Starting a Business in the UAE: The Complete Legal Guide

Starting a business in the UAE means making a series of legal choices before you ever open your doors — where to license, which activities you're allowed to run, who can own the company, and how it will be taxed. This guide walks through the legal decisions behind business setup in Dubai and the wider UAE, from company formation to the contracts every founder should have in place.

Direct answer. There is no single "UAE company." You first choose between a mainland licence and a free zone, then a legal form — most often a limited liability company — governed by the UAE Commercial Companies Law, [Federal Decree-Law](/dictionary/federal-decree-law) No. 32 of 2021. From there you reserve a name, obtain your activity approvals and trade licence, sign the founding documents, and register for tax where it applies. The sections below unpack each step.

Mainland vs free zone: the first and biggest decision

The phrase you'll hear first in any business setup Dubai conversation is mainland vs free zone, and it shapes almost everything that follows. The two are different legal environments, not just different addresses.

A mainland company is licensed by the economic department of the emirate where it sits — for example, a Department of Economic Development. It can trade directly across the UAE's local market and bid for government work. A free zone company is set up inside one of dozens of designated zones, each with its own registrar and rules. Free zones have long allowed full foreign ownership and suit international trade and holding structures, but a free-zone company's right to sell directly into the mainland market is usually limited and may require a local distributor or agent.

Neither is universally better; it depends on who your customers are and where you'll invoice from. For a proper side-by-side, read our breakdown of how mainland and free-zone setups compare.

Trade licences and business activities

Every UAE business runs on a trade licence, and the licence is tied to specific approved business activities. You don't simply register "a company" — you register a company permitted to carry out a defined list of activities, and you must operate within that list.

Licences generally fall into commercial, professional, or industrial categories, with the right one determined by what you actually do. Some activities need extra approvals from sector regulators before the licence is issued — regulated fields such as financial services, healthcare, legal services, and education are common examples.

Because activity classifications and approval requirements are updated periodically, check the current rules for your exact activity. The UAE government's official portal at u.ae is a good starting point, and the relevant economic department or free-zone authority holds the definitive activity list.

Ownership: who can own a UAE company

Who is allowed to own a UAE company is one of the most-asked questions in company formation UAE planning — and the answer changed significantly in recent years.

Company forms and ownership are governed by the UAE Commercial Companies Law, Federal Decree-Law No. 32 of 2021. The most common vehicle for trading inside the UAE is the limited liability company (LLC), in which owners' liability is generally limited to their shareholding — a concept explained further in our dictionary entry on the Commercial Companies Law. You can open the law's landing page in our legislation library.

The headline reform is foreign ownership: for a wide range of mainland activities, the old requirement for a majority Emirati shareholder no longer applies, and full foreign ownership is now permitted. Two cautions apply. First, certain strategic activities still carry ownership conditions, and that list can change. Second, free zones always allowed full foreign ownership under their own rules. Confirm the position for your specific activity before relying on any percentage.

The legal steps to register a UAE company

Once you've chosen mainland or free zone and settled your activities, company formation follows a recognisable sequence. The details differ by authority, but the legal spine is similar:

1. Reserve a [trade name](/dictionary/trade-name) that complies with UAE naming rules.
2. Get initial approval for your chosen activities, including any sector-regulator sign-offs.
3. Draft and notarise the founding documents — chiefly the Memorandum of Association for an LLC.
4. Secure premises or a compliant registered address (physical office, flexi-desk, or free-zone facility).
5. Issue the trade licence from the economic department or free-zone authority.
6. Complete post-licence steps — corporate bank account, establishment card, visas, and tax registration where applicable.

Each step carries its own document and approval requirements, and the order can shift between emirates and zones. For a Dubai-specific walkthrough, see our guide to registering a company in Dubai. Treat any timeline you read as indicative only.

Tax when starting a business in the UAE

Tax is now a core part of starting a business in the UAE, and it has two main layers.

The first is [corporate tax](/tools/corporate-tax-calculator), introduced by Federal Decree-Law No. 47 of 2022. It applies to business profits above a set threshold, at 0% on taxable income up to AED 375,000 and 9% on taxable income above AED 375,000, which you should confirm with the Federal Tax Authority. Qualifying free-zone businesses may receive specific treatment if they meet the conditions. To estimate liability once you know your numbers, use our corporate tax calculator.

