The clock is ticking on UAE Corporate Tax.

If your financial year ended on 31 December 2025, your first Corporate Tax return is due by 30 September 2026, and that same date is also the deadline to pay any tax owed.

A few things every business owner should know:

→ You have 9 months from your financial year end to file your Corporate Tax return.

→ Filing is mandatory for all taxable persons, including Free Zone companies and businesses that qualify for a 0% tax rate or have no Corporate Tax payable.

→ Late filing penalties can start at AED 500 per month for the first 12 months, increasing to AED 1,000 per month thereafter, with 14% annual interest applying to unpaid tax balances.

A Free Zone company that misses its filing deadline may also risk losing access to preferential 0% tax treatment, so assuming "we don't owe any tax" is never a valid reason to delay filing.

Don't wait until September, get your books finalised, your figures reconciled, and your return submitted well before the deadline.
