Parliament today approved, in general, rules on the exchange of tax information regarding the minimum corporate income tax (CIT) and sanctions for crypto asset service providers that fail to report data to the tax authority.
📰 Source: Lusa - April 10, 2026
The initiative received votes in favour from PSD, CDS-PP, PS, Chega, Livre, BE, PAN, and JPP. IL and PCP abstained, with no votes against. The Government's proposal will now proceed to committee-stage discussion at the Budget, Finance and Public Administration Committee.
Fines for crypto asset service providers
The legislation provides that crypto asset service providers will face fines if they fail to submit to the Portuguese Tax Authority (AT), by February each year, information on transactions carried out by their clients during the previous year, as well as data on financial accounts.
Automatic exchange of tax information
The legislative initiative regulates a series of automatic information exchange rules that will allow the AT to access information on financial accounts - not only on crypto asset transactions, but also on bank accounts and other financial accounts located in other countries.
The legislation transposes into Portuguese law rules set out in two European directives, from October 2023 and April 2025, which amend the directive in force on administrative cooperation in the field of taxation. The rules aim to prevent tax evasion with digital assets and the diversion of corporate profits to tax havens.
Global minimum CIT of 15%
💡 Multinationals with consolidated revenues of at least €750 million must pay a minimum profit tax of 15% worldwide.
Another part of the legislation concerns the payment of the Global Minimum Tax (minimum CIT of 15%) by large multinational companies. The proposed reporting rules follow the OECD model rules to implement the international tax agreement of October 2021.
Under the agreement reached between more than 130 jurisdictions, multinationals with consolidated revenues of at least €750 million must pay a minimum profit tax of 15% worldwide. The tax authorities of the multinationals' headquarters may apply a top-up tax to reach that minimum level.
Government's explanatory memorandum
"The initiative responds to new challenges arising from the growing use of alternative means of payment and investment, which pose new risks of tax evasion, contributing to strengthening the integrity of the tax system and ensuring fairer taxation."
The proposal amends Law No. 41/2024, of November 8, passed by parliament to implement global minimum CIT rules, transposing the mechanisms for automatic exchange of information on the top-up tax between Portuguese and foreign tax administrations.
📌 Editor's note: This legislation reinforces the need for companies with crypto asset operations to be properly prepared to comply with the new tax reporting obligations. If you have questions about how these rules affect your business, contact us.
