CRS, CARF, DAC7, DAC8 & FATCA Reporting Regulatory Compliance

Tax transparency reporting refers to the regulatory obligation for financial institutions to identify, classify, and report account holder tax residency information to tax authorities. It encompasses frameworks including CRS, DAC8, CARF, DAC7, and FATCA — each targeting specific asset classes, institution types, and reporting jurisdictions. The scope has expanded dramatically since 2023, with crypto-assets, e-money, and platform economies now in scope.

TaxDo supports five tax transparency frameworks through one unified engine: CRS 2.0 (OECD Common Reporting Standard), DAC8 (EU crypto-asset reporting), CARF (Crypto-Asset Reporting Framework), DAC7 (EU platform economy reporting), and FATCA (US Foreign Account Tax Compliance Act). One self-certification process, one identity verification layer, one reporting engine — five framework outputs.

The Reasonableness Test cross-references self-declared information against multiple independent signals from authoritative, documentary, and institutional sources. It determines whether an account holder's self-certification can be accepted as reliable, or whether discrepancies require further due diligence and curing. This is the step where surface-level compliance separates from forensic compliance.

Intelligent curing resolves discrepancies between self-declared information and independent signals through multiple automated resolution methods — auto-correction from authoritative sources, targeted account holder prompts, document requests, and entity re-classification. Over 95% of discrepancies resolve without human intervention. The remaining cases are escalated with full context so compliance officers act on information, not guesswork.

Yes — but only if the platform is built as an operating system, not a point solution. Each framework has different classification rules, indicia requirements, and reporting schemas. TaxDo's shared identity infrastructure handles the commonalities (TIN validation, entity classification, self-certification), while framework-specific modules handle the differences (regime-specific indicia, jurisdiction-specific XML, framework-specific blocking and withholding rules).

Day-1 readiness means due diligence begins at the moment of account opening — not retroactively. The intelligent self-certification interview collects, validates, and classifies account holder information in real time during onboarding. Every new account enters the compliance pipeline fully documented from its first day. No remediation campaigns. No retrospective data collection.

Under DAC8, a crypto-asset service provider must stop a crypto-asset user from making reportable transactions if the user has not provided a valid self-certification after two reminders and at least 60 days from the first request. TaxDo tracks certification status against regulatory timelines, triggers escalation workflows before deadlines, and provides the audit trail needed to enforce or document blocking decisions. The platform ensures CASPs can demonstrate to regulators that they took appropriate action.

Forensic due diligence goes beyond checkbox compliance. It applies multi-category indicia detection across TIN signals, address and residency indicators, entity classification markers, controlling person cascades, and behavioural patterns — identifying tax residency obligations that surface-level checks miss. The distinction is critical: checkbox compliance catches what the form asks; forensic due diligence catches what the regulation requires.

Banks, custodians, insurers, crypto exchanges and CASPs, neo-banks, e-money institutions, fund managers, investment entities, and digital platforms and marketplaces. Each faces different framework obligations depending on licence type, asset classes held, and operating jurisdictions. CRS 2.0 expanded scope means previously excluded institution types (e-money issuers, certain investment advisors) are now reporting entities.
