The UAE operates a layered legal system in which federal statutes, emirate-level regulations, and the independent common-law frameworks of the DIFC and ADGM apply concurrently, making precise jurisdictional analysis essential for any corporate or tax mandate.
Key takeaway
Corporate and tax practice in the UAE requires counsel to distinguish between mainland, free zone, and financial centre jurisdictions, each carrying distinct ownership rules, licensing requirements, and tax treatment. The introduction of corporate income tax in June 2023 fundamentally altered the UAE's fiscal landscape and imposes compliance obligations on virtually all juridical and natural persons conducting business. Holding structures in the DIFC and ADGM continue to offer significant legal advantages, but must be assessed against substance requirements and transfer-pricing rules. Practitioners must also track rapidly evolving economic substance, ultimate beneficial ownership, and anti-money-laundering obligations at both federal and emirate levels.
The UAE's Multi-Jurisdictional Legal Architecture
The UAE is a federation of seven emirates governed at the federal level by the Constitution and legislation enacted by the Federal National Council. Federal laws apply uniformly across all emirates unless a specific carve-out exists, while individual emirates retain legislative competence over matters not reserved to the federation, including real property and certain licensing functions.
Within this structure, the Dubai International Financial Centre and the Abu Dhabi Global Market operate as financial free zones with constitutionally recognised autonomy to enact their own civil and commercial laws, based on English common law principles. Each centre has its own court system — the DIFC Courts and the ADGM Courts respectively — with jurisdiction over disputes arising within those zones, and both courts enforce judgments reciprocally with the Dubai and Abu Dhabi onshore courts under formal recognition frameworks.
Practitioners advising on corporate or transactional matters must identify, at the outset, which legal system governs the entity, the contract, and any contemplated dispute resolution. A mainland Dubai company incorporated under Federal Decree-Law No. 32 of 2021 on Commercial Companies is subject to federal corporate law and UAE courts, while a DIFC company is incorporated under DIFC Companies Law No. 5 of 2018 and falls under English-law-influenced rules administered by the DIFC Authority.
Company Formation: Mainland, Free Zone, and Financial Centre Structures
Mainland companies in the UAE are incorporated pursuant to Federal Decree-Law No. 32 of 2021, which abolished the longstanding requirement for 51% Emirati ownership across most commercial activities. Foreign investors may now hold 100% of a mainland limited liability company in the majority of sectors, subject to a Ministerial list of strategic or restricted activities where local participation requirements remain. Professional licensing is handled at the emirate level — in Dubai through the Department of Economy and Tourism, and in Abu Dhabi through the Department of Economic Development.
Free zones number more than forty across the UAE and are administered by their own authorities, each issuing licences valid only within that zone. Free zone companies benefit from full foreign ownership, customs duty exemptions on imports into the zone, and historically no corporate tax on qualifying income. However, free zone entities wishing to transact directly with the UAE mainland must do so through a licensed mainland distributor or by establishing a separate mainland presence, which carries its own licensing and tax implications under the corporate tax regime introduced in 2023.
The DIFC and ADGM offer a distinct category of legal entity — including private companies limited by shares, foundations, and limited partnerships — governed by common-law statutes and supervised by the Dubai Financial Services Authority and the Financial Services Regulatory Authority respectively. These structures are widely used for regional holding companies, fund platforms, and wealth management arrangements because they offer contractual certainty under English-law-influenced frameworks, access to specialist courts, and recognised corporate governance standards that international counterparties find familiar.
Federal Corporate Tax: Scope and Application
Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses introduced a corporate income tax effective for financial years commencing on or after 1 June 2023. The standard rate is 9% on taxable income exceeding AED 375,000, with a 0% rate applying to income below that threshold. The tax applies to UAE juridical persons, foreign juridical persons with a permanent establishment in the UAE, and individuals conducting business subject to commercial licensing.
Qualifying Free Zone Persons may elect to benefit from a 0% rate on qualifying income, provided they meet substance requirements, do not elect to be subject to the standard regime, and derive income from transactions with other free zone persons or from qualifying activities prescribed by the Ministry of Finance. Income from transactions with mainland UAE parties generally falls outside qualifying income and is taxed at 9%, requiring free zone entities to maintain careful ring-fencing and transfer-pricing documentation.
