UK Company France: Legal Guide to Setting Up a French Subsidiary

A UK company France expansion is often driven by strategic growth, EU market access, or post-Brexit operational restructuring.

Establishing a presence in France requires careful consideration of legal structure, taxation, corporate governance and employment law. Early decisions significantly affect long-term compliance and cost exposure.

This guide provides a clear and structured overview of the legal framework applicable when a UK company expands into France.

 

Why Establish a UK Company in France?

 

Access to the EU Market

France offers direct access to the European Union single market. For British companies, a French presence can facilitate:

• commercial credibility within the EU,

• streamlined supply chains,

• local invoicing and VAT structuring,

• proximity to European customers and partners.

Post-Brexit Strategic Considerations

 

Since Brexit, UK businesses have reassessed their European footprint. Establishing operations in France may help:

• mitigate customs and VAT complexity,

• secure EU-based contracts,

• simplify cross-border trade,

• maintain regulatory alignment within the EU framework.

In many cases, expansion aligns with broader corporate restructuring or cross-border growth strategies.

Market Trends and Corporate Expansion

 

Current trends include:

• operational subsidiaries to support EU sales,

• expansion tied to investment rounds,

• cross-border acquisitions,

• corporate reorganisations,

• and in some cases, cross-border mergers or fusions.

Each scenario requires tailored legal structuring.

Choosing the Right Legal Structure

Selecting the appropriate legal vehicle is central to a successful UK company France expansion.

French Subsidiary (SAS or SARL)

A common approach is to set up a French subsidiary (typically a SAS or SARL). This creates a separate legal entity under French law.

Advantages include:

• legal autonomy,

• clearer liability separation,

• enhanced credibility with French partners,

• easier recruitment and employment structuring.

From a corporate perspective, a subsidiary also facilitates future capital increases, equity participation, or cross-border mergers and fusions.

Branch (Succursale)

A branch does not create a separate legal personality. The UK parent company remains fully liable.

This structure may be appropriate for limited activity but requires careful analysis of permanent establishment and taxation implications.

Representative Office

A representative office is generally limited to non-commercial activities such as market research or liaison functions.

Once commercial transactions occur in France, a reassessment of the structure becomes necessary.

Common Structural Mistakes

Frequent errors include:

• replicating a UK legal structure without adaptation,

• failing to anticipate investor entry,

• underestimating French employment obligations,

• neglecting long-term corporate governance planning.

Structural decisions should align with growth projections and risk management.

UK Company Taxation France: Fiscal and Accounting Obligations

Tax and accounting obligations are often underestimated.

Corporate Taxation

A French entity is generally subject to French corporate income tax on profits generated in France.

Additional obligations may include:

• VAT registration and compliance,

• local business taxes,

• sector-specific contributions.

The precise tax treatment depends on the structure and operational model.

Employment Law France: Social Obligations

French employment law France is highly structured and protective.

Key obligations include:

• social security registration,

• payroll contributions,

• compliance with collective bargaining agreements,

• strict rules governing termination.

The overall employer cost in France is typically higher than in the UK and must be carefully budgeted.

Accounting Requirements

A French entity must maintain accounting records in accordance with French standards and file annual financial statements.

Failure to comply may result in financial penalties or reputational risk.

Legal Risks and Best Practices

High-Risk Areas

Common legal exposure arises from:

• non-compliant employment contracts,

• improper VAT treatment of cross-border transactions,

• contracts governed by inappropriate law,

• unclear corporate governance structures,

• lack of due diligence in acquisition scenarios.

In the context of acquisitions, mergers, or cross-border fusions, insufficient pre-transaction analysis significantly increases risk.

Recommended Best Practices

• Conduct a legal and tax feasibility study before incorporation.

• Align structure with medium-term corporate strategy.

• Review all commercial contracts under French law.

• Implement ongoing compliance monitoring.

• Coordinate between legal counsel, tax advisers and accountants.

An internal financial analyst may support financial modelling, but legal risk assessment remains essential.

When to Seek Legal Advice

Legal support is particularly advisable:

• before selecting the legal structure,

• prior to drafting articles of association,

• when negotiating key commercial contracts,

• during acquisition, restructuring or merger operations,

• when hiring employees in France.

A dual-qualified Franco-British lawyer can bridge legal differences between jurisdictions and ensure structural coherence.
