Corporate Tax Registration in the UAE (2026): Who Must Register, Deadlines, Penalty Waiver and EmaraTax Steps

Every company in the UAE must register for corporate tax with the Federal Tax Authority (FTA). That includes free zone companies taxed at 0%, dormant companies and companies that make a loss. A company incorporated in the UAE has three months from incorporation to apply. An individual running a business must register by 31 March of the following year once business turnover passes AED 1 million in a calendar year. Registration is free and done online, on the FTA’s EmaraTax platform.

Applying late costs a fixed AED 10,000. The FTA waives or refunds that penalty if you file your first corporate tax return within seven months of the end of your first tax period, two months ahead of the normal deadline. Below is the position in October 2026, taken from the FTA’s own texts. For how the tax itself is calculated, see our UAE corporate tax basics.

Who must register for corporate tax in the UAE?

Article 51 of Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses (the Corporate Tax Law) requires every taxable person to register and obtain a Tax Registration Number (TRN). That covers:

• Companies incorporated in the UAE, mainland or free zone, whether trading, dormant or loss-making. There is no income threshold for companies.
• Foreign companies effectively managed and controlled in the UAE, for example a company incorporated abroad whose directors meet and decide in Dubai.
• Foreign companies with a permanent establishment in the UAE, such as a branch.
• Foreign companies with a “nexus” in the UAE. Under Cabinet Decision No. 35 of 2025, a foreign company earning income from UAE real estate (rent, sale or other use) has a nexus and must register. A Spanish SL that lets out an apartment it owns in Dubai is caught.
• Individuals whose UAE business turnover exceeds AED 1 million in a calendar year. Salary, personal investment income and personal real estate investment income do not count towards the AED 1 million.
• Some exempt persons. Under FTA Decision No. 15 of 2026, in force since 15 September 2026, qualifying public benefit entities, qualifying investment funds, pension funds and certain wholly owned subsidiaries of exempt entities register on the normal timeline. The funds and subsidiaries then apply for exemption within 90 business days of the end of the tax period.

Employees do not register for their salary. A UAE branch of a UAE company does not register separately: the FTA treats it as part of its head office. For the steps before registration, see our note on company formation in the UAE in 2026.

Corporate tax registration deadlines in 2026

The deadlines come from FTA Decision No. 3 of 2024, in force since 1 March 2024. It still governs: the FTA’s registration page, updated in August 2026, cites it, and Decision No. 15 of 2026 applies its timelines to exempt persons.

Companies that existed before 1 March 2024

These companies had 2024 deadlines set by the month their licence was issued, in any year. All have passed, so a company in this group without a TRN is already late and should apply now.

Where a company holds several licences, the earliest counts. A company with no licence on 1 March 2024 had until 31 May 2024.

Multinational groups: Top-up Tax is a separate registration

Members of large multinational groups subject to the Domestic Minimum Top-up Tax (Cabinet Decision No. 142 of 2024) must also register for Top-up Tax. FTA Decision No. 12 of 2026 gives them seven months from the end of their first in-scope financial year, or until 30 November 2026 where that year ended before 30 April 2026.

The AED 10,000 late registration penalty and the waiver

A late application costs AED 10,000 under item 14 of the table attached to Cabinet Decision No. 75 of 2023, added by Cabinet Decision No. 10 of 2024. It is charged once, and it applies even if the business never owes tax.

The FTA’s Late Registration Penalty Waiver Initiative, running since April 2025, removes the penalty if you file your first tax return (or annual declaration, for exempt persons) within seven months of the end of your first tax period. It covers those who registered late, those who have not yet applied and those already charged. A paid penalty is credited back to the FTA tax account, with no separate request. In May 2026 the FTA said more than 68,600 taxpayers had benefited.

A company that existed before June 2023 and uses a calendar year had 2024 as its first tax period, so on the FTA’s published terms its waiver window closed on 31 July 2025. It should still register now: Article 51(3) of the Corporate Tax Law lets the FTA register a business on its own initiative, backdated to when it became taxable.

How to register for corporate tax on EmaraTax, step by step

The FTA estimates 25 minutes to complete the application and aims to decide within 20 business days of a complete one. There is no fee. The steps follow the FTA’s Corporate Tax Registration User Guide (version 2.0, May 2026).

