Corporate Tax registration deadline in the UAE (2026)
You must register for UAE Corporate Tax by a deadline that depends on when your trade license was issued, regardless of how much profit you make. Missing it triggers an administrative penalty. Here is how the deadlines work and how to stay ahead.
Every taxable business must register
Corporate Tax registration is not optional for taxable persons. Whether you are Mainland or Free Zone, and even if your profit is below AED 375,000 (and therefore taxed at 0%), you still have to register and obtain a Corporate Tax registration number.
How the deadline is set
For many businesses the FTA set registration deadlines based on the month your trade license was issued. New businesses have a set window after incorporation. Because timelines vary by situation, check your specific deadline in EmaraTax rather than assuming.
The penalty for late registration
Registering late for Corporate Tax carries an administrative penalty (AED 10,000). This applies even if you owe no tax, so registration is about compliance, not just payment.

Try free for 1 monthRegistering does not mean you owe tax
A common misunderstanding: registering for Corporate Tax does not mean you immediately pay it. If your profit is below AED 375,000 you are taxed at 0%, but you must still be registered and file a return.
