Corporate tax filing is a mandatory requirement for businesses operating in the UAE. Companies must accurately report their taxable income and submit filings to the Federal Tax Authority (FTA) within the prescribed deadlines. Errors, delays, or incorrect reporting can lead to penalties and compliance risks.
At Corporate Tax UAE, we assist businesses in preparing and filing corporate tax filings accurately and on time, ensuring full compliance with UAE tax regulations. Corporate tax applies to:
- Mainland companies operating in the UAE
- Qualifying Free Zone Persons (QFZPs)
- Foreign entities with a permanent establishment in the UAE
Key Requirements for Corporate Tax Filing
- Corporate tax filings must be filed within 9 months from the end of the financial year
- Accurate financial records and supporting documentation are essential
- Proper classification of income and expenses is required for compliance

Who needs to File Corporate Tax Filing?
Any business registered and operating in the UAE is required to file a corporate tax filing, regardless of size or income level.
This includes:
- Mainland businesses across all industries
- Free zone entities, including those eligible for 0% corporate tax
- Foreign companies with operations or branches in the UAE
Even if a business falls below the taxable income threshold, filing is still required to maintain compliance with UAE tax regulations.

When is the Deadline for Corporate Tax Filing?
Corporate tax filing deadlines are based on your company’s financial year. Businesses must submit their corporate tax filing within 9 months from the end of their tax period.
For example:
- If your financial year ended on 31 December 2025, your corporate tax must be filed by 30 September 2026.
- If your financial year ends on 31 March 2026, your filing deadline will be 31 December 2026.
These are enforceable deadlines. Not meeting them could result in penalties. With our Corporate Tax Filing in the UAE assistance, you can be certain to file on time, every time.
