The UAE corporate tax deadlines you can't miss — registration and return filing — and the penalties for getting them wrong.

By Omega Global Editorial·Updated May 2026·5 min read

Registration deadline

All taxable persons must register for UAE corporate tax with the Federal Tax Authority by the deadline that applies to them. Registering late can trigger administrative penalties, so confirm your date early.

Filing & payment

Corporate tax returns are filed annually, generally within nine months of the end of the relevant tax period. Payment is due by the same deadline.

Common penalties

Penalties can apply for late registration, late filing, late payment and incorrect records. Amounts vary and add up — accurate books and a managed calendar are the best protection.

How to stay compliant

Register on time, keep IFRS-compliant records, reconcile regularly and file early. We manage registration, computation and filing so deadlines are never missed.
