Key Takeaways
4 insights · 18 min readEvery taxable person must register — mainland, free zone, branches, and natural persons whose business turnover exceeds AED 1 million — whether or not any tax is owed.
Missing your deadline triggers a fixed AED 10,000 penalty. Deadlines were set by FTA Decision No. 3 of 2024 by trade-licence month, and the resident-company deadlines have now passed.
The AED 10,000 penalty is waivable if you file your first return within seven months of your first tax period end — 31 July 2026 for a 31 December 2025 first period.
Registration is separate from VAT and issues a separate TRN. The whole process runs through EmaraTax and is usually approved within 20 business days.
Corporate tax registration is the mandatory process of registering with the Federal Tax Authority (FTA) to obtain a Tax Registration Number for corporate tax. Under Federal Decree-Law No. 47 of 2022, every taxable person must register — mainland, free zone, and natural persons above AED 1 million turnover — whether or not tax is owed. It is done online through EmaraTax, and missing your deadline costs a fixed AED 10,000.

What Is UAE Corporate Tax Registration?
It is the mandatory process of registering your business with the FTA to obtain a Tax Registration Number (TRN) for corporate tax purposes. Under Federal Decree-Law No. 47 of 2022, businesses pay 9% corporate tax on taxable income above AED 375,000 and 0% below. Every taxable person must register — whether they owe tax or not.
Registration is separate from filing. You must register before you can file your first return. The FTA assigns registration deadlines based on your trade licence issuance date under FTA Decision No. 3 of 2024, and missing the deadline triggers a fixed AED 10,000 administrative penalty. The entire process is completed online through EmaraTax at eservices.tax.gov.ae, and most registrations are processed within 20 business days.
Who Must Register for Corporate Tax in the UAE?
UAE corporate tax registration is mandatory for virtually every entity conducting business in the UAE.
| Entity type | Must register? | Notes |
|---|---|---|
| Mainland LLC / PJSC | Yes | All mainland companies, regardless of revenue |
| Free zone company | Yes | Even if qualifying for the 0% QFZP rate |
| Branch of a foreign company | Yes | If it has a permanent establishment (PE) in the UAE |
| Non-resident with a UAE nexus | Yes | Within 3 months of establishing the nexus |
| Sole establishment / sole proprietor | Yes (if > AED 1M) | Natural persons with business turnover over AED 1 million/year |
| Freelancer with a trade licence | Yes (if > AED 1M) | Same AED 1 million threshold applies |
| Government entities | Generally exempt | May still need to register for exemption recognition |
| Qualifying public benefit entities | Yes (for exemption) | Must register to have exemption recognised by the FTA |
⚠️ Registration is mandatory even if your tax liability is AED 0
A free zone company with 100% qualifying income still must register. A startup with zero revenue must register if it holds a trade licence. Failure to register is a flat AED 10,000 penalty. Not sure if you need to register? Ask us →
Corporate Tax Registration Deadlines 2026 — by Trade Licence Month
Under FTA Decision No. 3 of 2024 (effective 1 March 2024), deadlines for resident juridical persons incorporated before 1 March 2024 are based on the month the trade licence was issued — and, as at July 2026, they have all passed.
| Licence issued month | Registration deadline | Status (July 2026) |
|---|---|---|
| January – February | 31 May 2024 | Passed — register immediately |
| March – April | 30 June 2024 | Passed |
| May | 31 July 2024 | Passed |
| June | 31 August 2024 | Passed |
| July | 30 September 2024 | Passed |
| August – September | 31 October 2024 | Passed |
| October – November | 30 November 2024 | Passed |
| December | 31 December 2024 | Passed |
For companies incorporated on or after 1 March 2024: register within three months of incorporation or licence issuance. For natural persons (freelancers, sole proprietors): if your business turnover exceeded AED 1 million in the 2025 calendar year, register by 31 March 2026. If you hold multiple licences, the FTA uses the one with the earliest issuance date to set your deadline.
