Switzerland 2026: the New Federal Beneficial‑ownership Register (LETA) and What Banks, Companies and Trustees Must Do

The Swiss beneficial ownership register 2026 represents the most significant shift in Swiss corporate transparency in decades. The Federal Act on the Transparency of Legal Entities (LETA), adopted by Parliament in September 2025 and cleared after the referendum period expired on 15 January 2026 without a challenge, creates a centralised, non‑public federal register that will require over 500,000 companies to submit verified beneficial‑ownership data. Running in parallel, revisions to the Anti‑Money Laundering Act (AMLA) tighten verification and evidence standards for banks, trustees and corporate service providers. With entry into force expected in the second half of 2026, every board, compliance team and fiduciary office in Switzerland needs a concrete action plan now.

Why 2026 Matters: A TL;DR Compliance Summary

Switzerland has long been an outlier among major financial centres by not maintaining a central register of beneficial owners. LETA 2026 closes that gap, aligning Swiss law with the standards of the Financial Action Task Force (FATF) and bringing the country closer to frameworks already operating in the EU, the UK and many OECD jurisdictions. The practical effect for obliged entities is threefold: identify your beneficial owners, verify their identity and control, and report the data to a new federal transparency register administered by the Federal Office of Justice (FOJ).

Here is what compliance teams should act on immediately:

• Map your entity portfolio. Determine which legal entities in your group or client base fall within LETA’s scope.
• Audit existing UBO records. Compare current shareholder registers and KYC files against the new data‑field requirements.
• Prepare IT systems. The register will operate electronically via EasyGov, the federal government’s digital business platform.
• Budget for verification. LETA and the revised AMLA require documented evidence, not just self‑declarations, of beneficial ownership.
• Train front‑line staff. Relationship managers, company secretaries and trust officers all need to understand the new obligations and timelines.

What LETA 2026 Creates, Scope and Definitions

LETA replaces the fragmented rules on beneficial‑ownership identification that previously sat within the Swiss Code of Obligations and the existing AMLA framework. It establishes a single, centralised register, the transparency register Switzerland now refers to, into which legal entities must enter data about the natural persons who ultimately own or control them. The register is administered electronically by the FOJ and overseen by the Federal Council.

Entities in Scope

In principle, all companies and legal entities domiciled in Switzerland are subject to LETA’s reporting requirements. This includes:

• Companies limited by shares (AG) and limited liability companies (GmbH), the vast majority of Swiss commercial entities.
• Partnerships limited by shares (Kommanditaktiengesellschaft) and cooperatives.
• Associations and foundations entered in the commercial register.
• Trusts and fiduciary arrangements where a Swiss trustee or corporate service provider (CSP) is involved, a critical category for the wealth‑management and private‑banking sectors.

Listed companies whose shares are traded on a recognised exchange are generally exempt, as their ownership transparency is already ensured through stock‑exchange disclosure rules. Similarly, certain public‑law entities may fall outside the scope.

Definition of Beneficial Owner and Thresholds

Under LETA, a beneficial owner is the natural person who ultimately owns or controls a legal entity, whether through direct or indirect shareholding, voting rights or other means of control. The threshold triggering a reporting obligation is broadly consistent with international norms: a natural person holding, directly or indirectly, 25 % or more of the capital or voting rights of a company, or exercising control by other means, qualifies as a beneficial owner. Where no natural person meets these criteria, companies must identify and report the persons who form the senior managing body. This aligns beneficial ownership Switzerland rules with the approach already taken by FATF Recommendation 24.

How the Revised AMLA 2026 Changes Verification and Evidence Standards

The LETA register is only half of the Swiss corporate compliance 2026 equation. Running alongside it, revisions to the AMLA impose heightened due‑diligence duties on financial intermediaries, a category that encompasses banks, securities dealers, fund managers, insurance companies and, crucially, advisors and corporate service providers.

Under the revised AMLA, obliged entities must not only collect UBO data but also verify the identity and the nature and extent of control exercised by each beneficial owner. The standard has shifted from a reliance on client self‑declarations (Form A / Form T under the existing Agreement on the Swiss Banks’ Code of Conduct, CDB) to an evidence‑based verification model. Entities are required to maintain documentary records and update them whenever material changes occur.

Banks and Financial Intermediaries

For banks, the AMLA 2026 changes translate directly into upgraded KYC and client‑lifecycle‑management procedures. FINMA‑supervised institutions will need to demonstrate that they have obtained independent verification of beneficial ownership, for example, through certified copies of share registers, notarised declarations or corporate structure charts, rather than relying solely on a signed form from the contracting party. Industry observers expect FINMA to issue updated guidance or circulars specifying the minimum acceptable evidence for different entity types, building on its existing Anti‑Money Laundering Ordinance (AMLO‑FINMA).

