Your UAE company deadlines. One calendar.

Confirm it was filed. The return for the tax period ending 31 December 2025 was due 30 September 2026. If it was not filed, the late filing penalty is already AED 500 and grows each month (AED 500 a month in the first year, then AED 1,000). If the company was formed after 31 December 2025, this return does not apply; add the formation date.

If missed: AED 500 for each month or part of a month late during the first 12 months, then AED 1,000 a month. Late payment of tax is penalised separately. Source: Corporate tax return: overdue unless already filed (opens in a new tab)

UAE companies, including free zone companies, generally must register even if they pay 0%. Add the issue date of your first licence to see the deadline.

Suggested reminder: six months after the financial year ending 31 December 2025. Your free zone sets the actual deadline, which may be earlier, and whether audited accounts must be submitted to it; check its rules.

If missed: Your free zone sets any late fee; we do not list one. Qualifying Free Zone Persons, and companies with revenue over AED 50 million in the tax period, must prepare and keep audited financial statements for corporate tax (Ministerial Decision 84 of 2025).
