Global Daily Tax News, Switzerland To Expand AEOI To Eight More States, (Aug 15, 2025)

The Swiss Federal Council has launched a consultation on expanding the automatic exchange of financial account information to a further eight territories.

The required amendments would enter into force on January 1, 2027, enabling the first automatic exchanges of information (AEOI) to begin in 2028 with Armenia, Cameroon, Mongolia, Papua New Guinea, Paraguay, Rwanda, Senegal, and Tunisia.

The consultation is being undertaken as part of the current procedure for expanding the automatic exchange of information, which requires parliament's approval. However, an amendment to the Federal Act on the International Automatic Exchange of Information in Tax Matters (AIAG), currently being debated by parliament, would instead assign authority to the Federal Council.

Subject to the amendment's approval and entry into force on January 1, 2026, the Federal Council will be empowered to expand the exchange of information to these additional states without requiring parliamentary approval.

Should the amendment fail to be adopted, the proposal to expand tax information exchange to these states will be considered by parliament in fall/winter 2026.

The consultation is to run until November 14, 2025.
