Practical Guide — Doing Business in Courbevoie / La Défense
Everything you need to know about doing business in Courbevoie / La Défense
Headquarters taxation and fiscal integration
Groups based in La Défense can optimize their taxation through the fiscal integration regime (Article 223 A of the French Tax Code). This mechanism allows offsetting subsidiary results: losses from some reduce profits from others. The 15% corporate tax rate on the first €100,000 of profit (2026 Finance Bill) strengthens attractiveness. We structure your group to maximize these savings.
R&D Tax Credit and innovation in La Défense
Startups and R&D centers in La Défense can benefit from the CIR (30% of research expenses up to €100M, 5% beyond). Eligible expenses include researcher and engineer salaries, depreciation of assets used for R&D, subcontracting to approved bodies, and flat-rate operating costs equal to 40% of staff costs plus 75% of those depreciation charges. Patent costs and technology watch, by contrast, were removed from the tax base by the 2025 Finance Act, for expenditure incurred from 15 February 2025. JEI status additionally provides a full exemption from employer social-security and family-allowance contributions on R&D staff, capped at €8,401.58 of gross monthly pay per employee and €240,300 per establishment per year. We secure your CIR file against tax authority audits.
Fundraising and capital structure
La Défense is a major fundraising hub. We support startups in structuring their funding rounds: pre-money valuation, BSPCE for employees, shareholders' agreements, accounting and financial due diligence. Our experts prepare your files for investors (VC, business angels, Bpifrance).
Corporate real estate and property optimization
Rents in La Défense range from €400 to €800/m²/year depending on the tower. The choice between a standard commercial lease, a derogatory lease (Article L. 252-1 of the Commercial Code) and office center domiciliation directly impacts your cash flow. We analyze the true cost of your location and optimize the deductibility of your property expenses.
Frequently asked questions — Chartered accountant in Courbevoie / La Défense
Answers to questions entrepreneurs in Courbevoie / La Défense ask most
How much does a chartered accountant cost in Courbevoie / La Défense?
Fees vary based on the size and complexity of your structure. For a micro-enterprise: €50-100/month. For a SAS with 10 employees: €300-600/month. For a group subsidiary with consolidation: €800-2,000/month. Our firm offers transparent flat rates tailored to La Défense businesses.
What support is available for startups in La Défense?
Several programs exist: the R&D Tax Credit (30% of eligible R&D spend up to €100M, 5% beyond), JEI status (full exemption from the employer social-security and family-allowance contributions due on staff assigned to R&D, with the other contributions still payable: workplace-accident, unemployment, supplementary pension, CSG/CRDS), the Innovation Tax Credit for SMEs (20% of expenses, base capped at €400,000 per year), Bpifrance aid (seed loans, innovation grants), and Greater Paris programs (Def'Hub, incubators). We identify eligible aid and support your applications.
Can you manage the accounting of my French subsidiary from abroad?
Absolutely. Our firm supports many foreign group subsidiaries based in La Défense. We handle all your French obligations (accounting, tax returns, VAT, payroll, CSE) and provide reporting in your parent company's language.
Which legal structure should I choose for my La Défense headquarters?
The SAS is the most common form for subsidiaries and startups in La Défense due to its statutory flexibility and compatibility with international investors. The SARL suits family SMEs. We analyze your situation (number of shareholders, planned fundraising, governance) to recommend the optimal structure.
How can I optimize my group's taxation in La Défense?
Fiscal integration is the main lever: it allows offsetting subsidiary results. The mother-daughter regime reduces taxation on dividends remitted to the holding company (1.25% effective). Transfer pricing secures intra-group transactions. Our experts model your structure and identify compliant optimizations.
