To register for corporate tax in the UAE, log in to the EmaraTax portal (tax.gov.ae) using UAE Pass, add your business as a “taxable person,” enter your trade license and owner details, upload your documents, and submit. Once the Federal Tax Authority (FTA) approves it, you get a Tax Registration Number (TRN). Every business must register even if it pays 0% tax. Missing your deadline can cost a fixed AED 10,000 penalty.
Corporate tax is now a normal part of running a business in the UAE. Every company, big or small, mainland or free zone, needs to register with the Federal Tax Authority and get a tax number. The good news? The whole process is online and simple once you know the steps.
This guide walks you through everything in plain language: what corporate tax is, who must register, your exact deadline, the documents you need, and how to complete the EmaraTax registration step by step. We also cover the penalty, the new penalty waiver, and the mistakes that trip most people up.
What Is Corporate Tax in the UAE?
Corporate tax is a tax on a company’s profit. The UAE brought it in under Federal Decree-Law No. 47 of 2022, and it started on 1 June 2023.
Before this, most UAE businesses paid no tax on their profits. Now they do. The UAE added this tax to match global tax rules and to grow other sources of income for the country. For most small businesses, the tax itself is low. But registering is not optional; it applies to almost everyone.
Corporate Tax Rates in the UAE (2026)
The rates are easy to remember:
| Taxable Profit | Corporate Tax Rate |
| Up to AED 375,000 | 0% |
| Above AED 375,000 | 9% |
There is also a 15% top-up tax for very large multinational groups that earn more than €750 million worldwide. This comes from a global rule called the OECD BEPS Pillar 2 framework. It does not affect most local businesses.
Free zone companies can still enjoy a 0% rate on their “qualifying income” if they meet certain conditions. We explain this near the end of the guide.
What Is EmaraTax?
EmaraTax is the official online tax portal run by the UAE Federal Tax Authority. The name comes from Emirates + Tax.
It is a single website where you handle all your tax work in one place. You can:
- Register for corporate tax and VAT
- Get your Tax Registration Number (TRN)
- File your tax returns
- Pay your tax
- Update your records and manage refunds
You can access it at tax.gov.ae and log in with your FTA account or UAE Pass. Registering through EmaraTax is the only official way to sign up for corporate tax; there is no other route.
Who Needs to Register for Corporate Tax?
Almost every business in the UAE must register. Here is who this includes.
Mainland Companies
All mainland businesses must register, including LLCs, sole establishments, and other legal setups. This is true even if you make little profit or none at all.
Free Zone Entities
Free zone companies must register too, even the ones that qualify for the 0% rate. Registering and paying tax are two different things. You still need a tax number.
Natural Persons (Individuals & Freelancers)
If you run a business or freelance under your own name, you must register only if your turnover crosses AED 1 million in a calendar year. Salary and personal rent income do not count toward this.
Foreign Companies & Non-Residents
Foreign companies must register if they have a permanent office in the UAE or earn income from a UAE source. The rules here can be tricky, so it is worth getting advice.
Corporate Tax Registration Deadlines
Your deadline depends on when your business was set up, not on how much you earn.
If your company was set up before 1 March 2024, your deadline was based on the month your trade license was first issued (under FTA Decision No. 3 of 2024):
| Trade License Issued In | Registration Deadline |
| January – February | 31 May 2024 |
| March – April | 30 June 2024 |
| May | 31 July 2024 |
| June | 31 August 2024 |
| July | 30 September 2024 |
| August – September | 31 October 2024 |
| October – November | 30 November 2024 |
| December | 31 December 2024 |
Note: All of these dates have now passed. If your company existed before March 2024 and you have not registered yet, you are already late, but keep reading, because the penalty waiver below may help you.
If your company was set up on or after 1 March 2024, the rule is simpler:
- New UAE companies (mainland and free zone): register within 3 months of incorporation.
- Non-resident with a permanent establishment: register within 6 months of setting it up.
- Natural persons with over AED 1 million turnover: register by 31 March of the next year.
If your company holds more than one license, use the earliest license date to work out your deadline.
Documents Required for Registration
Prepare these before you start. Most delays happen because a document is missing or unclear.
