Swiss GmbH vs AG: Which Company Structure Is Right for You?

Most foreign entrepreneurs researching Swiss company formation spend hours comparing GmbH and AG online — and almost all of them choose the wrong comparison framework. They focus on prestige, banking perception, or what sounds more serious. They should be asking a different question entirely: which structure gives me the control, flexibility, and cost profile I actually need for the next three to five years?

The GmbH (Gesellschaft mit beschränkter Haftung) and the AG (Aktiengesellschaft) are both limited liability vehicles under Swiss law. Both protect your personal assets. Both pay the same corporate tax. Both can be 100% foreign-owned. The differences are structural — capital requirements, governance rules, share transferability, and ongoing formalities — and for most foreign founders, these structural differences decisively favour the GmbH.

This guide covers every dimension of the comparison in detail. By the end, you will know exactly which structure suits your situation, what each costs to form and run, and how to proceed. If you are ready to start, our company formation service handles the entire process remotely.

The Fundamental Difference: What Each Structure Actually Is

The GmbH is Switzerland’s equivalent of a private limited company (LLC in the US, SARL in France). It has ‘partners’ (Gesellschafter) rather than shareholders. Each partner’s stake is documented in the Commercial Register and in a signed partners register. Transfers of GmbH stakes require a notarised deed — you cannot simply hand over a share certificate. The GmbH is designed for stable, closely-held ownership structures.

The AG (Aktiengesellschaft) is Switzerland’s joint-stock company, equivalent to a public limited company (PLC in the UK, SA in France). It has shareholders, issues share certificates, and — critically — shares can be transferred without notarial involvement. The AG is designed for ownership that may change: bringing in investors, granting equity to employees, or eventually listing on a stock exchange.

This fundamental difference in share transferability cascades through everything else. The AG is built for growth and change; the GmbH is built for control and stability. Neither is objectively superior — it depends entirely on where you are in your business journey.

Capital Requirements: The CHF 20,000 vs CHF 100,000 Decision

The most immediately practical difference is the minimum share capital. A GmbH requires CHF 20,000, which must be fully paid up at formation. An AG requires CHF 100,000, of which at least 50% (CHF 50,000) must be paid at formation, with the remainder callable later.

For most entrepreneurs, CHF 20,000 is real money but not a prohibitive barrier. The critical point: this is not a fee or a tax. It is equity — your company’s own capital, released to the company’s bank account after formation and available for business expenses. You are not ‘spending’ CHF 20,000; you are capitalising your company with CHF 20,000 that now belongs to the business.

For the AG, the same logic applies — CHF 50,000 minimum at formation is equity, not a cost. But the higher bar does filter out companies that are not yet confident about committing capital. For early-stage foreign entrepreneurs testing Swiss market entry, the GmbH’s lower threshold is practically significant.

Governance: Who Controls the Company

In a GmbH, all major decisions are made by the Gesellschafterversammlung (partners’ meeting). Each partner has voting rights proportional to their capital contribution. You can — and most foreign-owned GmbHs do — structure the articles to give the majority partner (you) veto rights over fundamental decisions. This gives founders very strong ongoing control, even if additional partners are later admitted.

In an AG, governance is more formal. The Verwaltungsrat (board of directors) manages the company day-to-day, while the Generalversammlung (general meeting) handles major decisions. Shareholders elect the board. If you own 100% of the AG, you control both layers. But the AG structure is designed to accommodate outside shareholders — which means the governance rules are more rigid and formal, with statutory requirements for board composition, meeting minutes, and annual general meetings.

For a single-founder or small-team company that will remain closely held, the GmbH’s simpler governance is an advantage. There are fewer formal requirements, fewer mandatory meetings, and more flexibility in structuring decision-making authority. For a company that will eventually have investors, co-founders with equity, or an employee stock option plan, the AG’s structure becomes necessary.

Privacy: Who Can See Your Ownership

This is a point almost never mentioned in comparisons — and it is significant for some entrepreneurs. In a GmbH, all partners and their percentage stakes are listed in the Swiss Commercial Register (Handelsregister), which is publicly searchable. Anyone can look up your company and see exactly who owns it and in what proportion.

In an AG, the Commercial Register lists only the directors (Verwaltungsrat members). Shareholders are not publicly disclosed — they appear in the internal Aktienbuch (share register), which is not public. If privacy of ownership is important to you — for personal security, competitive, or professional reasons — the AG provides a degree of confidentiality that the GmbH does not.

Important caveat: Swiss banks and fiduciaries will always identify the true beneficial owner(s) of an AG as part of KYC. Ownership privacy is from the general public, not from regulated institutions. And for any company ultimately subject to the OECD’s beneficial ownership transparency standards, privacy should be considered limited rather than absolute.

Conversion: Can You Switch From GmbH to AG Later?

Yes — and this is an important strategic point. You can form a GmbH now and convert it to an AG later if your business grows to the point where you need the AG structure. The conversion process (Umwandlung) requires a notarised deed, additional capital contribution to reach CHF 100,000 (if not already there), and a Commercial Register update. It is not free — typical costs are CHF 3,000-8,000 including notary and legal fees — but it is entirely feasible.

