Introduction
The UAE Corporate Tax filing season is now entering an important period for businesses with a 31 December financial year-end. Under the UAE Corporate Tax rules, a Taxable Person must generally submit its Corporate Tax Return and settle any Corporate Tax Payable within nine months from the end of the relevant Tax Period.
For a company whose Tax Period ended on 31 December 2025, the ordinary filing and payment deadline is 30 September 2026. That makes the remaining weeks critical for completing the accounts, reviewing tax adjustments, checking supporting schedules and submitting the return through EmaraTax on time.
الملخص بالعربية
إذا كانت السنة المالية للشركة قد انتهت في 31 ديسمبر 2025، فإن الموعد المعتاد لتقديم إقرار ضريبة الشركات وسداد الضريبة المستحقة هو 30 سبتمبر 2026. التأخر في تقديم الإقرار قد يؤدي إلى غرامة قدرها 500 درهم عن كل شهر أو جزء منه خلال أول 12 شهرًا، ثم 1,000 درهم عن كل شهر أو جزء منه بعد ذلك.
كما أن غرامة التأخر في التسجيل لضريبة الشركات هي 10,000 درهم، ويوجد برنامج إعفاء منفصل بشروط محددة يتطلب تقديم أول إقرار خلال سبعة أشهر من نهاية الفترة الضريبية الأولى.
1. What Is the UAE Corporate Tax Filing Deadline?
The general rule is simple: the Corporate Tax Return and the Corporate Tax Payable are due within nine months from the end of the Tax Period. The same nine-month principle applies to the annual declaration of an Exempt Person that is required to register, subject to the applicable rules.
| Tax Period end | 31 December 2025 |
| Ordinary filing deadline | 30 September 2026 |
| What is due | Corporate Tax Return + Corporate Tax Payable |
Businesses with a different financial year-end should calculate the deadline by reference to their own Tax Period and verify the exact date shown in EmaraTax, especially where there has been a short or long Tax Period, a change of financial year, a tax group event or another special circumstance.
2. Why 30 September 2026 Matters Now
For calendar-year businesses, 30 September 2026 is not only a filing date. It is also the date by which the tax computation, supporting records and payment position should be finalised. Waiting until the last few days creates avoidable risks: incomplete reconciliations, missed tax adjustments, incorrect elections, EmaraTax access issues, bank payment delays and late filing penalties.
A practical filing plan should therefore work backwards from the deadline. Management accounts and bank reconciliations should be completed first, followed by a tax review, management approval, return preparation, final quality control and submission.
3. Late Filing Penalty for a Corporate Tax Return
Cabinet Decision No. 75 of 2023, as amended, contains the Corporate Tax administrative penalty schedule. Failure to submit a Corporate Tax Return within the required timeframe results in:
- AED 500 for each month, or part thereof, for the first twelve months.
- AED 1,000 for each month, or part thereof, from the thirteenth month onwards.
The penalty begins after the filing deadline and is imposed monthly thereafter. A short delay can therefore still count as a month or part of a month for penalty purposes.
4. Late Payment Penalty
Failure to settle Corporate Tax Payable on time can also trigger a separate penalty. The Corporate Tax penalty schedule applies a monthly penalty at an annual rate of 14% on the unsettled Corporate Tax amount for each month or part thereof, starting from the day following the payment due date and on the same date monthly thereafter.
This is one reason filing and payment should be planned together. Submitting the return without arranging the tax payment does not eliminate the late-payment exposure.
5. AED 10,000 Late Registration Penalty and the Special Waiver
Late Corporate Tax registration carries an administrative penalty of AED 10,000. The Federal Tax Authority has, however, introduced a separate late-registration penalty waiver initiative.
To qualify, a Taxable Person must submit its first Corporate Tax Return within seven months from the end of its first Tax Period. An Exempt Person required to register must submit the annual declaration within seven months from the end of its first Financial Year. The initiative can apply to persons who registered late, have not yet registered, or have already been charged the penalty, whether paid or unpaid.
