Preface
The purpose of this handbook is to raise the awareness level of tax examiners and auditors
on money laundering. It provides guidance in identifying money laundering during the
conduct of normal tax audits. It also describes the resources and tools that are available for
effective detection and deterrence. While the handbook does not detail criminal investigation
methods, it does describe the nature and context of money laundering activities so that tax
examiners and auditors can better understand how their contribution can assist criminal
investigators in countering money laundering.
Tax administrations can adapt the handbook to suit their particular circumstances and
to take into account the varying roles that tax administrations have in relation to reporting
unusual or suspicious transactions, receiving suspicious transaction reports and investigating
money laundering offences. To aid this adaptation key areas of the handbook have been
highlighted for “Country Specific Insertions”.
While the aim of this handbook is to raise the awareness of tax examiners and tax auditors
about the possible implications of transactions or activities related to money laundering and
tax crimes, the handbook is not meant to replace domestic policies and procedures.
This handbook is available on the CTPA website www.oecd.org/ctp/taxcrimes. Versions
in different languages will also be available here.

Introduction
Fighting crime
Traditionally the job of fighting crime has focused on solving crimes. However, since the
1990s, crime fighters have also sought to deter criminals by paying more attention to the
confiscation of proceeds of crime. And more recently, with the introduction of unusual or
suspicious transaction reporting by the regulated sector, often the flow of money or goods
is investigated even before a criminal offence has been detected.
Why criminals need to launder money
A person who commits a crime will initially try to prevent their actions from being
noticed by the tax department, police and/or law enforcement authorities. If the person
is arrested or taxed on the proceeds of crime, they will try to avoid having the criminal
proceeds traced back to their origin and avoid their confiscation.
When criminals want to spend the proceeds of their crime, they face a dilemma: how
to spend or invest large sums of money without evidence of a legitimate source of income
that could draw the attention of tax examiners or auditors. Alternatively, criminals’ ability
to expend cash on the purchase and use of high value goods or investments may bring them
to the attention of law enforcement authorities. The tax department can start a tax audit
and issue a tax reassessment while law enforcement authorities can initiate a criminal
investigation into the origin of the money.
In order to be able to spend money openly, criminals will seek to ensure that there is
no direct link between the proceeds of their crime and the actual illegal activities. They
may also seek to construct a plausible explanation for an apparent legal origin of the money
that they possess. In this way, criminals seek to “launder” their proceeds of crime before
spending or investing it in the legal economy.

Money Laundering
Definition
The Financial Action Task Force (FATF) is an inter-governmental body whose purpose
is the development and promotion of policies to combat money laundering and terrorist
financing. It is the body that sets and monitors international standards for anti-money
laundering regulations. The FATF has defined “money laundering” as the processing of
criminal proceeds to disguise their illegal origin in order to legitimise the ill-gotten gains
of crime.

Why combat money laundering?
Criminals accumulate significant sums of money by committing crimes such as drug
trafficking, human trafficking, theft, investment fraud, extortion, corruption, embezzlement
and tax fraud. Money laundering is a serious threat to the legal economy and affects the
integrity of financial institutions. It also changes the economic power in certain sectors. If
left unchecked, it will corrupt society as a whole. Fighting money laundering serves several
purposes.

The social importance
Crime causes tangible and intangible damage to third parties, individuals and society
as a whole. Money laundering can result in reducing the public’s confidence in certain
professions such as lawyers, accountants and notaries and economic sectors such as real
estate, hospitality and banks and other financial institutions. Investing the proceeds of crime
may also distort competition between businesses and entrepreneurs. Money laundering
allows the criminal to start, continue and expand activities in legitimate sectors of the
economy. It may create a perception that crime pays and may also have a stimulating effect
on our youth starting a criminal career.
To identify tax crimes
Unusual transactions can be an indication of tax crimes in the past and can lead to the
identification of those involved.
To identify other crimes and criminals
Taxing the income of criminals according to tax rules alone will not lead to the
identification of potential money laundering. It will not stop crime from happening or from
being profitable. The detection of unusual transactions may assist in identifying criminals
and their illegal activities. Sharing information with law enforcement authorities can lead
to the start of a criminal investigation.
To locate and confiscate criminal assets
Identifying unusual transactions can provide insight into the flow of money and the
destination of laundered criminal proceeds into assets such as real estate, vehicles, yachts
and bank accounts. This will assist law enforcement authorities in seizing those assets
during a criminal investigation.
Legal context
In the vast majority of countries there is a legal framework for combating money laundering
and it is a separate criminal offence in the penal code. The penal code states which activities
in relation to proceeds of crime are forbidden and lists the relevant crimes covered, known
as predicate offences to money laundering. Predicate offences can be defined as “all offences”
named in the penal code or can be limited to “serious crime offences” or a threshold related
to the penalty of imprisonment or a combination of these approaches.
The legislation may include tax crimes as a predicate offence to money laundering. It
is also possible that tax crimes are not mentioned as a predicate offence. This means that
transactions with money solely derived from a tax crime (e.g. non reported sales) might not
be considered as money laundering offences. This does not mean that the tax administrations
in those countries have no role in combating money laundering. Money derived from crimes
mentioned as a predicate offence could still be identified by tax examiners or auditors and
there may also be tax implications.
It may be appropriate to insert here country specific detail on the legal context.

