Every taxable person in the UAE must register for corporate tax through the FTA's EmaraTax portal and obtain a Corporate Tax Registration Number, even a business that pays 0% (FTA Decision No. 3 of 2024, Article 2). For existing companies, the registration deadline depends on the month your trade licence was first issued, not on your profit. Miss it and the late-registration penalty is AED 10,000.

This guide sets out who must register, the deadline that applies to you, the penalties for getting it wrong, and how to complete registration on EmaraTax step by step. For the wider picture on rates, free zones and reliefs, read the full UAE corporate tax overview.

Key Takeaways

  • Registration is mandatory for every taxable person, including those below AED 375,000, at 0%, or holding Qualifying Free Zone Person status; the AED 375,000 threshold sets the tax rate, not the duty to register (FTA Decision 3 of 2024, 2024).
  • For resident companies incorporated before 1 March 2024, the deadline runs from your licence-issuance month, between 31 May 2024 and 31 December 2024 (FTA Decision 3 of 2024, 2024).
  • Companies set up on or after 1 March 2024 register within 3 months of incorporation (FTA Decision 3 of 2024, 2024).
  • The late-registration penalty is AED 10,000 (UAE Ministry of Finance, 2024).
  • A penalty-waiver initiative may cancel or refund that AED 10,000 if you file your first return within 7 months of your first tax-period end; this is time-sensitive, so verify current status on tax.gov.ae (Deloitte, on FTA Clarification CTP006, 2025).
  • Your corporate tax return and payment are both due within 9 months of your financial year-end (Federal Tax Authority, 2025).

Who has to register for UAE corporate tax?

Every taxable person must register for corporate tax and obtain a Corporate Tax Registration Number, regardless of income, including companies that fall below the AED 375,000 zero-rate band and Qualifying Free Zone Persons taxed at 0% (FTA Decision 3 of 2024, Article 2). Registration is a duty, not a function of how much tax you owe.

Here is the distinction that trips up most founders. The AED 375,000 figure is a rate threshold: profits below it are taxed at 0%, profits above it at 9%. It is not a registration threshold. A free-zone company on the 0% qualifying rate, a startup running at a loss, and a small trading business all share the same obligation. They must register, even when their eventual tax bill is nil.

The same logic applies to Small Business Relief. Electing for that relief does not remove the duty to register; you register first, then claim the relief in your return. We cover the mechanics in our note on UAE Small Business Relief, and why you still must register. Natural persons running a business sit slightly apart: an individual registers only once business turnover exceeds AED 1,000,000 in a Gregorian year, then by 31 March of the following year (FTA Decision 3 of 2024, Article 5).

Citation capsule: Every taxable person in the UAE must register for corporate tax and obtain a Corporate Tax Registration Number, including businesses below the AED 375,000 zero-rate band and Qualifying Free Zone Persons taxed at 0%, because that threshold sets the rate rather than the duty to register (FTA Decision No. 3 of 2024, Article 2). Natural persons register once business turnover exceeds AED 1,000,000 in a Gregorian year.

What is the corporate tax registration deadline in the UAE?

For resident companies incorporated before 1 March 2024, the registration deadline is fixed by the month the trade licence was first issued, irrespective of the year, running from 31 May 2024 to 31 December 2024 (FTA Decision 3 of 2024, Article 3). The hero table above sets out every month. Profit level plays no part.

The schedule reads off the licence month alone. A licence issued in any January or February carried a 31 May 2024 deadline; a December licence carried 31 December 2024. Where a company holds more than one licence, the earliest issuance date governs (FTA Decision 3 of 2024, Article 3). A business with no licence at all on 1 March 2024 had 3 months, to 31 May 2024.

Companies incorporated on or after 1 March 2024

Newer entities work to a rolling clock, not the fixed table. A UAE-incorporated company set up on or after 1 March 2024, including a Free Zone entity, must register within 3 months of its date of incorporation, establishment or recognition (FTA Decision 3 of 2024, Article 3). A company formed under foreign law but managed and controlled from the UAE registers within 3 months of the end of its financial year.

Non-resident persons and natural persons

Non-residents follow Article 4 of the same decision. A non-resident with a Permanent Establishment that existed before 1 March 2024 registers within 9 months of that establishment; one with a UAE nexus before that date had 3 months from 1 March 2024. A Permanent Establishment created on or after 1 March 2024 gives 6 months. Natural persons over the AED 1,000,000 turnover line register by 31 March of the following Gregorian year (FTA Decision 3 of 2024, Articles 4 and 5).

Citation capsule: Resident juridical persons incorporated before 1 March 2024 must register for UAE corporate tax by a deadline set by their licence-issuance month, from 31 May 2024 for January and February licences to 31 December 2024 for December licences; companies incorporated on or after 1 March 2024 register within 3 months of incorporation (FTA Decision No. 3 of 2024, Articles 3 and 5). Multiple licences are governed by the earliest issuance date.

What is the penalty for late corporate tax registration?

The penalty for failing to register for corporate tax on time is a fixed AED 10,000, introduced by Cabinet Decision No. 10 of 2024, which amended the penalties schedule in Cabinet Decision No. 75 of 2023, effective 1 March 2024 (UAE Ministry of Finance, 2024). It applies once, on missing your deadline, and aligns with the VAT and Excise late-registration penalties.

Late registration is only the first of several penalties in the schedule. Late filing of a return draws AED 500 per month for the first twelve months, then AED 1,000 per month thereafter. An unpaid balance accrues a late-payment penalty of 14% per annum, applied monthly on the amount outstanding. Failing to deregister within the required window costs AED 1,000 per month, capped at AED 10,000 (UAE Ministry of Finance, 2024). The chart below stacks the four.

