Hungary’s President has signed the Law No. LXXIII of 2025 on the Multilateral Competent Authority Agreement on Automatic Exchange of Information Pursuant to Crypto-Asset Reporting Framework (CARF MCAA), and its list of participating jurisdictions, which was published in the Official Gazette as of No. 127 of 31 October 2025.
The agreement will take effect once the entry date is announced in the Official Gazette at a later date.
The international standards developed by the OECD provide for transparency and exchange of information on request (EOIR) and for automatic exchange of financial account information (AEOI).
The EOIR standard requires that information that is “foreseeably relevant” for tax purposes, such as information on the identity of the legal and beneficial owners of assets, companies and accounts, be available and accessible to tax authorities that can then exchange this information with tax authorities in other jurisdictions, on the basis of an international agreement.
The AEOI standard, covering the Common Reporting Standard and the Crypto-Asset Reporting Framework, requires the annual exchange of a predefined set of information on financial accounts and crypto-asset transactions between tax authorities. Under the AEOI Standard, participating jurisdictions collect information from their financial institutions and crypto-asset service providers on the basis of a common set of due diligence and reporting requirements and automatically exchange such information in a predefined format with the country of residence of the account holders and crypto-asset users.
Earlier, the National Assembly approved Bill T/12489 ratifying the Multilateral Competent Authority Agreement on the Automatic Exchange of Information under the Crypto-Asset Reporting Framework (CARF MCAA), which Hungary signed on 26 November 2024.
