Every taxable person in the UAE must register for corporate tax through the Federal Tax Authority’s EmaraTax portal and obtain a Corporate Tax Registration Number — even a business that pays 0%, and even a company set up only to hold a licence or a visa. Registration is separate from, and comes before, filing and paying tax, and missing the deadline carries a fixed AED 10,000 penalty regardless of whether you owe a single dirham. This guide covers who must register, the deadlines, the EmaraTax process step by step, the penalty, and the waiver still available in 2026. For the wider regime, see our corporate tax compliance guide.
Who Must Register for Corporate Tax?
Registration is mandatory based on who you are, not on whether you are profitable. The main categories are:
- Resident juridical persons — all UAE companies, mainland and free zone, including Qualifying Free Zone Persons on the 0% rate.
- Natural persons (individuals) conducting business where total turnover exceeds AED 1 million in a Gregorian calendar year.
- Non-resident persons with a Permanent Establishment or a taxable nexus in the UAE.
Even exempt persons — such as certain government and public-benefit entities and qualifying funds — are generally required to register in order to claim their status.
| 0% is still registeredA free zone company on the 0% rate, and a company earning under the AED 375,000 threshold, must both still register and file. The rate is not the test — being a taxable person is. |
Corporate Tax Registration Deadlines
Deadlines are set by FTA Decision No. 3 of 2024 and depend on your category:
| Who you are | Registration deadline |
|---|---|
| Juridical person established before 1 March 2024 | A deadline based on the month your trade licence was first issued — a staggered schedule that ran through 2024 (now passed for almost all) |
| Juridical person established on or after 1 March 2024 | Within 3 months of the date of incorporation / establishment |
| Natural person (turnover over AED 1M) | By 31 March of the year following the relevant calendar year |
If your original deadline has passed, the advice is the same: register immediately. The penalty is a fixed amount that does not grow with further delay — but leaving the company unregistered keeps you exposed and delays your access to the waiver below.
How to Register on EmaraTax: Step-by-Step
1. Create or log in to your EmaraTax account. Via UAE Pass or email on the FTA portal.
2. Add the taxable person. Create the entity profile under your account.
3. Start the corporate tax registration. Select “Corporate Tax” and begin a new registration.
4. Enter your details. Entity type, trade licence information, business activities, and owners/shareholders.
5. Add the authorised signatory. With proof of authorisation.
6. Upload your documents. Trade licence, Emirates ID and passport of the owner(s) and signatory, and the Memorandum of Association.
7. Review and submit. The FTA reviews the application.
8. Receive your Tax Registration Number (TRN). Issued on approval — this is your corporate tax registration confirmation.
Documents Required
- Valid trade licence
- Passport and Emirates ID of the owner(s) / shareholders
- Passport and Emirates ID of the authorised signatory
- Proof of authorisation (e.g. power of attorney or board resolution)
- Memorandum / Articles of Association
- Company contact and address details
The AED 10,000 Late-Registration Penalty — and the Waiver
Failing to register by your deadline triggers a fixed AED 10,000 administrative penalty (under the UAE’s administrative-penalties schedule, Cabinet Decision No. 75 of 2023). It applies automatically and does not depend on whether you owe any tax.
The important relief: the FTA’s Late-Registration Penalty Waiver Initiative — in force since April 2025 and still available in 2026 — waives the AED 10,000 penalty if you file your first corporate tax return (or annual declaration, for exempt persons) within seven months of the end of your first tax period, rather than the usual nine. There is no separate application: meet the shorter deadline and the penalty is waived automatically, and if you have already paid it, the amount is credited back to your EmaraTax account. The waiver covers the registration penalty only — late-filing and late-payment penalties are not included.
| The 7-month ruleIf you registered late, you can still escape the AED 10,000 penalty by filing your first return within 7 months of your first tax-period end, instead of 9. Confirm your first tax period on EmaraTax before counting — it may differ from your accounting records. |
After Registration: Filing and Other Deadlines
Registration is the first step, not the last. Once registered:
- Your first corporate tax return is due within nine months of the end of your first tax period (or seven, if you are using the waiver).
- Keep accounting records and supporting documents for seven years.
- Watch the related obligations that sit alongside the return — transfer-pricing disclosure, and audited financial statements for free zone and larger companies.
Other penalties to avoid include late filing, late payment (charged on unpaid tax), and failure to file — all separate from, and not covered by, the registration-penalty waiver.
Free Zone and QFZP Companies
Free zone companies are not exempt from registration. A Qualifying Free Zone Person benefits from a 0% rate on qualifying income, but it must still register for corporate tax, obtain a TRN, and file a return — the 0% rate is claimed through the return, not by staying off the register.
