For a small or mid-sized business the UAE is cheaper on tax and Oman is cheaper on government fees. For a large multinational group the tax gap closes almost entirely. Which of those two sentences applies to you is the whole question, and most comparisons never ask it.
First, the exchange-rate excuse is removed
Comparisons between Gulf jurisdictions usually hedge every figure with a note about exchange rates. There is no need. The Central Bank of Oman fixes the rial at USD 2.6008, and has done since the last change in parity in 1986. The dirham is likewise pegged to the dollar. Neither rate has moved in this century. So every conversion below is arithmetic, not a snapshot — one rial is about 9.55 dirhams — and if a figure in this article is wrong, it is wrong because a government changed a rule, not because a currency moved.
The finding that reframes the whole comparison
Both countries now operate a 15% global minimum tax on large multinational groups. Oman does it through Royal Decree 70/2024, the Supplementary Tax Law, issued 31 December 2024, published in Official Gazette 1578 on 5 January 2025 and effective for fiscal years beginning 1 January 2025. The UAE does it through its Domestic Minimum Top-up Tax, also effective for financial years starting 1 January 2025. Both use the OECD threshold of EUR 750 million in consolidated revenue in at least two of the four preceding years.
If your group is in scope, the UAE's advertised 9% becomes a 15% effective floor — the same nominal rate as Oman's standard corporate tax. The headline difference that dominates every comparison article simply disappears at the top of the market.
Below the threshold, the difference is real and it favours the UAE: 9% above AED 375,000, with the first AED 375,000 at 0%, against Oman's 15% from the first rial.
One difference in the machinery is worth noting because the two governments made opposite choices. The UAE Ministry of Finance states plainly that the Income Inclusion Rule is not applied in the UAE — it has adopted the domestic top-up tax only. Oman's law is read differently by different advisers: some describe Royal Decree 70/2024 as introducing both a domestic top-up tax and an income inclusion rule, others as an income inclusion rule alone. The gazette text speaks of topping the original tax up to the equivalent of 15% without using the OECD labels. If your group has low-taxed subsidiaries outside Oman, that ambiguity is worth resolving with the Tax Authority before you assume the Omani rule reaches them.
Corporate tax, side by side
| Measure | Oman | UAE |
|---|---|---|
| Standard rate | 15% from the first rial | 9% above AED 375,000 |
| Tax-free band | None | AED 375,000 (about OMR 39,000) |
| Small business relief | 3% rate, tight conditions | 0% up to AED 3m revenue, to 31 Dec 2026 |
| Petroleum | 55% | Emirate-level, outside the federal law |
| Withholding tax | 10% on services, royalties, management fees | 0% |
| Global minimum tax | 15% from 1 Jan 2025 (RD 70/2024) | 15% from 1 Jan 2025 (DMTT) |
| Statute | Royal Decree 28/2009, Article 112 | Federal Decree-Law 47 of 2022 |
Oman's 3% rate is narrower than it sounds
Oman's reduced rate for small enterprises is quoted constantly and qualified almost never. To get it, an establishment or limited liability company must meet all of the following: registered capital not exceeding OMR 60,000 at the start of the tax year; gross income not exceeding OMR 150,000 in the tax year; an average of no more than 25 employees; and an activity outside air and sea transport, natural resource extraction, banking, insurance and finance, and public utility concessions.
OMR 150,000 of gross income is roughly AED 1.43 million in turnover. A capital ceiling of OMR 60,000 rules out most companies that need a visa quota or a bank facility. If you are moving a real operating business to Oman, assume you are on 15%, not 3%.
The Oman Tax Authority publishes the 3% rate without publishing the thresholds. Its own rates page says only "3% according to specific conditions (such as revenues and number of employees)". The figures above come from PwC's summary of the executive regulations, not from a government page — so treat them as well-sourced secondary rather than official.
We also could not establish from the law or the Tax Authority whether foreign ownership of an Omani-registered company disqualifies it from the 3% rate. No official source we reached addresses it.
Compare that with the UAE's Small Business Relief under Ministerial Decision 73 of 2023: revenue up to AED 3 million in the tax period, and the business is treated as having no taxable income at all. That is roughly OMR 314,000 of turnover at 0%, against Oman's OMR 150,000 at 3% — about twice the ceiling at a lower rate. It is also time-limited, applying to tax periods from 1 June 2023 to 31 December 2026, and it excludes Qualifying Free Zone Persons and members of multinational groups with consolidated revenue above AED 3.15 billion. Separately, the withholding tax line deserves more attention than it usually gets. Oman withholds 10% on payments to non-residents for royalties, research and development, software use rights, management fees and services. For a foreign-owned Omani company that pays its parent a management charge or a licence fee, that is a recurring 10% leakage. The UAE rate is currently 0%. Oman has permanently suspended withholding on dividends and interest following a Royal Directive of 11 January 2023, but the services and royalties limb is very much alive.
