Corporate Tax Basics
The Rate Structure
The UAE corporate tax applies at two rates:
0% on taxable income up to AED 375,000. 9% on taxable income exceeding AED 375,000.
This two-tier structure provides meaningful relief for smaller businesses and early-stage operations. A company with AED 500,000 of taxable profit pays 9% only on AED 125,000 — the amount above the threshold, not on the full amount.
Who Is Subject to UAE Corporate Tax?
| Entity Type | Tax Treatment |
|---|---|
| Mainland company (UAE-incorporated or UAE-resident) | 9% on taxable income above AED 375,000 |
| Free zone company — qualifying status | 0% on qualifying income; 9% on non-qualifying income |
| Free zone company — non-qualifying or tainted | 9% on all income |
| Branch of a foreign company in the UAE | 9% on income attributable to the UAE branch |
| Foreign company with UAE-sourced income | Subject to withholding tax mechanisms |
Who Is Exempt?
- UAE government entities and government-controlled entities
- Extractive businesses (oil, gas, natural resources under emirate-level concessions)
- Qualifying public benefit entities
- Qualifying investment funds meeting specific regulatory conditions
- Pension and social security funds
Tax Year and First Filing Period
The corporate tax year follows the company's financial year. For companies on a calendar year, the first taxable period was January 1 to December 31, 2024, with returns due by September 30, 2025. Companies with non-calendar financial years have their first taxable period based on the first financial year that commenced on or after June 1, 2023.
Free Zone Qualifying Status: The 0% Rate
The most consequential aspect of the framework for international businesses is the Qualifying Free Zone Person (QFZP) regime. A free zone company that meets all qualifying conditions pays 0% on its qualifying income.
The Four Qualifying Conditions
1. Adequate substance in the UAE. The company must have genuine economic substance: a real office, employed staff, and active management and decision-making occurring in the UAE. A letterbox entity will not qualify.
2. Qualifying income only. Income must derive from qualifying activities. The Ministry of Finance's list includes: trading commodities and goods, manufacturing, processing and storing goods, holding qualifying shareholdings, providing services to group companies, and shipping and logistics.
3. Adequate expense level. The company must incur adequate expenses in the UAE relative to its activities, providing further evidence of genuine substance.
4. Transfer pricing compliance. All related party transactions must be conducted at arm's length, with documentation maintained.
The Tainted Income Rule
This is the single most important rule for free zone businesses to understand.
If a free zone company's non-qualifying income exceeds 5% of its total revenue in a tax period, the company loses its QFZP status entirely for that period. All income, including what would otherwise be qualifying income, becomes taxable at 9%.
There is no partial application. The rule is binary: either you qualify on all income, or you do not qualify on any income.
| Revenue scenario | QFZP status | Tax outcome |
|---|---|---|
| 100% qualifying income | Maintained | 0% on all income |
| 4% non-qualifying income | Maintained | 0% on qualifying, 9% on non-qualifying |
| 6% non-qualifying income | Lost (tainted) | 9% on all income |
| 25% non-qualifying income | Lost (tainted) | 9% on all income |
What Disqualifies a Free Zone Company
Income from UAE mainland sources. Any income derived from transactions with UAE mainland customers is non-qualifying income.
Non-qualifying activities. Income from activities not on the qualifying activities list is non-qualifying.
Insufficient substance. If the FTA determines that your UAE presence is not genuine, qualifying status will be denied.
How to Preserve Qualifying Status
Separate your qualifying and non-qualifying activities into different entities. If you need to serve UAE mainland clients, do so through a mainland entity, keeping your free zone company's income entirely qualifying. Track your revenue mix monthly. Maintain substance documentation proactively: office lease, employment contracts, board meeting minutes, and management decision records.
Small Business Relief: The Clock Is Running Out
What It Is
A taxable person with total revenue not exceeding AED 3,000,000 in a tax period may elect to be treated as having no taxable income for that period. Zero corporate tax is payable.
Hard Deadline: 31 December 2026
Small Business Relief is available only for tax periods ending on or before December 31, 2026. There is no announced extension. From January 1, 2027, every business that has relied on this relief will enter the full corporate tax regime. If your financial year ends December 31, 2026, this is your last eligible period.
Key Conditions
- The election must be made in the tax return for the relevant period. It is not automatic.
- Revenue must not exceed AED 3,000,000 in the relevant period.
- The business must not be part of a multinational enterprise group subject to Pillar Two rules (generally, groups with consolidated revenue above EUR 750 million).
- A Qualifying Free Zone Person cannot simultaneously claim Small Business Relief. The two regimes are mutually exclusive.
