What UAE Corporate Tax Is and Who It Applies To
Federal Corporate Tax arrived in the UAE on 1 June 2023, when Federal Decree-Law No. 47 of 2022 took effect for the first financial years beginning on or after that date. For a country that had operated without corporate income tax for decades, the change was significant — and three years into its implementation, a number of misconceptions about who it applies to, how it’s calculated, and what compliance actually requires remain surprisingly common across businesses that have been operating under it from day one.
This article covers the foundational aspects of UAE Corporate Tax that every business should understand clearly: who must register, how the rate structure works, what the filing obligations are, where transfer pricing fits, and what has changed since the regime first took effect.
Fact 1 — Registration Is Mandatory for Every Taxable Person, Including Those With Zero Tax to Pay
Corporate Tax registration is a legal requirement for every entity classified as a taxable person under the UAE Corporate Tax Law — not just for businesses that expect to owe tax. A company that qualifies for Small Business Relief, a Qualifying Free Zone Person benefiting from the 0% rate on qualifying income, or a business whose taxable income falls entirely below the AED 375,000 threshold all still need to register, file returns, and maintain the records the FTA requires. The registration obligation exists independently of any actual tax liability.
Registration is completed through the FTA’s EmaraTax portal. The categories required to register include:
- Mainland entities — LLCs, civil companies, sole establishments, branches of foreign companies, and others licensed through the relevant economic department
- Free zone companies, including those that meet the Qualifying Free Zone Person conditions for a 0% rate on qualifying income
- Natural persons (individuals) carrying on business activities where their annual business turnover exceeds AED 1 million
- Non-resident persons with a Permanent Establishment or taxable nexus in the UAE
The registration deadline for businesses incorporated on or after 1 March 2024 is within 3 months of the date of incorporation. Missing this deadline triggers a fixed penalty of AED 10,000 regardless of the company’s tax position.

Fact 2 — The Rate Structure Has Three Layers, Not Two
The standard UAE Corporate Tax rate structure is well-known — 0% on taxable income up to AED 375,000, and 9% on taxable income above that threshold — but a third layer, the Domestic Minimum Top-Up Tax (DMTT), applies on top of this for large multinational groups.
The Standard Rate (Most Businesses)
Taxable income up to AED 375,000 is charged at 0%, and everything above that at 9%. These rates apply to most UAE businesses regardless of structure or location, subject to the specific rules around exemptions, reliefs, and free zone treatment described below.
The Free Zone Rate (Qualifying Free Zone Persons)
A Qualifying Free Zone Person benefits from a 0% rate specifically on qualifying income — income from transactions with other free zone persons or from permitted activities that don’t involve the UAE mainland — provided they meet the economic substance conditions, maintain adequate substance in their free zone, and satisfy all the conditions set out in the Corporate Tax Law. Income that doesn’t qualify continues to be taxed at the standard 9% rate. The 0% rate is not a blanket exemption for all free zone companies; it attaches to qualifying income from a compliant QFZP.
The Domestic Minimum Top-Up Tax (Large Multinational Groups)
For multinational enterprise groups whose consolidated annual revenue is at least €750 million, a Domestic Minimum Top-Up Tax applies under Cabinet Decision No. 142 of 2024, effective for financial years beginning on or after 1 January 2025. The DMTT tops up the group’s effective tax rate in the UAE to a minimum of 15% where it falls below that threshold. This is a separate calculation from the standard 0%/9% structure — a large MNE group needs to run both calculations, not substitute one for the other.
Fact 3 — How Taxable Income Is Actually Calculated
UAE Corporate Tax is charged on taxable income, not on turnover. Understanding how taxable income is derived from a business’s financial statements matters practically, because the adjustment process includes both additions that increase taxable income and deductions or exemptions that reduce it.
The starting point is accounting net profit — the figure in the financial statements prepared under IFRS or IFRS for SMEs. From that starting figure, a defined set of adjustments is applied:
- Non-deductible expenditures are added back — fines, bribes, dividends to shareholders, Corporate Tax itself, and 50% of entertainment expenditure incurred for external parties under Article 32
- Exempt income is excluded — qualifying dividends, participation exemption gains on disposals of qualifying shareholdings, and income of a permanent establishment abroad where a foreign tax credit applies
- Reliefs reduce taxable income — Small Business Relief (available to businesses meeting the AED 3 million revenue threshold), and loss carry-forwards from prior periods
The resulting taxable income is what the applicable rate is then applied to.
Fact 4 — Filing Requirements, Deadlines, and Penalties
Every registered taxable person must file a Corporate Tax return annually, regardless of the level of their actual tax liability. The filing deadline is 9 months from the end of the relevant tax period — for a business with a financial year ending 31 December 2025, the return and any payment due are required by 30 September 2026. There are no advance or provisional payment requirements during the year; the full liability is settled at filing.
