(Rates, Registration, Filing, Exemptions & Compliance)

The introduction of a federal corporate taxation regime in the UAE in mid-2023 has become one of the major shifts in the fiscal environment. As a company with presence in the UAE, whether on the mainland, free-zone, local, foreign subsidiaries or multinational business, it is essential to understand the mechanisms of corporate tax compliance and tax optimization.

You must stay in the game, even though you have a small business, or a free-zone organization that is not subject to any tax on a specific income at zero percent (0%), you still have to be on the right side of the law, by registering, filing returns, and maintaining a

well-organized document.

What is Corporate Tax?

Corporate Tax (CT) is a direct tax that is imposed on the net profit (taxable income) of the companies and other taxable individuals in the UAE. CT became effective on 1 June 2023 on all financial years beginning on or after that date with the introduction of Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses.

This implies that a majority of businesses including newly formed enterprises need to know their liabilities in terms of corporate tax and they should comply.

UAE Corporate Tax Rates (2026)

In the case of 2026, the UAE corporate tax will be organized as follows:

• 0%: charged on the taxable income up to AED 375,000.
• 9%: is charged on taxable income exceeding AED 375, 000.

This pyramid system is created to ensure that small businesses, start up, and SMEs are relieved of excessive tax loads without compromising the government ability to generate income in a justifiable way.

What about Large Multinationals?

The UAE has implemented a Domestic Minimum Top-Up Tax (DMTT) to be effective as of 1 January 2026 to large multinational enterprise (MNE) groups that have global consolidated revenues of EUR750 million or above (in two out of the last four financial years). This guarantees a minimum level of effective tax rate (ETR) of 15% on their operations in UAE as per the international standards of tax transparency.

Therefore, as most business activities will continue to pay the standard 9 per cent rate, some of the large multinational corporations will be subject to a high effective rate under DMTT starting in 2026.
