All UAE taxable persons — companies, partnerships, and trade-licence individuals — must register for Corporate Tax on EmaraTax. The deadline is generally 3 months from the end of the first tax period. Late registration penalty: AED 10,000 (potentially waived if the first CT return is filed within 7 months of the financial year end). Registration takes 2–5 business days.
Who must register for UAE Corporate Tax?
Registration is mandatory for every UAE taxable person: all UAE-incorporated juridical persons (LLCs, PSCs, free zone companies, branches), individuals with a UAE trade licence conducting business, and foreign entities with a UAE permanent establishment. There is no revenue minimum — a newly incorporated company with zero revenue must register.
The only entities fully exempt from CT (and registration) are government entities (federal and emirate), government-controlled entities meeting the conditions, extractive businesses under specific emirate concessions, and certain non-extractive natural resource businesses.
Having a UAE VAT TRN does not automatically register you for Corporate Tax. CT registration is a separate process on EmaraTax. You will receive a separate CT tax registration number (TRN) after CT registration is approved. Many businesses discovered this when they received FTA reminders in 2023–24.
Registration deadlines
The broad registration grace period FTA granted in 2023–2024 has expired for most entities whose first CT period ended by 31 May 2024. If you have not yet registered, you are already in a late registration position — register immediately and consider a voluntary disclosure if a CT return has been missed.
| Entity type | Deadline |
|---|---|
| UAE companies — first CT period ending by 31 May 2024 | 28 February 2025 (extended deadline per FTA) |
| UAE companies — first CT period ending after 31 May 2024 | 3 months from end of first tax period |
| Natural persons (trade licence) | 31 March of the following Gregorian year |
| New businesses formed after 1 March 2024 | 3 months from date of incorporation/establishment |
| Foreign permanent establishments | Before the first UAE CT return is due |
Documents required for CT registration
- Trade licence — current and valid copy from the issuing authority (DED, free zone authority, etc.)
- Memorandum and Articles of Association — constitutional documents for the entity
- Emirates ID of authorised signatory — the person making the registration
- Passport copy of authorised signatory
- Financial year information — start date, end date of the entity’s first CT financial year
- Bank account details — for future CT refunds, if applicable
- Contact details — registered address, phone, and email for correspondence
EmaraTax CT registration — step by step
Log in to EmaraTax
Go to eservices.tax.gov.ae and log in using UAE Pass or email. If you do not have an EmaraTax account, create one — the portal serves both VAT and CT registrations under one login.
Start a new CT registration
From the EmaraTax dashboard, select ‘Register for Corporate Tax’. This is separate from VAT — the portal will prompt you to initiate a new registration, not link to your VAT profile.
Enter entity details
Input your trade licence number, entity type, financial year dates, and Emirates. EmaraTax pre-fills some details from the government registry. Verify and correct where needed.
Upload documents
Upload the required documents (trade licence, MoA, Emirates ID, passport). All documents must be in PDF or JPG format, clearly legible. File size limits apply — compress large MoA documents if needed.
Submit and await CT TRN
After submission, EmaraTax issues an acknowledgement number. FTA typically processes CT registration within 2–5 business days. You will receive your CT TRN by email and via the EmaraTax portal.
Late registration penalty — and when it can be waived
The penalty for failing to register for CT by the deadline is AED 10,000. This is a fixed administrative penalty, not a percentage-based charge.
FTA has indicated the penalty may be waived if the business files its first CT return (CT 300) within 7 months of the end of the financial year and the CT was paid on time, even if the CT registration was late. This waiver is not guaranteed and is assessed case by case — do not rely on it. Register immediately if overdue.
