Corporate tax registration deadlines in the UAE: what still applies in 2026

Search for the UAE corporate tax registration deadline and you will find page after page reproducing a table of dates running from May to December 2024. The table is real. It comes from Federal Tax Authority Decision No. 3 of 2024. The problem is that it is history, and reading it as a live schedule tells you nothing about what you should do now.

This article separates the two questions that actually matter: which rule applies to your company today, and what to do if your deadline has already gone.

Where the rules come from

FTA Decision No. 3 of 2024 was issued on 22 February 2024 and came into effect on 1 March 2024. It sets the timeline for submitting a corporate tax registration application, and it splits businesses by whether they existed before that effective date.

If your company was incorporated on or after 1 March 2024

This is the live rule, and the one that applies to every company formed since. A resident juridical person incorporated, established or recognised under UAE legislation, including a free zone person, must submit the tax registration application within three months of the date of incorporation, establishment or recognition.

A company incorporated under the legislation of a foreign jurisdiction but effectively managed and controlled in the UAE works on a different clock: three months from the end of its financial year.

Three months is short if you are also opening bank accounts, hiring and trying to win your first customers. Put the registration in the first month rather than the third.

If your company existed before 1 March 2024

Your deadline was set by the month your licence was issued, irrespective of the year of issuance. Licences issued in January or February gave a deadline of 31 May 2024. March and April gave 30 June 2024. May gave 31 July, June gave 31 August, July gave 30 September, August and September gave 31 October, October and November gave 30 November, and December gave 31 December 2024.

Two details decide which line applies to you. Where a company holds more than one licence, the licence with the earliest issuance date governs. Where a company had no licence at the effective date of the decision, the deadline was three months from that effective date.

Every one of those dates is in the past. If you are reading this because you are not sure whether you registered, the useful question is no longer when your deadline was. It is whether you have a corporate tax registration now.

Non-resident companies

A non-resident juridical person with a permanent establishment in the UAE that came into existence on or after the effective date has six months from the date the permanent establishment came into existence. Where the connection is a nexus in the UAE rather than a permanent establishment, the deadline is three months from the date the nexus was established. For non-residents that already had a permanent establishment before the effective date, the decision allowed nine months from the date of its existence.

Individuals running a business

A natural person conducting business in the UAE whose total turnover in a Gregorian calendar year exceeds the threshold in the relevant tax legislation must register by 31 March of the following calendar year. This is the rule that catches freelancers and sole operators who assume corporate tax is a company matter. A non-resident natural person in the same position has three months from the date of meeting the requirements.

If you missed your deadline

The decision is explicit that failure to submit the registration application within the stated timelines triggers administrative penalties under Cabinet Decision No. 75 of 2023. Penalty amounts change, so confirm the current figure with the FTA rather than relying on numbers quoted in articles.

What does not change is the direction of travel. A late registration does not improve with age, and the penalty position is not helped by waiting until someone asks. If you are behind, register, then deal with the consequence.

Registration is not the same as filing

Registering puts you on the register. It does not file a return, and it does not calculate anything. The return comes later and depends on accounts that hold up. If you are still working out whether corporate tax applies to you at all, start with what is corporate tax in the UAE.
