UAE Corporate Tax in 2026: The 9% Rule for Founders
How UAE Corporate Tax works in 2026: 0% on first AED 375k, 9% above, QFZP free zone treatment, registration deadlines, and the 9-month CT return cycle.
Quick Answer
UAE Corporate Tax applies 0% on the first AED 375,000 of profit and 9% above. Qualifying Free Zone Persons (QFZP) can retain 0% on Qualifying Income from Free Zone or non-UAE customers. Registration is mandatory for all UAE companies via EmaraTax. Annual CT return due within 9 months of financial year-end. Multinational groups with €750m+ revenue face a 15% Domestic Minimum Top-up Tax under Pillar Two from 2025.
The UAE introduced Corporate Tax in 2023 — ending decades of zero-tax operating for many businesses. The rate is still one of the lowest globally, but the rules around Free Zones, registration deadlines, and Pillar Two top-up taxes are significantly more complex than the headline "9%" suggests.
This guide covers what UAE founders actually need to know in 2026.
The headline rates
| Income band | Rate |
|---|---|
| First AED 375,000 of taxable income | 0% |
| Above AED 375,000 | 9% |
| QFZP Qualifying Income | 0% |
| Pillar Two top-up (groups with €750m+ revenue) | 15% effective minimum |
For most owner-managed UAE businesses, only the 0% / 9% rates matter. The QFZP regime makes Free Zones particularly attractive for B2B and export-focused businesses.
Worked example — mainland LLC
Acme Trading LLC (Dubai mainland) earns AED 1,200,000 taxable income for the year ended 31 December 2025.
| Item | Amount |
|---|---|
| Taxable income | AED 1,200,000 |
| 0% on first AED 375,000 | AED 0 |
| 9% on remaining AED 825,000 | AED 74,250 |
| Corporate Tax due | AED 74,250 |
| Effective rate | 6.2% |
Compared to most G20 economies (UK 25%, Australia 25–30%, US ~21–28% federal+state), even after the introduction of CT, the UAE remains highly competitive.
QFZP — the Free Zone advantage
Qualifying Free Zone Person status lets a Free Zone entity retain the 0% rate on Qualifying Income. This is the structure most attractive to founder-led businesses — but the tests are strict.
To qualify:
- Registered in a Free Zone (DMCC, IFZA, ADGM, DIFC, etc.)
- Adequate substance — people, assets, expenditure in the Free Zone
- Audited financial statements
- Transfer pricing compliance for related-party transactions
- De minimis test passed — non-qualifying revenue ≤5% of total or AED 5m, whichever is lower
Qualifying Income (taxed at 0%):
- Income from transactions with other Free Zone Persons (in qualifying activities)
- Income from "qualifying activities" with non-UAE customers (manufacturing, trading commodities, holding shares, IP, etc.)
Non-qualifying income (taxed at 9%):
- Income from mainland UAE customers (other than treated as Domestic PE or specific allowed activities)
- Income from "excluded activities" (e.g., banking, insurance, headquarters services, investment management with retail clients)
Get the structure wrong and a single mainland transaction can disqualify QFZP for a full 5 years.
Registration — mandatory and deadline-sensitive
All UAE businesses must register for Corporate Tax via the FTA's EmaraTax portal — even if profits are below AED 375,000 or fall under QFZP 0%.
Registration deadlines depend on the date the trade license was issued. The FTA publishes deadlines by month — for example, licenses issued in January–February: register by 31 May 2024; March–April: by 30 June; etc. New licenses issued from 1 March 2024: register within 3 months.
Failure to register on time: AED 10,000 administrative fine.
Annual CT return cycle
Once registered:
| Item | Date |
|---|---|
| Financial year-end | Calendar year by default; may elect non-calendar |
| CT return due | 9 months after year-end |
| Tax payment due | Same date as return |
Example: a 31 December 2025 year-end has the CT return due 30 September 2026.
The return is filed via EmaraTax with:
- Profit and loss reconciliation (accounting profit → taxable income)
- 0% / 9% / QFZP rate application
- Transfer pricing disclosures for related-party transactions
- Pillar Two top-up calculation (for groups with €750m+ revenue)
Audited financial statements may be required (mandatory for QFZPs and large entities).
Pillar Two top-up — for large multinationals only
From 1 January 2025, the UAE applies a Domestic Minimum Top-up Tax (DMTT) of 15% effective rate to multinational groups with consolidated revenue ≥ €750 million in at least 2 of the prior 4 years. This implements OECD Pillar Two.
For owner-managed UAE businesses well below €750m, this is irrelevant. For UAE subsidiaries of large multinationals, the DMTT can effectively raise the UAE rate from 9% to 15% — eliminating the prior tax advantage.
Common mistakes
- Assuming Free Zone = 0%: only QFZPs qualify, and only on Qualifying Income
- Mainland customer transactions that disqualify QFZP for years
- Late registration — even nil-tax-liability companies must register
- Missing transfer pricing documentation for related-party transactions (UAE has full TP rules now)
- Filing the return late — within 9 months means strictly 9 months, not "early in the next year"
- Forgetting that VAT registration is separate (mandatory at AED 375k turnover, regardless of CT)
