UAE Corporate Tax: Complete Guide for Mainland, Free Zone & Tax-Free Companies (2024–2025)
The UAE introduced federal corporate tax on 1 June 2023 — a landmark shift for one of the world's most business-friendly jurisdictions. Yet the headline rate of 9% tells only part of the story. Depending on how and where your company is structured, your effective tax rate could be anywhere from 0% to 9%. This guide breaks down exactly what UAE corporate tax means for the three main company types: mainland, free zone, and free zone entities with qualifying tax-free status.
What Is UAE Corporate Tax?
Governed by Federal Decree-Law No. 47 of 2022, UAE corporate tax applies to the net taxable income of businesses operating in the country. The rate structure is deliberately tiered to protect small businesses while applying a meaningful rate to larger operations:
0% on taxable income up to AED 375,000
9% on taxable income above AED 375,000
0% on qualifying income for eligible free zone entities
All businesses — mainland and free zone alike — must register with the Federal Tax Authority (FTA) and file an annual return within nine months of their financial year-end.
Mainland Companies: Standard 9% Rate Applies
A mainland company is licensed by an Emirate-level Department of Economic Development (DED), such as Dubai's Department of Economy and Tourism or Abu Dhabi's DED. Mainland companies can trade freely across the UAE and internationally without geographic restriction.
Corporate tax obligations for mainland companies include:
Registering with the FTA for corporate tax
Preparing IFRS-compliant financial statements
Filing an annual CT return and paying any tax due within nine months of year-end
Maintaining accounting records for at least seven years
Taxable income is calculated from accounting net profit, adjusted for items such as disallowed entertainment expenses (50% disallowance), the interest limitation rule (capped at 30% of EBITDA or AED 12 million), and transfer pricing adjustments on related-party transactions.
Key relief: the Participation Exemption. Dividends and capital gains from a qualifying ownership interest of 5% or more in a subsidiary are fully exempt from UAE CT — eliminating double taxation for holding structures.
Key relief: Small Business Relief. Businesses with revenues of AED 3 million or below can elect to treat their taxable income as zero through 31 December 2026, easing the transition for micro-enterprises.
Free Zone Companies: Subject to CT, but Rate Depends on Structure
The UAE has more than 45 free zones — JAFZA, DIFC, ADGM, DAFZA, and many others. Companies incorporated in a free zone are called Free Zone Persons (FZPs) and are fully subject to UAE corporate tax. The critical question is which rate applies.
A standard free zone company with no special qualifying status pays CT at the same 9% rate as a mainland company (with the same AED 375,000 zero-rate threshold). The main structural advantages — 100% foreign ownership, simplified customs, and streamlined licensing — remain intact, but there is no automatic tax exemption.
The mainland nexus trap. Free zone companies that provide services or sell goods directly to UAE mainland customers generally generate "non-qualifying revenue," which can affect their overall tax position. Understanding which transactions create mainland exposure is one of the most common compliance challenges for free zone businesses operating across both markets.
Free Zone Companies with Tax-Free Status: The Qualifying Free Zone Person (QFZP) Regime
The most tax-advantaged structure in the UAE is the Qualifying Free Zone Person (QFZP). A QFZP pays 0% corporate tax on qualifying income — preserving the tax-free environment that made UAE free zones globally attractive in the first place.
To qualify, a free zone entity must satisfy all of the following:
Adequate substance — genuine physical presence in the free zone, with qualified employees, real premises, and key management decisions made locally
Qualifying income — revenues must arise from qualifying activities (see below)
De minimis non-qualifying revenue — non-qualifying revenue must not exceed the higher of AED 5 million or 5% of total revenue
Audited financial statements — QFZPs must file audited accounts; unaudited financials are not accepted
Transfer pricing compliance — all related-party transactions must be at arm's length
Qualifying activities include: manufacturing, processing, holding of shares and securities, fund and wealth management services, headquarter services to related parties, treasury and financing services, logistics, aircraft financing and leasing, distribution of goods in or from a designated zone, and reinsurance services.
The de minimis cliff edge. If a QFZP's non-qualifying revenue exceeds the threshold in any tax period, the entity loses its 0% status for the entire year — not just the excess portion. All income becomes subject to 9% CT for that period. This makes real-time revenue monitoring a business-critical compliance activity, not just an end-of-year exercise.
How to Use the Calculator Above
Enter your estimated annual net profit into the calculator to see your UAE corporate tax liability based on your company type. For mainland and standard free zone companies, the tool applies the 0%/9% tiered structure automatically. For QFZPs, it models which portion of your revenue qualifies for the 0% rate and flags when your non-qualifying revenue approaches the de minimis threshold.
The calculator is a planning tool. For a definitive tax position, consult a licensed UAE tax advisor registered with the FTA.
UAE Corporate Tax Registration: What Every Business Needs to Know
One of the most common compliance mistakes since the UAE corporate tax regime launched has been late or missed registration. Every business that meets the definition of a taxable person — including free zone companies that expect to pay 0% tax — must register with the Federal Tax Authority. Registration is not optional, and the penalty for failing to register is AED 10,000.
Registration is completed through the FTA's EmaraTax portal. Once registered, the FTA assigns a Tax Registration Number (TRN) for corporate tax purposes, which is separate from a VAT TRN if the business is also VAT-registered. Most businesses established before 1 March 2024 were required to complete registration by 31 May 2024. Businesses incorporated after that date have registration deadlines tied to their incorporation date, so it is worth checking the FTA's published timeline if your company was set up recently.
The registration process requires basic corporate information — trade licence details, financial year-end, ownership structure, and details of any related parties. It is straightforward for most businesses, but companies with complex group structures or cross-border ownership may need additional documentation.
Understanding the UAE Corporate Tax Return
The annual corporate tax return must be filed within nine months of the end of the relevant tax period. For most businesses operating on a calendar year, this means a filing deadline of 30 September of the following year. Tax payment is due at the same time — there is no separate payment deadline.
The return requires disclosure of:
Taxable income and the adjustments made from accounting net profit
Any exemptions claimed, including the Participation Exemption or Small Business Relief
Related-party transactions and transfer pricing information
For QFZPs, a breakdown of qualifying versus non-qualifying income
Unlike many other jurisdictions, the UAE does not currently require provisional or quarterly tax payments. Businesses pay their full liability in a single annual payment alongside the return filing. For companies with large tax bills, this requires careful cash flow planning to avoid a significant year-end outflow.
VAT and Corporate Tax: How the Two Interact
UAE VAT (introduced in January 2018 at 5%) and corporate tax are separate taxes administered by the same authority — the FTA. They have their own registration thresholds, filing cycles, and compliance obligations. But the two taxes interact in ways that catch businesses out.
The most common interaction is around irrecoverable VAT. Where a business incurs VAT that it cannot recover as input tax — for example, on entertainment expenses or exempt supplies — that blocked VAT forms part of the business cost and is therefore a deductible expense for corporate tax purposes. This means businesses with high irrecoverable VAT costs actually get a CT deduction for it, partially offsetting the burden.
Free zone businesses making taxable supplies to UAE customers may have VAT obligations even if their corporate tax position is straightforward. A QFZP that sells goods to a UAE mainland customer would typically need to charge VAT on that sale, even if the CT treatment of the revenue is subject to the de minimis rules. The two taxes do not mirror each other perfectly, and businesses should not assume that a VAT-registered free zone company automatically has no CT exposure, or vice versa.
The FTA cross-references VAT and CT return data. Businesses with significant inconsistencies between revenue reported in VAT returns and income declared in CT returns should expect scrutiny.
