Abu Dhabi has become one of the most attractive places in the world to base a business — combining a stable regulatory environment, deep capital, and a choice of jurisdictions tailored to almost every industry. But the first decision every founder, CFO and group treasurer faces is the same: should you set up in one of Abu Dhabi's free zones, in the Abu Dhabi Global Market (ADGM), or on the Abu Dhabi mainland? Each route carries different rules on ownership, market access, audit and corporate tax. This guide breaks down the options as they stand in 2026.
Why Abu Dhabi
Abu Dhabi is the capital of the UAE and home to sovereign wealth, major government-backed programmes and a fast-growing private sector. For businesses, it offers political and economic stability, world-class infrastructure, and a regulatory ecosystem that spans an internationally respected financial centre, specialised industrial and media zones, and a straightforward mainland licensing regime. Whichever structure you choose, the same federal framework applies for VAT and corporate tax — so the decision is really about ownership, activity, market access and regulatory fit.
The Abu Dhabi free zones at a glance
Abu Dhabi offers several free zones, each built around a sector:
Abu Dhabi Global Market (ADGM)
Located on Al Maryah Island, ADGM is Abu Dhabi's international financial centre. It operates its own English common-law framework and independent regulator (the FSRA), making it the natural home for financial services, holding companies, family offices, funds, fintech and professional firms. ADGM-registered companies are subject to robust corporate-governance and reporting standards, including statutory audit by an ADGM Approved Auditor.
KEZAD (Khalifa Economic Zone Abu Dhabi)
KEZAD is Abu Dhabi's largest industrial, logistics and trade ecosystem, positioned between Abu Dhabi and Dubai with direct access to ports and the wider GCC. It suits manufacturing, warehousing, distribution, and technology-enabled industrial operations that need scale and connectivity.
Masdar City Free Zone
Masdar City is Abu Dhabi's hub for clean technology, renewable energy, sustainability and innovation-led businesses. It attracts R&D, green-tech and companies aligning with the UAE's net-zero agenda.
twofour54
twofour54 is Abu Dhabi's media free zone, supporting production, post-production, gaming, digital content and creative businesses with sector-specific incentives and facilities.
Abu Dhabi Airport Free Zone (ADAFZ)
Adjacent to Abu Dhabi International Airport, ADAFZ serves aviation, aerospace, logistics, freight and time-sensitive trade that depends on proximity to air links.
ADGM in focus
ADGM deserves particular attention because it is where the most rigorous audit and governance obligations apply — and where many international investors expect to see a company incorporated. Its independent courts and regulator give counterparties confidence, but that comes with responsibilities: ADGM entities generally must prepare financial statements under IFRS and have them audited by a firm on the ADGM Approved Auditor register. Regulated entities face additional requirements, including an outsourced or in-house MLRO and compliance function. Getting the audit and compliance right from day one avoids costly remediation later.
Abu Dhabi mainland
An Abu Dhabi mainland licence (issued via the Abu Dhabi Department of Economic Development) is the route for businesses that want to trade directly across the UAE domestic market, take on government and semi-government contracts, and operate without free-zone activity restrictions. Recent reforms have widened foreign-ownership options across many activities, making the mainland more accessible than ever. Mainland companies still need proper books, and audited financial statements are increasingly expected by banks, regulators and counterparties.
Free zone vs mainland: how to choose
- Choose a free zone when your activity fits the zone's sector, you want 100% foreign ownership with a clear framework, and your customers are international or within the zone's ecosystem.
- Choose ADGM when you are in financial services, funds, holding structures or want the credibility of a common-law financial centre.
- Choose the mainland when you need to sell directly to the UAE market or bid for government work.
- Many groups end up with a combination — for example, an ADGM holding company over mainland and free-zone operating entities.
Corporate tax and the QFZP regime
The UAE's federal corporate tax applies across Abu Dhabi: 0% on taxable income up to AED 375,000 and 9% above that threshold under Federal Decree-Law No. 47 of 2022. Free-zone entities may qualify as a Qualifying Free Zone Person (QFZP) and retain a 0% rate on qualifying income — but only if they meet strict substance, qualifying-income and de-minimis conditions, and maintain audited financial statements. Every entity, free-zone or mainland, must register for corporate tax and file a return; QFZP status is assessed separately from registration. VAT (5%) and, where relevant, transfer-pricing documentation and the coming e-invoicing mandate apply regardless of jurisdiction.
Our UAE corporate tax guide for free zone entities sets out registration and QFZP testing step by step, and the transfer pricing guide covers disclosure of adjustments.
Audit and accounting obligations
Audit is where the jurisdiction choice bites hardest. ADGM companies must be audited by an ADGM Approved Auditor; QFZP status depends on maintaining audited accounts; and banks, investors and regulators increasingly expect audited statements from mainland and free-zone companies alike. Choosing an auditor that holds the right approvals — and can also handle your corporate tax, VAT and compliance — means one firm carries your entity from formation through every filing, with no changes as you scale.
Frequently asked questions
Which Abu Dhabi free zone should I set up in?
Match the zone to your activity: ADGM for financial services, funds, holding companies and family offices; KEZAD for industrial, logistics and trade; Masdar City for clean tech and sustainability; twofour54 for media and creative businesses; and ADAFZ for aviation, aerospace and time-sensitive logistics. If you need to sell directly into the UAE domestic market or bid for government contracts, an Abu Dhabi mainland licence is usually the better route.
Do Abu Dhabi free zone companies pay UAE corporate tax?
Yes — every Abu Dhabi entity, free zone or mainland, must register for corporate tax and file a return. A Qualifying Free Zone Person keeps 0% on qualifying income and pays 9% on non-qualifying income, provided it meets the substance, qualifying-income and de-minimis conditions and maintains audited financial statements. Income above AED 375,000 outside QFZP relief is taxed at 9%.
Does an ADGM company need an audit?
ADGM entities generally must prepare financial statements under IFRS and have them audited by a firm on the ADGM Approved Auditor register. Regulated entities face additional requirements, including an MLRO and a compliance function. Bin Ghannam has been an ADGM Approved Auditor since July 2024.
Is an audit required for an Abu Dhabi mainland company?
Mainland companies must keep proper books, and audited financial statements are increasingly expected by banks, regulators, investors and counterparties — and are required if you rely on Qualifying Free Zone Person status elsewhere in the group or fall under specific licensing conditions.
Can I hold Abu Dhabi mainland and free zone companies under one structure?
Yes. A common structure is an ADGM holding company sitting over mainland and free-zone operating entities, giving common-law governance at the top with domestic market access below. Each entity still registers for corporate tax and is tested for QFZP status separately.
How long does it take to set up a company in Abu Dhabi?
Timelines vary by jurisdiction and activity, but the practical path is the same: confirm the activity and jurisdiction, reserve the name, incorporate, open banking, register for corporate tax and (where applicable) VAT, then appoint an auditor. Getting the audit and tax position right before incorporation avoids restructuring later.