VAT: the one line where the two are genuinely the same
| Measure | Oman | UAE |
|---|---|---|
| Rate | 5% | 5% |
| Mandatory registration | OMR 38,500 (about AED 368,000) | AED 375,000 (about OMR 39,000) |
| Voluntary registration | OMR 19,250 | AED 187,500 |
| Introduced | 16 April 2021 (Royal Decree 121/2020) | 1 January 2018 |
Omani returns are filed quarterly, with payment due 30 days after quarter-end. We could not find the UAE filing frequency stated on either u.ae or the Ministry of Finance site, and the Federal Tax Authority's own pages are blocked to automated retrieval, so we are not going to assert one. Once converted at the peg, the two registration thresholds are within about two per cent of each other, which is not a coincidence — both derive from the GCC VAT framework.
Personal income tax: the change most comparisons predate
This is the single biggest recent shift and it runs against Oman. Royal Decree 56/2025, the Personal Income Tax Law, was issued on 22 June 2025 and published in Official Gazette 1602 on 30 June 2025. It takes effect on 1 January 2028.
- The rate is a flat 5% (Article 8).
- It applies to income above OMR 42,000 a year — roughly AED 401,000.
- Article 6: a tax resident is taxed on worldwide income; a non-resident on Oman-sourced income only. Residence is presence in Oman for more than 183 days in a tax year.
- Article 25 exempts, among other things, diplomatic salaries, education and healthcare expenditure, disposal of a primary residence subject to conditions, zakat, interest on government securities, and inheritance.
- Article 33: an annual electronic return within six months of year-end. Employers may file for employees whose income is salary or pension only, on request.
The UAE's position is one sentence on the government portal: "The UAE does not levy income tax on individuals." The taxes it lists are VAT, excise and corporate tax.
It reaches income earned outside Oman. Article 6 taxes an Omani tax resident on worldwide income. If you are in Oman more than 183 days a year and you have rental income, dividends or consultancy fees abroad, they are within scope above the threshold. Most summaries describe this as a tax on Omani salaries. It is broader than that.
No executive regulations have been published yet. The rate, the threshold and the filing deadline are in the decree; the mechanics are not. Anyone giving you a definitive answer today on withholding, on foreign tax credits or on how employer filing will work is guessing.
Foreign ownership: opposite directions of travel
Both countries allow 100% foreign ownership. They arrived there differently and they are moving differently, and that matters more than the headline.
Oman opened up under the Foreign Capital Investment Law, Royal Decree 50/2019, which removed the requirement for an Omani shareholder. It then published a negative list of prohibited activities in Ministerial Decision 209/2020, issued 8 December 2020 and in force from 14 December 2020. That list was extended by Ministerial Decision 435/2024, dated 29 August 2024 and published in Official Gazette 1560 on 1 September 2024, which added 28 activities — handicrafts in leather, palm leaf, wood, silver, copper and aluminium; frankincense water and oil; traditional cosmetics and perfumes; pottery and ceramics; incense; personal care services; equipment rental; certain retail; aquaculture; and fuel station operation. UNCTAD records the resulting total at 123 prohibited activities.
The UAE went the other way. Federal Decree-Law 26 of 2020, amending the Commercial Companies Law, "annuls the requirement for commercial companies to have a major Emirati shareholder or agent", opening more than 1,000 commercial and industrial activities to full foreign ownership. The Commercial Companies Law was subsequently reissued as Federal Decree-Law 32 of 2021. In fairness to Oman, its restriction is at least enumerated in a published legal instrument you can read: the UAE portal says the exclusion relates to "seven sectors" and a Cabinet committee decides which activities qualify, but it does not name the seven sectors. Oman's regime is more restrictive; the UAE's is less transparent about where its limits actually fall.
Oman prohibits 123 named activities and was still adding to the list in August 2024. The UAE removed its blanket restriction in 2020–21 and restricts only a narrow category of "economic activities with a strategic impact".
If your activity sits anywhere near crafts, personal services, small-scale retail or equipment hire, check the Omani list before anything else. Our guide to restricted activities goes through it.
Minimum capital
- Oman, public joint stock company (SAOG): OMR 2,000,000, or OMR 1,000,000 where formed by conversion from another legal form — Royal Decree 18/2019, Article 91.
- Oman, closed joint stock company (SAOC): OMR 500,000 — same article.
- Oman, limited liability company: no minimum stated in the law. A one-person company is permitted under Articles 3 and 4(7), also with no stated minimum.
- UAE: no minimum capital figure appears on the official mainland company pages we could reach. Free zones set their own nominal figures.
