Switzerland has scheduled a referendum deadline of 10 July 2025 for the proposed protocol amending the 1971 income and capital tax treaty with Germany.

Earlier, the Swiss parliament granted final approval to the amending protocol to the 1971 income and capital tax treaty with Germany on 21 March 2025.

The protocol complies with BEPS standards and introduces additional provisions to clarify how national minimum taxation rules apply under the Pillar Two GloBE Rules.

The protocol will come into effect upon the exchange of ratification instruments and will generally be applicable from 1 January of the year after it takes effect.
