A foreign company has a permanent establishment in Germany when it maintains a fixed place of business in the country, runs a construction or installation project that exceeds the time limit in the applicable tax treaty, or uses a dependent agent who habitually signs contracts on its behalf. Once any of those triggers is met, Germany taxes the profits attributable to the German operation at a combined corporate and trade tax rate that typically lands between 30% and 33%, and a set of registration, payroll, and documentation duties kicks in immediately.
Getting the analysis wrong is expensive. Companies that discover a PE retroactively often face years of unfiled returns, estimated assessments at the top of a plausible range, and compounding interest and penalties.
What Counts as a Permanent Establishment
Two legal frameworks run in parallel. German domestic law defines a PE under Section 12 of the General Fiscal Code (Abgabenordnung) as any fixed place of business through which a company carries on its operations, with examples including a place of management, branch, office, warehouse, or workshop. Section 13 AO separately captures a “permanent representative,” meaning a person who habitually acts on behalf of a foreign principal.
The second framework is the applicable double taxation treaty between Germany and the company’s home country. Germany’s treaties largely follow the OECD Model Tax Convention. Where the treaty produces a more favorable result for the taxpayer, it takes precedence over domestic law. A short-lived facility that domestic law would treat as a PE, for instance, may be excluded because the treaty sets a higher threshold.
For a fixed-place PE, three conditions must all be met: the location must be geographically fixed, it must last long enough to show permanence, and the company must carry on actual business activities there. Germany’s Federal Fiscal Court has confirmed that the minimum duration is generally six months of both a fixed place and active operations at that location.1Deloitte tax@hand. Federal Tax Court Decisions Clarify Conditions for a Permanent Establishment
Fixed Place of Business
The most common trigger is a physical location in Germany from which the foreign company conducts operations. Branch offices, factories, and workshops are the obvious examples. Less obvious ones include a dedicated desk inside a client’s building or a rented storage facility used to fill customer orders.
The critical concept is Verfügungsmacht, or power of disposal. The foreign company must have the right to use the premises as its own, not just visit occasionally. Meetings held periodically at a client’s office do not satisfy the test. A designated workspace reserved for the company’s employees on a sustained basis probably does.
The same question comes up in co-working and shared-space arrangements. A fixed, identifiable area the company controls and can exclude others from is generally enough. Rotating employees through generic hot desks with no reserved space is a weaker case. German tax authorities look at the practical reality of who controls the space, not just what the lease says.
Construction and Installation Projects
Construction and installation projects follow a special rule. They create a PE only if they last longer than the time threshold set in the applicable treaty. Under the OECD Model Convention that threshold is twelve months.2OECD. The 2025 Update to the OECD Model Tax Convention Most of Germany’s bilateral treaties stick to the twelve-month standard, but a handful use shorter periods, so the specific treaty always needs to be checked.
The clock starts earlier than most companies expect. Preparatory work at the site, such as surveying or setting up temporary structures, counts toward the threshold. Brief interruptions for holidays, weather, or supply shortages do not stop the clock. Tax offices look at the continuous commercial connection to the site, not whether work was happening every day.
Related projects in the same area can be aggregated. Two consecutive installation jobs run by the same company at the same factory campus may be treated as a single project for threshold purposes if they are commercially and geographically connected, regardless of separate contract numbers.
Dependent Agents
A foreign company can trigger a PE through the activities of a person acting on its behalf in Germany, even with no office at all. The trigger is whether the agent habitually exercises authority to conclude contracts in the company’s name.
The agent must also be economically dependent on the foreign company. Signs of dependence include the foreign company controlling the agent’s daily activities, bearing the commercial risk of the transactions, and providing detailed instructions on how the work is done. If the agent’s economic activity is substantially devoted to one foreign principal, dependence is generally presumed. An independent agent acting in the ordinary course of their own business, bearing their own commercial risk, and maintaining legal and economic autonomy does not create a PE.
Germany’s Narrower Standard
The 2017 update to the OECD Model Convention broadened the dependent-agent concept to also cover agents who play the “principal role” leading to contract conclusions, even without formal signing authority, and it targeted commissionaire arrangements where an intermediary contracts in its own name but on behalf of the foreign company.
