How to File a UAE Corporate Tax Return: Deadlines, Payment and Requirements

Last reviewed: 26 July 2026

Every Taxable Person must understand two separate deadlines: the deadline to file the Corporate Tax Return and the deadline to pay any Corporate Tax due. Both are generally nine months from the end of the relevant Tax Period, but the return and payment do not have to be completed at the same moment.

A company that made a loss or has no Corporate Tax payable must still file if it is a Taxable Person. This guide explains who files, how the Tax Period and deadline are identified, what information should be prepared and how the return and payment are completed through EmaraTax. For the wider framework, read our UAE Corporate Tax Guide 2026.

The Quick Answer

• The return is generally due within nine months from the end of the Tax Period.
• Corporate Tax payable is generally due by the same nine-month deadline.
• The return and payment can be completed separately, but both must be received by the applicable deadline.
• A domestic UAE branch does not file separately from its UAE parent company.
• The parent company files on behalf of an approved Corporate Tax Group.
• Certain Exempt Persons required to register submit an Annual Declaration rather than an ordinary Corporate Tax Return.

Who Must File?

Every person that is a Taxable Person for a Tax Period must file the required Corporate Tax Return. This includes UAE companies, Free Zone Persons, Non-Resident Persons within the filing rules and natural persons whose businesses are subject to Corporate Tax.

Filing depends on the person’s Corporate Tax status, not on whether tax is payable. A person that has not completed registration should first review our guide to UAE Corporate Tax registration.

Branches, Tax Groups and Exempt Persons

• A UAE branch of a domestic company is included in the parent company’s return and does not file separately.
• The parent company of an approved Tax Group files a single return on behalf of the Tax Group.
• Certain Exempt Persons required to register submit an Annual Declaration within the applicable timeframe rather than a standard Tax Return.
• A foreign company with a UAE Permanent Establishment files according to the non-resident person’s UAE Corporate Tax position.

How Is the Tax Period Identified?

The Tax Period is generally the Financial Year for which the person prepares financial statements. It may be the Gregorian calendar year or another 12-month accounting period.

For a newly established company subject to the Commercial Companies Law, the first Financial Year can generally be between six and 18 months. If that first Financial Year begins on or after 1 June 2023, it is generally accepted as the first Corporate Tax Period. If it began before 1 June 2023, the first Corporate Tax Period is normally the next Financial Year beginning on or after that date.

The person should verify the period displayed in EmaraTax against its incorporation documents, accounting records and registration details before starting the return. Incorrect registration information may need to be amended before the return can be completed.

What Is the Filing and Payment Deadline?

A Corporate Tax Return must generally be filed no later than nine months from the end of the relevant Tax Period. Corporate Tax payable must also generally be settled within nine months from the end of that period.

These examples assume that no special extension or different approved Tax Period applies. The return and payment can be made on different dates, but both must be completed by the deadline.

Must a Company File If It Made a Loss?

Yes. A company that is a Taxable Person must file a return for every Tax Period even if it:

• made an accounting loss or a Tax Loss;
• had no revenue or no taxable income;
• remained entirely within the 0% taxable-income band;
• had no Corporate Tax payable;
• was inactive or dormant but remained a Taxable Person;
• ceased trading during the period but had not completed its final obligations and deregistration; or
• elected for Small Business Relief.

The return reports the company’s financial and tax position, including any Tax Loss. A qualifying Tax Loss may be valuable in later periods, but it must be calculated, reported and supported correctly.

Read our detailed guide to UAE Corporate Tax Losses and carry-forward rules.

What Should Be Prepared Before Filing?

The return should be the final step of a controlled accounting and tax process, not the first time the company reviews its records. Before opening the form, the business should prepare or confirm the following:

• Complete accounting records for the full Tax Period.
• A reconciled trial balance and general ledger.
• Financial statements prepared using the applicable accounting standards.
• Revenue and expense schedules, including non-deductible or partly deductible items.
• Fixed-asset, depreciation and disposal schedules.
• Bank reconciliations and financing or interest schedules.
• Related-party and Connected Person information.
• Details of exempt income, foreign income and foreign tax credits, where relevant.
• Tax Loss schedules and any group-relief claims or transfers.
• Supporting documents for elections, exemptions and reliefs.
• The accounting-to-tax reconciliation and final Corporate Tax calculation.

The detailed accounting requirements are covered in our guide to Corporate Tax records and audited financial statements.

What Information Is Included in the Return?

The EmaraTax return is tailored to the Taxable Person’s profile and answers. The number and type of sections can differ according to factors such as the person’s category, revenue, Free Zone position and elections.

Depending on the person, the form may request information concerning:

• Taxable Person and Tax Period details.
• Financial and accounting information.
• Revenue and accounting profit or loss.
• Tax adjustments used to arrive at taxable income.
• Exempt income and reliefs.
• Free Zone status and Qualifying Free Zone Person elections or confirmations.
• Related parties and Connected Persons.
• Tax Losses, group relief and loss transfers.
• Foreign tax credits and other tax credits.
• Small Business Relief, where elected.
• The final Corporate Tax payable or refundable position.
• Declarations by the authorised signatory.

