Tax Evasion as a Predicate Offence

1. Why This Topic Matters

For most of the twentieth century, tax evasion sat outside the anti-money laundering (AML) framework. Many countries treated tax matters as a purely domestic, civil or administrative concern, and international cooperation was blocked by the so-called fiscal offence exception, which allowed a jurisdiction to refuse mutual legal assistance if the request related to taxes. Banking secrecy in jurisdictions such as Switzerland, Luxembourg and various offshore centres thrived on this gap.

That changed dramatically after the 2008 financial crisis, the UBS case in the United States, the LGT/Liechtenstein data leak, and later the Panama Papers and Paradise Papers. Governments realised that undeclared offshore wealth was both a revenue problem and a money laundering problem, because the same secrecy structures that hide untaxed income also hide the proceeds of corruption, fraud and organised crime.

In 2012 the Financial Action Task Force (FATF) revised its 40 Recommendations and formally added tax crimes (related to direct and indirect taxes) to the list of designated categories of offences that every country must treat as predicate offences for money laundering. From that point on, every FATF-compliant AML programme has had to consider tax evasion as a source of criminal proceeds. For the CAMS candidate, this is why the topic is heavily examined: it changed what counts as 'dirty money', widened suspicious activity reporting obligations, and reshaped customer due diligence on wealthy and cross-border clients.

2. What Is a Predicate Offence?

A predicate offence (sometimes called a predicate crime or underlying offence) is the criminal activity that generates the proceeds which are then laundered. Money laundering is a derivative crime: there can be no laundering without an earlier offence that produced illicit funds. Drug trafficking, fraud, corruption, human trafficking and terrorism financing are classic predicate offences. Tax evasion is now universally recognised as one as well.

Countries define predicate offences in one of three ways, and the exam expects you to recognise all three:

- All-crimes approach: any criminal offence can be a predicate for money laundering. The United Kingdom (Proceeds of Crime Act 2002) is the leading example. Under this model, tax evasion has always been a predicate offence.
- Threshold approach: offences punishable above a minimum penalty (for example, imprisonment of more than one year) qualify.
- List approach: a specific schedule of offences is enumerated. FATF requires that any list include, at minimum, the designated categories, which since 2012 include tax crimes.

Some jurisdictions combine approaches. The European Union's Sixth AML Directive (6AMLD) harmonised a list of 22 predicate offences across member states, explicitly including tax crimes relating to direct and indirect taxes, following the Fourth AML Directive which first introduced them in 2015.

3. Tax Evasion versus Tax Avoidance

This distinction appears repeatedly in CAMS questions.

- Tax evasion is the illegal non-payment or underpayment of tax by deliberately misrepresenting or concealing the true state of one's affairs: hiding income, inflating deductions, failing to file, using undeclared offshore accounts, or falsifying invoices. It is a crime and therefore a predicate offence.
- Tax avoidance is the legal use of tax law to minimise liability, such as claiming legitimate reliefs or structuring a business efficiently. It is not a crime. However, aggressive avoidance schemes can cross the line into evasion when they involve sham transactions or deliberate concealment, and they can raise reputational risk for a financial institution even when technically lawful.

The exam distinction: avoidance is lawful planning within the rules; evasion is unlawful concealment or misrepresentation. Only evasion generates criminal proceeds.

4. How Tax Evasion Generates Laundered Proceeds

A conceptual challenge unique to tax evasion is identifying the 'proceeds'. With drug trafficking, the entire revenue is criminal. With tax evasion, the underlying income (salary, business profits, investment gains) may be perfectly legitimate. The criminal proceeds are the tax that should have been paid but was not, together with any funds that have been concealed to achieve the evasion. Many legal systems treat the entire concealed sum as criminal property because it has been handled with intent to defraud the revenue authority. The key point for AML purposes is that legally earned money can become criminal property through the act of evasion.

