Mauritius and Dubai are both established, well-regulated bases for international business, but they are not interchangeable. The choice between them should follow your business model, not an assumption that one is simply cheaper or more tax-efficient than the other. Dubai sits at the centre of the Gulf and Middle East, has no personal income tax, and suits founders who need a regional base close to Gulf clients, banking and logistics.
Mauritius sits between Africa and Asia, operates as a regulated international financial centre supervised by the Financial Services Commission (FSC), and gives access to a treaty network of 45 double taxation agreements in force (MRA, 2026), relevant for structures investing into Africa, India or other treaty partner countries. Corporate tax works differently in each jurisdiction: the UAE applies a 9% rate above AED 375,000, with 0% available to a Qualifying Free Zone Person on qualifying income, subject to conditions; Mauritius applies a 15% standard rate, and a Global Business Company can access an 80% partial exemption on specified foreign income where substance conditions are met. For individuals the contrast is sharper: the UAE has no personal income tax, while Mauritius applies progressive personal tax up to 35%, and a UAE resident who becomes tax resident in Mauritius is taxed on Mauritius income and on foreign income remitted there.
The sections below compare tax, residency, treaty access, substance, costs and banking, and set out when founders use both jurisdictions together.
Different Strategic Purposes
Dubai and Mauritius are not competing on the same axis, and treating the choice as simply a matter of cost misses the point. Dubai functions as a regional hub for the Gulf and the wider Middle East: no personal income tax, strong logistics and banking infrastructure, and proximity to clients and suppliers across the region. Businesses trading with Gulf counterparties, running a regional headquarters, or serving Gulf-based clients typically look at Dubai first. Mauritius functions as a regulated international financial centre positioned between Africa and Asia, supervised by the Financial Services Commission (FSC). It suits businesses investing into or trading with Africa, India or other Indian Ocean and Asian markets, structures that need access to Mauritius's treaty network, and individuals seeking a residence base with a different lifestyle and cost profile from the Gulf. Many founders use Mauritius alongside a UAE structure rather than instead of it, keeping Gulf operations in Dubai and using Mauritius for Africa-facing investment, holding structures or personal residence. The right choice depends on where your clients, investors and markets actually are, not on a general assumption that one jurisdiction is cheaper or simpler than the other.
Corporate Tax
UAE corporate tax is 9% on taxable income above AED 375,000, with 0% on the first AED 375,000, in place since June 2023. A Qualifying Free Zone Person can benefit from 0% on qualifying income, subject to conditions, including a de minimis limit on non-qualifying income (the lower of 5% of revenue or AED 5 million); income above that, or non-qualifying income, is taxed at 9%. Mauritius applies a standard corporate tax rate of 15%. A Global Business Company (GBC), licensed through the FSC via a management company, is tax resident in Mauritius and can access an 80% partial exemption on specified foreign income (foreign dividends, interest, profits of a foreign permanent establishment, ship and aircraft leasing income, among others), but only where substance conditions are met: core income-generating activities in Mauritius, adequate qualified staff, and expenditure proportionate to the activity. Where those conditions are met, the exemption can bring the effective rate close to 3%, though this is conditional, never automatic. An Authorised Company is instead non-resident for tax, paying tax only on Mauritius-source income. Domestic Mauritius companies trading locally pay the standard 15% rate. Both jurisdictions also apply a 15% top-up tax to large multinational groups with revenue of EUR 750 million or more.
Personal Tax and Residence
The UAE has no personal income tax, for residents or non-residents, on employment or investment income. This is one of the clearest, most consistently cited reasons founders and individuals base themselves in Dubai or another emirate. Mauritius applies progressive personal income tax: from 1 July 2026, 0% on the first MUR 500,000 of annual income, 10% up to MUR 1,000,000, 20% up to MUR 12,000,000, and 35% above that (Finance Act 2026). An individual becomes Mauritius tax resident by spending 183 days in Mauritius in the income year (1 July to 30 June), or 270 days across the current and two preceding income years, or by being domiciled in Mauritius. Once resident, foreign-source income is taxed only when it is remitted to Mauritius, which gives some planning flexibility but does not remove the underlying liability. A UAE resident who relocates to Mauritius and becomes tax resident there should expect to pay Mauritius tax on Mauritius-source income and on foreign income they bring into the country, even if that income was previously untaxed in the UAE. This is a real, material difference between the two jurisdictions and should be assessed before any move, not after.
