Deciding on Dubai has not decided anything yet. The emirate contains four separate systems and your licence puts you inside exactly one of them.

The case for the emirate is made one level above the decision you actually have to make

Every argument for Dubai is made about Dubai. Position between three continents, two airports and a deep-water port, a government that answers, a population that arrived from somewhere else and is comfortable doing business with people who did the same. Those statements are about an emirate, and they are broadly accurate. Our page on what the UAE actually gives you and what it costs takes the wider version of that recital apart, benefit by benefit.

The problem is that none of it is a decision. A founder who has concluded "Dubai" has settled the country, the emirate and the time zone, and has settled nothing about the company. Underneath that one name are four systems that do not share a company law, a filing office, a court or a tax test. They are not tiers of the same product. A licence in one of them is not a smaller or larger version of a licence in another; it is a different instrument issued by a different body under a different statute. If you want the route-by-route version of that choice with its costs, timeline and banking consequences worked through, that is our business setup in Dubai guide; this page stays on the narrower question of what each of the four systems actually is.

The four are the mainland, the free zones, the Dubai International Financial Centre, and the offshore vehicle. What follows is what each one actually is, and — the part that matters — the four things that change with the choice against the four that never do.

The mainland is the emirate itself, and the federal company law reaches it directly

A mainland company is licensed by Dubai's Department of Economy and Tourism. Its constitutional document is filed with the emirate, its shares move under the federal Commercial Companies Law, and a dispute goes to the onshore courts in Arabic unless the parties have written something else. Which body ends up holding that file is the decision doing the real work here, and we take that argument further in setting up in Dubai is choosing an incorporating authority.

The single most repeated claim about this route — that a foreign founder needs an Emirati partner holding a majority — has not been the general rule for some years. The requirement was removed and replaced by a defined set of activities of strategic impact where national participation is still a condition. What that means in practice is that the answer now depends on the activity rather than on the jurisdiction, which is exactly the sort of question that has to be asked before a name is reserved rather than after. Our page on the setup decisions you cannot undo later covers the ones that are expensive to revisit.

What the mainland uniquely gives you is reach. It is the only one of the four that can sell into the UAE domestic market as of right, which is the point we make from the other direction on the only UAE customer a free zone licence already reaches.

The free zones are roughly two dozen private rulebooks inside one emirate

A Dubai free zone company is not licensed by Dubai. It is licensed by the zone's own authority, under that authority's own companies regulations, and the authority is simultaneously its licensor, its filing office, its landlord and the body that decides whether a share transfer is permitted. One counterparty holds all four positions, and the concentration is easy to miss when the comparison is being run on price.

The consequence founders feel first is that the zones do not agree with each other. Share capital, director requirements, permitted activity lists, the notice a share transfer needs, what happens on a shareholder's death, whether a corporate shareholder is allowed — these are answered by a document most people never read, and the answers differ between two zones on the same road. We work one example of that divergence in full on the share capital figure is a promise, not a payment.

The second consequence is that the zones are not interchangeable in what they are built for. Some are sector clusters with a regulator inside the fence; others license almost anything and compete on cost. That distinction is the subject of a free zone is a cluster before it is a price, and it is a better first filter than the package comparison.

The DIFC is a financial free zone, and that phrase has a legal meaning rather than a marketing one

The DIFC is not a larger free zone. Financial free zones were created by a federal law that exempts them from federal civil and commercial legislation, and the centre then wrote its own: its own companies law, its own employment law, its own data protection law, its own insolvency regime, its own courts operating in English, and a financial services regulator that is not the federal one.

That is a genuine common-law jurisdiction sitting inside a civil-law country, and it is bought for specific reasons: a fund, a holding structure a foreign investor's counsel can read, a regulated financial business, a headquarters whose contracts are drafted in English and litigated in English. Our DIFC profile sets out the licence categories and what the centre costs.

It is also bought by people who do not need it, which is the honest half of the description. A trading company with UAE customers, a small consultancy, or a founder whose real objective is residence will pay for a regime built for a different problem. Whichever of the four you choose, the forum that reads your contract follows from it — and that is worth deciding deliberately rather than inheriting, which is why we wrote the court that reads your contract.

The offshore company is the one that may not trade where it was formed

Dubai's offshore vehicle is formed under the Jebel Ali Free Zone's offshore companies regulations. It is a company, it can hold assets, own shares in other companies and open a bank account, and it is commonly used to hold Dubai property in the areas the Land Department designates.

What it does not get is a trade licence to operate in the UAE. It cannot rent commercial premises to work from, it does not sponsor residence visas, and it is not a route into the domestic market. It is a holding instrument, and the mistake is buying it as a cheap version of one of the other three. Our offshore company page sets out what it can and cannot carry.

The two rows worth reading twice are the last two. Whatever a brochure implies, the bottom of that grid does not change with the choice.

Four things change, and four things never do

Change with the jurisdiction: who licenses you, whose company law your shares live under, which court is the default forum, and who has to approve a change of ownership. The mainland, free zone and offshore three of those are compared instrument by instrument in understanding the differences between mainland, free zone and offshore companies, which makes the point that only two of the three are trade licences at all.

Do not change: federal corporate tax, at 9% above AED 375,000 and 0% at or below, applies to all four — a free zone's 0% status is a status the company has to qualify for under federal instruments, not a property of the address, and no zone can confer it. VAT at 5% is federal. Anti-money-laundering and beneficial ownership obligations are federal. Immigration is federal, whichever body files the application on your behalf.

Two further points are worth stating because they are routinely garbled. A "designated zone" for VAT is a customs concept with its own list, and it is not the same set as the free zones — a company can be in a free zone and not in a designated zone. And the corporate tax law reaches the financial free zones as much as everywhere else; the exemption in the 2004 law is from civil and commercial legislation, not from tax.

Where each of the four is the wrong choice

The mainland is wrong where every customer is outside the UAE and the domestic reach is being paid for and never used.

A free zone is wrong where the customers are UAE residents walking through a door, where the activity needs a regulator that sits outside the fence, or where the real driver was a headline package price — a comparison we take apart on what a low-cost licence leaves out.

The DIFC is wrong where nothing about the business needs a common-law regime and the cost is being paid for the address.

Offshore is wrong wherever the plan involves operating, hiring or invoicing from the UAE, which is most plans.

Discovering any of these in year two is the expensive version. Moving between free zone and mainland after you have chosen sets out what the correction actually costs.

So the order to decide in is not the order the quotations arrive in. Name the customer and where they sit. Name the activity in the words a licensing authority would use. Establish whether a second authority has to approve it. Only then compare jurisdictions, and compare them on the four rows that change rather than on the annual fee. If you want a second reading of the answer, tell us who pays your invoices and where they sit — that one sentence narrows it further than any comparison table, and it is the sentence most enquiries arrive without.
