Starting a Sole Proprietorship in Germany: A Comprehensive Guide
Complete guide to the Einzelunternehmen and Freiberufler in Germany — registration, tax, EÜR accounting, liability, pension obligations, and GmbH conversion.
Gewerbetreibender vs Freiberufler: The Core Distinction
German sole traders fall into two legally distinct categories. A Gewerbetreibender (commercial trader) conducts activities under §15 EStG. A Freiberufler (liberal professional) provides services under §18 EStG — including doctors, lawyers, architects, engineers, tax advisors, journalists, artists, and IT consultants engaged in creative or analytical work. The distinction determines Gewerbe registration, IHK membership, and Gewerbesteuer liability. Misclassification — particularly for IT professionals — is actively scrutinised by German Finanzämter.
- §15 EStG: commercial income — triggers Gewerbe registration and IHK membership
- §18 EStG: freelance income — no Gewerbe, no IHK, no Gewerbesteuer
- Freiberufler: doctors, lawyers, architects, engineers, journalists, artists, teachers
- IT consultants: Freiberufler for creative/analytical work; Gewerbe for routine code
- Finanzamt makes binding classification — advance ruling available on request
Gewerbeanmeldung: Commercial Business Registration
Gewerbetreibende must register at the local Gewerbeamt under §14 GewO before commencing business. The fee is €20–€65 depending on the Gemeinde. The Gewerbeschein is typically issued the same day. The Gewerbeamt automatically notifies the Finanzamt, IHK, and Berufsgenossenschaft (statutory accident insurer). IHK membership is automatic and compulsory under §2 IHKG, with annual contributions starting at €0 for new businesses with low turnover in the first two years.
- §14 GewO: Gewerbeanmeldung required before starting commercial activity
- Fee: €20–€65 at local Gewerbeamt (varies by Gemeinde)
- Gewerbeamt notifies Finanzamt, IHK, and Berufsgenossenschaft automatically
- IHK membership compulsory under §2 IHKG — from €0 for early-stage businesses
- Gewerbeschein issued same day — business may commence immediately
Freiberufler Registration: Finanzamt Only
Freelancers skip the Gewerbeamt entirely and simply submit the §138 AO Fragebogen zur steuerlichen Erfassung to the local Finanzamt. This is the only registration required. The Finanzamt assigns a Steuernummer within approximately 4 weeks, which must appear on all invoices under UStG §14(4). No IHK, no court, no notary. Freiberufler are not IHK members but may voluntarily join professional associations relevant to their field.
- Freiberufler: submit §138 AO Fragebogen to Finanzamt only
- No Gewerbeanmeldung, no IHK, no Handelsregister entry
- Steuernummer issued within approx. 4 weeks of submission
- No invoices before Steuernummer — legally required under UStG §14(4)
- USt-IdNr: requested separately from BZSt for cross-border EU services
Gewerbesteuer: Trade Tax Rules for Sole Traders
Commercial sole traders pay Gewerbesteuer (trade tax) only on Gewerbeertrag above the annual Freibetrag of €24,500 (GewStG §11(1)). The effective rate depends on the municipal Hebesatz — the national average of ~400% yields approximately 14% on earnings above the threshold. Crucially, Gewerbesteuer paid is offset against personal Einkommensteuer under EStG §35, largely eliminating double-taxation. Freiberufler under §18 EStG are fully exempt — a substantial structural advantage.
- Gewerbesteuer Freibetrag: €24,500/year — earnings below this are tax-free
- Average Hebesatz ~400%: Hamburg 470%, Munich 490%, rural areas 300%
- Effective GewSt at 400% Hebesatz: ~14% on earnings above Freibetrag
- EStG §35 offset: GewSt largely eliminates double-taxation at typical income levels
- Freiberufler (§18 EStG): fully exempt from Gewerbesteuer
EÜR: Simplified Cash Accounting for Sole Traders
Sole traders with annual turnover below €600,000 AND profit below €60,000 may use the Einnahmen-Überschuss-Rechnung (EÜR) under §4(3) EStG instead of double-entry bookkeeping. EÜR is a cash-basis income-minus-expense statement submitted as Anlage EÜR with the annual Einkommensteuererklärung. No balance sheet or depreciation schedule is required. Steuerberater fees for EÜR clients typically run €500–€1,500/year versus €2,000–€5,000+ for GmbH balance-sheet clients.
