I. INTRODUCTION
Cross-border mergers and acquisitions (M&A) have become central to global investment strategy, with the United Arab Emirates emerging as a preferred jurisdiction for structuring international deals. UAE free zones such as the Dubai International Financial Centre (DIFC) and the Abu Dhabi Global Market (ADGM) operate under distinct legal regimes that combine Common law principles with independent court systems and regulatory authorities. Their frameworks are supported by federal legislation, particularly the Federal Decree-Law No. 32 of 2021 (Commercial Companies Law), the Federal Decree-Law No. 47 of 2022 (Corporate Tax Law), and the Federal Decree-Law No. 36 of 2023 (Competition Law), which collectively shape the structuring and compliance landscape for cross-border transactions.
These legal instruments govern corporate restructuring mechanisms, shareholder protections, merger control thresholds, foreign investment participation, and tax obligations. In addition, free zone regulations provide statutory merger provisions, redomiciliation options, and participation exemptions that enhance transactional flexibility. However, the introduction of corporate tax and the UAE’s alignment with OECD global minimum tax standards have redefined the calculus for investors. This article critically analyses howdiscusses how structuring choices, regulatory compliance requirements, and evolving tax frameworks interact in cross-border M&A conducted through UAE free zones, highlighting both their competitive advantages and emerging constraints.
II. OVERVIEW OF UAE FREE ZONES AND THEIR STRATEGIC ROLE IN CROSS-BORDER M&A
The UAE’s free zone environment is one of the country’s major economic strengths, specifically designed to attract foreign direct investment through its legal frameworks and autonomy. Essentially, free zones are geographic areas where foreign investors are allowed to fully own their businesses without the need for a local Emirati partner, all profits can be repatriated, and where all taxes are exempt (Zero or reduced tax rates within defined frameworks). The main goal of free zones is to serve as specialised platforms that facilitate trade, innovation, and a stable legal framework for global capital.
Free zones can be generally classified into two types. Financial Free Zones, such as the Dubai International Financial Centre (DIFC) and Abu Dhabi Global Market (ADGM), are "offshore" common law jurisdictions in the UAE. They have their own independent judicial systems and English-language laws, i.e., their own statutes based on common law, and are therefore the zones of choice for high-stakes M&A and private equity transactions. On the other hand, Commercial Free Zones, such as Jebel Ali Free Zone (JAFZA) and Dubai Multi Commodities Centre (DMCC), are centred on logistics, commodities, and industrial trade and offer the infrastructure required for physical cross-border transactions.
The strategic importance of these zones is embedded in their special legal treatment. Under Article 5 of Federal Law No. 32 of 2021 on Commercial Companies, free zones enjoy autonomous regulatory systems and are exempted from federal commercial laws to the extent that free zone-specific legislation is applicable.
In the context of M&A, these zones are of paramount importance. UAE has a redomiciliation regime for foreign companies, which makes it possible for a corporation to transfer its seat of incorporation from a foreign jurisdiction to a free zone such as ADGM without changing its identity or history. This is the reason behind the implementation of cross-border transactions, which use these zones as a neutral and tax-efficient platform to consolidate capital and manage international subsidiaries under one umbrella
III. Key Legal Framework Governing Cross-Border M&A in UAE Free Zones
Cross-border M&A in UAE Free Zones is primarily governed by a hybrid framework of federal laws and specialised zone-specific regulations, notably DIFC/ADGM.
A. Federal Legal Framework
The foundation of business operations in the UAE is based on Federal Decree-Law No. 32 of 2021 on Commercial Companies (CCL). This law regulates the entire life cycle of commercial companies, from incorporation to liquidation. The most important explanation for M&A lawyers is in Article 5, which defines the territorial scope: "The CCL shall not apply to free zone companies concerning the matters regulated by their respective internal regulations." Nevertheless, following the latest amendments made by Federal Decree-Law No. 20 of 2025, free zone companies are now officially recognised as having UAE nationality and must, therefore, abide by federal law if they open branches or operate in the "mainland" (onshore) UAE.
