Corporate Tax Filing Deadline in the UAE

There is one rule and it is arithmetic, not a published calendar. Article 53(1) of the Corporate Tax Law requires the return to be filed with the Federal Tax Authority no later than nine months from the end of the relevant tax period. Article 57 defines the tax period as the financial year, or part of it, for which a return is required. So: take your financial year end, add nine months, and that is your deadline.

This is why no single national date exists and why year-tagged searches mislead. A company with a December year end and a company with a June year end have deadlines six months apart, and both are correct. The one common pattern is that most UAE companies use a calendar financial year, which puts their deadline on 30 September.

The first tax period is the one that trips people up. Under Article 69 the law applies to tax periods commencing on or after 1 June 2023, so an entity with a June-to-May year end had a first period of 1 June 2023 to 31 May 2024 and a first deadline of 28 February 2025, while a calendar-year company's first period was 2024 with a deadline of 30 September 2025. Newly incorporated companies get a first period running from incorporation to their first year end, which can be shorter or longer than twelve months depending on the licence and constitutional documents.

Registration and filing are separate obligations with separate deadlines and separate penalties, and conflating them is the single most common error in this area.

Registration is governed by Article 51 of the Corporate Tax Law and FTA Decision No. 3 of 2024, effective 1 March 2024. Entities that already existed on that date had a deadline set by the calendar month in which their trade licence was issued, irrespective of the year of issue — January and February licences by 31 May 2024, running through to December licences by 31 December 2024. Where a company held several licences, the earliest issuance date governed. Those dates have passed; a business that has still not registered is accruing exposure, not waiting for a deadline.

Entities formed on or after 1 March 2024 have three months from incorporation, establishment or recognition, and that includes free zone entities. A foreign-incorporated company effectively managed and controlled in the UAE has three months from the end of its financial year. A non-resident with a permanent establishment arising after 1 March 2024 has six months from the date the establishment existed; one with a nexus has three months from the date the nexus arose.

Natural persons are on an annual cycle. Article 5 of FTA Decision No. 3 of 2024 requires a resident individual whose calendar-year turnover exceeds the threshold in Cabinet Decision No. 49 of 2023 — AED 1,000,000 — to register by 31 March of the subsequent Gregorian calendar year. That deadline has not been extended: the FTA publicly urged natural persons to register before the end of March 2025 for the 2024 calendar year, and the AED 10,000 penalty applies on the same terms as for companies.

Article 48 requires the corporate tax payable to be settled within nine months from the end of the tax period, or by such other date as the Authority determines. That is the same date as the return, but it is a distinct duty with its own penalty, and filing a return without paying does not stop the clock.

There are no instalments and no advance payments in the UAE regime. The whole liability falls due on one date, which is why the cash planning matters more here than in jurisdictions with quarterly payments on account. Payment is made through the EmaraTax account by the methods the FTA supports there; the payment must be received and allocated to the corporate tax liability, not merely initiated, so leaving a bank transfer to the final day is a genuine risk.

Where payments have been made through withholding tax credits under Article 46 or foreign tax credits under Article 47, those reduce the amount payable rather than the deadline. Where credits exceed the liability, Article 49 allows a refund application through EmaraTax, and Article 49 bis — added by Federal Decree-Law No. 28 of 2025 with effect from 15 October 2025 — allows unused tax credits arising from incentives and reliefs to be claimed under controls to be issued by the Cabinet.

The return is completed inside EmaraTax; there is no downloadable form, no official PDF template and no Excel version to fill in offline. What the FTA publishes instead is the corporate tax return guide describing each schedule. That means the real preparation work is assembling the underlying numbers, and that work has to finish well before the nine-month date.

Penalties come from Cabinet Decision No. 75 of 2023, in force from 1 August 2023 and amended by Cabinet Decision No. 10 of 2024 from 1 March 2024. They are assessed automatically and appear in the EmaraTax account.

A late return costs AED 500 for each month or part month for the first twelve months, then AED 1,000 for each month or part month from the thirteenth. The charge runs from the day after the deadline and repeats on the same date each month, so a return two years late has accrued AED 6,000 in the first year and AED 12,000 in the second. Late payment is charged separately at 14% per annum, applied monthly on the unsettled amount from the day after the due date. The two run together: a business that files late and pays late incurs both.

A return filed on time but wrong costs AED 500, unless it is corrected before the filing deadline expires. Correcting it later means a voluntary disclosure, which carries a 1% monthly penalty on the tax difference. Not disclosing before the FTA notifies an audit is worse: a fixed 15% of the tax difference plus the same 1% per month.

There is no general extension mechanism a taxable person can apply for. Article 53 lets the Authority direct another date and Article 48 allows the Authority to set another payment date, but those are powers held by the FTA, not rights held by the taxpayer. Nothing in the law resembles the automatic filing extensions available in some other jurisdictions.

What has happened, and what fuels the extension searches, is targeted relief rather than a moved deadline. The April 2025 initiative waives the AED 10,000 late registration penalty where the first return is filed within seven months of the end of the first tax period — that is a tighter deadline offered in exchange for penalty relief, not a later one. The FTA has also used its Article 53 power in specific cases, for example for certain categories of taxable person whose first tax period ended early in the regime.

The practical implication is uncomfortable but simple: assume your date is nine months after your year end, and treat any reported extension as applying only to the narrow category it names, dated and sourced. As at 12 August 2026 there is no announced general extension of the corporate tax filing deadline. Verify against the FTA media centre before relying on this for a later period.

The Federal Tax Authority does not charge a fee to file a corporate tax return. Filing happens in your own EmaraTax account and the only amount payable to the Authority is the tax itself, plus any penalties already assessed. Any invoice described as a government filing charge should be questioned.

Professional fees are a separate matter and are not regulated. What a firm charges depends on the size of the entity, whether audited financial statements are required, whether the company is claiming Qualifying Free Zone Person status, whether transfer pricing documentation is in scope, and how much bookkeeping remediation is needed before a computation can be built. Those factors vary so widely that any quoted market rate would be a guess, and this page will not print one.

What is worth checking is status rather than price. Only a Tax Agent approved and registered by the FTA under the Tax Procedures Law may represent a taxable person before the Authority, and the register is public on tax.gov.ae. "Tax consultant" and "corporate tax expert" are marketing terms with no licensing meaning. Note also that appointing anyone does not transfer liability: Article 51 of the Tax Procedures Law places the burden of proving the accuracy of the return on the taxable person.

Several unrelated obligations sit close enough in the calendar to be mistaken for the corporate tax deadline.

VAT is the most frequent confusion. Under Federal Decree-Law No. 8 of 2017 a VAT-registered business files and pays for each VAT tax period by the 28th day following the end of that period — monthly or quarterly depending on the FTA's assignment. That is a completely separate return, a separate liability and a separate penalty regime from corporate tax, even though both are filed in the same EmaraTax account. Excise tax, for the narrow set of businesses that import, produce or stockpile excise goods, runs on its own periodic cycle again.

Ultimate beneficial owner filings are not tax filings at all. UBO registers are maintained with the licensing authority — the Department of Economy and Tourism or the relevant free zone authority — under Cabinet Decision No. 109 of 2023 on the Regulation of Real Beneficiary Procedures, on that authority's timeline. Missing a UBO deadline has no effect on your corporate tax position and vice versa.

Wage Protection System obligations are set by the Ministry of Human Resources and Emiratisation and concern how and when salaries are paid, not tax. Trade licence renewal is set by the licensing authority. None of these move the nine-month corporate tax date.
