Parliament approves protocol updating the 1996 tax treaty to meet OECD standards.

The Luxembourg parliament ratified a protocol updating the 1996 income and capital tax treaty with Vietnam on 2 December 2025.

The Chamber of Deputies approved the protocol on 20 November 2025, following earlier approval by the Council of State on 11 July 2025.

Signed on 4 May 2023, the protocol updates the treaty to align with OECD standards for information exchange. With a clear parliamentary majority, the Council of State waived the need for a second vote.

The updated treaty will enter into force upon Luxembourg and Vietnam exchanging ratification documents and will apply from 1 January of the following year.
