The international tax transparency standard OECD CARF will be officially implemented in 2026, and the number of Web3 foundations in the Cayman Islands has surged by 70%.

On December 3, according to Cointelegraph, the number of foundation company registrations in the Cayman Islands surged by 70% year-over-year, exceeding 1,300 by the end of 2024, with more than 400 new registrations in the first five months of 2025. Cayman foundations are becoming the mainstream legal wrapper for DAOs, used for treasury custody, holding IP, and handling compliance matters. At least 17 of these foundations have treasuries exceeding $100 million. Notably, the international tax transparency standard OECD CARF reporting framework will be officially implemented in 2026. The OECD CARF aims to address tax evasion related to crypto asset transactions through standardized automatic information exchange mechanisms. The Cayman Islands will require crypto service providers, such as exchanges and custodians, to conduct due diligence and reporting, but protocol treasuries and passive foundations that only hold assets are expected to be outside the scope of mandatory reporting.
