The corporate tax registration deadline in the UAE is set by the Federal Tax Authority (FTA) and depends on when a company was incorporated, when a trade license was issued, or when an individual exceeds the AED 1 million business income threshold. Companies incorporated before March 1, 2024 faced staggered deadlines across 2024. New companies must register within three months of incorporation, while natural persons have until March 31 of the following year once they cross the threshold. Missing the deadline can result in penalties, making timely compliance essential.
Why Corporate Tax Registration is Essential for UAE Businesses
Corporate tax registration is not only a legal obligation but also a practical necessity. Without a Tax Registration Number (TRN):
- Businesses cannot file corporate tax returns or claim reliefs.
- License renewals, government tenders, and banking requirements may be delayed.
- Companies risk reputational damage with regulators, lenders, and partners.
Even free zone companies that enjoy a 0% rate on qualifying income must still register. Registration ensures transparency and confirms eligibility for reliefs such as the Small Business Relief.
For a full breakdown of who is a taxable person, exemptions, and thresholds, see our separate blog: Who Must Register for UAE Corporate Tax.
UAE Corporate Tax Rate Overview
While this article focuses on deadlines, it helps to understand the context. The UAE corporate tax applies at a 9% rate on taxable profits above AED 375,000. Profits up to that threshold are taxed at 0% to support small businesses. Certain exempt persons, like qualifying public benefit entities or investment funds, may enjoy exemptions but are often still required to register to obtain a TRN.
Corporate Tax Registration Deadlines in 2025
The FTA issued Decision No. 3 of 2024 to specify clear timelines for when different categories of taxpayers must apply for registration.
Resident Companies (Juridical Persons)
If a company was incorporated before March 1, 2024, the registration deadline depends on the month its trade license was issued:
| Trade License Issue Month | Registration Deadline |
|---|---|
| Jan – Feb | 31 May 2024 |
| Mar – Apr | 30 Jun 2024 |
| May | 31 Jul 2024 |
| Jun | 31 Aug 2024 |
| Jul | 30 Sep 2024 |
| Aug – Sep | 31 Oct 2024 |
| Oct – Nov | 30 Nov 2024 |
| Dec | 31 Dec 2024 |
No trade license as of March 1, 2024: deadline was 31 May 2024.
Incorporated on or after March 1, 2024: must register within three months of incorporation.
Foreign entities managed and controlled from the UAE (Place of Effective Management): must register within three months from the end of their first financial year as UAE tax residents.
Important: if a company holds multiple licenses, the earliest license issuance date applies.
Non-Resident Companies
For non-resident entities, the deadline depends on whether they have a permanent establishment (PE) or a nexus in the UAE. A nexus means having a sufficient business connection to the UAE even without a physical office, for example, earning income from property located in the UAE (Cabinet Decision No. 56 of 2023).
| Scenario | Registration Deadline |
|---|---|
| PE before 1 Mar 2024 | 9 months from PE creation |
| PE on/after 1 Mar 2024 | 6 months from PE creation |
| Nexus before 1 Mar 2024 | 31 May 2024 |
| Nexus on/after 1 Mar 2024 | 3 months from nexus date |
| Non-residents with only UAE-sourced income (no PE/nexus) | Not required (Ministerial Decision No. 43 of 2023) |
The date of existence of a PE depends on its type:
For a fixed place PE (such as an office, branch, or workshop), it is generally treated as existing from the start of business activity.
For a construction PE, it is considered to exist once the project exceeds six months.
Because interpretation can vary in practice, the safest approach is to register as soon as you begin UAE activities that could create a PE.
Individuals (Natural Persons)
- Residents: Must register by March 31 of the following year if business turnover exceeds AED 1 million in a calendar year.
- Non-residents: Must register within 3 months of exceeding AED 1 million in UAE-sourced business income.
This requirement applies only to business and commercial income. Personal income such as salaries, dividends, or private real estate income is outside the scope of corporate tax.
Administrative Penalty for Late Registration
Failure to apply within the deadlines results in a fixed AED 10,000 penalty under Cabinet Decision No. 10 of 2024. Importantly, the FTA clarified that the deadline applies to submitting the application, not to the issuance of the TRN itself. In 2025, the FTA introduced a waiver scheme: businesses that missed registration can avoid or reclaim the AED 10,000 fine if they file their first corporate tax return within seven months of their first tax period’s end.
For most businesses with a December 31, 2024 year-end, this means filing by July 31, 2025. To benefit from the waiver, companies must submit their first return on time. This makes it essential to track the official corporate tax filing deadlines in the UAE as carefully as registration deadlines.

Required Documents for Registration
The FTA requires different documents depending on whether the applicant is a company or an individual.
Juridical Persons
- Trade license
- Memorandum of Association (MOA) or similar incorporation documents
- Emirates ID and passport copy of authorized signatory
- Shareholder details
- Registered business address and contact details
- Financial period start and end dates
- Bank account information (optional but recommended)
- Financial statements for larger entities
Natural Persons
- Emirates ID or passport
- Trade license or commercial permit
- Financial records showing business income (invoices, profit and loss statements)
- Residential address and contact details
Note: A valid trade license must be uploaded and accepted on the EmaraTax portal before completing the registration application.
Step-by-Step Registration Process
1. Prepare documents as above.
2. Log in to EmaraTax (or create an account if you do not have one).
3. Fill out the corporate tax registration form, providing business details and uploading documents.
4. Nominate an authorized signatory and upload identification.
5. Submit the application. The deadline refers to this submission date, not when the TRN is issued.
6. Await FTA review (usually up to 20 business days).
7. Receive TRN once approved.
Tax groups must apply separately for group status, but deadlines remain unchanged from previous rules.

Frequently Asked Questions
Does the AED 10,000 penalty apply if I submit on time but my TRN is issued later?
No. The deadline applies to submission of the application, not issuance of the TRN.
Do dormant or inactive companies need to register?
Yes. If a company holds a trade license, registration is required even if it has no activity.
What about companies with unusual financial years, such as July–June?
In rare cases, a non-resident with a July–June year could have faced a March 31, 2024 deadline (nine months after July 1, 2023). Businesses in this position should confirm obligations with the FTA.
Is registration required for free zone companies?
Yes. All juridical persons incorporated in the UAE must register, even if they enjoy a 0% tax rate.
Can I deregister if I close my business?
Yes. Businesses can apply for deregistration in EmaraTax if they cease taxable activities. The FTA must approve the request.
