The degree of channeling determines to a large extent the extent to which the government’s policy objectives, namely the prevention of crime and fraud, the prevention of gambling addiction and the protection of consumers, is achieved. The higher the channelisation, the better the Netherlands scores against its objectives.

Gambling tax

This is a direct tax on games of chance, which is levied by the government. Gambling tax is a tax that participants of games of chance or organisers of games of chance must pay on the winnings from the games of chance. The tax is levied on the basis of the Dutch Gaming and Betting Tax Act (Wet KSB) and Chapter VIIa of the Dutch Tax Act BES. Since 1 January 2018, the Netherlands has a gambling tax of 30.1 percent on the value of the prize that can be won. This seems unambiguous, but it is not. In practice, the value of the prize is determined in various ways. In addition, there are exemptions. For example, Holland Casino pays 30.1 percent gambling tax on the gross game result (stake minus the prizes). The lotteries also have an exemption from gambling tax for prizes up to € 449. A very significant portion of the lottery prizes fall under this category, which means that the lotteries effectively only pay around 10 percent gambling tax.

ISP blocking

Blocking Internet Service Providers (ISP’s). ISP blocking is regularly used to prevent consumers from participating in online games of chance by blocking certain internet addresses. The effectiveness of this measure is limited, because such blockages are easy to avoid.


This is the abbreviation for the Netherlands Gaming Authority ‘Kansspelautoriteit’, the Dutch regulator of the games of chance market. The Ksa is exclusively authorised to issue licenses for games of chance, to supervise licensees, to combat illegal games of chance and to protect consumers against gambling addiction.


This is the abbreviation for Know Your Customer. This term describes all measures that an online games of chance provider takes from the perspective of risk management and compliance, in order to obtain and check relevant information from the customer with whom he enters into a business relationship. An example of this is requesting a scan of an identification document, in order to verify the identity of the customer.


This stands for Know Your Transaction and describes the process and the measures that an online games of chance provider takes from risk management and compliance, in order to obtain and check relevant information about the financial transaction to be processed.

Match fixing

This is the illegal manipulation of the outcome of sports matches by improperly determining the course or outcome of a competition or specific events within it (such as individual matches or races, or events during matches). This is done, among other things, by offering athletes or club representatives a financial reward if they manipulate the outcome of a match or competition.

Policy objectives

These are the Dutch government’s gambling policy objectives, being: the prevention of crime and fraud, the prevention of gambling addiction and the protection of consumers.

Prevention measures

This is an important part of the prevention policy of online games of chance providers. Examples of measures that can be taken:

  • A self-test that provides the customer with insight into their own gaming behaviour;
  • Deposit limits that can be imposed in order to control gaming behaviour;
  • Inserting a cooling-off period when the gaming behaviour requires it;
  • (Self) exclusion of players who exhibit structurally problematic gaming behaviour.
