In November 2025, the Hungarian Parliament adopted an act introducing further amendments to the legal framework governing international tax cooperation and transparency.
The new legislation brings Hungarian law into closer alignment with EU and OECD initiatives, in particular the rules on the global minimum tax (Pillar Two) and the expanding system of automatic exchange of information between tax authorities.
As a result, cooperation between the Hungarian tax authority, other EU Member States and certain third countries is reinforced with broader information-sharing mechanisms intended to support the detection of tax avoidance and undisclosed income.
The amendments also address the implementation of the 15% global minimum effective tax rate applicable to multinational enterprise groups with consolidated annual revenues exceeding EUR750 million. The reporting framework has been adjusted to reflect the requirements of the EU Pillar Two Directive and to facilitate the application of any top-up tax through coordinated data submissions.
In addition, stricter transparency and reporting obligations have been introduced in relation to crypto assets, in line with international developments aimed at bringing crypto-related income more clearly within the scope of tax reporting and cross-border information exchange. Affected groups and market participants may wish to review their existing reporting processes and assess whether further compliance steps will be required under the new rules.
