The Swiss AG (Aktiengesellschaft) and GmbH (Gesellschaft mit beschränkter Haftung) are both limited liability corporate forms under Swiss OR. The AG requires CHF 100,000 minimum capital and keeps shareholders private. The GmbH requires only CHF 20,000 but lists all quota holders publicly and mandates notarial certification for every quota transfer.

Shareholder Privacy: The Decisive Difference

For international buyers and holding structures, the privacy difference is typically the deciding factor.

An AG's shareholders are not listed in the public Commercial Register or ZEFIX. The only publicly visible persons are directors and authorised signatories. An internal share register (Aktienbuch) exists but is a private corporate document not lodged with any authority.

A GmbH's quota holders are publicly disclosed by name, domicile, and quota amount under Art. 787 OR. This information is searchable on zefix.ch at no charge and is reproduced in commercial databases across Europe. There is no statutory mechanism to exclude this disclosure, and nominee quota holder arrangements do not achieve meaningful anonymity due to the Art. 697j OR beneficial ownership requirement.

Decision rule: if shareholder confidentiality matters for any reason (publicly prominent ownership, regulatory constraints, counterparty sensitivity), choose the AG.

Transfer Mechanics: Notarisation vs Written SPA

For shelf company buyers, the transfer mechanics directly affect cost and speed.

An AG share transfer requires a written share purchase agreement and an internal share register update. No notarisation is required for the SPA itself. Structural changes (name, purpose, board) require a separate notarial act, but the underlying share transfer does not.

A GmbH quota transfer requires a public deed (öffentliche Beurkundung) before a Swiss notary under Art. 785 OR. This is mandatory for every disposition of quotas and cannot be waived. A transfer not in this form is legally void. This adds a notary scheduling step and additional cost (CHF 700-1,500 for the transfer deed alone) relative to an AG acquisition.

Capital Comparison

The minimum capital difference is significant in absolute terms:

AGGmbH
Minimum statutory capitalCHF 100,000CHF 20,000
Minimum paid-in at formationCHF 50,000 (50%)CHF 20,000 (100%)
Shelf company standardCHF 100,000 fully paidCHF 20,000 fully paid
Capital locked in companyCHF 100,000 (transfers with shares)CHF 20,000 (transfers with quotas)

For holding structures, the larger AG capital base is an advantage: more equity absorbs the participation exemption calculation base. For smaller operational businesses, the GmbH's CHF 20,000 minimum reduces the capital committed to the entity.

Tax Treatment: Identical for Both Forms

Swiss corporate income tax law makes no distinction between AG and GmbH. Both are subject to the same federal, cantonal, and communal rates. The participation exemption (Art. 69-70 DBG) applies to both forms on identical qualifying thresholds (10% or more of share/quota capital, or CHF 1 million or more cost basis). Capital tax rates are the same for both forms within a given canton.

For Shelf Company Buyers: Key Decision Points

If you are acquiring a shelf company (not incorporating fresh), three questions determine the right form:

  1. Does shareholder privacy matter? If yes, the AG is the only option: the GmbH lists all quota holders publicly and there is no effective workaround.
  2. Does the CHF 80,000 capital difference matter? Both shelf AGs (CHF 100k) and shelf GmbHs (CHF 20k) carry that capital inside the company on acquisition. The AG's larger capital base is sunk cost if it serves no holding or commercial purpose.
  3. Does transfer speed matter? The AG transfers faster: no notarisation required for the SPA. GmbH transfer requires a notary appointment for the quota deed, adding 3-7 business days depending on canton scheduling.

Frequently Asked Questions

What is the main difference between a Swiss AG and GmbH?
The AG requires CHF 100,000 minimum capital and keeps shareholders private. The GmbH requires only CHF 20,000 but lists all quota holders publicly in the Commercial Register and mandates notarial certification for every quota transfer (Art. 785 OR). Both pay identical Swiss corporate income tax.
Which is better for a Swiss holding company: AG or GmbH?
The AG is preferred for holding structures. Shareholders are not publicly listed, shares transfer freely without notarisation, and the AG is the only Swiss entity form eligible for listing on SIX Swiss Exchange. The participation exemption (Art. 69-70 DBG) applies equally to both forms.
Do AG and GmbH pay the same tax in Switzerland?
Yes. Swiss corporate income tax applies identically to AG and GmbH. The entity type does not determine the tax rate: the canton of domicile does. Zug effective combined rate: approximately 11.8%. City of Zurich: approximately 19.6%.
Can a GmbH be converted to an AG?
Yes. The Federal Merger Act (FusG) permits conversion of a GmbH to an AG without liquidation, subject to a capital top-up to CHF 100,000 if not already at that level, and a notarised conversion resolution. The converted entity retains its legal history, contracts, UID, and incorporation date.