The CCL has been modernised to permit enhanced flexibility in share classes and shareholder arrangements, allowing drag-along and tag-along rights to be embedded within constitutional documents as per Article 14. Special Purpose Acquisition Companies (SPACs) in the UAE are regulated structures that are incorporated to raise capital through an IPO on exchanges such as the Abu Dhabi Securities Exchange (ADX) to acquire private companies in 18-24 months. The impact of these changes is significant because they enable majority and minority shareholders to determine the exit process through the Memorandum of Association of the company, thus limiting the need for side agreements and offering a clearer framework on a takeover or exit.
Complementing this, there is also Federal Decree-Law No. 47 of 2022 concerning the Taxation of Corporations and Businesses. This law imposes a 9% federal corporate tax rate, but it essentially maintains the competitive advantage of free zones. Pursuant to Article 18, a "Qualifying Free Zone Person" is eligible for a 0% tax rate on eligible income. In cross-border M&A transactions, investors can utilise free zone holding companies to consolidate worldwide profits or effectuate share transfers with minimal tax leakage, as long as they have "adequate substance" in the free zone as required by the law.
The Federal Competition Law (No. 36 of 2023) requires notification to the Ministry of Economy in the event of a merger or acquisition that leads to a dominant market position, where prescribed turnover or market share thresholds are met, as determined under the implementing regulations. Failure to notify within 90 days may result in suspension, financial penalties, or invalidation of the transaction.
Finally, the Foreign Direct Investment (FDI) framework has shifted toward total liberalisation. The repeal of the requirement for 51% local Emirati ownership for most mainland activities means that the acquisition has expanded; foreign investors can now acquire 100% of many onshore targets directly, or use a free zone entity as the acquiring vehicle. This alignment enhances investor confidence and aligns the UAE practice more closely with international standards
B. Free Zone Legal Framework
Whereas the federal framework offers a broad canvas, the financial free zones of DIFC and ADGM provide the specific legal framework necessary for complex cross-border M&A. These jurisdictions operate as autonomous common law systems, offering a degree of highly developed regulatory framework in deal-making that is unusual in civil law systems.
DIFC Legal Framework
The Dubai International Financial Centre (DIFC) operates under a comprehensive legislative framework, primarily the DIFC Companies Law (DIFC Law No. 5 of 2018). This framework is distinct because it is an independent common law system. Unlike onshore entities, DIFC companies benefit from a dedicated judicial system, the DIFC Courts, which adjudicates in English and follows principles of equity and precedent familiar to global investors.
A notable illustration of this framework was the 2021 cross-border merger between UACC and UOG. The merged entity retained the name United Arab Chemical Carriers Limited. This transaction proved that the DIFC is not merely a place to hold assets but a functional jurisdiction capable of absorbing foreign entities directly, facilitating statutory mergers, where a foreign company can merge into a DIFC entity, with all assets and liabilities transferring by operation of law, thereby avoiding the cumbersome asset-by-asset transfer process. This significantly reduces transactional friction and legal uncertainty in multi-jurisdictional acquisitions.
ADGM Legal Framework
The Abu Dhabi Global Market (ADGM) takes this a step further through the ADGM Companies Regulations. While the DIFC writes its own statutes based on common law, the ADGM directly incorporates English Common Law into its legal statute via the Application of English Law Regulations 2015. The regulations also state that the English doctrine of precedent (stare decisis) is directly binding on ADGM courts. This direct adoption model enhances legal predictability and investor confidence in cross-border transactions.
IV. Strategic Importance in M&A
A. Direct Mergers (Statutory Absorption)
The ability for a foreign company to merge directly into a UAE free zone entity is a statutory mechanism that, by operation of law, transfers all assets, liabilities, and contracts by operation of law.
