A two-level issue, with stakes measured in millions
Permanent establishment is the turning point in the taxation of foreign companies operating in France. For VAT, it determines the territoriality of supplies of services (French Tax Code, art. 259 et seq): if the French structure receives and uses services for its own needs, the transactions fall within the scope of French VAT, with registration, reporting and deduction rights. For corporate income tax, the question is governed by article 209 of the French Tax Code and tax treaties (OECD model, art. 5 and 7): a fixed place of business or dependent agent with authority to bind the company, according to the reading adopted by the Council of State in the Conversant (ValueClick) case of 11 December 2020 (n° 420174).
On the VAT side, the CJEU has developed a stringent analytical framework through five rulings: Dong Yang (C-547/18), Titanium (C-931/19), Berlin Chemie (C-333/20), Cabot Plastics (C-232/22) and Adient (C-533/22). A VAT permanent establishment requires a permanent structure with human and technical resources, which need not be owned by the company but must be controlled 'as if they were its own', and which must allow it to receive and use services for its own needs. Reliance on a local service provider, even if exclusive, is not sufficient: the same resources cannot simultaneously serve both to provide the service and to receive it.
This framework concerns the customer-side permanent establishment, the one that receives the services. VAT is also at stake on the other side, that of the supplier-side permanent establishment, and it is there that the heaviest French assessments arise. For services falling under article 259, 1° of the French Tax Code, the tax is in principle accounted for by the French customer where the supplier is not established in France (French Tax Code, art. 283, 2). But a foreign company that has in France a structure with a sufficient degree of permanence and the human and technical resources enabling it to provide the services it supplies (Implementing Regulation (EU) No 282/2011, art. 11(2)), and that actually intervenes in the transaction — purely administrative support tasks, such as accounting or invoicing, not being enough to establish such intervention (same regulation, art. 53) — is not regarded, for the purpose of designating the person liable for the tax, as a taxable person established outside France (French Tax Code, art. 283-0). The reverse charge then no longer applies and the foreign company accounts for French VAT itself. That is precisely the ground on which VAT was assessed in the Conversant case: the Council of State held that, having a permanent establishment in France, the Irish company 'was solely liable for value added tax' (Council of State, 4 April 2025, n° 461220 and 461310).
The financial scale justifies rigorous upstream analysis. When a permanent establishment is characterised retrospectively by the tax authority, the activity is frequently treated as undeclared: the statute of limitations extends to ten years (French Tax Procedure Code, art. L. 169 for corporate income tax and art. L. 176 for VAT) and the resulting assessments for corporate income tax and VAT are subject to an 80% surcharge (French Tax Code, art. 1728, 1, c). For an international group, the cumulative exposure routinely reaches several million euros. This is precisely the type of case the firm handles, in French and English, from its offices in Paris and Geneva.
