Oman expat tax guide
Middle East · how a foreigner who moves to Oman is taxed · 2026 · Very expat-friendly
If you move to Oman, you become a tax resident when more than 183 days in a tax year (applies under the PIT law from 2028). As a resident you are taxed on a territorial basis — Currently no personal income tax, so a new resident's income is untaxed; but from 1 Jan 2028 tax residents (nationals and expats) will be taxed on worldwide income above the threshold. The top personal income tax rate is 0% (no personal income tax). A foreign pension is treated as: Not taxed currently; from 2028 income earned abroad and foreign-employment salaries are listed as exempt under the PIT law. Oman also offers the 18-month foreign-income exemption (from 2028) regime, which can sharply change this picture. It lacks a US tax treaty and lacks a US totalization agreement. Overall it reads as very expat-friendly for an inbound mover. General information, not tax advice — verify with Oman's tax authority.

What this means if you relocate to Oman
The first thing that matters is tax residency: more than 183 days in a tax year (applies under the PIT law from 2028). The 183-day line is the headline trigger, but a home, family or business ties can make you resident sooner — so counting days alone is risky.
Once resident, Oman largely leaves foreign income alone (territorial basis), which is why it appears on lists of friendly destinations for expats and remote workers. Crucially, Oman charges no personal income tax on individuals, so salaries, pensions and gains are not taxed locally.
Foreign pensions and investments
Foreign pension: Not taxed currently; from 2028 income earned abroad and foreign-employment salaries are listed as exempt under the PIT law. Foreign capital gains and dividends: Not taxed currently; from 2028 falls within a resident's worldwide income base above OMR 42k. These outcomes can be overridden by a double-tax treaty, which decides whether the source country or Oman taxes each stream — a key reason retirees should map their specific income against the relevant treaty.
The 18-month foreign-income exemption (from 2028) regime
Under Royal Decree 56/2025 (effective 1 Jan 2028), an individual moving from non-resident to resident status gets a one-off 18-month exemption on foreign income; the law also exempts income earned abroad and foreign-employment salaries.
Special regimes have eligibility tests, time limits and sunset dates that change frequently. Treat the summary above as a starting point and verify the current terms with Oman's tax authority before relying on it.
US citizens and social security in Oman
| Question | Oman |
|---|---|
| US income tax treaty? | No |
| US social-security totalization agreement? | No |
| Tax basis for residents | Territorial |
| Top personal income tax | 0% (no personal income tax) |
There is no US tax treaty with Oman, so US citizens rely on the Foreign Tax Credit (and the Foreign Earned Income Exclusion) under US domestic law to soften double taxation. With no totalization agreement, you can be exposed to social-security-type charges in both the US and Oman. See our guides on FEIE vs the Foreign Tax Credit and totalization agreements.
