UAE corporate tax registration deadline: dates, rules, and penalties

What is the UAE corporate tax registration deadline?

The UAE corporate tax registration deadline is the date by which a taxable person must submit a corporate tax registration application to the Federal Tax Authority (FTA) through EmaraTax. For resident juridical persons holding a licence before March 1, 2024, the deadline depends on the month the licence was issued, ignoring the year of issue. Missing it triggers a fixed administrative penalty.

Corporate tax was introduced under Federal Decree-Law 47 of 2022. The standard rate is 9% on taxable income above AED 375,000, with 0% below that threshold. Knowing your registration deadline is the first compliance step, and it sits at the centre of our wider UAE Corporate Tax guidance.

Who needs to register for UAE corporate tax?

Almost every business in the UAE must register, even if it expects to pay no tax. The FTA requires registration from resident juridical persons, qualifying free zone persons, non-resident persons with a permanent establishment or nexus, and certain natural persons running a business.

Resident juridical persons

Mainland LLCs, private and public joint stock companies, and other UAE-incorporated entities must register. This applies whether the company is profitable, dormant, or under liquidation. If you hold a trade licence, assume you must register.

Free zone companies

Free zone entities must register regardless of whether they qualify for the 0% rate as a Qualifying Free Zone Person (QFZP). For specifics, read our guide on Corporate Tax Registration for Free Zone Companies.

Natural persons running a business

Individuals conducting a business or business activity in the UAE must register if their total turnover exceeds AED 1,000,000 in a Gregorian calendar year. Salary, personal investment, and real estate investment income are excluded.

Non-resident persons

Foreign companies with a permanent establishment in the UAE, or with a UAE nexus through immovable property, must register. The timeline for non-residents differs from the licence-based schedule used for residents.

The UAE corporate tax registration deadline by licence month

FTA Decision 3 of 2024 sets the registration timeline. Resident juridical persons that held a licence on March 1, 2024 follow a schedule based on the month their earliest licence was issued. The year of issue does not matter. If the entity holds multiple licences, the earliest issue date is used.

The headline penalty for missing the deadline is AED 10,000, set out in Cabinet Decision 75 of 2023 as amended by Cabinet Decision 10 of 2024.

For entities incorporated on or after March 1, 2024, the deadline is three months from incorporation. Non-resident persons with a permanent establishment created before March 1, 2024 had nine months from the establishment date. Natural persons running a business must register by March 31 of the year following the year in which turnover exceeded AED 1,000,000.

What happens if you miss the registration deadline

Late registration carries an administrative penalty of AED 10,000. The penalty applies once per taxable person, not per month of delay. It is issued automatically once the FTA processes a late application.

The penalty waiver initiative

The FTA and Ministry of Finance announced a waiver of the AED 10,000 late registration penalty for taxable persons that submitted their corporate tax return or annual declaration within seven months of the end of their first tax period. The waiver applies to the first tax period only. Businesses that already paid the penalty under qualifying conditions can have it refunded to their EmaraTax account.

To benefit, you must still register, file the first return on time, and meet the seven-month rule. If you have not yet registered, follow our step-by-step process on How to Register Corporate Tax UAE Online.

Other consequences

Beyond the fixed penalty, late registration can trigger late filing and late payment penalties on the first return. It can also delay your Tax Registration Number (TRN), which you may need for contracts, tenders, and banking checks. For full registration instructions, see our UAE Corporate Tax Registration guide.

How to register before the deadline

Registration is done online through EmaraTax, the FTA's tax portal. There is no government fee to register. If you appoint a tax agent, you pay only their professional fee. See our breakdown of UAE Corporate Tax Registration Cost for details.

Step 1: Prepare your documents

Gather the trade licence, passport and Emirates ID copies of authorised signatories and owners, the Memorandum of Association, contact details, and bank information. The full list is on our Corporate Tax Registration Documents Required page.

Step 2: Log in to EmaraTax

Use your existing EmaraTax credentials, or create an account on the Federal Tax Authority portal. VAT-registered businesses already have a profile; corporate tax registration is a separate application linked to the same taxable person.

Step 3: Complete the application

Select Corporate Tax, choose the entity type, and fill in licence and ownership data. Submit supporting documents and review the financial year end carefully. Once approved, the FTA issues a corporate tax TRN, usually within 20 business days. A full walkthrough is in our EmaraTax Corporate Tax Registration Guide.

After you register: filing and payment deadlines

Registration is only the first step. Every registered taxable person must file a corporate tax return and pay any tax due within nine months of the end of the relevant tax period. For a financial year ending December 31, 2024, the first return and payment are due by September 30, 2025.

Even loss-making and dormant entities must file. Small Business Relief is available for businesses with revenue up to AED 3,000,000 in the relevant and previous tax periods, applicable through tax periods ending on or before December 31, 2026.

Common mistakes that cause missed deadlines

• Using the year of licence issue instead of the month to read the schedule.
• Assuming free zone entities are exempt from registration.
• Treating dormant or holding companies as out of scope.
• Waiting for FTA correspondence instead of registering proactively.
• Forgetting that branches share the parent's TRN but the parent must still register.
• Not updating the licence record after a trade name or activity change.

If your earliest licence was cancelled and reissued, the FTA generally looks at the earliest still-valid licence. When in doubt, refer to the UAE Ministry of Finance guidance or contact the FTA before the deadline lapses.

How the registration deadline connects to e-invoicing

Corporate tax registration is a separate process from the upcoming UAE e-invoicing mandate, but they share the same regulator and portal infrastructure. The UAE e-invoicing regime uses the Peppol 5-corner DCTCE (Decentralized Continuous Transaction Control and Exchange) model, with Phase 1 mandatory go-live on January 1, 2027 for businesses with revenue of AED 50,000,000 or more. Registering for corporate tax on time keeps your taxable person profile clean and ready for e-invoicing onboarding. For background on the wider framework, see our UAE Corporate Tax hub.
