UAE Corporate Tax returns and any Corporate Tax payable are generally due within nine months after the end of the relevant tax period. For example, a business with a financial year ending 31 December 2025 must file and pay by 30 September 2026. BCL Globiz is an FTA-registered corporate tax consultancy with 35+ years of experience and 300+ experts. It helps UAE businesses identify their correct tax period, prepare accurate returns, and meet Federal Tax Authority deadlines.
Quick answer: Your filing date is not based on one universal calendar deadline. It is calculated from the final day of your own tax period. Filing and payment normally share the same due date.
What Is the Main UAE Corporate Tax Deadline?
Under Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses, a Taxable Person must generally submit a Corporate Tax return no later than nine months from the end of the relevant tax period. Any Corporate Tax due for that period is generally payable by the same deadline.
The tax period usually follows the financial year used for the company’s financial statements. This means two UAE companies can have different filing dates even though both are subject to the same federal Corporate Tax regime. The decisive question is: on what date does the company’s tax period end?
The UAE Corporate Tax regime applies to financial years beginning on or after 1 June 2023. Returns and payments are handled through the FTA’s EmaraTax platform.
UAE Corporate Tax Deadline Examples
The following examples apply the standard nine-month rule. Businesses should confirm the tax period shown in EmaraTax because a special FTA decision, an approved change of tax period, or unusual first-period dates can alter the result.
| Tax period end | Standard return and payment deadline |
| 31 December 2025 | 30 September 2026 |
| 31 March 2026 | 31 December 2026 |
| 30 June 2026 | 31 March 2027 |
| 30 September 2026 | 30 June 2027 |
| 31 December 2026 | 30 September 2027 |
Deadline basis: UAE Ministry of Finance Corporate Tax guidance and Federal Tax Authority guidance.
Which Corporate Tax Deadlines Should UAE Businesses Track?
Corporate Tax Registration
Registration is separate from annual return filing. Taxable Persons must apply for Corporate Tax registration within the timeframes prescribed by FTA Decision No. 3 of 2024, as amended or replaced from time to time. The applicable date can depend on matters such as the month in which a juridical person’s licence was issued, the date of incorporation for certain entities, or when a non-resident meets the relevant conditions.
A business should not wait until its first return deadline to check registration. It should confirm its registration status and Corporate Tax Registration Number in EmaraTax as soon as the obligation arises.
Corporate Tax Return Filing
A separate return is generally required for each tax period. The standard due date is nine months after that period ends. A company with no tax payable may still have to file. A low level of income, an accounting loss, or a 0% rate does not automatically remove the filing obligation.
Payment of Corporate Tax
Corporate Tax payable is generally due by the return filing deadline. The FTA recommends paying early enough for the amount to reach the Authority before the final date. Bank and payment processing time can create a late payment issue even when a payment instruction is initiated on the last day.
Annual Declarations for Certain Exempt Persons
An Exempt Person that is required to register may need to submit an annual declaration within nine months after the end of its financial year. Exempt status should therefore not be treated as an automatic exemption from every administrative obligation.
Transfer Pricing Documentation
The Corporate Tax return may require a transfer pricing disclosure form where the relevant conditions are met. A taxable person that meets the prescribed thresholds for a master file and local file must maintain those records and submit them to the FTA within 30 days of a request, or within another period specified by the Authority. Businesses should complete related-party analysis before the return due date rather than begin it after an FTA request.
Do Free Zone Companies Have the Same Filing Deadline?
Yes. A Free Zone Person is within the scope of UAE Corporate Tax and generally must register and file a return. A Qualifying Free Zone Person may benefit from a 0% rate on Qualifying Income, but that treatment does not remove the normal registration, return filing, record keeping, and compliance obligations.
Free Zone businesses should also test the Qualifying Free Zone Person conditions, classify qualifying and non-qualifying income, review audited financial statement requirements where applicable, and document related-party dealings before their filing date.
Does Small Business Relief Remove the Filing Deadline?
No. An eligible Resident Person that wishes to claim Small Business Relief must make the election in its Corporate Tax return for the relevant period. The FTA has confirmed that a registrant with a financial year ending 31 December 2025 must submit its return by 30 September 2026, including where the registrant is eligible for Small Business Relief.
Relief from a Corporate Tax amount is not the same as relief from filing. The business must also retain appropriate records supporting its revenue and its eligibility.
What Happens If a Corporate Tax Deadline Is Missed?
The FTA states that late submission of a Corporate Tax return or delay in settling Corporate Tax payable can result in an administrative penalty of AED 500 for each month, or part of a month, during the first 12 months. From the thirteenth month onward, the amount increases to AED 1,000 for each month, or part of a month.
Other penalties can apply to late registration, inaccurate information, failure to maintain required records, or other breaches under the Tax Procedures Law and Corporate Tax legislation. The exact consequences depend on the breach and the legislation in force when it occurs.
If a deadline has already passed, the safer response is to review the EmaraTax account immediately, complete outstanding filings, arrange payment, and assess whether any correction, reconsideration, waiver initiative, or voluntary disclosure route is relevant. A business should not assume that inactivity will prevent further penalties.
How to Calculate and Manage Your Deadline?
Use this practical sequence to turn the legal rule into a controlled compliance process:
- Confirm the legal entity, Corporate Tax Registration Number, and registered tax period in EmaraTax.
- Identify the final day of the relevant tax period from the company records and FTA profile.
- Add nine calendar months to determine the standard filing and payment date.
- Check FTA decisions and official announcements for any special extension or change affecting that period.
- Set internal cut-off dates for bookkeeping closure, financial statements, tax adjustments, elections, transfer pricing review, and management approval.
- Prepare the return and payment several weeks before the legal deadline.
- Retain the submitted return, payment confirmation, financial statements, calculations, elections, and supporting records.
A Practical Corporate Tax Filing Timeline
Three to Six Months Before the Deadline
Close the accounting period, reconcile bank and ledger balances, finalise financial statements, review fixed assets and provisions, and identify transactions that may require Corporate Tax adjustments.
One to Three Months Before the Deadline
Calculate taxable income, assess exempt income and non-deductible expenditure, review interest limitation and loss positions, confirm elections or relief claims, and complete transfer pricing checks.
At Least Two Weeks Before the Deadline
Complete management review, validate the EmaraTax profile, submit the return, and arrange payment with sufficient processing time. Keep evidence of both submission and successful settlement.
Common Deadline Mistakes to Avoid
- Assuming every UAE company has a 30 September deadline.
- Confusing the registration deadline with the annual return deadline.
- Believing that no tax payable means no return is required.
- Treating a Free Zone 0% position as an exemption from filing.
- Forgetting that Small Business Relief must be elected through the return.
- Starting transfer pricing and related-party analysis after the return is prepared.
- Authorising payment on the final day without allowing processing time.
- Relying on an old calendar instead of checking the current EmaraTax tax period.

Final Takeaway
The key UAE Corporate Tax deadline is nine months after the end of the business’s tax period, not nine months after registration and not one fixed date for every company. Confirm the tax period in EmaraTax, calculate the date correctly, complete the return and payment early, and continue filing even where a relief, loss, Free Zone treatment, or 0% rate may apply.
