Oil & Gas Contractors
in Saudi Arabia

Oil & Gas Is Still Saudi Arabia's Largest Expat Employer

From Aramco's own operations to the dense web of contractors and service companies around it, oil and gas remains the single largest source of American expat employment in the Kingdom, alongside the newer wave of Vision 2030 infrastructure and giga-project work. Rotational schedules, project-based contracts, and offshore/remote-site postings create tax planning questions that a standard office-job guide doesn't fully answer.

Rotational Schedules and the Physical Presence Test

Many oil and gas roles run on a rotation, common patterns include 28 days on/28 off, or longer project-based blocks with periodic home leave. The Physical Presence Test only cares about days outside the US, not which country you're in, so time spent on rotation in a third country (or even traveling) still counts toward the 330-day threshold.

The Bona Fide Residence Test is harder to satisfy on a rotational schedule, since it requires an uninterrupted full tax year of genuine residency. Most rotational workers rely on the Physical Presence Test instead, which makes day-tracking discipline especially important for this group.

Worked Example: A Rotational Contractor's Year

Scenario: An independent contractor earns $180,000 on a Saudi oil and gas project, working a 28-on/28-off rotation with home leave split between the US and a third country.

FAQ: Oil & Gas Contractors in Saudi Arabia

Q: Do rotation days off-site (but not in the US) still count toward the Physical Presence Test? A: Yes. The test only counts days inside vs. outside the US. Time on rotation, on leave in a third country, or even traveling all counts as time outside the US.

Q: Can I avoid self-employment tax by using an S-Corp? A: Some self-employed contractors reduce exposure by electing S-Corp status and taking a reasonable salary plus distributions, since distributions aren't subject to self-employment tax. This requires careful compensation analysis and should be reviewed with a specialist.

Q: My project is offshore in Saudi waters, does that change anything? A: Generally no for US tax purposes, physical presence outside the US is what matters for FEIE, regardless of whether you're onshore or offshore within Saudi jurisdiction.

Q: Does hazard pay or field bonuses get special tax treatment? A: No. Hazard pay and field bonuses are earned income like base salary, eligible for the FEIE up to the cap, and taxed normally above it.

Q: What if my rotation includes time in international waters? A: Time outside the United States, including in international waters or on a vessel, generally counts toward the Physical Presence Test's 330-day threshold. Keep detailed logs since this is exactly the kind of edge case that benefits from clear documentation.

Q: Does per diem count as taxable income? A: It depends on the structure. A true reimbursement of documented business expenses generally isn't taxable; a flat per diem allowance with no expense substantiation is usually treated as taxable compensation. Review your specific contract terms with a specialist.
