UAE Corporate Tax 2026: New Registration and Deregistration Rules

The UAE Corporate Tax (UCT) continues to change, and 2026 will see increased emphasis on timely registration, deregistration and compliance. It is essential for businesses in the UAE to be aware of these requirements. Failure to meet a deadline may incur penalties, even if the business has little or no Corporate Tax liability.

Meanwhile, businesses must also ensure that they are not misled by the UAE's regular Corporate Tax rules and the Domestic Minimum Top-up Tax (DMTT) as part of the OECD Pillar Two rules. There are different scope and registration requirements between the two regimes.

What Is UAE Corporate Tax?

UAE Corporate Tax applies to businesses and other entities that fall within the scope of the Corporate Tax Law. Taxable income up to AED 375,000 is subject to a 0% rate, while taxable income exceeding AED 375,000 is generally subject to Corporate Tax at 9%.

Importantly, the AED 375,000 threshold determines the applicable tax rate. It does not mean that a business below this threshold is automatically exempt from Corporate Tax registration. Taxpayers may still have to register with the Federal Tax Authority (FTA) and obtain a Corporate Tax Registration Number. The FTA confirms that Corporate Tax registration is completed through the EmaraTax platform.

Who Needs to Register for Corporate Tax?

The registration requirement depends on the type of taxpayer.

Juridical entities: UAE-based firms and other juridical entities that are subject to the Corporate Tax have to register with the FTA according to the relevant deadline. The exact deadline may depend on the incorporation date and other criteria.

Natural person: A person who runs a business or business activities in the UAE should be registered if total annual business revenues exceed AED 1 million. Revenues from salary, private investments, and real estate investments are excluded from this threshold.

Businesses in Free Zones: Being based in a Free Zone does not mean being exempt from the Corporate Tax registration requirement. Those eligible businesses can enjoy the 0% rate on qualifying income, provided they satisfy the criteria of the Qualifying Free Zone Person status.

What About FTA Decision No. 12 of 2026?

One of the most important points to understand in 2026 is that the newer Pillar Two registration requirements should not be treated as changes to the general Corporate Tax registration system.

The UAE's Domestic Minimum Top-up Tax applies to Constituent Entities that are members of multinational enterprise groups meeting the EUR 750 million global revenue threshold in at least two of the four preceding financial years. The DMTT applies for financial years beginning on or after 1 January 2025.

The FTA has made Pillar Two Top-up Tax registration available through EmaraTax. In-scope MNE groups can manage their UAE obligations through a designated entity or through individual entities, depending on the applicable arrangements.

Therefore, a business should first establish which obligation applies to it:

• Standard Corporate Tax registration applies based on the UAE Corporate Tax Law.
• Pillar Two/DMTT registration applies to entities within the scope of the UAE's minimum tax rules.

When Should a Business Deregister?

Corporate Tax deregistration becomes relevant when a business permanently ceases its taxable activities or otherwise meets the conditions requiring it to leave the Corporate Tax register.

The process should not be treated as an automatic consequence of closing a trade license. The business must complete the relevant tax compliance requirements and submit a deregistration application to the FTA.

The FTA provides Corporate Tax deregistration through EmaraTax. The service is available to entities already registered for Corporate Tax, and the FTA may request additional information before approving the application.

What Needs to Be Completed Before Deregistration?

Before submitting the request, the businesses must review their tax position and usually include the following steps:

• Filing of Corporate Tax returns which have already become overdue
• Payment of any overdue Corporate Tax
• Payment of any administrative penalties due
• Maintenance of tax and accounting records
• Preparation of documentation in support of the reasons for deregistration
• Submission of the application for deregistration using the EmaraTax portal

Deregistration will not absolve businesses from previous tax responsibilities. Documentation is to be kept for the necessary statutory period, and even post-deregistration, the FTA will be able to review past tax periods.

How Does the EmaraTax Process Work?

Corporate Tax registration and deregistration are completed online through the FTA's EmaraTax platform.

• For registration: Create or access the business profile, select Corporate Tax registration, and submit the required details and supporting documents for FTA review.
• For deregistration: Access the Corporate Tax section, select deregistration, and submit the required details and supporting documents.
• FTA review: The FTA reviews the application and may request additional information before completing the process.
• Processing time: A completed deregistration application generally takes 30 business days to process.

Common Mistakes Businesses Should Avoid

Corporate Tax compliance issues often arise from simple misunderstandings. Common mistakes include:

• Considering that there is no need for registration for Corporate Tax since the taxable income is less than AED 375,000.
• Considering that if a business closes its trade license, Corporate Tax registration is canceled.
• Thinking that Free Zone companies with a 0% tax rate do not need any registrations.
• Confusing standard Corporate Tax requirements with the separate Pillar Two/DMTT rules that apply to qualifying MNE groups.

Why Timely Compliance Matters

The UAE tax compliance landscape is evolving, and the FTA is increasingly focusing on timely filing, proper record-keeping, and accurate registration information.

The correct way is to check the business tax status early on, understand the requirements for registration, and keep a clear compliance calendar. Deregistration should also be considered where the business is closing or changing its structure, rather than after the business has ceased trading.
