Start or Buy a Business in Germany — Comprehensive Guide

Start New vs Buy Existing — Decision Framework

The choice between founding a new GmbH and acquiring an existing German business is primarily a trade-off between speed and risk. A new GmbH under GmbHG §§1–12 takes 3–6 weeks to incorporate and costs €1,500–3,000 all-in (notary, court, Handelsregister). Buying an existing Unternehmen can close in 4–12 weeks but requires €5,000–50,000+ in legal and due diligence fees before closing.

Forming a New GmbH — Legal Requirements (GmbHG §§1–12)

A GmbH (Gesellschaft mit beschränkter Haftung) is Germany's most common company form for SMEs. Formation requires a minimum Stammkapital (share capital) of €25,000 under GmbHG §5, of which at least €12,500 must be paid in cash before registration. The Gesellschaftsvertrag (articles of association) must be notarised. From notary appointment to Handelsregister entry the process typically takes 3–6 weeks and costs €1,500–3,000 total.

• Minimum share capital: €25,000 (GmbHG §5); at least €12,500 paid in before registration
• Notarised Gesellschaftsvertrag mandatory — notary fee approx. €500–800 depending on capital
• Handelsregister court fee: €150 for capital up to €30,000
• One managing director (Geschäftsführer) required — may be a foreign national
• Timeline: notary appointment → Handelsregister entry: 3–6 weeks
• Total formation cost all-in: €1,500–3,000 (notary + court + professional advisory)

German Business Acquisition Structures — Asset Deal vs Share Deal

Two structures dominate German M&A. In an asset deal, specific assets, contracts, and IP are transferred individually — historical GmbH liabilities remain with the seller's entity. In a share deal, the buyer acquires the GmbH shares under §15 GmbHG, inheriting the entire legal entity including all past liabilities, open tax assessments, and litigation. Asset deals are preferred by buyers; share deals are preferred by sellers for capital-gains tax efficiency.

• Asset deal: individual asset transfers, VAT treatment governed by §1(1a) UStG — full business transfer exempt from VAT if going concern
• Share deal (GmbH): share transfer (Abtretung von Geschäftsanteilen) requires notarisation under §15(3) GmbHG — legally void without notary
• Share deal risk: Finanzamt can assess additional taxes up to 10 years back (§169(2) AO)
• Updated Gesellschafterliste (shareholder register) must be filed with Handelsregister within 3 months of transfer
• W&I (warranty and indemnity) insurance is standard practice for deals above €2M to cap seller liability

Due Diligence Checklist (Unternehmenskauf)

A structured due diligence process protects buyers from post-closing surprises. For a German SME acquisition, four workstreams are standard. The Handelsregisterauszug (commercial register extract) is the first document to obtain — it confirms legal status, management, registered capital, and encumbrances (Grundpfandrechte). Jahresabschlüsse for the last 3 years reveal financial trends, hidden reserves, and off-balance-sheet obligations.

• Handelsregisterauszug: confirms legal status, management powers, share ownership, registered charges
• Jahresabschlüsse (3 years): HGB financial statements — check for hidden liabilities, pension provisions (§249 HGB), and related-party transactions
• Tax compliance: all filed tax returns, open Betriebsprüfungen (audits), transfer pricing documentation, VAT position
• Employment contracts: all Arbeitsverträge, Tarifvertrag (CBA) obligations, Betriebsrat (works council) agreements, pension obligations
• IP ownership: trademark registrations (DPMA), patent assignments, software licences — confirm seller actually owns IP being transferred
• Pending litigation: check Amtsgericht and Landgericht records; ask for disclosure of all claims above €10,000
• Environmental liabilities: land contamination (Altlasten) under BBodSchG — particularly relevant for manufacturing acquisitions

Company Valuation Methods (Bewertung)

German business valuation follows IDW S1 (Institut der Wirtschaftsprüfer Standard 1) for formal appraisals. For SME transactions, EBITDA multiples are the dominant market convention. EBITDA multiples for German SMEs typically range from 4–8x depending on sector, growth rate, and market position. Professional services firms trade at 4–6x; manufacturing at 5–8x; SaaS software at 10–20x ARR.

• EBITDA multiple method: most common for SME M&A — 4–8x EBITDA for traditional businesses, higher for tech
• Ertragswertverfahren (IDW S1): capitalised earnings method — standard for German courts and formal valuations
• DCF (Discounted Cash Flow): used alongside EBITDA multiples for larger transactions or growth companies
• Net asset value (Substanzwertverfahren): used as floor valuation for asset-heavy businesses (real estate, machinery)
• Micro-businesses (<€500K turnover): often priced at 1–2× annual turnover rather than EBITDA

Acquisition Financing Options

German acquisition finance combines bank debt, government-subsidised KfW loans, and vendor finance. KfW ERP-Kapital für Gründung provides subsidised loans from €25,000 for business acquisitions at below-market interest rates. Hausbank (main bank) credit typically covers 50–70% of purchase price. Mezzanine financing (subordinated debt) bridges the gap between bank debt and equity.

