Understanding corporate tax liabilities in the UAE

UAE corporate tax liability is 0% on taxable income up to AED 375,000 and 9% above it, under Federal Decree-Law No. 47 of 2022. A Qualifying Free Zone Person can apply 0% to qualifying income. But the headline 9% is the easy part — what you actually owe depends on the reliefs you claim, from Small Business Relief to the participation exemption, and on how cleanly your accounts support them. This guide walks through liability end to end and shows where corporate tax filing and planning reduce the real bill.

Who is liable for corporate tax in the UAE?

Liable persons are resident companies (UAE-incorporated entities, free zone companies included), non-residents with a UAE permanent establishment or nexus, and natural persons running a business whose turnover exceeds AED 1,000,000 in a calendar year. A handful of exempt persons sit outside the charge, though several must still register or notify the FTA.

The UAE was long known for having no corporate income tax. That changed with Federal Decree-Law No. 47 of 2022, which applies to tax periods starting on or after 1 June 2023. The net is wide, but not everyone owes the same — or anything at all. Exempt persons include government entities, qualifying public benefit entities and qualifying investment funds.

One myth worth retiring: that offshore companies are simply “exempt”. They are not blanket-exempt. Liability turns on the taxable-person rules — whether there is UAE-source income, a permanent establishment, or effective management in the UAE — not on the “offshore” label. There is also no UAE personal income tax: a resident individual is only within scope on UAE business income above the AED 1,000,000 turnover line, and never on salary or personal investment income. The practical message for most businesses is that if you operate in the UAE, you are in the regime — the real question is how much.

What corporate tax rate will you actually pay?

Corporate tax is charged in two tiers: 0% on the first AED 375,000 of taxable income, and 9% on the portion above. That two-tier design deliberately protects small businesses and start-ups, so a company with AED 375,000 or less of taxable income pays nothing.

Free zones are where older guidance most needs correcting. There is no “tax holiday for a specified period that can be renewed”. Instead, a Qualifying Free Zone Person (QFZP) can apply 0% to its qualifying income and 9% to any non-qualifying income — provided it meets every QFZP condition each year, including adequate substance and staying within the de minimis limits. A QFZP still registers and files; the 0% is earned and maintained, not automatic, and dealings with the mainland can fall into the 9% bucket.

One more layer affects only the largest players: a Domestic Minimum Top-up Tax (DMTT) brings the effective rate to 15% for multinational groups with global revenue above the OECD Pillar Two threshold. For the overwhelming majority of UAE businesses, though, the numbers that matter are 0% and 9%. You can sanity-check any figure with our UAE corporate tax calculator before you file.

How is your taxable income — and your liability — worked out?

You are taxed on adjusted profit, not revenue. The starting point is your accounting profit, to which the corporate tax adjustments are applied: add back non-deductible amounts, subtract exempt income, and apply the specific limits in the law. The result is your taxable income, to which the 0% and 9% tiers then apply.

Common adjustments include the 50% cap on entertainment expenditure and the general interest deduction limitation for businesses carrying significant financing costs. Salaries, rent, depreciation and ordinary operating costs are deductible in the normal way. Because the calculation flows straight from your books, the quality of your accounting and bookkeeping directly shapes the liability you end up with.

It is just as important to know what is not deductible. Administrative fines and penalties, the owner’s personal or private expenses, and certain donations to bodies that are not qualifying public benefit entities cannot be set against profit. Mixing any of these into the accounts inflates deductions on paper but weakens the return under review — another reason the discipline of separating business from personal spending pays off directly at year-end.

What income is exempt or relieved from UAE corporate tax?

The genuine reliefs are the 0% threshold, Small Business Relief, the participation exemption, the foreign permanent establishment exemption, the foreign tax credit, and qualifying group relief — not the sector-specific incentives for technology, healthcare or renewable energy that older guidance wrongly claimed. Each must be claimed; none is granted automatically.

There is also a genuinely new incentive worth knowing about. The UAE launched Phase 1 of its R&D Tax Credit on 18 March 2026 (Cabinet Decision No. 215 of 2025 and Ministerial Decision No. 24 of 2026), for tax periods beginning on or after 1 January 2026. It offers a non-refundable credit of up to 50% of eligible R&D expenditure, capped at AED 5 million, with a minimum qualifying spend of AED 500,000 per project. If your business does genuine, systematic research and development in the UAE, this can reduce your liability meaningfully — but the conditions are strict, so assess it carefully rather than assuming you qualify.

Small Business Relief runs to 31 December 2029 — what does that mean for your liability?

Small Business Relief (SBR) is available for tax periods ending on or before 31 December 2029, which means an eligible company can claim SBR for every qualifying tax period up to that date. But it is elective — and if SBR is not elected for a tax year in which you were eligible, it cannot be claimed for future years.

