Finland is boosting crypto-asset tax transparency with the CARF MCAA from January 2026 and new DAC8 reporting rules.
Finland’s Ministry of Finance issued Notice No. 74/2025 on 31 December 2025, confirming that the Multilateral Competent Authority Agreement under the Crypto-Asset Reporting Framework (CARF MCAA) took effect in Finland starting today, 1 January 2026.
Under this agreement, Finland will begin exchanging tax-relevant information on crypto-assets in 2027, covering the 2026 reporting year.
The CARF MCAA, along with the CARF itself, is an OECD initiative designed to promote transparency in the rapidly expanding crypto-asset sector by establishing standardised reporting and due diligence rules for tax authorities.
Earlier, on 1 December 2025, Finland officially published Law 1044/2025, enacting EU Directive 2023/2226 (DAC8) to introduce new reporting and due diligence obligations for crypto-asset service providers. DAC8, approved by the European Council in October 2023, builds on the OECD’s CARF and the updated Common Reporting Standard (CRS) to enhance automatic tax information exchange.
