“Is my corporate tax return due this September?” If your business is approaching its filing deadline, September 2026 is an important month to watch. The 30 September 2026 deadline applies to relevant taxpayers whose tax period ended on 31 December 2025.
However, the exact deadline depends on the tax period, with the general rule requiring filing within 9 months from its end. This article explains the current corporate tax return scenario of the United Arab Emirates. You will also know about the UAE Corporate Tax Return deadline, who needs to file, how to avoid late-filing penalties, and key requirements.
Is Your UAE Corporate Tax Return Due on 30 September 2026?
Taxable persons whose “financial years ended on 31 December 2025” must file their UAE Corporate Tax return and pay their corporate tax by 30 September 2026. This date follows the broader rule that taxable persons generally have 9 months from the end of their relevant tax period to file their returns and settle their corporate tax obligations.

Certain exempt activities or persons may have different obligations.
