Topic Summary
Know the AED 10,000 Late Registration Penalty
The FTA charges a flat AED 10,000 fine if you miss your corporate tax registration deadline by even one day. There is no grace period, so checking your exact deadline on the EmaraTax Obligations tab is essential.
Understand the 9% Tax Rate and Threshold
UAE corporate tax is 9% only on taxable income above AED 375,000, while income at or below that level is taxed at 0%. A company earning AED 500,000 net pays just AED 11,250 in tax, not 9% of the full amount.
Confirm Whether Your Business Must Register
All UAE mainland companies, free zone companies, and foreign businesses with a permanent base in the UAE must register for corporate tax regardless of size or profit. Even companies that qualify for the 0% free zone rate are not exempt from registration.
Gather Your Documents Before Logging In
Having your trade license, passport copy, Emirates ID, memorandum of association, and financial year start date ready before opening EmaraTax can reduce the sign-up process to under 30 minutes. Free zone companies also need their certificate of incorporation and share register.
Create or Link Your EmaraTax Account First
Start at tax.gov.ae and either sign up for a new account or log in if your company is already VAT-registered. Linking UAE Pass pre-fills your Emirates ID details and speeds up the process significantly.
Complete the Five-Screen Registration Form Carefully
The EmaraTax registration form covers company details, owner information, and document uploads across five screens. Reviewing the summary screen before submitting helps catch errors that could delay your Tax Registration Number.
Expect Your TRN Within 20 Business Days
After a successful submission, the FTA issues your Tax Registration Number by email within 20 business days at no cost. Registration and annual filing are separate obligations, so receiving your TRN is just the first step.
In 2026, every company in the UAE must be on the FTA register for corporate tax. Miss the sign-up window and the FTA charges a fine of AED 10,000 on the spot. The tax rate is 9% on income above AED 375,000. Income at or below that threshold is taxed at 0%. The portal is free to use. Your Tax Registration Number (TRN) arrives within 20 business days. Late registration costs AED 10,000, even if you miss by one day.
This guide walks you through corporate tax registration UAE: EmaraTax step by step. You will learn what the sign-up means, who must do it, what papers you need, and how to move through each screen on the EmaraTax portal without a mistake.
What Is Corporate Tax Registration and Why It Matters
Corporate tax registration in the UAE means adding your company to the Federal Tax Authority's register so it can file and pay the 9% corporate tax. Every UAE company must do this, whatever its size or profit level. Skipping it triggers an AED 10,000 fine from the FTA (Federal Tax Authority, 2024).
UAE corporate tax applies at 9% on taxable income above AED 375,000. Income at or below that level is taxed at 0%, giving small companies a real buffer. Registration is separate from filing: you sign up first, then file each year.
Income Band | Tax Rate |
|---|---|
At or below AED 375,000 | 0% |
Above AED 375,000 | 9% |
A trading firm earning AED 500,000 net pays 9% only on the AED 125,000 above the threshold. That is AED 11,250 in tax for the year, not 9% of the full AED 500,000.
Who Must Register and When
The rules are straightforward. Here is who must complete corporate tax registration UAE:
All UAE mainland companies, from the date they are set up
Free zone companies, even those that qualify for the 0% rate
Foreign companies with a permanent base in the UAE
The FTA sets each company's deadline based on its trade license issue date. Check your exact deadline on the Obligations tab inside your EmaraTax account. Miss the deadline by one day and the AED 10,000 penalty applies with no grace period. For more detail, see our guide on EmaraTax account setup for a new UAE company.
Papers You Need Before You Start
Before you open EmaraTax, gather your trade license, passport copy, Emirates ID, company memorandum or articles, and your financial year start date. Having these ready before you log in cuts the sign-up time to under 30 minutes.
Documents for Mainland Companies
Valid trade license issued by DET or the relevant mainland body
Passport copy of each owner or director
Emirates ID of the UAE-resident owner or authorised signatory
Memorandum of association or articles showing company structure
Bank account details: IBAN and bank name
Documents for Free Zone Companies
Free zone companies need the incorporation certificate as well as the trade license. The two documents together confirm both your legal existence and your trading rights. Prepare these:
Free zone trade license, for example a DSBH license
Certificate of incorporation from the free zone authority
Passport and Emirates ID of the authorised signatory
Share certificate or register showing ownership
Confirmation of your financial year end date from your accountant

How to Complete Corporate Tax Registration UAE: EmaraTax Step by Step
Log in to EmaraTax at tax.gov.ae, create or link your account, select 'Corporate Tax' from the dashboard, and complete the five-screen form with your company and owner details. Upload your papers, review the summary, and submit. The FTA issues your Tax Registration Number by email within 20 business days (Federal Tax Authority, 2024).
