UAE Corporate Tax Registration and Filing Deadlines: 2026 Guide

Quick answer: UAE corporate tax has two separate jobs: register when you are required to, then file a return and pay any tax due by the official deadline. A corporate tax return and any payment are generally due within nine months after the end of the tax period. For a period ended 31 December 2025 the Federal Tax Authority reminded businesses that the filing and payment date was 30 September 2026; for a period ending 31 December 2026 the same nine-month rule points to 30 September 2027. Registration deadlines depend on the type of person and when it was established. Confirm both dates in EmaraTax for each legal entity.
Updated 12 November 2026. This is general information, not tax advice. Registration timetables, reliefs and filing processes can change. Use the official Federal Tax Authority pages and take advice on your own facts.
Registration, filing and payment are not the same step
Owners sometimes treat “corporate tax” as a single deadline. The Authority treats it as a sequence. First, a taxable person registers with the Federal Tax Authority on the corporate tax registration service, through EmaraTax. Second, after each tax period, the person files a return and pays any tax due. You can be registered and still have no tax to pay for a period. You can also be required to file even if a relief may apply. Mixing those steps up is how registration dates get missed while everyone watches the nine-month filing date.
Free-zone businesses are not automatically outside the system. Official FTA materials on small businesses and corporate tax note that the registration obligation can apply to free-zone persons as well. A special tax rate, if one applies, does not by itself mean you can skip registration. Exempt persons that are required to register have their own official declaration timetable, which the FTA has also tied to a nine-month window from the end of the financial year.
Who needs to register, and by when
On 11 June 2024 the FTA issued a public clarification on registration timelines for taxable persons. The clarification does not replace the law; it explains the deadlines for different categories, including resident and non-resident juridical persons and natural persons, and it has been in effect from 1 March 2024 unless it says otherwise.
The rule that matters for most new UAE companies is this: a resident juridical person incorporated, established or otherwise recognised in the UAE on or after 1 March 2024 generally has to submit a tax registration application within three months of that incorporation, establishment or recognition. That is the official three-month clock. If you formed a company in August 2026, do not wait until the first accounts are finished to think about registration.
Companies established earlier do not all share one date. The FTA published a detailed timetable, in its decision on specified timeframes and in the same clarification, that depends on legal form, place of incorporation and, for many resident companies, the month in which the licence was issued. This article does not reproduce that full historic table, because the relevant date for those entities may already have passed and the official text is the only safe source. If you are dealing with a company formed before 1 March 2024, look up the official timetable for that entity rather than borrowing a three-month rule that was written for later companies.
Non-resident juridical persons have different official clocks again, depending on whether they have a UAE permanent establishment or a nexus, and on whether that presence existed before or after 1 March 2024. The clarification describes, for example, a six-month period from the existence of a permanent establishment for certain non-residents on or after 1 March 2024. If an international agreement gives a longer period for recognising a permanent establishment, the FTA has said that the agreement prevails. This is specialist territory: get advice and use the official clarification, not a shortened blog summary, if a non-resident entity is in the deal.
Natural persons are tested on turnover, not on whether they “feel like a company”. The FTA’s clarification states that, starting from 1 January 2024, a resident natural person must apply to register if turnover from businesses or business activities in the UAE exceeds AED 1 million in a Gregorian calendar year, and that the application is then due by 31 March of the following year. A non-resident natural person with a UAE permanent establishment is also tested against the AED 1 million turnover figure, with a three-month application period once the official conditions are met. Salary and purely personal investment income are not automatically business turnover; the official definitions decide what counts.
When the return and payment are due
The filing rule is easier to state than the registration timetable, but it still depends on the entity’s own tax period. On 26 September 2026 the FTA issued a reminder that 30 September 2026 was the deadline for filing tax returns and paying corporate tax for a financial year ended 31 December 2025. In that announcement the Authority said taxable persons must file returns and pay any tax due within a period not exceeding nine months from the end of each tax period, and that this includes persons eligible for Small Business Relief. Exempt persons that must register should also submit their annual declarations within nine months of the end of their financial year. Registration, filing and payment are all done through EmaraTax, and the Authority notes that approved tax agents can assist.
Apply the same nine-month arithmetic to later periods. If a company’s tax period ends on 31 December 2026, nine months later is 30 September 2027. If the financial year ends on 31 March 2027, nine months later is 31 December 2027. Always confirm the date in the entity’s EmaraTax account, because the official due date follows that entity’s tax period, not a generic calendar someone copied from a neighbour’s company.
The FTA has also stressed record-keeping. In an official reminder it said the records must allow the Authority to verify revenue, taxable income and, where relevant, eligibility for relief, and that relevant records must be retained for at least seven years after the end of the tax period to which they relate. Typical records include a record of transactions, assets (including purchases and disposals), liabilities and shares held at the period end. The exact list depends on the business.
Small Business Relief does not cancel the return
Some owners hear “relief” and stop filing. That is not what the FTA has said. The 26 September 2026 filing reminder expressly included persons eligible for Small Business Relief among those who must file and pay any tax due within nine months. Relief, where it is available, is generally claimed by an election in the return, subject to official conditions such as a revenue ceiling. The conditions themselves have been updated by later ministerial decisions, so this article does not restate an end date or a full eligibility list. If you think the relief applies, read the current official corporate tax topic pages and take advice before you elect, and still build the filing date into your calendar.
What this means if you are buying or selling a business
Corporate tax follows the legal person. A buyer of a company buys its tax history; a buyer of assets may be starting a new tax period in a different entity, but still needs to know whether the seller has unmet obligations that could delay a licence transfer or a handover. Ask for:
- the tax registration number and the date registration was completed;
- the tax period and financial year-end;
- returns, payment receipts and any official correspondence for every period since the company became a taxable person;
- any relief or other elections, and the revenue figures used to support them;
- open queries, assessments or penalty notices, if any;
- who holds the EmaraTax login and how it will be transferred in a controlled way.
Then have those papers reviewed. Do not take “we don’t pay corporate tax” as the end of the conversation. It may be true, or it may mean a return was never filed.

