Corporate Tax registration deadlines are tied to your licence issue date or incorporation date, not the calendar year — and missing one carries an automatic AED 10,000 penalty. Here's exactly how the timelines work, and how to fix it if you're already late.
One of the most common Corporate Tax questions we hear from UAE business owners isn't about the 9% rate — it's about when they were actually supposed to register. Unlike VAT, which is threshold-triggered, Corporate Tax registration is mandatory for every taxable person regardless of revenue, and the deadline itself is tied to your trade licence issue date or incorporation date under FTA Decision No. 3 of 2024 — which means two businesses formed a month apart can face very different registration windows.
The Two Rulebooks: Before and After 1 March 2024
FTA Decision No. 3 of 2024 splits businesses into two groups. If your licence was issued before 1 March 2024, your registration deadline follows a fixed schedule set by your licence's issuance month — running from 31 May 2024 through 31 December 2024, regardless of what year the licence was originally issued. If your business was incorporated, established or otherwise recognized on or after 1 March 2024, you instead get a rolling window measured from that date: 3 months for a resident juridical person (commonly referred to as the 90-day rule, though it is legally a 3-calendar-month window), 6 months for a non-resident entity with a UAE Permanent Establishment, and 3 months for a non-resident entity with a UAE nexus but no PE. Resident natural persons (individuals in business) with turnover above AED 1 million in a calendar year have until 31 March of the following year.
A mainland trading company had its licence originally issued in July 2019. Under the fixed schedule in FTA Decision No. 3 of 2024, a July-issued licence falls into the '30 September 2024' deadline bracket — so this business needed to register by 30 September 2024, even though the licence itself was five years old and had nothing to do with 2024. A second company, incorporated fresh on 15 April 2024, instead counts 3 calendar months from that date and had until 15 July 2024 to register.
The Cost of Missing It: AED 10,000, No Exceptions
Cabinet Decision No. 75 of 2023, as amended by Cabinet Decision No. 10 of 2024, sets a flat AED 10,000 administrative penalty for late Corporate Tax registration. It is not scaled to your revenue, your profit, or how many days late you were — one day late and 200 days late both attract the same AED 10,000 charge. Crucially, the penalty applies even if your business ultimately owes zero Corporate Tax, for example because it qualifies for Small Business Relief or the 0% rate on the first AED 375,000 of profit. Registration is a standalone legal duty, separate from whether you owe tax.
- The AED 10,000 penalty is fixed — it does not increase the longer you remain unregistered, but interest and compounding exposure grow the longer other obligations (like return filing) are also missed
- The penalty applies even if your business had no taxable profit for the period
- Late registration doesn't remove the obligation to register — you must still complete registration immediately, and the return-filing clock keeps running from your actual tax period
- Repeated non-compliance can affect your standing in future FTA interactions, including audits, clarification requests and tax agent representation
If You've Already Missed It: The Penalty Waiver Initiative
Since 7 May 2025, the FTA has operated a penalty waiver initiative under Public Clarification CTP006 that can exempt or refund the AED 10,000 penalty entirely. It covers three situations: you registered late and haven't paid the penalty yet; you registered late and already paid it (in which case it's refunded); or you haven't registered at all yet. In every case, the condition is the same — you must file your first Corporate Tax return (or annual declaration) within 7 months of the end of your first tax period. This is a genuinely significant concession, but it is strictly time-bound: the sooner you act, the more likely your first tax period's 7-month window is still open.
- Registered late, penalty unpaid → file your first return within 7 months of your first tax period's end and the AED 10,000 charge is waived
- Registered late, penalty already paid → same 7-month filing window triggers an automatic refund, no separate application needed
- Not registered at all → register and file your first return together, both within the 7-month window, to qualify
How Corcess Helps
As an FTA-approved tax agency (TAN 30011993), we track registration and filing deadlines for every client on our books, so a missed date simply doesn't happen going forward. If you're not yet registered, or you're not sure whether you're still inside the CTP006 waiver window, that is the first thing we check on a free consultation call — because the difference between acting this month and acting next quarter can be the full AED 10,000.
