The US is one of the only countries to require its citizens and permanent residents (i.e., green card holders) to file annual tax returns and report their worldwide income, regardless of their actual work location. When working outside the United States, it is often the case that US persons are subject to taxation in the county where they are physically located.

The modern workforce is a mobile one and has expanded beyond the traditional short- or long-term assignment. Today, mobility includes a variety of work arrangements such as remote and hybrid work, as well as short-term business travel. This shift has provided greater flexibility in how and where employees work, allowing organizations to access a wider talent pool and operate more efficiently across different locations. However, with increased flexibility comes the challenge of navigating complex reporting and filing requirements to avoid financial, legal, and reputational risks.

The global mobility landscape is continuously evolving, often bringing significant changes that directly impact businesses, mobile employees, and the broader mobility industry.

All US citizens and permanent residents must file federal income tax returns if they meet the Internal Revenue Service (IRS) filing threshold. The size of this threshold will vary depending on factors such as age, filing status, and type of income (e.g., income from employment or self-employment). For example, a single individual under the age of 65 would be required to file a 2024 US federal income tax return if their gross income exceeded $14,600. If the earnings came from self-employment, this same person would need to file a US federal tax return if their net earnings exceeded $400.
