Federal Council approved amendments to its AEOI framework, with updated CRS rules set to take effect in 2026 while CARF implementation was delayed until at least 2027.
The Swiss Federal Council has approved amendments to the Ordinance on the International Automatic Exchange of Information in Tax Matters (AEOI Ordinance), confirming that the revised rules will take effect on 1 January 2026 alongside the amended Federal Act on the International Automatic Exchange of Information in Tax Matters (AEOIA).
This announcement was made on Bern, 26 November 2025.
In the 2025 autumn session, both the National Council and the Council of States backed the OECD-adopted extension of the international automatic exchange of information in tax matters (AEOI). The update includes changes to the common standard on reporting and due diligence for financial account information (CRS) and the expansion of the new Crypto-Asset Reporting Framework (CARF).
The amended AEOI Ordinance introduces reporting, due diligence and registration duties for crypto service providers and defines their nexus to Switzerland.
It also provides that the CRS will directly apply to associations, foundations and their accounts, with exclusions available where specific conditions—set out in the revised ordinance—are met. Transitional provisions are included to support implementation of the amended CRS and CARF.
On 3 November 2025, the National Council’s Economic Affairs and Taxation Committee (EATC) suspended its examination of partner states with which Switzerland plans to exchange data under the CARF. As a result, while the CARF will be enshrined in law from January 2026, it will not be implemented on 1 January 2026 as originally planned. Implementation is now expected in 2027 at the earliest. The Federal Council has therefore confirmed that provisions on crypto-assets in the AEOIA and AEOI Ordinance will not apply in 2026.
