UAE corporate tax registration deadline: what applies to you

The short answer: three months from incorporation

For a company incorporated, established or recognised on or after 1 March 2024, the corporate tax registration deadline is three months from that date. The rule comes from an FTA decision on registration timeframes that has applied since 1 March 2024, and it covers mainland and free zone companies alike.

The clock starts when your company legally comes into existence, which for most Dubai companies is the date on the first trade license or certificate of incorporation. If two dates could apply, work to the earlier one. What matters is when you submit the application, so there is nothing to gain by leaving it to the final week.

Tax rules are updated from time to time, so we confirm the rule that applies to your company before we prepare the file.

Who has to register for corporate tax

Corporate tax applies to businesses and individuals carrying on business activities under a commercial license in the UAE. In practice, almost every company with a mainland or free zone license needs a corporate tax registration, whether or not it has started trading and whether or not it expects a profit.

Free zone companies are not exempt from registering. A free zone business that meets the conditions to be a Qualifying Free Zone Person can keep the free zone incentives on its qualifying income, but it still registers, keeps records and files a return like any other taxable person.

Some foreign companies and individuals are caught too. A company incorporated abroad but managed and controlled from the UAE, or one with a permanent establishment or other taxable presence here, has its own registration deadline under the same FTA decision. An individual running a business in their own name must register once their business turnover passes the threshold set in the law.

Companies formed before March 2024

Companies that already existed when the FTA decision took effect were given deadlines based on the month their license was issued. All of those dates have now passed. If your company was formed before March 2024 and has never registered, it is already late.

Being late does not make registration optional. The late-registration penalty applies once the deadline is missed, and returns for past tax periods still need to be dealt with. The practical order is to register first, confirm which tax periods are open, and then plan the returns that are due.

If you are buying or taking over an existing company, check its corporate tax registration as part of your due diligence. A missed registration is the company's own obligation, so it is better to find out before you sign than after.

What the AED 10,000 penalty means

The Ministry of Finance (MoF) introduced an administrative penalty of AED 10,000 for businesses that do not submit their corporate tax registration application within the timelines set by the FTA. The Ministry said the amount is in line with the penalty for late registration for value added tax (VAT) and excise tax.

The penalty is for the late application itself. It does not depend on your profit, and it sits apart from the penalties for filing a return late or paying tax late, which are separate obligations.

For a small or newly formed company, AED 10,000 can be far more than the tax it owes in its early years. That is the strongest reason to treat the registration date as fixed, even if you expect to pay little or no tax.

After registration: rates, returns and payment

Once registered, you receive a tax registration number (TRN), which must appear on every corporate tax return. The rate is 0% on taxable income up to AED 375,000 and 9% on taxable income above that.

Each return, and any tax payable, is due within nine months of the end of the tax period. For a company whose financial year ends on 31 December, that means the end of the following September. The FTA advises paying well before the deadline, because bank transfers can take time and a payment that arrives late can attract a late payment penalty.

Filing and payment are separate steps on EmaraTax, so you can file first and pay later, as long as both happen before the deadline. Keeping your bookkeeping current through the year turns the return into a review rather than a rush.

Small Business Relief: why registering still matters

Small Business Relief lets an eligible resident business be treated as having no taxable income for a tax period. It is available where revenue is AED 3 million or less in that tax period and in every earlier one, and it is elected for each tax period rather than applied automatically.

Under Ministerial Decision No. 131 of 2026, the relief has been extended to tax periods ending on or before 31 December 2029. Qualifying Free Zone Persons and members of large multinational groups cannot elect it. We confirm the current conditions before you rely on the relief in a return.

The relief does not replace registration. It is an election made by a taxable person for each tax period, and claiming it means being registered and filing, so the three-month deadline applies to small businesses exactly as it does to larger ones.

How to register on EmaraTax

Corporate tax registration is done online through EmaraTax, the FTA's digital tax platform, which is available around the clock. You sign in with UAE PASS, the national digital identity used for FTA services. The usual flow looks like this:

The FTA reviews the application and may ask for more information before it issues your TRN. Reply to any request promptly and through the same platform, so the application does not stall.

• Sign in to EmaraTax and create or open the taxable person profile for your company.
• Select corporate tax registration and enter the company details exactly as shown on the trade license.
• Add the owners, managers and authorised signatory, with their passport and Emirates ID details.
• Upload the trade license and proof that the signatory can act for the company, such as the memorandum of association (MOA) or a power of attorney.
• Review everything, submit and keep the application reference for your records.

What usually causes delays, and how we help

Delays usually come from small mismatches rather than difficult tax questions. Watch for these before you submit:

Global Sky PRO prepares your registration file, checks each detail against your trade license and MOA, submits the application on EmaraTax with you and follows up on any FTA questions. The FTA decides every registration. Any government charges are paid at cost and shown separately from our service fee, which we quote in writing before work starts.

• Names, numbers or dates typed differently from the trade license.
• An authorised signatory with no document showing their authority.
• Expired passports, Emirates IDs or trade licenses uploaded with the application.
• Ownership details that do not match the MOA.
• Submitting in the last few days, leaving no time to correct a returned application.