How to File Through EmaraTax

1. Log in to EmaraTax and open the correct Taxable Person profile.
2. Open the Corporate Tax dashboard and select the return for the relevant Tax Period.
3. Select “File” and read the instructions and guidelines.
4. Confirm the pre-populated Taxable Person, address and filing-period information.
5. If registration information is incorrect, initiate the appropriate registration amendment rather than overriding the discrepancy informally.
6. Complete every relevant return section and mandatory field.
7. Upload or retain the supporting information required for the person’s return and profile.
8. Review the completed return, calculations and elections carefully.
9. Complete the declaration and submit the return.
10. Save the submission acknowledgement and reference number.

The return can be saved as a draft and completed later, but a draft is not a filed return. The taxpayer should allow time for review, internal approval and the resolution of system or data issues before the deadline.

Who Can Submit the Return?

The Taxable Person may file directly through EmaraTax. An appropriately authorised individual may also act on its behalf, including a registered Tax Agent or legal representative within the scope of their authority.

Using an adviser does not transfer responsibility for inaccurate information away from the Taxable Person. Management should review the final figures, elections, declarations and payment position before submission.

How Is Corporate Tax Paid?

After the return is submitted, the liability appears in the Corporate Tax payment area of EmaraTax. The person can pay the liability in full or make partial payments before the due date, but the entire amount must be received and allocated by the deadline.

Payment methods available through EmaraTax include payment through the person’s Generated International Bank Account Number (GIBAN), using the payment reference generated after selecting the relevant liabilities, and online card payment through the payment gateway shown in EmaraTax. The exact platform instructions should be followed at the time of payment.

For a GIBAN payment through a UAE financial institution, the person should generate the unique payment reference number in EmaraTax and quote the GIBAN, reference number and exact amount. Incorrect or incomplete details can cause rejection or incorrect allocation.

The payment acknowledgement and transaction history should be retained with the Corporate Tax working papers.

What If the Registration Details Are Wrong?

The return uses information from the Corporate Tax registration profile. If the legal name, address, Financial Year, Free Zone position or other registered information is incorrect, the taxpayer may be prompted to submit a registration amendment before continuing.

Do not force the return to fit incorrect registration data. The underlying record should be corrected through the appropriate EmaraTax process, with supporting documents where required.

What If an Error Is Found After Filing?

The error should be reviewed promptly. The correct remedy depends on the nature of the error, whether Corporate Tax was understated or overstated, whether an FTA Tax Assessment has been issued and the correction mechanisms available under the Tax Procedures Law, the Corporate Tax Law and current FTA guidance.

A taxpayer should not assume that every error can simply be changed in the next return. Some errors may require a Voluntary Disclosure or another formal correction. The FTA also issued a public clarification in July 2026 concerning specific downward adjustments that a Taxable Person may make in a Tax Return to comply with the Corporate Tax Law. The facts and the latest guidance should be reviewed before selecting the correction method.

What Are the Consequences of Filing or Paying Late?

Late return filing

Failure to submit the Corporate Tax Return within the required period is subject to an administrative 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 onward.

Late payment

A separate penalty applies to unpaid Corporate Tax. It is calculated monthly at an annual rate of 14% on the unpaid amount, for each month or part of a month, beginning from the day following the payment due date and on the same date monthly thereafter.

Filing the return does not stop the late-payment penalty if the tax remains unpaid, and paying an estimated amount does not remove the late-filing penalty if the return has not been submitted.

Common Filing Mistakes

• Assuming that a loss-making or inactive company does not need to file.
• Using revenue as taxable income without preparing the accounting-to-tax reconciliation.
• Starting the return before the accounting records and bank reconciliations are complete.
• Selecting Small Business Relief without assessing its effect on Tax Losses and interest expenditure.
• Assuming that all Free Zone income qualifies for the 0% rate.
• Omitting related-party or Connected Person information.
• Using an incorrect Tax Period or Financial Year.
• Submitting without checking the pre-populated registration information.
• Leaving the payment instruction until the final day.
• Treating a saved draft as a filed return.
• Failing to save the submission and payment acknowledgements.
• Attempting to correct a filed error without first identifying the legally appropriate correction route.

Frequently Asked Questions

Must a company file if it made a loss?

Yes. A company that is a Taxable Person must file for every Tax Period even if it made a loss or has no Corporate Tax payable.

Must an inactive company file?

If the company remains a Taxable Person for the period and has not completed the relevant final obligations and deregistration, it must file. Inactivity does not by itself cancel the obligation.

Do the return and tax payment have to be made at the same time?

No. They may be completed separately, but both must be completed by their applicable deadline.

Can Corporate Tax be paid in instalments?

EmaraTax permits partial payments before the payment due date. The full Corporate Tax payable must nevertheless be received and allocated by the deadline.

Does electing for Small Business Relief remove the filing requirement?

No. The election is made through the Corporate Tax Return. Read our detailed guide to UAE Small Business Relief before making the election.

Can the company file without audited financial statements?

That depends on whether the company is legally required to prepare and maintain audited financial statements. Every company still needs reliable financial information supporting the return. Review our guide to Corporate Tax records and audited financial statements.

What should the company do if the deadline has passed?

File the return and pay the outstanding tax immediately, confirm the penalties recorded in EmaraTax and obtain advice on any correction, disclosure or dispute procedure that may be relevant. Further delay increases the exposure.
