Global Stock Option Taxation for European Expats 2025

Equity compensation remains a cornerstone of global mobility packages. In 2025, European expats must navigate complex sourcing rules, vesting taxation, and double taxation relief when moving between countries.

Key Considerations

• Source Allocation: Tax authorities allocate gains based on workdays between grant and vest. Maintain mobility calendars to substantiate allocations.
• Reporting: Some countries (e.g., France, Spain) require employer reporting of cross-border equity events; ensure payroll and tax teams coordinate.
• Double Tax Relief: Use treaty provisions and foreign tax credits to avoid being taxed twice, especially when vesting spans multiple jurisdictions.

Best Practices

Provide expats with annual equity summaries, offer gross-up support for compliance costs, and review hypothecation policies under tax equalisation programmes. Consider local withholding obligations to prevent penalties.

Outcome: Structured equity governance elevates expat experience while mitigating cross-border tax risks.
