Tax Consultants in Abu Dhabi: Corporate Tax Guide for Mainland, ADGM and Free Zone Businesses (2026)

Last reviewed: 30 October 2026. Prepared by the corporate tax team at SBC UAE.

Direct answer: Abu Dhabi businesses pay the same federal UAE corporate tax as the rest of the country: 0% on taxable income up to AED 375,000 and 9% above that. Returns are filed with the Federal Tax Authority (FTA) within nine months of the end of each tax period. What differs in Abu Dhabi is the business landscape. There is ADGM's financial free zone, there are industrial and logistics zones such as KEZAD, and there is a large group of government-linked and energy businesses. A good tax consultant in Abu Dhabi is registered with the FTA as a tax agent and understands the zone and sector you operate in. They give you a written scope and name the people doing your work.

Quick answers

Is corporate tax different in Abu Dhabi? No. The same federal law, rates and deadlines apply in every emirate.

Do ADGM and KEZAD companies pay corporate tax? Yes. They pay 0% only on qualifying income, and only if they meet every Qualifying Free Zone Person condition.

Are government-owned companies exempt? Not automatically. Exemption depends on the entity and the activity.

How do I check an adviser? Look them up on the FTA's list of registered tax agents.

Can a Dubai-based consultant serve Abu Dhabi? Yes. Corporate tax is federal and filed online through EmaraTax.

Is corporate tax different in Abu Dhabi?

No. UAE corporate tax is federal. It applies under Federal Decree-Law No. 47 of 2022 in every emirate, with the same rates, deadlines and penalties, and it is administered by the FTA through EmaraTax. The Abu Dhabi corporate tax rate is therefore the federal rate:

What changes in Abu Dhabi is how the rules apply to the structures common there. The sections below cover the main ones.

Corporate tax for Abu Dhabi mainland companies

Mainland businesses are licensed by the Abu Dhabi Department of Economic Development (ADDED). Since 6 June 2024, Abu Dhabi has issued a Unified Economic License with a single reference number across the mainland and free zones. Mainland companies are taxed at the standard rates. They must register within three months of incorporation if incorporated on or after 1 March 2024, and file and pay within nine months of their year end.

Points that often need advice for Abu Dhabi mainland groups:

• Related party transactions with sister companies in free zones or abroad, which must be at arm's length.

• Tax groups, where a parent owns at least 95% of its UAE subsidiaries and wants to file one return.

• Small Business Relief for businesses with revenue up to AED 3 million, available for tax periods ending on or before 31 December 2029 (Khaleej Times).

Corporate tax for ADGM entities

Abu Dhabi Global Market (ADGM) is a financial free zone with its own civil and commercial laws and regulator. Federal corporate tax still applies to ADGM entities. An ADGM entity can benefit from the 0% rate only if it qualifies as a Qualifying Free Zone Person. That means it must have adequate substance in the free zone, earn qualifying income, meet the de minimis test, comply with transfer pricing rules and prepare audited financial statements.

Common issues for ADGM businesses include:

• Fund managers and holding companies, where the mix of qualifying and non-qualifying income must be tested carefully.

• Regulated financial services, where some activities, such as banking and many insurance activities, are excluded activities that cannot earn qualifying income.

• Substance, because a 0% rate requires real people and decision-making in the free zone.

• Group transactions with mainland entities, which are usually non-qualifying and taxed at 9%.

The FTA's Free Zone Persons guide explains the conditions with examples. For audits, the ADGM Registration Authority has confirmed that ADGM registered auditors may audit the financial statements of ADGM taxable persons for corporate tax purposes.

Corporate tax for KEZAD, Khalifa Port and other Abu Dhabi free zones

Abu Dhabi has several free zones serving industry, logistics, clean technology and media, including KEZAD, the Khalifa Port free trade zone, Abu Dhabi Airports Free Zone, Masdar City Free Zone and twofour54.

Some Abu Dhabi areas are Designated Zones for VAT purposes. The FTA's list has included the Free Trade Zone of Khalifa Port, Abu Dhabi Airport Free Zone and Khalifa Industrial Zone (Gulf News). The FTA's Designated Zones VAT guide explains how these zones work and where the current list is published. Confirm your zone's current status before relying on it. This matters for corporate tax too. From tax periods starting on or after 1 January 2026, FTA Decision No. 6 of 2026 requires Qualifying Free Zone Persons that distribute goods in or from a Designated Zone to obtain an agreed-upon procedures report from an independent auditor (Deloitte summary).

For research-led companies in Masdar City and elsewhere, the R&D tax credit applies to tax periods beginning on or after 1 January 2026, subject to pre-approval from the Emirates Research and Development Council (Deloitte summary).

