Answer first: UAE corporate tax registration is done on the FTA's EmaraTax portal and is mandatory for almost every business - new companies generally must register within 3 months of incorporation or face a AED 10,000 penalty. Existing businesses were required to register by specified deadlines tied to their licence renewal dates in 2024 and 2025. The registration process itself is free, but the cost of getting it wrong is steep. Here is the exact process, document by document.

UAE considerations
For UAE readers, the practical issue is rarely the headline tax concept alone. The decision depends on the company type, tax period, EmaraTax status, books, relief position, and whether the business operates from a mainland or free zone structure. Use this with Finsera's UAE corporate tax registration and filing page and monthly bookkeeping support so the tax position is tied back to records, not assumptions. Treat this guide as a planning aid, then verify the live position against FTA or Ministry of Finance guidance before filing or paying tax.
Common questions
- How much does UAE corporate tax registration cost? Registration on EmaraTax is free. There is no FTA fee for obtaining a Corporate Tax Registration Number. If you use a tax agent or corporate service provider, their professional fees apply separately. Finsera includes registration as part of its corporate tax readiness service.
- How long does corporate tax registration take? Straightforward registrations (single-owner mainland LLCs) are typically approved within 5-10 business days. Complex structures - multi-shareholder free zone entities, branches with foreign parents, or holding companies - can take 2-4 weeks if additional documentation is requested.
Who Must Register for UAE Corporate Tax
Every juridical person incorporated in the UAE - mainland LLCs, free zone companies, branches of foreign entities, and civil companies - must register for corporate tax. This includes entities in DMCC, IFZA, RAKEZ, JAFZA, ADGM, and every other licensing authority. The only exemption category is certain extractive businesses and government entities specified under Articles 6 and 7 of Federal Decree-Law No. 47 of 2022.
Natural persons (individuals operating as freelancers or sole proprietors) must register once their total turnover from business activities exceeds AED 1 million in a Gregorian calendar year. The registration deadline for natural persons is 31 March of the year following the year in which the threshold was crossed.
The tax itself applies at 0% on taxable income up to AED 375,000 and 9% on taxable income above that threshold, per Article 3 of the Decree-Law. Registration is the gateway to compliance - without it, you cannot file a return, elect Small Business Relief, or obtain a Tax Registration Number (TRN).

Documents You Need Before You Start
Gather these documents before logging into EmaraTax. The application cannot be saved mid-process in all cases, and partial submissions time out.
- Valid UAE trade licence - the original PDF from your licensing authority (DMCC, DED, IFZA, etc.). The licence number, activity code, and expiry date must match the portal exactly.
- Emirates ID or passport of every shareholder owning 25% or more of the entity, plus the authorised signatory. Non-resident shareholders need passport copies with visa pages where applicable.
- Memorandum of Association (MOA) and Articles of Association (AOA) - the most recent versions, attested by the relevant authority. Amendments must be included if ownership has changed.
- Authorisation proof - a signed board resolution or power of attorney naming the individual who will act as the authorised signatory for tax matters. This is critical for FTA correspondence.
- Financial year-end date - the month and day your accounting year closes. Most UAE companies use 31 December, but free zone entities and branches may use other dates aligned with parent-company reporting.
- Contact details - a UAE mobile number and email address that the FTA will use for all notifications. These cannot be changed without a formal amendment request.
- Bank account details - the IBAN of the UAE corporate bank account linked to the business. The FTA may verify this against licence records.
Step-by-Step Registration on EmaraTax
Follow these steps in order. The EmaraTax portal is accessible at tax.gov.ae.
Step 1: Create or Log Into Your EmaraTax Account
If your business is already registered for VAT, use the existing EmaraTax credentials. New users must create an account with a UAE mobile number for OTP verification. The account must be created in the name of the authorised signatory, not an agent.
Step 2: Navigate to Corporate Tax Registration
From the dashboard, select "Tax Registration" -> "Corporate Tax Registration". The system will pre-populate some fields if a VAT registration already exists. Verify every pre-filled field - errors here propagate into the TRN.
Step 3: Enter Business Details
Input the legal name of the entity exactly as it appears on the trade licence. Select the licence type (commercial, industrial, professional), the jurisdiction (mainland or specific free zone), and the activity code from the dropdown. Mismatches between the portal and the licence are the leading cause of registration rejection.
Step 4: Specify the Financial Year-End
Enter the financial year-end date. This determines your tax period and, critically, your first filing deadline. A 31 December year-end means your first corporate tax return is due by 30 September of the following year - 9 months after period end.
Step 5: Add Ownership and Authorised Signatory Information
Enter the details of every shareholder with 25% or more ownership: full name, nationality, Emirates ID or passport number, and ownership percentage. Upload the MOA/AOA and the authorisation document. The signatory declared here receives all FTA notices and is liable for compliance.
Step 6: Upload Supporting Documents
Upload the trade licence, Emirates ID/passport copies, MOA/AOA, and authorisation proof in PDF or image format. Files must be clear, legible, and under the size limit. Blurred uploads are rejected without explanation - this is the second most common delay.
Step 7: Review and Submit
Review every field. Errors in shareholder percentages, mismatched licence numbers, or missing authorisation documents will trigger a rejection that resets the timeline. Submit and record the reference number. The FTA typically issues the Corporate Tax Registration Number within 5-10 business days, though complex free-zone structures can take longer.
Registration Deadlines by Entity Type
| Entity Type | Registration Deadline | Penalty for Late Registration |
|---|---|---|
| New juridical person (LLC, free zone co.) | Within 3 months of incorporation | AED 10,000 |
| Existing juridical person (pre-2023) | Per FTA phased deadlines (now passed) | AED 10,000 |
| Natural person (freelancer/sole proprietor) | 31 March of the year after crossing AED 1M turnover | AED 10,000 |
| Branch of foreign company | Within 3 months of licence issuance | AED 10,000 |
| Liquidated/deregistered entity | Must deregister from CT; failure attracts penalties | Up to AED 10,000 |
The AED 10,000 late-registration penalty is fixed - it does not scale with revenue or time. However, the FTA introduced a penalty waiver for businesses that register late but file their first tax return within 7 months of their first tax period end, rather than the standard 9 months. This waiver was formalised in FTA decisions issued in 2024 and remains active as of mid-2026.

What Happens After You Register
Once the FTA approves the application, the business receives a Corporate Tax Registration Number - a distinct identifier separate from the VAT TRN. The FTA also issues a Tax Registration Certificate confirming the entity's tax period and year-end.
The first tax period begins on the date of incorporation (or licence issuance) and runs to the financial year-end. The first corporate tax return must be filed within 9 months of the tax period end. For a company incorporated on 1 January 2025 with a 31 December year-end, the first return is due by 30 September 2026.
After registration, the business must:
- Maintain accounting records on an accrual basis for 7 years
- File an annual corporate tax return even if no tax is payable
- Pay any tax due within the 9-month filing window
- Notify the FTA of any changes to licence, address, or authorised signatory within 20 business days
Failure to file a return after registering triggers separate penalties: AED 500 per month for the first 12 months of delay, escalating to AED 1,000 per month thereafter, per FTA Decision No. 3 of 2024.
The Corporate Tax Registration Number also enables the business to access other EmaraTax services, including tax reassessment requests, objections, and voluntary disclosure filings. Businesses that subsequently register for VAT (if they cross the AED 375,000 VAT threshold) will find the process faster since the FTA already holds the entity's core details.
