Leaving Money on the Table: The Tax Mistakes American Expats in Saudi Arabia Keep Making — and How to Stop

For many American professionals, a posting in Saudi Arabia feels like a financial windfall. Salaries are competitive, housing is frequently employer-provided, and — crucially — Saudi Arabia imposes no personal income tax on wages. The arithmetic seems straightforward: earn more, pay less. But the US tax code does not work that way, and the gap between what expats assume and what the IRS actually requires has cost countless Americans thousands of dollars annually.

The problem is rarely outright negligence. More often, it is a collection of well-intentioned misunderstandings, outdated advice, and incomplete planning. This article examines the most consequential errors American workers in the Kingdom make when filing their US taxes — and explains how the Foreign Earned Income Exclusion (FEIE), used correctly, can dramatically reduce a legitimate tax burden.

The Foundational Misconception: No Saudi Tax Does Not Mean No US Tax

Americans are among a small group of citizens worldwide whose government taxes them on global income regardless of where they live or work. Residency in Saudi Arabia does not suspend this obligation. The absence of a bilateral tax treaty between the United States and Saudi Arabia — a point frequently overlooked — means there is no formal mechanism to offset Saudi-side obligations against US liability, because Saudi Arabia imposes none. What exists instead is a set of US-side provisions designed to prevent double taxation in countries that do levy income taxes.

This distinction matters enormously. Expats in France or Germany can often rely on the Foreign Tax Credit to offset their US bill dollar-for-dollar against taxes already paid abroad. Expats in Saudi Arabia cannot take that route in any meaningful way, because there are no foreign taxes paid to credit. Their primary tool is the FEIE — and many of them are either not using it at all, or using it incorrectly.

What the FEIE Actually Does — and Does Not Do

The Foreign Earned Income Exclusion allows qualifying Americans abroad to exclude a set amount of foreign-earned income from US federal taxation. For the 2024 tax year, that figure stands at $126,500 per person. For a married couple where both spouses work in Saudi Arabia, the exclusion can effectively double.

To qualify, a taxpayer must meet one of two tests: the Bona Fide Residence Test, which requires establishing genuine residency in a foreign country for a full tax year, or the Physical Presence Test, which requires spending at least 330 full days outside the United States during any consecutive 12-month period.

The distinction between these two tests creates the first common error. Many expats assume their employment contract alone satisfies the bona fide residence standard. It does not. The IRS evaluates the totality of circumstances — where you maintain a home, where your family resides, where you hold social ties — and a Saudi work visa paired with frequent trips back to a house in Houston can undermine a bona fide residence claim entirely. The physical presence test, while more mechanical, requires meticulous documentation of travel dates. Missing the 330-day threshold by even a few days invalidates the exclusion for that period.

Case Study: The Housing Allowance Error

Consider a scenario that plays out with striking regularity. An American engineer accepts a role with a Riyadh-based energy company. His total compensation package includes a base salary of $180,000 and a housing allowance of $36,000 annually. He files using the FEIE, excludes $126,500 of his base salary, and pays US tax on the remainder — including the full housing allowance.

What he did not know: the Foreign Housing Exclusion, a companion provision to the FEIE, allows qualifying expats to exclude employer-provided housing allowances above a base amount from taxable income. In high-cost cities like Riyadh, the IRS sets location-specific housing cost limits that can allow exclusions well above $30,000. By failing to claim this provision, this hypothetical engineer overpays by several thousand dollars per year. Over a five-year assignment, that is a meaningful sum.

Case Study: Timing the Election Incorrectly

A second scenario involves a compliance attorney who relocates to Jeddah mid-year. She arrives in August and, eager to claim the FEIE immediately, files her return as though the exclusion applies to her entire year's income. It does not. The FEIE can only be applied to income earned during the qualifying period — the months she actually spent abroad and met the applicable test. Income earned in the United States before her departure remains fully taxable.

This seems obvious in retrospect, but the mechanics of prorating the exclusion, particularly when switching between the bona fide residence and physical presence tests or when departing or returning mid-year, generate genuine complexity. Errors in this area frequently trigger IRS notices and, in some cases, penalties.

The Self-Employment Trap

For Americans in Saudi Arabia who work as independent contractors rather than direct employees — a growing cohort as remote and consulting arrangements become more common — the FEIE carries an additional wrinkle. While the exclusion eliminates federal income tax on qualifying earnings, it does not eliminate self-employment tax, which covers Social Security and Medicare contributions. A consultant earning $120,000 through a Saudi-based engagement who successfully claims the full FEIE may still owe roughly $17,000 in self-employment tax.

This surprises many filers. The logic is counterintuitive: the income is excluded for income tax purposes but remains in scope for self-employment tax calculations. Proper planning may involve restructuring compensation arrangements, contributing to retirement accounts that reduce net self-employment income, or consulting a tax professional about whether a totalization agreement with another country might apply in specific circumstances.

What Proper Planning Actually Looks Like

Expats who manage their US tax obligations effectively in Saudi Arabia typically share several habits. They work with a CPA or enrolled agent who specializes in international taxation — not a generalist who handles the occasional expat return. They maintain meticulous records of travel dates, residency documentation, and compensation breakdowns. They file Form 2555 accurately and completely, including all required housing exclusion calculations where applicable.

They also plan proactively rather than reactively. Decisions made before departing the United States — how to handle a US-based rental property, whether to convert a traditional IRA, when to sell appreciated stock — can have lasting tax consequences that no amount of post-hoc filing strategy can fully correct.

Finally, they stay current. The FEIE exclusion ceiling adjusts annually for inflation. IRS guidance on digital income, remote work arrangements, and cryptocurrency holdings continues to evolve. What was accurate advice in 2019 may not reflect current rules.

The Cost of Inaction

The IRS does not proactively inform Americans abroad about the provisions available to them. There is no outreach program, no automatic notification that a more favorable filing strategy exists. The burden falls entirely on the taxpayer — and on the advisors they choose.

For American professionals building careers and accumulating savings in Saudi Arabia, that burden is worth taking seriously. The sums at stake are not trivial. The FEIE, the Foreign Housing Exclusion, and careful attention to the mechanics of qualifying tests represent a legitimate, legal framework for reducing US tax liability. Using that framework well is not a loophole — it is precisely what Congress intended when it enacted these provisions for Americans working abroad.

The question is not whether these tools exist. The question is whether you are using them.