A widely repeated claim gives a minimum share capital of OMR 150,000 for foreign-owned Omani companies. We could not trace it to any instrument. It is not in the Commercial Companies Law, and law firms writing in 2021 were still describing the foreign-investor minimum as unresolved pending executive regulations. Treat any specific minimum-capital figure for a foreign-owned Omani LLC as unverified until someone shows you the article.
Setup and renewal costs, and why a clean comparison is impossible
Oman charges small itemised statutory fees per transaction. UAE free zones sell a bundle. Setting OMR 48 against AED 35,000 is arithmetically correct and analytically useless, because the Omani figure excludes the office lease, the activity approvals, the municipality licence and the professional fees that the free zone package includes.
| Oman — official fee | OMR | About AED |
|---|---|---|
| New commercial register, registration | 40.200 | 384 |
| New commercial register, administrative fee | 8.100 | 77 |
| Chamber of Commerce new membership certificate | 33 | 315 |
| Work permit, category one profession | 300 | 2,865 |
| Work permit, category three profession | 200 | 1,910 |
| Job Security Fund fee | 10 | 96 |
| Work visa (Royal Oman Police) | 20 | 191 |
| Investor visa, ten years | 500 | 4,776 |
Against that, the published charges of one UAE free zone. DMCC is used here because it publishes a real schedule rather than a brochure figure; it is not the cheapest zone and it is not representative of all of them.
| DMCC — published charge | AED | About OMR |
|---|---|---|
| Application fee, one-time | 1,035 | 108 |
| Registration fee, one-time | 9,020 | 944 |
| Annual licence fee | 20,285 | 2,124 |
| Establishment card, annual | 1,825 | 191 |
| First-year package, DMCC's own range | 35,000–50,000 | 3,665–5,235 |
The Omani figures are government fees only. They exclude the commercial lease that a commercial registration requires, municipality licensing, activity-specific approvals from sector regulators, and any agent's charge.
The DMCC figures include workspace — a flexi-desk or co-working allocation is inside the package price. That is a large part of why the numbers look so far apart.
Oman publishes no consolidated fee schedule. Fees appear one service at a time on gov.om, and Chamber of Commerce renewal fees are only displayed inside the transaction itself. The UAE has the mirror-image gap: free zones publish, but we found no official consolidated schedule for mainland Dubai trade licences — every figure in circulation comes from a consultancy.
One genuinely comparable line does exist: what the government charges to put one expatriate on your payroll. In Oman that is OMR 230 to 330 — a work permit at OMR 200 to 300 by profession category, the OMR 10 Job Security Fund fee and the OMR 20 work visa — or about AED 2,200 to 3,150. In the UAE the MoHRE work permit costs AED 50 to apply plus AED 250, AED 1,200 or AED 3,450 to issue depending on the company's classification. A well-classified UAE employer pays roughly AED 300 where an Omani employer pays ten times that. A poorly classified one pays more than Oman's top tier.
Localisation: published percentages against published silence
The UAE publishes its quota, its threshold and its penalty, and escalates the penalty on a schedule announced in advance.
| Oman | UAE | |
|---|---|---|
| Quota | Set by ministerial decision per sector | 2% a year in skilled roles, 1% each half-year |
| Threshold | Article 22 duties at 25+ workers | 50+ employees; 20–49 must hire one national |
| Penalty | OMR 500–1,000 per unfilled Omani post, doubling on repeat | AED 10,000 a month per unfilled post in 2026 |
| Annualised per head | About AED 4,776–9,551, one-off | AED 120,000, about OMR 12,563 |
The UAE contribution started at AED 6,000 a month per Emirati not appointed for 2022 and MoHRE announced it would rise AED 1,000 annually until 2026, which puts 2026 at AED 10,000 a month, or AED 120,000 a year, applied from 1 July 2026 for a first-half shortfall. Be careful with the many 2026 guides quoting AED 9,000 a month, or AED 108,000: that is the 2025 rate, payable in January 2026 for the 2025 target. Both numbers are current; they penalise different periods.
Oman's position is more mixed than it is usually described, in both directions. Article 23 of Royal Decree 53/2023 delegates the percentages to the Minister of Labour and the law itself contains none. Zone-level minimums are genuinely published — Duqm at 10%, Al Mazunah at 20%, Sohar at 15% for the first ten years. What does not exist is a current, general, enforceable sector table with tariffed penalties attached, which is why our Omanisation guide is explicit that every complete sector table online is a secondary compilation. So: Oman publishes something. It does not publish enough for an employer outside a zone to self-assess.
Article 43(2) of Royal Decree 53/2023 makes it a lawful ground to terminate a non-Omani worker where the employer appoints an Omani as a replacement in the same occupation. The employer must give the ministry at least three months' notice.