For companies (legal entities):
- Valid trade license
- Memorandum of Association (MOA)
- Emirates ID and passport copies of owners and directors
- Shareholder and ownership details (anyone owning 25% or more)
- Registered business address in the UAE
- Corporate bank account details (IBAN)
- Financial year details
For individuals (natural persons):
- Emirates ID or passport
- Trade or commercial license
- Proof of income or turnover
Upload files in PDF or JPEG format, and keep each file under 5 MB, as the portal requires.
How to Register on EmaraTax Step by Step
Once your documents are ready, the online process takes only a short time.
Step 1: Log in to EmaraTax. Go to tax.gov.ae and sign in with your FTA account or UAE Pass. New users should create an account first.
Step 2: Add your taxable person. On your dashboard, add your business as a “taxable person” and pick the correct category.
Step 3: Start corporate tax registration. Find the Corporate Tax tile and click Register. Read the short guidelines and click Start.
Step 4: Enter business details. Add your entity type, trade license number, business activities, and financial year. Match these exactly to your license.
Step 5: Add owners and branches. List anyone who owns 25% or more. If you have branches, add each one.
Step 6: Add the authorized signatory. Enter the details of the person allowed to sign for your business, and upload proof such as a Power of Attorney or MOA.
Step 7: Review and submit. Check every field, tick the declaration box, and click Submit. You will get an application reference number to track your request.
Tip: Screenshots of each EmaraTax screen make this even easier to follow. If you get stuck on any step, a business setup consultant can complete it for you.
What Happens After You Submit?
The FTA reviews your application. This usually takes a few days to a few weeks. You can check the status any time on your EmaraTax dashboard.
Once approved, you receive your Tax Registration Number (TRN) by email and inside EmaraTax. Save it; you will need it for every future tax filing.
What If Your Application Is Rejected?
Sometimes the FTA asks for more details or rejects an application. This is usually easy to fix. Common reasons include:
- A name or license number that does not match your documents
- A missing or blurry document
- The wrong person listed as the signatory
If this happens, correct the issue and re-submit. The FTA will tell you what was wrong, so read their message carefully before trying again.
Penalties for Late or Incorrect Registration
The most important number to know is AED 10,000.
| Mistake | Penalty |
| Late registration | AED 10,000 (fixed, one-time) |
| Late filing of tax return | Separate FTA penalty applies |
| Incorrect or late tax payment | Separate FTA penalty applies |
The late registration fine is set under Cabinet Decision No. 10 of 2024. It is a fixed one-time charge; it does not grow the longer you wait, but registering right away stops any further risk.
The Good News: The Penalty Waiver
Here is the update many older guides miss. Since 14 April 2025, the FTA waives the AED 10,000 late registration penalty if you file your first corporate tax return (or annual declaration) within 7 months of the end of your first tax period instead of the usual 9 months.
You do not need a separate application. The waiver is applied automatically through EmaraTax once you register and file on time. If you already paid the fine, it is refunded as a credit to your EmaraTax account. This has already helped tens of thousands of UAE businesses clear their penalties.
Common Mistakes to Avoid
- Thinking 0% means no registration. Even 0% and free zone businesses must register.
- Using the wrong address. Use your own registered business address, not your accountant’s.
- Mismatched details. Names and license numbers must match your trade license exactly.
- Wrong financial year-end. This sets your filing deadline, so get it right.
- Waiting too long. The AED 10,000 fine hits even if you owe no tax.
- Leaving out an owner. List every shareholder with 25% or more.
Free Zone Companies Special Rules
Free zone businesses can keep a 0% tax rate on qualifying income, but only if they follow the rules. To stay eligible, a free zone company should:
- Keep real substance (a genuine office and staff) in the UAE
- Follow transfer pricing rules
- Meet the Ministry of Finance conditions for a “Qualifying Free Zone Person”
Doing regular business with the UAE mainland can affect this 0% status. If you are unsure, check with a tax advisor before you file.
Conclusion
Registering for corporate tax in the UAE is a simple, fully online process when you prepare your documents first. Every business needs to do it even at 0%, and the smartest move is to register early. That way you avoid the AED 10,000 fine, keep your business in good standing, and stay ready for filing season.
If your deadline has passed, don’t panic. Register on EmaraTax and file your first return within the 7-month window, and the penalty may be waived automatically.
