GTN Mobility Tax Blog

As companies continue to expand globally, they are placing greater focus on optimizing their business objectives and employee development. Many are reassessing the costs, benefits, and overall impact of their relocation strategies, while looking for effective ways to move talent across borders. 

Traditional global mobility assignment structures remain essential tools for achieving these goals. The three most common global mobility assignment structures are long-term assignments, short-term assignments, and permanent (or one-way) transfers. Each provides distinct advantages depending on the organization’s priorities, timelines, and talent needs.  

Globalization has entered a new era, one where even well‑established companies may suddenly find themselves navigating unfamiliar international territory. For HR professionals, these shifts tend to move rapidly from long‑term strategy to urgent operational action.

Global mobility tax services encompass the full range of tax, payroll, and compliance activities required when employees work outside their Home country. From managing shadow payrolls to supporting tax equalization, these services help companies maintain compliance, reduce risk, and create a smoother experience for mobile employees.

Accurately budgeting and accruing for tax equalized assignment costs is essential to reduce year-end surprises and for keeping your mobility program financially predictable. The initial tax cost projection is the starting point which considers key elements of the assignment compensation package. However, the real challenge to maintain a reasonable accrual often comes with managing complexities that can arise once the assignment is underway.

When employees relocate across borders, whether internationally or within the US, they can face major tax complexities. A move from a low-tax location to a high-tax location, for example, can significantly increase their tax liability. Beyond this, they may face challenges related to the sale or rental of a home, moving expenses for state reporting purposes, residency issues, and a range of other tax considerations they may not be prepared to handle on their own.