There is no UAE equivalent of that provision in the Emiratisation framework, which operates through targets and financial contributions rather than by making displacement of a named foreign worker a statutory dismissal ground. If you are relocating a team to Oman, this belongs in your planning, not in a footnote.
What it costs to employ someone
Under Royal Decree 52/2023, the Social Protection Law, in force from 1 January 2024, Omani employees attract employer contributions of 11% for old age, disability and death, 1% for work injuries, 0.5% for employment security and 1% for sick leave, against employee contributions of 7.5% and 0.5%. The contribution wage ceiling is OMR 3,000 a month. For non-Omani workers the coverage is much narrower: the work injuries branch applies per Board decision, and the sick leave branch applies compulsorily, both phased in after the law's issuance. Note that PwC's summary sets out the Omani rates differently — employer 14.5% and employee 8%, a combined 22.5% — which does not reconcile line by line with the branch percentages in the decree. The difference is presumably aggregation and phase-in, but the two sources say different things and we are not going to average them.
In the UAE there are no social insurance contributions for expatriate employees at all. For UAE nationals in the private sector, Federal Decree-Law 57 of 2023 sets a total of 26% of pensionable salary for new entrants from 31 October 2023 — employee 11%, employer 15% — with the government paying 2.5% on the employer's behalf where pensionable salary is below AED 20,000 a month. On end of service, Article 61 of Royal Decree 53/2023 entitles a worker to gratuity of not less than the basic wage for each year of service, pro-rated for part years. The UAE operates a statutory gratuity alongside a voluntary alternative savings scheme under Cabinet Resolution 96 of 2023, in effect from 1 November 2023, under which employers pay a monthly subscription into an investment fund vetted by the securities regulator. The contribution percentages are not published on MoHRE's own pages.
Several advisers report that Oman will replace expatriate gratuity with a mandatory savings scheme from July 2027, funded by an employer contribution of 9% of basic wage with a guaranteed minimum return of 2%.
We could not locate a primary instrument for any of that — not the 9%, not the 2%, not the date. If it lands as described it converts a back-loaded liability into a monthly cash cost and is materially worse for employers than the UAE's voluntary scheme. Plan for it as a risk; do not budget it as a fact.
Where Oman genuinely looks worse
A comparison that only lists advantages is not a comparison. On the evidence above, these are the lines where a business is better off in the UAE:
- No tax-free band. Oman charges 15% from the first rial; the UAE charges nothing on the first AED 375,000.
- Small business relief. UAE 0% up to AED 3m of revenue against Oman 3% up to OMR 150,000 of gross income, with a capital ceiling and a 25-employee cap on top.
- Withholding tax. 10% on cross-border services, royalties and management fees, against 0%.
- Personal income tax from 2028, on worldwide income for residents, against none.
- A negative list that is still growing, against a regime that liberalised and has not visibly re-closed.
- Per-head government labour cost — around AED 2,200 to 3,150 in Oman against AED 300 for a well-classified UAE employer.
- Article 43(2), which makes replacement by an Omani a lawful ground to dismiss a foreign worker.
- No consolidated fee schedule and no general Omanisation table, so an employer cannot self-assess two of its largest recurring costs.
The lines that run the other way are worth stating too, and they are not nothing: no monthly localisation penalty, a materially lower cost to register a company, a 3% municipality levy on residential rent in Muscat against 5% in Dubai and Abu Dhabi, and above EUR 750 million of group revenue a tax position that is now effectively identical.
Where the sources disagree
- Oman's Pillar Two mechanism. Some advisers read Royal Decree 70/2024 as introducing both a domestic top-up tax and an income inclusion rule; others as an income inclusion rule only. The UAE's position is unambiguous by contrast: domestic top-up tax only, no income inclusion rule.
- The 2026 Emiratisation fine. AED 10,000 a month for the 2026 shortfall, or AED 9,000 a month for the 2025 shortfall billed in 2026. Both figures are live and they measure different things.
- Omani social insurance rates. The branch percentages in Royal Decree 52/2023 do not reconcile with PwC's combined 22.5%.
- Omani expatriate end of service. The 9% provident contribution and the July 2027 date are reported consistently by advisers and appear in no primary instrument we could reach.
Is corporate tax lower in the UAE than in Oman?
Can I get Oman's 3% small business tax rate?
Will I pay income tax if I move to Oman?
Is it cheaper to set up a company in Oman or Dubai?
Is Omanisation stricter than Emiratisation?
Can a foreign investor own 100% of a company in Oman?
If you are choosing between the two, the honest framing is this: the UAE is the cheaper tax jurisdiction below the multinational threshold and the more transparent one on setup costs, while Oman is cheaper on government fees, on localisation penalties and on the levy attached to where you live. Our office can price the Omani side of that properly — the fees above are real, but they are the floor, and the lease and approvals are where the actual number is decided.