DIFC: Under Chapter 9 (Articles 105 to 116) of the DIFC Companies Law No. 5 of 2018, a Statutory Merger is explicitly permitted.
ADGM: Part 26 of the ADGM Companies Regulations 2020 provides a framework for mergers.
B. Holding Vehicle Efficiency (Asset Protection & Control)
DIFC Prescribed Companies: Governed by the DIFC Prescribed Company Regulations 2024.
ADGM SPVs: Established under the ADGM Companies Regulations.
C. Redomiciliation
DIFC: Articles 146 and 147 of the DIFC Companies Law 2018.
ADGM: Part 7, Chapter 2 of the ADGM Companies Regulations 2020.
V. Structuring Cross-Border M&A Through UAE Free Zones
A. The Holding Company (HoldCo) Structure
The most critical structure in contemporary UAE M&A is the HoldCo model, often established in the ADGM or DIFC. This structure acts as a neutral intermediary between a foreign parent and diverse operating subsidiaries. For instance, a foreign parent company might incorporate an ADGM Special Purpose Vehicle (SPV) under the ADGM Companies Regulations 2020, which then holds equity in operating entities across India, Europe, or the GCC.
Legal Certainty: By placing the HoldCo in a common law jurisdiction, investors ensure that shareholder agreements and exit rights are governed by already predictable principles.
Tax Optimisation: Under Article 18 of Federal Decree-Law No. 47 of 2022, a qualifying free zone HoldCo can achieve a 0% corporate tax rate on qualifying income, such as dividends and capital gains from foreign subsidiaries, provided it maintains adequate economic substance.
B. Share Purchase vs. Asset Purchase
In the UAE, the Share Purchase remains the dominant M&A method. This is largely because a share transfer in a free zone is a streamlined administrative process, typically involving a notification to the Registrar and an update to the share register. Conversely, Asset Purchases are often more considered burdensome, as they require the individual transfer of every license, contract, and employee visa.
For cross-border deals, the share purchase allows for continuity of business without the logistical hurdle of re-applying for operational permits. However, share acquisitions also transfer historical liabilities, making enhanced due diligence critical.
C. Redomiciliation and Corporate Migration
A unique strategic advantage is Redomiciliation (or corporate continuance). Unlike many jurisdictions that require a company to liquidate before moving, UAE free zones allow foreign companies to migrate their legal seat into the UAE.
Under Article 13 of the amended Commercial Companies Law (2025) and specific regulations like Part 7 Chapter 2 of the ADGM Companies Regulations 2020, a foreign entity can move its domicile into the zone while preserving its original legal identity, contracts, and banking history. This provides strategic flexibility for multinational groups seeking jurisdictional realignment without disrupting contractual continuity.
D. Joint Ventures and Minority Investment
Recent legislative reforms have greatly enhanced the flexibility of Joint Ventures (JVs). Previously, share classes were often restricted, but Article 14 and 76(4) of the 2021 CCL and similar provisions in Article 24 of DIFC Law No. 5 of 2018 now explicitly allow for different classes of shares. This enables:
Weighted Voting Rights: Founders can retain control even after significant capital raises.
Preferred Dividends: Minority investors can be granted priority in profit distributions.
Exit Mechanics: Under UAE company law (including mainland UAE, DIFC, and ADGM), drag-along rights allow a majority shareholder to compel minority shareholders to sell their shares to a third party on the same terms, while tag-along rights allow minority shareholders to join a majority’s sale and exit on equal price and conditions, typically when such rights are expressly provided in the company’s constitutional documents or shareholders’ agreement. Statutory recognition of these rights ensures that a majority shareholder can force a sale (or a minority can join one) without relying solely on contractual terms.
VI. Regulatory and Compliance Requirements
A. Corporate Approvals
Before any filing, formal corporate authorisations are mandatory. Under Article 101 of Federal Decree-Law No. 32 of 2021, a merger agreement must be approved by a majority of shareholders, subject to the voting thresholds prescribed in the company’s constitutional documents and the CCL.
