UAE Corporate Tax in 2026: What Every Business Owner Needs to Know

Who does UAE corporate tax apply to?

UAE corporate tax is governed by Federal Decree-Law No. 47 of 2022 and applies to every UAE-incorporated company, every free zone company, and every branch of a foreign company with a permanent establishment in the UAE. Mainland LLCs, free zone entities, and foreign branches are all "taxable persons".

Individuals are caught only where they carry on a business. A natural person — a freelancer, sole trader, or sole-establishment owner — falls within corporate tax only if their business turnover exceeds AED 1,000,000 in a calendar year. Salary, personal investment income, and income from personally owned real estate are outside the scope entirely.

Government and government-controlled entities, qualifying public benefit entities, qualifying investment funds, and pension funds can be exempt — but most must apply to the FTA for that status rather than assume it.

The 9% rate, the 0% band — and the new 15% top-up tax

The headline is simple: 0% on taxable income up to and including AED 375,000, and 9% on the portion above it. A company with AED 500,000 of taxable profit pays 9% on AED 125,000 — AED 11,250 — and nothing on the first AED 375,000.

The 9% rate has not changed for 2026. The only "15%" figure in circulation is the Domestic Minimum Top-up Tax (DMTT), introduced by Cabinet Decision No. 142 of 2024 and effective for financial years starting on or after 1 January 2025. It applies a 15% effective rate, but only to multinational groups with consolidated global revenues of at least EUR 750 million. If you are not part of a group that size, the DMTT does not touch you.

In practice, the overwhelming majority of UAE businesses will only ever deal with the 0% band and the 9% rate.

Registration — and the AED 10,000 penalty that caught thousands

Every taxable person must register for corporate tax through the EmaraTax portal and obtain a registration number — even a business that expects to pay 0%. Registration is not optional, and missing the deadline carries a fixed penalty of AED 10,000 (introduced by Cabinet Decision No. 10 of 2024).

For existing companies, the FTA set staggered deadlines through 2024 based on the month the trade licence was first issued — all of which have now passed, which is why so many late registrations have attracted the penalty. For a company incorporated on or after 1 March 2024, the deadline is three months from incorporation.

There is one important relief: the FTA will waive the AED 10,000 penalty — and refund it if already paid — where the business files its first corporate tax return within seven months of the end of its first tax period, rather than the usual nine. If you registered late, filing early is how you recover the penalty.

Small Business Relief — the AED 3 million shelter (until end of 2026)

Small Business Relief, under Ministerial Decision No. 73 of 2023, lets a resident business with revenue of AED 3,000,000 or less elect to be treated as having no taxable income — effectively 0% corporate tax. The test is on revenue, not profit, and it must hold in the current and every previous tax period; breach AED 3 million once and the relief is lost permanently.

The relief is time-limited. As the rules stand, it is available only for tax periods ending on or before 31 December 2026. Unless the Ministry extends it, businesses relying on it should plan for standard corporate tax from 2027.

It is not automatic — you must still register, file a return, and make the election in that return. Qualifying free zone persons and members of large multinational groups cannot use it.

Free zones and the 0% rate — the qualifying free zone trap

A common and expensive misconception is that a free zone company automatically pays 0% corporate tax. It does not. The 0% rate applies only to a "Qualifying Free Zone Person" earning "qualifying income"; any income that does not qualify is taxed at 9% from the first dirham.

To qualify, a company must maintain adequate substance in the free zone, earn income from qualifying activities (defined, for 2026, in Ministerial Decision No. 229 of 2025, which replaced the earlier 2023 list), comply with transfer pricing rules, keep audited financial statements, and stay within the de minimis limit — non-qualifying revenue must not exceed the lower of 5% of total revenue or AED 5 million.

Breach any of these and the company loses qualifying status not just for that year but for the following four tax periods — five years in total. Getting the classification right before you transact is far cheaper than losing it afterwards.

What you can — and cannot — deduct

Corporate tax is charged on accounting profit, adjusted for the law's specific rules. Ordinary business costs incurred wholly for the business are deductible: salaries, rent, depreciation, marketing, professional fees.

Three limits catch businesses out. Net interest is deductible only up to the higher of AED 12,000,000 or 30% of tax-adjusted EBITDA (this cap does not apply to banks, insurers, or natural persons). Entertainment expenses — entertaining clients, suppliers, or partners — are only 50% deductible. And some costs are never deductible: fines and penalties, bribes, dividends paid, corporate tax itself, recoverable input VAT, and donations to entities that are not qualifying public benefit entities.

Related-party transactions must be at arm's length — more on that next.

Transfer pricing — the obligation every group has now

If your business transacts with a related party — a group company, a sister entity, or yourself as owner — those transactions must be priced at arm's length, as if between unrelated parties. This is one of the biggest practical changes the corporate tax law brought, and it applies whether or not you are in a free zone.

The owner-director taking an above-market salary, the company paying below-market rent on a property the owner owns, the management fee charged between two group companies — all are now in scope and can be adjusted by the FTA. Businesses with related-party transactions above AED 40 million must file a disclosure with their return; larger groups must maintain a master file and local file.

Documenting the basis for your related-party pricing before you file — not after the FTA asks — is the defensible position.

When your return is due — and the three penalties for getting it wrong

The corporate tax return must be filed, and the tax paid, within nine months of the end of your financial year. For a 31 December 2024 year-end, the first return was due by 30 September 2025; the earliest returns in the country, for financial years ending 31 May 2024, were due 28 February 2025. Filing and payment fall together — there is no separate payment date.

Three distinct penalties apply, and they are often confused. Late registration is a one-off AED 10,000. Late filing is AED 500 for each of the first twelve months, then AED 1,000 a month. Late payment is an administrative penalty of 14% a year on the unpaid tax, accruing for each month or part-month it stays outstanding, with no cap. None of these are "interest" — they are penalties, and they add up quickly.

The practical lesson: register on time, and close your books well before the nine-month mark.

What actually changed for 2026

For a business that registered and filed back in 2024, the landscape has moved on. The 15% Domestic Minimum Top-up Tax now applies to very large multinationals. A federal e-invoicing programme is coming — a pilot from July 2026, with the first mandatory phase from 1 January 2027 for large businesses, not 2026 as some commentary suggests. And a research and development tax credit took effect from 1 January 2026, giving a non-refundable credit of up to 50% of qualifying R&D spend, subject to pre-approval.

The participation exemption and foreign permanent establishment rules were refined by Ministerial Decision No. 302 of 2024, and Federal Decree-Law No. 28 of 2025 added a mechanism to refund excess tax credits. None of this changes the 9% rate — but it changes the planning around it.

How to legally reduce your UAE corporate tax

Legitimate tax reduction is about structure decided in advance, never concealment after the fact. The levers that actually work: claiming Small Business Relief while it lasts if your revenue is under AED 3 million; structuring genuine free zone activity to qualify for the 0% rate; forming a tax group so profits in one entity offset losses in another; capturing and documenting every deductible expense; and putting transfer pricing support in place before you file.

Every one of these depends on decisions made before the transactions happen. By the time your year-end arrives, the numbers are largely fixed — the most valuable corporate tax conversation is the one you have at the start of the year, not the end of it.