• KfW ERP-Gründerkredit Universell: subsidised bank loan, from €25,000, available to non-EU buyers with German entity
• Hausbank acquisition loan: typically 50–70% LTV on verified asset value or sustainable cash flows
• Vendor loan (Verkäuferdarlehen): seller finances 10–30% of price — aligns incentives, common in Mittelstand succession deals
• Mezzanine (e.g. Bayerische Beteiligungsgesellschaft): subordinated debt, higher rate, no security — typically 10–20% of deal
• KfW loans applied for through Hausbank (Hausbankprinzip) — KfW does not lend directly to borrowers

GmbH Share Transfer — Notarial Requirements (§15 GmbHG)

GmbH share transfers in Germany are strictly formal. Under §15(3) GmbHG, any agreement to transfer or assign GmbH Geschäftsanteile (shares) must be notarised (beurkundungspflichtig). A privately signed share purchase agreement is legally void — not merely unenforceable but without legal effect. The notary also files the updated Gesellschafterliste (shareholder list) with the Handelsregister. This makes GmbH share deals slightly slower than AG share deals but provides strong title security.

• §15(3) GmbHG: share transfer agreements must be notarised — no exception for small deals
• The Abtretungsvertrag (assignment agreement) and the Gesellschaftsvertrag amendment are typically combined in one notarial deed
• Notary fee for share transfer: typically €500–2,000 depending on transaction value
• Updated Gesellschafterliste: must be filed by the notary with the Handelsregister within 3 months
• Economic ownership (wirtschaftliches Eigentum) vs legal ownership: SPA may grant economic rights before notary signing; legal transfer only on notarisation

Share Purchase Agreement (SPA) — Key Clauses

The SPA (Unternehmenskaufvertrag) governs the entire transaction. German SPAs are typically governed by German law (BGB/HGB) and are notarised for GmbH share deals. Key clauses protect the buyer against undisclosed liabilities and ensure clear transfer of economic benefits from the agreed reference date (Stichtag). German-law SPAs tend to use locked-box mechanisms (fixed price based on historical accounts) rather than completion accounts.

• Purchase price adjustment mechanism: locked-box (most common in German M&A) or completion accounts
• Representations and warranties (Garantien): seller guarantees on financial statements, tax compliance, litigation, IP ownership
• Limitation periods: tax warranties typically 7 years (aligned with §169(2) AO); general warranties 2–3 years
• MAC clause (Material Adverse Change): triggers buyer's right to walk away if target deteriorates before closing
• Non-compete (Wettbewerbsverbot): seller typically restricted from competing for 2–3 years in same market and geography
• Condition precedent: Bundeskartellamt clearance if applicable; regulatory approvals (e.g. BaFin for financial services)

Employment Law in Business Acquisitions (§613a BGB)

When buying the assets of a German business with employees, §613a BGB (Betriebsübergang) automatically transfers all employment contracts to the buyer with unchanged terms — salaries, seniority, notice periods, and CBA agreements all carry over. Employees must be individually notified and have a one-month right to object. The works council (Betriebsrat), if present, must be formally consulted before the transfer.

• §613a BGB applies to asset deals transferring a business as a going concern (Betriebsübergang)
• All employment contracts transfer automatically — no re-hiring or new contracts required
• Employees retain all accrued seniority and statutory rights — no reset of notice period or vacation entitlement
• Individual notification letter required — employees have 1-month right to object and remain with seller
• Betriebsrat (works council) consultation mandatory before completion — failure to consult is an Ordnungswidrigkeit

Post-Acquisition Integration Checklist

Closing the transaction is the beginning, not the end. German post-acquisition integration requires attention to regulatory filings, banking relationships, and people management. Notify the Finanzamt (tax office) of the ownership change within one month. Update bank mandates, authorised signatory lists, and direct debit authorities. Communicate transparently with employees — German employment law and Betriebsrat influence means early, honest communication avoids works council disputes.

• Finanzamt notification: file updated ownership details within 1 month of closing
• Handelsregister update: if new Geschäftsführer appointed, register immediately — delays expose directors to personal liability
• Banking mandates: update all authorised signatories and SEPA direct debit mandates with Hausbank
• Insurance: review all existing policies — D&O, liability, property — and update named insured or add buyer as co-insured
• Customer and supplier notifications: review NDA and assignment clauses in key contracts before communicating change of ownership
• Betriebsrat engagement: schedule introductory meeting within first 2 weeks — German works council has information rights under §80 BetrVG