Board Approval: Directors must issue a resolution approving the terms of the SPA or Merger Agreement.
Shareholder Approval: Official resolutions must be notarised (for mainland-linked deals) or digitally attested through free zone portals (like DMCC or ADGM).
Regulatory Consent: In sectors such as finance or healthcare, the relevant regulator (e.g., the Central Bank or FSRA) must issue a No Objection Certificate (NOC) before the Registrar will process the share transfer.
B. Licensing and Regulatory Compliance
Every free zone entity operates under a specific license (Commercial, Service, or Industrial). An M&A transaction often triggers a mandatory license amendment. Failing to update the license post-acquisition can lead to immediate operational freezes, including the suspension of bank accounts and visa processing quotas.
For regulated financial entities in the DIFC or ADGM, firms must follow a strict change in control notification process which is the mandatory regulatory procedure requiring prior notification and approval from the financial regulator before a person or entity acquires a specified percentage of ownership or voting power that results in significant influence or control over the firm, often requiring 30 to 60 days of advance notice to the regulator.
C. Due Diligence Requirements
Due diligence in the UAE has evolved from simple document checking to a multi-layered verification of the target’s standing through various regulations:
Corporate: Verifying the Ultimate Beneficial Owner (UBO) register as per Cabinet Resolution No. 58 of 2020. This is critical to ensure that the targeted company isn't on any international sanctions lists. Cross-border buyers must also assess exposure to international sanctions regimes and anti-money laundering compliance frameworks.
Financial & Tax: Following the UAE’s 2023 corporate tax implementation, buyers must carefully verify a target company’s VAT and Corporate Tax registration and compliance status to ensure they do not assume undisclosed past tax liabilities after the acquisition.
Regulatory: Ensuring all permits are current and that there are no pending fines from the Ministry of Human Resources and Emiratisation (MoHRE).
D. Transfer Pricing and Reporting
Under Article 34 of the Federal Corporate Tax Law (No. 47 of 2022), all related-party transactions that are common in cross-border M&A must adhere to the Arm’s Length Principle, meaning that transactions between related parties must be conducted at prices and terms that would apply between independent, unrelated parties under similar market conditions.
Documentation: Multinational groups with consolidated revenues exceeding AED 3.15 billion must maintain a Master File and Local File detailing their transfer pricing policies.
Disclosure: Even smaller entities must submit a Related Party Disclosure Form alongside their tax return if transaction values exceed specific thresholds (typically AED 40 million). This ensures that the price paid for assets or services between the foreign parent and the UAE subsidiary reflects true market value, preventing tax evasion.
VII. Tax Considerations in Cross-Border M&A Through UAE Free Zones
A. Corporate Tax Regime and QFZP Status
Under Federal Decree-Law No. 47 of 2022, the UAE applies a standard 9% corporate tax on taxable income exceeding AED 375,000. However, the strategic advantage for M&A lies in Article 18, which allows a Qualifying Free Zone Person (QFZP) to benefit from a 0% tax rate on Qualifying Income.
To maintain this status, an entity must:
Maintain adequate substance (assets, employees, and expenditure) within the free zone.
Derive income from Qualifying Activities, such as the holding of shares and other securities or treasury and financing services.
Ensure that Non-Qualifying Revenue does not exceed the threshold of 5% of total revenue or AED 5 million, whichever is lower.
B. Strategic Exemptions: Capital Gains and Withholding Tax
One major reason investors use UAE free zones in M&A transactions is the Participation Exemption under Article 23 of the Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses. This rule means that if a company owns at least 5% of another company for 12 months, the dividends it receives or the profit it makes from selling those shares are generally not taxed.
In simple terms, a free zone holding company can sell its investment or receive dividends from abroad without paying corporate tax on those amounts. Additionally, the UAE does not impose withholding tax on payments sent abroad, so dividends, interest, and royalties can be transferred to a foreign parent company without any tax being deducted at source.