Important current point: for a business whose first Tax Period ended on 31 December 2025, seven months ended on 31 July 2026. That date is earlier than the ordinary nine-month Corporate Tax filing deadline of 30 September 2026. Businesses should therefore distinguish clearly between the ordinary filing deadline and the special waiver condition.
6. What Should Be Ready Before You File?
Before preparing the return, the accounting and tax file should be complete enough to support the figures submitted. At a minimum, review:
- Final trial balance and financial statements for the Tax Period.
- Bank reconciliations and year-end cash/bank balances.
- Sales and revenue reconciliation to accounting records and VAT returns where relevant.
- Cost of sales, operating expenses and supporting invoices.
- Fixed assets, depreciation and disposals.
- Related Party and Connected Person transactions, where applicable.
- Non-deductible or restricted expenses and any tax-specific adjustments.
- Tax losses, exemptions, elections or reliefs claimed, where applicable.
- Free Zone status and Qualifying Free Zone Person considerations, if relevant.
- Transfer Pricing disclosures and supporting documentation, where required.
- Supporting schedules for unusual, large or judgmental transactions.
7. Corporate Tax Filing Checklist
- Confirm the exact Tax Period and filing deadline in EmaraTax.
- Finalise the accounting records and complete all bank reconciliations.
- Reconcile revenue and major expense categories to supporting records.
- Review deductible, non-deductible and restricted expenses.
- Review Related Party and Connected Person transactions.
- Check Corporate Tax elections, reliefs and carried-forward balances.
- Prepare the Corporate Tax computation and reconcile it to accounting profit.
- Review the draft Corporate Tax Return against the computation and financial statements.
- Obtain management approval and arrange the Corporate Tax payment.
- Submit the return before the deadline and retain the filing acknowledgement and working papers.
8. Common Filing Errors to Avoid
- Using VAT turnover as a substitute for accounting revenue without reconciliation.
- Treating owner transfers, loans or internal bank movements as business revenue.
- Claiming expenses without adequate supporting documentation.
- Ignoring Related Party or Connected Person rules.
- Filing before the year-end accounts and bank balances are properly reconciled.
- Applying a relief or exemption without checking all eligibility conditions.
- Leaving the return until the final days and encountering EmaraTax or payment delays.
- Assuming that a nil tax liability means no Corporate Tax Return is required.
9. Should You File Early?
Where the accounting records are complete, early filing is generally preferable to last-minute filing. It gives management time to resolve tax questions, obtain missing supporting documents, correct bookkeeping issues and arrange payment. It also reduces the operational risk of missing the deadline because of portal access, internal approval or banking delays.
Early filing does not mean rushed filing. The objective is to submit a complete, supportable return after the financial statements and tax computation have been properly reviewed.

Frequently Asked Questions
What is the Corporate Tax filing deadline for a company with a 31 December 2025 year-end?
The ordinary Corporate Tax filing and payment deadline is 30 September 2026, being nine months after the end of the Tax Period.
What happens if the Corporate Tax Return is filed late?
The administrative penalty is AED 500 for each month or part thereof for the first twelve months, then AED 1,000 for each month or part thereof from the thirteenth month onwards.
What happens if the Corporate Tax is paid late?
A monthly penalty at an annual rate of 14% can apply to the unsettled Corporate Tax amount for each month or part thereof after the payment due date.
Can the AED 10,000 late-registration penalty still be waived?
Potentially, but the waiver is subject to the FTA initiative conditions. The key condition is submission of the first Corporate Tax Return within seven months from the end of the first Tax Period (or the annual declaration within seven months for an Exempt Person required to register).
Do I still need to file if no Corporate Tax is payable?
A nil tax liability does not by itself remove the filing obligation. A Taxable Person that is required to file must still submit the Corporate Tax Return within the applicable deadline.