- §4(3) EStG: EÜR allowed for turnover <€600,000 AND profit <€60,000
- No balance sheet (Bilanz) required — cash-in minus cash-out
- Filed as Anlage EÜR with annual Einkommensteuererklärung via ELSTER
- Steuerberater EÜR fee: ~€500–€1,500/year vs. €2,000–€5,000+ for GmbH
- Exceeding thresholds: Finanzamt issues Buchführungspflicht — double-entry required
Unlimited Personal Liability: The Core Risk
The defining legal risk of the Einzelunternehmen is unlimited personal liability. There is no separation between business and personal assets — savings, property, vehicles, and future income are all exposed to business creditors. There is no Haftungsbeschränkung equivalent to GmbHG §13(2). Practical mitigation tools include Berufshaftpflicht (professional liability insurance) and Betriebshaftpflicht (business liability insurance), both available from approximately €200/year for service businesses.
- Unlimited personal liability — all private assets exposed to business creditors
- No legal separation between business and personal estate (contrast GmbHG §13(2))
- Tax debts are personal debts — Finanzamt can seize private assets
- Berufshaftpflicht: essential for consultants, advisors, and regulated professions
- Betriebshaftpflicht: operational liability cover from ~€200/year
warning
Trade Name Rules Under HGB
A non-registered sole trader (Kleingewerbetreibender under HGB §1) must trade under their full legal name — first name and surname. Invented business names are not permitted. A sole trader who registers as eingetragener Kaufmann (e.K.) under §29 HGB may adopt a Firma (trade name) such as "Müller Consulting e.K." and gains full HGB merchant status. The e.K. registration at the Amtsgericht costs approximately €150–€300 in notary and court fees.
- Non-registered: must trade under full legal name — first and surname (HGB §17)
- No invented trade name without Handelsregister entry
- e.K. registration: unlocks Firma (trade name) and full HGB merchant status
- e.K. registration cost: ~€150–€300 (notary + Amtsgericht)
- Freiberufler: also must use personal name — no Firma without e.K. registration
Statutory Pension Obligation Under §2 SGB VI
Certain self-employed sole traders are subject to compulsory statutory pension insurance under §2 SGB VI regardless of personal preference. Affected groups include craftspeople (Handwerker), teachers and tutors, nurses and midwives, and artists and publicists via the Künstlersozialkasse (KSK). The KSK subsidises self-employed artists and journalists by covering the employer's share — so qualifying freelancers pay only approximately 20% of income rather than the full employee-plus-employer rate.
- §2 SGB VI: pension compulsory for craftspeople, teachers, nurses, certain artists
- KSK: covers 50% of SV contributions for qualifying artists and journalists
- KSK-eligible: writers, artists, musicians, designers, journalists, photographers
- KSK artist pays ~20% of income; KSK and publishers fund the remaining 50%
- Other self-employed: voluntary DRV contributions or private Rürup pension
VAT Options: Standard Rate and Kleinunternehmer
Sole traders are by default subject to Umsatzsteuer at 19% (or 7% for reduced-rate items under §12(2) UStG). Those with prior-year turnover ≤€22,000 and expected current-year turnover ≤€50,000 may elect the Kleinunternehmerregelung under §19 UStG, exempting them from charging VAT. This simplifies administration but eliminates Vorsteuer (input tax) reclaim. Businesses expecting significant equipment purchases usually opt into standard VAT from inception, as the Vorsteuer reclaim offsets the administrative overhead.
- Standard USt: 19% (7% for food, books, public transport, cultural services)
- §19 UStG Kleinunternehmer: prior-year ≤€22,000 AND current-year ≤€50,000
- Kleinunternehmer: no VAT charged, no VAT return, no Vorsteuer reclaim
- Standard VAT: quarterly Voranmeldung required (monthly in first 2 years)
- Opting into standard VAT: binding for 5 years under §19(2) UStG
Converting a Sole Proprietorship to a GmbH
The most tax-efficient conversion route is Einbringung under §20 UmwStG — contributing business assets and liabilities to a new GmbH at book value (Buchwertfortführung) without triggering capital gains tax. This requires a contribution agreement, a Steuerberater to structure the transaction, and a notarised GmbH Gesellschaftsvertrag. The GmbH inherits the same assets and trade history. Total conversion costs including notary, Amtsgericht, and advisory fees typically run €2,000–€5,000 plus the €25,000 share capital.
- §20 UmwStG: Einbringung at book value — tax-neutral if structured correctly
- Alternative: new GmbH founded and assets transferred commercially
- Client contracts: require consent under §613 BGB unless Vertragsübernahme agreed
- GmbH formation: notary + Amtsgericht cost ~€600–€1,000 plus €25,000 capital
- Total Einbringung cost: €1,500–€4,000 Steuerberater + notary fees
Frequently Asked Questions
What is the difference between a Gewerbetreibender and a Freiberufler?