The money laundering process
The objective of tax fraudsters and of those involved in a wide range of criminal activities
is to disguise the source of money and to convert the “dirty money” and “wash it” into a form
that will be difficult to retrace its origins such as placing the “dirty money” in bank accounts,
real estate, stocks, insurance premiums and other assets, which can be used later without
raising suspicion. Whether the crime is a tax crime or is related to trafficking in narcotics,
illegal sales of weapons, corruption or any of a vast range of criminal activities, the basic
process that money launderers use to turn illicit proceeds into apparently legal monies or
assets is globally accepted as having three stages: placement, layering and integration. These
are the three phases of money laundering. The integration phase may be further divided
into two sub-phases: justification and investment.
Placement
The goal in this stage is to deposit criminal proceeds, generally cash, into a bank account
at home or abroad. For this purpose, cash could be switched into other valuables like trade
goods, diamonds, gold bars or cheques. It could also be exchanged into other currencies,
in larger denominations and/or split up in smaller sums which allow easy transportation
by cash couriers. The cash or other valuables can be transported abroad, away from the
country where the crime was committed, to the country of residence of the criminal or a
specific country where cash can be easily deposited or invested. Transportation can be by
car, plane (passengers or cargo) or by using an underground banking system. For all of these
acts, criminals can use third parties, either individuals or corporations. Money derived from
fraud, like tax fraud or investment fraud, could easily be money held in a bank account and
capable of being exchanged electronically. Not all criminal proceeds are in the form of cash
or even money. Goods from theft can be exchanged for other valuables.
Layering
The goal in this stage is the concealment of the criminal origin of the proceeds. Therefore,
money can be transferred and split frequently between bank accounts, countries, individuals
and/or corporations. Money can also be withdrawn in cash and deposited into bank accounts
with other banks. It is common to use bank accounts in countries with strict banking secrecy
laws and to nominate offshore corporations as the bank account holders.
Integration: Justification
The goal in this stage is to create an apparent legal origin for the criminal proceeds.
This can be done by:
• Doing business with yourself (falsifying sources of income, capital gains and/or
loans);
• Disguising the ownership of assets, and
• Using criminal proceeds in transactions with third parties.
The money launderer creates an apparent legal origin of the money by fabricating
transactions (invoices, bookkeeping and agreements), with the use of false and fabricated
Money Laundering Awareness Handbook for Tax Examiners and Tax Auditors 2009

documents such as invoices, reports, contracts, agreements, deeds as well as written or
spoken statements. Common justification methods used are:
• Fabricating a loan: loan-back or back to back;
• Fabricating a rise in net worth: buying and selling real estate and other items, fabricating
casino winnings, lottery prizes, inheritance, etc.;
• Disguising the ownership of assets and interest in businesses (constructions with
foreign legal entities, e.g. offshore companies or relatives as legal owner);
• Price-manipulating (over- and under-invoicing);
• Manipulating turnover/sales by commingling illicit and legal sources of income.
Integration: Investment
The goal in this final stage is to use criminal proceeds for personal benefit. Cash or
electronic money can be used for:
• Safekeeping: cash on hand;
• Consumption: day to day expenditures, lifestyle, jewellery, vehicles, yachts, art;
• Investing: bank accounts, real estate, stocks, securities, receivables, funding of legal
and illegal business activities.
Criminals may want to display their wealth and wealthy lifestyle by acquiring “badges of
wealth” such as luxury homes, vehicles, boats, jewellery, etc. Criminals will seek to launder
the proceeds from their crimes to pay for these in order to avoid detection by the tax or law
enforcement authorities.
Money laundering trends
The traditional methods of money laundering have centred on the use of cash based
businesses and this remains an important area. However, criminals will continue to seek
out innovative methods to exploit weaknesses in financial systems and to try to keep ahead
of the investigators. Real estate, loans and trade based money laundering are preferred
methods for criminals to launder the proceeds of crime and tax fraud. These are described
later. The use of credit cards issued by offshore banks has increased and can expect criminals
to explore the vulnerabilities of new technology based products such as electronic money
and internet-based trading and gambling.