How to value a business in Dubai is the place to think about profit and key money; outstanding tax filings belong in the same pack, because they affect what a buyer is really taking on.

A practical compliance calendar
- For each legal entity, record the incorporation or recognition date, licence date, legal form and financial year-end.
- Use the FTA public clarification and the registration service to identify the registration deadline that actually applies to that entity.
- Register early on EmaraTax and store the tax registration number and access details securely.
- After each period end, close the books, reconcile accounting profit to the tax computation, and collect support for any elections.
- File the return and pay any tax due at least several weeks before the nine-month date, not on the day itself.
- Keep the records for at least seven years after the period ends.
- If you are buying or selling, add the tax file to due diligence and get an adviser to read it.

Key takeaways
- Registering for corporate tax and filing a return are separate official steps. One can be required even when no tax is payable.
- New resident companies incorporated, established or recognised on or after 1 March 2024 generally have three months to apply to register. Older companies, non-residents and natural persons use other official deadlines.
- Resident natural persons generally have to register if business turnover exceeds AED 1 million in a calendar year, with the application due by 31 March of the following year, according to the FTA clarification.
- Returns and any tax due are generally payable within nine months after the tax period ends. The FTA reminded businesses that 30 September 2026 was the deadline for periods ended 31 December 2025. A 31 December 2026 year end points to 30 September 2027.
- Small Business Relief, if it applies, does not by itself cancel the duty to file.
- Buyers should ask for the tax registration, returns, elections and any open FTA issues before they commit.
Frequently asked questions
Does registering for corporate tax mean the company will owe tax?
No. Registration and tax liability are different. The Federal Tax Authority has made clear that taxable persons must file a return even where Small Business Relief is relevant, and a filed return may still show no tax payable. Do not treat a tax registration number as proof that a bill is due, and do not treat the absence of a payment as proof that registration was unnecessary.
Is every UAE company’s registration deadline the same?
No. The FTA’s public clarification on registration timelines sets different dates by legal form and by when the person was established or recognised. For a resident juridical person incorporated, established or recognised in the UAE on or after 1 March 2024, the usual rule is to apply within three months of that event. Older companies, non-residents and natural persons follow other official timetables. Check the clarification and the EmaraTax service for the exact entity.
When is the corporate tax return due?
The FTA has stated that taxable persons must file the tax return and pay any corporate tax due within a period not exceeding nine months from the end of the tax period. For a period that ended on 31 December 2025, the Authority reminded businesses that the deadline was 30 September 2026. For a period ending on 31 December 2026, the same nine-month rule points to 30 September 2027. Always calculate from the entity’s own tax-period end and confirm the date in EmaraTax.
Can a small business skip filing if it expects to pay no tax?
Do not assume so. The FTA’s 26 September 2026 reminder said that taxable persons, including those eligible for Small Business Relief, must still file returns and pay any tax due within nine months of the period end. Relief, if it applies, is usually an election inside the return, not a reason to stay silent.
How long must corporate tax records be kept?
In an official reminder on record-keeping, the FTA stated that both taxable persons and exempt persons must retain relevant records for at least seven years following the end of the tax period to which they relate. The exact documents depend on the business, but they need to support the figures in the return.
What should a buyer ask before purchasing a UAE company?
Ask for the tax registration number, the tax period, evidence that registration was filed on time, copies of returns and payments, any relief elections, and a list of open FTA queries. Then have an adviser review them. This sits alongside the licence, lease and sales checks in our guides on how to buy a business in Dubai and how to buy a company in Dubai.
