Corporate Tax in Abu Dhabi: Everything Businesses Need to Know in 2026
If you run a business in Abu Dhabi, corporate tax is no longer something you can plan to deal with later. The UAE’s federal corporate tax regime has been in effect since June 2023, and by 2026, the expectation is full compliance across the board. Whether you are a sole trader, an SME, or a subsidiary of a larger group, understanding where you stand under UAE corporate tax rules is a basic requirement of operating here today.
What is Corporate Tax in the UAE?
The UAE introduced federal corporate tax through Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses [1]. This was a significant shift for a country that had not previously taxed business income at the federal level for most sectors.
The law applies to financial years beginning on or after 1 June 2023 [2]. For businesses with a calendar year financial year, the first tax period ran from 1 January 2024 to 31 December 2024, with the first return due by 30 September 2025 [3].
Corporate tax applies to juridical persons incorporated in the UAE, foreign entities with a permanent establishment here, and natural persons conducting business or professional activity in the UAE above a specified income threshold.
The Standard Tax Rate and Thresholds
The headline corporate tax rate is 9%, applied to taxable income above AED 375,000, while taxable income up to that threshold is taxed at 0% [4]. This two-tier structure was designed to protect smaller businesses while bringing the UAE in line with international tax norms.
For large multinational enterprises (MNEs), a separate layer of taxation now applies.
Through Cabinet Decision No. 142 of 2024, the UAE implemented a Domestic Minimum Top-up Tax (DMTT) [5]. It is effective for fiscal years starting on or after 1 January 2025. The DMTT aligns the UAE with the Organisation for Economic Co-operation and Development (OECD) Pillar Two framework, a global initiative designed to ensure large multinational groups pay a minimum level of tax in each jurisdiction.
It applies to multinational groups with consolidated global revenues of EUR 750 million or more in at least two of the four preceding fiscal years [6]. These groups are subject to a minimum effective tax rate of 15% on their UAE profits, with a top-up charge applied where the effective rate falls below that threshold.
For the vast majority of Abu Dhabi businesses operating as standalone entities or within smaller group structures, the 9% rate and the AED 375,000 threshold remain the relevant figures.
Who Needs to Register for Corporate Tax?
All juridical persons incorporated are required to register for corporate tax registration UAE, regardless of whether they are profitable or expect to owe any tax. This includes mainland companies, free zone entities, and businesses incorporated in financial free zones like ADGM. Foreign entities that have a permanent establishment in the UAE are also required to register.
Registration is done through the Federal Tax Authority (FTA) via its EmaraTax portal [7]. The FTA is the governing body responsible for administering, collecting, and enforcing UAE corporate tax obligations. Failing to register on time carries a fixed administrative penalty of AED 10,000, applicable to both juridical and natural persons [8].
It is worth being clear on one point: registration and tax liability are separate questions. You may register, file a return, and owe nothing. But the registration step is mandatory and non-negotiable.
What is Exempt or Outside Scope?
Several categories of person and entity fall outside the scope of UAE corporate tax or qualify for specific exemptions:
Government entities at the federal and emirate level are categorically exempt.
Qualifying public benefit entities (such as certain charitable organisations) may be exempt if they meet the conditions set out in the law and are listed in a Cabinet Decision.
Natural resource extraction businesses are subject to emirate-level taxation rather than the federal corporate tax regime.
Qualifying Free Zone Persons (QFZPs) can benefit from a 0% rate on qualifying income if they meet the required conditions. This includes maintaining adequate substance in the free zone, deriving qualifying income as defined under the law, and not electing to be subject to the standard regime. Income that does not qualify is taxed at 9%.
Free zone businesses should review their QFZP status annually, particularly given the FTA’s tightened documentation and substance guidance issued in 2026.
Key Compliance Obligations
Tax period and filing deadlines follow a standard structure. Businesses must file their annual corporate tax return within 9 months of the end of their financial year [3].
Accounting records must be maintained in accordance with UAE accounting standards and kept for at least seven years. All entities within scope must prepare financial statements that support their tax return, even those with zero tax liability.
Transfer pricing rules apply to related-party transactions. Businesses must ensure that transactions with connected persons are conducted on arm’s length terms.
For businesses with UAE revenue exceeding AED 200 million, or those forming part of an MNE group with consolidated revenue above AED 3.15 billion, formal transfer pricing documentation (Master File and Local File) is required [9]. Documentation must be provided to the FTA within 30 calendar days of a request.
What This Means for Businesses in Abu Dhabi Specifically
Abu Dhabi’s position as the capital of the UAE and home to major energy, financial, and government-linked enterprises means that corporate tax compliance sits at the centre of how the emirate does business. This is not a concern limited to multinationals.
Businesses operating within the Abu Dhabi Global Market (ADGM), the emirate’s international financial centre on Al Maryah Island, are subject to UAE federal corporate tax. Despite ADGM’s status as a financial free zone with its own civil and commercial laws, the federal corporate tax applies to entities incorporated there just as it does to mainland companies.
Abu Dhabi’s broader economic strategy, framed under Abu Dhabi Economic Vision 2030 and subsequent frameworks, has consistently emphasised diversification and alignment with international standards, including OECD-led global tax transparency initiatives.
A Practical Note for SMEs and Startups
If your business is early-stage or operating at modest revenue levels, the corporate tax framework is less burdensome than it might initially appear.
The 0% rate on taxable income up to AED 375,000 means that many small businesses will owe nothing even after standard filing.
Beyond that, Small Business Relief (SBR) provides additional support. Under SBR, resident businesses with total revenue of AED 3 million or less can elect to be treated as having zero taxable income for that period [10].
SBR is available for tax periods ending on or before 31 December 2026 [10]. This is a transitional measure, not a permanent feature of the regime. It must be actively elected through the EmaraTax portal at the time of filing.
SBR is not applied automatically, and if you miss the election for a given period, you cannot claim it retrospectively for that year.
Closing Note
Corporate tax in Abu Dhabi is a settled reality, not a pending reform. The frameworks are in place, the FTA is enforcing them, and expectations around documentation and filing are becoming stricter with each passing year.
Staying compliant requires more than a basic understanding of the rates. It requires accurate record-keeping, timely registration, and professional guidance tailored to your specific business structure.
We recommend working with a qualified tax advisor who is familiar with UAE federal corporate tax law and the specific context of operating in Abu Dhabi.
