For decades, the UAE was known as a zero-tax jurisdiction. That changed on 1 June 2023, when Federal Decree-Law No. 47 of 2022 brought a 9% corporate tax into force — one of the lowest rates among developed economies, but a genuine compliance obligation all the same. Many finance teams were caught off-guard by how quickly registration deadlines arrived. If you're managing UAE tax obligations for a UAE entity, you need to understand the rates, the exemptions, the filing calendar, and the penalties before they catch you out.
This guide covers every layer of UAE corporate tax: who pays, what rate applies, how free zones fit in, what you can deduct, when returns are due, and what happens if you miss a deadline.
Key Takeaways- UAE corporate tax is 9% on taxable income above AED 375,000, with a 0% band below that threshold (UAE Ministry of Finance, 2022).- Qualifying Free Zone Persons pay 0% on qualifying income — but must maintain adequate substance and stay below the de minimis non-qualifying income cap.- All taxable persons must register with the FTA, even if they owe zero tax; late registration carries an AED 10,000 penalty.- Multinationals with global revenue above €750 million face a 15% Domestic Minimum Top-up Tax from 1 January 2025.- Small businesses with revenue of AED 3 million or less can elect 0% relief until at least 31 December 2026.

What is UAE corporate tax and who must pay it?
In 2022, the UAE enacted Federal Decree-Law No. 47 of 2022, introducing a corporate tax effective for financial years starting on or after 1 June 2023 (UAE Ministry of Finance, "Corporate Tax", 2022). The tax applies to the net income of businesses — not gross revenue — and covers UAE-incorporated companies, foreign companies with a permanent establishment in the UAE, and individuals conducting business activities under a commercial licence.
So who is actually exempt? A defined set of persons falls outside the corporate tax net entirely. These include UAE federal and emirate government entities, wholly government-owned entities carrying out sovereign activities, qualifying investment funds, qualifying pension and social security funds, and public benefit entities approved by the Cabinet (UAE Ministry of Finance, Federal Decree-Law No. 47 of 2022). If your business doesn't fall into one of those categories, corporate tax almost certainly applies.
Free zone businesses aren't exempt by default — they're subject to the regime, but a separate set of qualifying conditions can bring their rate down to 0% on eligible income. More on that in the free zones section below.
One point that surprises many finance managers: branches of foreign companies operating in the UAE are also within scope. So is the UAE-source income of certain non-residents without a formal UAE entity. The net is wider than many expected when the law was first announced.

What are the UAE corporate tax rates in 2026?
The UAE corporate tax structure has three tiers, not two. The widely cited 9% rate applies only above AED 375,000 in taxable income (UAE Ministry of Finance, "Corporate Tax", 2022). Below that threshold, the rate is 0% — an intentional design choice to protect small and micro businesses from the compliance burden.
Here's how the tiers work in practice. Income up to AED 375,000 attracts 0% tax. Income above AED 375,000 is taxed at 9% — but only on the portion above the threshold, not on the full amount. A business earning AED 1 million pays 9% on AED 625,000, not on AED 1 million.
A third tier exists for multinationals. UAE-based entities that are part of a multinational enterprise group with consolidated global revenue exceeding €750 million (approximately AED 3.15 billion) are subject to a 15% Qualified Domestic Minimum Top-up Tax (QDMTT). This rule took effect for financial years starting 1 January 2025 and aligns the UAE with the OECD Pillar Two global minimum tax framework (UAE Ministry of Finance, "Qualified Domestic Minimum Top-up Tax", 2025).
How competitive is 9%? Consider the global context. According to the OECD's 2025 Corporate Tax Statistics, the OECD average corporate rate sits at 21.5%. The UAE's 9% rate is less than half that average — and lower than Qatar's 10%, Singapore's 17%, the US federal rate of 21%, and the UK's 25% (OECD, "Corporate Tax Statistics 2025", 2025).

How does UAE corporate tax affect free zone businesses?
Free zone companies are subject to UAE corporate tax — full stop. The relevant question is whether a free zone entity qualifies for the 0% rate on its eligible income. In 2023, the FTA confirmed that a Qualifying Free Zone Person (QFZP) pays 0% on qualifying income and 9% on non-qualifying income (UAE Federal Tax Authority, "Free Zone Persons Corporate Tax Guide", 2023).
What makes income "qualifying"? Income from transactions with other free zone businesses, or from activities specifically permitted within a free zone, generally qualifies. Income from UAE mainland customers, certain financial services, and some real estate activities typically doesn't qualify. The distinction matters enormously for businesses that trade across both free zone and mainland markets.
There's also a de minimis rule. A QFZP can earn some non-qualifying income and still retain its QFZP status, provided that non-qualifying income doesn't exceed 5% of total revenue or AED 5 million — whichever is lower (UAE Federal Tax Authority, 2023). Breach that threshold and the entity loses its QFZP status for that tax period, with 9% applying to all income.
Substance requirements apply too. A QFZP must maintain adequate economic substance in the free zone: real employees, genuine management, and actual operations. A post-box entity with no real activity in the free zone won't qualify.
In practice, many free zone businesses underestimate how quickly non-qualifying income accumulates. A single large contract with a mainland client can push a company over the de minimis threshold, triggering 9% across all income for that year. Quarterly tracking of qualifying versus non-qualifying revenue ratios is worth building into your management accounts.