1. Log in to EmaraTax with UAE Pass or email and password, or sign up. A business registered for VAT already has a taxable person profile; use it.
2. On a new account, add the “Taxable Person” service under “User Type”, then create the taxable person profile with the name in English and Arabic.
3. Open the profile, go to Corporate Tax, open the three-dot action menu and click “Register”. Tick the declaration on the instructions page.
4. Entity details: entity type and sub-type, incorporation date, whether it is a qualifying public benefit entity, constitutional documents, and the tax period. Match it to your financial year: changing it later needs an FTA application under Article 58 of the Corporate Tax Law.
5. Main licence details: upload the trade licence, enter the issuing authority, number, dates and trade name in English and Arabic, add the business activities (one marked primary), the owners, and any UAE branches on the licence.
6. Contact details and authorised signatory: the UAE address, phone and email, then the person signing for the business, through the Emirates ID linked to UAE Pass or with passport details and supporting documents.
7. Review and submit, and keep the reference number. The FTA approves, rejects or asks for more information by email. Once approved, the TRN shows on your dashboard.

Documents you need

• Certificate of incorporation, memorandum of association or partnership agreement, where available.
• Commercial registration certificate, or another official document from the licensing authority.
• Valid trade licence, including branch licences.
• Emirates ID and passport of every owner holding more than 25%, and of each authorised signatory.
• Proof of the signatory’s authority, such as a board resolution or power of attorney.

Files must be PDF, up to 15 MB each, according to the FTA’s registration service page. The FTA’s guide warns that documents which do not match the details entered in the form cause delays, requests for more information or rejection.

When is the first corporate tax return due after registration?

Article 53 of the Corporate Tax Law gives you nine months from the end of each tax period to file the return and pay the tax. For a calendar-year company, the 2025 return was due on 30 September 2026, as the FTA repeated in its press release of 26 September 2026. The 2026 return is due on 30 September 2027.

A late return costs AED 500 for each month or part of a month in the first 12 months, then AED 1,000 a month. Unpaid tax attracts a penalty of 14% a year, charged monthly (Cabinet Decision No. 75 of 2023, items 7 and 8). Both apply on top of any registration penalty.

Small Business Relief: register first, elect in the return

Small Business Relief treats a resident business as having no taxable income if its revenue is AED 3 million or less in the tax period and in every earlier one (Article 21 of the Corporate Tax Law and Ministerial Decision No. 73 of 2023, as amended by Ministerial Decision No. 131 of 2026). It runs for tax periods ending on or before 31 December 2029. You still register and file: the election is made in each tax return. Members of multinational groups and Qualifying Free Zone Persons cannot elect. Our guide to Small Business Relief explains when a business that qualifies should still not elect.

Free zone companies: 0% still means registering and filing

A Qualifying Free Zone Person (QFZP) pays 0% on qualifying income only while it meets every condition in Article 18 of the Corporate Tax Law: adequate substance in the UAE, qualifying income, no election for the standard rate, and compliance with the transfer pricing rules. Decision No. 3 of 2024 names free zone persons expressly, so a QFZP registers within three months like any other company. It files a return every year and, under Ministerial Decision No. 84 of 2025, keeps audited financial statements whatever its revenue.

Deregistration: closing the corporate tax file

Cancelling a trade licence does not cancel the TRN. Under Article 52 of the Corporate Tax Law and FTA Decision No. 6 of 2023, a business applies to deregister within three months of ceasing business, dissolution or liquidation, and is not deregistered until it has filed every return, including a final one up to the date of cessation, and paid all tax and penalties. A late application costs AED 1,000, then AED 1,000 each month, up to AED 10,000 (Cabinet Decision No. 75 of 2023, item 3).

The application is free. For a closure the FTA asks for the licence cancellation document and financial statements up to the cancellation date, and its deregistration service page allows 40 working days for a decision.

What to do now

1. Find your category and deadline in the first table. A UAE company with no TRN is very probably late already.
2. If you registered late or not at all, work out your first tax period and the date seven months after it ends. Filing the first return by then removes the AED 10,000 penalty.
3. Gather the documents before opening EmaraTax and check that names and details match across them.
4. Diarise the return date: nine months after your financial year end.
5. If a foreign company owns UAE property or runs a UAE branch, check the three- and six-month non-resident deadlines.
6. If the business is closing, build the three-month deregistration deadline into the liquidation plan.

Frequently asked questions

Do I need to register for corporate tax if my company makes no profit?

Yes. A UAE company registers whatever its income, including a dormant or loss-making company.

What is the corporate tax registration deadline for a new company?

Three months from incorporation, establishment or recognition, for mainland and free zone companies alike.

Do freelancers and sole establishments have to register?

Only once business turnover exceeds AED 1 million in a calendar year, and then by 31 March of the following year. A sole establishment has no legal personality separate from its owner, so the owner registers as an individual on that test.

Can the AED 10,000 late registration penalty be waived?

Yes, if you file your first tax return within seven months of the end of your first tax period. The FTA applies the waiver, or refunds a paid penalty to your tax account, automatically.

Is VAT registration the same as corporate tax registration?

No. They are separate registrations with separate deadlines. A VAT-registered business uses the same EmaraTax profile but must still apply for corporate tax.
