Understanding UAE Corporate Tax: What You Need to Know
The Background
Until recently, the UAE was globally recognized as a “tax-free” hub. While this remains partly true for personal income tax, the corporate environment has changed since 1 June 2023, when the UAE implemented a federal corporate tax system under Federal Decree-Law No. 47 of 2022.
The Corporate Tax Rate
- 0% on taxable income up to AED 375,000
- 9% on taxable income above AED 375,000
- Free Zone entities: potentially benefit from 0% on Qualifying Income, subject to meeting FTA conditions.
Who Pays Corporate Tax?
Corporate tax applies to:
- Businesses and companies incorporated in the UAE.
- Foreign companies with a Permanent Establishment (PE) or nexus in the UAE.
- Free Zone businesses (with specific exemptions).
- Freelancers and self-employed professionals holding a trade licence.
Exemptions apply to:
- Government entities
- Extractive industries (natural resources)
- Charities and public benefit organizations
- Certain investment funds
Who Should Register for Corporate Tax in the UAE?
One of the most common questions businesses ask is: “Do I need to register for corporate tax in the UAE?”
The answer is yes, if you fall under the category of “Taxable Person.”
Taxable Persons Include:
- UAE companies carrying on business in the UAE.
- Non-residents with a permanent establishment or income source in the UAE.
- Free Zone persons (subject to qualifying criteria).
- Licensed freelancers who earn above the exemption threshold.
Registration Deadlines
- Entities established before 1 March 2024: had pre-set registration deadlines published by the FTA.
- Entities established after 1 March 2024: must register within 3 months of incorporation.
Failure to register on time may result in penalties (though the FTA has announced limited penalty waivers for certain late registrations in 2025).
Key Deadlines for Corporate Tax Filing in 2025
The general rule: Corporate tax returns must be filed within 9 months from the end of the relevant tax period.
- For businesses following Jan–Dec year → Deadline: 30 September 2025.
- For businesses following Apr–Mar year → Deadline: 31 December 2025.
- Other fiscal years → Add 9 months to year-end.
Tip: Mark deadlines in advance and set reminders in your accounting software to avoid last-minute rush
