International HR and mobility professionals meeting to discuss global mobility tax coordination

Global Mobility Tax & Immigration Support

International employee mobility involves far more than obtaining visas and work permits. Every cross-border move has tax implications that can affect employers, employees and the overall success of an international assignment.

At Hudson McKenzie, we recognise that immigration and tax are intrinsically linked. While we are a leading global immigration firm, we do not provide tax advice or tax compliance services directly. Instead, we work with a trusted network of highly experienced tax professionals and specialist tax advisers across jurisdictions worldwide to deliver seamless, coordinated solutions for our clients.

Our integrated approach ensures that immigration, tax and employment considerations are addressed together rather than in isolation, helping businesses manage international assignments efficiently while reducing compliance risks.

A Joined-Up Global Mobility Approach

Many organisations treat immigration and tax as separate workstreams. In reality, immigration decisions frequently trigger tax, payroll and social security obligations. By coordinating closely with our international tax partners, we help clients identify potential issues early in the assignment lifecycle, enabling informed planning and reducing unexpected costs.

Our collaborative approach supports:

  • International assignments
  • Business travel compliance
  • Global workforce mobility programmes
  • Cross-border employment
  • Remote and hybrid international working
  • Permanent transfers
  • Short-term assignments
  • Long-term expatriate assignments
  • Senior executive relocations
  • Global talent mobility strategies

Working with Leading International Tax Specialists

Hudson McKenzie has established relationships with independent tax professionals and specialist tax advisory firms in key business locations around the world. Where tax advice is required, we coordinate directly with the appropriate advisers, providing clients with a seamless experience while ensuring that immigration and tax advice remain aligned throughout the assignment.

Depending on the jurisdiction and assignment, our tax partners can advise on matters including:

  • Expatriate tax planning
  • Individual income tax obligations
  • Employer tax responsibilities
  • Shadow payroll
  • Tax equalisation and tax protection policies
  • Social security and totalisation agreements
  • Double taxation considerations
  • Cross-border payroll coordination
  • Employer reporting obligations
  • International assignment tax planning

Tax advice is provided independently by qualified tax professionals in the relevant jurisdiction. Hudson McKenzie does not provide tax, accounting or financial advice.

Why Immigration and Tax must be considered together

Successful international mobility requires collaboration across multiple disciplines. Immigration permissions, employment arrangements and tax obligations often develop simultaneously, and decisions made in one area can significantly impact another. Our role is to ensure that immigration strategy is coordinated with specialist tax advice, allowing clients to benefit from an efficient, compliant and commercially practical solution. This joined-up approach helps businesses:

  • Reduce compliance risks
  • Improve employee experience
  • Support HR and Global Mobility teams
  • Coordinate international assignments efficiently
  • Minimise delays and duplication
  • Access trusted advisers through a single point of contact

We work with multinational corporations, fast-growing businesses, HR professionals, Global Mobility teams and in-house legal departments managing international employees across multiple jurisdictions. Whether you are relocating a single executive or managing a large-scale global mobility programme, Hudson McKenzie can coordinate the immigration process while introducing trusted tax specialists wherever specialist tax advice is required.