Government-linked and energy businesses in Abu Dhabi

Abu Dhabi has many government-owned and government-linked businesses, and a large energy sector. The corporate tax law has specific rules for both.

• Government entities are exempt.

• Government controlled entities can be exempt for their mandated activities if they are listed in a Cabinet Decision. Their other activities, and their subsidiaries, may be taxable.

• Extractive and non-extractive natural resource businesses can be exempt from federal corporate tax if they meet the conditions in the law, including being subject to emirate-level taxation.

• Suppliers, contractors and joint ventures working with these entities are normally taxable at the standard rates.

• Wholly government-owned UAE companies may still have registration duties. Exemption should be confirmed in writing.

These distinctions are where Abu Dhabi groups most often need specialist advice. A wrong assumption about exemption can mean missed registration, missed returns and penalties.

Worked example: an Abu Dhabi group with mixed entities

An Abu Dhabi family group has three UAE companies: a mainland trading company licensed by ADDED, a KEZAD manufacturing company, and an ADGM holding company that owns both. The figures are illustrative.

The mainland company's tax is 9% of AED 2,625,000, which is AED 236,250. Two points matter in practice. First, sales by the KEZAD company to its mainland sister company are generally not qualifying income. If they exceed the de minimis limit, the KEZAD company can lose the 0% regime altogether. Second, the price between the two companies must be at arm's length, or the FTA can adjust it. A tax group is not available here, because a Qualifying Free Zone Person cannot join one. These are exactly the questions an experienced corporate tax consultant should raise in the first meeting.

Preparing for your first meeting with a tax consultant

• Trade licences for every entity, whether ADDED, ADGM, KEZAD or another zone.

• Memoranda and articles of association, and a group structure chart.

• Latest financial statements, audited where available.

• A list of transactions between group companies and with owners.

• Your corporate tax registration numbers and EmaraTax access.

• Any FTA correspondence, including penalties or queries.

• Details of government ownership or exemption claims, if relevant.

With these in hand, a good adviser can give you a clear view of your exposure in a single meeting, and a realistic plan and fee for fixing any gaps before your next filing deadline.

How to choose tax consultants in Abu Dhabi

Step 1: Verify FTA registration

Ask for the tax agent registration numbers of the firm and the individual who will sign your return. Check them on the FTA's list of registered tax agents, which you can filter to Abu Dhabi and to agents with corporate tax experience. The FTA's tax agent requirements include a relevant degree, at least three years of recent experience, fluency in Arabic and English, an FTA exam and professional indemnity insurance.

Step 2: Check knowledge of your zone and sector

Ask how corporate tax applies to your licence, whether that is ADDED mainland, ADGM, KEZAD or another zone, and to your sector. An adviser who has worked with ADGM funds or KEZAD manufacturers will raise the right issues early.

Step 3: Ask questions with checkable answers

• "Can our free zone entity be a Qualifying Free Zone Person, and what is the de minimis limit?" Expect the lower of 5% of revenue or AED 5 million.

• "Are we exempt as a government controlled entity, or only for some activities?" Expect a careful answer that refers to the Cabinet Decision listing.

• "Do our related party transactions need a transfer pricing disclosure?" Expect questions about transaction values.

• "If we registered late, how do we have the penalty waived?" Expect filing the first return within seven months of the end of the first tax period.

Step 4: Agree scope and fees in writing

The engagement letter should state the entities and periods covered, whether the firm files as your agent, your deliverables, fees and exclusions, and support for FTA queries.

Corporate tax and VAT: why Abu Dhabi businesses should review them together

Corporate tax and VAT are separate taxes, but the same transactions drive both. This is especially true in Abu Dhabi's Designated Zones and in groups with free zone and mainland companies. Goods moving between a Designated Zone and the mainland have VAT consequences. The same flows decide whether a free zone company's income is qualifying for corporate tax. Inter-company charges must be invoiced correctly for VAT and priced at arm's length for corporate tax. An adviser who looks at both together can spot mismatches before the FTA does. Examples include revenue in the corporate tax return that does not reconcile to VAT returns, or related party charges that appear in one filing and not the other. When you interview tax consultants in Abu Dhabi, ask how they reconcile VAT returns to the corporate tax return. It is a simple question that reveals how thorough their process is.

Red flags

• No FTA tax agent number, or one not on the FTA list.

• Promises of a guaranteed 0% rate.

• Claims of special access to government bodies.

• Assuming a government-linked business is automatically exempt.

• No written scope or unclear fees.

• Self-published "top 10" lists with no criteria.

Google's local results for "tax consultant near me" show firms with offices close to you. Google says it ranks these results by relevance, distance and prominence (Google Business Profile Help).
