YZi Labs backs FinTax as CARF pushes exchanges into long-term tax compliance work
FinTax, a crypto tax and accounting service provider, said on Aug. 27, 2026 that it had closed a seed round led by EASY Residency S4, an entity under YZi Labs, at a post-money valuation of $40 million. The deal comes as the OECD’s Crypto-Asset Reporting Framework, or CARF, moves from preparation to execution in key markets. The U.K. began implementing related rules in January 2026, while the European Union started applying DAC8 rules aligned with CARF over the same period. The report argues that the real burden for exchanges is not limited to filing reports. Platforms must identify reportable users, collect self-certifications, verify tax residency data against existing KYC records, and complete due diligence on pre-existing users within the applicable timeline. For the first jurisdictions, that deadline is Dec. 31, 2026. It also highlights the operational and engineering load behind CARF. Spot crypto-to-crypto trades may need to be split into acquisition and disposal legs, transfers must be categorized, and internal data from KYC, matching engines, wallets, payments, staking, and lending systems must be mapped into OECD CARF XML structures. The piece says this turns compliance into a long-lived data pipeline that requires legal interpretation, systems integration, and ongoing tracking of local reporting rules.
