(OMAN) — Oman will introduce a Personal Income Tax on January 1, 2028, becoming the first Gulf state to impose a broad tax on individual income under a law framed as both revenue reform and fiscal signalling.
The change comes under Royal Decree No. 56/2025, issued and published on June 30, 2025. Omani officials have tied the measure to Vision 2040, a long-running plan to reduce reliance on hydrocarbons, widen non-oil revenue, and present a steadier fiscal profile to lenders and investors. Oil has historically supplied most public revenue, leaving the budget exposed to swings in global prices.
The law does not affect tax year 2026, which is filed in 2027. There is no Omani personal income tax return due for 2026 under this decree. The first taxable year is 2028, and the first returns are due within six months after that year ends, which points to a filing deadline of June 30, 2029, unless executive regulations set a different administrative rule.
Oman has set a flat 5% rate on taxable income exceeding OMR 42,000 a year, roughly $109,000 at current exchange levels. Income below that threshold is exempt. Taxable income is calculated after the threshold, exemptions, deductions, and losses. Officials have said the tax is aimed at roughly the top 1% of earners.
The law applies to Omani nationals and expatriates, with scope turning on tax residence and source rules. Tax residents are expected to be taxed on worldwide income. Non-residents face tax on specified Oman-source income. That distinction matters for expatriate professionals, senior executives, and business owners with income streams inside and outside the country.
Oman’s message is not subtle. The Ministry of Economy has said the tax is part of a push to diversify revenue and strengthen financial stability. The government wants non-oil revenue to reach 15% of GDP by 2030 and 18% by 2040. Current annual non-oil collections already include about OMR 630 million from corporate tax and OMR 645 million from VAT and excise taxes.
| Item | Before January 1, 2028 | From January 1, 2028 |
|---|---|---|
| Personal income tax | No broad Omani PIT on individual earnings | 5% on taxable income above OMR 42,000 |
| Income below threshold | Not subject to PIT | Still exempt below OMR 42,000 |
| Who is affected | No general PIT exposure | High earners, including nationals and expatriates |
| Return filing | No annual PIT return | Electronic return due within 6 months of year-end |
| Payment timing | Not applicable | Tax due at filing |
Several exemptions and deductions narrow the taxable base. The law exempts foreign-earned income for Omani tax residents, once, for up to two years. It also exempts capital gains on a primary residence if it was held for at least two years. A gain on a secondary residence is exempt once in a lifetime. Inheritance, gifts, and income from industrial property rights receive a five-year exemption after registration. Diplomatic salaries are also exempt.
Allowable deductions include education and healthcare costs for the taxpayer and family, donations to approved entities up to 5% of gross income, Zakat, waqf contributions, and interest on a loan used to buy or build a main residence, available once. Executive regulations due in 2026 are expected to define the records taxpayers must keep and how each deduction is claimed.
A simple example shows the mechanics. A tax resident with OMR 50,000 in gross annual income and no deductions would have OMR 8,000 above the exempt threshold. At a 5% rate, the tax would be OMR 400. If the same person had OMR 3,000 in allowed deductions, taxable income above the threshold would fall to OMR 5,000, reducing the tax to OMR 250.
A higher-income case is more revealing. An expatriate executive earning OMR 80,000 with OMR 6,000 of deductible education, healthcare, and approved donations would start with OMR 38,000 above the threshold. After deductions, the taxable amount would be OMR 32,000. The tax due would be OMR 1,600. The law’s burden remains modest by global standards, but it marks a clear break in GCC tax policy.
📅 Deadline Alert: The first Omani PIT year is 2028. Returns are due within 6 months after year-end, which points to June 30, 2029 for first filings.
Compliance will be digital from the start. Individuals with gross income above OMR 42,000 must file an electronic return and pay the tax when filing. Officials have said a centralized platform will connect with other government departments for verification and compliance. That should help administration, although enforcement may still be tested by limited public visibility into privately held income and offshore earnings.
Transition rules matter because the law is not fully self-executing. The decree sets the framework, but executive regulations expected in 2026 should clarify residency tests, documentation, withholding, loss treatment, and audit procedures. Existing grandfather-type relief already appears in the text through the two-year foreign-income exemption, the residence gain rules, and the five-year industrial property relief. Taxpayers considering restructurings or asset sales in 2026 and 2027 will want those regulations before locking in a plan.
U.S. citizens and green card holders in Oman should treat this as a second-layer compliance issue, not a substitute for U.S. filing. The United States taxes citizens and resident aliens on worldwide income. IRS [Publication 54](https://www.irs.gov/pub/irs-pdf/p54.pdf), [Publication 519](https://www.irs.gov/pub/irs-pdf/p519.pdf), and [Publication 901](https://www.irs.gov/pub/irs-pdf/p901.pdf) remain the starting points for residence, treaty, and foreign income rules. Omani tax paid from 2028 may support a foreign tax credit on a U.S. return, subject to the normal limits and sourcing rules.
⚠️ Warning: U.S. taxpayers in Oman may still need FBAR and Form 8938 filings if foreign account thresholds are met. The new Omani tax does not replace those rules.
| Question | Answer under the new law |
|---|---|
| Who is most affected? | High earners above OMR 42,000, including expatriates |
| Rate structure | Flat 5% rate above the threshold |
| First taxable year | 2028 |
| First expected filing deadline | June 30, 2029 |
| Tax base | Gross income less threshold, deductions, exemptions, and losses |
The practical next steps are straightforward. High earners in Oman should map expected 2028 income now, review whether residence or source rules will apply, and keep records for deductible education, healthcare, donations, and housing loan interest. Employers should prepare payroll and compensation reporting systems before the executive regulations arrive. U.S. taxpayers should also review foreign tax credit planning and annual reporting duties through the IRS international tax portal at [IRS international taxpayers](https://www.irs.gov/individuals/international-taxpayers). If a move, bonus payment, asset sale, or status change is planned before January 1, 2028, professional advice is worth obtaining before the rules harden.
