Mainland or free zone. Find your business fit.

A free zone is a customs concept before it is a tax concept. The SOHAR Freezone Rules and Regulations, published on soharportandfreezone.om and read on 14 September 2026, define the Customs Territory as any territory inside Oman excluding free zones. That single definition explains most of what follows. Your free-zone warehouse is physically in Oman and legally outside its customs territory.

So the question is not which route sounds more prestigious. It is whether being outside the customs territory helps you or gets in your way. For an exporter, a transhipper or a manufacturer feeding regional markets, it helps enormously. For a consultancy billing Omani clients, a contractor, a retailer or a trading company supplying Omani buyers, it is an obstacle you pay to keep.

• Customers inside Oman, invoiced in Oman: the mainland fits, and free-zone status adds a customs step you do not need.
• Goods in from abroad and out again to export or re-export markets: a free zone is doing genuine work.
• Manufacturing for both export and Omani buyers: model the split before choosing, because the domestic share carries duty at the point it leaves the zone.
• Services delivered remotely to foreign clients: check whether you need any premises commitment at all before paying for a zone lease.
• A physical presence near a specific port, airport or border crossing: the zone choice follows the logistics, not the incentive list.

Be honest with yourself about the mix. A plan that says ninety per cent export usually turns into a plan that says sixty per cent export within two years, because the local orders arrive and they are easy money. A mainland company can absorb that shift without renegotiating anything.

This is the most important correction on this page. A great deal of free-zone marketing was written before Royal Decree 50/2019 took effect and has simply never been updated. It offers you 100% ownership as though it were a concession available nowhere else in Oman. It is not. You can hold 100% of a mainland Omani limited liability company or one-person company, subject to the activity being open to foreign investment.

The same goes for minimum capital. There is no general statutory minimum on the mainland, and Royal Decree 38/2025, Art. 9, lets the OPAZ board exempt a zone enterprise from the requirement. Sohar publishes the same exemption at Art. 16 of its rules. Neither route asks you to lock up money to prove seriousness.

• 100% foreign ownership: available on both routes. Not a differentiator.
• No minimum share capital: available on both routes. Not a differentiator.
• Full profit and capital repatriation: published by Duqm and by OPAZ, and not restricted on the mainland either.
• Activity eligibility: still a real check on the mainland, and still a real check inside a zone, because each zone publishes its own permitted-activity list.

If a proposal you have been sent leads with 100% ownership as the reason to pay for a free zone, that proposal was not written for Oman in 2026. Ask the sender what the free zone gives you that Royal Decree 50/2019 does not, and judge the answer.

Sohar’s rules, at Art. 7, list the activities a working company may conduct inside the zone: commercial, covering import, export, general trading, storage and handling within the zone; industrial, covering manufacturing, re-assembly and remanufacturing; services, including logistics and consultancy; banking and financial; educational; and health. The operating authority also maintains a list of prohibited activities under Art. 8, which it can amend.

That structure repeats across the zones with different emphasis. Salalah Free Zone, on sfzco.com read on 14 September 2026, promotes logistics, pharmaceuticals, green hydrogen, petrochemicals and garment manufacturing. Duqm, on duqm.gov.om, leads with port and maritime operations, the Oman Drydock, tourism and heavy industry. Al Mazunah, on madayn.om, lists commercial, service and industrial sectors and positions itself around trade with Yemen and transit to East Africa.

• Ask the operator to confirm your exact activity in writing before you commit to anything.
• A famous zone name does not mean your activity is on its list, or that a suitable unit is free.
• Some activities are excluded from the tax benefit even where they are permitted to operate. Duqm names banks, financial institutions, insurance, telecoms and land transport companies.
• Check whether the activity needs a sector regulator’s approval as well as the zone licence.
• If you would need a mainland licence anyway to serve part of the market, price both before choosing.

Zones do not compete on activity lists so much as on what is physically next door. Read the list, then look at the map.

OPAZ, the Public Authority for Special Economic Zones and Free Zones, was established by Royal Decree 105/2020 and oversees all of them. Royal Decree 39/2026 issued its current statute. That common supervisor is why the zones are often written about as though they were interchangeable. They are not. The table below sets out what each authority itself published, as read on 14 September 2026.

Two honesty notes on that table. First, soharportandfreezone.com would not complete certificate verification when we tried it on 14 September 2026, so the Sohar figures come from the zone’s own Rules and Regulations document hosted on soharportandfreezone.om, not from a consultancy summary. Second, the Salalah Omanisation figure is genuinely contradictory between the zone’s own site and the OPAZ FAQ, and we would rather show you the contradiction than pick the friendlier number.

This matters more than any single zone brochure, because it changes what a new applicant should expect. The English text of the decree, read on decree.om on 14 September 2026, sets out the structure below. As with all Omani legislation in English, the Arabic text prevails.