What to Do Before the Deadline
| Action | Why it matters |
|---|---|
| Confirm revenue stays below AED 3M for 2026 | Eligibility is lost if threshold is breached |
| Make the election on the CT return | Non-automatic. Failure to elect = standard CT calculation applied |
| Build CT-compliant accounting for 2027 | From 1 January 2027, full compliance is required regardless |
| Assess whether to voluntarily register earlier | A compliance track record simplifies banking and future reporting |
Pillar Two: The DMTT Layer for Large Groups
What Changed in 2025
The UAE enacted the Domestic Minimum Top-up Tax (DMTT) under the OECD Pillar Two framework. It applies to financial years starting on or after January 1, 2025. For most affected groups, 2026 is the first full year of operational compliance.
The DMTT ensures that large multinational enterprise groups pay a minimum effective tax rate of 15% on their UAE profits. It applies regardless of free zone status.
Who Is In Scope
A group is in scope for DMTT if its consolidated annual revenue exceeds EUR 750 million in at least two of the four preceding fiscal years. Individual UAE entities within an in-scope group are Constituent Entities subject to the regime.
What It Requires
| Obligation | Detail |
|---|---|
| EmaraTax registration | FTA opened DMTT registration portal in 2025/2026 |
| Effective tax rate assessment | Calculate ETR per jurisdiction using GloBE rules |
| Top-up tax calculation | If UAE ETR falls below 15%, top-up applies |
| Filing deadline | 15 months after tax period end (18 months for transition year) |
Interaction with the 9% Rate
For most UAE businesses — SMEs, regional holding companies, mid-market groups — Pillar Two does not apply. The 9% rate and the QFZP regime remain the relevant framework. DMTT is relevant only to entities within large groups meeting the EUR 750 million consolidated revenue threshold.
If your group is in scope, the UAE DMTT calculation runs in parallel with the standard corporate tax computation. Both returns are filed through EmaraTax.
Compliance Requirements
Registration
All taxable persons must register with the Federal Tax Authority (FTA) and obtain a Corporate Tax Registration Number through the EmaraTax portal. The FTA has issued registration deadlines based on license issuance dates. Failure to register by the applicable deadline results in an AED 10,000 penalty.
If you have not yet registered and your business has been operational since the framework came into effect, registering now is the first priority. Voluntary registration before any FTA inquiry avoids the penalty and opens the disclosure framework benefits described below.
Accounting Standards
UAE corporate tax requires IFRS-compliant financial statements as the basis for computing taxable income. Free zone companies must maintain separate accounting for qualifying and non-qualifying income and expenses. This segregation must be reflected in the books, not reconstructed at filing time.
Annual Tax Return
The corporate tax return must be filed within 9 months of the end of the relevant tax period. For a December 31 year-end, the filing and payment deadline is September 30 of the following year. There is no extension mechanism. Missing the deadline triggers penalties.
Transfer Pricing Documentation
Related party transactions must be conducted at arm's length. Companies with related party transactions above certain thresholds must prepare and maintain a Master File and Local File in accordance with OECD guidelines. Country-by-Country Reporting applies to multinational groups with consolidated revenue above AED 3.15 billion.
Penalties: What Changed in April 2026
The FTA reformed its penalty framework in April 2026. The new structure rewards proactive disclosure and simplifies the tariff for errors discovered at audit.
Updated Penalty Schedule
| Violation | Penalty (post-April 2026 reform) |
|---|---|
| Late registration | AED 10,000 (unchanged) |
| Late tax return filing | AED 1,000 first month; AED 2,000/month thereafter (max AED 10,000) |
| Late tax payment | 4% on due date; 14% per annum + daily penalties |
| Failure to maintain records | AED 10,000 to AED 50,000 |
| Errors discovered by FTA at audit | 15% flat penalty on unpaid tax (replaces previous tiered structure) |
| Voluntary disclosure before audit notice | Substantially reduced penalty (lower tier) |
| Voluntary disclosure after audit notice | 15% flat + 1% per month on the tax difference |
The Key Takeaway from the Reform
The April 2026 reform explicitly rewards businesses that come forward proactively. If you have identified an error in a previous return, disclosing it before any FTA contact is made will result in significantly lower penalties than if the same error is found during an audit. The window to use this to your advantage is now.
Key Dates and Compliance Calendar
| Deadline | Event |
|---|---|
| 31 December 2026 | Last period eligible for Small Business Relief election |
| 30 September 2026 | CT return + payment deadline for December 31, 2025 year-end |
| 30 September 2027 | CT return + payment deadline for December 31, 2026 year-end |
| 15 months after period end | DMTT (Pillar Two) return deadline for in-scope groups |
| 28 days after quarter end | VAT return + payment deadline |
Interaction with VAT
UAE VAT and corporate tax are separate obligations with different registration thresholds, return periods, and payment deadlines.