Where a business fails to meet these deadlines, the penalty framework — restructured under Cabinet Decision No. 129 of 2025, effective 14 April 2026 — applies:
- Late registration — AED 10,000 (waivable where the business files its first return or annual declaration within 7 months of the end of its first tax period)
- Late filing — AED 500 per month for the first 12 months, rising to AED 1,000 per month from the 13th month onward, with no upper cap
- Late payment — 14% per annum, calculated monthly on outstanding tax from the day after the due date
All taxable persons must also maintain accounting records and supporting documentation for a minimum of 7 years from the end of the relevant tax period — the FTA can request these during an audit at any point within that window.
Fact 5 — Compliance Extends Well Beyond Filing the Annual Return
Submitting a return on time is the most visible Corporate Tax obligation, but it represents only part of what ongoing compliance involves.
Financial Statement Requirements
Not every business must have audited financial statements, but specific categories do. Under Ministerial Decision No. 84 of 2025, effective for tax periods from 1 January 2025, audited financial statements are mandatory for:
- Any taxable person (not in a Tax Group) whose revenue exceeds AED 50 million in the relevant tax period
- Any Qualifying Free Zone Person
- Tax Groups — all Tax Groups must prepare audited special purpose aggregated financial statements regardless of consolidated revenue, a new requirement introduced by the 2025 decision
Transfer Pricing
Transactions between related parties — or between members of the same group — must be conducted on an arm’s length basis: the same terms and pricing that would apply between unrelated parties in comparable circumstances. Businesses with material related-party transactions need to maintain documentation supporting their transfer pricing positions, since the FTA can require this documentation during a review or audit. The General Interest Deduction Limitation Rule additionally caps the deductibility of net interest expense for businesses with significant intercompany financing at 30% of EBITDA.
FTA Audit Powers
Federal Decree-Law No. 17 of 2025, effective 1 January 2026, substantially expanded the FTA’s audit powers under the Tax Procedures Law, including access to automated real-time compliance monitoring and broader investigative authority. The FTA can now conduct audits and assessments beyond the standard limitation period in certain circumstances — for example, where a refund request is under review. Maintaining complete, well-organized records from the point of registration rather than reconstructing them reactively at audit time is the most reliable way to reduce audit risk.
Voluntary Disclosure
Where an error is identified in a previously filed return, correcting it proactively through a voluntary disclosure — before the FTA identifies it independently — typically results in a more favourable outcome than having the same error discovered during an audit. Under the narrowed voluntary disclosure rules effective from 1 January 2026, formal voluntary disclosure is now reserved for errors with a material effect on the tax payable or refundable. Immaterial corrections can be made through the subsequent return without triggering the formal process.

Frequently Asked Questions (FAQs)
Who must register for UAE Corporate Tax?
All taxable persons must register, including mainland businesses (LLCs, sole establishments, civil companies), free zone companies including QFZPs, branches of foreign companies with a UAE presence, and natural persons with annual business turnover above AED 1 million. Registration is required even for businesses with zero expected tax liability.
What are the UAE Corporate Tax rates?
The standard rates are 0% on taxable income up to AED 375,000 and 9% on taxable income above that threshold. Qualifying Free Zone Persons benefit from a 0% rate on qualifying income where they meet substance and compliance conditions. Large MNE groups with €750 million or more in consolidated revenue are subject to a separate 15% Domestic Minimum Top-Up Tax under Cabinet Decision No. 142 of 2024.
When is the UAE Corporate Tax return filing deadline?
The return and any payment due must be filed within 9 months of the end of the relevant tax period. For a business with a calendar year ending 31 December 2025, the deadline is 30 September 2026.
What happens if a business files its Corporate Tax return late?
Late filing attracts a penalty of AED 500 per month for the first 12 months, rising to AED 1,000 per month from month 13 onward. Late payment of tax due is charged at 14% per annum, calculated monthly from the day after the due date.
Do all UAE businesses need audited financial statements for Corporate Tax?
No. Under Ministerial Decision No. 84 of 2025 (effective for tax periods from 1 January 2025), audited financial statements are mandatory for taxable persons with revenue exceeding AED 50 million, Qualifying Free Zone Persons, and all Tax Groups regardless of consolidated revenue. Other businesses are not required to audit, though maintaining IFRS-compliant financial statements is required for all.
What is transfer pricing and why does it matter for UAE Corporate Tax?
Transfer pricing refers to the pricing of transactions between related parties or group members. UAE Corporate Tax Law requires these to be conducted on an arm’s length basis, meaning the same terms that would apply between unrelated parties. Businesses with material related-party transactions must maintain documentation supporting their transfer pricing positions, which the FTA can request during an audit.
What is Small Business Relief and who qualifies?
Small Business Relief allows eligible resident taxable persons with revenue of AED 3 million or less in the current and all previous tax periods to elect to be treated as having no taxable income for that period, effectively paying no Corporate Tax. It cannot be claimed by businesses that are members of a multinational enterprise group or a tax group.
