Picture an alert on a personal account. Checks made out to the customer and to the customer's own businesses keep arriving, and the income the customer declared cannot explain them. Before anyone writes the case note, the file has to answer the question an examiner will ask, or an auditor in the UK and EU: is this money laundering, tax evasion or both, and which law decides? The answer changes from one country to the next, and so does what the firm must report. Under the FATF standard, tax crime is one of the predicate offenses that feed the money laundering methods and typologies a monitoring team watches for. US federal law handles it another way.
What is the difference between money laundering and tax evasion?
Tax evasion hides income from the tax authority, while money laundering hides where money came from (Table 1).
Table 1. Tax evasion and money laundering compared
| Question | Tax evasion | Money laundering |
|---|---|---|
| What the crime is | Willfully evading or defeating a tax that is due | Concealing, converting or moving the proceeds of crime so that their origin is hidden |
| Where the money comes from | Often lawful income or assets; sometimes criminal income left off a return | Always the proceeds of a crime, the predicate offense |
| What is hidden, and from whom | Income or assets, from the tax authority | The criminal origin of the money, from banks, authorities and anyone tracing it |
| Who investigates | The tax authority's criminal investigators: IRS Criminal Investigation in the US, HMRC in the UK | Police and prosecutors, working from reports that banks and other obliged firms file with the financial intelligence unit |
| Main US statute | 26 USC 7201, a felony | 18 USC 1956 |
| Main UK law | Cheating the public revenue, and offenses of being knowingly concerned in the fraudulent evasion of a tax (Criminal Finances Act 2017, s45(4)) | Proceeds of Crime Act 2002, ss. 327 to 329 |
In a tax evasion case the money can be clean: fees, wages or sales earned lawfully and then left off a return. The crime is hiding that income from the tax authority on purpose. US law needs one line for it: a person who "willfully attempts in any manner to evade or defeat any tax" commits a felony under 26 USC 7201. Evasion is the criminal core of tax fraud, the wider term for any intentional deception about tax.
In a money laundering case the money is dirty from the start, and the crime is what happens to it next. Fraud, drug trafficking or an illegal gambling business produces it, and laundering moves, converts or hides it until it looks earned.
Tax avoidance sits outside both. Arranging affairs to pay less tax within the law is lawful, so it creates no criminal property and leaves nothing to launder.
Is tax evasion money laundering? The answer by jurisdiction
It depends on the law. FATF, EU, UK and, above a threshold, Swiss rules make tax crime a predicate offense; US federal law does not.
Table 2. Is tax evasion a predicate offense? As of November 2026
| Jurisdiction | Predicate offense? | The rule | Since | What it means for a report |
|---|---|---|---|---|
| FATF standard | Yes | Tax crimes on direct and indirect taxes are a designated category; each country defines the offense | February 2012 (absent from the 2003 list) | Countries must be able to treat tax crime proceeds like any other criminal proceeds |
| EU | Yes | Directive (EU) 2018/1673, art. 2(1)(q): tax crimes as national law defines them; also any offense with a maximum sentence above one year | Directive of 23 October 2018 | Proceeds of a national tax crime are criminal property for a laundering report |
| UK | Yes | POCA s340: benefit from any criminal conduct; tax saved counts as a sum of money | Proceeds of Crime Act 2002 | Undeclared income kept by evasion can trigger the s330 duty to disclose |
| US | No | Tax evasion is not a specified unlawful activity (18 USC 1956(c)(7), 1961(1)); a transaction in a listed crime's proceeds made with intent to evade tax is laundering (1956(a)(1)(A)(ii)) | Not on the list as of November 2026 | A bank still files a SAR at $5,000 or more when funds may come from illegal activity |
| Switzerland | Yes, for tax fraud above CHF 300,000 | Tax fraud under the federal direct tax or tax harmonization act, more than CHF 300,000 evaded in a tax period (Criminal Code art. 305bis 1bis) | 1 January 2016 | Direct tax fraud counts as a predicate only above the threshold, per tax period |
FATF's Forty Recommendations of 2003 listed the categories of offenses every country had to cover, and tax crime was not among them. Its interpretive note still told financial institutions to report suspicious transactions "regardless of whether they are also thought to involve tax matters". The Recommendations adopted in February 2012 added "tax crimes (related to direct taxes and indirect taxes)". Each country defines the offense itself, which is why the rows differ.
