When is your UAE Corporate Tax return due?
The deadline is not the same for every business. It generally depends on the end of the relevant Tax Period, making a reliable UAE corporate tax filing calendar essential for companies, Free Zone businesses and other taxable persons.
Under the UAE Corporate Tax Law, a Taxable Person generally must file its Corporate Tax Return and pay the tax due within nine months from the end of the relevant Tax Period, unless the FTA specifies otherwise.
Therefore, businesses should identify their Tax Period, registration requirements and applicable filing and payment deadlines rather than relying on one fixed annual date.
Let us break down how to build and maintain a Corporate Tax calendar that works for your UAE business.
A UAE Corporate Tax filing calendar is a structured schedule used to track the important Corporate Tax obligations of a business throughout its Tax Period.
It can include:
The Ministry of Finance recommends that businesses understand their Tax Period, registration requirements, filing deadline and record-keeping obligations as part of preparing for Corporate Tax.
A good calendar therefore does more than show one final filing date. It creates a compliance timeline from registration through return preparation, submission and payment.
The most important rule to remember is the nine-month rule.
Article 53 of Federal Decree-Law No. 47 of 2022 provides that a Taxable Person must file its Tax Return no later than nine months from the end of the relevant Tax Period, unless another date is directed by the FTA. Article 48 similarly provides that Corporate Tax payable must generally be settled within nine months from the end of the relevant Tax Period.
Example: 31 December year-end
Suppose a company has a Tax Period ending on 31 December. Its general filing and payment deadline would be:
31 December → nine months → 30 September
Therefore, a company whose relevant Tax Period ends on 31 December would generally need to submit its Corporate Tax Return and settle the Corporate Tax payable by 30 September of the following year.
The FTA has specifically reminded taxpayers that Corporate Tax Returns and Corporate Tax payable must generally be submitted and settled within nine months from the end of each Tax Period.
Example: 31 March year-end
If the Tax Period ends on 31 March, the nine-month deadline would generally fall on 31 December.
This illustrates why there is no single Corporate Tax filing date applicable to every UAE business.
The first step in preparing a UAE corporate tax filing calendar is therefore to identify the entity’s Tax Period.
| Tax Period end | General return and payment deadline |
| 31 January | 31 October |
| 28/29 February | 30 November |
| 31 March | 31 December |
| 30 April | 31 January |
| 31 May | 28/29 February |
| 30 June | 31 March |
| 31 July | 30 April |
| 31 August | 31 May |
| 30 September | 30 June |
| 31 October | 31 July |
| 30 November | 31 August |
| 31 December | 30 September |
These examples illustrate the general nine-month rule. Businesses should confirm the applicable Tax Period and deadline for their own circumstances rather than relying solely on a generic calendar. The Ministry of Finance also provides examples of registration, filing and payment deadlines based on different financial year-ends.
One of the biggest mistakes businesses make is treating Corporate Tax registration and Corporate Tax Return filing as the same obligation. They are not.
A business may have a Corporate Tax registration deadline that occurs before its first Corporate Tax Return deadline.
The FTA has issued specific registration timelines for different categories of Taxable Persons. For example, resident juridical persons incorporated or established in the UAE on or after 1 March 2024 generally have a registration application deadline of three months from incorporation, establishment or recognition. Different rules apply to certain non-resident persons, natural persons and other categories.
The FTA’s official registration service also explains the Corporate Tax registration process through EmaraTax.
Your compliance calendar should therefore contain at least two separate entries:
1. Corporate Tax registration deadline
and
2. Corporate Tax Return filing/payment deadline
This distinction is particularly important for newly established UAE businesses.
Waiting until the final month to prepare the Corporate Tax Return can create unnecessary pressure. A better approach is to work backwards from the filing deadline.
Start by confirming the company’s financial year and the corresponding Tax Period. Do not assume that every UAE company uses a calendar-year Tax Period.
Before preparing the Corporate Tax Return, the accounting records should be brought up to date. This includes:
Reliable accounting records make the tax calculation significantly easier to review.
The Corporate Tax calculation starts with reliable financial information. Businesses should therefore ensure that their financial statements and underlying accounting records are complete and properly supported.
Accounting profit is not automatically the same as taxable income. The Corporate Tax Return may require adjustments based on the UAE Corporate Tax rules.
The FTA’s Corporate Tax – Tax Returns Guide provides detailed guidance on completing the Corporate Tax Return and explains the information that may need to be provided in the return.
Businesses should organize the documents supporting their calculations before submission. Depending on the business, these may include:
A common misconception is that a Free Zone business can ignore Corporate Tax compliance because it may qualify for the Qualifying Free Zone Person regime.
That is not a safe assumption. Eligibility for a particular Corporate Tax treatment does not mean the business can simply ignore its Corporate Tax obligations.
