# UAE Corporate Tax in 2026: The 9% Rule for Founders

Last updated: 26 April 2026

UAE Corporate Tax applies 0% on the first AED 375,000 of annual taxable profit and 9% on everything above. Free Zone companies that qualify as a Qualifying Free Zone Person (QFZP) can retain 0% on income from other Free Zone businesses or non-UAE customers. Registration with the FTA via EmaraTax is mandatory for all UAE companies, and the annual CT return is due within 9 months of the financial year-end.

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:

1. **Registered in a Free Zone** (DMCC, IFZA, ADGM, DIFC, etc.)
2. **Adequate substance** — people, assets, expenditure in the Free Zone
3. **Audited financial statements**
4. **Transfer pricing compliance** for related-party transactions
5. **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)
