UAE Corporate Tax Filing Deadline: Who Must File & When?
If your business is subject to UAE Corporate Tax, one deadline matters more than most: your Corporate Tax Return is generally due within 9 months from the end of your Tax Period.
For example, if your Tax Period ends on 31 December, your Corporate Tax Return and any Corporate Tax payable are generally due by 30 September of the following year.
If your financial year ends on 31 March, the deadline would generally be 31 December.
The important point is that there is no single Corporate Tax filing date for every UAE business. Your deadline depends on your Tax Period.
The Federal Tax Authority (FTA) requires Taxable Persons to submit their Corporate Tax Returns and settle Corporate Tax payable within the prescribed timeframe.
And whether you operate from the UAE mainland, a Free Zone, or through a UAE Permanent Establishment, understanding your filing obligation is essential.
What Is the UAE Corporate Tax Filing Deadline?
The general UAE Corporate Tax filing rule is simple:
A Corporate Tax Return must generally be submitted within 9 months from the end of the relevant Tax Period.
The same deadline generally applies to payment of Corporate Tax due for that Tax Period.
| Tax Period / Financial Year | General Filing Deadline |
|---|---|
| 1 June 2024 – 31 May 2025 | 28 February 2026 |
| 1 January 2025 – 31 December 2025 | 30 September 2026 |
| 1 April 2025 – 31 March 2026 | 31 December 2026 |
The dates above demonstrate how the deadline changes depending on the company’s financial year-end.
Your business does not automatically have a September deadline simply because Corporate Tax exists in the UAE.
The relevant date is the end of your Tax Period.
Important
The filing and payment obligations should not be confused with the Corporate Tax registration deadline. Registration is a separate compliance requirement and must be completed according to the applicable registration timeline.
Who Must File a UAE Corporate Tax Return?
Corporate Tax applies broadly to UAE businesses, although certain persons and activities may be exempt or subject to specific rules.
The following categories are particularly important.
1. UAE Mainland Companies
UAE companies and other juridical persons incorporated or effectively managed and controlled in the UAE are generally within the scope of Corporate Tax.
This includes many:
- Limited liability companies
- Civil companies
- Private and public companies
- Other UAE juridical persons
Being a small company does not automatically mean you are outside Corporate Tax.
Your Corporate Tax position depends on the applicable legislation and your circumstances.
2. Free Zone Companies
One of the most common misconceptions is:
“My company is in a Free Zone, so I don’t need to file Corporate Tax.”
That is not correct.
Free Zone Persons are within the UAE Corporate Tax regime and are required to comply with the applicable Corporate Tax requirements.
A Free Zone Person that satisfies the conditions to qualify as a Qualifying Free Zone Person (QFZP) may benefit from a 0% Corporate Tax rate on Qualifying Income.
However, the 0% rate does not mean that the company can simply ignore Corporate Tax compliance or filing requirements.
Your Free Zone status, activities, income and compliance position all need to be considered when preparing the return.
3. Foreign Companies With a UAE Permanent Establishment
A foreign legal entity may also fall within the UAE Corporate Tax regime.
For example, a non-resident juridical person may be subject to UAE Corporate Tax where it has a Permanent Establishment in the UAE.
Therefore, having a foreign-incorporated company does not automatically eliminate UAE Corporate Tax obligations.
The exact tax position depends on the nature of the UAE presence and the applicable rules.
4. Individuals Conducting Business in the UAE
Corporate Tax can also apply to natural persons conducting a business or business activity in the UAE.
For individuals, the rules are different from those applying to companies.
Registration threshold
A natural person is generally required to register for Corporate Tax where the total revenue from conducting business or business activities exceeds AED 1 million in a calendar year.
Certain types of personal income, such as salary, private investment income and certain real estate investment income, are excluded when determining this threshold.
This means that simply earning more than AED 1 million personally does not automatically mean you have a Corporate Tax registration obligation.
The source and nature of the income matter.
Corporate Tax Registration vs Corporate Tax Filing
These are two different obligations.
Corporate Tax Registration
The business first needs to determine whether it is required to register for UAE Corporate Tax and, where applicable, obtain a Corporate Tax Registration Number.
Late registration can result in an administrative penalty of AED 10,000.
Corporate Tax Filing
After registration, the Taxable Person generally needs to submit a Corporate Tax Return for each Tax Period.
The standard filing deadline is generally:
9 months from the end of the Tax Period.
This distinction is important because registering for Corporate Tax does not mean your compliance is finished.
How Do You Calculate Your Corporate Tax Filing Deadline?
The easiest way is to start with your Tax Period end date.