The three classic stages of laundering map onto tax evasion as follows:

- Placement: undeclared cash receipts from a business are deposited in small amounts (structuring), or income is routed directly to an offshore account never disclosed to the home tax authority.
- Layering: funds move through shell companies, trusts, foundations or nominee arrangements in secrecy jurisdictions; false or inflated invoices between related entities shift profit to low-tax or no-tax locations; loans are fabricated so that repatriated money looks like borrowed capital.
- Integration: the untaxed wealth returns as property purchases, 'loans' from offshore entities, investments, or credit cards drawn on offshore accounts, giving the appearance of legitimate wealth.

5. Common Typologies

- Undeclared offshore accounts held directly or through private investment companies, often in jurisdictions with strong secrecy laws.
- Shell and shelf companies with nominee directors and shareholders, bearer shares (where still permitted), and opaque beneficial ownership.
- Trade-based schemes: over-invoicing and under-invoicing, phantom shipments and misdescription of goods to move value across borders and evade customs duties or corporate tax.
- VAT carousel / Missing Trader Intra-Community (MTIC) fraud: goods are traded rapidly across borders through a chain of companies; one trader collects VAT and disappears without remitting it to the authorities. This is a form of indirect tax crime explicitly covered by FATF's 2012 expansion.
- Cash-intensive businesses that skim receipts before they reach the books.
- Payroll and employment tax evasion through off-the-books workers or misclassification.
- Abuse of life insurance wrappers, foundations and discretionary trusts to disguise ownership of income-producing assets.
- Citizenship and residence by investment programmes used to obtain documentation that misleads financial institutions about true tax residency.

6. The International Tax Transparency Framework

CAMS candidates should know the main instruments that have reduced the space for cross-border tax evasion:

- FATF Recommendations (2012): tax crimes designated as predicate offences; removal of the fiscal offence exception as a ground for refusing cooperation.
- FATCA (US Foreign Account Tax Compliance Act, 2010): requires foreign financial institutions to identify and report accounts held by US persons or face 30 percent withholding.
- OECD Common Reporting Standard (CRS): a multilateral regime for automatic exchange of financial account information among more than 100 jurisdictions, modelled on FATCA.
- EU AML Directives: 4AMLD introduced tax crimes as predicates and created beneficial ownership registers; 6AMLD harmonised the predicate offence list and extended liability to legal persons.
- UK Criminal Finances Act 2017: created corporate offences of failure to prevent the facilitation of tax evasion, both domestic and foreign, placing a direct compliance burden on banks, accountants and lawyers.
- Beneficial ownership transparency initiatives, which target the nominee and shell company structures that both tax evaders and other launderers rely upon.

Note the position of the United States: while US courts and statutes have historically approached tax evasion differently from a generic 'specified unlawful activity', US money laundering law does capture conduct intended to violate the Internal Revenue Code, and US institutions are expected to file Suspicious Activity Reports where tax evasion is suspected. The exam may test the general principle that jurisdictions differ in how they incorporate tax crimes, rather than fine statutory detail.

7. Implications for Financial Institutions

Once tax evasion is a predicate offence, an institution that handles the proceeds may itself commit money laundering if it knows or suspects the source. Practical consequences:

- Customer due diligence must capture tax residency, source of wealth and source of funds, particularly for high-net-worth, private banking and cross-border clients.
- Enhanced due diligence is warranted for complex offshore structures, trusts with no clear commercial purpose, and clients linked to secrecy jurisdictions.
- Suspicious activity reporting: an institution does not need to prove that tax evasion occurred. A reasonable suspicion that funds are the proceeds of a tax crime is enough to trigger a report, and the institution must not tip off the client.
- Dual criminality and foreign tax evasion: proceeds of tax evaded in another country are generally treated as criminal property in the reporting jurisdiction, provided the conduct would be criminal in both places.
- Governance: tax evasion risk must be built into the enterprise-wide risk assessment, product approval, and training. Compliance, legal and tax functions should coordinate.
- Reputational and regulatory risk: major banks have paid multi-billion-dollar penalties for facilitating client tax evasion, and individual bankers have faced prosecution.

