Understanding UAE Business Tax in 2026

What taxes does a UAE business actually pay?

UAE business tax is far lighter than most of the world, but the picture has filled in since 2023. Rather than one big tax, you face a handful of distinct ones, each with its own rules and its own authority. The two that matter to almost every business are corporate tax and VAT; the rest apply only if your activity or size brings you into scope. It helps to separate the taxes that depend on what you sell (excise and customs) from those that depend on how much you earn (corporate tax) or turn over (VAT). Knowing which apply to you is the whole game — and it starts with a clear corporate tax position.

Not sure which of these apply to you? Here is the quickest way to work it out.

1. List what you sell and what you earn — separate physical goods (excise, customs) from earnings (corporate tax) and turnover (VAT).
2. Fix your corporate tax position — every company registers; 0% up to AED 375,000 of profit, 9% above.
3. Check the VAT threshold — register once taxable turnover passes AED 375,000, or voluntarily from AED 187,500.
4. Screen the specialist taxes — excise only if you deal in excise goods, customs only if you import, DMTT only for EUR 750m-plus groups.
5. Register and diarise the deadlines — corporate tax within three months of incorporation, then file everything on time.

How does UAE corporate tax work?

This is the headline shift. The UAE introduced a federal corporate tax under Federal Decree-Law No. 47 of 2022, applying to financial years starting on or after 1 June 2023. The structure is deliberately simple: 0% on the first AED 375,000 of taxable profit, and 9% above that. Before this, only oil and gas companies and branches of foreign banks were taxed, at the emirate level; those legacy regimes still exist for extractive and banking activities, but the federal 9% now covers most ordinary businesses. A Qualifying Free Zone Person can still pay 0% on qualifying income if it meets every condition each year.

Two practical points catch businesses out. First, registration is mandatory for every company, including those that will pay nothing — new companies generally register within three months of incorporation. Second, the 9% applies only to the slice of profit above AED 375,000, not the whole figure. Getting the return right starts with sound accounts, which is why clean bookkeeping matters from day one. See our UAE corporate tax guide for the full picture, and Small Business Relief if your revenue is modest.

What is the 15% top-up tax, and does it affect you?

This is new since the old version of this guide, and it causes a lot of needless worry. The UAE introduced a Domestic Minimum Top-up Tax (DMTT) under Federal Decree-Law No. 60 of 2023 and Cabinet Decision No. 142 of 2024, effective for financial years starting on or after 1 January 2025. It implements the OECD’s Pillar Two global minimum tax: in plain terms, it tops up the tax on UAE profits to an effective 15% — but only for very large groups, namely multinational enterprises with consolidated revenue of EUR 750 million or more in at least two of the previous four years.

How does VAT work for UAE businesses?

VAT arrived on 1 January 2018 at a standard rate of 5%, and it applies to most goods and services, with some supplies zero-rated (such as exports and certain healthcare and education) and others exempt (such as residential rent and some financial services). You must register once your taxable supplies and imports exceed AED 375,000 over twelve months, or you expect to within the next 30 days. Voluntary registration is available from AED 187,500, which lets newer businesses reclaim the 5% they pay on costs.

Once registered, you file VAT returns — usually quarterly, sometimes monthly — through the FTA’s EmaraTax portal and keep accurate records. Returns are due within 28 days of each period’s end. Most businesses find that good VAT registration and filing habits prevent the small errors that trigger penalties.

What is excise tax, and what changed in 2026?

Excise tax applies to a narrow set of goods considered harmful to health or the environment. It first arrived in 2017 and was expanded in 2019. If you do not produce, import or stockpile these goods, it does not touch you — but if you do, 2026 brought a significant change. Tobacco products, energy drinks and electronic smoking devices and liquids remain taxed at 100%. The big change is for sweetened drinks: from 1 January 2026, under Cabinet Decision No. 197 of 2025, the old flat 50% was replaced by a tiered volumetric model linked to sugar content.

What about customs duties and withholding tax?

As a member of the GCC customs union, the UAE applies a unified tariff with a standard 5% customs duty on most imported goods (some categories, such as tobacco and alcohol, are higher). Goods imported into and held within UAE free zones are generally exempt, provided they are not moved into the mainland — one of the practical advantages of a free zone for traders. For most service-based businesses, customs duty simply never arises; importers should build the 5% into their landed cost from the outset.

On withholding tax, the answer is refreshingly short: there is a 0% withholding tax on dividends, interest, royalties and service fees paid to non-residents, so profits can leave the UAE without an extra source-country layer. The one nuance is that, for very large groups, the top-up tax above can affect the overall effective rate on UAE profits even though withholding stays at zero. For ordinary businesses, the 0% headline holds.

How do double taxation agreements help?

The UAE has built one of the world’s largest treaty networks — more than 140 double taxation agreements. These prevent the same income being taxed twice, reduce or remove foreign withholding taxes, and clarify which country taxes what. To claim treaty benefits you usually need to prove UAE tax residency, which is where a Tax Residency Certificate comes in, along with genuine substance and beneficial ownership. For businesses trading across borders, the treaty network is a real, usable advantage rather than a technicality.

Whatever happened to Economic Substance Regulations?

If you remember filing ESR notifications, here is some good news: that obligation has largely ended. Under Cabinet Decision No. 98 of 2024, Economic Substance Regulations no longer apply for financial years ending after 31 December 2022, and related penalties for those periods are cancelled or refunded. ESR still applies for the historic period of 1 January 2019 to 31 December 2022, so any missed filings for those years should still be completed. Going forward, the principle behind ESR — demonstrating real activity in the UAE — now lives inside the corporate tax framework, particularly the substance test for Qualifying Free Zone Persons.

What are the transfer pricing rules?

The corporate tax regime brought in transfer pricing rules aligned with OECD guidelines. The core principle is the arm’s length standard: transactions between related parties must be priced as they would be between independent parties. In practice this means maintaining documentation and disclosing related-party transactions with your corporate tax return; larger groups may also need a local file and master file. Even for smaller businesses, related-party pricing — loans from an owner, fees between sister companies — is an area the FTA looks at, so it is worth getting right alongside your corporate tax filing.

A worked example: Priya’s trading company

Priya runs a mainland trading company in Dubai with around AED 6 million of annual revenue and a healthy profit. Which taxes touch her? She registers for corporate tax and files annually; on profit above AED 375,000 she pays 9%, with the first AED 375,000 at 0%. Her turnover is well over AED 375,000, so she is VAT-registered and files quarterly at 5%. She imports goods, so she pays 5% customs duty at the border. She pays dividends to her overseas co-founder with no withholding tax.

She does not sell excise goods, so excise does not apply; she is far below the EUR 750m mark, so the top-up tax does not apply; and she has no ESR filing to worry about for current years. Her real work is keeping clean books and meeting deadlines — the taxes themselves are straightforward once the bookkeeping is sound.

What deadlines apply, and how do you stay compliant?

The UAE’s taxes are individually simple; the difficulty is keeping track of several deadlines at once. Corporate tax registration and filing, VAT returns, and — if relevant — excise returns each run on their own clock, and the penalties are for missing dates, not for the tax itself.

Corporate tax penalties sit under Cabinet Decision No. 75 of 2023 (as amended by Cabinet Decision No. 10 of 2024); VAT penalties sit under Cabinet Decision No. 129 of 2025. An emerging area to watch is e-invoicing, which the FTA is phasing in — aligning your systems early avoids a scramble later.
