For decades, the UAE was known as a tax-free business hub. That changed with the introduction of a federal Corporate Tax on business profits, effective for financial years beginning on or after 1 June 2023. For most businesses in the country, this is the first time profit has been taxed at all — and getting the basics right, from registration through to the first return, is now part of running a compliant company. This guide explains how the regime works in plain language.
Who does UAE Corporate Tax apply to?
Corporate Tax applies broadly to businesses operating in the UAE. The law works through the concept of a "taxable person", which falls into two main groups:
- Resident persons — UAE-incorporated companies and other juridical persons (including free zone entities), and individuals who conduct business or business activity in the UAE above the relevant threshold.
- Non-resident persons — foreign companies with a permanent establishment in the UAE, or that earn certain UAE-sourced income.
Employment income, personal investment income, and real estate income earned by individuals in their personal capacity are generally outside the scope. Most government entities, certain qualifying public-benefit entities, and qualifying investment funds can be exempt, subject to conditions. If you operate through a company or a licensed business, you should assume you are in scope until confirmed otherwise.
The rates and the AED 375,000 threshold
The headline structure is deliberately simple and competitive:
| Taxable income | Corporate Tax rate |
|---|---|
| Up to AED 375,000 | 0% |
| Above AED 375,000 | 9% |
| Qualifying income of a Qualifying Free Zone Person | 0% |
The AED 375,000 threshold means small businesses and start-ups pay no Corporate Tax on their first slice of profit, with the 9% rate applying only to profit above it. A separate set of rules under the OECD's global minimum tax framework can impose a higher effective rate on very large multinational groups, but that affects only a small number of businesses.
Free zones and the Qualifying Free Zone Person
Free zones remain central to the UAE's economy, and the regime preserves a 0% rate for them — but on conditions. A free zone company is within the Corporate Tax system and must register and file like any other taxable person. It can apply 0% only to its "qualifying income", and only if it is a Qualifying Free Zone Person (QFZP). To be a QFZP, an entity must:
- Maintain adequate substance in the UAE — real people, premises, and activity, not just a licence.
- Derive qualifying income from qualifying activities, and not elect to be taxed at the standard rate.
- Stay within the de minimis limit on non-qualifying revenue.
- Prepare audited financial statements.
- Comply with transfer pricing rules and documentation.
Income that is not qualifying — or a breach of the conditions — is taxed at 9%, and a breach can cost the QFZP status for several years. Because the definitions of qualifying activities and income are detailed and have been refined by Cabinet decision, free zone businesses should have their position assessed rather than assume the 0% rate applies automatically.

Corporate Tax is charged on taxable income, which begins with the accounting profit shown in financial statements prepared under IFRS (or IFRS for SMEs). That accounting profit is then adjusted for the items the law treats differently:
- Add back disallowed or limited expenses — for example, a portion of entertainment costs and interest above the deductibility limit.
- Deduct exempt income — such as qualifying dividends and gains under the participation exemption.
- Apply reliefs — small business relief, transfers within a qualifying group, and business restructuring relief, where elected and available.
- Apply transfer pricing adjustments — so related-party transactions reflect arm's-length pricing.
Because the computation starts from IFRS accounts, accurate, well-kept books are the foundation of correct Corporate Tax. Messy records do not just risk an accounting problem — they directly distort your tax.
Registration and the Tax Registration Number
Registration is mandatory for taxable persons, and it is done through the FTA's EmaraTax portal, which issues a Tax Registration Number. Crucially, free zone companies must register even when they expect to qualify for the 0% rate. The FTA has set registration deadlines based on the month of a company's licence issuance, and missing the applicable deadline can attract an administrative penalty — so confirming and meeting your registration date is the first priority.
Filing the return and paying the tax
Corporate Tax operates on a self-assessment basis with a single annual return. The return must be filed, and any tax paid, within nine months of the end of the relevant tax period (normally your financial year). For example:
| Financial year-end | First tax period | Return & payment due |
|---|---|---|
| 31 December 2024 | 1 Jan – 31 Dec 2024 | 30 September 2025 |
| 31 May 2025 | 1 Jun 2024 – 31 May 2025 | 28 February 2026 |
| 30 June 2025 | 1 Jul 2024 – 30 Jun 2025 | 31 March 2026 |
There are no provisional or advance returns — just one return per period — which makes a timely, accurate year-end close essential. Records supporting the return must be retained for the period the law prescribes (generally seven years).
Small Business Relief
To ease the burden on smaller businesses, Small Business Relief lets a resident taxable person with revenue at or below the prescribed threshold (AED 3 million for the relevant periods) elect to be treated as having no taxable income for that period. The relief reduces both the tax and the compliance effort, but it must be elected, it is time-limited under the current rules, and it interacts with other reliefs — so it is worth checking whether electing is genuinely to your advantage.
What businesses should do now
- Confirm your tax period, registration deadline, and whether you are (or should remain) a Qualifying Free Zone Person.
- Register with the FTA through EmaraTax and obtain your Tax Registration Number.
- Get your bookkeeping onto IFRS-compliant footing, because your return is built from it.
- Review related-party transactions for transfer pricing, and your income streams for exemptions and reliefs.
- Diarise your nine-month filing deadline and prepare the computation well ahead of it.
Corporate Tax is now a permanent feature of doing business in the UAE, and the businesses that treat it as a routine, well-managed obligation will find it straightforward. If you would like a clear view of your position — or want the whole cycle handled for you — talk to our team.

- Registration with the Federal Tax Authority is mandatory for taxable persons — including most free zone companies — whether or not tax is ultimately payable.
- A Qualifying Free Zone Person can keep a 0% rate on qualifying income, but only by meeting strict substance, activity, de minimis, and transfer pricing conditions.
- Taxable income starts from IFRS accounting profit, then adjusts for disallowed expenses, exempt income, and reliefs — so clean books are essential.
- The return is filed, and tax paid, within nine months of the financial year-end; there is one return per period, with no provisional filings.
- Rates, thresholds, and reliefs are set by law and refined over time — treat figures as the current position and confirm before acting.