🔴 If your deadline has already passed
Register immediately. The AED 10,000 late-registration penalty can still be waived — see the penalty-waiver section below — but every day of further delay narrows the window, and filing your first return late is what forecloses it. Register now from AED 199 →
Documents Required for Corporate Tax Registration
Have every document ready before you start the EmaraTax application — missing documents cause rejection and delays. All are uploaded as clear colour PDFs.
| Document | Notes |
|---|---|
| Valid trade licence (+ all branch licences) | Must not be expired. Upload every branch licence if applicable. |
| Certificate of incorporation / MOA | Or the partnership agreement for partnerships. |
| Emirates ID & passport of owners (25%+ ownership) | Clear colour copies for every owner holding 25% or more. |
| Passport of the authorised signatory | The person submitting the application on behalf of the company. |
| Power of attorney / board resolution | Proving the signatory has authority to submit on behalf of the entity. |
| Commercial registration certificate | Or any official document from the licensing authority. |
Step-by-Step: How to Register on EmaraTax
Registration is completed entirely online at eservices.tax.gov.ae. The application has five sections inside a single flow — here is the process from login to TRN.
- Log in to the EmaraTax portal — go to eservices.tax.gov.ae and sign in with your email and password, or use UAE PASS for faster access. No account? Click Sign Up and register with your email and phone number.
- Create or select your taxable person — on the dashboard, select your entity if it is already linked, or click Create New Taxable Person, then go to Corporate Tax and Register for Corporate Tax.
- Complete the five registration sections — Entity details (entity type, trade licence details, financial year start/end, primary activity); Identification (emirate, legal address matching the trade licence, ownership for all 25%+ owners); Contact (primary contact, language and notification settings); Authorised signatory (signatory details and upload of the power of attorney or MOA); and Review & submit.
- Review and submit — verify every field, tick the declaration box and submit. You receive a reference number for tracking.
- Receive your TRN — the FTA reviews within 20 business days. Once approved, your Corporate Tax Registration Number is issued by email and SMS. Save it — you will need it for every future filing.
Would rather not navigate EmaraTax yourself?
Send us your trade licence and owner documents. An FTA-registered agent prepares and submits the whole registration and follows up until your TRN is issued — for a fixed AED 199.
How to Check Your Status and Download Your Certificate
After submitting, track progress in EmaraTax: log in, open your Taxable Person profile, click Corporate Tax in the left menu, and your status shows as Pending Review, Approved, or Returned for Amendment. If it is returned, the FTA specifies exactly what to correct — re-submit immediately, because the clock keeps running during the correction period.
Once the status shows Approved, download your certificate: open your Taxable Person profile, click Tax Registration, select Corporate Tax, open the Documents tab and click Download for the PDF. Your certificate includes your 15-digit corporate tax TRN, which must appear on all CT returns and FTA correspondence. It is different from your VAT TRN — do not use one in place of the other.
Common EmaraTax Registration Mistakes (and How to Avoid Them)
Most rejections come down to the same handful of avoidable errors.
| Mistake | Impact | How to avoid it |
|---|---|---|
| Expired trade licence uploaded | Application rejected | Renew the licence before starting registration |
| Mismatched ownership details | FTA queries, 2–4 week delays | Ensure the MOA matches passport details exactly |
| Wrong financial year dates | Incorrect tax period assigned | Use dates matching your accounting records |
| Missing branch licence | Incomplete registration | Upload all licences, including branches |
| POA not authorising the signatory | Application returned | Ensure the POA specifically names the signatory |
| Oversized upload files | Upload fails silently | Compress large PDFs before uploading |
| Assuming VAT registration covers CT | Missed CT registration, AED 10,000 | CT requires separate registration and a separate TRN |
| Natural person not registering | AED 10,000 penalty | Register if business turnover exceeds AED 1M/year |
The AED 10,000 Late Registration Penalty — and How to Get It Waived
Missing your registration deadline triggers a fixed AED 10,000 penalty under Cabinet Decision No. 10 of 2024. However, the FTA introduced a waiver: file your first corporate tax return within seven months of the end of your first tax period, and the penalty is waived — or refunded if already paid.
