Types of Companies in Austria | 9 Legal Structures Compared

Introduction to Entity Types in AustriaCopy link to section

Austria is a landlocked republic in Central Europe, sharing borders with Germany, Switzerland, Liechtenstein, Italy, Slovenia, Hungary, Slovakia, and the Czech Republic. As a member of the European Union and the Eurozone, it operates under a standard corporate tax framework with a territorial dimension, making it relevant for businesses seeking a regulated, treaty-connected European base.

Company registration and ongoing compliance fall under the jurisdiction of the Firmenbuch, Austria's commercial register administered through the federal court system. Entries are publicly accessible and legally binding from the date of registration.

The types of business entities in Austria span both incorporated and unincorporated structures. Available legal forms include the Aktiengesellschaft (AG), Gesellschaft mit beschränkter Haftung (GmbH), Societas Europaea (SE), Offene Gesellschaft (OG), Kommanditgesellschaft (KG), Stille Gesellschaft, Zweigniederlassung, Repräsentanzbüro, and Eingetragener Unternehmer (EU). Each form carries distinct implications for liability, governance, minimum capital, and taxation. This article examines each structure in detail to help you determine which legal form fits your operational and compliance requirements.

An Overview of Business Structures in AustriaCopy link to section

Austrian company law recognises several distinct entity types, each governed primarily by the Unternehmensgesetzbuch (UGB) and supplementary legislation such as the GmbH-Gesetz and the Aktiengesetz. The structural options range from sole proprietorships to European-level corporate forms, and each carries different implications for liability, taxation, and governance.

Business Structures at a GlanceCopy link to section

Each of these structures is examined in full in the sections below.

Aktiengesellschaft (AG) — Joint Stock CompanyCopy link to section

Aktiengesellschaft AG Austria formation is governed by the Aktiengesetz (AktG), enacted in 1965 and substantially amended over subsequent decades to align with EU corporate law directives. The AG carries separate legal personality, meaning the company's obligations are entirely distinct from those of its shareholders.

Shares in an AG are freely transferable by default, and the entity can be either publicly listed or privately held. This structural flexibility makes it a common vehicle for large enterprises, institutional investors, and businesses planning a future public offering.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: Subject to 23% corporate income tax; Austria's tax authority (Finanzamt) also applies 25% withholding tax on dividends, 20% VAT on standard supplies, and capital gains tax at the shareholder level; participation exemption may apply to qualifying dividend receipts.
• Annual Compliance: Annual financial statements must be audited and filed with the Firmenbuch; listed AGs follow additional disclosure obligations under the Börsegesetz.
• Economic Substance: No specific substance regime, but genuine management and control must align with Austrian tax residency claims.
• Treaty Access: Qualifies for benefits under Austria's extensive double taxation treaty network as a resident entity.
• Conversion: An AG can be converted into a GmbH or SE under the EU Cross-Border Conversion Directive as transposed into Austrian law.

ClosingCopy link to section

The AG suits large-scale trading operations, holding structures, and businesses seeking access to capital markets, though its mandatory dual-board structure and EUR 70,000 minimum capital requirement make it administratively heavier than simpler corporate forms.

Gesellschaft mit beschränkter Haftung (GmbH) — Limited Liability CompanyCopy link to section

The GmbH Austria limited liability company is governed by the GmbH-Gesetz (GmbHG), enacted in 1906 and substantially amended over the decades. It holds separate legal personality, meaning the entity itself — not its shareholders — bears contractual obligations and liabilities.

Shareholders' exposure is capped at their respective capital contributions. This hybrid structure combines the liability protection of a corporation with the operational flexibility typically associated with smaller private firms, making it the most widely used commercial entity form in the country.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: Subject to 24% corporate income tax (KöSt) on worldwide profits; standard VAT rate of 20% applies; withholding tax of 27.5% on dividend distributions to non-residents, subject to applicable double tax treaty reductions; no stamp duty on share transfers.
• Annual Compliance: Annual financial statements must be filed with the Firmenbuch; audit required once the entity exceeds two of three statutory thresholds (turnover, balance sheet total, headcount).
• Economic Substance: No formal substance test under domestic law, though tax residency and transfer pricing rules require genuine management and control to be exercised from Austria.
• Treaty Access: Qualifies for Austria's extensive tax treaty network (90+ treaties) and EU directives, including the Parent-Subsidiary Directive.
• Conversion: A GmbH may be converted into an AG under the Umwandlungsgesetz without liquidation, subject to meeting the AG's minimum capital threshold.

ClosingCopy link to section

The GmbH suits trading operations, holding structures, and IP-holding vehicles where limited liability and private ownership are priorities. Its principal constraint is the EUR 35,000 minimum capital requirement, which raises the initial cost of formation relative to some other jurisdictions.