Free Zone businesses should determine their status under the applicable Corporate Tax rules and maintain appropriate records to support their position.
The FTA’s Corporate Tax Return User Manual specifically includes a Free Zone Details section within the Corporate Tax Return process, demonstrating that Free Zone-related information can form part of the filing process.
Therefore, Free Zone companies should have their own Corporate Tax compliance calendar rather than assuming that normal filing obligations do not apply.
A practical Corporate Tax tracker can be maintained in Excel, accounting software or a compliance management system. A simple tracker could contain these columns:
| Item | Information to Track |
| Entity name | Legal entity |
| TRN | Corporate Tax Registration Number |
| Tax Period | Start and end date |
| Registration deadline | Applicable registration date |
| Return deadline | Nine-month deadline, where applicable |
| Payment deadline | Corporate Tax payment date |
| Accounting close | Internal deadline |
| Tax computation | Preparation status |
| Return review | Reviewer/sign-off |
| EmaraTax submission | Submitted/not submitted |
| Payment | Paid/not paid |
| Evidence | Acknowledgement/payment record |
For businesses managing multiple companies, this becomes particularly useful.
Instead of maintaining one reminder such as “Corporate Tax due”, finance teams can create a separate compliance record for every taxable entity.
The legal deadline should not be your internal deadline.
For example, if your Corporate Tax Return is due on 30 September, your internal calendar could look like this:
30 June: Accounting records substantially closed
↓
31 July: Financial statements prepared
↓
15 August: Tax computation completed
↓
31 August: Management review completed
↓
15 September: Final Corporate Tax Return review
↓
20 September: EmaraTax submission/payment preparation
↓
30 September: Statutory deadline
This gives the business a buffer for unexpected issues such as missing invoices, accounting errors, related-party information or questions arising during the tax review.
Corporate Tax Returns are filed electronically through the FTA’s systems. The FTA has published a dedicated Corporate Tax Return Taxpayer User Manual covering the filing process in EmaraTax. The manual walks taxpayers through areas including taxpayer details, Free Zone details, accounting schedules, adjustments, reliefs, tax liability, review and declaration, submission and payment.
For businesses preparing their first return, this is one of the most useful government documents to keep alongside the compliance calendar. The FTA also provides an official Corporate Tax Returns Guide, which explains the information and fields involved in completing a Corporate Tax Return.
Missing a Corporate Tax deadline can create financial and compliance consequences. The FTA has emphasized the importance of submitting Tax Returns and settling Corporate Tax payable within the prescribed deadlines to avoid late-payment penalties and other non-compliance consequences. This is why businesses should treat the filing date as the final legal deadline, not the date when preparation begins.
A strong process includes:
Businesses should rely primarily on the UAE Ministry of Finance and Federal Tax Authority for statutory information rather than generic online deadline lists.
The Ministry of Finance Corporate Tax page provides information about the UAE Corporate Tax regime, including the general nine-month filing and payment rule and guidance on determining a business’s Tax Period and obligations.
The FTA maintains an official library of Corporate Tax guides, references and public clarifications. This is particularly useful when a business needs guidance on a specific Corporate Tax issue rather than a general deadline.
For registration-related deadlines, use the FTA’s official registration timeline document rather than applying the nine-month filing rule to registration.
These official resources give businesses a direct route to the exact government information relevant to their obligation.
Keeping track of Corporate Tax deadlines becomes more complicated when a business has multiple entities, different financial year-ends, Free Zone considerations, or incomplete accounting records.

No. The general deadline is linked to the end of the relevant Tax Period. A Taxable Person generally has nine months from the end of its Tax Period to file its Corporate Tax Return and settle Corporate Tax payable.
No. Registration deadlines are governed by specific rules for different categories of Taxable Persons. They should be tracked separately from the Corporate Tax Return deadline.
Free Zone businesses should determine their Corporate Tax status and applicable obligations rather than assuming that Free Zone status removes filing requirements. The FTA’s Corporate Tax Return process includes specific Free Zone information.
The FTA publishes both a Corporate Tax Returns Guide and a Corporate Tax Return Taxpayer User Manual. These are the most useful official documents for understanding the return and its EmaraTax submission process.
No. It is better to set internal deadlines several weeks or months before the statutory due date. This gives the finance team time to close the accounts, resolve errors, complete the tax computation, and review the return.
A reliable UAE corporate tax filing calendar should do more than record one annual deadline. It should track the complete compliance process from Corporate Tax registration and Tax Period identification to accounting close, tax computation, return submission, and payment. The key rule is that a Taxable Person generally has nine months from the end of its relevant Tax Period to file its Corporate Tax Return and settle the Corporate Tax payable.
