UAE Mainland vs Free Zone: Legal and Tax Differences

UAE company law reforms allow 100% foreign ownership for a broad range of Mainland activities. A Free Zone structure is therefore no longer necessary merely to preserve full foreign ownership and control. Activities with strategic impact, however, remain subject to specific ownership restrictions, approvals and regulatory requirements. 

The tax distinction is also more nuanced than the proposition that Mainland companies are taxed at 9% while Free Zone companies are taxed at 0%. A Free Zone Person remains within the Corporate Tax framework. The 0% rate applies only to Qualifying Income of a Free Zone Person that satisfies the conditions for Qualifying Free Zone Person (QFZP) status. 

For a broad range of UAE activities, a Mainland company may be wholly owned by foreign individuals or legal entities. Federal Decree-Law No. 32 of 2021 on Commercial Companies removed the general requirement for a majority Emirati shareholder and eliminated the general requirement for branches of foreign companies to appoint a UAE national service agent. 

Full foreign ownership is not unconditional for every activity. Cabinet Resolution No. 55 of 2021 identifies activities with strategic impact for which the competent regulator may determine foreign ownership restrictions and additional licensing conditions. These include security and defence activities, banking, exchange and finance businesses, insurance, telecommunications and other specifically identified sectors. Fisheries-related services are subject to a 100% Emirati ownership requirement. 

A Free Zone should therefore not be selected solely on the assumption that it is the only structure capable of providing 100% foreign ownership. The proposed licensed activity and any applicable strategic-sector restrictions should be reviewed before incorporation. 

Under the general UAE Corporate Tax regime, Taxable Income up to AED 375,000 is subject to a 0% rate and the portion exceeding AED 375,000 is subject to a 9% rate, unless a specific regime applies. These general thresholds should not be confused with the QFZP regime. 

Free Zone Persons are also within the scope of Corporate Tax and are generally subject to registration and compliance obligations. Where a Free Zone Person satisfies all requirements for QFZP status, a 0% Corporate Tax rate applies to Qualifying Income, while Taxable Income that is not Qualifying Income is subject to 9%. The general AED 375,000 0% band does not apply to the non-qualifying Taxable Income of a QFZP. 

QFZP status requires the cumulative satisfaction of the statutory conditions. These include maintaining adequate substance in a Free Zone, deriving Qualifying Income, complying with the arm's length principle and applicable transfer pricing requirements, satisfying the de minimis requirement and complying with the applicable audited financial statement requirements. The scope of Qualifying Activities and Excluded Activities must be determined under the legislation currently in force. Ministerial Decision No. 229 of 2025 replaced Ministerial Decision No. 265 of 2023 and updated the relevant activity framework. 

The de minimis requirement is satisfied only where non-qualifying Revenue does not exceed the lower of 5% of total Revenue for the relevant Tax Period or AED 5,000,000. 

If a Free Zone Person ceases to satisfy any of the QFZP conditions, it loses eligibility from the beginning of the Tax Period in which the condition was breached and is taxed under the general Corporate Tax regime for five Tax Periods starting with that period. A breach of the QFZP conditions can therefore affect the entity's tax status for several years rather than merely subjecting an isolated item of income to 9% tax. 

A Free Zone licence does not, by itself, grant unrestricted access to the UAE Mainland market. Mainland access depends on the type of activity, the relevant emirate, the rules of the particular Free Zone and the local licences or approvals required for the proposed operations. Selling goods or providing services on the Mainland will generally require an appropriate licensing arrangement, a licensed Mainland distributor or another legally permissible structure. Goods transferred from a Free Zone into the domestic market are also subject to the applicable customs framework. 

Dubai has introduced an important specific regime. Executive Council Resolution No. 11 of 2025 allows Free Zone establishments to conduct certain activities outside their Free Zone and within the Emirate of Dubai, provided that the appropriate licence or permit is obtained from the Dubai Department of Economy and Tourism (DET). The available routes include establishing a branch outside the Free Zone, establishing a branch operating out of the Free Zone, or obtaining a permit for specified activities. Relevant approvals from the Free Zone licensing authority and sector regulator may also be required. The regime does not apply to financial establishments licensed in the Dubai International Financial Centre (DIFC). 

It is therefore no longer legally accurate to state categorically that a Free Zone company cannot operate on the Mainland. The answer depends on the emirate, the licensed activity and the availability of the required local licence or permit. 

A Mainland structure remains the more direct model where the core business requires an ongoing physical presence in the domestic market through retail premises, offices, restaurants, warehouses or other facilities outside a Free Zone. Free Zone structures are commonly used for international trade, re-export, logistics, technology businesses, holding functions and other models centred within the Free Zone or outside the UAE. The specific licence, however, is legally more important than the general Mainland or Free Zone label. 

For Mainland businesses, recruitment and work permits are generally administered through the Ministry of Human Resources and Emiratisation (MOHRE) together with the competent immigration authorities. There is no universal UAE rule allocating a fixed number of square metres of office space to each employment visa. MOHRE considers factors including the legal status of the business, the size and nature of its workplace, its projects and its actual workforce requirements. 