Corporate Service Providers and Trustees

For the first time, AMLA 2026 brings a wider group of advisory activities squarely within the Swiss AML perimeter. Corporate service providers (CSPs), including lawyers, accountants and trust companies performing qualifying activities such as forming companies, acting as directors or managing client assets, face explicit obligations to identify and verify the beneficial owners of the structures they administer. Trustees managing express trusts with a Swiss nexus must identify the settlor, protector, beneficiaries and any other natural person exercising effective control. The practical implication is that trusts and beneficial ownership can no longer be treated as a matter of private contractual arrangement; documented, verified records are now mandatory.

Who Administers the Swiss Beneficial Ownership Register 2026, What Fields Are Collected and Who Has Access

Administration: The Federal Office of Justice

The transparency register is maintained by the Federal Office of Justice (FOJ), operating under the authority of the Federal Council. The register is designed as an electronic platform, EasyGov has confirmed it will serve as the portal through which entities submit and update their data. By autumn 2026, EasyGov projects that over 500,000 companies will be legally required to submit beneficial‑ownership details through this channel.

Data Fields Collected

LETA and its draft implementing ordinance (LETO) specify that the following data must be reported for each beneficial owner:

• Full name
• Date of birth
• Nationality
• Residential address
• Nature and extent of the beneficial interest or control (e.g., percentage of shares held, description of indirect control mechanism)

Companies are also required to maintain an internal record of the supporting evidence used to verify each beneficial owner’s identity and control, a requirement that mirrors, and in some cases exceeds, the documentation standards already familiar to banks under existing CDB and AMLO‑FINMA rules.

Access Rules: Non‑Public with Designated Authority Access

Unlike the public registers maintained in several EU Member States, the Swiss transparency register is non‑public. Access is restricted to designated Swiss authorities, including law‑enforcement agencies, tax authorities, the Money Laundering Reporting Office (MROS) and FINMA, as well as regulated financial intermediaries consulting the register for KYC and due‑diligence purposes. The register is not open to the general public, nor to journalists or civil‑society organisations, a design choice that reflects Switzerland’s emphasis on data protection and financial privacy while still meeting FATF standards for competent‑authority access.

Reporting Obligations by Entity Type, Comparison Table and Timelines

The table below summarises who must report, what evidence is required and the applicable deadlines under LETA 2026. It should be read in conjunction with the entity‑specific notes that follow.

Key Legislative Timeline

• September 2025: Swiss Parliament adopts LETA.
• 15 January 2026: Referendum period expires without a referendum being launched.
• Second half of 2026 (expected): Entry into force of LETA and associated AMLA revisions, the Federal Council will set the precise date.
• Autumn 2026: EasyGov registration portal expected to be operational for mass filings.

Special Rules: Trusts, Foundations, Nominee Structures and Bearer Shares

Nominee shareholders and fiduciary holders of shares must disclose the identity of the person on whose behalf they hold the interest. Bearer shares, which Switzerland effectively immobilised in 2019 through earlier reforms requiring their conversion or deposit, will need to have their beneficial owners fully documented in the register. For foundations with discretionary beneficiary classes, the governing body must report the class of persons entitled to benefit and the individuals exercising control over distribution decisions.

Practical Compliance Checklist, Eight Steps for Companies, Banks and Trustees

This eight‑step checklist is designed as a universal starting framework. Boards, compliance officers, corporate lawyers and AML teams should adapt it to their entity structure and risk profile.

1. Conduct an entity audit. Identify every legal entity in your group or client portfolio that falls within LETA’s scope. Produce a master list with entity type, jurisdiction and current UBO records.
2. Gap‑analyse current UBO data. Compare existing shareholder registers, Form A / Form T declarations and KYC files against LETA’s required data fields (name, date of birth, nationality, address, nature and extent of control).
3. Collect and verify missing information. Where gaps exist, contact beneficial owners and obtain documentary evidence, certified share registers, notarised ID copies, structure charts, trust deeds, sufficient to meet the new evidence‑based verification standard.
4. Establish an internal UBO register. Even though data will be submitted centrally to the FOJ, each entity must maintain its own internal record of beneficial owners and supporting evidence. Define a standard template covering all LETA/LETO data fields.
5. Appoint a responsible person. Designate an internal officer (company secretary, compliance officer or external CSP) as accountable for ongoing register maintenance, data quality and timely filing.
6. Update IT systems and EasyGov access. Ensure that your entity has the necessary EasyGov credentials and that your data‑management platform can export UBO data in the format the portal requires.
7. Train relevant staff. Deliver targeted training to board members, relationship managers, trust officers and company secretaries. Cover: what triggers a reporting obligation, deadlines for initial and change filings, evidence requirements and escalation procedures for non‑cooperative beneficial owners.
8. Build an ongoing monitoring process. Establish calendar reminders and workflow triggers for the one‑month change‑notification deadline. Integrate UBO updates into corporate‑transaction checklists, onboarding workflows and annual board reviews.

For Companies

Boards of AG and GmbH entities bear ultimate responsibility. Delegating the administrative task to a company secretary or external CSP does not transfer liability. Boards should ensure that the compliance checklist for beneficial‑owner reporting is a standing agenda item at their next meeting and that a resolution authorising the initial filing is minuted.

