Dubai is consistently ranked among the world’s most attractive locations for starting a business — and for good reason. The UAE capital offers zero personal income tax, zero corporate tax on most qualifying free zone companies, world-class physical infrastructure, a deeply international talent pool, and geographic positioning between European, Asian, and African markets. As of 2026, the UAE’s corporate tax (introduced at 9 percent in June 2023 for mainland companies with taxable income above AED 375,000) does not apply to free zone companies meeting qualifying conditions, maintaining the free zone model’s attractiveness for international businesses.
Mainland vs Free Zone: The Core Choice
Every business in Dubai must first decide between a mainland licence (issued by the Department of Economy and Tourism, DET) and a free zone licence. The distinction has significant operational implications.
Mainland companies can trade directly with the UAE market without restrictions, operate from any office in Dubai, and bid on UAE government contracts. Since 2021, foreign investors can own 100 percent of mainland companies in most sectors (previously capped at 49 percent for most activities), removing the historic requirement for an Emirati local partner or sponsor. Some strategically sensitive sectors — defence, oil and gas, security services — retain UAE national ownership requirements.
Free zone companies operate within designated zones (DIFC, JAFZA, DMCC, DAFZA, and over 30 others), offering 100 percent foreign ownership (long predating mainland liberalisation), duty-free import and export, and in qualifying cases, 0 percent corporate tax. Free zone companies are technically restricted from direct mainland trading without a commercial agent, though many businesses establish a free zone company for international operations and a separate mainland entity for UAE market activities.
Choosing the Right Free Zone
Dubai has over 30 free zones, each with a sector focus, fee structure, and facilities. Key ones include: DMCC (Dubai Multi Commodities Centre) — the world’s largest commodities trade hub, consistently ranked a top global free zone; DIFC (Dubai International Financial Centre) — a financial services free zone with its own common law courts and DFSA regulation; JAFZA (Jebel Ali Free Zone Authority) — adjacent to Jebel Ali Port, ideal for trading and logistics; DAFZA (Dubai Airport Free Zone) — aviation and logistics focus near Dubai International Airport; Dubai Internet City / Dubai Media City — technology and media cluster. The right choice depends on your business activity, headcount, and whether physical office space or warehousing is required.
Costs and Timeframes
Business setup costs in Dubai vary widely by licence type, free zone, and office requirements. A basic free zone licence with a virtual office (flexi-desk) starts from approximately AED 15,000-25,000 annually for a sole trader or small company. Full office space, multiple visa allocations, and sector-specific licences increase costs significantly. Mainland licences through DET start from similar levels. Professional business setup consultancies can navigate the process for a fee, and many free zone authorities offer direct setup services.
Timeline for business setup is typically 3-10 working days for free zone incorporation, slightly longer for mainland depending on approvals required. The UAE has invested significantly in digitising business registration — the process for straightforward cases is handled entirely online through authority portals.

Frequently Asked Questions
Can a foreigner own 100% of a business in Dubai?
Yes, in most sectors. Following the 2021 amendment to the Commercial Companies Law, foreign nationals can own 100 percent of mainland companies in the UAE in most business activities, eliminating the previous requirement for an Emirati partner holding at least 51 percent. Certain sectors — including defence, security, and others on a restricted list — retain UAE national ownership requirements. All free zones have allowed 100 percent foreign ownership since their establishment.
What is a UAE free zone and how does it work?
A UAE free zone is a designated economic area offering special regulatory and tax conditions for businesses operating within it. Free zone companies benefit from 100 percent foreign ownership, exemption from UAE import/export duties on goods within the zone, and (for qualifying companies) 0 percent corporate tax under the UAE’s 2023 corporate tax regime. Free zone companies are primarily designed for international trade and services rather than direct UAE market sales, though many businesses operate both a free zone and a mainland entity to capture both advantages.
