France

France offers a comprehensive tax and social contribution system for equity compensation. Understanding French tax obligations is essential for tech professionals receiving stock options and RSUs, especially given high marginal rates and social contributions.

Overview of French Tax System

France has a progressive tax system with:

• Income Tax (Impôt sur le Revenu) on employment income
• Social Contributions (CSG/CRDS) on all income
• Capital Gains Tax on share sales
• Progressive rates up to 45% plus social contributions

RSU Taxation

At Vesting

RSUs are taxed as employment income when they vest:

Income Tax Rates (2025)

Social Contributions (CSG/CRDS)

• CSG (Contribution Sociale Généralisée): 9.2%
• CRDS (Contribution au Remboursement de la Dette Sociale): 0.5%
• Total: 9.7% on all income (including RSU vesting)

Example Calculation

Employee vests €100,000 in RSUs:

Income Tax (45%): €100,000 × 45% = €45,000
CSG/CRDS: €100,000 × 9.7% = €9,700
Social Security: ~€23,000
Total Tax: ~€77,700
Net: ~€22,300

At Sale

Note: Capital gains on securities are taxed as income, not at a flat rate.

Stock Options

• Stay within €300,000 benefit limit
• Coordinate multiple grants

Capital Gains Optimization

• Hold shares >2 years for 50% abattement
• Consider timing of sales
• Utilize lower brackets where possible

PEA (Plan d'Épargne en Actions)

• Tax-advantaged investment account
• After 5 years: No tax on gains
• Annual contribution limit: €150,000
• Useful for holding employer shares

Practical Examples

Example 1: RSU Vesting

Employee vests €120,000 in RSUs:

Income Tax (45%): €120,000 × 45% = €54,000
CSG/CRDS: €120,000 × 9.7% = €11,640
Social Security: ~€27,600
Total Tax: ~€93,240
Net: ~€26,760

Example 2: BSPCE with Exemption

Employee exercises BSPCE options after 4 years:

Exercise: No tax (BSPCE benefit)
Sale Gain: €60,000
Abattement (50%): €60,000 × 50% = €30,000
Taxable Gain: €30,000
Tax (30%): €30,000 × 30% = €9,000
CSG/CRDS: €30,000 × 9.7% = €2,910
Total Tax: €11,910
Effective Rate: 19.85%
