Missed the 30 September Corporate Tax Deadline? What to Do Now

Missed the 30 September Corporate Tax Deadline? What to Do Now

October 08, 2026•1 min read

For businesses with a financial year ending 31 December 2025, the Corporate Tax return and any tax due were due by 30 September 2026.

Late-filing penalties

Penalties for filing the return late build up every month:

  • AED 500 per month (or part of a month) for the first 12 months
  • AED 1,000 per month from the 13th month

Late payment of tax due also carries separate penalties.

What to do now

  1. File as soon as possible. Every month adds to the penalty.
  2. Gather your records: financial statements, trial balance, bank statements and invoices.
  3. Check your reliefs, such as Small Business Relief, which must be elected in the return.
  4. Pay any tax due to stop late-payment penalties growing.

Not registered yet?

If you should have registered and did not, registration comes first, then the return. We can handle both quickly.
