The First CRS 2.0 Season

About This Guide

The First CRS 2.0 Season: A Readiness Guide to Reporting Season 2027 explores the regulatory changes and operational challenges facing financial institutions as they prepare for the 2026 data year and the first reporting season under CRS 2.0 and CARF.

The guide examines why Reporting Season 2027 will be different, with amended CRS requirements introducing new data points, expanded product scope and tighter due diligence obligations. It also considers how these changes coincide with existing US year-end reporting requirements, including 1099 and 1042-S, creating additional pressure on tax operations, compliance and reporting teams.

It explores the risks that can emerge when documentation, data quality and information sharing break down across onboarding, fund administration and withholding processes. From missing self-certifications and incomplete account information to multi-tier structures and year-end reconciliation, the guide highlights why reporting challenges often begin long before a return is submitted.

The guide also covers key reporting deadlines, the transition from the IRS FIRE system to IRIS, the importance of maintaining audit-ready evidence and the operational foundations needed for a successful reporting season. It includes a practical, timeline-based readiness checklist and a self-assessment to help organisations identify potential gaps and prioritise action ahead of 2027.

Drawing on TAINA's industry experience, the guide outlines how financial institutions can move beyond seasonal reporting preparation towards continuous validation, change-in-circumstance monitoring and year-round reporting readiness.
