Written by Pat Jurgens | Aug 21, 2026 @ 10:27 AM

What is global mobility tax? How does tax work for international assignments? And what do mobility teams need to know about tax equalization, payroll, business travelers, remote workers and mobile compensation?

This autumn, join us with Andersen as we present Global Mobility Tax: The Essentials Refresher, a three-part webinar series designed to make global mobility tax a little easier to navigate.

Whether you work in Global Mobility, HR or Global Tax, the series will take you from the fundamentals of mobility tax through to mobile compensation and the tax considerations associated with different types of international mobility.

Newer to mobility tax? This is a great place to build your knowledge. Been working with it for years? Consider this your opportunity to refresh the essentials and perhaps pick up a few new insights along the way.

What is global mobility tax?

Global mobility tax covers the employer and employee tax considerations that arise when people work across borders.

Simple enough, right?

Well, add in international assignments, allowances, equity, payroll, business travel, remote work and different tax jurisdictions, and things can quickly get more complicated.

For mobility teams, understanding the fundamentals can help you anticipate costs, identify potential issues, ask better questions and know when specialist tax expertise is needed.

That is exactly what we will explore throughout this series.

Meet the global mobility tax experts

Across the series, you will hear from me, Pat Jurgens, Director, Global Tax Research and Consulting, and my colleague Jeremy Piccoli, Director, Global Tax Solutions, alongside Andersen’s Adam Schwartz, Director and Global Mobility Tax Transformation and Technology Lead, and Lynda Ngo, Director, Global Mobility.

Together, we will bring deep global mobility tax expertise and different perspectives to the issues mobility teams encounter every day, from gross-ups and mobility payroll to international assignment compensation, tax equalization, business travelers and remote workers.

Our aim is simple: take topics that can quickly become complex and make them practical, understandable and relevant to the decisions mobility professionals need to make.

So, bring your questions. We will bring the tax knowledge.

Session 1: What is Mobility Tax?

September 22 | 10:00 AM Boston / 4:00 PM Brussels

We are starting with the fundamentals.

What exactly do we mean by mobility tax? How are common mobility allowances and expenses taxed? What is a gross-up? And where does payroll fit into the picture?

In this first session, we will cover:

  • The basics of mobility tax
  • Taxation of typical mobility scenarios, allowances, and expenses
  • Introduction to gross-ups
  • Introduction to mobility payroll

If you are newer to mobility tax, this is the perfect place to start. If you have been around it for years, think of it as a chance to make sure those foundations are still firmly in place.

Session 2: Tax and Mobile Compensation

October 21 | 10:00 AM Boston / 4:00 PM Brussels

How does tax affect international assignment compensation?

Our second session moves beyond the basics to explore the relationship between global mobility tax, compensation and assignment costs.

We will discuss:

  • Taxation of Equity

  • Compensation structuring for international mobility

  • Managing International Assignment Tax Costs

  • Corporate tax considerations

  • Cost estimates and scenario planning

For mobility teams balancing employee experience, compliance and program costs, this is where things get particularly interesting.

Session 3: Tax Considerations for Different Assignment Types

November 17 | 10:00 AM Boston / 4:00 PM Brussels

An international assignee, a business traveler and a remote worker may all be working across borders, but their tax considerations can look very different.

Our final session explores how tax considerations change depending on how an employee is mobile.

We will cover:

  • An Introduction to Tax Equalization and Tax Protection

  • Taxation of Short-Term Assignees, Business Travelers and Remote Workers

  • Application of Tax Treaties

  • Social Security and Totalization Agreements

With organizations managing more varied forms of employee mobility, understanding these differences is an increasingly important part of running an effective global mobility program.
