How to register for corporate tax in the UAE online through EmaraTax

What is corporate tax registration in the UAE?

Corporate tax registration in the UAE is the process of enrolling a business with the Federal Tax Authority (FTA) to obtain a Corporate Tax Registration Number. It applies to mainland companies, free zone entities, and many natural persons running a business. Registration happens online through the EmaraTax portal under Federal Decree-Law 47 of 2022.

If you are searching for how to register corporate tax UAE online, this guide walks you through every step, the documents you need, the fees involved, and the deadlines that apply. The process sits inside the wider UAE Corporate Tax framework, which sets a 0% rate up to AED 375,000 of taxable income and 9% above that threshold.

Who must register for corporate tax in the UAE

Almost every business with a UAE trade licence must register, even if it expects to pay zero tax. The FTA treats registration as a separate obligation from filing or payment.

Mandatory registrants

• Mainland LLCs, PJSCs, and PSCs.
• Free zone companies, including Qualifying Free Zone Persons (QFZPs).
• Branches of foreign companies operating in the UAE.
• Natural persons (sole proprietors and freelancers) with annual turnover above AED 1,000,000.
• Non-resident juridical persons with a UAE permanent establishment or nexus.

Exempt persons who may still need to register

Government entities, qualifying public benefit entities, pension funds, and certain investment funds may be exempt from paying tax but often still need to apply for exemption through EmaraTax. Check your category on the Federal Tax Authority website before you start.

How to register corporate tax UAE online: the full process

You complete the entire registration on EmaraTax, the FTA's unified tax portal. The steps below assume you are registering a juridical person for the first time.

Step 1: Create or log in to your EmaraTax account

Visit eservices.tax.gov.ae. New users sign up with an email and UAE mobile number, or log in with UAE Pass. If you already hold a VAT Tax Registration Number (TRN), use the same credentials. Your existing taxable person profile will appear on the dashboard.

Step 2: Add or select your taxable person

On the dashboard, click "Add New Taxable Person" if the entity is new, or select the existing taxable person tile. Then choose "Corporate Tax" and click "Register".

Step 3: Complete the entity details

Enter your trade licence information, legal name in English and Arabic, legal type, and date of incorporation. The system will ask for your business activities as listed on the licence. If you operate in a free zone, indicate the free zone authority and licence number.

Step 4: Add identification and contact information

Provide the Emirates ID and passport copies of owners, partners, and authorised signatories. Add the registered office address, P.O. Box, and a primary contact email and mobile number. The FTA sends all official notices to these channels.

Step 5: Declare your financial year

Specify your financial year start and end dates. Most UAE businesses use January to December, but you can keep your licensed financial year. This date sets your first tax period and your filing deadline.

Step 6: Upload supporting documents

Attach scanned copies in PDF, JPG, or PNG format, each under 5 MB. A full list of files appears in our Corporate Tax Registration Documents Required guide.

Step 7: Review and submit

Check every field, accept the declaration, and submit. EmaraTax issues a reference number immediately. The FTA usually responds within 20 business days, often faster. Approved applicants receive a Corporate Tax Registration Number by email.

Documents you need before you start

Gather these files before opening EmaraTax. Missing documents are the most common reason for delays.

Corporate tax registration deadlines

The FTA set staggered deadlines based on the month your trade licence was issued. Missing your deadline triggers an administrative penalty of AED 10,000.

Deadlines for resident juridical persons

Entities incorporated on or after 1 March 2024 must register within 3 months of incorporation. For the latest cut-off rules see our UAE Corporate Tax Registration Deadline page.

Fees and timelines

The FTA does not charge a fee for online corporate tax registration through EmaraTax. You only pay if you request a printed Tax Registration Certificate, which costs AED 500 per copy. Tax agent fees and PRO charges are separate. A full breakdown lives in our UAE Corporate Tax Registration Cost article.

How long does approval take?

Most applications are processed within 20 business days. If the FTA needs more information, you receive a clarification request through EmaraTax. You then have 60 calendar days to respond, or the application is rejected and you must resubmit.

Special cases

Free zone companies

Free zone entities follow the same EmaraTax flow but must indicate their free zone authority and confirm whether they intend to claim QFZP status. QFZPs pay 0% on qualifying income and 9% on non-qualifying income. The Corporate Tax Registration for Free Zone Companies guide covers the qualifying activities list and substance requirements.

Natural persons and freelancers

Sole proprietors and freelancers with annual turnover above AED 1,000,000 in a calendar year must register by 31 March of the following year. Income from employment, personal investments, and real estate is not counted.

Tax groups

A UAE parent and its 95% owned subsidiaries can form a tax group and file a single return. Each member registers individually first, then the parent applies for tax group status on EmaraTax.

After you receive your Corporate Tax Registration Number

Registration is only the first obligation. Keep these milestones in mind.

• Maintain accounting records for at least 7 years.
• File your corporate tax return within 9 months of your financial year end.
• Pay any tax due by the same 9-month deadline.
• Update EmaraTax within 20 business days if your licence, address, or activities change.
• Consider small business relief if your revenue stays under AED 3,000,000 through 2026.

Common mistakes to avoid

• Using an expired trade licence on the application.
• Mismatching Arabic and English legal names.
• Selecting the wrong financial year, which locks your first filing date.
• Forgetting to attach the Memorandum of Association for LLCs.
• Ignoring the FTA clarification email within the 60-day window.
• Assuming free zone status means you do not need to register. Every free zone entity must register.

You can confirm any rule directly on the UAE Ministry of Finance portal, which publishes the underlying Cabinet and Ministerial Decisions.

Connecting registration to e-invoicing readiness

Corporate tax registration is one of three FTA obligations that increasingly link together: corporate tax, VAT, and e-invoicing. From 1 January 2027, businesses with revenue above AED 50 million must issue Peppol PINT AE invoices through an accredited service provider (ASP). Smaller businesses follow on 1 July 2027. Keeping your EmaraTax profile clean now makes ASP onboarding far smoother later. Read the full UAE Corporate Tax overview to see how the pieces fit.

EInvoice Direct is UAE e-invoicing software from Massive FZCO that ships with an accredited service provider included at no extra charge.