In the EU, Directive (EU) 2018/1673, known as 6AMLD, lists "tax crimes relating to direct and indirect taxes" among the criminal activities whose proceeds can be laundered and leaves their definition to each member state. An offense whose maximum prison term is above one year counts too.
The UK takes an all crimes approach. The Proceeds of Crime Act 2002 defines criminal property in section 340 as a benefit from criminal conduct, which is any conduct that is an offense in the UK or would be one if it happened there. A pecuniary advantage counts as a sum of money equal to its value. A customer who evades tax therefore holds criminal property equal to the tax not paid, even when the income was earned lawfully.
US federal law is the exception. A laundering charge under 18 USC 1956 needs the proceeds of a "specified unlawful activity", and that list (section 1956(c)(7), which takes in the racketeering offenses of section 1961(1)) names no tax offense. Tax comes in through one prong. Under section 1956(a)(1)(A)(ii), a transaction in such proceeds is laundering when it is conducted to commit tax evasion or a false return offense under section 7201 or 7206. A bank's reporting duty under the AML rules in the United States is a separate test, met by a suspicion of any illegal activity.
Switzerland set a threshold. Since 1 January 2016, article 305bis of the Swiss Criminal Code has covered assets from an "aggravated tax misdemeanour": the tax fraud offenses of the federal direct tax act and the tax harmonization act, where the tax evaded in any tax period exceeds CHF 300,000. The rule implemented FATF's 2012 revision, and banks apply it inside the wider AML rules in Switzerland.
Three ways tax evasion and money laundering meet
Criminal income that was never declared
On 9 June 2026 a California man was sentenced to 27 months in prison for tax evasion, operating an illegal gambling business and money laundering, according to the Department of Justice. The business was run from offshore, and between $1.5 million and $3.5 million of its cash was exchanged for checks made out to the defendant or the defendant's businesses. The 2020 return reported no taxable income on about $1.8 million earned, and over the years tax was evaded on about $4.2 million of income.
The gambling profits were the proceeds of a crime, so turning them into checks was laundering. They were also taxable income, and leaving them off the return was evasion.
Lawful income hidden from the tax authority
Picture an illustrative consultant whose foreign clients pay fees into an account abroad that no tax return mentions. The fees are clean. The tax due on them is unpaid, and in the UK that unpaid tax is a benefit from crime: the money that represents it is criminal property, and moving it is laundering. Some call this tax laundering. In the US the same facts make a tax case unless another listed crime is involved.
A bank sees the mismatch first, as account activity that declared income cannot explain. complead, formerly Sanction Scanner, lets a firm make that mismatch a factor in its own customer risk assessment model, using factors, weights and thresholds that the firm chooses. When the score reaches the firm's chosen level, enhanced due diligence opens with the factors that put it there.
The hiding place is often offshore: a company or account in another jurisdiction, held in a nominee's name, the kind of structure the Panama Papers exposed.
Laundering the proceeds of a fraud on the treasury
Here the tax system is the victim. On 3 September 2026 the Department of Justice announced a superseding indictment charging seven people, an Idaho man and woman and five people from outside Idaho, with conspiracy to commit wire fraud, making false claims and money laundering. The indictment alleges refund claims totaling more than $57 million, more than $8 million received from the IRS, and laundering through purchases such as luxury cars bought with the refunds. These are allegations.
The predicate is the fraud. Wire fraud is a specified unlawful activity in US law, so a laundering count can rest on it although tax evasion is not on the list. In the indictment's account the refund claims made the money and the car purchases moved it, the usual split between fraud and money laundering.
Can you be charged with money laundering and tax evasion at the same time?
Yes. They are separate offenses with separate elements, so one set of facts can support both counts, and the prosecution has to prove each one.
In the US there are two routes. One is the tax intent prong: a transaction in a listed crime's proceeds, carried out to evade tax or to file a false return. The other is to charge laundering on the underlying crime, such as an illegal gambling business or wire fraud, both listed under section 1961(1), and add a separate count under section 7201. The 9 June 2026 sentence covered all three crimes; the 3 September indictment pairs laundering with wire fraud.
In the UK the chain is shorter. The tax saved is criminal property, so a person who conceals, converts or transfers it commits an offense under section 327 of the Proceeds of Crime Act as well as the tax offense.
