UAE Corporate Tax Registration Deadline — When You Must Register

When Is the Deadline?

Every business operating in the UAE is required to register for corporate tax with the Federal Tax Authority (FTA). The registration deadline depends on the date of issuance of your trade license or equivalent permit. Unlike a single universal deadline, the FTA has staggered registration windows based on your license month to manage the volume of applications and ensure smoother processing.

If you already have a Tax Registration Number (TRN) for VAT or excise tax purposes, you still need a separate corporate tax registration. Your existing TRN does not automatically cover corporate tax obligations.

Missing the deadline triggers an automatic penalty of AED 10,000 — and there is no grace period. The FTA systems track compliance dates automatically, so late registrations are flagged immediately.

Registration Deadlines by License Month

The FTA has published a timeline that ties your corporate tax registration deadline to the month your trade license was originally issued. Below is the schedule for resident juridical persons (companies):

• License issued in January or February — Deadline: May 31, 2025
• License issued in March or April — Deadline: June 30, 2025
• License issued in May — Deadline: July 31, 2025
• License issued in June — Deadline: August 31, 2025
• License issued in July — Deadline: September 30, 2025
• License issued in August or September — Deadline: October 31, 2025
• License issued in October or November — Deadline: November 30, 2025
• License issued in December — Deadline: December 31, 2025

For companies incorporated on or after March 1, 2024, the deadline is generally 3 months from the date of incorporation. Natural persons conducting business in the UAE with turnover above AED 1 million have a deadline of March 31, 2025 for the 2024 calendar year.

If your license does not include a specific month of issuance, the FTA uses the date your license was first issued or renewed.

What Happens If You Register Late?

Late registration carries a fixed administrative penalty of AED 10,000. This penalty is imposed automatically — you do not receive a warning or an opportunity to correct it before the fine is applied.

Beyond the monetary penalty, late registration can create additional complications:

• Delayed tax filing: You cannot file your corporate tax return until you have a valid corporate tax registration number. Late registration therefore pushes back your filing timeline and may trigger additional late-filing penalties.
• Banking and compliance issues: Some banks and free zone authorities now verify corporate tax registration status. A missing registration can affect banking relationships or license renewals.
• Audit risk: The FTA may flag late registrants for additional scrutiny during compliance reviews.

If you have already missed your deadline, register immediately. While the penalty cannot be waived, prompt registration prevents the situation from compounding.

How to Register — Step by Step

Corporate tax registration is completed online through the EmaraTax portal (the FTA's digital services platform). Here is the step-by-step process:

1. Log in to EmaraTax: Visit the FTA website and access the EmaraTax portal. If you already have an account (for VAT or excise tax), use the same login credentials. If not, create a new account.
2. Navigate to Corporate Tax: From the dashboard, select "Corporate Tax" and click "Register."
3. Enter business details: Provide your company name, legal form, trade license number, license issuing authority, date of incorporation, and business activities.
4. Upload required documents: Attach the documents listed in the section below.
5. Provide ownership details: Enter information about shareholders, partners, or beneficial owners as applicable.
6. Review and submit: Verify all information for accuracy and submit the application.
7. Receive your Tax Registration Number: Upon approval, the FTA issues a corporate tax TRN. This typically takes 5 to 10 business days but can be faster.

Documents Required

Before starting your registration, gather the following documents:

• Trade license (current and valid)
• Certificate of incorporation or equivalent formation document
• Memorandum of Association (MOA) or Articles of Association
• Emirates ID of the authorized signatory
• Passport copy of the authorized signatory (and partners/shareholders if applicable)
• Proof of address (Ejari, tenancy contract, or utility bill)
• Power of Attorney (if a tax agent is filing on the company's behalf)

Free zone companies should also have their free zone authority registration certificate readily available. Some free zones issue a single document that combines the trade license and registration certificate.
