OECD Common Reporting Standard: Family Office Guide
The OECD Common Reporting Standard (CRS) is a multilateral automatic exchange of financial account information framework adopted by over 100 jurisdictions. It requires financial institutions, including certain family office structures, to identify account holders and controlling persons who are tax residents in participating jurisdictions, collect standardised due diligence documentation, and report relevant account data annually to their home tax authority, which then exchanges that data with the account holder's country of tax residence.
Amendments introduced through the OECD's ongoing review process, including the 2023 Crypto-Asset Reporting Framework (CARF) package, materially expanded CRS scope. Key updates tightened due diligence rules for passive non-financial entities (Passive NFEs), broadened the definition of reportable accounts, and strengthened rules around undocumented accounts. Jurisdictions are progressively incorporating these amendments into domestic law, with implementation timelines varying. Family offices structured as investment entities, particularly those that are professionally managed, are typically classified as Reporting Financial Institutions and carry full CRS obligations, while those managed exclusively by family principals may qualify as non-reporting NFEs, though this distinction requires careful, jurisdiction-specific legal analysis.
Who is affected
- Family offices structured as investment entities managed by a third-party financial institution, triggering Reporting Financial Institution status
- Family members and beneficial owners who are tax residents in CRS-participating jurisdictions and hold accounts at reporting institutions globally
- Family trusts, foundations, and holding vehicles classified as Passive NFEs, requiring disclosure of controlling persons to reporting institutions
Key changes
- Passive NFE controlling person rules tightened: broader categories of individuals must be identified and reported, increasing look-through obligations on family holding structures
- 2023 amendments aligned CRS more closely with CARF, adding crypto-asset adjacent guidance and reinforcing that certain electronic money products fall within reporting scope
- Enhanced due diligence requirements for high-value accounts and strengthened penalties in many adopting jurisdictions for non-compliance or undocumented account holders
Recommended action
Engage qualified legal counsel in each jurisdiction where the family office or its entities are domiciled to confirm current classification, Reporting Financial Institution vs. Non-Reporting NFE, under the latest domestic CRS implementing legislation. Immediately audit all self-certification forms (W-8/CRS equivalents) held for account holders and controlling persons to ensure they reflect current tax residency and meet updated due diligence standards before the next annual reporting deadline.