UAE VAT was introduced in January 2018 at a rate of 5% on most goods and services. VAT registration is mandatory if taxable turnover exceeds AED 375,000 per year. Voluntary registration is available above AED 187,500. VAT returns are filed quarterly for most businesses.
Both VAT and corporate tax registrations are managed through EmaraTax, but with separate registration numbers (VAT TRN and CT TRN). Both sets of obligations and penalties run independently. Poor compliance in one area does not affect your standing in the other — but both can accumulate simultaneously.
Strategic Planning: Six Rules
Rule 1: Document substance before the audit arrives. Free zone qualifying status depends on demonstrable substance. Maintain records of your physical office, employees, management meetings conducted in the UAE, and your decision-making process. These records are the difference between a clean qualification and a disqualification.
Rule 2: Use separate entities for qualifying and non-qualifying activities. If your group has both international business and UAE mainland business, keep these in separate entities. Running them through the same free zone company risks triggering the tainted income rule on all your income.
Rule 3: Document transfer pricing from day one. Service agreements, management fees, intercompany loans, and IP licenses all require arm's length documentation. Preparing this retrospectively is significantly more expensive and less defensible than maintaining it as you go.
Rule 4: Plan for life after Small Business Relief. If you are currently using Small Business Relief, the window closes December 31, 2026. Use 2026 to build the accounting infrastructure, process documentation, and professional relationships you will need for full compliance from January 1, 2027.
Rule 5: If in scope for Pillar Two, start the ETR assessment now. The DMTT requires a jurisdiction-level effective tax rate calculation. This is technically complex and cannot be built at the last minute. Groups within scope should have their GloBE assessment underway and their EmaraTax DMTT registration completed.
Rule 6: If you have an error, disclose it now. The April 2026 reform created a clear financial incentive for proactive disclosure. Businesses that have identified gaps in previous filings should use the voluntary disclosure mechanism before any FTA contact is initiated.
Case Studies
Case A: DMCC Commodity Trading Company
A commodity trading company registered in DMCC generates AED 5 million in annual revenue. 80% is from international commodity trading (qualifying activity). 20% is from sales to UAE mainland customers (non-qualifying).
The mainland income represents 20% of total revenue, well above the 5% tainted income threshold. The company loses QFZP status. All AED 5 million is subject to corporate tax. After the AED 375,000 threshold, approximately AED 4.6 million is taxed at 9%, resulting in a corporate tax liability of approximately AED 415,000.
The solution: serve UAE mainland clients through a separate mainland entity. Keep the DMCC company's revenue 100% international.
Case B: Mainland Consulting LLC
A mainland LLC provides consulting services to UAE clients. Revenue is AED 2 million. The company is subject to corporate tax as a mainland entity but elects Small Business Relief. Tax payable: zero.
From January 1, 2027, the same company will owe 9% on profits above AED 375,000 if the relief is not extended. The company is using 2026 to implement IFRS-compliant accounting and engage a tax advisor for its first full-regime return.
Case C: Dubai Silicon Oasis Technology Startup
A technology startup in DSO generates AED 800,000 in revenue entirely from international software licensing. Revenue is below AED 3 million. The company qualifies for both QFZP status and Small Business Relief.
Rather than electing Small Business Relief, the company registers as a normal corporate taxpayer and files a zero-tax return. The reason: building a compliance history from inception simplifies banking relationships, removes uncertainty if revenue grows above the threshold mid-year, and avoids a compliance step-change later.
Case D: Large Group Subsidiary (Pillar Two)
A constituent entity of a EUR 5 billion consolidated group operates as a DIFC holding company. Pre-DMTT, the entity paid zero corporate tax on dividend income (exempt). Under the DMTT rules effective January 1, 2025, the group's UAE ETR must be assessed. If the effective rate falls below 15%, a top-up tax is owed.
The group completes a GloBE effective tax rate assessment, registers on EmaraTax for DMTT, and files a Top-up Tax Return within 15 months of the period end. The CFO engages a specialist adviser for the ETR computation.

Conclusion: The Baseline Has Changed
The UAE corporate tax framework is not punitive. For qualifying free zone businesses with genuine substance, the effective rate remains zero. For mainland businesses, 9% applies only above AED 375,000. Small Business Relief remains available through December 31, 2026.
What has changed is the baseline expectation. The FTA is auditing. Penalties apply. And from January 1, 2027, every business that has relied on Small Business Relief enters the full compliance regime.
The businesses that navigate this environment well treat tax compliance as infrastructure, not administration. They build the systems, maintain the documentation, and engage professional support before they need it, not after.
