Remediation of Tax Forms: Turning a Compliance Challenge into a Strategic Advantage

Remediation of Tax Forms: Turning a Compliance Challenge into a Strategic Advantage

Financial institutions should have an annual process to identify gaps in their account’s tax certification data, and have a process to request new or updated documentation already. Remediation stops being a one-off fix and becomes a strategic opportunity to strengthen compliance, improve data quality, and future-proof tax operations. With CRS 2.0 on the horizon, remediation has never been more topical, or more critical.

 

Why Remediation Matters Now

Identifying accounts for remediation is always important, but CRS 2.0 brings with it heightened regulatory expectations, especially around remediation of legacy tax forms. Firms that have historically relied on manual processes now face a dual challenge:

• Correcting errors and gaps in existing records
• Ensuring ongoing compliance with stricter, evolving standards

The new data requirements are not just for new accounts but are applicable to all accounts. The OECD announced these changes in 2023 and did not require these changes to become a requirement until each participating jurisdiction updated their tax laws by the end of 2025. Failure to remediate efficiently in time to complete reporting of 2026 transactions in 2027 reporting season doesn’t just increase operational burden, it exposes institutions to risk and reputational damage.

Best Practices to Perform Remediation

1. Conduct a Comprehensive Data Impact Assessment

• Identify gaps in current account data vs. new CRS 2.0 requirements.
• Flag accounts missing existing required data fields but specifically:
  • Valid self-certifications
  • Tax Identification Numbers (TINs)
  • Jurisdictional information
  • Controlling Person details for Passive NFEs
• Assess exposure to new account types previously out of scope of CRS reporting but may now be part of new CARF requirements (e.g., e-money, CBDCs, crypto derivatives).

2. Data Validation & Cleansing

• Perform data analysis to:
  • Detect inconsistencies in entity classification (e.g., FFI vs. NFFE)
  • Validate TIN formats and jurisdictional rules
  • Cross-check against OECD and jurisdiction specific schemas
  • Use AI-powered RegTech tools if internal resources are limited
• Recommended platforms:
  • TAINA: Jurisdiction-specific validation
  • Evalogical Engine: Schema compliance automation

3. Strengthen Self-Certification Management

• Ensure all accounts have valid, reasonable self-certifications on file.
• Implement workflows to:
  • Re-request expired or invalid certifications
  • Validate Controlling Persons for Passive NFEs
  • Align with AML/KYC procedures under EU directives

4. Upgrade XML Reporting Infrastructure

Prepare for OECD CRS XML Schema v2.0 updates which will be required to report the new data fields starting in 2027. Whether building an internal solution, or leveraging existing vendor solutions, it is easier to remain compliant if the financial institution can automate schema validation, cross-field consistency checks, and error correction suggestions.

5. Enhance Governance & Audit Readiness

• Establish a CRS governance framework including process and procedures for how to maintain compliance:
  • Assign accountability for remediation
  • Maintain audit trails of data changes
  • Conduct periodic desktop reviews and mock audits
• Train staff on:
  • New CRS 2.0 requirements
  • Due diligence procedures
  • Data privacy and GDPR compliance

6. Monitor Regulatory Updates

• Whether a financial institution has an internal team, uses vendor services, or leverages a tax consultant, it is critical to stay informed on:
  • OECD peer review outcomes
  • Jurisdiction-specific enforcement trends
  • FATCA/CRS FAQs and schema updates
