For international founders in Austria 2025–2026, choosing the legal form is one of the most critical decisions when entering the market. EPU for a quick start? GmbH for scaling and investors? Or OG with a partner? This decision affects your personal liability, your financing options with banks, your attractiveness to investors, and your tax optimization. This guide uses a clear decision tree, five concrete practical cases, and a comparison table to show you which legal form suits your business model – and when a holding GmbH structure makes sense. Typical obstacles: Staying in EPU for too long and underestimating liability risks, founding a GmbH without substance and risking bank account rejection, or building holding structures too early and too complicated. NEXORA supports you in the strategic choice of legal form: from the analysis of your business model to the coordination with tax advisors and notaries to the preparation for banks and investors – so that you have the right structure from the start.

The dilemma of international founders in Vienna: They want to start in Austria, but EPU for testing? OG with a partner? Or directly found a GmbH in Vienna? The choice of legal form feels like a decision that cannot be reversed – and in some ways it is. This article uses a clear decision tree and five real business scenarios to show you when which legal form really fits in Austria and when a holding GmbH structure makes sense. Important: This is not legal advice, but a strategic guide for your initial orientation.

Brief Overview – Legal Form Austria for International Founders

If you want to found a company in Vienna (GmbH gründen Wien), the choice of legal form in Austria is one of the most important strategic decisions. It affects your personal liability, the perception by banks and investors, your tax situation, and the scalability of your business.

Sole proprietorship (EPU) means: You alone, quick start, minimal effort – but you are personally and unlimitedly liable with your entire private assets. EPU is suitable for simple, low-risk business models or as a test phase, but is often perceived by banks and investors as "too small."

General partnership (OG) is a partnership with at least two partners. Advantage: no minimum capital, operational flexibility. Disadvantage: All partners are personally, jointly and severally liable without limitation. For international founders who want to start with a partner and consciously share responsibility, OG can be an option – but requires absolute trust and clear contractual arrangements.

GmbH (limited liability company) is the standard form for scalable business models. Liability is limited to the company's capital (at least €10,000 in cash or €35,000 total). GmbH signals seriousness to banks, investors and business partners. Effort and costs are higher, but the structure is clear and professional.

Holding GmbH means: A GmbH as a parent company that holds shares in operating companies. Purpose: Asset protection, tax optimization, international structuring. Relevant for international founders when multiple business areas, countries or investors come into play.

Comparison Table – "When Which Form?"

Decision Tree – Which Legal Form Suits You?

Use these questions to classify your situation:

Step 1: Sole Founder or Partner?

If you are starting alone:

• Low liability risk, test phase, no scaling planned (e.g. freelance consulting, design, small services) → EPU can be an entry point, but: No asset protection, difficult with banks and investors. Switch to GmbH at the latest when turnover > €100,000/year or liability risks increase.

• Scaling, financing or B2B customers planned (e.g. SaaS, agency with employees, products with liability risk) → Directly found a GmbH in Vienna. EPU is a waste of time if you want to build something serious.

If you are starting with one or more partners:

• Both actively operating, conscious joint liability, no external capital (e.g. small agency, craft) → OG is possible, but: You need a watertight partnership agreement and absolute trust. Everyone is liable for everyone.

• Different roles (one operating, one investing), scaling planned, external financing possible → GmbH is the only sensible option. OG deters investors and creates liability risks.

Step 2: Business Model and Risk Profile

Low liability risks (consulting, software without critical infrastructure):

• EPU possible for testing, but switch to GmbH at the latest with employees or > €100,000 turnover.

Medium to high liability risks (trade, import/export, products, FinTech, real estate):

• Immediately GmbH – personal liability is too risky.

Regulated areas (FinTech, payment, investment, real estate management):

• Always GmbH – banks and authorities (e.g. FMA) expect professional structures.

Five Practical Cases – Consulting, SaaS, Trading, FinTech, Real Estate Holding

Case 1: International Consulting Business

Initial situation: Founder from Germany, 15 years of experience in strategy consulting, starts solo with international clients (B2B, project volume €10,000–50,000). No physical product, low running costs, but personal consulting liability possible.

Recommended legal form in Austria: EPU to start, switch to GmbH within 12–18 months

Why this legal form?

📌 EPU allows a quick start without capital, minimal administrative effort and flexibility in the test phase.

📌 Liability risk is limited with pure consulting (no products, no employees), but not zero – therefore professional liability insurance is necessary.

📌 Switch to GmbH as soon as turnover > €100,000/year, employees are hired or large projects (€50,000+) are to be financed with banks.

📌 GmbH signals professionalism with large customers and makes financing (e.g. for office, team) easier.

When to switch to Holding GmbH?

If the consulting GmbH is running, generating profits and you want to buy real estate (e.g. office) or invest in other business areas → Holding GmbH holds real estate/investments, operative GmbH focuses on consulting.

Case 2: SaaS Platform with Scaling Potential

Initial situation: Two founders (tech + business) from Ukraine, planning SaaS platform for B2B customers (project management tool). IP (code, brand) must be protected, scaling to DACH region planned, seed round with business angels after 12 months.

Recommended legal form in Austria: Immediately found a GmbH in Vienna

Why this legal form?

