The UAE Corporate Tax return deadline of 30 September 2026 is approaching for businesses whose financial year ended on 31 December 2025. Companies falling within this filing cycle must submit their Corporate Tax return through EmaraTax and settle any Corporate Tax payable by the applicable deadline.
For businesses in Abu Dhabi and across the UAE, Corporate Tax compliance involves more than simply submitting a tax return. Businesses need to ensure that their financial statements, tax computations, related-party transactions, reliefs and, where applicable, Free Zone status are properly reviewed before filing.
Missing the deadline or submitting an inaccurate return can result in penalties and additional compliance requirements.
The UAE Corporate Tax return is generally due nine months after the end of the relevant tax period.
For businesses following different financial year-ends, the applicable deadlines can vary:
| Financial Year End | Corporate Tax Return & 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 |
Therefore, if your company’s financial year ended on 31 December 2025, 30 September 2026 is the key date to remember.
There is no general extension simply because a business requires additional time for ordinary commercial or administrative reasons. Businesses should therefore begin their preparation well before the deadline.

One of the common misconceptions surrounding UAE Corporate Tax is that businesses only need to file when Corporate Tax is payable.
A Corporate Tax return may still be required even where a business:
In other words, having no Corporate Tax payable does not automatically remove the filing obligation. A nil Corporate Tax return may still need to be submitted for the relevant tax period.
Corporate Tax filing should not be treated as a last-minute task. Businesses should ensure that the necessary financial and tax information is ready before submitting the return.
The Corporate Tax computation starts with the company’s accounting results.
Businesses should ensure their financial statements are finalised and properly prepared. The reference material notes that accrual-basis accounts should be prepared under IFRS, or IFRS for SMEs where the applicable revenue condition is met.
Any unresolved accounting issues can affect the subsequent Corporate Tax computation.
Accounting profit may need to be adjusted for Corporate Tax purposes.
Depending on the company’s circumstances, the computation may involve considerations such as:
Businesses should maintain supporting calculations and working papers for the positions reported in the return.
Businesses that have transactions with related parties or connected persons should review and properly document these transactions.
Where applicable, businesses may also need to consider:
A proper review before filing can help businesses identify potential issues before they become compliance problems.
Being established in a UAE Free Zone does not automatically mean that all income is subject to 0% Corporate Tax.
Businesses claiming Qualifying Free Zone Person status need to assess whether they meet the relevant conditions.
The review may include factors such as:
Free Zone businesses should therefore review their position carefully before submitting the Corporate Tax return.
Certain elections and reliefs can have an impact on a company’s Corporate Tax position.
Depending on the circumstances, businesses may need to consider matters such as:
Businesses should understand the implications of any election or relief before filing the return, particularly where the relevant choice cannot simply be changed later.
Late filing and late payment can result in financial penalties.
The reference material identifies the following consequences under the applicable penalty framework:
Beyond the financial cost, late or incorrect filings can create additional compliance work and may require businesses to correct their tax position later.
If your financial year ended on 31 December 2025, the following approach can help you prepare:
Verify the relevant Corporate Tax period and filing deadline.
Make sure your Corporate Tax registration, authorised signatory, contact information and licence details are current.
Complete the financial statements and resolve outstanding accounting matters.
Identify applicable adjustments, deductions, exemptions and reliefs.
Check disclosure and transfer pricing requirements where applicable.
If your business is claiming Qualifying Free Zone Person treatment, verify that the relevant requirements are satisfied.
An independent review can help identify errors or unsupported positions before filing.
Submit the Corporate Tax return through EmaraTax and settle any Corporate Tax payable by the applicable deadline.
