UAE Corporate Tax Registration and Filing Deadlines

UAE Corporate Tax has several different deadlines: registration, return filing, payment, record retention and deregistration. Missing one deadline cannot be fixed by meeting another. A company can register on time but file late, or file a return but still incur consequences if the tax is paid late.

The most important recurring rule is straightforward: a taxable person generally files its Corporate Tax return and pays the Corporate Tax due within nine months from the end of its tax period. Registration deadlines, however, depend on the person's type and date of establishment.

Corporate Tax deadlines at a glance

Special rules apply to non-residents, foreign entities managed and controlled in the UAE, tax groups, exempt persons and unusual tax periods.

Registration, filing and payment are separate obligations

Registration creates the taxable person's Corporate Tax account and Tax Registration Number.

Return filing reports the taxable person's accounting income, tax adjustments, reliefs, taxable income and Corporate Tax calculation for a tax period.

Payment settles the Corporate Tax payable. The return and payment share the same general nine-month deadline, but the FTA has clarified that they do not need to be submitted at the same moment.

A business should nevertheless finalise both well before the deadline so payment failures or bank limits can be corrected.

Who generally needs to register?

Registration can apply to:

• UAE mainland companies and other resident juridical persons;
• free-zone companies, including businesses expecting to qualify for the 0% rate;
• foreign juridical persons effectively managed and controlled in the UAE;
• non-residents with a UAE permanent establishment or qualifying nexus;
• natural persons conducting UAE business above the applicable turnover threshold; and
• certain exempt persons when registration is required.

Being registered for VAT does not register the person for Corporate Tax. The application is separate through EmaraTax.

Registration deadline for a new UAE company

A resident juridical person incorporated, established or otherwise recognised in the UAE on or after 1 March 2024 must submit its Corporate Tax registration application within three months from the date of incorporation, establishment or recognition.

This includes free-zone persons. The deadline does not wait for:

• the first sale;
• profitability;
• opening a bank account;
• reaching the VAT threshold; or
• the end of the first financial year.

Example: A UAE company incorporated on 12 May 2026 would generally need to submit its registration application by 12 August 2026.

What about companies formed before 1 March 2024?

FTA Decision No. 3 of 2024 assigned registration deadlines according to the month in which the licence was issued. Those deadlines fell during 2024 and have now passed.

The year in which the licence was issued was irrelevant. Where a person had multiple licences, the earliest-issued licence was used to determine the deadline. An expired licence could still be relevant.

If an older company remains unregistered in 2026, it should not wait for another registration window. Review the late-registration position and submit the application promptly.

Natural-person registration deadline

A resident natural person is generally required to register where total turnover from UAE businesses or business activities exceeds AED 1 million during a Gregorian calendar year.

The registration application is due by 31 March of the following Gregorian calendar year.

Example: If a resident natural person's UAE business turnover first exceeds AED 1 million during 2026, the registration deadline is generally 31 March 2027.

Salary, qualifying personal-investment income and qualifying real-estate-investment income are excluded from the business-turnover test. A natural person with several sole establishments must assess the relevant business turnover collectively rather than treating each licence as an unrelated individual threshold.

Non-resident registration deadlines

For a non-resident juridical person becoming subject to Corporate Tax on or after 1 March 2024:

• a person with a UAE permanent establishment generally registers within six months from the date the permanent establishment exists; and
• a person with a UAE nexus generally registers within three months from the date the nexus is established.

A non-resident natural person whose turnover through a UAE permanent establishment exceeds AED 1 million during a Gregorian calendar year generally registers within three months of meeting the conditions for being subject to Corporate Tax.

Permanent-establishment and nexus analysis is fact-sensitive and can be affected by international agreements. Obtain specialist advice before setting the registration date.

Foreign company managed and controlled in the UAE

A company incorporated outside the UAE can be a UAE resident person if it is effectively managed and controlled in the UAE. Where such status arises on or after 1 March 2024, the registration timeline is generally three months from the end of its financial year.

Board minutes, strategic decisions, management location and decision-making authority can be relevant. Do not assume the foreign incorporation certificate alone decides residence.

How to identify the tax period

For a juridical person, the tax period usually follows the financial year used for financial statements. Common examples include:

• 1 January to 31 December;
• 1 April to 31 March;
• 1 July to 30 June; or
• a first period beginning on the incorporation date and ending on the selected financial year-end, subject to the applicable rules.

Confirm that the financial year on the trade licence, constitutional documents, accounting system, audited statements and EmaraTax profile is consistent. An incorrect tax period produces an incorrect filing deadline.

Return filing and payment deadline

A taxable person generally must submit one Corporate Tax return for each tax period and pay the Corporate Tax due within nine months from the end of that tax period.

The exact date should be confirmed in EmaraTax, particularly for short or long first tax periods and any deadline formally extended by the FTA.

Does a company with no profit still file?

Generally, yes. The filing obligation is not limited to companies with tax payable. A registered taxable person may still need to submit a return where it:

• made a loss;
• had no revenue;
• qualifies for a 0% rate on some income;
• elects for Small Business Relief;
• is dormant but not deregistered; or
• has carried-forward losses or credits.

The return is also how elections, reliefs and tax positions are formally reported.

