New Swiss AML Rules 2026: What Every Business Owner Must Know

Switzerland's anti-money laundering framework is going through the most sweeping changes it has seen in a decade. The stakes are real: fines reach CHF 250,000 per violation, the FINMA consultation window closed on June 9, 2026, and neither the size of your firm nor your revenue protects you from the new requirements. Every Swiss AG and GmbH is in scope – whether you operate a CHF 2M production company in Zurich or a CHF 15M service business in Basel.

What follows is a practical guide to what is actually changing, what each rule means for day-to-day operations, and the concrete steps every Swiss business owner should take before the new framework is fully in force.

Accounting Services Switzerland: What Swiss SMEs Get Wrong About Their Books

Professional accounting services Switzerland cover far more ground than most SME owners realise. The distance between compliant bookkeeping and genuinely useful financial management only becomes visible at audit time, during a bank financing review, or when the cantonal tax authority comes asking questions. Swiss accounting law under OR Arts. 957-962 sets double-entry bookkeeping as the mandatory baseline for companies above CHF 500,000 in turnover – but meeting the statutory minimum is not the same as running a finance function that actually supports your business.

The real value of accounting services Switzerland lies in something much more practical: monthly reconciled financials delivered within 10 business days of month-end, accurate treatment of deferred revenue and prepayments under Swiss GAAP FER, and payroll that handles Quellensteuer correctly for every cross-border worker on your team. When our team onboards a new accounting client, those three questions serve as the starting diagnostic. If your current setup cannot deliver all three, there is a strong case for outsourced accounting services Switzerland with specialists who work inside Swiss statutory requirements every day.

What Is the Swiss AMLA and Why Is It Changing in 2026?

The Swiss Anti-Money Laundering Act (AMLA, or GwG in German) defines how Swiss businesses must identify customers, document transactions, and report suspicious activity – and the 2026 revision significantly widens both the scope of the law and the consequences of falling short.

AMLA has been in force since 1997. It was built originally for financial intermediaries: banks, insurers, asset managers. Over the years it expanded to cover lawyers, notaries, and fiduciaries engaged in financial transactions. The 2026 revision is the most significant extension yet, driven largely by the Financial Action Task Force (FATF), which flagged Switzerland in its 2022 mutual evaluation for gaps in beneficial ownership transparency and enforcement.

The revisions also reflect direct lessons from the Swiss banking sector itself. The collapse of Credit Suisse in 2023 revealed how complex ownership structures could escape adequate monitoring for years. FINMA, SECO, and the Federal Council have responded with a coordinated reform package that raises standards for every participant in the Swiss financial system – from Raiffeisen and ZKB right through to individual AGs with a handful of employees.

For Swiss SME owners, the central message is straightforward. AML compliance is no longer something you can fully delegate to your bank or your lawyer and forget about. You now carry direct personal responsibility as a director.

The FINMA pOBA Revision: What Changes After June 9, 2026

FINMA's draft update to the Anti-Money Laundering Ordinance (pOBA-FINMA), published on May 12, 2026, tightens identification requirements, extends financial intermediary status to advisors and fiduciaries, and introduces new rules for crypto transactions – with the consultation period closing June 9, 2026.

Three changes in the pOBA-FINMA revision hit Swiss SME owners directly.

First: the definition of "financial intermediary" now captures a wider group of advisors – accountants, fiduciaries, business consultants, and lawyers who facilitate transactions involving cash, real estate, or changes in company ownership. If you work with any of these professionals, they are now required to apply enhanced due diligence when acting on your behalf.

Second: crypto transactions come under stricter scrutiny. Any Swiss business accepting or making payments in Bitcoin, Ethereum, or other cryptocurrencies above CHF 1,000 must maintain full counterparty identification records – even for one-off payments. Given that PostFinance and several cantonal banks now offer crypto payment rails, this is no longer a niche concern for Swiss SMEs exploring digital payments.

Third – and most consequential for directors specifically – senior management can be held personally liable for compliance failures. This is not theoretical language buried in a footnote. FINMA has already issued individual sanctions against bank executives. That same framework now extends down through the advisory chain. If your fiduciary processes a non-compliant transaction on your behalf, you carry co-responsibility as the business owner if you cannot demonstrate adequate oversight.

