The Permanent Establishment Trap: Tax Risk When Your First Sales Hire Sits in Germany

The first German hire is usually celebrated as a commercial milestone. For the tax department, it is the moment a foreign company may acquire a taxable presence in Germany without ever registering anything. The concept is called a permanent establishment, and it is one of the most underestimated risks of an asset-light market entry.

A permanent establishment (PE) means that part of the foreign company's profits becomes taxable in Germany — with filing obligations, profit allocation, and the German tax burden on that share. It does not require a German entity, an office lease, or a single invoice issued from Germany. It can arise from how people work and what they are authorised to do.

Two Routes Into a Permanent Establishment

German domestic law and the double tax treaties Germany has concluded recognise two main triggers. Where a treaty applies, its narrower definition generally prevails — which makes the treaty with your home country the first document to read.

• Fixed place of business: an office, a co-working desk used permanently, or premises at the company's disposal from which business is carried on. The key questions are permanence and whether the place is actually at the company's disposal.
• Dependent agent: a person who habitually concludes contracts in the company's name — or, under modern treaty wording, habitually plays the principal role leading to contracts that are routinely concluded without material modification. A senior sales hire who negotiates and closes is the classic case. German domestic law goes further: a permanent representative (section 13 of the Fiscal Code, AO) is already anyone who habitually brokers contracts or solicits orders for the company — so without a treaty, withholding signing authority does not protect you.

The Home Office Question

A remote employee working from their German flat does not automatically create a PE. The analysis turns on whether the company actually has the home office at its disposal and how regularly business is carried on from there. In the view of the German tax administration (application decree to the Fiscal Code, the Abgabenordnung, and the Federal Ministry of Finance letter of 18 June 2026 on the PE concept), an employee's home office does not as a rule create a PE of the employer, because the employer lacks the power of disposal over the flat; where management functions are exercised there, however, a place-of-management PE can arise. The OECD refined its guidance on home offices in 2025: working from home for less than half of the working time for the company does not as a rule create a PE there; above that, one of the questions is whether there is a commercial reason for the activity in that country. Independently of this, a sales hire can create an agency PE from a home office as well — the combination of a home office with sales authority is where the risk concentrates.

Permanent establishments are rarely created by decisions. They are created by job descriptions, e-mail signatures, and signed contracts.

What a Permanent Establishment Costs

• Tax burden: profits attributable to the PE are subject to German corporate income tax plus solidarity surcharge and municipal trade tax — together typically around 30 percent. The corporate income tax rate is scheduled to fall step by step from 2028.
• Compliance: tax registration, annual returns, and a documented allocation of profits between head office and PE under the arm's-length principle.
• Retroactive discovery: PEs are often identified during tax audits or due diligence — with back taxes and interest for several years.
• Transaction friction: an unmanaged PE surfaces as a red flag in funding rounds and M&A due diligence.

Separate Obligations Not to Confuse

Two neighbouring regimes run independently of the PE question. Social security: employees working in Germany are generally subject to German social security, and the employer has registration and contribution duties even without any German entity. VAT: the VAT concept of a fixed establishment follows its own criteria and can change how invoices must be issued. A clean PE analysis does not settle either — which is why payroll and VAT deserve their own review.

Structuring the First Hires Safely

1. 01Define authority precisely: sales support, lead generation, and relationship management — but contract negotiation and signature at head office, documented in role descriptions and signature policies.
2. 02Avoid providing or requiring a fixed German workplace until you are ready to accept the PE consequences; if you rent space, assume a PE exists.
3. 03Check the applicable double tax treaty — the dependent-agent wording differs between treaties and decides borderline cases.
4. 04Consider a local subsidiary acting as a limited-risk distributor or service provider with a cost-plus remuneration: it creates a transparent, predictable German tax base instead of an undocumented PE risk.
5. 05Revisit the analysis as the team grows — the structure that fits two hires rarely fits ten.

Austria and Switzerland

The same concepts apply across the DACH region, with national nuances in domestic law and treaty networks. Austria's PE definition is close to the German one; Switzerland distinguishes clearly between fixed places of business and activities of a preparatory or auxiliary character. For multi-country teams, a single matrix — who works where, with which authority — is the most useful tax document you can maintain.

Conclusion

A permanent establishment is not a penalty; it is a tax status. The problem is creating it by accident, without documentation, and discovering it later. Companies that decide deliberately — PE, subsidiary, or tightly limited authority — enter the German market with predictable tax costs.
