What to do if You Work Outside the US and Haven’t Filed a US Tax Return

Important note on streamlined filing compliance procedures -- This article specifically discusses the streamlined foreign procedures, not the domestic procedures. To qualify for the foreign procedures, a taxpayer must meet the IRS’s non-residency requirement. For a US citizen, this means that in one of the past three years for which the original or properly extended US tax return due date has passed, they did not have a US residence and were physically present outside the US for at least 330 full days.

US citizens and permanent residents (green card holders) working outside the United States generally are still required to file annual US tax returns, and the IRS is constantly updating its technology to better locate non-filing taxpayers and bring them into compliance. However, in addition to increasing its enforcement capabilities, the IRS has also taken steps to encourage non-filers to come into compliance by waiving penalties for those taxpayers eligible to take advantage of the streamlined filing compliance procedures (streamlined procedures).

And this lack of awareness can lead to unfiled returns and substantial penalties.

Navigating US Tax Reporting for Foreign Assets

Whether you're a US citizen or green card holder living abroad—or supporting employees who are—the US tax system presents unique challenges. Unlike most countries, the United States taxes individuals based on citizenship rather than residency. As a result, US citizens and green card holders must file annual US income tax returns and report worldwide income and gains, no matter where they live or work.

What is Tax Equalization and How Does it Impact Your Mobile Employees and Your Company?

Tax equalization is a policy widely used by companies with mobile employees. At its core, tax equalization is a mechanism to ensure that an employee is neither better nor worse off financially, from a tax perspective, for having accepted an international assignment. However, there are many misconceptions about what exactly it means to be “tax equalized.” One common misconception is that implementing the policy will automatically result in high company costs and administrative burdens.
