Businesses that operate in the UAE are mandated to comply with corporate tax requirements. While not a core activity, registering for corporate tax registration is critical for operating your business smoothly and avoiding unnecessary financial penalties. This guide outlines what you need to know to register for the UAE Corporate Tax 2025.

What is Corporate Tax in UAE?

Corporate Tax (CT) is a mandatory requirement for businesses that operate within the boundaries of the UAE. The tax is mandated by the UAE Federal Tax Authority (FTA) under the Federal Decree Law 47. It requires all eligible entities in the UAE to register for corporate tax and obtain a Corporate Tax Registration Number (TRN). Once registered and issued the TRN, businesses must submit their Corporate Tax returns and any due taxes within 9 months after every tax period. 

What is a Corporate Tax Registration Number (TRN)?

A TRN is a 15-digit number that is used by the FTA to identify a business that has successfully registered for corporate tax. This number acts as the official tax ID for your business, linking your company to all its tax-related activities such as audits, filings, and payments. 

The TRN will always appear in all tax-related documents of your company, including tax returns and correspondence with the FTA. Consequently, you will not be able to file corporate tax returns or claim deductions without a valid TRN. If your business is eligible and you do not register for corporate tax on time, you could incur fines, delays in compliance approvals, and damage to your business reputation.

For example, if your business license was issued in April (regardless of year), your deadline to register for corporate tax is June 30,2024.