Societas Europaea (SE) — European CompanyCopy link to section

Societas Europaea SE registration Austria falls under Council Regulation (EC) No 2157/2001, supplemented by the Austrian SE-Gesetz (SEG), which implements the EU directive at the national level. The SE carries separate legal personality and offers shareholders limited liability, making its structural profile broadly comparable to an AG — the national joint stock company form it most closely mirrors.

Formation, however, follows distinctly supranational rules. SE formation Austria cross-border rules require that the entity arise through a prescribed EU-level procedure: merger of companies from at least two member states, formation of a holding SE, conversion of an existing AG, or establishment as a subsidiary SE. A purely domestic formation without a cross-border element is not permitted.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: Subject to Austrian corporate income tax at 23% (as of 2024); VAT registration obligations apply in the standard manner; withholding tax on dividends generally 27.5%, reducible under applicable tax treaties or the EU Parent-Subsidiary Directive.
• Employee Involvement: SE formation triggers mandatory negotiation of employee involvement arrangements under the Austrian SE-Mitbestimmungsgesetz; this can extend the formation timeline significantly.
• Annual Compliance: Annual financial statements must be prepared and filed with the Firmenbuch; audit requirements apply as for an AG.
• Conversion: An SE registered in Austria may convert into an Austrian AG without dissolution or loss of legal personality, and vice versa.
• Seat Transfer: The SE's registered office may be transferred to another EU member state without dissolving the entity — a structural option unavailable to purely national company forms.

ClosingCopy link to section

The SE suits multinational groups seeking a pan-European holding or operational vehicle with the flexibility to relocate the registered seat across the EU without restructuring. The seat-transfer facility is its principal structural advantage; the mandatory employee involvement process and the EUR 120,000 minimum capital requirement are practical constraints that make it less accessible for smaller businesses.

Partnerships in Austria [Offene Gesellschaft (OG), Kommanditgesellschaft (KG), Stille Gesellschaft]Copy link to section

Austrian partnership structures in Austria OG KG are governed primarily by the Unternehmensgesetzbuch (UGB), which came into force in 2007, replacing the earlier Handelsgesetzbuch. The UGB regulates both the Offene Gesellschaft (OG) and the Kommanditgesellschaft (KG), while the Stille Gesellschaft operates as a contractual arrangement without separate legal personality.

Each structure differs in how liability is allocated among participants. The OG exposes all partners to unlimited joint liability, whereas the KG separates at least one general partner bearing unlimited liability from one or more limited partners whose exposure is capped at their registered capital contribution.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: OG and KG are fiscally transparent — profits pass through to partners and are taxed at the individual or corporate level depending on partner type; no entity-level corporate income tax applies. VAT registration obligations follow standard Austrian rules under the Umsatzsteuergesetz (UStG). The Stille Gesellschaft is similarly transparent, with the silent partner taxed on their profit share as passive income.
• Annual Compliance: OG and KG must file annual financial statements with the Firmenbuch if they meet size thresholds under the UGB; smaller partnerships have reduced obligations.
• Treaty Access: Pass-through treatment may complicate access to Austria's double tax treaty network, as treaty eligibility generally requires the income recipient to be a taxable entity.
• Conversion: Both OG and KG can be converted into a GmbH or AG under the Umwandlungsgesetz (UmwG) without full dissolution.

Sub-TypesCopy link to section

GmbH & Co KG

A widely used hybrid where a GmbH acts as the sole Komplementär, effectively capping unlimited liability exposure. This structure is common for family businesses and real estate holdings where partners want limited liability at the general partner level without incorporating a full share-capital entity.

Atypische stille Gesellschaft

Distinguished from the standard Stille Gesellschaft by granting the silent partner participation in asset appreciation and losses, not only profits. This variant is frequently used in structured finance and employee participation arrangements.

ClosingCopy link to section

Partnership structures suit professional service firms, family-owned trading operations, and real estate joint ventures where pass-through taxation is operationally preferable. The absence of minimum capital requirements reduces entry barriers, though unlimited liability for general partners remains a substantive structural risk that requires careful contractual planning.

Foreign Business Presence in Austria [Zweigniederlassung, Repräsentanzbüro]Copy link to section

Establishing a foreign company branch office Austria requires registration under the Austrian Commercial Code (Unternehmensgesetzbuch, UGB) and the Act on Business Licensing (Gewerbeordnung, GewO 1994). A branch (Zweigniederlassung) is not a separate legal entity — it remains an extension of the parent company, which retains full liability for its operations.

Registration for a Zweigniederlassung Austria registration is handled through the Austrian commercial court (Firmenbuch), which maintains the public register. The representative office (Repräsentanzbüro), by contrast, is not registered in the Firmenbuch and is restricted to auxiliary activities such as market research and liaison functions.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: The branch is subject to Austrian corporate income tax (25% standard rate) on locally sourced profits; VAT registration is required if turnover thresholds are met; withholding tax may apply to profit remittances depending on applicable double tax treaties.
• Economic Substance: The branch must maintain a genuine operational presence; purely nominal offices risk reclassification.
• Annual Compliance: Branches must file annual financial statements in Austria, mirroring the parent's accounts where required by the Firmenbuch.
• Treaty Access: Access to Austria's tax treaty network depends on the parent entity's jurisdiction and treaty terms.
• Restrictions: The Repräsentanzbüro cannot invoice clients, generate revenue, or conclude contracts on behalf of the parent.