The second is value-[added](/dictionary/added) tax ([VAT](/tools/vat-calculator)), governed by Federal Decree-Law No. 8 of 2017, which remains in force as amended (most recently by Federal Decree-Law No. 16 of 2024 and Federal Decree-Law No. 16 of 2025). VAT is charged at a standard rate of 5%. Businesses must register for VAT once their taxable supplies cross the mandatory registration threshold of AED 375,000, with voluntary registration available from AED 187,500. Because rates, thresholds, and reliefs are set by federal law and can change, verify the current figures with the Federal Tax Authority before planning around them.

The contracts and documents you'll need

Beyond the licence, a UAE company runs on a stack of legal documents whose quality often decides how smoothly it runs later.

The foundation is the Memorandum of Association (MOA): the contract between shareholders recording who owns what, how profits are split, how decisions are made, and who can bind the company. Where there are several founders or investors, a separate [shareholders' agreement](/dictionary/shareholders-agreement) covering exit, deadlock, and share transfers is worth having. If you employ people, you'll need employment contracts that comply with UAE labour rules.

Getting the founding documents right at the start is far cheaper than fixing them after a dispute. To sanity-check a clause or a concept in plain language before you see a lawyer, you can ask the LEXAI AI assistant — it explains the terrain, it does not replace professional advice.

When to bring in a UAE corporate lawyer

You can handle a simple setup yourself or through a formation agent, but there are moments where a licensed UAE corporate lawyer earns their place: choosing between mainland and free zone when the trade-offs are close; drafting an MOA and shareholders' agreement that genuinely protect you; and confirming foreign-ownership and licensing rules for an unusual or regulated activity.

Legal input matters most when several founders are involved, when outside money is coming in, or when your activity is regulated.

When you're ready, you can compare corporate and commercial lawyers across the UAE in the LEXAI lawyer directory and contact them directly — you deal with the lawyer on your own terms.

Frequently asked questions

Can a foreigner fully own a business in the UAE?

In many cases, yes. The UAE Commercial Companies Law was reformed so that full foreign ownership is now allowed for a wide range of mainland activities, and free zones have long permitted 100% foreign ownership within their own rules. Some strategic activities still carry conditions, and the list can change. Confirm the current position for your specific activity with the relevant authority or a licensed UAE lawyer before you rely on it.

What is the difference between a mainland and a free zone company?

A mainland company is licensed by the emirate's economic department and can generally trade directly across the local UAE market, including with government bodies. A free zone company is licensed by a free-zone authority, usually allows full foreign ownership, and suits international trade — but its ability to sell onshore is often restricted and may need a local distributor. The right choice depends on where, and to whom, you sell.

Do I need a UAE trade licence to start a business?

Yes. Almost every commercial activity in the UAE requires a valid trade licence tied to your approved business activities and issued by the mainland economic department or a free-zone authority. The category — commercial, professional, or industrial — depends on what you do. Operating without the correct licence, or outside its listed activities, can expose you to penalties, so match the licence to your real activities from the start.

How long does it take to set up a company in the UAE?

It varies widely by emirate, free zone, activity, and whether external approvals are needed, so there is no single reliable timeline, and any figure depends on your emirate, free zone, and activity — confirm it with the relevant authority. Straightforward activities with no special approvals tend to move faster than regulated ones such as financial services or healthcare. Preparing your documents, ownership structure, and activity list in advance is the main thing within your control that shortens the process.

Does my UAE business have to pay corporate tax?

The UAE introduced a federal corporate tax under Federal Decree-Law No. 47 of 2022. Whether your business pays, and at what rate and threshold, depends on your taxable income and structure — the standard rate is 9% on taxable income above AED 375,000 and 0% up to AED 375,000, which you should confirm with the Federal Tax Authority. Free-zone businesses may qualify for specific treatment if they meet the conditions. Registering correctly and keeping proper records is essential from day one.

What legal documents do I need to start a UAE company?

The core documents usually include a Memorandum of Association (and Articles where relevant), shareholder or partnership agreements, board or manager resolutions, and your trade-licence application. If you hire staff you'll also need compliant employment contracts. The exact set depends on your legal form and licensing authority. Getting the founding documents right early — especially the MOA — avoids expensive disputes later, a common reason founders involve a corporate lawyer.

Do I need a lawyer to set up a business in the UAE?

You are not always legally required to use one, but a licensed corporate lawyer helps you choose the right structure, draft an MOA and shareholders' agreement that protect you, and confirm the ownership, licensing, and tax rules that apply to your exact activity. That matters most where several founders, investors, or regulated activities are involved. You can compare UAE corporate lawyers on LEXAI and contact them directly to discuss your setup.