Free-zone companies and deadlines

Free-zone companies are not outside the Corporate Tax compliance system. They must register and file within the applicable timelines even when they expect to be a Qualifying Free Zone Person and benefit from the 0% rate on Qualifying Income.

A Qualifying Free Zone Person must assess and document:

• adequate substance;
• Qualifying Activities and Excluded Activities;
• Qualifying Income and other income;
• the de minimis requirement;
• domestic and foreign permanent establishments;
• transfer pricing; and
• audited financial statements where required.

Do not postpone that work until the ninth month after year-end.

Small Business Relief does not remove registration deadlines

An eligible resident person may elect for Small Business Relief for a qualifying tax period when the statutory requirements are met. It is an election made through the Corporate Tax return, not an exemption from registration or filing.

A Qualifying Free Zone Person cannot elect for Small Business Relief. Businesses should model the available options before finalising the return.

Corporate Tax groups

Eligible resident juridical persons can apply to form a Corporate Tax group, subject to ownership and other conditions. After approval, the parent company generally files on behalf of the tax group.

Group applications, member additions, removals and cessation can have effective-date requirements. Until an application is approved with the intended effect, each entity should protect its own registration and filing position.

UAE branches of a domestic company

The FTA states that a UAE branch of a UAE domestic company is an extension of its head office and is not a separate legal entity. It therefore does not separately register or file a Corporate Tax return from the domestic parent.

The branch's income and expenses must still be included in the parent company's records and return. Foreign branches and UAE permanent establishments of non-residents require separate analysis.

Registration documents to prepare

The FTA's current Corporate Tax registration service identifies documents such as:

• incorporation certificate, memorandum or partnership agreement;
• commercial registration certificate;
• valid trade licence and branch licences;
• Emirates ID and passport for relevant owners and authorised signatories;
• proof of the authorised signatory's authority; and
• additional documents required for the specific person type.

Check that the legal name, licence information, address, ownership, financial year and authorised signatory match the current corporate records.

Year-round preparation calendar

At the beginning of the tax period

• Confirm the EmaraTax profile and tax period.
• Review accounting policies and opening balances.
• Identify related parties and connected persons.
• Set up tax-sensitive ledger accounts and document retention.

Monthly

• Close the books and reconcile banks, revenue, payroll and VAT.
• Track non-deductible expenses and entertainment costs.
• Document related-party transactions.
• Monitor free-zone qualifying and non-qualifying revenue.

Quarterly

• Prepare a provisional Corporate Tax calculation.
• Review tax losses, interest limitations and relief conditions.
• Update the filing project plan and information requests.

At year-end

• Complete inventory, provisions and cut-off procedures.
• Prepare financial statements and arrange the audit where required.
• Confirm elections and tax-adjustment evidence.

Before the nine-month deadline

• Finalise the tax computation and return review.
• Obtain management approval.
• Submit through EmaraTax.
• Arrange payment early enough to resolve transaction limits or rejected transfers.
• Archive the filed return, calculation and payment confirmation.

Late-registration penalty and waiver initiative

The current FTA service information states that late Corporate Tax registration carries an administrative penalty of AED 10,000.

The FTA also describes a Late Registration Penalty Waiver Initiative. A taxable person can qualify for exemption from the AED 10,000 penalty where it submits its first Corporate Tax return within seven months from the end of its first tax period, subject to the initiative's conditions.

The initiative can cover persons that registered late, have not yet applied, or have already been charged the penalty. If an amount was paid, the FTA states that it can be credited back to the tax account once the conditions are met.

This is an accelerated first-return deadline for waiver purposes. Do not confuse it with the ordinary nine-month statutory filing deadline.

Late return and payment consequences

The FTA has stated that late submission can lead to a penalty of AED 500 for each month or part of a month during the first 12 months, increasing to AED 1,000 for each month or part of a month from the thirteenth month. Other penalties can apply for late payment, inaccurate information or failures under the tax procedures rules.

Penalties can change. Confirm the current Cabinet decisions and EmaraTax assessment rather than relying only on an older summary.

Record-retention deadline

Taxable persons and required exempt persons should retain supporting records for at least seven years after the end of the relevant tax period.

The file should include:

• financial statements and trial balances;
• general ledgers and source documents;
• tax computation and return;
• related-party and transfer-pricing evidence;
• elections, reliefs and exemption support;
• free-zone qualification analysis;
• payment confirmations; and
• FTA correspondence and disclosures.

Deregistration deadline

Corporate Tax registration does not end automatically when a licence expires. A person with a Tax Registration Number must apply for deregistration when its business ceases through dissolution, liquidation or otherwise.

FTA Decision No. 6 of 2023 generally requires natural and juridical persons to apply within three months from the relevant cessation event. All due returns, Corporate Tax and administrative penalties must be addressed before deregistration is completed.

Common deadline mistakes

• Waiting for revenue before registering a new company.
• Assuming VAT registration also covers Corporate Tax.
• Believing free-zone or loss-making companies do not file.
• Using the VAT return calendar for Corporate Tax.
• Calculating nine months from the registration date instead of tax-period end.
• Ignoring the earliest licence when assessing an older company's deadline.
• Applying the resident-natural-person deadline to a company.
• Waiting until the filing deadline to start financial statements.
• Filing without arranging the tax payment.
• Failing to update EmaraTax after ownership or financial-year changes.