• Art. 27: exemption from income tax for ten years from the date the activity commences, renewable for two similar periods, for qualifying activities.
• Art. 28: goods are exempt from customs taxes when introduced into the zone, and may not be disposed of for purposes other than those for which they were imported without the authority’s approval and payment of the customs taxes due.
• Art. 8: capital may be wholly owned by non-Omanis, for operators, enterprises and real estate developers.
• Art. 9: the board may exempt an enterprise or a real estate developer from the minimum capital requirement.
• The decree repeals the Free Zones Law issued by Royal Decree 56/2002, and preserves the advantages, incentives, exemptions and guarantees already granted to existing operators and working companies until their periods expire.

Read the tax point alongside the zone pages and a gap appears. Duqm and Al Mazunah still publish 30 years. Salalah still publishes 30 years. Sohar’s own rules describe ten years renewable to a maximum of twenty-five. The 2025 law describes ten renewable twice. These are not necessarily in conflict, because the older figures may sit on grandfathered agreements, but they are not the same promise either.

Because the form list overlaps so heavily, the questions that matter are the ordinary ones: how many owners, whether a parent company will hold the shares, who signs, and whether the entity needs to outlive its founder. Those are the same questions you answer for a mainland company, and we cover them in the legal-form comparison linked from this page.

One point does differ. A zone registration is tied to the zone. Sohar’s Art. 18 makes the tax exemption conditional on the company being registered in the working companies register, holding a licence, holding a lease or investment agreement with the operating authority, and conducting its activity within the zone. The entity is not free-floating; it is attached to a plot.

• Decide the owner count and owner type first; the answer is the same on either route.
• A foreign parent will need its corporate documents legalised for either route.
• A branch is available in the zones and on the mainland, but the conditions differ.
• Banking still has to be arranged separately, and a bank forms its own view of the business.

If you have not settled the structure yet, settle it before you settle the location. It is easier to move a decided structure between two locations than to reverse-engineer a structure out of a location you have already paid for.

This is where free-zone quotations most often understate the cost. The registration fee is the small number. The land, warehouse, office or flexi-unit, the service charges, the utilities, the fit-out and the environmental approvals are the large ones, and they recur. A mainland company’s premises requirement is usually whatever the activity genuinely needs, which for a services business can be modest.

• Sohar Art. 15: the licence runs for one calendar year and is renewed only if the licence and the lease are valid and all financial obligations to the operating authority are paid.
• Sohar Art. 18: the tax exemption requires a lease or investment agreement and activity conducted inside the zone.
• Sohar Art. 17: a working company may sub-let plots or facilities, subject to conditions.
• Duqm: land usufruct agreements up to 50 years, renewable, with an on-site passport and residence department and visas processed in five working days.
• Ask for the full recurring schedule, not the first-year figure, before comparing anything.

Model three years of occupancy cost on both routes. That single exercise reverses more location decisions than any tax comparison, because the incentive is conditional and deferred while the rent is certain and immediate.

This is the part of the free-zone story that competitor pages leave out, and it is published in the zone’s own rules. The ladder at Sohar reads as follows, from Arts. 19 and 24 of the Rules and Regulations read on 14 September 2026.

Compare that with the mainland position we publish elsewhere on this site: corporate tax at 15%, with a conditional 3% rate for qualifying small enterprises, payable on profit and with no Omanisation cliff attached to the rate itself. A 15% rate you understand can be cheaper to live with than an exemption you might forfeit in year four because hiring did not go to plan.

Filing does not stop either. Sohar Art. 22 requires audited accounts, and Art. 24 requires an annual tax statement listing employees and the achieved Omanisation percentage. Exempt is not the same as excused.

The reduced percentage is a genuine free-zone advantage, and for a labour-heavy industrial project it can be worth more than the tax line. It is also the condition on which the tax line depends at Sohar, which is why the two should never be assessed separately.

On visa numbers, be careful with what you read elsewhere. We could not find a published formula in any zone source that converts office space or capital into a fixed visa quota. What Sohar publishes, at Art. 2, is that the operating authority determines the number of foreign workers within a working company in a way that suits the nature of its activity. That is a judgement by the operator, not an arithmetic entitlement.

• Sohar: Omanisation not less than 15% for the first ten years, then 25%, 35% and 50% for renewals.
• Al Mazunah: 20% for the operating company, per Madayn.
• Al Mazunah also permits a Yemeni workforce to work in the zone without Oman entry visas or residence permits, which is the zone’s most distinctive feature.
• Duqm: rates set by the zone authority’s board; the percentage was not published on the page we read.
• Mainland: set by the Ministry of Labour, by activity and company size, and reviewed periodically.

If your plan depends on a specific headcount of foreign staff, ask the operator for the number in writing as part of the application, and treat any quota quoted to you by an intermediary as unconfirmed until the operator says it.

The logic is the customs-territory definition from Sohar’s rules quoted earlier: everything inside Oman except the free zones. Goods in your zone warehouse have not yet been imported into Oman in the customs sense. They are imported at the moment they cross into the customs territory, and that is when duty becomes payable.

• Foreign goods into the zone: exempt on entry.
• Zone to export markets: exempt, which is the zone’s core purpose.
• Zone to an Omani mainland customer: this is the entry into the customs territory, and duty is assessed then.
• Zone to another GCC state: Oman has been in the GCC customs union since 2003, but a free zone does not by itself confer GCC origin, so treatment depends on the goods and the processing done.
• Restricted or prohibited goods remain restricted or prohibited. Duqm publishes freedom to import without prior approval except for banned and controlled items such as explosives.

