FATCA and CRS have matured into established tax transparency regimes, creating an environment where regulators expect consistent accuracy, robust controls, and strong data governance.
According to Scott Nice of Label, the period when authorities tolerated implementation gaps has long passed, and institutions now operate under far closer scrutiny than in the early years of these frameworks.
One of the most significant lessons learned under FATCA and CRS is that misreporting can never be dismissed as an administrative oversight. Financial institutions discovered, often through painful experience, that errors trigger regulatory attention, lead to financial penalties, and result in extensive remediation work that draws heavily on internal resources.
In many countries, these issues have also moved into public view, turning compliance failures into reputational liabilities that spread far beyond the direct relationship between firms and regulators.
Customers are frequently pulled into the consequences as well. When data is inconsistent, incomplete, or incorrect, clients may find themselves subject to enquiries, audits, and long-running tax authority investigations. From the customer’s perspective, the institution is responsible for the failure, regardless of where the legal responsibility lies. This loss of trust is particularly damaging for firms working with high-value or institutional clients, where confidence in compliance processes is fundamental to the relationship.
Timing failures represent another lesson that FATCA and CRS made clear. These regimes require firms to identify and address changes in customer circumstances as they happen. However, many organisations continue to rely on end-of-year reviews and retrospective data clean-ups. While widespread, this practice can itself constitute a compliance breach, as it undermines the expectation of timely and ongoing accuracy.
This reactive model creates a cycle of business-as-usual remediation that has become embedded in many compliance processes. Each year, teams chase missing information, resolve contradictions, and reclassify customers, often the same ones repeatedly. The result is not reduced risk but increased exposure. Data quality continues to erode, customers become frustrated, and regulatory vulnerabilities escalate.
CARF is unlikely to tolerate these legacy approaches. Unlike FATCA and CRS, CARF sits within a crypto-asset environment that is faster-moving, decentralised, and structurally more fragmented. Customer behaviour shifts rapidly, data sources vary widely, and historical controls lack the maturity found in traditional financial systems.
For these reasons, CARF cannot be treated as an annual reporting exercise. It requires a continuous, proactive compliance model that incorporates governance, due diligence, data quality, and ongoing monitoring as everyday capabilities. Firms that rely on retrospective clean-ups or outdated control frameworks will face higher risks than under previous regimes.
Ultimately, the success or failure of CARF will not hinge on regulatory ambiguity. The rules are not the issue. The determining factor will be whether institutions apply the lessons learned under FATCA and CRS—or whether they fall back into the patterns that caused problems in the past. The industry now faces a clear question: will it evolve, or repeat its most costly mistakes?
