Corporate tax registration in the UAE: deadlines, penalties and reporting obligations

1. Who has to register

The scope is broad and routinely underestimated. Those required to register include:

• All companies incorporated in the UAE — mainland and free zone alike
• Qualifying Free Zone Persons, even though their qualifying income is taxed at nil
• Companies whose profit falls below the AED 375,000 nil-rate band
• Natural persons whose revenue from business activity exceeds AED 1,000,000 in a calendar year
• Foreign companies with a permanent establishment or a nexus in the UAE

2. Deadlines

For newly incorporated companies what counts is the date of incorporation — not the start of trading, and not the end of the first financial year. A company incorporated in March that makes its first sale in October was already required to register in June.

Companies that existed before 1 March 2024 were subject to a schedule staggered by the month of licence issue. Those deadlines all expired during 2024. Anyone still unregistered today should assume the penalty has already been triggered.

3. What happens if you miss the deadline

The penalty for late registration is AED 10,000. It is a fixed amount and applies regardless of whether any tax would have been payable — a company with no revenue and no profit pays it too.

Two points are widely overlooked. The penalty applies per taxable person: a group of five companies that all miss the deadline pays AED 50,000, not AED 10,000. And the registration obligation remains — paying the penalty does not discharge it.

Distinct from the registration penalty are the sanctions for late filing and late payment. Those run separately and are not covered by the waiver described below.

4. Ways to have the penalty waived

The waiver through early filing

With effect from 14 April 2025 the tax authority introduced a relief measure, documented in public clarification CTP006. In essence:

Three limitations matter:

• The waiver applies only to the first tax period. There is no equivalent route for later periods.
• It covers the registration penalty only. Sanctions for late filing or late payment remain.
• It rests on an administrative clarification, not on the statute. It is a time-limited initiative whose continuation is not guaranteed.

As at the date of this guide: for companies whose first financial year ended on 31 December 2025, the seven-month window closed on 31 July 2026. With a different financial year end the calculation has to be done individually. If you want to use this route, check the current position directly with the tax authority — this guide cannot substitute for an up-to-date confirmation.

The ordinary appeal route

Independently of the initiative, the usual route remains: a reconsideration request must be submitted within 40 business days of notification. It requires substantive grounds — a procedural error, or an incorrect factual basis. Simply not having known about the deadline is not enough.

Only the taxable person, their legal representative or a tax agent registered with the authority can submit such a request. If it fails, the next step is the tax disputes resolution committee, where the disputed amount has to be paid up front.

5. Which details you have to keep current

Registration creates a continuing obligation that is easy to lose sight of in practice: the profile held by the authority must match reality.

Under the procedural rules, changes must be notified to the tax authority within 20 business days. Notifiable changes include in particular:

• The name or trading name of the business
• The address of the principal place of business and any other premises
• Email address and contact details
• The main business activity and any other activities
• Renewal or amendment of the trade licence
• The legal form of the company
• Ownership structure and shareholdings
• Details of the authorised signatory
• Expired passport or Emirates ID documents of the individuals on file
• Opening or closing of branches
• Bank details

The most common cause of an unnoticed breach is the annual licence renewal. It produces a new document with a new date and possibly amended activities — and therefore triggers the reporting obligation, even though nothing about the business has changed.

The second most common is an expired Emirates ID or passport for the manager in the profile on file.

Penalties

For failing to notify a change, the corporate tax penalty framework provides for AED 1,000 per breach, rising to AED 5,000 on repetition within 24 months. Different, higher amounts apply for VAT; advisory commentary occasionally conflates the two frameworks.

A transitional period during which the authority waived these penalties ended on 31 March 2025.

Beyond the penalty, an outdated profile has a practical consequence: the authority communicates through the contact details on file. An email address no longer monitored means deadlines and assessments pass unnoticed.

6. Deregistration

Where the business ceases, is dissolved or is liquidated, deregistration from corporate tax has to be applied for. Here too there is a deadline, and here too a penalty applies on default — one that increases month by month.

Important: deregistration presupposes that all returns have been filed and all outstanding amounts settled. A company cannot be closed for tax purposes while arrears remain — simply letting the licence lapse is not enough.
