Tax evasion questions test whether the candidate can distinguish illegal evasion from legitimate tax planning and from aggressive avoidance that may still create reputational or conduct risk. The core exam skill is classification: is the firm seeing a client tax issue, facilitation by an associated person, weak prevention procedures, or a broader financial-crime pattern?
The Criminal Finances Act 2017 angle matters because the firm can face risk when it fails to prevent facilitation of tax evasion by an associated person. A strong answer therefore looks beyond the customer’s tax position and asks whether staff, agents, introducers, or third parties helped another person evade tax.
| Pattern in the facts | Why it matters | Better exam response |
|---|---|---|
| client asks for false residency, ownership, or income information | may indicate evasion rather than planning | refuse to assist, preserve evidence, and escalate |
| introducer suggests hiding beneficial ownership | associated-person facilitation risk may arise | assess prevention procedures and third-party controls |
| offshore structure has no clear commercial purpose | may conceal taxable assets or income | check source of wealth, ownership, and tax rationale |
| employee helps alter documents | turns a client issue into firm governance and staff-conduct risk | investigate, escalate, and remediate controls |
| client cites “tax efficiency” without evidence | tax planning may be legitimate, but facts matter | distinguish lawful wrapper planning from dishonest concealment |
| Control area | What the exam wants you to see |
|---|---|
| risk assessment | where the firm is exposed to facilitation risk by products, clients, geographies, or intermediaries |
| proportional procedures | controls should match the risk profile rather than exist only as policy wording |
| due diligence | higher-risk clients, agents, and introducers need stronger evidence |
| communication and training | staff must know what facilitation risk looks like in practice |
| monitoring and review | procedures need testing and updating, not one-time approval |
| top-level commitment | senior management tone matters when tax-evasion facilitation creates business pressure |
| Lesson | Main review cue |
|---|---|
| Tax evasion, avoidance, and detection | Distinguish tax evasion from tax avoidance and explain why the legal and compliance implications differ materially |
| Criminal Finances Act 2017 and prevention procedures | Describe the broad purpose of the UK Criminal Finances Act 2017 corporate offences relating to failure to prevent the facilitation of tax evasion |
| If the case feels most like… | Better first move |
|---|---|
| lawful wrapper use or normal tax planning | do not overstate the issue; identify the legitimate tax-treatment point |
| false documents, hidden ownership, or concealed income | classify possible tax evasion and escalate |
| employee or introducer assistance | consider failure-to-prevent facilitation risk and prevention procedures |
| offshore or cross-border structure | test commercial rationale, beneficial ownership, and source of wealth |
| weak procedures or ignored red flags | focus on governance, training, due diligence, monitoring, and remediation |
A relationship manager helps a client describe an offshore account as belonging to a relative even though internal notes show the client controls the assets. The manager says the client only wanted “tax efficiency” and that the firm is not responsible for the client’s tax filing. What is the strongest concern?
Answer: B.
The facts suggest dishonest concealment and possible facilitation by an associated person. The firm should not treat this as ordinary tax efficiency. It should preserve evidence, escalate, and consider whether its prevention procedures and staff controls failed.
