UAE Corporate Tax went live on 1 June 2023. By May 2026 we are in the third reporting cycle for early adopters and the first cycle for entities with calendar-year accounts that incorporated in 2024. The Federal Tax Authority has been steadily issuing clarifications, and the most useful thing you can do this year is reread the rules with fresh eyes. Here is what 9% actually means in 2026 practice.
The headline rates, in one screen
| Slab | Rate | Applies to |
|---|---|---|
| Taxable income up to AED 375,000 | 0% | All taxable persons |
| Taxable income above AED 375,000 | 9% | All taxable persons |
| Qualifying Income of a QFZP | 0% | Free Zone entities meeting all conditions |
| Non-Qualifying Income of a QFZP | 9% | Free Zone entities, on the bad slice |
| Pillar Two Top-Up | 15% | MNE groups above EUR 750M global revenue |
The AED 375,000 threshold is not pro-rated for short years. A 9-month period gets the full AED 375,000 in 2026. This was a 2025 FTA clarification that lots of accountants still get wrong.
Who pays
Every UAE-incorporated entity, every Free Zone entity, and every UAE permanent establishment of a foreign company. Natural persons (sole traders) are in scope only if their business turnover exceeds AED 1 million in the calendar year and the income is from a business or business activity (not from a job, dividends, or rental).
Who's exempt
- UAE Federal and Emirate governments and their wholly-owned entities.
- Government-controlled entities listed by Cabinet decision.
- Extractive businesses already taxed at the Emirate level (most oil and gas).
- Qualifying Investment Funds, Qualifying Pension Funds, and Social Security Funds (subject to FTA approval).
- Public Benefit Entities listed by the Cabinet.
Note what is not on this exemption list: holding companies, family offices, single-asset SPVs, real estate investment vehicles. They all pay CT unless they meet a specific exemption.
The two real 2026 changes
1. Small Business Relief sunset
Small Business Relief lets a taxable person elect for nil tax if revenue is below AED 3 million in the current and all prior tax periods. The relief was announced to apply for tax periods ending before 31 December 2026. Tax periods starting on or after 1 January 2027 do not get this relief in current law. Founders who relied on SBR for 2024 and 2025 should be modelling their 2027 position now, particularly if they expect to cross the AED 3M revenue mark.
A practical example. A founder with a January-December tax year and AED 2.8M revenue in 2026 elects SBR and pays nil CT. For 2027, the same founder cannot elect SBR, and the AED 375,000 threshold applies normally. Plan the year-end accruals and any deferred income before December 2026, not after.
2. Pillar Two Domestic Minimum Top-Up Tax
For MNE groups with consolidated global revenue above EUR 750 million in at least two of the prior four fiscal years, the UAE applies a 15% Domestic Minimum Top-Up Tax for tax periods starting on or after 1 January 2025. The 9% CT and the 0% QFZP rate stop being relevant for these groups; the effective UAE tax rate is topped up to 15%.
For 99% of our SME and owner-managed clients, this changes nothing. If your group revenue is under EUR 750M, the only thing you need to know is the threshold.
The three rules that catch founders out
Registration deadline
Every taxable person must register for CT. Deadlines were rolled out by month-of-incorporation in 2024. For new incorporations from 2025 onwards, register within 3 months of the date of incorporation. Late registration is AED 10,000 fixed. We see this fine on roughly 1 in 8 new client files.
Tax Group election
UAE entities under 95%+ common ownership can elect to form a Tax Group, filing one CT return with consolidated income. The election has to be made before the start of the tax period in which it applies, with a transitional concession for early periods. A late election cannot be backdated. If you have a parent + UAE subsidiaries structure, decide on the group election before year-end.
Transfer pricing on related-party flows
The arm's-length principle applies to every related-party transaction from day one, regardless of group size. The AED 200 million threshold is for the formal master file / local file requirement. Below that threshold, you still must report related-party transactions on the CT return Schedule and apply arm's-length pricing. A common error: founders who set up a UAE FZE and then invoice it from a personal-name UK consultancy at "whatever number" instead of a defensible market rate.
9% is not high by international standards, but the rules around 9% are dense. Read the FTA's general guide once. Read the clarifications quarterly. Or pay someone to do it for you. The fine for missing a registration deadline is more than a year of accountancy fees.