The Federal Tax Authority administers corporate tax alongside VAT, and businesses must register, file returns, and make payments within prescribed deadlines. Ministerial decisions issued under the Decree-Law elaborate on exempt persons — including government entities and qualifying public benefit organisations — as well as the participation exemption for dividends and capital gains derived from qualifying shareholdings, which is significant for holding company planning.
Transfer Pricing and Economic Substance
Federal Decree-Law No. 47 of 2022 incorporates transfer-pricing rules requiring transactions between related parties and connected persons to be conducted at arm's length, consistent with the OECD Transfer Pricing Guidelines. Taxpayers with related-party transactions exceeding prescribed thresholds must prepare and maintain a master file, local file, and, where applicable, a country-by-country report. The Federal Tax Authority has authority to make adjustments where pricing does not reflect arm's-length terms.
Economic substance regulations, introduced federally in 2019 and subsequently amended, require UAE entities carrying on relevant activities — including banking, insurance, fund management, headquarters, holding company, intellectual property, and distribution and service centre activities — to demonstrate adequate substance in the UAE. This involves having a sufficient number of qualified employees, incurring adequate operating expenditure, and having the activity directed and managed in the UAE. Failure to satisfy the test or file the required report attracts administrative penalties.
For holding companies specifically, the substance requirement is relatively light — the entity must hold equity participations or interests, have adequate employees and premises to hold and manage those participations, and comply with annual reporting. Practitioners structuring regional or international holding arrangements through the UAE must document these requirements from inception to avoid penalties and to protect the position in treaty residence analyses.
Value Added Tax and Excise Duties
The UAE introduced VAT at a standard rate of 5% under Federal Decree-Law No. 8 of 2017 on Value Added Tax, effective 1 January 2018. Businesses with taxable supplies and imports exceeding AED 375,000 annually must register mandatorily, while voluntary registration is available below that threshold. The Federal Tax Authority enforces compliance, and penalties for late registration, late filing, and under-declaration are set out in the relevant Cabinet decisions.
Certain supplies are zero-rated, including the export of goods and services, international transportation, the supply of certain food items, and residential buildings supplied for the first time within three years of completion. Other supplies are exempt, principally bare land, residential property resales, and most local passenger transport. The distinction between zero-rating and exemption is commercially significant because input VAT recovery is available on costs attributable to zero-rated supplies but not to exempt supplies.
Excise tax, introduced under Federal Decree-Law No. 7 of 2017, applies to tobacco products, energy drinks, carbonated drinks, and sweetened beverages at rates ranging from 50% to 100% of the designated retail price. Businesses importing, producing, or releasing excise goods from a designated zone must register with the Federal Tax Authority and account for the tax at the point of entry into free circulation.
Foreign Investment Controls and Sector Restrictions
The liberalisation of foreign ownership under Federal Decree-Law No. 32 of 2021 was complemented by Cabinet Resolution No. 55 of 2021, which identified a list of activities in strategic sectors — including oil and gas exploration, utilities, telecommunications, and certain defence-related industries — where foreign ownership remains restricted or capped. Investors in these sectors must either partner with a UAE national or an entity that meets the local-ownership criteria, or seek specific ministerial approval.
The UAE maintains foreign direct investment screening under the Foreign Direct Investment Law, which establishes a committee to evaluate applications in sectors open to foreign investment above the general thresholds. Certain emirate-level incentives, such as land-lease rights and government procurement preferences, remain linked to the level of local participation, making the corporate structure decision commercially as well as legally significant.
Financial services activities conducted from the onshore UAE require a licence from the Central Bank of the UAE, the Securities and Commodities Authority, or the Insurance Authority, depending on the activity. Activities conducted from the DIFC require authorisation from the DFSA, and from the ADGM require authorisation from the FSRA. Cross-border activities — for example, a DIFC-licensed firm marketing to onshore UAE clients — require careful analysis of whether a separate onshore licence is needed to avoid unlicensed activity.
Ultimate Beneficial Ownership and Anti-Money-Laundering Compliance
Cabinet Resolution No. 58 of 2020 on the Regulation of the Beneficial Owner Procedures requires all UAE mainland companies and certain free zone entities to maintain a register of ultimate beneficial owners — defined as natural persons who ultimately own or control, directly or indirectly, 25% or more of the company's shares or voting rights, or who otherwise exercise control. This register must be filed with the relevant licensing authority and updated within fifteen days of any change.