Germany has explicitly reserved against both changes. It retains the right to apply the pre-2017 version of the rule, limiting it to agents who habitually exercise authority to conclude contracts in the enterprise’s name.2OECD. The 2025 Update to the OECD Model Tax Convention Germany also rejects the rule that an agent acting exclusively for closely related enterprises automatically loses independent status. In treaty terms, Germany’s standard is narrower than what many other OECD countries now apply.
Domestic law under Section 13 AO can still capture some arrangements that fall outside the treaty definition. A company relying on a commissionaire structure in Germany should not assume it is safe just because the treaty uses the older standard. Where domestic law creates a broader PE than the treaty, the treaty will usually shield the taxpayer, but both frameworks need to be examined.
Activities That Don’t Create a PE
Not every physical presence triggers a PE. Treaties and the OECD Model exclude activities that are purely preparatory or auxiliary to the company’s main business. Common examples: a warehouse used solely to store goods before they are shipped elsewhere, a purchasing office that buys raw materials for the head office, or a facility for collecting market research.
German tax authorities read these exclusions strictly. The question is whether the activity forms a significant and essential part of the overall business, or whether it merely supports operations happening elsewhere. A warehouse that only stores inventory for a manufacturer abroad is likely auxiliary. A warehouse that processes, packages, and ships products directly to German customers probably is not.
The Anti-Fragmentation Rule
Following BEPS Action 7, the OECD introduced an anti-fragmentation rule to stop companies from splitting complementary activities across multiple locations to keep each one below the preparatory/auxiliary threshold. The exception no longer applies if the same company, or a closely related one, carries on business at the same or another place in Germany and the combined activities form a cohesive business operation that is not preparatory or auxiliary when viewed as a whole.3OECD. Preventing the Artificial Avoidance of Permanent Establishment Status, Action 7 – 2015 Final Report A “customer support center” in one building and a “logistics hub” next door, both feeding the same German sales operation, cannot each be defended as merely auxiliary just because neither alone looks like a full business.
Home Office and Remote Work
Since the pandemic the question comes up constantly: does an employee working from home in Germany create a PE for their foreign employer? For ordinary employees, the answer from German tax authorities is generally no.
A February 2024 administrative guidance letter from the Federal Ministry of Finance confirmed that home office activities by ordinary employees do not create a PE under domestic law or under tax treaties. This holds even if the employer pays for the home office setup, even if there is a formal lease between employer and employee for the space, and even if the employer provides no alternative office. In each case the employer lacks sufficient power of disposal over the employee’s private home.
The exception is employees who exercise management functions. If a senior executive makes strategic decisions for the company from a home office in Germany, the tax authorities may find that those management activities give the employer enough constructive control over the space to trigger a PE. The distinction matters for companies with C-suite executives or country managers working remotely from Germany.
The Tax Bill Once a PE Exists
A PE brings three layers of German tax on the profits earned through it.
Corporate Income Tax and Solidarity Surcharge
Corporate income tax applies at a flat 15% on the PE’s taxable income.4Germany Trade & Invest. Corporate Taxation in Germany A solidarity surcharge of 5.5% is levied on the corporate income tax amount itself, adding roughly 0.8 percentage points. The effective federal rate lands at about 15.825%.
Trade Tax
Trade tax (Gewerbesteuer) is a local tax that varies by municipality. The PE’s adjusted business income is multiplied by a uniform national base rate of 3.5%, and that result is multiplied by the municipal multiplier (Hebesatz) set by the city or town where the PE is located.5Germany Trade & Invest. Trade Tax The multiplier cannot fall below 200%, so the effective floor is 7%. The national average sits slightly above 14%. In municipalities of at least 80,000 residents, trade tax rates run from about 8.75% to 20.3%.
Adding everything together, the overall burden on PE profits in a major German city typically lands between 30% and 33%. Frankfurt comes in around 32%, Berlin around 30%, and Munich around 33%.6PwC Worldwide Tax Summaries.

