UAE Corporate Tax (CT) became law in June 2023 under Federal Decree-Law No. 47 of 2022. By 2026 the regime is no longer new — registration windows have closed, the first returns have been filed, the FTA has issued its first round of clarifications, and the patterns of what works and what gets penalised are visible. This guide is the FCCA-led summary of what a founder actually needs to know to operate inside the UAE Corporate Tax system in 2026, organised around the questions we get most often in the Consorata practice.
Who is a Taxable Person
The CT Law applies to two classes of person.
A Resident Juridical Person is any entity incorporated in the UAE, including free-zone entities. The label is the same whether the company sits in DMCC, IFZA, ADGM, or on the mainland under DED — what differs is the rate structure available, not the obligation to register.
A Non-Resident Juridical Person is a foreign entity with a UAE Permanent Establishment (PE), a nexus established by Cabinet Decision 56 of 2023, or UAE-sourced income subject to withholding. Non-residents register for CT in respect of their UAE PE only — the foreign parent itself is not a UAE Taxable Person.
Natural persons (sole establishments, freelance permits, individuals trading in their own name) become Taxable Persons only where their Turnover from business or business activity in the UAE exceeds AED 1 million in a Gregorian calendar year (Cabinet Decision 49 of 2023). Personal investment income, real estate income, and salaries paid under an employment relationship are not in scope.
The rate structure
The headline rates are simple. The implementation is not.
- 0% on the first AED 375,000 of Taxable Income per tax period
- 9% above AED 375,000
- 0% on Qualifying Income for a Qualifying Free Zone Person (QFZP) — 9% on the rest, with no AED 375k threshold
- 15% effective rate under the Domestic Minimum Top-up Tax (DMTT) for in-scope Multinational Enterprise (MNE) Groups, financial years starting on or after 1 January 2025 (Cabinet Decision 142 of 2024)
The AED 375k threshold is per tax period and per Taxable Person — not per group. Splitting a single business across two entities does not double the threshold; the General Anti-Abuse Rule under Article 50 of the CT Law specifically catches that structure.
Qualifying Free Zone Person — the 0% that catches founders
The Free Zone 0% is the most asked-about and most misunderstood feature of the regime. It is not “free zones don’t pay CT”. A QFZP must pass five tests simultaneously every tax period (Article 18 of the CT Law, refined by Cabinet Decision 55 of 2023 and Cabinet Decision 100 of 2023):
- Adequate substance in the Free Zone — core income-generating activities, employees, operating expenditures, assets located in the zone proportionate to the Qualifying Income generated
- Qualifying Income — transactions with other Free Zone Persons (where they are the beneficial recipient) plus a defined list of Qualifying Activities (manufacturing, processing, holding of shares and other securities, ownership / management of ships, fund management, wealth and investment management, headquarter services, treasury and financing services to related parties, financing and leasing of aircraft, distribution of goods or materials from a Designated Zone, logistics services, and any ancillary activity)
- No election to be subject to standard 9% CT (an irrevocable election; once made you cannot revert to QFZP status)
- Arm’s-length pricing for related-party transactions plus full transfer-pricing documentation per Cabinet Decision 97 of 2023
- De minimis — non-Qualifying Revenue cannot exceed the lower of AED 5 million or 5% of total revenue in the tax period
Fail any one and QFZP status is lost for that tax period and the four subsequent periods — five years, not one. The de minimis test in particular catches founders who casually invoice a UAE mainland customer thinking it’s “small”. It is small until total non-qualifying revenue crosses 5% of total or AED 5M, then it is fatal.
Mainland-sourced revenue from non-qualifying activities is always taxed at 9% — even for a fully compliant QFZP. The 0% applies to Qualifying Income only.
Small Business Relief — the AED 3M election
Ministerial Decision No. 73 of 2023 introduced Small Business Relief (SBR) as a transitional simplification. A Resident Person electing SBR is treated as having zero Taxable Income for the period — no CT, no normal computation.