Corporate Tax registration in Dubai, Sharjah, Abu Dhabi & every emirate
One of the most common points of confusion: there is no separate Corporate Tax registration for Dubai, Sharjah, Abu Dhabi or any individual emirate. UAE Corporate Tax is a federal tax administered by the Federal Tax Authority (FTA), so the registration is identical wherever your trade licence was issued — the same EmaraTax portal, the same documents, the same AED 10,000 late penalty.
| Where your licence is issued | Who you register with | Process |
|---|---|---|
| Dubai (DED / DMCC / DAFZA / Meydan…) | Federal Tax Authority | EmaraTax — identical |
| Abu Dhabi (ADDED / ADGM / KIZAD…) | Federal Tax Authority | EmaraTax — identical |
| Sharjah (SEDD / SAIF / Shams / Hamriyah…) | Federal Tax Authority | EmaraTax — identical |
| Ajman, RAK, Fujairah, Umm Al Quwain | Federal Tax Authority | EmaraTax — identical |
So whether you searched for “corporate tax registration in Sharjah” or “corporate tax registration services in Abu Dhabi”, the answer is the same federal process described in the step-by-step section above. What can differ between emirates is your licence-renewal authority and free-zone rules — not the tax registration.
Free zone companies: registration is still mandatory
A free-zone company — even a one-person, zero-profit one — must register for Corporate Tax. The 0% headline you may have heard about applies only to a Qualifying Free Zone Person (QFZP), and only on qualifying income, and only if you register and meet every condition. You do not get 0% by default, and you never get it by skipping registration.
Corporate Tax registration is mandatory for all taxable persons regardless of revenue or profit. A dormant company, a holding company, or a freelancer on a free-zone permit all register the same way. Filing a NIL return later is normal — not registering is what triggers the AED 10,000 penalty.
To keep the 0% QFZP rate, non-qualifying (“excluded”) income must stay within the de minimis limit — the lower of AED 5 million or 5% of total revenue. Breach it and your entire profit is taxed at 9%. We cover the qualifying-income rules in the UAE Corporate Tax guide.
Small Business Relief, the 0% band & reliefs you can claim
Registering does not mean you will pay 9% on everything. Several reliefs and concessions reduce or eliminate the bill — but you must register and file to claim them.
| Your situation | Effective CT rate | Condition |
|---|---|---|
| Taxable income up to AED 375,000 | 0% | Automatic 0% band for every taxable person |
| Taxable income above AED 375,000 | 9% on the excess | Standard rate |
| Revenue ≤ AED 3,000,000 (Small Business Relief) | 0% (treated as no taxable income) | Must elect SBR; valid for tax periods ending on/before 31 Dec 2026 |
| QFZP — qualifying income | 0% | Meet QFZP conditions; stay within de minimis |
Small Business Relief and QFZP status are elections you make when you file — the FTA does not apply them for you. Estimate your bill first with our free UAE Corporate Tax calculator, then read the full guide to decide which relief fits.
Already missed your registration deadline? Your options
This is the most common Corporate Tax question in UAE business circles right now — and the good news is that the AED 10,000 late-registration penalty is, in most cases, waivable.
In 2025 the FTA introduced a penalty-waiver initiative: if you file your first Corporate Tax return (or annual declaration) within 7 months of the end of your first tax period, the AED 10,000 late-registration penalty is waived. If you have already paid it, the amount is credited back to your EmaraTax account.
Register immediately
Complete your EmaraTax registration now — every additional day of delay only increases scrutiny. The penalty is a fixed AED 10,000, not a daily charge, so registering today caps the exposure.
File your first return within 7 months of your period end
This is the trigger that activates the waiver. File the first Corporate Tax return or annual declaration inside the 7-month window — do not wait for the full 9-month deadline.
Check your EmaraTax account for the credit
If the AED 10,000 was already imposed or paid, confirm it has been reversed/credited after you file. Keep the confirmation.
Miss the 7-month filing window and the AED 10,000 stands, plus ordinary late-filing penalties accrue. If your deadline is close, prioritise filing over perfection — you can amend later. See the CT return checklist before you submit.
What UAE business owners actually ask about CT registration
These are the Corporate Tax questions UAE founders and small-business owners raise most often. We have answered each the way we would for a client.
“I got an AED 10,000 fine for registering late — can I still get it waived?”
In most cases, yes. The FTA’s waiver initiative cancels the penalty if you file your first Corporate Tax return or annual declaration within 7 months of the end of your first tax period. If you have already paid, it is credited back to your EmaraTax account. The single most important action is to file that first return inside the window — do not wait for the 9-month deadline.
