What is the corporate tax registration deadline in the UAE?
The corporate tax registration deadline in the UAE does not fall on a single date. The Federal Tax Authority published a staggered schedule based on the month shown on your trade licence. Businesses that were already licensed and operating when UAE CT came into effect on 1 June 2023 faced deadlines running from March to June 2024 for most. New businesses incorporated after that must register within three months of the date on their licence.
The practical upshot: if you set up a freezone company in, say, DMCC in October, your clock starts from that licence date. If you set up in IFZA or RAKEZ, same rule applies. The FTA does not write to you to remind you. You are expected to know.
Where to find your specific deadline
Log into the EmaraTax portal. If you are already registered for VAT, the system will prompt you to add the CT registration. If you are not VAT-registered, you create a CT-only profile. The portal will reflect the relevant deadline based on your licence data. If your licence has lapsed or been renewed to a different date, that can shift things, which is one reason to keep licence renewals clean.
What penalties apply for missing the CT registration deadline?
A fixed administrative penalty of AED 10,000 is issued automatically for late CT registration. There is no grace period, no warning letter, and no discretion at the point of imposition. It is one of the more mechanical parts of the UAE tax system.
Late filing of the tax return is a separate matter with a different penalty structure. The FTA charges AED 500 per month for the first year a return is outstanding, rising to AED 1,000 per month thereafter. Underpayment of tax itself attracts a percentage-based penalty on the unpaid amount.
These are not the kind of numbers that sink a business, but they add up quickly if registration, filing and payment deadlines are each missed in the same year.
What does the CT filing and payment timeline look like?
| Financial year-end | CT return filing deadline | Tax payment deadline |
|---|---|---|
| 31 December | 30 September (following year) | 30 September (following year) |
| 31 March | 31 December (same calendar year) | 31 December (same calendar year) |
| 31 May | 28 February (following year) | 28 February (following year) |
| 31 July | 30 April (following year) | 30 April (following year) |
The nine-month rule is fixed by the Corporate Tax Law. Filing and payment fall on the same date, you cannot file and pay separately. Businesses that have opted into a non-calendar financial year (which some freezones allow) need to map this out carefully.
Does this apply to freezone companies?
Yes. A common misread is that freezone companies are outside the CT system. They are not. Every UAE entity must register, file a return and pay tax if liable. The question of whether a freezone company is a Qualifying Free Zone Person, and therefore eligible for the 0% rate on qualifying income, is decided through the return, not by opting out of filing altogether.
In practice, the founders we work with in DMCC, IFZA, Meydan and RAKEZ are often surprised by this. The 0% headline is accurate for qualifying income, but getting to that position requires proper registration, a clean return and a defensible substance position. That work does not happen automatically.
The deadlines most founders miss
Registration is the one that catches people. The filing deadline is nine months away; it feels distant. The registration deadline, especially for newer businesses, sits much closer to incorporation.
A second common gap: businesses that change their financial year-end after registering. The nine-month clock recalculates from the new year-end, but the FTA needs to be notified of the change formally. Missing that step creates a mismatch between what you think your deadline is and what the portal actually shows.
A third: businesses that let their trade licence lapse before registering. A lapsed licence can complicate the EmaraTax process and, in some cases, trigger questions about the entity’s status for CT purposes.
If you want to understand how CT registration fits into the broader picture of setting up a compliant UAE company, the UAE corporate tax guide covers the full framework. For the entity type question that feeds into all of this, see choosing the right UAE company structure.
Getting the sequence right, licence, registration, substance, filing, is the thing worth doing properly from the start.