The practical implication: if you are unsure which structure you need, start with a GmbH. You gain the lower capital requirement, simpler governance, and lower formation cost. If the business develops in a direction requiring an AG — institutional investors, employee equity, complex share classes — you can convert. You do not need to choose the AG ‘in case’ you grow into it.

Costs: Formation and Annual Maintenance

Which Should You Choose? The Decision Framework

Choose the GmbH if: you are a single founder or small team forming a company for the first time in Switzerland; you want to minimise capital commitment; you value simple, flexible governance; you do not need to transfer shares frequently or bring in investors in the near term; and you want the lowest-cost path to a legally operational Swiss company.

Choose the AG if: you have institutional investors or plan to raise equity funding; you want to grant employee stock options (easier in AG); you are building toward a potential public listing; you want ownership privacy (AG shareholders not public); your industry has stakeholders who specifically require the AG structure (some regulated financial services); or you are converting an existing group structure that already uses the AG format.

The honest answer for 80-90% of foreign entrepreneurs: the GmbH is the right choice. It gets you a fully functional, credible Swiss company at lower cost, with simpler governance and adequate flexibility. You can always convert to AG later. Start with what fits today’s reality, not a hypothetical future that may not materialise. Our GmbH formation service covers every step of the process remotely.

Which Structure Fits Your Situation: Six Scenarios

The theoretical comparison between GmbH and AG resolves quickly when you apply it to specific business situations. Here are the six most common scenarios for foreign entrepreneurs, and the right answer for each.

Scenario 1: Single Founder, No External Investors

This is the most common scenario for foreign entrepreneurs approaching Virtual Office Zug. One person, full ownership, no outside investors, business generating revenue or expected to do so within 12 months.

The answer: GmbH, every time. The CHF 20,000 capital requirement is workable. The governance is simple — you make all decisions. The ownership is 100% yours. The formalities are minimal. The annual cost is lower. And if your business eventually grows to where you need an AG, conversion is possible at a manageable cost.

The only exception within this scenario: if you are specifically concerned about ownership privacy (the GmbH lists partners publicly in the Commercial Register), the AG provides confidentiality. But for most founders, this is not a practical concern.

Scenario 2: Two or Three Co-Founders

Two people forming a company together, splitting ownership 50/50 or 60/40.

The answer: GmbH still works well. Two co-founders can each hold their GmbH quota, with a detailed shareholder agreement covering decision-making, exit provisions, and buyout rights. The notarised transfer requirement for GmbH quotas actually provides some protection — you cannot have a co-founder quietly sell their stake to a third party without your knowledge and notarial involvement.

Key document: a shareholders agreement (Gesellschaftervertrag or separate SHA) that governs what happens if one co-founder wants to exit, what happens on death or incapacity, and how deadlock situations are resolved. Especially critical in a 50/50 GmbH where deadlock can paralyse the company.

Scenario 3: Raising External Investment

You are building a startup and plan to raise funding from angel investors or VCs within 12–24 months.

The answer: AG, or plan to convert. Institutional investors universally prefer the AG for equity investment. AG shares are simpler to transfer and issue than GmbH quotas (no notary required for share transfers), multiple share classes are straightforward (important for preference shares and liquidation preferences), and equity incentive plans (ESOP) work more cleanly in the AG framework.

If you are not sure when or whether you will raise, form a GmbH now and convert when the need arises. Conversion costs CHF 3,000–8,000 and takes 4–6 weeks — a manageable one-time cost when you have investor term sheets in hand.

Scenario 4: Holding Structure for a Group of Companies

You want to create a Swiss holding company that will own subsidiaries in multiple countries.

The answer: AG for the holding. When a holding company eventually needs to be reorganised — bringing in a family trust as shareholder, restructuring for an exit, or adding a co-investor — the AG’s share transferability without notarisation makes the process cleaner. The AG’s higher capital (CHF 100,000) is also appropriate for a holding that owns valuable subsidiaries. The holding structure benefits from Switzerland’s participation exemption, making dividends from subsidiaries effectively tax-free at the Zug holding level.

Scenario 5: Crypto or Blockchain Company

You are launching a crypto project, DeFi protocol, NFT studio, or Web3 service company.

The answer depends on your stage and structure. For an early-stage crypto operating company (development studio, consulting, services), the GmbH is fine. For a protocol governance structure, consider a Swiss foundation (Stiftung) for the governance layer alongside a GmbH or AG as the commercial entity. For a company planning to issue tokens or raise from VCs, the AG’s cleaner equity structure becomes important. See our complete Crypto Valley guide for the full structural picture.

Scenario 6: Converting from GmbH to AG

You started with a GmbH and now need the AG’s investor-ready structure.

The conversion is procedurally straightforward. Notarised deed, capital top-up to CHF 100,000 if needed, Commercial Register update. Cost: CHF 3,000–8,000. Timeline: 4–8 weeks. The company maintains the same legal identity and all existing contracts continue unchanged. It is not disruptive to ongoing business and is the standard upgrade path for companies that outgrow the GmbH.