8. Red Flags Associated With Tax Evasion

- Reluctance or refusal to provide tax identification numbers, tax residency, or self-certification forms.
- Requests to hold mail, suppress statements, or avoid correspondence to the client's home country.
- Use of shell companies, nominees or bearer instruments with no apparent commercial rationale.
- Wealth or lifestyle inconsistent with declared income.
- Structuring deposits below reporting thresholds.
- Frequent round-trip transactions between an individual and an offshore entity he or she controls, often described as 'loans' or 'consulting fees'.
- Invoices that do not match goods, prices far from market value, or trading in sectors known for VAT fraud (mobile phones, computer chips, carbon credits, precious metals).
- Rapid pass-through of funds by newly formed companies with minimal staff or premises.
- Interest in jurisdictions specifically because they do not participate in CRS or have weak beneficial ownership rules.
- Client asks whether information will be shared with tax authorities before opening an account.

9. Exam Tips: Answering Questions on Tax Evasion as a Predicate Offence

Tip 1 - Anchor on FATF 2012. If a question asks when or why tax crimes became an international AML concern, the answer is the 2012 revision of the FATF Recommendations, which added tax crimes relating to direct and indirect taxes to the designated categories of predicate offences.

Tip 2 - Know the three approaches to defining predicates. Expect scenario questions describing a country's legal framework and asking whether tax evasion qualifies. Under an all-crimes approach it always does; under a list approach it does if listed (and FATF requires it to be listed); under a threshold approach it depends on the penalty.

Tip 3 - Evasion is illegal, avoidance is legal. Any option that treats lawful tax planning as a predicate offence is wrong. Any option that treats deliberate concealment of income as 'merely avoidance' is also wrong. Look for words such as conceal, misrepresent, undeclared or false to identify evasion.

Tip 4 - Legitimate income can become criminal property. A frequent distractor states that funds earned lawfully cannot be laundered. Remember that the act of evading tax on legitimate income creates criminal proceeds.

Tip 5 - Suspicion, not proof. Questions about the compliance officer's duty are answered by 'file a suspicious activity report and do not tip off'. The institution is never expected to calculate the tax owed or prove the offence; that is the role of the tax authority and law enforcement.

Tip 6 - Link typologies to indirect tax. VAT carousel or MTIC fraud is the classic indirect tax crime. Trade-based money laundering indicators (over- and under-invoicing) frequently appear in tax-related scenarios. Recognise them as tax crimes, not just trade fraud.

Tip 7 - Connect to transparency regimes. FATCA relates to US persons; CRS is the OECD multilateral equivalent; beneficial ownership registers come from the EU directives and FATF Recommendation 24 and 25. Questions may ask which instrument addresses a specific gap.

Tip 8 - Cross-border questions test dual criminality and the end of the fiscal offence exception. The modern position is that countries should not refuse to cooperate simply because the underlying offence is a tax matter.

Tip 9 - Choose the most complete risk-based answer. When a scenario describes an offshore structure with nominees and a reluctant client, the best answer usually involves enhanced due diligence on source of wealth and beneficial ownership, escalation to compliance, and consideration of a report. Avoid extreme options such as immediately closing the account without review, or accepting the client's explanation without verification.

Tip 10 - Read for the role being tested. CAMS questions often specify whether you are a front-line banker, a compliance officer, or an investigator. The correct action differs: a banker escalates internally; a compliance officer assesses and reports; an investigator traces beneficial ownership and liaises with authorities.

10. Key Takeaways

- Tax evasion is now a globally recognised predicate offence for money laundering, driven by FATF's 2012 Recommendations and reinforced by the EU directives, FATCA and CRS.
- The proceeds of tax evasion are the concealed, untaxed funds; legitimate origins do not cleanse them.
- Distinguish evasion (criminal) from avoidance (lawful), and recognise both direct and indirect tax crimes, including VAT fraud and customs evasion.
- Financial institutions must incorporate tax evasion into risk assessments, CDD, EDD, monitoring and suspicious activity reporting, and must never tip off.
- In the exam, prioritise FATF principles, the suspicion threshold, the risk-based approach and the avoidance versus evasion distinction when selecting the best answer.