Role of Tax Examiners and Auditors
Introduction
The role of tax examiners or auditors in checking taxpayers’ books and records for
tax assessments puts them in a unique position to identify not only tax crimes, but also
money laundering and other financial crimes. Auditors can help combat money laundering
by identifying and then reporting unusual or suspicious transactions in accordance with
domestic law and practice. This handbook provides a tool for auditors to detect money
laundering, but the identification of money laundering indicators in a case may also help
auditors to detect past tax evasion.
Raising knowledge and awareness
Tax auditors or tax examiners are often well placed to identify the first signs of possible
money laundering and tax crimes. Generally their education and training allows them to
detect suspicious transactions. While the aim of this handbook is to raise the awareness of
tax examiners and tax auditors about the possible implications of transactions or activities
related to money laundering and tax crimes, the handbook is not meant to replace domestic
policies and procedures. Rather, tax examiners or auditors will carry out their duties in
accordance with the policies and procedures in force in their country.
Tax examiners or auditors must be aware of the need to distinguish between appearance
and reality. It is useful to remember the following distinctions:
Fact: an event or act whose reality has been established;
Assertion: an opinion in the form of a statement or document such as: invoices, loan
agreements, deeds, tax returns;
Assumption: a presumption or a supposition;
Conclusion: a deduction made based on facts or assertions.
Sorting the available information in this manner can assist tax examiners or auditors in
avoiding conclusions based on assertions or assumptions instead of verified facts. The most
important tool for tax examiners or auditors is to bring critical thinking to the forefront:
To evaluate the assertions made;
To question and investigate their own assumptions as a hypothesis;
Money Laundering Awareness Handbook for Tax Examiners and Tax Auditors 2009

To draw conclusions based on their knowledge of the techniques used by money
launderers and tax criminals.
The importance of detecting unusual transactions
The proceeds of a crime may become apparent to tax examiners or auditors. Such
visibility is related to:
Cash movements such as transporting, exchanging, depositing or spending;
The use of known money laundering methods or processes;
The increase in income and/or capital gains;
Unusual possessions (e.g. works of art, expensive vehicles), unusual loan arrangements
and increased prosperity that is not proportionate to legitimate income.
Detection of “dirty” money focuses primarily on unusual transactions that indicate
possible money laundering. ‘Unusual’ means that a transaction differs from the norms of a
certain industry or the habits of an individual, taking into account their background, normal
activities or declared income. Deviation from normal or expected behaviour may indicate
risk. The greater the deviation in behaviour and the more frequent the occurrence of unusual
situations, the greater the risk for money laundering. Subsequent assessment is required.
In general, unusual transactions have certain characteristics, to make it possible to
conceal and to justify the illegal origin of the money, the flow of money, the possession of
the money or assets derived from it:
The fact that the origin of the funds is not clear;
The fact that the identities of the parties are not clear;
The transaction does not fit the person’s background or legal income, and
The fact that there is no economical or logical explanation for the transaction.
To identify unusual transactions, these general characteristics are transformed into
money laundering indicators:
Money laundering indicators for individuals
Tax return examination and pre-audit indicators
Audit indicators
Specific indicators on real estate
Specific indicators on cash
Specific indicators on international trade
Specific indicators on loans
Specific indicators on professional service providers.

The reporting of unusual transactions
The reporting of unusual transactions by tax examiners or auditors will differ within
jurisdictions and the requirement to report will be either mandatory or discretionary. All
tax examiners and auditors should make themselves aware of these requirements so that