Anti-money-laundering obligations are set out in Federal Decree-Law No. 20 of 2018 on Anti-Money Laundering and Combating the Financing of Terrorism and Illegal Organisations, as amended. Designated non-financial businesses and professions — including law firms, accountants, real estate brokers, and dealers in precious metals — are subject to customer due diligence, suspicious transaction reporting, and record-keeping obligations administered by the UAE Financial Intelligence Unit and the relevant supervisory authority.
Law firms in Dubai engaged in corporate and transactional work must therefore apply risk-based due diligence procedures to clients and matters, report suspicions to the goAML platform, and comply with targeted financial sanctions administered by the UAE's Executive Office for Control and Non-Proliferation. Non-compliance carries significant criminal and administrative penalties, and the UAE's removal from the FATF grey list in 2024 reflects the enforcement intensity that regulators have applied to these obligations.
Dispute Resolution in Corporate and Commercial Matters
Onshore UAE litigation is conducted in Arabic before the Dubai Courts or Abu Dhabi Courts, applying substantive UAE federal law supplemented by emirate-level procedural rules. Commercial disputes between companies are heard by the commercial circuits, with appeals proceeding to the Court of Appeal and then the Court of Cassation. Enforcement of foreign judgments before the UAE onshore courts requires reciprocity or a bilateral enforcement treaty; absent these, the foreign judgment may be treated as persuasive evidence rather than directly enforceable.
Arbitration is widely used in corporate contracts governed by UAE law or seated in the UAE. The UAE Federal Arbitration Law — Federal Law No. 6 of 2018 — is modelled on the UNCITRAL Model Law and provides a robust framework for domestic arbitration. The Dubai International Arbitration Centre and the Abu Dhabi International Arbitration Centre are the principal institutional arbitration bodies, while ICC, LCIA, and other institutional rules are also frequently used with a UAE seat.
The DIFC Courts offer English-language common-law litigation with judges drawn from leading common-law jurisdictions, and parties may elect DIFC Court jurisdiction by contract even without a DIFC nexus through the DIFC Courts' opt-in jurisdiction. DIFC arbitral awards and court judgments are enforceable across the UAE under the framework established by a memorandum of guidance with the Dubai Courts, and are recognised in a growing number of jurisdictions through the New York Convention on the Recognition and Enforcement of Foreign Arbitral Awards, to which the UAE is a signatory.
Selecting and Instructing a Law Firm in Dubai
Legal practice in mainland Dubai is regulated by the Dubai Legal Affairs Department, which requires practising lawyers to hold UAE Bar admission. Foreign-qualified lawyers may advise on foreign and international law within licensed foreign legal consultancy firms but may not appear before UAE onshore courts or provide formal UAE law opinions unless they hold the necessary UAE qualification and registration. In the DIFC, legal practitioners must be registered with the DIFC Authority, and the applicable framework permits foreign-qualified lawyers to advise on DIFC law.
When selecting counsel for a corporate or tax matter, clients should assess whether the firm holds the requisite regulatory approvals for the jurisdiction of the work, whether it has dedicated tax practitioners with Federal Tax Authority interaction experience, and whether its corporate team covers both transactional documentation and regulatory licensing. Conflicts of interest checks, engagement letter terms incorporating UAE professional conduct rules, and clear fee arrangements — whether fixed, hourly, or milestone-based — should be agreed in writing at the outset.
For cross-border transactions, practitioners in Dubai frequently coordinate with counsel in other jurisdictions, particularly for deals involving entities in the Cayman Islands, British Virgin Islands, Luxembourg, or Singapore. The quality of that coordination, including the management of legal opinions, condition precedent checklists, and closing mechanics across time zones and legal systems, is often the determining factor in transaction execution. Clients should confirm at instruction stage that their chosen firm has established working relationships with reliable correspondent firms in the relevant jurisdictions.
Practical checklist
- Confirm which jurisdiction — mainland, free zone, DIFC, or ADGM — governs your entity and intended activities before selecting a corporate structure.
- Register for corporate tax with the Federal Tax Authority and assess whether your entity qualifies as a Qualifying Free Zone Person under Federal Decree-Law No. 47 of 2022.
- File your ultimate beneficial ownership register with the relevant licensing authority and update it within fifteen days of any ownership change.
- Ensure your contracts specify governing law, dispute resolution mechanism, seat of arbitration, and enforcement jurisdiction explicitly and consistently.
