International Tax Services
Clarity across jurisdictions. Confidence in every obligation.
Cross-border moves and international working arrangements can create tax obligations for both organisations and individuals. EMS provides practical guidance and coordinated support to help clients understand their position, navigate local and international requirements, and manage compliance throughout the mobility lifecycle.
Discuss your tax requirementsCross-border activity brings added tax complexity
An employee assignment, permanent transfer, remote-working arrangement or move between countries can affect where and how tax obligations arise. Requirements may differ by jurisdiction and can change as circumstances evolve. Without early assessment and coordinated follow-through, companies and mobile individuals may face uncertainty, duplicated effort and avoidable compliance risk.
What the service can include
Support is tailored to the client, the jurisdictions involved and the agreed engagement. It may include:
Cross-border tax assessment
Review the individual’s circumstances, mobility pattern and relevant jurisdictions to identify key tax considerations.
Arrival and departure guidance
Explain the principal tax implications associated with entering or leaving a country.
Tax briefings
Provide mobile employees and individuals with practical guidance on responsibilities, documents and anticipated timelines.
Compliance coordination
Coordinate required information and local specialist support for applicable registrations, declarations or filings.
Payroll and mobility coordination
Help align relevant tax information with payroll, HR, immigration and assignment processes.
Ongoing advisory
Respond to changes in assignment terms, working patterns or personal circumstances that may affect the tax position.
- HR and Global Mobility teams managing international assignments or transfers.
- Companies with employees working across borders or from new jurisdictions.
- RMCs seeking coordinated tax support within a broader mobility programme.
- Executives, employees, individuals and families moving internationally.
- An employee is beginning, extending or ending an international assignment.
- A company needs to understand the tax implications of a cross-border working arrangement.

How it works
Understand
We review the move, working arrangement, jurisdictions and the client’s priorities.
Assess
We identify key considerations, information requirements and areas requiring local advice.
Coordinate
We connect the relevant specialists, documentation and mobility stakeholders.
Support
We provide practical guidance and ongoing visibility as circumstances develop.
Tax is rarely an isolated part of international mobility. EMS connects tax support with the wider employee journey, helping companies and individuals manage dependencies across immigration, social security, payroll and relocation. The result is a clearer process, fewer disconnected conversations and guidance shaped around the realities of each move.
