GmbH vs Einzelunternehmen in Germany — which is better for a sole founder?

The choice between a GmbH (Gesellschaft mit beschränkter Haftung) and an Einzelunternehmen (sole proprietorship/sole trader) is one of the most consequential decisions a German founder makes. Both have real advantages and disadvantages, and the right answer depends on profit level, risk profile, and long-term plans.\n\nFundamental differences\n\nThe Einzelunternehmen is the simplest business form — no separate legal entity, no formation process, no mandatory share capital. You register with the Gewerbeamt (if running a commercial Gewerbe rather than a liberal profession), notify the Finanzamt, and you are in business. The business's assets and liabilities are your personal assets and liabilities — there is no liability shield.\n\nThe GmbH is a separate legal entity. Your liability as a shareholder is limited to your capital contribution (€25,000 minimum, €12,500 paid up at formation). The GmbH can own assets, take on debts, and be sued — but you as an individual are not personally liable for the GmbH's obligations (absent personal guarantees or managing director liability under §43 GmbHG).\n\nTax comparison\n\nEinzelunternehmen taxation:\n- Profit taxed as personal income under Einkommensteuer: progressive rates up to 45% (42% Spitzensteuersatz from €68,429)\n- Plus 5.5% Solidaritätszuschlag on the ESt amount (above a threshold, mostly applies to higher incomes in 2025)\n- Plus Gewerbesteuer — but with the §35 EStG credit: 3.8 × Steuermessbetrag credited against personal ESt\n- At a Hebesatz of 380%, the §35 credit exactly offsets the GewSt — making Gewerbesteuer effectively zero for sole traders in moderate-rate municipalities\n- Above 380% Hebesatz, some net GewSt remains. In Munich (490%), sole traders retain approximately 3.85% net GewSt after the §35 credit\n\nGmbH taxation:\n- 15% KSt + 5.5% SolZ = 15.825% + Gewerbesteuer ~14-17% = combined 29-33% on corporate profit\n- No §35 GewSt credit — GmbH shareholders cannot offset corporate GewSt against personal income\n- Dividend extraction: 25% Kapitalertragsteuer + 5.5% SolZ on dividends paid to shareholders\n- Combined on €100 profit distributed: approximately 45-48% total tax burden (corporate tax + KapESt on dividend)\n\nRetained profit (not distributed): the GmbH shines here. Profit left in the company is taxed at only 29-33%, not the shareholder's personal marginal rate of up to 45%. If you reinvest profits in the business rather than taking them as income, the GmbH saves significant tax at higher profit levels.\n\nThe break-even analysis\nFor profit fully extracted as salary (Geschäftsführer-Gehalt): the GmbH salary is subject to Einkommensteuer and social insurance contributions, just like an employed person. This is often not tax-advantageous over an Einzelunternehmen for profits below €80,000.\n\nFor retained profit or mixed salary+dividend extraction: the GmbH advantage grows with higher profit. At €150,000 annual profit, a sole trader pays around €60,000-€65,000 in income tax. A GmbH retaining the same amount pays around €46,000-€50,000 in corporate tax — a saving of €12,000-€15,000 per year. But the saving only materialises if you do not need the money as personal income.\n\nFormation and ongoing costs\n- Einzelunternehmen: Gewerbeamt registration (€20-€50), Finanzamt notification (free), ongoing Steuerberater fees if desired\n- GmbH: Notarkosten (€1,000-€2,500), Handelsregister fees (€150-€300), annual Steuerberater for accounts and filing (€2,000-€6,000+), Bundesanzeiger filing (€18.50 minimum), and time for annual shareholder meetings and corporate housekeeping\n\nWhen incorporation makes sense\n- Annual profit consistently above €60,000-€80,000 AND significant profit is retained in the business\n- Business involves meaningful liability risk (products, client contracts, employees)\n- Long-term plan involves selling the business (GmbH shares are more easily transferred)\n- Multiple founders joining together (GmbH is the natural vehicle)\n- External investment needed (investors typically require a GmbH or AG structure)