A tax case can also stand alone, with no laundering count. On 17 October 1931 a federal jury convicted Al Capone of tax evasion.
What does a suspicion of tax evasion mean for your AML program?
An AML program cannot prove tax evasion or stop it. It finds the accounts where untaxed or criminal money may sit and passes them to whoever decides on a report. Five checks raise a tax suspicion:
- Income that does not fit the customer. The US rule for bank reports counts a transaction that the particular customer would not normally be expected to make as a ground for suspicion. Deposits far above declared income fit that description.
- Source of funds and source of wealth at onboarding. Where the money came from, with evidence, is the baseline later activity is measured against.
- Tax crime in adverse media. A criminal case or penalty for evaded tax is negative news, and an adverse media check puts "tax evasion" and "tax fraud" among its search terms.
- Offshore and nominee structures. A company abroad that holds the customer's money in someone else's name is a common vehicle for hiding lawful income.
- CRS and FATCA data. When a self certification names one country of tax residence and the money moves through another, ask the customer before drawing any conclusion. Under FATCA, foreign banks already report accounts held by US persons.
A hit on any of the five goes to the MLRO, who weighs it with the rest of the file.
Do you have to report suspected tax evasion?
Yes, when the suspicion meets the reporting test. For a US bank the test is in 31 CFR 1020.320: a SAR is due for a transaction of $5,000 or more where the bank "knows, suspects, or has reason to suspect" that it moves funds from illegal activity, or where the transaction has no apparent lawful purpose. The rule speaks of illegal activity in general, so the report does not wait for anyone to name the crime.
In the UK, a person in the regulated sector who knows or suspects, or has reasonable grounds to suspect, that someone is laundering must disclose it (Proceeds of Crime Act, section 330). Evaded tax is criminal property, so a customer who holds or moves it can be laundering.
Staff report to the MLRO, who decides on SAR filing with the National Crime Agency. Telling the customer can be tipping off under section 333A.
Your own staff: failing to prevent the facilitation of tax evasion
Since 30 September 2017, a company or partnership, wherever it was formed, commits an offense when a person acting for it, such as an employee or an agent, criminally facilitates someone else's evasion of UK tax (Criminal Finances Act 2017, section 45). The firm has a defense if it can prove it had reasonable prevention procedures in place. Section 46 reaches foreign tax when the firm is incorporated in the UK, does business there, or part of the conduct happens there. On conviction on indictment the penalty is a fine, and the act sets no maximum for it.
HMRC's guidance on the corporate offenses builds those procedures on six principles:
- Risk assessment. Document where the people who act for the firm could facilitate tax evasion, and keep that assessment under review.
- Proportionality of procedures. The procedures match the risk the firm faces.
- Top level commitment. Senior management commits to prevention and sets a culture where facilitation is never acceptable.
- Due diligence. Risk based checks on anyone who performs services on the firm's behalf.
- Communication and training. The policy is communicated and understood across the firm.
- Monitoring and review. The procedures are reviewed and improved as the risks change.
Tax evasion sits beside fraud, bribery and money laundering among the financial crimes a compliance program covers, and the six principles can run inside the same framework.
What changed in 2026
The dated record for 2026 so far:
- 1 January. The EU's DAC8 began to apply and brought crypto asset operators into tax reporting; amended Common Reporting Standard rules took effect in the EU on the same day.
- 7 April. The Department of Justice announced its National Fraud Enforcement Division. The division's Tax Section is prosecuting the 3 September refund case and took part in the October surge.
- 9 June. One sentence of 27 months covered tax evasion, an illegal gambling business and money laundering.
- 3 September. A superseding indictment charged laundering on the proceeds of an alleged tax refund fraud.
- 14 October. DOJ's first National Tax Enforcement Surge reached 76 defendants whose alleged and proven crimes intended an estimated loss to federal revenue of more than $490 million.
The 9 June case had both facts. Cash was exchanged for checks made out to the defendant or the defendant's businesses, and the 2020 return reported no taxable income on about $1.8 million earned. Income that does not fit the customer is the check that would raise it. In the US the bank reporting rule makes such a file reportable at $5,000. In the UK the evaded tax alone makes the balance criminal property, and once someone in the regulated sector suspects it, the report is a duty.