• New threshold for enhanced due diligence: CHF 15,000 (reduced from CHF 25,000)
• Mandatory electronic record-keeping for all covered transactions for 10 years
• Expanded scope: business advisors and management consultants classified as financial intermediaries in certain transaction types
• Crypto transactions: full KYC required for any amount above CHF 1,000
• Personal liability for directors and senior management in cases of systemic failures

The LETA Transparency Register: New Beneficial Ownership Rules

The Federal Act on the Transparency of Legal Entities (LETA) requires every Swiss AG and GmbH to identify and report beneficial owners – anyone controlling more than 25% of shares or votes – to a new non-public federal register, with fines of up to CHF 250,000 for non-compliance.

LETA is a separate piece of legislation from the pOBA revision, but the intent is closely related. Where pOBA tightens monitoring at the transaction level, LETA addresses structural transparency. The law requires Swiss companies to identify every natural person who ultimately owns or controls more than 25% of the entity and report this to a secure federal register. The register is not publicly accessible. Access is restricted to FINMA, SECO, tax authorities, and law enforcement.

For most family-owned Swiss SMEs, the identification exercise is uncomplicated: the founder or founding family are clearly the beneficial owners. But for companies with holding layers, multiple shareholders, or nominee arrangements, the analysis becomes detailed and time-consuming. FINMA expects companies to have completed their ownership mapping before the register opens for entries in H2 2026.

The CHF 250,000 fine applies to companies that fail to register, provide false information, or miss the 30-day window to update records after an ownership change. Personal director liability is also in play: the directors responsible for registration are individually accountable. This is a substantive legal obligation with active enforcement – not a checkbox exercise.

• Threshold: any natural person owning or controlling more than 25% of shares or voting rights
• Applies to: all Swiss AGs, GmbHs, cooperatives, and foundations with commercial activities
• Register: non-public federal register, accessible to authorities only
• Update obligation: any ownership change must be reported within 30 days
• Penalty: up to CHF 250,000 per violation, plus personal director liability
• Timeline: registration expected to open H2 2026 – complete your ownership analysis now

Practical Checklist: What Swiss Business Owners Must Do Now

The single most important step any Swiss SME owner can take right now is to map their full ownership structure, identify all beneficial owners, and audit their transaction monitoring and record-keeping processes – before the new rules take full effect.

Most Swiss SMEs have never formally documented their beneficial ownership in any structured way. That gap becomes a legal liability under LETA. The checklist below sets out the minimum required before the framework is fully operational.

• Map beneficial ownership: Identify every natural person with more than 25% direct or indirect control. Document the chain clearly – particularly where a holding company sits above the operating entity.
• Review your articles of association: Make sure shareholder registers are current and accurately reflect actual ownership.
• Audit transaction records: Confirm that all transactions above CHF 15,000 have adequate counterparty identification on file. Check at least the last three years.
• Brief your fiduciary and accountant: Under pOBA, they must now conduct enhanced due diligence on your behalf. Provide them the documentation they need before they have to ask.
• Review crypto exposure: If your business accepts or makes any crypto payments, implement KYC procedures for any amount above CHF 1,000 immediately.
• Assign a compliance owner internally: Designate a director or CFO-level person as responsible for AML compliance and LETA registration. Record this appointment formally.
• Estimate your compliance cost: For most Swiss SMEs, annual AML compliance runs CHF 5,000-15,000 when managed internally, or CHF 10,000-25,000 when outsourced to a specialist. Build this into your 2026/2027 financial planning.

The Corporate Tax & VAT Compliance service at Scalemetrics is already supporting clients through these requirements, folding AML readiness into broader compliance reviews.

How a Fractional CFO Protects Your SME From AML Risk

A fractional CFO brings the financial oversight, process documentation, and regulatory awareness that most Swiss SMEs cannot maintain internally – making AML compliance a managed ongoing function rather than a reactive scramble each time requirements change.

Swiss SMEs in the CHF 1M-20M revenue range typically do not need a full-time CFO to run AML compliance. What they do need is someone with enough financial and regulatory depth to design appropriate controls, keep documentation current, and respond quickly when FINMA issues updates like the pOBA revision.

Working with Scalemetrics, a fractional CFO performs several functions that directly reduce AML exposure. Clean, auditable financial records that satisfy the new 10-year retention requirement. Transaction monitoring thresholds calibrated to your business size and transaction profile. Coordination with your fiduciary and legal advisors so that everyone in the compliance chain is working from the same ownership documentation. And when new legislation like LETA requires a formal structural response, the fractional CFO manages that process without consuming weeks of your time as a business owner.

The personal liability dimension of the pOBA revision makes this particularly worth considering. If FINMA investigates a compliance failure, directors who can point to a qualified financial professional actively overseeing their compliance processes are in a materially stronger position than those who cannot.
