Kuwait Income Tax for US Expats: Treaty, FBAR, Filing
Author: Randall Brody, Enrolled Agent | Licensed by the U.S. Department of the Treasury | Last Reviewed: August 2026
Kuwait does not levy a personal income tax on individuals, so Americans working there pay no Kuwaiti tax on their salary. They still file a US tax return every year, report their Kuwaiti bank accounts, and in most cases claim the foreign earned income exclusion to reduce or eliminate the US tax owed. There is no US-Kuwait income tax treaty and no totalization agreement, which means no treaty benefits are available and self employed Americans in Kuwait still owe US self-employment tax.
Does Kuwait Tax Personal Income?
No. Kuwait does not levy a personal income tax on individuals, including foreign nationals employed there. Salary earned in Kuwait is not taxed locally.
Kuwait taxes corporate profits of foreign-owned companies operating in the country, and it operates a social security system for Kuwaiti nationals only. Neither reaches the employment income of an expatriate worker. Expatriates face no mandatory social security or other payroll tax deductions from their salaries.
Because Kuwait collects no income tax from you, there is no foreign tax to credit against your US liability. That single fact shapes everything else on this page. In a high-tax country, foreign tax credits usually erase the US bill. In Kuwait they cannot, which makes the foreign earned income exclusion the main relief available and makes the annual US filing genuinely consequential.
Is There a US Kuwait Tax Treaty?
No. There is no comprehensive income tax treaty in force between the United States and Kuwait.
Without a treaty, Americans in Kuwait cannot claim treaty benefits, cannot use a residency tie-breaker to settle competing claims on their income, and cannot obtain reduced withholding rates on US source income.
For most Americans working in Kuwait on an employment contract, this is less damaging than it sounds, because Kuwait is not taxing the same income, so there is no double taxation to relieve. The gap matters most for US source investment income and for anyone whose residency position is genuinely contested.
US Kuwait Totalization Agreement and Social Security
No. There is no totalization agreement between the United States and Kuwait.
A totalization agreement determines which country’s social security system a worker pays into, preventing contributions to both. Without one, no such coordination applies.
An American employed by a Kuwaiti company is generally outside the US Social Security system for those wages, earning no US credits for those years.
An American who is self-employed in Kuwait remains liable for US self-employment tax on net earnings, and the foreign earned income exclusion does not reduce it. It is entirely possible to owe no US income tax on Kuwaiti earnings and still owe self-employment tax on the same money.
What US Taxes You Still Owe While Living in Kuwait
US citizens and green card holders must file a US return on worldwide income no matter where they live, and no matter whether the country they live in taxes them.
The foreign earned income exclusion allows up to $132,900 of foreign earned income (2026 amount) to be excluded from US tax if you satisfy either the physical presence test or the bona fide residence test. A foreign housing exclusion can cover qualifying housing costs above a base amount (16% of the FEIE, or $21,264 for 2026). The standard housing expense limit is 30% of the FEIE ($39,870), but Kuwait has higher location-specific limits: $64,400 for Kuwait City and $57,700 for all other cities in Kuwait.
Americans abroad get an automatic extension to June 15 to file, with further extension available on request. The extension covers filing only. Tax remains due on the original April deadline and interest runs from there.
With no Kuwaiti income tax paid, there is no foreign tax credit to claim. Income above the exclusion is taxed by the United States with nothing to offset it.
Reporting Kuwaiti Bank Accounts
If the combined highest balance across your foreign financial accounts crosses $10,000 at any point in the year, you must file a Foreign Bank Account Report (FBAR / FinCEN Form 114). The test looks at the aggregate of all accounts and at the highest balance reached, not the year-end closing balance.
This report is filed separately from your tax return, with FinCEN (not the IRS), on its own deadline (April 15, with an automatic extension to October 15). The penalties for missing it are severe.
A second requirement (Form 8938 under FATCA) covers specified foreign financial assets more broadly and is filed with the tax return itself. For taxpayers living abroad, the thresholds are higher:
- Single or married filing separately: more than $200,000 on the last day of the year, or more than $300,000 at any time during the year
- Married filing jointly: more than $400,000 on the last day of the year, or more than $600,000 at any time during the year
Kuwaiti bank accounts, end-of-service/indemnity balances, and investment accounts held in Kuwait can all count toward these thresholds.