For a company whose first tax period ended 31 December 2025, the waiver deadline is 31 July 2026. Because these initiatives are time-limited and can be varied, confirm your current eligibility with the FTA before you file rather than after. The full penalty schedule — late filing, late payment and the rest — is set out in our UAE corporate tax penalties guide.
Corporate Tax Registration for Free Zone Companies
A common misconception is that free zone companies do not need to register. That is wrong. All free zone entities must register, regardless of whether they qualify for the 0% Qualifying Free Zone Person (QFZP) rate. Registration is what lets the FTA verify QFZP eligibility: without it you cannot file, and without filing the FTA cannot confirm your 0% status. A free zone company that fails to register risks losing its preferential treatment entirely. The process is identical to mainland companies — same portal, same documents, same deadline rules.
2026: audited financial statements are mandatory for QFZPs
Under Ministerial Decision No. 82 of 2023, every Qualifying Free Zone Person must maintain audited financial statements with its corporate tax return regardless of revenue, and any taxable person with revenue at or above AED 50 million must do the same. The audit must be carried out by a Ministry of Economy approved firm — arrange it through our free zone audit service.
Corporate Tax Registration for Natural Persons
Natural persons — sole proprietors, freelancers, individual entrepreneurs — must register if their total business turnover exceeds AED 1 million in a Gregorian calendar year. The following are excluded from the AED 1 million calculation: salary and employment income, personal investment income, and personal real-estate investment income.
Natural-person registration deadlines
• Turnover exceeded AED 1M in 2024 → register by 31 March 2025 (passed — register immediately).
• Turnover exceeded AED 1M in 2025 → register by 31 March 2026.
• Non-resident natural persons → within three months of becoming a taxable person.
Because there is no personal income tax in the UAE, a resident natural person is only in corporate tax scope on UAE business income once the threshold is crossed. If your turnover is at or under AED 3 million you may also be able to elect Small Business Relief and pay 0% — but you still have to register and file.
Corporate Tax Registration for Non-Resident Persons
Foreign companies and individuals without a UAE trade licence may still have to register if they have a Permanent Establishment (PE) or a taxable nexus in the UAE.
| Non-resident scenario | Registration deadline |
|---|---|
| PE created before 1 March 2024 | Within 9 months of the PE creation date |
| PE created on or after 1 March 2024 | Within 6 months of the PE creation date |
| UAE-sourced income with nexus (no PE) — before 1 March 2024 | 3 months from 1 March 2024 |
| UAE-sourced income with nexus (no PE) — from 1 March 2024 | 3 months from the date the nexus is established |
| Foreign company managed and controlled in the UAE | 3 months after the end of the financial year |
If your foreign company makes decisions from the UAE, holds meetings here, or has key management personnel in the UAE, you may be treated as a UAE tax resident under Place of Effective Management (POEM) rules — even if incorporated abroad. Seek professional advice if you are unsure of your status.
After Registration: What Happens Next?
Once you hold a TRN, the obligations continue. Registration is the start of compliance, not the end of it.
Your obligations after registration
• File your CT return within nine months of your financial year end — see our corporate tax filing 2026 guide for the deadlines.
• Pay any tax due by the same date — filing and payment deadlines are identical.
• Keep records for seven years — invoices, contracts, bank statements and financial statements.
• Hold audited financial statements if revenue is AED 50 million or more, or if you are a QFZP.
• Notify the FTA of changes — update EmaraTax via the Amendments flow if your name, address, ownership or financial year changes (you cannot submit two amendments for the same account at once).
• Deregister if you close — within three months of cessation. CT deregistration from AED 399.
