UAE Corporate Tax Deadlines and Late Filing Penalties Clarified in Compliance Guidance

Under United Arab Emirates corporate tax regulations, taxable entities must submit their tax return and settle any tax payable within nine months following the conclusion of their financial year. For entities operating on a financial year that ended on December 31, 2025, the statutory deadline fell on September 30, 2026. The requirement applies uniformly without extensions for small businesses, free zone companies, or dormant entities.

According to an advisory published by Cressford Chartered Accountants, failure to file within the nine-month period triggers administrative penalties enforced by the Federal Tax Authority (FTA). Late filing incurs a fine of AED 500 per month or part of a month for the first 12 months, increasing to AED 1,000 per month from the thirteenth month onwards. Late tax payment incurs an annual charge of 14 percent applied monthly on outstanding tax liabilities, while failure to register for corporate tax on time carries an administrative penalty of AED 10,000.

Upcoming compliance milestones require entities with a financial year ending March 31, 2026, to file and pay by December 31, 2026. Businesses with years ending June 30, 2026, must complete submissions by March 31, 2027, and those closing December 31, 2026, face a deadline of September 30, 2027. Entities ceasing operations or entering liquidation are required to apply for corporate tax deregistration within three months of cessation.

Audited financial statements remain mandatory for businesses with revenues exceeding AED 50 million in a given tax period, as well as for all Qualifying Free Zone Persons seeking to retain the 0 percent corporate tax rate. In addition, resident entities with revenue of AED 3 million or less can elect for Small Business Relief to be treated as having no taxable income, though this relief applies only to tax periods ending on or before December 31, 2026, and must be explicitly claimed within the tax return.