The commonly quoted figure for the GCC common external tariff is 5% of CIF value, with higher and lower rates for particular categories. We have not verified the rate for any specific product here, because it depends on the HS code and the current unified tariff. What is verified is the principle: entry into the Omani market is a duty event.

This is the single most practical difference between the two routes, and it is the one a reader most needs stated plainly. If your revenue comes from customers inside Oman, a free zone puts a customs border between you and your own market, and you pay to maintain it. If your revenue comes from outside Oman, that same border is an advantage you would otherwise have to manufacture.

You will often read that a free-zone company must appoint a mainland distributor or open a mainland branch to sell locally. We could not verify that as a rule from any official source, and what we did find points the other way in one respect: Sohar Art. 16, Duqm and Al Mazunah each publish an exemption from the Commercial Agencies Law, which is the law that would otherwise force a registered agent. So treat the distributor requirement as unconfirmed, and treat the customs charge as confirmed.

• Confirmed: duty is assessed when goods move from the zone into the Omani market.
• Confirmed: free-zone enterprises at Sohar, Duqm and Al Mazunah are published as exempt from the Commercial Agencies Law.
• Unconfirmed: that a mainland distributor or branch is legally required to sell locally.
• Practical: many free-zone businesses use a mainland entity for local sales anyway, which means running and paying for two companies.
• For services rather than goods, ask the zone directly how local supply is treated, because the customs analysis does not transfer cleanly.

If you are being sold a free zone for a business whose customers are in Muscat, ask the seller to explain this paragraph. The answer will tell you a great deal about who they are working for.

The sequence at Sohar, from Arts. 11 to 15 of its Rules and Regulations, is a useful model for what any zone application involves, even though each zone runs its own process.

• Submit the licence application form with the required documents, plus the plot application form or lease application form.
• Complete any missing documents within 15 business days of being notified, or the application is treated as cancelled (Art. 14).
• The operating authority decides within 15 business days of complete documents, with extra time possible for environmental studies (Art. 13).
• Register in the working companies register; the licence issues once fees are paid and specifies the permitted activities (Art. 11).
• The licence runs for one calendar year and is renewed annually against a valid lease and paid obligations (Art. 15).
• A separate licence is needed for each activity if you want to conduct more than one (Art. 10).

Note what the published timeline measures. It starts when your file is complete, not when you first make contact, and it does not include negotiating the lease, arranging the facility, or opening a bank account. Anyone quoting you a total elapsed time for free zone company setup in Oman should be asked which of those stages the quote includes.

For reference, our published mainland formation packages start at OMR 980, and that figure covers the scope stated on our packages page. We deliberately do not publish a free-zone comparison price, because we do not provide the service and any number we invented would be marketing rather than information. Zone fee schedules are published by each operator; Sohar’s rules refer to an attached fee schedule rather than setting fees in the text.

• Year one: registration, licence, lease deposit and first rent, fit-out, environmental permits, legalised documents.
• Every year after: licence renewal, rent and service charges, utilities, audited accounts, tax statement with Omanisation reporting.
• Conditional: the hiring required to hold the Omanisation percentage that the tax exemption depends on.
• Operational: duty on anything you sell into the Omani market, and the cost of any second entity you need for local sales.
• On the mainland: formation, premises appropriate to the activity, licence renewals, and tax at 15%, or 3% if the small-enterprise conditions are met.

Do the arithmetic over three years rather than one. An exemption that begins delivering value in year two and is conditional on year-by-year hiring is a different financial object from a rate you can calculate today, and the comparison should show that rather than hide it.

Where the table says mainland, that is a route we can act on for you. Where it says free zone, it is a route we will explain and then hand to the zone operator, because we do not provide free-zone formation and will not pretend otherwise to keep the enquiry.

If your business sits between two rows, the deciding question is the one from the top of this page: what proportion of your revenue comes from customers who take delivery inside Oman? Answer that honestly and the route usually chooses itself.

We publish this page for a commercial reason worth stating openly. A good proportion of people who arrive convinced they need a free zone actually need a mainland company, usually because their customers are Omani, and they have been told otherwise by a firm that sells both and earns more on one. Getting that diagnosis right is useful to you whether or not it ends with us.

• Free-zone or special-economic-zone registration: apply to the zone operator or OPAZ. We cannot act.
• Mainland formation, including full foreign ownership under Royal Decree 50/2019: packages from OMR 980.
• Working out which of the two you need: we will do that with you at no charge, and say so plainly if the answer is a free zone.
• Tax, VAT and corporate banking on the mainland: covered in the guides linked from this page.
• Zone incentive confirmations, lease negotiation and zone licensing: the operator, not us.

If you want a second opinion on a free-zone proposal you have already been sent, send it over. We will tell you which claims in it we can trace to a zone authority and which we cannot, which is a shorter conversation than it sounds and often a useful one.
