UAE Corporate Tax (CT) registration is not optional — it is mandatory for every UAE-incorporated company and free zone entity, whether you are profitable or not. The registration is done entirely online through the FTA's EmaraTax portal and, once completed, issues you a Corporate Tax Registration Number (CTRN). This guide walks through the entire process screen by screen.
⚠️ Deadline: CT registration deadlines are based on your trade licence issuance date. Businesses licensed before March 2024 had staggered deadlines — many of which have passed. If you have not yet registered, you are accruing a penalty of AED 10,000. Register now.
1. Before You Start: Documents Required
| Document | Format | Notes |
|---|---|---|
| Trade Licence | PDF or image | Must be current (not expired) |
| Memorandum of Association (MOA) | For LLCs — all pages including amendments | |
| Certificate of Incorporation | From DED, DMCC, ADGM, or relevant authority | |
| Passport copies of all authorised signatories | PDF or image | Plus Emirates ID if UAE resident |
| Emirates ID of authorised signatory | PDF or image | If registrant is a UAE resident |
| Financial year start and end dates | Information only | The 12-month period your CT is based on |
| Accounting basis | Information only | Accrual recommended; cash basis for certain SMEs |
| UAE Pass account | Login credential | Required to access EmaraTax — register at uaepass.ae if needed |
2. Step-by-Step: Registering on EmaraTax
Step 1 — Access EmaraTax
Go to emaratax.gov.ae and click "Login / Sign Up." Use your UAE Pass to authenticate. UAE Pass is the government's official digital identity system — if you don't have it, download the app and create an account with your Emirates ID before starting.
Step 2 — Create or Select Your Taxable Person
After logging in, you will see the EmaraTax dashboard. If this is your first registration, click "Register a Taxable Person." Select the entity type:
- UAE Resident Juridical Person — for mainland LLCs, FZEs, FZCOs, branches
- Non-Resident Juridical Person — for foreign companies with UAE Permanent Establishment
- Natural Person — for individuals with AED 1M+ annual business income
- Unincorporated Partnership — for joint ventures and partnerships
Step 3 — Enter Trade Licence Details
Enter your Trade Licence Number, Licensing Authority (DED Dubai, ADHA Abu Dhabi, DMCC, etc.), and Licence Expiry Date. The portal auto-fetches your company name from the relevant licensing authority database in most cases.
Step 4 — Set Financial Year Dates
Enter your Financial Year Start Date and Financial Year End Date. For most UAE companies this is 1 January to 31 December. Free Zone entities may use different year-ends. This defines your first tax period — you cannot easily change this after submission.
💡 Year-End Tip: If your business has been operating for less than 12 months, your first tax period may be shorter. For example, a company incorporated on 1 September 2023 with a December year-end has a first tax period of only 4 months (Sep–Dec 2023).
Step 5 — Add Authorised Signatory
Add the details of the person authorised to sign CT returns on behalf of the company (usually a director, owner, or CFO). Required fields: Full legal name, nationality, passport number, date of birth, Emirates ID number (if applicable), email address, and mobile number.
Step 6 — Upload Documents
Upload all required documents. Each file must be under 5MB. Accepted formats: PDF, JPG, PNG. Ensure the Trade Licence is current — if it expires within 30 days, renew it first as the FTA may reject an expired licence.
Step 7 — Review and Submit
Review all entered information on the summary screen. Check: company name matches trade licence exactly; financial year dates are correct; all signatory details are accurate. Click "Submit." You will receive an email confirmation with a reference number.
Step 8 — Receive Your CTRN
The FTA typically processes CT registrations within 5–20 business days. You will receive a Corporate Tax Registration Number (CTRN) — a unique 15-digit identifier — by email and on your EmaraTax dashboard. This number is required on all CT correspondence and declarations.
3. Common EmaraTax Registration Errors (And How to Fix Them)
| Error | Cause | Fix |
|---|---|---|
| Trade licence not found | Licence number entered incorrectly or not yet updated in authority database | Double-check number format; try without dashes/spaces |
| Document upload fails | File too large (>5MB) or wrong format | Compress PDF or convert to JPG; keep under 4MB |
| UAE Pass authentication fails | Emirates ID not linked to UAE Pass | Log into UAE Pass app and link your Emirates ID first |
| Financial year dates rejected | Start date before licence issuance date | Use the actual licence issuance date as start date |
| Signatory not found | Name mismatch with Emirates ID records | Enter name exactly as it appears on Emirates ID |
| Registration stuck in "Under Review" | Missing document or data discrepancy | Log into EmaraTax → My Applications to check for FTA queries |
4. After Registration: What Comes Next
- File your first CT return within 9 months of your financial year end

5. Frequently Asked Questions
How long does UAE CT registration take?
The FTA typically processes Corporate Tax registrations within 5–20 business days from the date of complete submission. Complex cases (foreign entities, multiple partners) may take up to 30 days. You can track your application status in real-time through EmaraTax → My Applications.
Can I register for CT if I don't have a UAE Pass?
UAE Pass is the only authentication method accepted on EmaraTax. UAE nationals and residents can register via the UAE Pass app using their Emirates ID. Foreign company representatives without UAE residency should engage a UAE-resident authorised representative who has UAE Pass, or apply for UAE Pass through the ICP (Federal Authority for Identity and Citizenship).
Do I need to re-register if I already have a VAT TRN?
Yes — your VAT TRN and Corporate Tax CTRN are separate registrations. Being VAT-registered does NOT automatically register you for Corporate Tax. You must complete the CT registration process separately on EmaraTax, even if your VAT profile is already active.