Example 1: 31 December Year-End
| Suppose your Tax Period is | 1 January – 31 December |
| Your Tax Period ends on | 31 December |
| Add 9 months | 30 September |
| Your Corporate Tax Return and applicable payment are therefore generally due by | 30 September |
Example 2: 31 March Year-End
| Suppose your Tax Period is | 1 April – 31 March |
| Your Tax Period ends on | 31 March |
| Add 9 months | 31 December |
| Your deadline is therefore generally | 31 December |
Example 3: 31 May Year-End
| Suppose your Tax Period is | 1 June – 31 May |
| Your Tax Period ends on | 31 May |
| Nine months later | 28 February |
| Your deadline is therefore generally | 28 February |
This is why businesses should not rely on a generic “Corporate Tax deadline” without checking their own Tax Period.
What Happens If You Miss the Corporate Tax Filing Deadline?
Late filing can result in administrative penalties.
According to the FTA, failure to submit a Corporate Tax Return within the prescribed timeframe can result in:
| AED 500 | for each month, or part of a month, during the first 12 months |
| AED 1,000 | for each month, or part of a month, from the 13th month onwards |
There can also be separate consequences where Corporate Tax payable is not settled within the prescribed timeframe.
Late payment penalties are calculated under the applicable UAE tax legislation and can continue to accumulate on unpaid amounts.
The safest approach is simple: don’t wait until the deadline.
Does a Free Zone Company Have to File if Its Tax Rate Is 0%?
Generally, yes.
This is one of the most important points for Free Zone businesses.
A company may qualify for a 0% Corporate Tax rate on its Qualifying Income, but that does not mean the company can ignore the Corporate Tax system.
Free Zone Persons are within the Corporate Tax framework and must comply with the applicable registration and filing requirements.
The company should determine whether it qualifies as a QFZP and whether its income satisfies the applicable requirements.
What Is Small Business Relief?
Small Business Relief is designed to provide simplified Corporate Tax treatment for eligible smaller businesses.
Under the current rules, eligible resident Taxable Persons with revenue not exceeding AED 3 million for the relevant Tax Period may be able to claim Small Business Relief, subject to the applicable conditions.
The UAE Ministry of Finance has extended the availability of Small Business Relief to tax periods ending on or before 31 December 2029.
However, Small Business Relief is not automatically available to every business below AED 3 million in revenue.
Excluded from the relief
For example, the Ministry of Finance states that Qualifying Free Zone Persons and members of certain Multinational Enterprise Groups are excluded from the relief.
Therefore, businesses should assess eligibility before claiming the relief.
What Records Should You Keep for Corporate Tax?
Corporate Tax filing should not start with the EmaraTax form.
It should start with your accounting records.
Businesses should maintain appropriate:
| Accounting records | Sales and revenue records |
| Expense records | Bank statements |
| Invoices | Contracts |
| Payroll information | Fixed asset records |
| Related-party transaction records | Transfer pricing documentation, where applicable |
| Other supporting documents required under UAE tax legislation | |
The FTA has emphasised that Taxable Persons need to retain records and documentation supporting the information reported in their Tax Returns.
How to Prepare for Your Corporate Tax Filing
Don’t leave your Corporate Tax Return until the final few days.
Use this checklist.
|
Step 1: Confirm Your Tax Period Identify the exact beginning and ending dates of your Tax Period. |
|
Step 2: Calculate Your Filing Deadline Take the Tax Period end date and determine the applicable 9-month filing deadline. |
|
Step 3: Finalise Your Accounts Make sure your bookkeeping and accounting records are complete. |
|
Step 4: Review Tax Adjustments Accounting profit is not necessarily the same as taxable income. Review applicable adjustments, exempt income, deductible and non-deductible expenses and other Corporate Tax considerations. |
|
Step 5: Review Related-Party Transactions If your business has transactions with related parties or connected persons, review whether transfer pricing requirements apply. |
|
Step 6: Check Free Zone Status If you operate from a Free Zone, determine whether you qualify as a QFZP and whether your income and activities meet the relevant conditions. |
|
Step 7: Check Small Business Relief If your business has relatively low revenue, determine whether Small Business Relief is available before making the relevant election. |
|
Step 8: Prepare the Corporate Tax Return The return is submitted electronically through EmaraTax. The FTA confirms that Corporate Tax registration, return filing and payment services are available through EmaraTax. |
|
Step 9: Pay Any Corporate Tax Due If Corporate Tax is payable, ensure payment is completed within the applicable deadline. |
|
Step 10: Keep Supporting Documentation Keep the records supporting your Corporate Tax calculation and return. |