How do you register for UAE corporate tax?
Registration is mandatory for all taxable persons — not just those expecting to owe tax. In 2023, Cabinet Decision No. 75 confirmed that every business within scope must register with the Federal Tax Authority, even if its taxable income falls entirely within the 0% band (UAE Federal Tax Authority, "Corporate Tax", 2023). The penalty for late registration is AED 10,000 per occurrence.
New businesses must register within three months of incorporation. Existing businesses were given a staggered deadline by entity type when the regime launched — most deadlines have now passed, meaning unregistered businesses are already non-compliant.
Registration is completed through the FTA's EmaraTax portal. You'll need your trade licence, Emirates ID or passport details for authorised signatories, financial year start and end dates, and your business activity description. The process is fully digital and takes most businesses less than an hour to complete.
Do you need a tax agent to register? No. Any authorised signatory of the business can complete registration. A tax agent is only required if you want professional representation during audits or correspondence with the FTA.
For a step-by-step walkthrough, see our UAE corporate tax registration guide.
One practical note: your corporate tax registration number is separate from your VAT registration number (TRN). Keep them distinct in your accounting records — the FTA uses different identifiers for each tax type.

Allowable deductions under UAE corporate tax
The UAE corporate tax law follows a broad deductibility principle: expenses incurred wholly and exclusively for business purposes are deductible, unless specifically disallowed (UAE Ministry of Finance, "Corporate Tax", 2022). Standard operating costs — salaries, rent, utilities, professional fees, depreciation — are generally deductible in full.
Three areas have specific limitations worth knowing.
Interest expense. Net interest expenditure is deductible up to 30% of Adjusted EBITDA for the tax period, or AED 12 million — whichever is higher (UAE Ministry of Finance, "Federal Decree-Law No. 47 of 2022," Article 30). This rule targets highly leveraged structures and aligns the UAE with OECD BEPS Action 4 recommendations.
Related-party transactions. Transfer pricing rules require that transactions between connected persons be priced at arm's length, following OECD guidelines (UAE Ministry of Finance, 2022). If the FTA determines a related-party transaction wasn't conducted at arm's length, it can adjust the taxable income upward.
Tax losses. Losses from a tax period can be carried forward indefinitely. However, they can only offset up to 75% of taxable income in any given future period (UAE Ministry of Finance, "Federal Decree-Law No. 47 of 2022," Article 37). A business with AED 1 million in taxable income and AED 2 million in accumulated losses can offset AED 750,000 in that year — not the full AED 1 million.
Dividends received from UAE resident companies are generally exempt under the participation exemption. Capital gains on qualifying ownership interests in subsidiaries are also exempt, under conditions set out in the law. So if you're holding a UAE subsidiary and planning a disposal, the gain may well be tax-free — but the conditions are specific and worth checking with a tax adviser.

When must UAE businesses file their corporate tax return?
The UAE corporate tax filing deadline is nine months after the end of the relevant tax period (UAE Ministry of Finance, "Corporate Tax", 2022). For a business with a calendar-year financial year (January to December), the first corporate tax period ran from 1 January 2024 to 31 December 2024, with the return due by 30 September 2025.
Filing is done through the FTA's EmaraTax portal. The return must include the computation of taxable income, details of any elections made (such as Small Business Relief), and payment of any tax due. Tax is payable at the same time as the return — there's no separate payment deadline.
What if your financial year doesn't run January to December? The nine-month rule still applies from your year-end. A business with a 31 March year-end files by 31 December. A business with a 30 June year-end files by 31 March the following year.
Tax groups — groups where a parent owns at least 95% of its subsidiaries — can file a single consolidated return. The parent entity files on behalf of the group, which simplifies administration considerably for multi-entity UAE structures.
Small Business Relief must be elected on the return for each period it applies. Don't assume it carries forward automatically — it doesn't.

What penalties apply for corporate tax non-compliance?
The UAE corporate tax penalty regime is designed to compel registration and filing — not to generate revenue from minor errors. The headline penalty for late registration is a flat AED 10,000, under Cabinet Decision No. 75 of 2023 (UAE Federal Tax Authority, "Corporate Tax", 2023). This applies regardless of whether you owe any tax.
Late filing and late payment carry separate penalties. The FTA can assess penalties for late submission of returns, late payment of tax, and errors in returns that understate taxable income. The penalty structure mirrors the approach used for VAT non-compliance, with both fixed and percentage-based penalties depending on the nature of the breach.
What's the practical risk? A business that misses its registration deadline, then misses its filing deadline, and underpays tax could accumulate multiple penalty categories simultaneously. The AED 10,000 late registration penalty alone has caught many smaller businesses that assumed registration was optional if they owed zero tax. It isn't.
The same risk-based framework applies to corporate tax as to VAT. The UAE VAT audit preparation guide covers the documentation standards the FTA expects across both regimes.
The FTA conducts corporate tax audits on a risk-based basis. Businesses with high related-party transactions, inconsistent margins, or unusual loss positions are more likely to be selected. Maintaining clean, well-documented accounting records — and being able to demonstrate arm's length pricing for related-party transactions — is the most effective audit protection available.

Conclusion
UAE corporate tax is straightforward in structure — a 0% band below AED 375,000, a 9% rate above it, and a set of well-defined exemptions and reliefs. But the compliance details matter. Registration is mandatory for everyone in scope. Filing deadlines run nine months from year-end. Free zone status doesn't automatically mean a 0% rate. And multinational groups above €750 million face a separate 15% minimum tax from 2025.
The businesses getting into trouble aren't usually those with complex structures. They're the ones that registered late, missed an election, or assumed a free zone licence provided a blanket exemption. Don't let administrative slip-ups create penalties that proper calendar management would have prevented.
Your next step: confirm your registration status in EmaraTax today, map your financial year to the filing deadline, and review your free zone income split if you operate across zones and the UAE mainland.
For a deeper look at how UAE tax compliance is evolving, UAE e-invoicing requirements mandatory from 2027 will affect every VAT-registered business. Now is the time to align your invoicing systems with what the FTA will expect.
