Money Laundering Stages and Offences Explained

Updated 11 October 2026 · Fact-checked

Money laundering is the process of making money from crime look legitimate. It has three stages: placement (getting cash into the system), layering (hiding its origin through transactions) and integration (using the clean money). The main offences are laundering itself, failing to report suspicion and tipping off. Identify the stage or offence from the facts given.

Understand Money Laundering Stages and Offences

Money laundering means taking the proceeds of crime and disguising where they came from, so the money looks like it came from a legal source. Criminals do this because large amounts of unexplained cash attract attention. Clean money can be spent, invested or saved without raising questions.

The process is usually described in three stages. In placement, the dirty money first enters the financial system. Examples: paying cash into bank accounts in small amounts, buying goods with cash, or mixing cash with the takings of a cash-based business. This is the riskiest stage for the criminal, because the cash is physically in hand.

In layering, the criminal moves the money around to break the trail back to the crime. Examples: transfers between many accounts and countries, buying and selling assets, using shell companies, or sending money through complex ownership structures. The aim is confusion, not profit.

In integration, the money returns to the criminal as apparently legitimate wealth. Examples: buying property, running a genuine-looking business, or receiving a loan or payment from a company the criminal secretly controls. Once here, the money is very hard to tell apart from lawful funds.

The law creates criminal offences around this. Exact names and penalties differ by country, but ACCA tests the common ideas: laundering itself (concealing, transferring or acquiring criminal property), failing to report knowledge or suspicion, and tipping off (warning someone that a report has been made or an investigation is under way, so they can hide their activity). Accountants are exposed because they handle money, set up structures and see unusual transactions.

Key formulas to remember

Three stages of laundering: Placement → Layering → Integration; Placement puts cash into the system, layering hides the trail, integration returns the money as apparently legitimate wealth.
Laundering offence: Concealing, disguising, transferring or acquiring criminal property = offence; Applies when you know or suspect the property comes from crime. Exact wording varies by jurisdiction.
Failure to report: Knowledge or suspicion + no report to the nominated officer or authority = offence; In many jurisdictions, professionals in the regulated sector commit an offence if they fail to report. Internally, the report goes to the firm's money laundering reporting officer (MLRO).
Tipping off: Disclosing a report or investigation to the person concerned, likely to prejudice it = offence; The aim is to stop the suspect hiding evidence or moving money. Do not alert the client.

How to solve Money Laundering Stages and Offences questions

Use this method for any question on money laundering stages or offences.

1Read the scenario and underline what is happening to the money: cash in, moved around, or used.
2Match the action to a stage: cash entering the system is placement; moves and transfers to hide the trail is layering; money used as clean wealth is integration.
3If the question is about offences, ask who knows or suspects what, and what they then did.
4Decide whether the act is laundering (handling the property), failing to report (staying silent), or tipping off (warning the suspect).
5Check the exceptions: a proper report to the MLRO or authority is not tipping off.
6Choose the option that fits the facts exactly, not the one that merely sounds serious.
7For multiple response, count the required number of answers and check each option separately.

Quickest way: Three-word trigger method

When to use it: Use in Section A objective test questions where you have about two minutes or less.

Cash going in = placement.
Moving and hiding = layering.
Spending or investing as clean = integration.
For offences: handling = laundering; silence = failure to report; warning = tipping off.
Eliminate options that mix up the order of the stages or confuse reporting with tipping off.

Common mistakes in Money Laundering Stages and Offences

Putting the stages in the wrong order or mixing up layering and integration.
Both involve money moving, and both sound like the later step.
Fix: Remember that layering hides the trail and integration is when the criminal enjoys the money as clean. Think: in, hide, out.
Calling a cash deposit into a bank account layering.
Students focus on the bank account rather than the fact that cash is entering the system.
Fix: The first entry of cash into the financial system is always placement.
Thinking tipping off means reporting the client to the authorities.
The word 'tipping' is confused with informing the authorities.
Fix: Tipping off is warning the suspect. Reporting to the MLRO or authority is the required action, not the offence.
Believing you need proof of crime before you report.
Students assume reports need certainty.
Fix: Knowledge or suspicion is enough to trigger reporting. Investigation is for the authorities.
Assuming only criminals can commit laundering offences.
Students link the offence only to the original crime.
Fix: Professionals, such as accountants, can commit offences if they handle criminal property or fail to report suspicion.

Worked examples

Example 1

A criminal gang pays $4,000 in cash into each of ten bank accounts on the same day, then transfers the funds to a company overseas. Identify the stages shown.

Show the solution

The cash paid into ten accounts is cash entering the financial system. This is placement.
Splitting into small amounts avoids attention.
The transfer to an overseas company moves the money and hides its source. This is layering.
No step shows the money being used as clean wealth, so integration is not yet shown.

Answer: Placement (cash deposits), then layering (overseas transfer).

Example 2

An accountant suspects a client's funds come from crime and reports to the firm's MLRO. The accountant then tells the client that a report has been made. Which offence may the accountant have committed?

Show the solution

The accountant had suspicion and reported to the MLRO. This satisfies the duty to report, so failure to report does not apply.
Telling the client about the report warns the suspect.
This could allow the client to hide or move assets and prejudice an investigation.
That is tipping off.

Answer: Tipping off. The internal report was correct, but disclosing it to the client was the offence.

Exam tips

Learn the three stages with one example each. Scenario questions usually describe an action, not name the stage.
Read for the word 'cash'. Cash entering the system points to placement.
Separate the three offences clearly: handling, staying silent, and warning.
Never advise telling the client about a report. If a question asks what to do, the answer is to report to the MLRO and avoid alerting the client.
Link this topic to ethics. Questions may ask how confidentiality gives way to the duty to report.

Money Laundering Stages and Offences: frequently asked questions

What are the three stages of money laundering?

They are placement, layering and integration. Placement puts the cash into the financial system. Layering hides the trail through transactions, and integration returns the money as apparently legitimate wealth.

What is tipping off in money laundering?

Tipping off is telling a person that a suspicion report has been made or that an investigation is happening, in a way that could prejudice it. It is an offence because it lets the suspect hide evidence or move funds.

Do I need proof before reporting suspected money laundering?

No. Knowledge or suspicion is generally enough to trigger the duty to report. You report to your MLRO or the relevant authority, and they decide on further action.

Why are accountants at risk of money laundering offences?

Accountants handle money, advise on structures and see transactions in detail. This makes them useful to launderers and exposes them to offences if they assist or fail to report suspicion.
