Understanding Corporate Tax Registration in UAE
Corporate tax registration in the UAE is the process where businesses officially inform the Federal Tax Authority (FTA) that they are earning income and will pay tax according to the rules. It is not optional; every company and eligible freelancer must register once they meet the required criteria.
In simple words, it is like telling the government, “Yes, I am running a business, and I am ready to pay corporate tax on my profits.” Once registered, the business will receive a Tax Registration Number (TRN), which is used for filing corporate tax returns each year.
Who needs to register?
- Companies registered in the UAE
- Branches of foreign companies operating in the UAE
- Freelancers and sole proprietors who earn more than AED 1 million in a year
- Non-resident companies that earn income from the UAE
The UAE has introduced corporate tax to align with global standards, but at the same time, the rate of 9% is one of the lowest in the world, making it business-friendly. Still, deadlines are taken very seriously.

Deadline for Corporate Tax Registration in UAE 2025
The deadline for corporate tax registration in UAE 2025 is a key date every business owner must keep in mind. The Federal Tax Authority has announced that companies must register within the timelines provided, depending on when their business license was issued.
For example:
- Businesses with older licenses (issued before March 2024) have specific deadlines based on the month their license was issued.
- Newly established businesses (after March 2024) must register within three months of incorporation.
If you delay, the FTA may impose fines starting from AED 10,000. This is why it is important to check your license date and register before your specific deadline.
For business owners planning ahead, 2025 is the year when enforcement becomes stricter. Authorities expect every eligible business to be registered and ready for filing returns.
Corporate Tax Filing Deadline 2025
There is a difference between registration deadline and filing deadline.
- Registration deadline: When you must register your business with the FTA and get your TRN.
- Filing deadline: When you must submit your annual corporate tax return, showing your income, expenses, and profits for the year.
The corporate tax filing deadline 2025 will usually be nine months after the end of your financial year. For example, if your financial year ends on December 31, 2024, your first tax return will be due by September 30, 2025.
This means businesses must not only register but also prepare their accounts early to meet filing requirements. Failing to submit on time can lead to penalties just like missing the registration deadline.

Deadlines Based on Business Type
Not every business has the same deadline. The FTA has set different timelines depending on the type of entity.
Freelancers and Individuals
- If your income from business activities is less than AED 1 million, you don’t need to register.
- If your income is AED 1 million or more in a year, you must register within three months of crossing the threshold.
Companies Incorporated Before March 2024
- These companies must register based on their license issuance month. For example, if your license was issued in January, you may have a different deadline than someone whose license was issued in July.
Companies Incorporated After March 2024
- Newly formed companies must register within three months of incorporation.
Non-Resident Companies
- For Non Resident Companies, If a foreign company earns income in the UAE, it must register once it has a permanent establishment or source of income in the country.
By dividing deadlines this way, the FTA makes sure every business is included and no one slips through the cracks.
Penalties for Missing Corporate Tax Registration Deadlines
The UAE takes compliance seriously. If you miss the corporate tax registration deadline, you may face heavy fines.
Some of the penalties include:
- AED 10,000 fine for late registration
- Additional penalties if tax returns are not filed on time
- Possible audits or restrictions on business activities
- Negative impact on your company’s reputation and credibility
These penalties can be a big burden, especially for small businesses or freelancers. That is why registering and filing on time is the safest option.
