Automatic Exchange of Information agreements are made between many countries. These agreements allow the exchange of information between tax authorities of different countries about financial accounts and investments to help stop tax evasion.


Financial institutions, for example, banks, building societies, insurance companies and investment companies, will provide information on non-residents with financial accounts and investments to the tax authorities in each country.


Current AEOI regimes include:

  • United States Foreign Account Tax Compliance Act (FATCA)
  • Common Reporting Standard (CRS)
  • UK Crown Dependencies and Overseas Territories (CDOT)
  • EU Directive on Administrative Co-operation
