Global Mobility Housing: What HR and Mobile Employees Need to Know

Housing is one of the most personal and financially consequential decisions an employee faces when accepting an international assignment or permanent relocation. Should they sell their home? Rent it out? What support should the company provide? Where does the company's responsibility end and the employee's begin? These questions sit at the intersection of personal finance, tax compliance, and mobility program design. Getting the answers right matters for both the organization and the individual and their family.

Our expatriate tax partners at Global Tax Network (GTN) recently published a comprehensive look at housing considerations in global mobility programs, and it's worth taking a close read. Here are the key takeaways, along with some additional context from our perspective.

Why the Hands-Off Default Is Working

Most companies today take a hands-off approach to home-country housing, and current market conditions have reinforced that methodology. Employees that are currently sitting on low fixed-rate mortgages have little incentive to sell, and companies aren't pushing them. The support conversation has shifted almost entirely to destination housing and property management for those who retain their home during the assignment.

That said, a hands-off approach only works when it's backed by clear communication. Employees need to understand their responsibilities before they make decisions, not after a tax bill arrives.

The Tax Dimension Is More Complex Than It Looks

One of GTN's most important points is that housing decisions don't exist in a tax vacuum. An employee who retains their home-country residence while receiving company-provided housing abroad may qualify for tax relief in some jurisdictions, since they're incurring costs in two locations simultaneously. That potential benefit needs to be identified early through a tax cost projection, before the assignment is underway.

Similarly, employees who rent out their home during an assignment need to understand that rental income (net of expenses) is treated as personal income and is typically addressed in the tax equalization settlement. Renting also introduces complexity if and when the employee eventually sells, particularly regarding the U.S. federal home sale exclusion, which requires meeting a "2 out of 5 year" ownership and use test. A foreign assignment can erode that window in ways that aren't always obvious until the damage is done.

For U.S. expats in company-sponsored housing arrangements, there's also a separate tax benefit worth understanding: the Foreign Housing Exclusion under IRC Section 911, which allows qualifying employees to exclude certain housing costs from U.S. taxable income beyond what the Foreign Earned Income Exclusion already covers. The standard cap rose from $39,000 in 2025 to $39,870 in 2026, but high-cost cities like Hong Kong, Geneva, Singapore, and London carry location-specific IRS limits that can run significantly higher. This is the kind of nuance that's easy to miss without a qualified tax advisor in the loop early. 

Setting a Housing Budget That's Fair and Defensible

On the destination side, the quality of a company's housing support can make or break an assignment experience. Our partners at AIRINC, one of the primary data resources we use to develop housing budgets, take a multi-dimensional approach to determining what an appropriate housing allowance looks like in a given location. Rather than defaulting to a simple bedroom count, they factor in the type of expatriate residential areas available, property types (apartments, houses, townhouses), rental cost ranges, and quality standards across a spectrum of job levels and family sizes. The goal is a housing budget that is globally consistent, fair across the assignee population, and defensible when exceptions are requested.

That last point matters more than it might seem. Housing exceptions are among the most common and most costly in any mobility program. A well-researched budget reduces them.

When Flexibility Changes the Equation

One of the more significant shifts emerging in mobility program design is the move toward flexible, choice-based programs, where the company establishes a budget and employees direct those resources toward their own highest priorities. The housing implications are real: in a flexible program, an employee might choose to apply their mobility budget toward the cost of selling their home rather than toward benefits they don't value.

In that framing, home sale assistance becomes one of many options a mobile employee might elect. That shift has genuine implications for how companies think about program design, cost predictability, and the employee experience.

Beyond Traditional Assignments

GTN also flags an important and often overlooked category: employees moving under less traditional arrangements such as short-term assignments, permanent one-way transfers, remote work situations, or informal off-program moves. These scenarios introduce housing and tax considerations that standard long-term assignment policies weren't designed to address, including dual residency exposure and compliance gaps for cross-border work. If your mobility policy hasn't been reviewed with these arrangements in mind, it's worth revisiting.

The Bottom Line

Housing decisions are high-stakes, emotional, and frequently misunderstood by the employees who need to make them. The organizations that handle this well share a common trait: they address the hard questions early, communicate clearly about where company support ends and employee responsibility begins, and partner with knowledgeable advisors across tax, data, and destination services to fill the gaps.
