There are numerous businesses in the United Arab Emirates that are facing a significant deadline regarding the filing of corporate taxes. The professionals have advised various businesses to file their taxes ahead of the deadline in order to avoid any financial complications or penalties. Any business whose first tax period will end on December 31, 2025, should ensure that they file their corporate tax return and pay any liabilities owed by September 30, 2026, according to the requirements of the FTA.
This deadline represents one of the major deadlines faced by numerous organisations since the introduction of the UAE’s federal corporate tax system. According to experts, most businesses are now completing their first year of filing, which means that they need to ensure that their financial documents are completed and filed.

According to tax specialists, businesses should not assume that registration alone satisfies their obligations. Companies are required to file their corporate tax returns electronically through the FTA’s EmaraTax platform within nine months of the end of their financial year. Missing the filing or payment deadline could expose businesses to administrative penalties and additional compliance risks.
The UAE’s Corporate Tax framework applies a 0% tax rate on taxable income up to AED 375,000, while profits exceeding that threshold are generally taxed at 9%, subject to applicable exemptions and relief measures. Businesses eligible for Small Business Relief must still register and submit the required tax return to maintain compliance with FTA regulations.
Advisers are encouraging companies to use the remaining weeks before the September deadline to reconcile their financial records, verify eligibility for tax reliefs and seek professional guidance where necessary. They note that businesses operating across multiple jurisdictions or free zones may require additional review to ensure their tax positions align with UAE regulations.
The reminder comes as the FTA continues efforts to strengthen tax compliance following the rollout of the Corporate Tax regime. With the first major filing deadline now drawing closer, businesses are being urged to act early rather than wait until the final days, reducing the risk of processing delays and potential penalties.