Treaty Networks and Market Access
Mauritius has 45 double taxation agreements in force (MRA, 2026) and 46 investment promotion and protection agreements in force (EDB, 2026), built up specifically around Africa and Asia. This network is one of the main reasons investment and holding structures use Mauritius to reach African and Indian markets: a Mauritius entity can access treaty relief that a direct UAE structure investing into the same markets may not. The Mauritius-UAE double taxation agreement itself is in force (effective 1 September 2019 on the UAE side, 1 February 2020 on the Mauritius side), which is relevant where funds, dividends or services flow between the two jurisdictions. The UAE's own treaty network is extensive and geared toward the Gulf, the Middle East and its major trading partners, and suits businesses whose activity is concentrated in that region. In practice, the two networks are complementary rather than competing: a group with Gulf operations and Africa-facing investment often ends up using a UAE entity for the former and a Mauritius entity for the latter, rather than trying to cover both with one structure. Which network matters to you depends entirely on where your counterparties, investors and target markets are based.
Substance and Costs
Both jurisdictions increasingly require real substance behind any tax benefit, and neither should be presented as a place to book profit without activity. In Mauritius, a GBC seeking the 80% partial exemption must show core income-generating activities performed in Mauritius, adequate qualified staff, and expenditure proportionate to its income; falling short of these conditions puts the exemption itself at risk. In the UAE, a Qualifying Free Zone Person must likewise meet substance requirements to keep the 0% rate on qualifying income, alongside the de minimis limit on non-qualifying income. On costs, Mauritius can offer lower office, staffing and operating costs than Dubai in some situations, particularly for back-office, administrative or investment-holding functions, but this varies by activity and should never be assumed without a specific comparison for your business. Dubai's costs reflect a more built-out commercial and logistics environment suited to trading, regional headquarters and client-facing activity. Company formation and ongoing compliance in Mauritius run through an FSC-licensed management company, which handles incorporation, registered office, substance arrangements and annual filings; this adds a layer of professional oversight that is part of the regulatory model, not an optional extra.
Banking
Opening a bank account is a separate process from incorporation in both jurisdictions, and neither should be assumed to be quick or guaranteed. Mauritius banks apply standard know-your-customer and source-of-funds checks, and a company's substance, business plan and ownership structure are all reviewed before an account is opened; approval is never guaranteed and timelines vary by bank and by profile. The same is true in the UAE, where banks assess the free zone or mainland licence, the nature of the business, and the beneficial owners' documentation. For a UAE resident opening a Mauritius account, having an FSC-licensed management company handle the relationship, prepare documentation and liaise with the bank on your behalf generally makes the process more manageable, though it does not remove the bank's own discretion. Businesses operating in both jurisdictions typically need banking relationships in each, since a Dubai account does not substitute for a Mauritius one, and vice versa; treat banking as a distinct workstream in any relocation or expansion plan, to be started early and reviewed case by case rather than left until after incorporation.
When to Use Both
For many founders and families, the realistic answer is not Mauritius or Dubai, but both, used for different parts of the same structure. A common pattern keeps a UAE entity for Gulf-facing trading, regional headquarters functions or personal residence in the Emirates, while a Mauritius Global Business Company handles Africa- or Asia-facing investment, holding activity, or treaty-sensitive income flows, each entity taxed and reported according to its own rules. Families sometimes combine a UAE base for daily life with a Mauritius residence permit or property-linked residence as a second base, for lifestyle, diversification or eventual relocation. Using two structures adds administrative work, including separate accounting, banking and compliance in each jurisdiction, and, where entities interact, attention to transfer pricing and to where each company is actually managed and controlled. Whether a combined structure makes sense depends on your specific markets, ownership and family situation, and should be assessed individually rather than assumed; this is precisely the kind of case-by-case review a confidential assessment is designed to work through before anything is set up.
