Accounting and Tax 
UAE corporate tax deadlines are firm: a date to register, and a date to file the return and pay any tax after the financial year ends. Missing registration or filing triggers penalties in its own right, even when no tax is due. Knowing the dates for your financial year, and acting ahead of them, keeps a company penalty-free.
When must a company register for corporate tax?
Under the Federal Tax Authority, a taxable person must register for corporate tax and obtain a registration number, with the deadline driven by the type of entity and its licence or incorporation timing. The authority has published specific registration deadlines, and late registration carries an administrative penalty regardless of whether any tax is owed. We confirm your registration deadline against the current rules and register you in good time rather than at the last minute.
When is the return due and the tax payable?
The corporate tax return must be filed, and any tax paid, within nine months of the end of the relevant tax period, which for most companies is the financial year. So a company with a calendar financial year ending 31 December files and pays by the following 30 September. There is a single deadline for both the return and the payment, which is why the books need to be ready well before it.
What are the penalties for missing a deadline?
The authority applies administrative penalties for late registration, late filing, late payment and for errors, set out in the penalties schedule. They accrue whether or not tax is ultimately due, which is why even a dormant or loss-making company cannot simply ignore the obligations. The cost of a missed deadline is almost always far more than the cost of filing on time, which is the whole case for staying ahead of it.
How do you stay ahead of the deadlines?
Register in good time, keep the books current through the year rather than scrambling at year end, and diarise the nine-month filing date from the financial year end. A business that treats corporate tax as a running obligation rather than an annual panic rarely incurs a penalty. We keep the books and the calendar for the companies we manage so nothing is missed.
What is the next step?
Tell us your financial year end and we will confirm your registration and filing deadlines and handle both. See our corporate tax and bookkeeping services and the Federal Tax Authority corporate tax guide. Every number here is checked against its source, such as the UAE Government free zones overview, before you rely on it, because published fees change.

Yes. Late registration carries an administrative penalty regardless of whether any tax is owed, so registering by your specific deadline matters even for a dormant company. -
