Previously, it used to be very simple. Businesses in the UAE operated in an almost tax-free environment that gave them global appeal for years. Which means if you had a business here, taxes on profit weren’t something you worried about.
But times have changed, and so has the regulatory landscape. With Corporate Tax becoming a permanent fixture in the UAE’s financial framework, every business, no matter how big, small, new, or old, regardless of whether they need to pay tax or not, has one thing to deal with: registration. And yes, it applies to Free Zones too.
Now let’s walk together through how to register for Corporate Tax in the UAE, step-by-step, without any confusion.
Who Needs to Register for Corporate Tax?
It’s crucial to know that UAE corporate Tax registration is mandatory for:
All resident companies in the UAE
Free Zone companies, even if they qualify for 0% tax under the Qualifying Free Zone Person (QFZP) rules
Non-resident entities that have a permanent establishment or earn income in the UAE
Any legal entity, regardless of size, that is conducting business in the region
So, it doesn't matter if you’re a mainland business, operating from a Free Zone, or a foreign company doing business here; if you generate taxable income in the UAE, registration isn’t optional.

Even if your tax liability is zero today, the Federal Tax Authority (FTA) still expects your business to be registered.
Corporate Tax Rates in the UAE
Before knowing how to register for corporate tax, it is salient to understand what you’re registering for.
0% tax on taxable income up to AED 375,000
9% tax on income above AED 375,000
15% tax for Multinational Enterprises that fall under OECD Pillar Two rules (global revenues of over EUR 750 million annually)
So if you’re a small business or a Free Zone entity with qualifying activities, you may not owe much, or anything, at least right now.
But again, registration is still required. That’s non-negotiable.
The Entire Process: How to Register for Corporate Tax in the UAE
If you’ve ever registered for VAT in the UAE, this will feel familiar. If not, don’t worry, it’s not complicated. Everything is done through the EmaraTax portal, the official platform used by the FTA.
Use accounting software that’s fully compliant with UAE VAT & Corporate Tax rules.
It’s different from your VAT TRN, don’t confuse the two.
Once registered, this TRN becomes your ID for all future filings, returns, audits, and interactions with the FTA.
Mistakes That Could Cost You
The process isn’t hard, but it’s easy to mess up if you rush through it.
Common issues you may face:
Entering the wrong trade license number
Leaving out group structure details
Uploading incomplete or incorrect documents
Assuming registration isn’t needed because you’re under the tax threshold
Doing everything two days before the deadline and expecting instant approval
If you avoid these, the rest should be smooth sailing.
FAQs
What If I Miss the Deadline?
A delay in registration could cost you:
AED 10,000 in penalties
Additional scrutiny during filing
Don't let paperwork be the reason you fall behind. Register early, and avoid the unnecessary chaos.
Does Corporate Tax Registration End with Getting the TRN?
Getting your Corporate Tax TRN is just the beginning. What comes next:
Setting up accounting systems to track taxable income
Understanding deductible vs. non-deductible expenses
Preparing for annual return filing
Keeping documents ready for potential FTA audits
If you’re already using any ERP platforms, now’s the time to align them with Corporate Tax reporting needs.
I Run A Small Business, What to DO?
If your revenue is under AED 3 million, you may qualify for Small Business Relief. This means even if you're registered, you can opt to be treated as if you have no taxable income, hence, 0% tax.
What About Free Zone Companies?
Just because you operate in a Free Zone and expect to pay 0% tax on certain activities doesn’t mean you get to skip registration.
The FTA still wants you registered. Why?
Because your tax rate might be zero, but the obligation to declare is still active.
Do Non-Resident Businesses Also Need to Register?
If you’re a foreign company and you have a Permanent Establishment (PE) in the UAE, registration is mandatory.
This could be:
A fixed office or facility
A dependent agent
Repeated business activity within the UAE
If you generate income here, the FTA expects you to register, regardless of whether you have a physical base.
Registering for Corporate Tax in the UAE means building a business that’s prepared for growth, recognized by regulators, and ready to scale with confidence.
