Corporate Tax Liabilities in the UAE: What Businesses Need to Know

Corporate tax liabilities in the UAE are more nuanced than the headline 9% suggests. Introduced for financial years starting on or after 1 June 2023, corporate tax now reaches the great majority of businesses — but who is liable, on what, and after which exemptions and reliefs, takes some unpacking. This guide explains how to understand your corporate tax liabilities: who is a taxable person, how the liability is calculated, what is exempt, how free zones are treated, the reliefs available, and the registration, filing and penalty rules. Rates and core rules are stated as they stand; penalty amounts and a few date-sensitive items are flagged [VERIFY]. This is general information, not tax advice.

What are corporate tax liabilities in the UAE?

A corporate tax liability is the tax a taxable person owes on its taxable income for a tax period. In the UAE that means 0% on the first AED 375,000 of taxable income and 9% on the rest — so the liability is a function of how much taxable income a business has, after all adjustments.

Crucially, the liability is built on adjusted accounting profit, not turnover or cash received. You begin with the profit in the financial statements and apply the corporate tax rules to reach taxable income, then apply the rate. Even a business with a nil liability — because it is below the threshold, in a free zone, or using a relief — usually still has to register and file, so “no tax” is not the same as “no obligations.”

Who is liable for corporate tax in the UAE?

Corporate tax liability falls on taxable persons, both resident and non-resident. The category a business falls into determines what it is taxed on.

The line for individuals is the key one: running a business above AED 1 million in annual turnover brings you into scope on that business income, but employment and private investment returns never do. This distinction matters in practice, because many owners assume any UAE income is now taxed, when only genuine business activity above the turnover threshold is.

What is the corporate tax rate, and how is the liability calculated?

The corporate tax rate is 0% up to AED 375,000 of taxable income and 9% above it, applied to adjusted accounting profit. A separate 15% top-up can apply to very large multinational groups under the global minimum tax [VERIFY the scope and effective date], but the 9% rate is what most businesses deal with.

What income is taxable, and what is exempt?

Most business income is taxable, but the corporate tax law exempts specific income to avoid double taxation. The most important exemptions relieve income that has typically already been taxed elsewhere.

Key exempt income includes dividends and profit distributions from UAE companies, and dividends and capital gains from a qualifying participation under the participation exemption. A taxable person may also elect to exempt the profits of a foreign permanent establishment. Everything else — trading profits, service income, most other gains — forms part of taxable income after the usual deductions for expenses incurred wholly and exclusively for the business, subject to limits such as the interest-deduction and entertainment rules. Distinguishing exempt income from taxable income early is what prevents over-declaring profit and paying more tax than the law requires.

Which persons are exempt from corporate tax?

Certain persons, not just certain income, are exempt from corporate tax — generally on public-interest or economic grounds, and usually subject to conditions and, in some cases, FTA approval.

These include government and qualifying government-controlled entities, businesses engaged in the extraction of natural resources and qualifying non-extractive natural resource businesses (taxed instead at the Emirate level), qualifying public benefit entities, and qualifying investment funds and pension or social security funds that meet the criteria. Exempt status is not automatic for most of these — the conditions have to be met and maintained, and many still have registration or reporting duties.

How does corporate tax apply to free zone companies?

Free zone companies are within corporate tax — they are taxable persons and must register and file — but a Qualifying Free Zone Person (QFZP) can access a 0% rate on its qualifying income. The 0% is a conditional benefit, not a blanket exemption.

To be a QFZP and keep the 0% rate, a business must maintain adequate substance in the free zone, earn qualifying income from qualifying activities, stay within the de minimis limits for non-qualifying revenue, prepare audited financial statements, and meet transfer-pricing requirements. Income that falls outside qualifying income is taxed at 9%. So a free zone address does not, by itself, remove a corporate tax liability — the conditions do the work. In practice, a free zone business should test each stream of income against the qualifying-income rules rather than assuming the whole company benefits from the 0% rate.

What reliefs can reduce a corporate tax liability?

Several reliefs can reduce or defer a corporate tax liability, provided the conditions and any elections are met. Used correctly, they are the main lever for managing the tax legitimately.

Reliefs such as the loss carry-forward and group provisions are covered further in our guide to group loss transfers. Most reliefs require an election and supporting records, so they need to be planned, not claimed as an afterthought. Our Small Business Relief service can confirm whether you qualify.

What are the registration and filing obligations?

Every taxable person must register for corporate tax and file a return — there is no turnover threshold that removes the registration duty, and free zone, 0% and Small Business Relief businesses are all included. The core sequence:

1. Register for corporate tax and obtain your registration number.
2. Keep IFRS-compliant records and retain them for seven years.
3. Compute your taxable income by adjusting accounting profit for the CT rules.
4. Apply reliefs and exemptions you qualify for.
5. File and pay within nine months of your financial year-end.

The nine-month deadline covers both filing and payment, and it applies even where the tax is nil. Our guide to corporate tax filing in the UAE walks through the return itself. If you have not registered yet, our corporate tax registration service handles it from AED 199.

What are the penalties for getting corporate tax wrong?

Corporate tax penalties are set by Cabinet Decision No. 75 of 2023 (as amended), and they are a separate regime from VAT penalties. Missing registration, filing or payment deadlines, or keeping inadequate records, all carry administrative penalties.

Typical triggers include late registration, late or non-filing of the return, late payment of the tax, and failure to keep records — the specific amounts are set by the penalty schedule [VERIFY the current figures]. Because corporate tax penalties (Cabinet Decision No. 75 of 2023) and VAT penalties (Cabinet Decision No. 129 of 2025) are governed separately, the two should never be conflated. As with any tax, a prompt correction is almost always cheaper than waiting for the FTA to raise an assessment. Building the corporate tax deadlines into the finance calendar, and reconciling the tax position each year, is the simplest way to avoid these penalties altogether.

What are common corporate tax liability mistakes?

Most corporate tax liability mistakes come from misreading who or what is taxable, or from confusing corporate tax with turnover or with VAT. The recurring ones:

• Not registering because tax is nil. Free zone, 0% and Small Business Relief businesses must still register and file.
• Taxing turnover, not profit. The liability is built on adjusted accounting profit.
• Assuming a free zone means 0%. Only a QFZP on qualifying income gets 0% [VERIFY conditions].
• Confusing CT and VAT penalties. They sit under different Cabinet Decisions.
• Claiming reliefs without elections or records. Most reliefs require both.
