Family office in Dubai and Abu Dhabi: DIFC and ADGM compared

The UAE has become one of the fastest-growing family office hubs, drawing founders from the Gulf, South Asia, Europe and Africa. Families are attracted by the absence of personal income tax, a 0% corporate tax option for qualifying free zone income, long-term residence through the Golden Visa, and two financial centres — the DIFC in Dubai and ADGM in Abu Dhabi — that apply common-law frameworks, have their own courts and offer English-language legislation. Both centres sit inside the federal tax and AML system, so the choice between them is mainly about regulatory fit, thresholds, ecosystem and where the family wants to live.

In the DIFC, the Family Arrangements Regulations 2023 replaced the earlier Single Family Office Regulations and created an integrated toolkit: licensed Family Offices, a Family Business Register and recognition of Family Entities. A DIFC Family Office must serve a single family — descendants of a common ancestor not more than three generations back, together with spouses, step-children and adopted children — and the family must have aggregate net assets of at least USD 50 million at fair market value. The office is licensed by the DIFC Registrar of Companies rather than the Dubai Financial Services Authority (DFSA), and following 2023 rule changes a single family office does not register as a DNFBP. Shareholder and director details may be kept on a private register.

In ADGM, single family office activity is a controlled activity under the Commercial Licensing Regulations (Controlled Activities) Rules, overseen by the Registration Authority. The rules define a single family as all direct ancestors and descendants of an individual or a group of related individuals, including step-children and adopted children, and allow a broad range of services — concierge, HR, tax and wealth planning, investment management, legal services, holding functions and acting as trustee or foundation. Practitioners read the current conditions-of-licence rules as requiring a family net asset value of USD 10 million. Where an ADGM family office carries on regulated activities by way of business, a Financial Services Permission from the Financial Services Regulatory Authority (FSRA) is required.

Tax design deserves the most care. Under Federal Decree-Law No. 47 of 2022, a free zone family office company is a taxable person. It can benefit from 0% only as a Qualifying Free Zone Person earning qualifying income — for example holding shares, treasury and financing for related parties or its own account, and regulated fund or wealth management — and only if non-qualifying revenue stays within the de minimis limit of the lower of 5% of revenue or AED 5 million. Ministerial Decision No. 229 of 2025 now sets out the qualifying activities, replacing Ministerial Decision No. 265 of 2023. Separately, a family foundation or trust can apply to be treated as tax transparent under Article 17 of the law if it meets the Federal Tax Authority's conditions. Groups with consolidated revenue of EUR 750 million or more are also within the 15% Domestic Minimum Top-up Tax from 2025.

Strategically, the UAE suits families with business or personal ties to the Gulf, MENA, India and Africa, families relocating principals to the region, and those who want a time-zone bridge between Europe and Asia. It is often paired with a Singapore or Hong Kong office for Asian investments, or with a European trust or foundation jurisdiction where heirs live. Limitations include the newness of some regimes, evolving tax guidance, the need to evidence real substance, and the fact that UAE residence alone does not end tax residence elsewhere — home-country exit rules and controlled foreign company regimes must be reviewed before any move.
