How to Register for UAE Corporate Tax
Every taxable person must register for UAE corporate tax on EmaraTax and obtain a registration number — including free-zone companies that expect the 0% qualifying rate, and businesses that expect to owe nothing at all. You will need your trade licence and the details of the owner or authorised signatory to complete the process on the portal. Registration is what creates your filing obligation: once you hold a corporate tax registration number, you must file a return for every tax period regardless of profit, loss or relief. Register on time — late registration carries an AED 10,000 penalty, waived if you file your first return within seven months of your first tax period end.

Prepare to register
Registration itself is broad in scope and relatively light on documents, but it has to happen before you can file anything. There is no revenue threshold that exempts a business from registering — the test is whether the entity is within the corporate tax regime at all, not whether it currently makes a profit.
- All taxable persons register, including free zones expecting the 0% qualifying rate and dormant entities.
- Have your trade licence and owner/authorised-signatory details ready before you start.
- Register through the EmaraTax portal using your existing FTA credentials, or create an account if this is your first registration.
- Confirm your legal entity type and tax period — these carry through to every return you file afterwards.
- Keep the registration number and confirmation somewhere your finance team can find it at filing time.
Avoid the AED 10,000 penalty
Timing links registration directly to the waiver, so the sequence matters as much as the registration itself. Businesses that register late but then file promptly can still avoid the penalty; businesses that register late and then also file late generally cannot.
- Late registration triggers an AED 10,000 penalty under the FTA penalty regime.
- The penalty is waived if the first tax return is filed within seven months of the end of the first tax period.
- Register as soon as your entity is within scope — there is no advantage to waiting.
- Retain proof of your registration date and your first filing date; both matter if the waiver is ever queried.
- If you registered late and are unsure whether the waiver applies, check before your first return is due, not after.
Registration is what creates the filing duty
A corporate tax return is a registration-driven obligation, not a profit-driven one. Once you hold a corporate tax registration number, you are expected to file a return for every tax period — even when the outcome is zero.
- A company making a loss still files a return for the period.
- A free-zone entity claiming the 0% qualifying rate still registers and still files.
- A business inside Small Business Relief still registers and elects the relief inside the return — the relief changes how much tax is owed, not whether you register or file.
- A dormant holding company with no activity still files, because dormancy does not remove the registration.
- Assuming "no profit, no filing" is one of the most common — and most avoidable — ways businesses accumulate late-filing penalties.
How registration ends
Registration does not expire on its own, and stopping is not something you decide unilaterally — it has to be approved. Until that approval comes through, the filing obligation continues exactly as before, so treat registration as an ongoing commitment rather than a one-off form.
- The only way to stop filing is to formally deregister and have the FTA approve the deregistration.
- Even after approval, a final return is still required covering the period up to cessation.
- Closing a trade licence is not the same as deregistering for corporate tax — the two processes are separate and both need to be completed.
- Keep your registration details current; changes to legal structure, ownership or trade licence should be reflected before your next filing, not discovered during it.
- A group with several licensed entities registers each taxable person separately unless those entities elect to form a tax group.
Frequently Asked Questions
For businesses registering for corporate tax — and for what registration commits you to afterwards.
Who must register for corporate tax?
All taxable persons, including free-zone companies that expect the 0% rate and businesses that expect to owe no tax at all. There is no revenue threshold below which registration is optional.
What do I need to register?
Your trade licence and owner or authorised-signatory details, submitted through EmaraTax. Exiloz confirms the exact document list for your entity type before you start, so the application goes through in one pass.
What if I register late?
A AED 10,000 penalty applies, but it is waived if you file your first corporate tax return within seven months of your first tax period end. Registering as soon as possible removes the risk entirely.
Do I have to register if my company has zero revenue or is dormant?
Yes. Registration is based on being within the corporate tax regime, not on current profit. A dormant or zero-revenue entity that is in scope still registers and still files each period.
Does registering affect my free-zone 0% status?
No — registration is a separate step from qualifying for the 0% rate. You register like any other taxable person, then evidence Qualifying Free Zone Person status each year in the return itself.
Can I deregister once my company closes?
Yes, but only through a formal deregistration approved by the FTA, and a final return covering the period up to cessation is still required. Closing your trade licence alone does not end the corporate tax obligation.
We operate several licensed entities — do we register once or separately?
Each taxable person registers separately and gets its own registration number, unless the entities are eligible for, and elect into, a tax group. Do not assume one registration covers related companies under common ownership.
Can Exiloz register us?
Yes. We complete your EmaraTax registration, confirm your first tax period, and set up your filing timeline so the waiver window and your first return are never in doubt.