Eligibility requires:
- Revenue ≤ AED 3 million in the current AND every preceding tax period since CT came into force
- Not a QFZP, not a Multinational Enterprise Group within Pillar Two scope (consolidated group revenue ≥ EUR 750 million)
- Tax periods ending on or before 31 December 2026 (the relief is currently scheduled to end here — likely to be reviewed before then)
Two structural points founders miss. First, the AED 3M threshold is a hard cliff, not a tapered relief — AED 3,000,001 of revenue moves you to standard CT in full for that period. Second, tax losses cannot be carried forward from an SBR period — electing SBR in a high-investment year (where you’d otherwise generate a useful loss) trades a permanent loss-utilisation right for a one-period zero. We model the trade-off explicitly on engagement.
Registration — what changed in 2024 and 2025
FTA Decision No. 3 of 2024 set staged registration deadlines for entities existing on 1 March 2024, indexed by the month of trade-licence issuance — most fell between May and December 2024. The non-compliance penalty is AED 10,000 per Cabinet Decision 75 of 2023, applied per Taxable Person.
For entities incorporated after 1 March 2024: register within 3 months of incorporation. The clock starts at the trade-licence-issued date, not the operational launch date — a frequent source of late penalties for founders who delay registration until they “have something to file”.
If you missed your deadline: register today, pay the AED 10,000, file as normal. There is no benefit to waiting; further months do not reduce the penalty (which is fixed) but do increase the risk of a related Voluntary Disclosure obligation if revenue has been earned in the unregistered period.
The first return — what we see in practice
The first CT return is due 9 months after the end of the tax period. For a calendar-year filer the 2024 return ran to 30 September 2025; the 2025 return is due 30 September 2026.
Three first-year transitions matter and are routinely mishandled:
Opening-balance adjustments. Pre-CT-effective fixed assets, intangibles, investment-property reclassifications, and deferred-tax setup all need to be locked at the start of the first tax period. Ministerial Decision 120 of 2023 (the transitional rules) gives one-time elections — they cannot be re-made later. Getting the opening balance wrong puts every subsequent year’s return on a wrong foundation.
Transitional rules for goodwill, intangibles, and immovable property (Ministerial Decision 120 of 2023). Pre-CT goodwill and intangibles can be carried at fair value as of the first day of the first tax period, with depreciation deductible against future gains. Pre-owned UAE immovable property held on capital account can be excluded from gain on disposal up to the pre-CT fair value. These elections need to be made on the first return — late elections are not accepted.
Tax loss carry-forward. Pre-CT losses are not carried forward into CT periods. Losses generated in CT periods carry forward indefinitely (subject to the 75%-of-current-Taxable-Income utilisation cap and the no-substantial-change-in-ownership rule under Article 39).
What’s coming in 2026
The biggest 2026 change is Pillar Two. The UAE adopted a Domestic Minimum Top-up Tax via Cabinet Decision 142 of 2024 and Federal Decree-Law 60 of 2023. For Multinational Enterprise Groups with consolidated group revenue ≥ EUR 750 million in at least two of the four preceding financial years, the effective UAE tax rate is brought to 15% for financial years starting on or after 1 January 2025 — first DMTT returns are due in 2026.
The DMTT is computed on GloBE-rules-aligned Pillar-Two income and applies on a jurisdictional basis. A 9% headline rate plus available exemptions and deductions can produce a sub-15% effective rate per jurisdiction; the DMTT picks up the difference. Smaller groups are not in scope but should track whether group revenue growth pushes them across the EUR 750M threshold for two of four preceding years — entry into Pillar Two scope is automatic, not elective.
Common mistakes we see
The most expensive mistakes in our 2024-2026 engagements have been about timing and election irrevocability, not the headline rate:
- Treating QFZP as default for every free-zone entity — operating on the assumption that the 0% applies and only running the five-test analysis at year-end. By then it’s too late to fix substance gaps or restructure transactions.
- Missing the 3-month new-entity registration window — the AED 10,000 penalty has been issued at scale through 2025.
- Electing standard CT instead of QFZP thinking it simplifies — the election is irrevocable. We have engagements where the election has cost six-figure annual CT that would have been 0%.
- Late opening-balance work — reverse-engineering the first day of CT in month 18 of the tax period, when the audit-firm consult is due. Always set the opening balance at the start.
- Small Business Relief in an investment year — electing SBR and burning the loss-carry-forward right when the loss would have offset future Taxable Income.
The CT regime rewards the same discipline that audit-readiness has always rewarded: clean books from day one, decisions documented, elections made on time. The penalties for getting it wrong are not catastrophic in any single instance, but they compound across tax periods and reduce the elections available later.