C. Global Minimum Tax
In 2025, the UAE introduced a Domestic Minimum Top-up Tax (DMTT) to follow the OECD’s global minimum tax rules. From 1 January 2025, large multinational groups earning more than EUR 750 million globally must pay at least a 15% effective tax rate.
This means that while most companies in UAE free zones can still benefit from the 0% tax rate, large international groups involved in major M&A deals must now consider additional “top-up tax” if their overall tax rate falls below 15%, ensuring they meet the global minimum requirement. This reduces the relative arbitrage advantage historically associated with zero-tax free zone structures for large multinational groups.
VIII. Key Challenges and Simple Solutions in Cross-Border M&A
1. The Tax Status Trap
Issue: Many UAE free zone companies benefit from a 0% corporate tax rate. However, if they carry out too much business with mainland (onshore) UAE companies or fail to meet the required conditions, they can lose this 0% status and become subject to the standard 9% corporate tax under the Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses. If a buyer acquires a company that has unknowingly breached these rules, the buyer may inherit unexpected tax liabilities, making what seemed like a good deal significantly more costly.
Solution: Use a tax escrow arrangement. Instead of paying the full purchase price directly to the seller, a portion of the amount is placed in a secure escrow account. If the tax authority later claims unpaid taxes due to loss of free zone benefits, the funds in escrow are used to cover the liability, thereby protecting the buyer from paying out of pocket.
2. The Paperwork Stall (Merger Control)
Issue: In the UAE, when two large companies merge or when one acquires another, the transaction may need prior approval from the Ministry of Economy under competition (merger control) rules. Since the updated competition framework in 2025, the filing requirements have become stricter. If the parties fail to notify the Ministry in advance (often at least 90 days before completion, where thresholds are met), the transaction can be rejected, delayed, or penalised. This is a major reason why deals that appear commercially ready get held up for months.
Solution: Make regulatory approval a “condition precedent” in the sale agreement. Clearly state that the deal will only close once a formal No Objection Certificate (NOC) or approval is received from the authorities. Begin the filing process at least three months before the planned closing date to avoid last-minute delays.
3. The Banking Freeze
Issue: UAE banks apply strict anti-money laundering (AML) and compliance rules. When ownership of a company changes, the bank may temporarily freeze or restrict the company’s accounts until it completes updated “Know Your Customer” (KYC) checks on the new owners. For foreign or cross-border buyers, this review can take weeks, potentially disrupting payroll, supplier payments, and operations immediately after closing.
Solution: Engage with the bank early. Start the KYC and ownership update process while the transaction is still being negotiated. By informing the bank in advance and submitting required documents early, the accounts are less likely to be frozen when the ownership officially changes.
IX. CONCLUSION
UAE free zones have evolved from tax-neutral holding platforms into highly structured financial jurisdictions capable of supporting complex cross-border mergers and acquisitions. The DIFC and ADGM, in particular, provide legal certainty through common-law-based systems, streamlined merger frameworks, and internationally recognised regulatory standards. These features enhance transactional efficiency, reduce legal uncertainty, and strengthen investor confidence in multi-jurisdictional deals.
Nevertheless, the modern M&A environment in the UAE is no longer defined solely by tax advantages. The introduction of federal corporate tax, the regulatory requirements for Qualifying Free Zone Persons, enhanced merger control thresholds, and the implementation of the Domestic Minimum Top-up Tax under the OECD Pillar Two framework collectively signal a shift toward greater compliance and transparency. As a result, deal architecture must now integrate regulatory planning, tax modelling, and competition law analysis at an early stage.
Ultimately, the UAE’s competitive strength lies not merely in low taxation but in its ability to combine regulatory sophistication, legal predictability, and strategic geographic positioning. For cross-border investors, successful transactions in UAE free zones depend on careful structuring, proactive compliance, and a nuanced understanding of the evolving fiscal landscape.