How Much Profit Germany Actually Taxes
Only the profits fairly attributable to the German operations are taxed, not the foreign company’s worldwide income. The attribution follows the Authorized OECD Approach (AOA), which Germany has incorporated through Section 1(5) of the Foreign Tax Act (Außensteuergesetz) and a separate profit allocation ordinance.7Federal Ministry of Finance. Ordinance on the Allocation of Profits of Permanent Establishments
The AOA treats the PE as if it were a separate, independent enterprise conducting arm’s-length transactions with the head office. The exercise starts with a functional and risk analysis identifying what the PE’s employees actually do, what assets are deployed in Germany, and what risks the German operation bears. Free capital is then attributed to the PE to support its risk profile, and transfer pricing methods are applied to all dealings between the PE and the rest of the company.8KPMG. Germany Legislation Incorporating Authorized OECD Approach to PEs Not an Independent Rule for Determining PE Profit
Registration, Filing, and Payroll Duties
Once a PE is confirmed, a cascade of registration requirements follows. The company must obtain a German tax number (Steuernummer) from the local tax office (Finanzamt) where the PE sits. The PE must register its commercial activity with the local trade office, which triggers trade tax liability and automatically notifies the Finanzamt. If the PE makes taxable supplies of goods or services in Germany, a separate VAT registration and a VAT Identification Number for intra-EU transactions are needed.
Annual corporate income tax and trade tax returns must be filed with the Finanzamt, reporting the profits attributable to the German operations. Books and records must comply with German accounting standards (GoBD) and be kept in Germany or accessible from Germany. Retention periods are long: ten years for trading books, opening balance sheets, annual financial statements, and related organizational documents; eight years for accounting documents such as invoices (reduced from ten by the Fourth Bureaucracy Relief Act effective January 2025); and six years for commercial correspondence. The clock starts at the end of the calendar year in which the document was created or received.
Wage Tax Withholding
A foreign employer with a PE in Germany counts as a “domestic employer” for payroll tax purposes. The company must withhold income tax (Lohnsteuer) from employees’ wages, submit electronic payroll tax registrations to the tax office, and remit withheld amounts on time. Failure to withhold does not relieve the employer of its withholding obligations or possible penalties, even if the employees end up paying the tax themselves through annual assessment.
Social Security Contributions
Employees working at a German PE are generally subject to German social security. In 2026, the employer’s share includes pension insurance at 9.3%, unemployment insurance at 1.3%, health insurance at 7.3% plus half the fund-specific additional contribution (averaging about 1.45%), and long-term care insurance at 1.7%.9PwC Worldwide Tax Summaries. Germany – Individual – Other Taxes These apply up to income ceilings that vary by insurance type. The combined employer burden adds roughly 20% to 21% on top of gross wages, a cost that catches many foreign companies off guard when budgeting for German operations.
Transfer Pricing Documentation
Transactions between the PE and its head office must be documented as if they were dealings between unrelated parties. German law requires transfer pricing documentation for all cross-border transactions with related parties, and this explicitly includes dealings between a PE and the rest of the enterprise.10Federal Ministry of Finance. Administrative Principles Governing Transfer Pricing
Documentation must explain the factual circumstances of each transaction, the economic rationale, and the transfer pricing method used to establish arm’s-length pricing. Under current rules, taxpayers must produce this documentation within 30 days of the start of a tax audit, without waiting for a specific request from the auditor. For exceptional transactions such as restructurings, the deadline is even shorter.
Small-scale operations get some relief. If total consideration for intercompany goods deliveries stays below EUR 6 million and all other intercompany transactions stay below EUR 600,000 per year, simplified documentation rules apply. Exceeding either threshold in the prior year eliminates the relief for the current year.
Penalties for Getting It Wrong
If a company fails to file returns or maintain proper records, the tax office can estimate the PE’s taxable income under Section 162 of the Fiscal Code. Estimates tend to be unfavorable. The tax office is explicitly allowed to select the upper end of any plausible income range when the taxpayer has failed to cooperate, and the burden of proving the estimate is too high shifts to the taxpayer.11Federal Ministry of Finance. Estimating Tax Bases – Section 162
Late returns trigger a surcharge of 0.25% of the assessed tax per month (or part of a month) of delay, with a minimum of EUR 25 per month and a cap of EUR 25,000 per return. Interest accrues on any unpaid balance.
Failing to produce transfer pricing documentation carries a penalty of at least EUR 5,000 per undocumented transaction. If the missing documentation leads to an income adjustment, the penalty rises to between 5% and 10% of the additional income assessed. Submitting documentation late, after the deadline but before the audit concludes, incurs penalties of at least EUR 100 per day, up to EUR 1 million.11Federal Ministry of Finance. Estimating Tax Bases – Section 162
The combination of estimated assessments, surcharges, and documentation penalties can produce a tax bill much larger than proper compliance would have cost. A company that discovers a PE retroactively can face several years of unfiled returns with compounding interest, which is why the PE analysis pays to get right at the outset.