Step 1: Create Your EmaraTax Account
Go to tax.gov.ae and click 'EmaraTax'
Choose 'Sign Up' if your company has no existing FTA account
Choose 'Log In' if your company is already VAT-registered
Enter your email, set a password, and confirm via the link the FTA sends
Link your UAE Pass: it pre-fills your Emirates ID details and saves time
Step 2: Open the Corporate Tax Form
From the dashboard, select 'Register for Corporate Tax'. The form has 5 screens: entity details, owner details, activity details, financial year, and review. Fill each screen fully before clicking 'Next'. The portal does not save partial screens. Pick your business activity from the drop-down list carefully, as this affects how the FTA groups your filing.
Step 3: Upload Papers and Submit
Upload each file as a PDF or JPG under 5 MB
The portal flags missing files in red before you reach the review screen
On the review screen, read every field: errors at this stage are free to fix
Click 'Submit': the FTA sends a confirmation email right away with a reference number
Your TRN arrives by email within 20 business days
If the TRN does not arrive after 20 business days, contact the FTA via the help centre at tax.gov.ae. For help with banking and taxation services, DSBH's support team can point you to the right contacts.
What Free Zone Companies Must Know Before They Register
Free zone companies must register for corporate tax even if they qualify for the 0% Qualifying Free Zone Person rate. They still file a return each year. The 0% rate only applies if the company meets the FTA's conditions, including earning income from outside the UAE or from other free zone firms (u.ae, 2024).
A free zone company can pay 0% corporate tax as a Qualifying Free Zone Person (QFZP). The conditions are:
It must earn 'qualifying income': mainly from foreign clients or other free zone firms
It must not have a mainland presence in most cases
It must keep proper books and file a return every year, even at 0%
Failing one condition drops the company to the standard 9% rate for that year
The process on EmaraTax is the same for free zone and mainland companies. Use your DSBH trade license and incorporation certificate as the main identity papers. Select 'Free Zone' as your entity type on screen 1 of the form. DSBH's business support team can check your papers before you submit to avoid delays.
Is registration mandatory even if I earn below AED 375,000?
Yes. Every UAE company must register for corporate tax regardless of income. A company earning AED 200,000 still registers and still files a return each year. It simply pays AED 0 in tax. Skipping registration triggers the AED 10,000 fine even if no tax is owed.
Common Errors That Delay Your Sign-Up
The most common reasons EmaraTax rejects a corporate tax sign-up are mismatched names between the trade license and passport, an expired license uploaded by mistake, and a wrong financial year start date. Each error sends the form back to draft and restarts the FTA review clock.
UAE Corporate Tax Key Figures at a Glance
Detail | Figure |

A missing word like 'LLC' or 'FZ-LLC' causes a rejection
Owner names must match the passport exactly, including middle names
If the license was recently renewed, upload the new one, not last year's
Financial Year and Activity Errors
The financial year start date must match your actual books
Picking the wrong activity code can cause the FTA to query your filing later
Check your activity code on your trade license before you start the form
You cannot change the financial year after submission without contacting the FTA directly
If you spot an error after submission, contact the FTA via tax.gov.ae right away. Do not submit a second application. You can also check the full list of business activities to confirm the right code before you start.
Deadlines, Fines, and What Happens After You Register
The FTA sets each company's registration deadline based on its license date. Miss it and you pay AED 10,000. After you register, you receive a Tax Registration Number and must file a corporate tax return within 9 months of your financial year end. Late filing carries its own separate fine (Ministry of Finance, 2024).
The fine is AED 10,000. It applies from the first day you are late, with no warning letter first. Check your exact deadline by logging into EmaraTax and looking at the Obligations tab.
License Issued | General Registration Deadline |
|---|---|
January 2023 or before | June 2024 (general guide) |
After January 2023 | Check Obligations tab in EmaraTax |
Filing Your First Return
Your first return is due within 9 months of your financial year end
You file it on EmaraTax using the same account you created for sign-up
Income below AED 375,000 means you file and pay AED 0
Keep your books for at least 7 years: the FTA can ask to see them at any time
Record-keeping is not optional. Federal Decree-Law No. 47 of 2022 sets out the 7-year duty. For help staying on top of your duties, DSBH's banking and taxation services team can point you to the right advisors.
What happens if I miss the filing deadline after I register?
Missing the annual filing deadline after registration triggers a separate fine from the FTA. The late registration fine and the late filing fine are distinct penalties. Registering on time does not protect you from a filing fine if you miss the 9-month window. File on time even if your tax bill is AED 0.
Where to Get Help
The FTA help centre at tax.gov.ae includes live chat and a call centre
The UAE government portal at u.ae has a plain-language guide to corporate tax
DSBH's business support team can review your papers before you submit to the FTA
For complex group structures, talk to a UAE-licensed tax agent before you start the form
Corporate tax registration UAE via EmaraTax is a one-time task. It takes under an hour when your papers are ready. Log in, fill the five screens, upload your files, and submit.
