The Liechtenstein policy of international cooperation in the prosecution of tax offenses is executed within the scope of its own tax legislation  and the associated powers of the Liechtenstein authorities.

Important steps in the international cooperation in tax matters so far include:

• 2002 MLAT (Mutual Legal Assistance Treaty) Liechtenstein-USA: mutual legal assistance on the basis of an expanded definition of tax fraud
• 2005 Savings Tax Agreement: Liechtenstein incorporates the EU Savings Tax Directive, levies a withholding tax on interest income and transfers a significant share thereof to the European domiciles of Liechtenstein bank clients. Within the scope of the Agreement, Liechtenstein is required to grant administrative assistance upon request in the case of tax fraud and similar offenses.
• As part of implementation of the 2nd Money Laundering Directive, the fiscal exemption is relaxed. Serious cases of value added tax fraud and certain qualified customs offenses have been subject to legal assistance since July 2007.
• 2008 signing of the protocols for Liechtenstein's association with Schengen: from entry into force of Schengen for Liechtenstein (expected the end of 2009), Liechtenstein will grant comprehensive legal assistance in cases of tax fraud.
• 2008 signing of a Tax Information Exchange Agreement (TIEA) with the United States: under the provisions of the TIEA Liechtenstein grants administrative assistance on request in fraudulent cases of tax evasion under US law.

Within the framework of the EU Anti-Fraud Agreement currently under negotiation, Liechtenstein has also made the offer to grant mutual legal and administrative assistance in indirect and direct tax matters using an expanded definition of tax fraud and to solve the remaining questions of cooperation on the prosecution of tax evasion as part of double taxation agreements to be concluded on a bilateral basis.
