Managing Internationally Mobile Employees

Managing internationally mobile employees requires proactive planning, continuous monitoring and regulatory compliance throughout the assignment lifecycle.

Employers must address multiple factors, including:

• Mobility policy design and implementation
• International travel and assignment planning
• Payroll and tax compliance
• Employee support and communication
• Regulatory monitoring across jurisdictions

As global mobility rules continue to evolve, RSM Switzerland assists organisations in establishing and managing effective mobility programmes while ensuring compliance with tax, social security, pension, immigration, legal and data protection requirements.

Through the RSM global network, we deliver coordinated advice across jurisdictions, supported by strong Swiss regulatory expertise.

Tax Advisory for Employers and Internationally Mobile Employees

Our global mobility tax advisory services in Switzerland help employers and employees remain compliant with Swiss and international tax regulations while mitigating double taxation risks and potential corporate tax exposure abroad.

We support both organisations and employees throughout the entire international assignment lifecycle, including:

• International tax planning and structuring
• Pre-assignment and pre-hiring tax assessments
• Arrival and departure tax briefings
• Hypothetical tax calculations and reconciliations
• Communication and negotiations with tax authorities
• Preparation and filing of Swiss individual tax returns

In a rapidly evolving international tax environment, proactive advisory and monitoring are essential. Our specialists provide strategic insights beyond compliance, helping businesses anticipate risks and optimise tax outcomes.

Social Security and Pension Advisory

Cross-border employment often creates complex social security and pension obligations due to significant differences between national systems.

Ensuring the correct social security coverage in Switzerland, the EU or other jurisdictions is essential to maintain compliance and protect employee benefits.

RSM Switzerland provides specialised expertise in Swiss, EU and international social security coordination, supporting employers with:

• Determining applicable social security regimes
• Managing A1 certificates and coverage documentation
• Coordinating cross-border benefit entitlements
• Optimising pension and benefit structures

We also advise companies on tax-efficient pension and benefit plans, supporting talent attraction and retention while balancing cost and benefit considerations.

Compensation and Long-Term Incentive Plans

A competitive and well-structured compensation framework is essential for attracting, motivating and retaining international talent.

We assist organisations in designing and implementing compensation structures and long-term incentive plans (LTIPs) aligned with corporate strategy and performance objectives.

Our services include:

• Compensation benchmarking
• Equity and share-based incentive plans
• Tax-efficient remuneration structures
• Cross-border compensation planning

We ensure that compensation arrangements remain legally compliant and tax-efficient, particularly in international and cross-border employment scenarios.

Immigration and Human Resources Advisory

Leveraging our Swiss expertise and international network, we support organisations with:

• Global mobility policies
• International payroll coordination
• HR compliance advisory

We also assist employers and employees with immigration processes in Switzerland, including:

• Work permits
• Residence permits
