Responding to a mandate from G20 leaders to reinforce action against tax avoidance and evasion and inject greater trust and fairness into the international tax system, the OECD has unveiled today a new single global standard for the automatic exchange of information between tax authorities worldwide.

Developed by the OECD together with G20 countries, the standard calls on jurisdictions to obtain information from their financial institutions and exchange that information automatically with other jurisdictions on an annual basis. It sets out the financial account information to be exchanged, the financial institutions that need to report, the different types of accounts and taxpayers covered, as well as common due diligence procedures to be followed by financial institutions.

The OECD will formally present the standard for the endorsement of G20 finance ministers during a 22-23 February meeting in Sydney, Australia. The G20 invited the OECD to develop a global standard on automatic exchange of information in 2013, and remains the driving force behind the move toward greater tax transparency worldwide.

Presenting the new standard, OECD Secretary-General Angel Gurría said: "This is a real game changer. Globalisation of the world's financial system has made it increasingly simple for people to make, hold and manage investments outside their country of residence. This new standard on automatic exchange of information will ramp up international tax co-operation, putting governments back on a more even footing as they seek to protect the integrity of their tax systems and fight tax evasion."

The new standard draws extensively on previous OECD work on the automatic exchange of information. It incorporates progress made in this area within the European Union and ongoing efforts to reinforce global anti-money laundering standards. It also recognises the catalytic role that implementation of the US Foreign Account Tax Compliance Act (FATCA) has played in the G20 move towards automatic exchange of information in a multilateral context.

More than 40 countries have committed to early adoption of the standard. The Global Forum on Transparency and Exchange of Information for Tax Purposes, hosted by the OECD, brings together 121 jurisdictions worldwide. It has been mandated by the G20 to monitor and review implementation of the standard.

The OECD is expected to deliver a detailed Commentary on the new standard, as well as technical solutions to implement the actual information exchanges, during a meeting of G20 finance ministers in September 2014.