“My free-zone company is one person with no profit — do I really have to register?”
Yes. Registration is mandatory for every taxable person regardless of size, profit, or free-zone status. Having no profit simply means you will file a NIL return — it does not exempt you from registering. Skipping registration is what creates the AED 10,000 exposure.
“How do I file a NIL Corporate Tax return?”
A NIL return is filed through EmaraTax exactly like any other return — you report zero taxable income. It is common for dormant companies, holding entities, and businesses electing Small Business Relief. You still must register first and file by your deadline. Our CT return checklist walks through the fields.
“I earn under AED 375,000 (or under AED 3M) — do I owe anything?”
Likely 0% — but you still register and file. Income up to AED 375,000 is taxed at 0% automatically; revenue up to AED 3 million can elect Small Business Relief and be treated as having no taxable income (for tax periods ending on/before 31 Dec 2026). Both still require registration and a return. Model it with the CT calculator.
“Is the registration process different in Sharjah or Abu Dhabi versus Dubai?”
No. Corporate Tax is federal, so the process is identical in every emirate — same EmaraTax portal, same documents, same deadlines. Only your licence-renewal authority and free-zone rules differ by emirate, not the tax registration itself.
Corporate Tax registration is separate from VAT. If your taxable turnover is near AED 375,000 you may also owe VAT registration — see our UAE VAT compliance checklist.

Frequently asked questions
Who must register for UAE Corporate Tax?
All UAE-incorporated entities (LLCs, PSCs, free zone companies, branches) and individuals with a trade licence. There is no minimum revenue threshold — every taxable person must register, including loss-making and zero-revenue businesses.
What is the penalty for late CT registration in UAE?
AED 10,000 fixed penalty. FTA may waive it if the first CT return is filed within 7 months of the financial year end and CT was paid on time, but the waiver is discretionary — not automatic.
Is CT registration separate from VAT registration?
Yes. Having a VAT TRN does not register you for Corporate Tax. CT registration is a separate process on EmaraTax and results in a separate CT Tax Registration Number (TRN).
How long does EmaraTax CT registration take?
Typically 2–5 business days after submitting all required documents. You receive the CT TRN by email and can view it on your EmaraTax dashboard.
What documents do I need for CT registration?
Trade licence, Memorandum and Articles of Association, Emirates ID and passport of the authorised signatory, financial year start and end dates, bank account details, and registered address.
When is the CT registration deadline for a new business?
For businesses incorporated after 1 March 2024, within 3 months of the date of incorporation or establishment. For natural persons with trade licences, by 31 March of the following Gregorian year.
What is the penalty for registering for Corporate Tax late in the UAE?
Failing to register for UAE Corporate Tax within the FTA’s specified timeline carries an AED 10,000 penalty under Cabinet Decision 75/2023. However, the FTA’s waiver initiative cancels this penalty if you file your first Corporate Tax return or annual declaration within 7 months of the end of your first tax period; amounts already paid are credited back.
Do free zone companies need to register for UAE Corporate Tax?
Yes. All free-zone companies must register, regardless of profit or whether they qualify for the 0% Qualifying Free Zone Person rate. The 0% rate applies only to qualifying income and only if you register and meet all QFZP conditions, including staying within the de minimis limit of AED 5 million or 5% of revenue.
Is Corporate Tax registration different in Dubai, Sharjah or Abu Dhabi?
No. UAE Corporate Tax is a federal tax administered by the Federal Tax Authority, so registration is identical in every emirate via the EmaraTax portal. There is no emirate-specific Corporate Tax registration.
Do I have to pay Corporate Tax if I earn under AED 375,000?
No Corporate Tax is due on taxable income up to AED 375,000 (taxed at 0%), and businesses with revenue up to AED 3 million can elect Small Business Relief to be treated as having no taxable income for tax periods ending on or before 31 December 2026. You must still register and file a return.
How do I file a NIL Corporate Tax return in the UAE?
A NIL return is filed through EmaraTax like any other return, reporting zero taxable income. It is common for dormant companies, holding entities and businesses electing Small Business Relief. Registration and timely filing are still required.
