Oman levies a 15 % corporate income tax on all entities operating in the Sultanate, with a reduced 3 % rate for SMEs with taxable income below OMR 100,000. Free zone entities in Sohar, Duqm, Salalah, and Mazunah can receive tax holidays of up to 30 years. Oman also charges 5 % VAT. There is no personal income tax. Last updated: May 2026.

How does Oman’s 15 % CIT work?
Oman’s income tax is governed by the Income Tax Law (Royal Decree 28/2009), as amended. The 15 % rate applies to net taxable income — gross income from all sources minus allowable deductions — for all entities established or operating in Oman, regardless of ownership nationality.
Unlike Saudi Arabia, Oman does not differentiate between foreign and national ownership for tax purposes. Both Omani-owned and foreign-owned companies pay the same 15 % rate. This unified approach simplifies the tax regime but means there is no Zakat alternative for GCC nationals.
Filing is due within four months of the fiscal year-end with the Oman Tax Authority (OTA). Late filing penalties are OMR 100 per month of delay. Late payment penalties are 1 % per month on outstanding tax.
What is the 3 % SME rate?
Oman offers a reduced 3 % corporate tax rate for qualifying SMEs with taxable income at or below OMR 100,000 (approximately USD 260,000). This is the most generous SME relief in the GCC — the UAE’s Small Business Relief treats income as zero (but is temporary and ends in 2026), while Oman’s 3 % rate is permanent with no published sunset date.
To qualify, the SME must be registered with the Public Authority for SME Development (Riyada) and meet the authority’s criteria for workforce, revenue, and capital thresholds.
How do Oman’s free zone tax holidays work?
Oman operates four major free zones, each offering tax holidays of up to 30 years as an investment incentive:
| Free zone | Location | Key sectors | Tax holiday |
|---|---|---|---|
| Sohar Free Zone | North coast (Batinah region) | Petrochemicals, metals, logistics, manufacturing | Up to 25 years |
| Duqm SEZ | Central coast (Al Wusta) | Green hydrogen, refining, heavy industry, fisheries | Up to 30 years |
| Salalah Free Zone | South coast (Dhofar) | Logistics, manufacturing, warehousing | Up to 25 years |
| Mazunah Free Zone | South-west border (near Yemen) | Transit trade, re-export to Yemen and East Africa | Up to 25 years |
Free zone tax holidays are negotiated individually with the zone operator and the OTA. Typical conditions include minimum investment thresholds, employment targets, and sector alignment. After the holiday expires, the standard 15 % rate applies.
Duqm SEZ is the largest and most strategically significant, covering over 2,000 square kilometres and positioned as Oman’s flagship industrial zone for heavy industry and green hydrogen production. The 30-year tax holiday is the longest in the GCC.
What about Oman VAT?
Oman implemented 5 % VAT on 16 April 2021, following the GCC Unified VAT Agreement. VAT registration is mandatory for businesses with taxable supplies exceeding OMR 38,500 (approximately USD 100,000) in any 12-month period. Voluntary registration is available above OMR 19,250.
Food, healthcare, and education are zero-rated. Financial services and residential real estate are exempt. The VAT structure mirrors the UAE’s 5 % framework but with higher registration thresholds.
What unique advantages does Oman offer?
Two features distinguish Oman from other GCC tax jurisdictions:
US-Oman Free Trade Agreement — Oman is the only GCC country with a bilateral free trade agreement with the United States. American companies benefit from preferential terms on goods trade, services access, and investment protections unavailable elsewhere in the GCC. This makes Oman the default GCC entry point for US manufacturers and exporters.
Omanisation requirements — Oman mandates minimum percentages of Omani nationals in the workforce, varying by sector (10 % to 90 %). While this creates a compliance cost, it also generates government goodwill and access to Omani government contracts that foreign-dominated workforces cannot access.
Frequently asked questions
How does Oman compare to the UAE on tax?
Oman’s standard rate (15 %) is higher than the UAE’s (9 %), but Oman’s free zone holidays (up to 30 years at 0 %) are more generous than the UAE’s conditional QFZP regime. Oman’s 3 % SME rate is permanent; the UAE’s SBR (0 %) ends in December 2026. For businesses qualifying for Omani free zone holidays, the effective long-term rate can be lower than the UAE.
Does Oman tax dividends?
No. Oman does not levy withholding tax on dividends paid to shareholders, whether resident or non-resident.
Is Oman considering a DMTT?
Oman has not published DMTT legislation as of May 2026. The OECD Pillar Two framework is under review but no implementation timeline has been announced.