The penalty-waiver initiative (time-sensitive)

There is currently a route to cancel or recover the AED 10,000. Under FTA Public Clarification CTP006, the Authority may waive the late-registration penalty where it is unpaid, or refund or credit it where already paid, for penalties incurred from 1 June 2023; the initiative took effect on 14 April 2025 (Deloitte, on FTA Clarification CTP006, 2025). The condition is filing your first corporate tax return within 7 months of the end of your first tax period, one month earlier than the standard 9-month deadline, and for the first period only.

Treat this as a moving target, not a standing rule. As a worked example, a first tax period running 1 January to 31 December 2024 means filing by 31 July 2025 to secure the waiver. The relief was reported still active in early 2026, but it is a clarification-based initiative, not a permanent feature of the law. If your first-period deadline is still ahead of you, do not assume the waiver will be open. This guidance is current as at June 2026; verify the latest position on tax.gov.ae before you rely on it.

A separate FTA initiative under Public Clarification CTP006, effective 14 April 2025, may waive or refund that penalty if the first return is filed within 7 months of the first tax-period end, though this relief is time-sensitive and should be re-checked on tax.gov.ae (Deloitte, 2025).

How do you register for corporate tax on EmaraTax?

You register for UAE corporate tax through EmaraTax, the FTA's online portal at tax.gov.ae, in five steps; businesses already registered for VAT or Excise reuse the same login (Federal Tax Authority, 2026). The process issues your Corporate Tax Registration Number on approval. The chart below maps the full flow.

Start by logging in to or creating an EmaraTax account, then select the Corporate Tax tile and choose Register. Enter the entity details: legal type, trade licence number and issuance date, business activities, address and contact. Add ownership and management information, then upload the supporting documents: Emirates ID and passport copies for the owners and the authorised signatory, plus the memorandum of association or proof of authorisation. Submit, and the FTA issues your Corporate Tax Registration Number.

Businesses already registered for VAT or Excise reuse the same login.

When is the UAE corporate tax return due, and what comes after registration?

Your corporate tax return must be filed, and any tax paid, within 9 months of the end of your tax period; a financial year ending 31 December 2024 falls due on 30 September 2025 (Federal Tax Authority, 2025). There are no advance or provisional payments through the year. One combined return covers both filing and settlement.

Two precision points matter here. First, filing and payment do not have to happen on the same day, but both must fall inside the 9-month window. Second, there is no instalment regime: you pay once, in full, by the deadline (Federal Tax Authority, 2025). If you cease trading, you must apply to deregister within 3 months of the cessation, dissolution or liquidation, after clearing all outstanding returns and liabilities. The timeline below maps a standard year.

Corporate tax compliance timeline From the tax-period end of 31 December 2024: the first return filed within seven months by 31 July 2025 may secure the penalty waiver, and the return and payment are both due within nine months by 30 September 2025, with no advance payments. Compliance timeline (worked example) Tax period 1 Jan to 31 Dec 2024 FY end 31 Dec 2024 +7 months file first return for the waiver 31 Jul 2025 +9 months return + payment due 30 Sep 2025 No advance or provisional payments during the year Filing and payment need not be simultaneous, but both fall within 9 months Source: Federal Tax Authority, 24 September 2025; waiver per FTA Clarification CTP006

Citation capsule: A UAE corporate tax return must be filed and any tax paid within 9 months of the end of the tax period, so a year ending 31 December 2024 is due by 30 September 2025, with no advance payments during the year (Federal Tax Authority, 24 September 2025). Filing and payment need not be simultaneous, but both must fall inside the window, and a business that ceases must deregister within 3 months.

Frequently asked questions

Do I have to register for corporate tax in the UAE if I pay 0%?

Yes. Every taxable person must register for corporate tax and obtain a registration number, including businesses below the AED 375,000 zero-rate band and Qualifying Free Zone Persons taxed at 0% (FTA Decision 3 of 2024, Article 2). The AED 375,000 figure sets the tax rate, not the duty to register.

What is the corporate tax registration deadline in the UAE?

For resident companies incorporated before 1 March 2024, the deadline depends on your licence-issuance month, from 31 May 2024 to 31 December 2024 (FTA Decision 3 of 2024, Article 3). Companies incorporated on or after 1 March 2024 register within 3 months of incorporation. Natural persons over AED 1,000,000 turnover register by 31 March of the following year.

What is the penalty for late corporate tax registration?

The penalty for missing your corporate tax registration deadline is a fixed AED 10,000, set by Cabinet Decision No. 10 of 2024 amending Cabinet Decision No. 75 of 2023 (UAE Ministry of Finance, 2024). A time-sensitive FTA initiative may waive or refund it if you file your first return within 7 months of your first tax-period end, so verify current status on tax.gov.ae.

How do I register for corporate tax on EmaraTax?

Register on EmaraTax at tax.gov.ae in five steps: log in or create an account, select the Corporate Tax tile and choose Register, enter your entity and trade-licence details, upload Emirates ID, passport and memorandum of association, then receive your Corporate Tax Registration Number (Federal Tax Authority, 2026). VAT and Excise registrants reuse the same login.

When is the UAE corporate tax return due?

Your corporate tax return and any payment are both due within 9 months of the end of your tax period, so a year ending 31 December 2024 falls due on 30 September 2025 (Federal Tax Authority, 2025). There are no advance payments, and filing and payment need not happen on the same day.
