Sole Proprietorship vs GmbH in Germany: The Honest Comparison

Liability, the headline difference

This is the single most decision-relevant fact, so we lead with it. As a sole proprietor you carry unlimited personal liability: business debts reach your private assets, including savings and, in principle, your home. There is no separation between you and the business.

A GmbH limits liability to the company's assets (§13 GmbHG). Shareholders are shielded; if the company fails, creditors generally cannot pursue your personal wealth. That said, the shield is not absolute. It can be pierced where you sign personal guarantees (banks routinely ask for them) or where a managing director commits misconduct, such as trading while insolvent or breaching duties. So the GmbH is a strong shield, but not a guarantee against every claim.

Capital and setup cost

The entry barrier is where the two forms diverge most visibly. An Einzelunternehmen costs nothing in capital and needs no notary. A GmbH requires €25,000 in share capital, of which at least €12,500 must be paid in before the Handelsregister registration (§5 GmbHG), plus a notarised formation and an HRB entry. Foreigners may form a GmbH: there is no residency or nationality requirement to be a shareholder or managing director; you need a German business address and a notarised formation.

Item	Einzelunternehmen	GmbH
Minimum capital	€0	€25,000 (≥ €12,500 paid in)
Notary	No	Yes
Register	e.K. in HRA (if commercial)	HRB
Legal basis	HGB Kaufmann rules	§5 GmbHG

How each is taxed

The tax comparison is where most online guides go wrong by reducing it to "30% vs 45%." The honest answer is that the two forms are taxed on different logics, and a GmbH carries two layers rather than one.

Sole proprietor (tax-transparent)

A sole proprietorship is tax-transparent: profit is taxed in your hands under personal income tax. At the top, the rate is roughly 45% plus the 5.5% solidarity surcharge, around 47.5% on the highest slice of income. If the activity is commercial, trade tax (Gewerbesteuer) also applies, but a sole proprietor gets the €24,500 trade-tax allowance (§11 GewStG) and a personal trade-tax credit under §35 EStG that offsets much of the trade tax against income tax. Crucially, profit is taxed once. The effective burden varies with income, but the structure is simple: one taxpayer, one return.

GmbH (corporation, two layers)

A GmbH pays 15% corporate income tax (§23 KStG) plus a 5.5% solidarity surcharge on that tax (§4 SolzG), which works out at 0.825% of profit, giving a federal rate of 15.825%. Add trade tax (a fixed 3.5% base rate multiplied by the municipal Hebesatz) and the combined entity-level burden lands around ~30% (PwC city examples: Berlin ~30%, Frankfurt ~32%, Munich ~33%; KPMG lists 30.06% for 2025). That is only the first layer. When the GmbH distributes profit to an individual shareholder, a second layer of 26.375% dividend withholding (25% plus 5.5% soli) applies.

Scenario	Sole proprietor	GmbH
Profit	€100,000	€100,000
Entity-level tax	n/a	~€30,000 (~30%)
Owner tax on take-out	up to ~47.5% on profit (once)	+26.375% on the ~€70,000 distributed
Best when	profit is taken out / modest	profit is retained in the company / higher

The break-even depends on whether you retain profit in the company or take it out. Do not assume the GmbH is always cheaper; for money you draw immediately, the two layers can exceed the single sole-proprietor charge. To see exactly where the ~30% comes from, read our explainer on German corporate taxes.

The €24,500 trade-tax allowance only sole proprietors get

Here is an advantage that is easy to overlook. The €24,500 trade-tax Freibetrag (§11 GewStG) applies to natural persons and partnerships, including sole proprietors, but never to a corporation. A GmbH's trade income is taxed from the first euro. The base rate is a fixed 3.5% multiplied by the municipal Hebesatz (minimum 200% under §16 GewStG, in practice roughly 250–580%). At modest profit, the allowance can mean a sole proprietor pays little or no trade tax while a GmbH on the same numbers pays it in full. This is one reason the simple form often wins at lower profit levels.

Ongoing obligations and credibility

A GmbH carries running duties a sole proprietor avoids. It must keep double-entry bookkeeping, prepare annual financial statements and file them at the Bundesanzeiger (public disclosure), and submit corporate-tax and trade-tax returns at entity level. A sole proprietor below the bookkeeping thresholds may use the simple cash-basis EÜR (Einnahmen-Überschuss-Rechnung).

Both commercial forms need a Gewerbeanmeldung (trade-office registration); the exemption for liberal professionals is covered separately in our freelancer (Freiberufler) vs GmbH guide. On the credibility side, the limited-liability suffix in the name signals a capitalised, formally constituted entity, which can matter with clients, banks, and investors. Key points:

• GmbH: double-entry books, Bundesanzeiger filing, entity-level tax returns.
• Sole proprietor: often simple EÜR cash accounting below thresholds.
• Both commercial forms: Gewerbeanmeldung required.
• GmbH name signals a capitalised entity to counterparties.

When each makes sense (decision rule)

Strip away the noise and the decision is about risk, profit level, and image:

• Stay a sole proprietor when your liability risk is low, your profit is modest, and simplicity and cost dominate. The €0 setup, the €24,500 allowance, and single-layer taxation are real advantages at this stage.
• Go GmbH when liability exposure is material, such as large contracts, creditors, employees, or product and professional risk, where you want your private wealth ring-fenced.
• Go GmbH when you earn higher profits you can retain in the company, because ~30% at entity level can beat ~47.5% personally on money you do not need to draw.
• Go GmbH when credibility with clients, banks, or investors matters.

Do not assume the GmbH is always cheaper: the break-even turns on retained versus taken-out profit. The right call depends on numbers only a licensed Steuerberater should run for you.

Converting a sole proprietorship into a GmbH later

You are not locked in. A sole proprietorship can be converted into a GmbH later, and many founders start simple and incorporate once risk or profit rises. The common routes are an asset transfer or contribution-in-kind (Sacheinlage) of the business into a newly formed GmbH, or a Formwechsel or spin-off under the Reorganisation Act (UmwG). In practice this requires:

• a notarised deed,
• a valuation of the business being contributed,
• entry of the GmbH in the Handelsregister (HRB).

One caution: the conversion is not automatically tax-neutral. A book-value rollover under the UmwStG is possible, but it depends on specific elections and holding conditions. Treat conversion as "possible, with a notary and tax advice," not as a free switch. Get the structuring checked before you move.