This is the single most valuable liability lever for a small UAE business, and the easiest to lose through an oversight. Under the UAE Small Business Relief rules, where a resident taxable person’s revenue does not exceed AED 3,000,000 in the relevant tax period — and did not exceed it in any previous tax period — the business can elect to be treated as having no taxable income for that period. That is a nil liability, plus simplified compliance and relief from transfer pricing documentation requirements.

It does not remove the obligation to register for corporate tax and file a return, because the election is made inside the return itself. A business that fails to register or file cannot claim the relief, and will face the penalties below even though no tax would have been payable.

The relief was originally set to close after 31 December 2026, so extending the window to 2029 gives a growing small business several more years of a potential nil liability. The catch is procedural, not financial: the benefit is only ever as good as the elections you actually make.

What are the filing and record-keeping obligations?

Three obligations sit behind every liability: register for corporate tax and obtain a Tax Registration Number, file the return and pay any tax within 9 months of your tax-period end, and keep records for at least 7 years. A 31 December 2025 year-end means a 30 September 2026 deadline.

Two corrections matter here, because older guides — including the original of this article — get them wrong. The filing deadline is nine months, not six. And corporate tax records must be kept for seven years, not five; the five-year figure belongs to VAT. Getting either wrong is how a compliant business drifts into penalties without realising it.

The full sequence, in order, is set out in our UAE corporate tax guide for businesses — worth reading before your first year-end, because the obligations behind the liability are where most avoidable penalties arise.

How does transfer pricing affect your liability?

If your business transacts with related parties or connected persons — group companies, shareholders, or their relatives — those transactions must be priced at arm’s length, as if between independent parties, under Ministerial Decision No. 97 of 2023. Pricing that shifts profit artificially can be adjusted upward by the FTA, increasing the tax due.

Documentation scales with size. A related-party disclosure accompanies the return once aggregate related-party transactions pass the disclosure threshold, and larger businesses — broadly those with revenue of at least AED 200 million, and members of large multinational groups above the country-by-country reporting threshold — must maintain a Local File and Master File, produced within 30 days of an FTA request. Even smaller businesses should keep evidence that intercompany dealings are at market rates.

Transfer pricing is one of the fastest-growing areas of FTA scrutiny, and an adjustment can turn a nil or modest liability into a real one. Our UAE transfer pricing support helps set policies and documentation that hold up under review.

What are the penalties for getting corporate tax wrong?

Penalties are automatic, separate from one another, and easy to avoid with timely compliance: AED 10,000 for late registration, AED 500–1,000 per month for late filing, and 14% per annum on late payment from 14 April 2026.

Note the attribution, because it matters: registration and filing penalties sit under the corporate tax decision (CD 75/2023), while the flat 14% per annum late-payment rate comes via Cabinet Decision No. 129 of 2025, effective 14 April 2026, and should never be confused with the separate VAT penalty rules. None of these apply to a business that registers on time, files within nine months, and pays what it owes.

How can you reduce your corporate tax liability — legally?

Lowering corporate tax in the UAE is not about exotic structures. The old reflex of “set up offshore to avoid tax” no longer works and tends to create more risk than it removes. The real savings come from claiming what you are already entitled to, accurately and on time.

Start by capturing every relief: the AED 375,000 nil band, Small Business Relief where your revenue allows, the participation exemption on qualifying shareholdings, and foreign tax credits where income is also taxed abroad. Each is worth real money, and each is missed surprisingly often when a return is rushed at the deadline.

Timing and grouping help too. Forming a tax group can let profits and losses offset within the group, and qualifying group relief lets assets move between group companies without an immediate charge. Above all, clean, IFRS-based accounts are what make each of these defensible. The unifying principle is plain: pay what you owe, claim what you are entitled to, and keep the records that prove both.

What does a real corporate tax liability look like?

Here is the arithmetic on a real trading pattern. Take Karim’s trading company in Dubai, with a 31 December year-end and an accounting profit of AED 700,000 after legitimate business expenses, and no material adjustments.

Karim files and pays AED 29,250 through EmaraTax by 30 September 2026. Had his revenue been AED 2,800,000 — still with the same profit — he could elect Small Business Relief for the period and reduce the liability to nil, and with the window now open to 31 December 2029 he can keep electing it in each eligible year. But if he skipped the election in an eligible year, he would forfeit the relief for every later period too. And if a meaningful slice of his costs were genuine UAE R&D, the R&D credit could reduce the bill further.

The lesson is the same one that runs through the whole liability question: it is rarely just “9% of profit”. It is 9% of profit after the reliefs you are entitled to claim — which is exactly why the return, and the elections inside it, are worth getting right the first time.
