When does your business need Global Mobility support?
Global Mobility starts when work crosses borders. That can mean one employee or a single short-term project. You do not need a dedicated department to get started, but you do need clear responsibilities.
What is Global Mobility?
Global Mobility is how a business manages work across borders. An employee might relocate for a new role, work temporarily at a client’s overseas location, or ask to work remotely from another country. Four things come together: what the business needs, what the employee expects, what it costs, and what the laws and regulations in the countries involved require.
That makes Global Mobility more than arranging a move. Tax advisors, immigration specialists, and relocation providers each bring their own expertise. Someone also needs to connect their advice, involve HR, Total Rewards / Compensation & Benefits, and payroll, and make sure the business can make timely decisions.
Four situations where it already matters
Cross-border work often starts with a practical request. In these four situations, it pays to review the implications before making commitments.
1. An employee is assigned to an overseas client
The project is scheduled and the flight is booked. But has anyone checked whether a notification or work permit is required, which employment terms apply, and which country’s social security system covers the employee? Requirements can apply even to a short project. Leaving these checks until after departure can lead to delays, unexpected costs, or noncompliance.
2. You hire someone who lives in another country
The offer is ready. Who will be the legal employer, where will the employee actually work, and where must payroll taxes and social security contributions be paid? You also need to assess whether the work could affect the company’s tax position. Address these questions before the offer is signed so you understand which arrangements are workable and what obligations and costs come with them.
3. An employee relocates for a new role
What support will you offer, who pays for what, and how does the package fit your compensation policy? Without a coordinated decision, different teams may make different commitments. That can lead to unclear expectations, inconsistent treatment, or costs that were never included in the budget.
4. Someone asks to work remotely from abroad
A laptop makes remote work possible. It does not settle the conditions under which that work can take place. The country, duration, activities, and employing entity are among the factors that determine the potential tax, social security, and employment law implications. Approving a request before reviewing them can mean overlooking obligations and costs.
Does this apply to one employee or a one-time request?
Yes, requirements can apply even then. Headcount alone does not determine whether a situation needs attention. The relevant countries, nationality, activities, and duration can all matter.
Different rules can also lead to different answers. In the EU, traveling for a meeting, for example, does not automatically constitute a posting under posted-worker rules. Social security is assessed under a different framework. The European Commission explains the distinction in its guidance on temporary work abroad.
Tax treatment also depends on the countries and circumstances. There is no single EU rule governing how all income earned while working in another country is taxed. See the official guidance on income tax abroad.
You can start with one specific question. You do not need to build a Global Mobility department or commit to an ongoing engagement. We look at the support the situation calls for.
Who takes ownership without a dedicated team?
That may be HR, Total Rewards, or the manager leading an international project. Someone needs to keep the overall picture in view: which decisions are needed, who provides each area of expertise, and who makes sure agreed actions happen?
Even when each specialist handles their part well, gaps can emerge between those parts. Who connects the tax advice with employment terms, payroll, and the commitments made to the employee? Bringing those pieces together takes clear coordination.
Start with five practical questions
- Who will work where? Establish the employee’s residence, nationality, work locations, and employing entity.
- What will they do, and for how long? Describe the actual activities and expected working pattern.
- What has already been agreed? Include compensation, allowances, support, and budget.
- Who needs to review the arrangement? Identify the internal colleagues and specialists you need.
- Who owns the process? Agree who decides, coordinates, and follows through.
These answers give you a useful starting point for a review. They do not replace the checks themselves. If you are unsure who needs to be involved or who should keep the overall picture in view, we can help you put that in place.