ClosingCopy link to section

A branch suits foreign firms testing the Austrian market or executing contracts locally, though the absence of liability separation from the parent is a meaningful structural exposure. Opening a branch in Austria as a foreign company avoids the capitalisation requirements of a subsidiary but transfers full legal and financial risk to the parent entity.

Eingetragener Unternehmer (EU) — Sole ProprietorshipCopy link to section

The Eingetragener Unternehmer sole proprietorship Austria is the simplest form of business registration available to individuals operating commercially under Austrian law. Governed by the Unternehmensgesetzbuch (UGB), the commercial code that came into force in 2007, this structure carries no separate legal personality — the proprietor and the business are one and the same legal entity.

Because there is no liability shield, your personal assets are fully exposed to business creditors. Registration is mandatory once annual turnover exceeds EUR 700,000 (measured over two consecutive financial years), though voluntary registration is permitted below that threshold.

Key CharacteristicsCopy link to section

Focus PointsCopy link to section

• Taxation: Subject to personal income tax (Einkommensteuer) at progressive rates up to 55%; VAT registration required once turnover exceeds EUR 35,000 annually; no corporate tax applies; no withholding tax on profit withdrawals as there are no dividends.
• Annual Compliance: Bookkeeping obligations depend on turnover thresholds under the UGB; above EUR 700,000, full double-entry accounting is required.
• Treaty Access: As a pass-through structure, treaty benefits apply at the individual proprietor level under Austria's bilateral tax treaty network.
• Conversion: Can be converted into a GmbH or other capital structure, though the process requires formal restructuring and new registration with the Firmenbuch.

Closing RemarksCopy link to section

This structure suits freelancers, tradespeople, and small-scale commercial operators who want a low-cost entry point without governance formalities. The absence of minimum capital is its clearest practical advantage; unlimited personal liability remains the defining constraint.

How to Choose the Right Entity Type in AustriaCopy link to section

Knowing how to choose a company type in Austria requires more than comparing registration fees — the structural decision has legal, tax, and operational consequences that persist for the life of the business.

Why Your Entity Choice MattersCopy link to section

Choosing the wrong entity structure produces concrete, correctable-but-costly outcomes:

• Forming a GmbH when a branch (Zweigniederlassung) suffices for your operational model means bearing the full capital requirement of EUR 10,000 and ongoing annual filing obligations that branches are not subject to in the same form.
• Selecting an entity without qualifying as a tax resident can disqualify your business from accessing Austria's double taxation treaty network, preventing withholding tax reductions in counterpart countries.
• Registering a sole proprietorship (Eingetragener Unternehmer) when your activity requires a licensed trade under the Gewerbeordnung 1994 results in operating without valid authorization, which can lead to administrative penalties or forced cessation.
• Choosing an AG when a single-person consultancy is the actual model introduces mandatory supervisory board requirements and audit obligations that generate disproportionate annual compliance costs.

Key Factors to ConsiderCopy link to section

• Business Activity: Active trading, passive asset-holding, and regulated sectors such as banking or insurance each point toward a different permitted structure under Austrian commercial law.
• Ownership and Management: A sole founder with no co-investors may find the GmbH's flexible single-director structure more practical than the AG's mandatory two-tier governance model.
• Tax Objectives: Your need for full corporate tax residency, participation exemption eligibility, or access to the EU Parent-Subsidiary Directive will determine whether a capital company is required.
• Substance Capacity: If you cannot maintain genuine management and decision-making activity locally, the entity type chosen must still satisfy the economic substance expectations applied by Austrian tax authorities.
• Exit Strategy: Not all Austrian entity types permit redomiciliation or conversion without dissolution; the Societas Europaea offers cross-border seat transfer options that domestic entities do not.
• Privacy Requirements: Beneficial ownership data is disclosed to the Wirtschaftseigentümer Register (WiEReG) regardless of entity type, but the extent of public register disclosure varies by structure.

ConclusionCopy link to section

Austria offers a defined set of legal structures, each suited to a distinct operational and ownership profile. This setting up a company in Austria guide has covered the full spectrum: the GmbH remains the most registered entity in the country, favored by small and mid-sized firms for its manageable capital requirements and liability protection. The AG suits larger enterprises requiring access to capital markets. Partnerships such as the OG and KG serve businesses where personal involvement and shared liability align with the operating model. The SE addresses cross-border European structures, while the Zweigniederlassung and Repräsentanzbüro give foreign firms a regulated path to local presence without full incorporation.

Regulated by the Firmenbuch and overseen through established commercial law, Austria's corporate framework continues to attract international business, supported by a broad double taxation treaty network. Your choice of structure shapes everything from governance to tax treatment.
