Executives and high-net-worth individuals holding cross-border assets face a rapidly changing compliance landscape. A wave of international fiscal and reporting reforms, from the OECD’s expanded Common Reporting Standard and Crypto-Asset Reporting Framework to EU directives and U.S. beneficial‑ownership rules, is increasing transparency, widening the scope of reportable instruments, and raising the stakes of structuring choices.

This article summarises the reforms most likely to affect cross-border wealth and property as of 11 June 2026 and sets out practical, legally grounded steps executives can take to preserve value, reduce regulatory risk and remain audit‑ready while respecting emerging international obligations.

Understand evolving international reporting regimes

Recent OECD and EU initiatives have materially broadened automatic information exchange and reporting obligations. The OECD’s amendments to the Common Reporting Standard (CRS) and the new Crypto‑Asset Reporting Framework (CARF) introduce reporting of a wider set of digital and tokenised assets and provide XML schemas and technical guidance for exchange among tax administrations.

In parallel, the European Union’s DAC8 (effective 1 January 2026) specifically extends mandatory reporting to crypto‑asset service providers and brings those reports into the EU automatic exchange network; Member States are transposing DAC8 into national law with retroactive effect for calendar year 2026 reporting.

Large multinational groups must also monitor implementation of the OECD’s Pillar Two (GloBE) rules and related administrative guidance, which affect effective tax rates and may interact with domestic minimum top‑up taxes; administrative packages issued by the Inclusive Framework and national enactments continue to evolve through 2025,2026.

Reassess ownership and entity design in light of UBO and BOI rules

Transparency regimes have multiplied: EU AML reforms (AMLD6) harmonise access to Ultimate Beneficial Owner (UBO) registers on a “legitimate‑interest” basis while national public access models continue to diverge; at the same time, the U.S. Corporate Transparency Act and FinCEN’s BOI framework create secure registries accessible to authorised users. Executives must map where their entities fall within these differing access rules.

Practical consequence: ownership chains using layered entities, trusts or foundations are now more likely to be reconstructible by tax and law‑enforcement authorities. Where national rules require centralised beneficial‑ownership filings or permit legitimate‑interest access, the mere legal form will not guarantee confidentiality.

Action for executives includes: (i) conducting a full ownership and control inventory across jurisdictions; (ii) updating entity purpose and substance documentation; and (iii) where appropriate, simplifying structures to reduce exposure to disclosure mismatches and to make governance records defensible in audits or litigation.

Review trusts, foundations and private wealth vehicles for reporting exposure

Trusts, private foundations and similar arrangements are a particular focus of reporting reforms and AML scrutiny. OECD‑aligned standards and national AML rules increasingly treat arrangements that control or benefit from assets as reportable when certain thresholds are met, and reporting regimes for digital assets add further complexity.

Executives should review trust deeds, foundation statutes and agency agreements to ensure that appointed trustees and service providers can satisfy enhanced due diligence and reporting requests and to confirm that fiduciary documentation evidences economic substance and the legitimate purpose of the arrangement.

Where preserving confidentiality is a genuine business need, legal options remain, including lawful use of nominee arrangements (carefully documented), contractual confidentiality protections, and selection of jurisdictions with robust legal safeguards, but these must be evaluated against disclosure obligations and anti‑avoidance rules. Engage counsel to test any confidentiality solution against current UBO/BOI and CRS/CARF obligations.

Strengthen data governance and reporting readiness

The quality of client and counterparty data is now central to compliance. DAC8/CARF/CRS and national reporting formats (XML schemas, IT user guides) require platforms, custodians and advisers to capture standardized identity data, transaction details and wallet‑linking information. Organisations that fail to collect validated identifiers and supporting documentation risk material reporting errors and penalties.

Boards and executives should mandate an enterprise remediation programme: a data inventory, gap analysis against the new templates and schemas, a prioritized remediation roadmap, and investment in secure reporting pipelines and encryption for exchanges with tax authorities.

Consider contracting specialised data‑processing and tax‑technology providers with experience implementing CARF/CRS XML standards, but retain legal control over disclosures and conduct regular independent assurance reviews of reporting accuracy.

Align substance, transfer pricing and tax policy with global minimum tax risks

Pillar Two (GloBE) and related domestic measures change the calculus for low‑tax jurisdictions and certain intercompany arrangements: effective tax rates, deferred tax profiles and intercompany financing must be re‑assessed to avoid unintended top‑up taxes or compliance burdens. Executives controlling business groups with cross‑border holdings should prioritise a coordinated response between tax, treasury and legal functions.

Substance remains the most resilient commercial defence. Actions include strengthening local management and decision‑making, documenting economic activity, formalising board minutes and implementing arm’s‑length treasury and licensing policies that align with both local law and Pillar Two administrative guidance.

Where restructuring is contemplated, model and document the fiscal impact across all relevant jurisdictions, restructuring to avoid a top‑up tax or to eliminate double taxation requires careful planning and, often, advance engagement with tax authorities or rulings.

Adopt proactive compliance and disclosure strategies

Voluntary disclosure programmes, pre‑filing agreements and cooperative compliance arrangements with tax authorities can materially reduce the cost and uncertainty of resolving historic or evolving reporting gaps. Many jurisdictions now operate taxpayer‑assistance channels for implementing CRS/CARF and Pillar Two reporting; informed, early engagement is advisable.

Executives must weigh the costs and benefits of voluntary remediation against the risks of enforced discovery, penalties and reputational harm. Where issues are systemic (for example, platform‑wide crypto reporting deficiencies) consider a centralised remediation and disclosure plan coordinated with external auditors and counsel.

Maintain contemporaneous documentation of decisions, remediation steps and communications with authorities; strong process records are frequently decisive in audit and litigation contexts.

Prepare for audits, information requests and cross‑border enforcement

Cross‑border information exchange is faster and richer than before; tax administrations routinely use exchanged data to open enquiries. Executives should assume that discrepancies discovered in one jurisdiction will surface elsewhere. Establish a single‑point team, combining tax, legal, compliance and external advisers, to triage incoming enquiries and to coordinate global responses.

Key preparedness steps: centralise records and master files, retain privileged analysis separately where possible, ensure secure communication with advisers, and build a litigation budget and timeline for potential disputes. Early and unified responses tend to limit escalation.

Consider insurance and indemnity arrangements where appropriate, and assess whether alternative dispute resolution or mutual agreement procedures might offer quicker resolutions than adversarial litigation across multiple jurisdictions.

Executives and their advisers should treat the current reform cycle as an opportunity to modernise governance, reduce operational complexity and align wealth stewardship with global compliance expectations. The emphasis on transparency does not eliminate legal planning space, but it narrows it and makes documentation, substance and good‑faith cooperation with authorities decisive in risk management.

Begin with a rapid diagnostic: map assets and entities, prioritise high‑risk reporting exposures (crypto, custodial accounts, complex intercompany debt and non‑resident property), and set a 90‑day plan for remediation, documentation and technical reporting readiness. Engage specialised tax counsel and technology providers to implement the roadmap and to advise on jurisdiction‑by‑jurisdiction nuances.

Practical vigilance, documented substance and early cooperative engagement with tax authorities are the best protections for international wealth and property in this era of intensified transparency and cross‑border enforcement. An executive‑level compliance programme that treats reporting obligations as strategic, not just operational, will preserve value and reduce the probability of costly disputes.