For Banks and Financial Institutions

Banks face a dual obligation: they must file UBO data for the bank itself as a legal entity and ensure their client‑facing KYC processes meet the revised AMLA verification standard. The practical effect is a significant upgrade to client‑onboarding documentation, ongoing monitoring triggers and periodic‑review workflows.

For Trustees and Corporate Service Providers

Trustees and CSPs administer some of the most complex structures, multi‑layered trusts, purpose trusts, foundations with discretionary beneficiaries. They must map the full chain of control for each structure, obtain verified data on settlors, beneficiaries and protectors, and submit it within the statutory deadlines. Where a trust deed restricts disclosure, trustees should take legal advice on how LETA interacts with contractual confidentiality and professional privilege obligations.

KYC and Onboarding: What Banks Must Change Operationally Under AMLA 2026

Client Intake Forms and IT Fields

Banks will need to add or expand fields in their client‑intake and CRM systems to capture the full LETA data set: beneficial‑owner name, date of birth, nationality, address and a description of the nature and extent of control. Existing Form A declarations will likely need to be supplemented, or replaced, by a more detailed questionnaire and a document‑upload requirement. IT teams should liaise with compliance to define data‑field specifications, validation rules and audit‑trail requirements well before the register goes live.

Ongoing Monitoring and Update Triggers

Under the revised AMLA, banks must implement event‑driven and periodic monitoring processes. Key triggers include: a change in a client entity’s commercial‑register entry, notification of a new shareholder exceeding the 25 % threshold, a change in trust deed or letter of wishes, or adverse media or sanctions‑screening alerts. Industry observers expect best practice to settle around an annual attestation requirement, complemented by real‑time event triggers linked to commercial‑register feeds and transaction‑monitoring alerts.

Handling Conflicts and Privacy Considerations

Banks will sometimes face conflicts between LETA disclosure requirements and client expectations of banking secrecy. The legislative intent is clear: LETA obligations override contractual confidentiality to the extent necessary for register compliance. However, the non‑public design of the register, with access limited to designated authorities and regulated financial institutions, is intended to mitigate the privacy impact. Banks should update their general terms and conditions and client disclosures to reflect the new reporting obligation and manage client expectations proactively.

Trusts and Fiduciary Arrangements, Practical Issues

How Trustees Identify and Report Beneficial Owners

For express trusts with a Swiss trustee, the reporting obligation extends to the settlor, named beneficiaries (or the class of beneficiaries where individuals are not yet determined), the protector (if any) and any other natural person exercising effective control over the trust. This means that a family trust with a Swiss trustee must map every individual who has a vested or contingent interest, as well as the person or persons who can direct or override trustee decisions. Where a beneficiary class is defined by reference to a category (e.g., “descendants of the settlor”), the trustee must report the class description and the individuals currently benefiting or entitled to benefit.

Confidentiality, Legal Professional Privilege and Limits

Swiss legal professional privilege (Berufsgeheimnis) protects communications between lawyers and their clients. However, where a lawyer acts as a trustee or CSP, rather than in a pure advisory capacity, the LETA reporting obligation applies. The likely practical effect will be that trust companies and fiduciary offices staffed by lawyers must distinguish sharply between their advisory role (where privilege may apply) and their fiduciary administration role (where it does not). Early legal analysis and clear internal policies are essential to manage this boundary correctly.

Enforcement, Penalties and Cross‑Border Requests

LETA provides for administrative and criminal sanctions where entities fail to comply with their reporting obligations. Non‑compliance, including failure to file, late filing, or the submission of inaccurate or incomplete data, can result in fines and, for deliberate breaches, criminal penalties. Enforcement is expected to be conducted by the FOJ, with coordination from FINMA for regulated financial intermediaries.

Cross‑border information exchange is facilitated through existing mutual legal assistance treaties (MLATs) and administrative assistance agreements. Designated Swiss authorities may share register data with foreign counterparts where the conditions of the applicable treaty are met. This positions the Swiss transparency register as a resource for international investigations into money laundering, tax fraud and corruption, while maintaining procedural safeguards against fishing expeditions.

Conclusion: Preparing for the Swiss Beneficial Ownership Register 2026

The introduction of the Swiss beneficial ownership register 2026 through LETA, combined with the AMLA verification upgrades, marks a structural shift in how Switzerland approaches corporate transparency. For companies, the obligation is straightforward but operationally demanding: identify, verify, document and report. For banks and financial intermediaries, the changes require a meaningful overhaul of KYC workflows, IT systems and staff training. For trustees and corporate service providers, the challenge is compounded by the complexity of trust structures and the need to navigate the boundary between fiduciary duties and statutory disclosure.

The entities that act early, auditing their UBO records, upgrading their processes and training their people before the register goes live, will be best positioned to comply smoothly and avoid enforcement risk. Those that wait may face compressed timelines, data gaps and regulatory scrutiny.