For Free Zone entities, work permit and residence procedures are generally handled through the relevant Free Zone Authority. Visa capacity depends on the specific Free Zone, the selected package, the type and size of premises and the rules of the relevant authority. DIFC and Abu Dhabi Global Market (ADGM) operate separate employment regulatory frameworks. 

There is therefore no single office-space, visa-quota or workforce model that applies uniformly to all UAE Free Zone entities. 

The Mainland versus Free Zone decision cannot be separated from the licensing regime applicable to the proposed activity. Financial services, virtual assets, healthcare, pharmaceuticals, education and other regulated professions may require additional licensing or regulatory approval regardless of the corporate form selected. 

For virtual assets in Dubai, the Virtual Assets Regulatory Authority (VARA) is the regulatory authority across the Dubai Mainland and its Free Zones, except within DIFC. Financial services involving Crypto Tokens in DIFC are regulated by the Dubai Financial Services Authority (DFSA), whose updated Crypto Token framework has been in force since 12 January 2026. 

ADGM operates a separate financial regulatory framework under the Financial Services Regulatory Authority (FSRA), including dedicated rules for virtual and digital asset activities. The FSRA further updated its virtual asset, fiat-referenced token and staking frameworks during 2025 and 2026. 

For a regulated business, the analysis should therefore begin by identifying the competent regulator and the licence required for the proposed activity rather than by comparing incorporation costs or headline tax rates. 

Mainland or Free Zone status does not, by itself, guarantee that a corporate bank account will be opened or that onboarding will be easier. UAE financial institutions apply a risk-based approach to customer due diligence and beneficial ownership verification. 

For a corporate customer, a bank may examine the trade licence and incorporation documents, ownership structure, ultimate beneficial owners, nature of the business, expected account activity, source of funds and, where relevant, source of wealth. The intensity of the review depends on the individual customer and business risk profile rather than solely on the jurisdiction in which the company is incorporated. 

In practical terms, genuine economic activity, transparent ownership, a coherent business model and documentary support for expected transactions are relevant to banking onboarding for both Mainland and Free Zone companies. 

Establishing a UAE company does not displace the application of Bulgarian tax legislation or the Bulgaria-UAE Double Tax Treaty. The treaty has been in force since 16 November 2008. 

For the purposes of Article 5 of the treaty, a place of management and an office are among the examples of a permanent establishment where the relevant conditions are met. Separately, the provision of services, including consultancy services, through employees or other personnel may create a permanent establishment where activities relating to the same or a connected project continue for more than nine months within any twelve-month period. The nine-month threshold applies to this service permanent establishment rule and should not be treated as a threshold applicable to the general fixed-place permanent establishment test. 

Article 10 of the treaty limits source-state taxation of dividends to 5% of the gross dividend where its conditions are met and the beneficial owner is a resident of the other Contracting State. This is a treaty maximum rather than an automatically applicable tax rate. Under the UAE Corporate Tax legislation currently in force, the withholding tax rate applicable to the relevant UAE-sourced income of a Non-Resident Person that is not attributable to a Permanent Establishment or other applicable nexus is currently 0%. 

Bulgarian taxpayers must also consider the controlled foreign company rules under Articles 47v and 47g of the Bulgarian Corporate Income Tax Act. For a foreign entity, the control test includes a direct or indirect participation exceeding 50% of voting rights, capital or entitlement to profits, held by the taxpayer alone or together with its associated enterprises, together with a separate test concerning the Corporate Tax actually paid by the foreign entity. 

The application of a 0% rate to Qualifying Income in the UAE may make the Bulgarian CFC analysis relevant, but it does not automatically make the UAE entity a controlled foreign company for Bulgarian tax purposes. All statutory conditions must be examined. Article 47g(7) of the Bulgarian Corporate Income Tax Act also excludes the adjustment under Article 47g(1) where the controlled foreign company carries on substantive economic activity supported by the personnel, equipment, assets and/or premises necessary for that activity and the taxpayer substantiates those circumstances. 

Transactions between related Bulgarian and UAE entities are also subject to the arm's length principle. Bulgarian transfer pricing rules apply to transactions between related parties, while mandatory Local File and Master File documentation applies to enterprises falling within the statutory scope of Article 71b of the Bulgarian Tax and Social Security Procedure Code. From 1 January 2026, Ordinance No. H-3 of 7 November 2025 governs the methods for determining arm's length prices in Bulgaria. 

A Mainland structure will generally be more suitable where the core business requires direct and continuing operations in the UAE domestic market, physical premises outside a Free Zone, local staffing and an unrestricted onshore operational model within the scope of the relevant licence. For a broad range of activities, Mainland companies can be 100% foreign-owned, subject to sector-specific restrictions and approvals. 

A Free Zone structure may be appropriate for international trade, re-export, logistics, technology businesses, holding functions and other activities associated with a specialised Free Zone. It does not automatically guarantee a 0% Corporate Tax rate, unrestricted Mainland market access or simplified banking and regulatory compliance. 

Where the business model relies on the QFZP regime, the structure should be capable of satisfying the Qualifying Income, adequate substance, de minimis, transfer pricing and other compliance requirements on an ongoing basis rather than merely at the time of incorporation.
