The Reporting Season Domino Effect

How small data gaps become big reporting problems 

Reporting season used to mean one thing: a deadline. Get the forms filed, get the numbers right, and move on until next year. That is no longer an accurate picture of what reporting season actually is for most financial institutions. 

The rules have changed. But the real difference is the growing recognition that small gaps in data collection, maintenance, and governance can affect reporting outcomes months later. 

This Season Is Different 

This reporting season arrives against a backdrop of significant change. CRS 2.0 introduces new reporting requirements and additional data points within reporting schemas, while CARF brings an entirely new reporting regime for crypto-assets. Jurisdiction-specific implementation is also creating additional complexity. For example, the UK has adopted domestic CARF reporting, an obligation not found under CRS. 

These changes are increasing the volume, complexity, and scrutiny of reporting data. Organisations are not simply being asked to generate reports. They are being asked to demonstrate that the underlying information is complete, accurate, and capable of supporting evolving compliance obligations. 

The result is that questions around CRS 2.0 readiness are now being raised publicly across the industry. Fund administrators are being asked during conferences whether they are prepared for the new requirements, highlighting a broader shift in focus. The conversation is no longer just about filing reports. Those responsible for reporting are under growing pressure to demonstrate that the data, controls, and governance supporting their filings are fit for purpose. 

The Domino Effect  

Reporting issues rarely originate in the reporting process itself. A small issue upstream can easily become a much larger problem downstream. For example: 

• A change in tax residency that is not passed to the right team.  

• A controlling person update that is captured in one system but not another.  

• A self-certification that is accepted but never reflected in downstream reporting data.  

Each issue may seem minor in isolation, but reporting season has a way of exposing every weakness in the chain. 

By the time reporting files are being prepared, those small gaps can result in accounts being reported to the wrong jurisdiction, reported to multiple jurisdictions incorrectly, or omitted altogether. The reporting error is often only the final symptom of a problem that began months earlier. 

The consequences extend beyond reporting accuracy. Under-reporting may lead to regulatory scrutiny, follow-up enquiries, and potential penalties for non-compliance. Over-reporting can also raise regulatory concerns, create data protection risks if personal information is disclosed to tax authorities that should not have received it, and damage client confidence when reporting errors come to light. What starts as a small data issue can quickly become a broader governance problem. 

And the real cost is not necessarily the correction of an individual report or even a fine for non-compliance. It is the uncertainty that follows. Once a reporting issue is identified, institutions need to determine whether the problem is isolated or whether similar issues exist elsewhere in the population. If one account was reported incorrectly, how many others were affected by the same process failure? That question often triggers large-scale remediation exercises, additional client outreach, and significant manual effort to rebuild confidence in the data. 

The lesson is simple: reporting season actually starts at onboarding. It starts when data is first collected and continues throughout the lifecycle of the account as information is maintained, validated, and updated. By the time the first XML file is being prepared, the dominoes have already either been lined up correctly or started falling. 

The Problem Is Often Upstream of Reporting Itself 

A financial institution may receive the right information, but that does not guarantee the right reporting outcome. Data moves through multiple teams, systems, and service providers before reporting season arrives. If information is not updated consistently throughout that process, reporting errors become almost inevitable. 

As organisations prepare for CRS 2.0 and CARF, the focus should not just be on reporting readiness. It should be on data readiness. The ability to produce an XML file matters, but the quality of the file, and your ultimate compliance, will always depend on the quality of the data behind it. 

Preventing the Dominoes From Falling 

The challenge is not simply producing an XML file at year-end. It is ensuring that the underlying data remains accurate, complete, and consistent from onboarding through to reporting. Changes in tax residency, controlling person information, and other key data points must be captured, validated, and reflected across the operating model. 

Organisations that wait until reporting season to identify issues often find themselves reacting to problems that originated months earlier. Those that focus on data quality and governance throughout the year are better positioned to meet their reporting obligations with confidence, ensuring that small issues are addressed before they have the opportunity to cascade through the reporting process and beyond.