📌 Investors expect GmbH – no business angels or VCs invest in EPU or OG.

📌 IP (code, brand) belongs to the GmbH – not personal property of the founders, which facilitates exit scenarios and sale.

📌 ESOP (Employee Stock Option Plan) possible – you can give employees virtual shares, which is not possible with EPU/OG.

📌 Limitation of liability – if SaaS platform has data leak or GDPR violation, GmbH is liable (not founders personally), limited to company capital.

When to switch to Holding GmbH?

Before the first investment round: Founders found Holding GmbH (holds shares in operative SaaS-GmbH). Investors buy shares in operative GmbH, founders retain control over Holding. Exit scenarios (sale, dividends) tax-optimized via Holding.

Case 3: Import/Export and Trading

Initial situation: Founder from Serbia, plans import of electronics from China to Austria/Germany. High goods risks (quality, customs, delivery delay), supplier credits and bank loans necessary, B2B customers (traders).

Recommended legal form in Austria: Immediately GmbH

Why this legal form?

• Goods risk = liability risk – faulty products, warranty, recalls. With EPU or OG you are personally liable without limitation → risk of insolvency for private assets.

• Banks do not give EPU trade credits – for import/export you need credit lines, letters of credit, factoring. GmbH is a prerequisite for > €50,000 financing.

• Suppliers trust GmbH more – serious appearance, clear contractual structures.

• Customs and authorities – GmbH signals professional structure, which facilitates audits.

When to switch to Holding GmbH?

If Trading-GmbH is running profitably and you want to expand (e.g. own logistics-GmbH, retail-GmbH for end customers) → Holding GmbH holds all operative companies, separates risks and optimizes cash flows between companies.

Case 4: FinTech Startup (Payment, Lending, Investment)

Initial situation: Three founders (two from Austria, one from UK), planning payment platform for DACH region. Regulation by FMA necessary, bank license or e-money license, high compliance requirements (AML/KYC), investors from Series A planned.

Recommended legal form in Austria: Immediately GmbH, medium-term holding structure

Why this legal form?

• In practice, only corporations (especially GmbH or AG) are eligible for licensed financial services; EPU or OG are virtually not an option. FMA checks managing directors, equity, compliance.

• Banks expect GmbH – without GmbH no company account with Austrian banks for FinTech (compliance reasons).

• Investors and license – Series A investors expect clear corporate governance, professional structures, ESOP. Only possible with GmbH.

• Limitation of liability critical – FinTech has regulatory risks (money laundering suspicion, GDPR, customer data). Personal liability would be life-threatening.

When to switch to Holding GmbH?

Before licensing: Holding GmbH (Austria) holds operative FinTech-GmbH (Austria). Why? If license is necessary in several countries (e.g. Germany, Switzerland), Holding holds all country companies. Also: IP (software, brand) can be in Holding, operative GmbH licenses IP → tax advantages.

Case 5: Real Estate Holding and Cash Flow Strategy

Initial situation: Founder couple from Russia, operates successful e-commerce business (operative GmbH has been running for 3 years, profit €200,000/year). Want to invest profits in real estate (office buildings, rental properties) and structure tax-optimized.

Recommended legal form in Austria: Holding GmbH + operative GmbH(s)

Why this legal form?

• Asset protection – operative e-commerce-GmbH has business risks (product liability, suppliers, customers). Real estate in separate real estate-GmbH (or directly in Holding GmbH) → if operative GmbH is insolvent, real estate is protected.

• Tax optimization – profits from operative GmbH as dividend to Holding GmbH tax-free (Austrian Schachtelprivileg). Holding reinvests in real estate or other investments without KESt deduction.

• Cash flow strategy – Holding GmbH holds real estate, rents to operative GmbH (office) or to third parties. Rental income flows tax-efficiently into Holding.

• Exit scenario – if you want to sell operative e-commerce-GmbH, Holding holds the shares → proceeds from sale flow into Holding, can be reinvested tax-efficiently (in real estate or new businesses).

When to switch to Holding GmbH?

Now – operative GmbH generates profits, real estate investments planned. Structure: Holding GmbH (roof) → holds 100% operative e-commerce-GmbH + holds real estate (directly or via real estate-GmbH).

Typical Mistakes of International Founders When Choosing a Legal Form

• Staying in EPU for too long – liability risk and missed opportunities. International founders often start with EPU "for testing" and stay in it for too long because the switch to GmbH seems complex. Problem: With increasing turnover (> €100,000/year) and employees, the liability risk grows exponentially.

• OG with partner without clear agreements – conflicts and joint liability. OG seems attractive: no minimum capital, quick start with partner. But: Each partner is personally and jointly and severally liable for all liabilities – also for errors or debts of the partner.

• GmbH without substance and without a clear business model – bank account refused. International founders read "GmbH is the standard form" and immediately found a GmbH – but without a concrete business plan, without operative business, without substance.

• Holding GmbH too early or too complicated – unnecessary costs and complexity. International founders read about holding structures and want to start "tax-optimized". Problem: Holding GmbH from the beginning (without operative business) creates double costs.

• Legal form without coordination with tax advisor and bank – nasty surprises. Many international founders choose a legal form based on online research, without talking to a tax advisor (tax optimization, social security) or bank (account opening, financing).
