracy, not spontaneity. A tax audit is not a test of conversational fluency.

Preparation Is Not Coaching

A witness should never be told what to say. That does not mean the witness should enter an audit interview unprepared.

Proper preparation includes reviewing the relevant returns, agreements, correspondence, bank records and accounting entries. It includes identifying which events the witness personally observed and which matters were handled by someone else. It also includes distinguishing present recollection from information reconstructed from documents.

A witness should be prepared to say, where truthful, “I do not recall,” “I would need to review the records,” or “That decision was made by someone else.” These are legitimate answers. Guessing is not cooperation. It is the creation of unreliable evidence.

Preparation should also address terminology. Words such as “loan,” “dividend,” “distribution,” “gift,” “reimbursement” and “investment” have legal consequences that may not correspond with their casual business usage. A witness should describe what actually happened rather than attach a legal label to a transaction.

Where the audit concerns a corporation, it is also essential to determine who can speak to each subject. The person who negotiated a transaction may not know how it was recorded. The accountant who recorded it may not know why it occurred. Requiring one person to answer every question invites speculation and error.

Counsel’s Role in the Interview

Legal counsel should ordinarily be involved before a consequential CRA interview and, where appropriate, attend it.

Counsel’s function is not to obstruct the audit. It is to ensure that the interview remains within its lawful scope, that ambiguous questions are clarified, that privileged communications are protected and that the witness is not pushed into speculation or legal conclusions.

Before the interview, counsel should request the subject matter, periods under review, proposed participants and anticipated areas of questioning. If the CRA intends to question several people, the taxpayer should understand why each person is being requested and what information the auditor believes that person possesses.

A reliable record should also be created. At minimum, detailed contemporaneous notes should be taken. For significant audits, the parties should consider whether the interview will be recorded or transcribed. Disputes about what was said are difficult to resolve after an assessment has been issued.

Following the interview, any material factual error should be corrected promptly and in writing. A correction made before the auditor completes the proposal is more persuasive than an explanation offered for the first time during litigation.

Privilege Remains a Boundary

The expansion of the CRA’s interview power did not eliminate solicitor client privilege.

Section 232 of the Income Tax Act recognizes solicitor client privilege, and the Supreme Court of Canada has repeatedly described the privilege as a principle of fundamental justice that must remain as close to absolute as possible. The CRA cannot compel disclosure of confidential communications made for the purpose of obtaining or providing legal advice merely by framing its demand as an audit question.

The boundary requires care. The underlying facts of a transaction are not privileged simply because they were communicated to a lawyer. The legal advice concerning those facts may be privileged.

A taxpayer may therefore be required to explain what was done, when it was done and who participated. The taxpayer should not be required to disclose what counsel advised about the transaction, the legal risks counsel identified or the content of communications prepared for the purpose of seeking legal advice.

Privilege should be asserted precisely. A blanket refusal to discuss an entire transaction merely because lawyers were involved is unlikely to be sustainable. Equally, a taxpayer should not waive privilege inadvertently by volunteering legal advice as an explanation for its conduct.

When an Audit Begins to Look Like an Investigation

A further limit arises when the CRA’s predominant purpose shifts from determining civil tax liability to investigating an offence.

In R. v. Jarvis, 2002 SCC 73, the Supreme Court of Canada held that the CRA cannot continue using its administrative audit powers to gather evidence after the predominant purpose of the inquiry has become penal liability. Once that threshold is crossed, the taxpayer is entitled to the protections that ordinarily apply in a criminal investigation.

There is no single fact that marks the transition. Relevant considerations include whether the auditor has reasonable grounds to believe an offence was committed, whether the matter has been referred to investigators, whether the auditor’s conduct is consistent with an ordinary civil audit and whether the information is being sought primarily to support a prosecution.

The mere possibility of penalties does not transform an audit into a criminal investigation. Gross negligence penalties under subsection 163(2), although serious, remain civil. Nevertheless, sudden questions concerning intentional concealment, fabricated documents, false statements or the taxpayer’s knowledge of reporting obligations should be treated with care.

Where the direction of the inquiry changes materially, counsel should ask whether the matter remains a civil audit, whether Criminal Investigations is involved and for what purpose the interview is being conducted. The answer may determine whether continued compulsory questioning is lawful.

Noncompliance Is Not a Strategy

Taxpayers sometimes respond to an aggressive audit by refusing to engage. That approach is usually counterproductive.

Under section 231.7, the Minister may seek a compliance order from the Federal Court where a person has failed to provide access, assistance, information or documents as required under sections 231.1 or 231.2. A failure to comply with the resulting court order can lead to contempt proceedings. The Act also contains offence provisions relating to noncompliance.

More immediately, silence leaves the auditor’s assumptions unanswered. If the records are incomplete and the taxpayer supplies no coherent explanation, the CRA may use indirect verification methods, deny deductions, characterize deposits as income or impose gross negligence penalties.

Effective resistance is disciplined rather than absolute. The taxpayer should comply with lawful requests, preserve objections to improper ones, protect privilege and maintain control over the accuracy of the record.

The Practical Lesson

The 2022 amendment to section 231.1 shifted the balance of power during a CRA audit. The taxpayer can no longer rely on Cameco as a general basis for insisting that all questions be answered in writing. The CRA may compel attendance and oral answers.

That does not mean an auditor is entitled to an unstructured conversation with every person connected to the taxpayer. Questions must remain proper and related to the administration or enforcement of the Act. Privilege continues to apply. Administrative powers cannot be used principally to build a criminal prosecution. Taxpayers may obtain advice, prepare witnesses, seek clarification and create an accurate record.

The central mistake is to treat the interview as an informal meeting. It is an evidence gathering process conducted by the authority that may later reassess the taxpayer, plead assumptions of fact and defend those assumptions in court.

Key Takeaways

First, determine the scope before anyone is interviewed. Identify the issues, taxation years, proposed witnesses and subjects on which each witness is expected to have personal knowledge.

Second, prepare from the documents. The safest answer is an accurate answer grounded in contemporaneous records. Witnesses should distinguish knowledge, recollection and assumption, and should never guess merely to appear cooperative.

Third, protect the record. Counsel should address improper questions, preserve privilege, document the answers given and correct material inaccuracies before they become embedded in the audit working papers or the Minister’s assumptions.

An audit interview may last only a few hours. Its consequences can shape the dispute for years.
