UAE Corporate Tax: the deadlines every firm should have on the wall

The date that catches firms out isn't the one they expect. Most people remember that corporate tax is 9% on profits above AED 375,000. Fewer keep a clean list of when each client actually has to act and that list is where the penalties hide.

Registration: the first date, and it's already passed for many

Every taxable person has to register for corporate tax on the FTA's EmaraTax portal and receive a Tax Registration Number. The FTA set staggered registration deadlines based on the month a licence was issued, and missing your window carries a fixed AED 10,000 penalty. If you took on a client who hasn't registered yet, treat it as urgent, not routine the penalty doesn't scale down for a small firm.

The 9-month rule that runs everything else

Here's the one to write large: a company's corporate tax return, and the payment, are due within nine months of the end of its financial year. A client with a December year-end files by the following September. A client on a June year-end files by March. Because your book has clients on different year-ends, you don't have one filing season you have a rolling one, and a spreadsheet sorted by client name won't show you what's due next.

What actually helps: a per-client obligation view

The firms that stay calm through this aren't working harder; they've stopped tracking deadlines by memory. Each client's year-end drives its own set of dates, and the moment one cycle closes the next one should appear. That's the difference between a list you maintain and a system that maintains itself. In AudiTax, a client's financial year is a field on their record, and the corporate tax obligation rolls forward on its own once a filing is marked done so "what's due in the next 30 days, across every client" is a screen, not an afternoon of cross-checking.