A Gewerbetreibender (§15 EStG) must register a Gewerbe, join the IHK, and pay Gewerbesteuer. A Freiberufler (§18 EStG) — covering doctors, lawyers, architects, engineers, journalists, and qualifying IT consultants — registers only with the Finanzamt and is exempt from Gewerbesteuer and IHK.
How do I register as a Freiberufler in Germany?
Submit the §138 AO Fragebogen zur steuerlichen Erfassung to your local Finanzamt. No Gewerbeanmeldung, notary, or Handelsregister entry is needed. The Finanzamt assigns a Steuernummer within ~4 weeks. You cannot issue invoices until this number is received.
What is the Gewerbesteuer Freibetrag for sole traders?
Commercial sole traders pay Gewerbesteuer only on earnings above €24,500/year (GewStG §11(1)). At the average Hebesatz of ~400%, the effective rate is ~14% above that threshold. Gewerbesteuer paid is then offset against personal Einkommensteuer under EStG §35, largely eliminating double taxation.
What is the EÜR and who can use it?
The Einnahmen-Überschuss-Rechnung (§4(3) EStG) is simplified cash-basis accounting for sole traders with turnover <€600,000 and profit <€60,000. No balance sheet required — income minus expenses, filed as Anlage EÜR. Steuerberater fees are significantly lower than for a GmbH.
Are Freiberufler exempt from Gewerbesteuer?
Yes. Services classified under §18 EStG as freiberufliche Tätigkeit are fully exempt from Gewerbesteuer. This covers doctors, lawyers, architects, engineers, journalists, artists, teachers, and IT consultants doing creative or analytical work — one of the key advantages of Freiberufler status.
What assets can creditors seize from a German sole trader?
All personal assets — savings, real estate, vehicles, future income — are exposed. There is no business/personal separation. Only §811 ZPO items (essential household goods, basic tools) are exempt. This liability risk is the main reason growing sole traders convert to a GmbH.
What is the Kleinunternehmerregelung and should I use it?
§19 UStG exempts businesses with prior-year turnover ≤€22,000 and current-year ≤€50,000 from charging VAT. No quarterly VAT returns, no Vorsteuer reclaim. Businesses expecting significant equipment purchases usually prefer standard VAT from the start to reclaim input tax.
Which sole traders must pay statutory pension in Germany?
Under §2 SGB VI, compulsory pension applies to craftspeople, teachers, nurses, and artists/publicists via KSK. The KSK covers the employer's 50% share for qualifying artists — so they pay only ~20% of income. Other self-employed persons may contribute voluntarily to the DRV.
Can I use a business name as a non-registered sole trader?
No. Under HGB §17, non-registered sole traders must trade under their full legal name. To use a Firma (trade name), you must register as eingetragener Kaufmann (e.K.) under §29 HGB — costs ~€150–€300 at the Amtsgericht, plus full HGB merchant status.
What is the Künstlersozialkasse (KSK) and who qualifies?
The KSK covers 50% of pension, health, and nursing care contributions for self-employed artists and journalists — the artist pays only ~20% of income. Eligible: writers, artists, musicians, designers, photographers, journalists. A portfolio confirming artistic work as primary occupation is required.
When should I convert my sole proprietorship to a GmbH?
Typically when annual profit consistently exceeds €80,000–€100,000 (GmbH corporate tax 15% + ~14% GewSt beats up to 45% personal income tax), when liability exposure becomes material, or when you need equity investors or to hire staff at scale.
What is an Einbringung and how does it work?
Einbringung (§20 UmwStG) is the tax-neutral contribution of sole trader assets into a new GmbH at book value — avoiding capital gains tax on the transfer. A Steuerberater must structure the deal; a notarised GmbH Gesellschaftsvertrag is required. Total cost: ~€2,000–€5,000 plus €25,000 capital.
Does a Gewerbetreibender automatically become an IHK member?
Yes. Registering a Gewerbe triggers automatic compulsory IHK membership under §2 IHKG. Annual contributions are income-based, starting at €0 for early-stage businesses with low profit. The IHK provides advisory services, training, and business plan assessments. Freiberufler are not IHK members.
What income tax rate applies to a German sole trader?
Income from §15 EStG (commercial) or §18 EStG (freelance) is taxed at progressive Einkommensteuer rates: 0% up to the €11,784 Grundfreibetrag (2024), 42% above €66,761, and 45% Reichsteuer above €277,826. Solidarity surcharge is abolished for most taxpayers since 2021.
Can a foreign national start a sole proprietorship in Germany?
EU/EEA nationals may register freely. Non-EU nationals need a residence permit for self-employment — typically §21 AufenthG for founders or §18b AufenthG for qualified professionals. The permit must explicitly authorise the activity. Working without it risks fines and loss of residence status.
