Corporate tax registration and compliance in the UAE is a mandatory requirement for businesses operating in the mainland to ensure smooth operation, regulatory compliance, and to comply with the UAE’s evolving tax framework. Since mainland businesses are subject to UAE corporate tax, making timely registration helps to stay compliant, prevent penalties, avoid unnecessary risk, and support business stability.
Learn everything about UAE mainland corporate tax registration, covering eligibility, filing, deadline, document details, and Emaratax portal steps, and post TRN compliance, highlighting the need for expert support from corporate tax consultants in the UAE, and recommend for error-free compliance.
Overview of corporate tax in the UAE
Introduced under Federal Decree Law 47 of 2022, UAE corporate tax applies to net business profits from the financial year starting on or after 1 June 2023 onwards and is administered by the UAE Federal Tax Authority.
The tax structure is straightforward:
- 0% corporate tax applies to taxable income up to AED 375,000
- 9% corporate tax applies to taxable income exceeding AED 375,000
A key compliance point is that all taxable businesses must register for UAE corporate tax and file annual returns, even when profits are below AED 375,000 and no tax liability arises.
List of Entities Required to Register Under UAE Corporate Tax Law
Corporate tax registration applies across multiple entity structures. For UAE mainland companies, the following entities must register.
- Every UAE mainland business structure, including LLCs, sole proprietorships, and civil companies.
- Freelancers, sole proprietors, and other individuals conducting licensed business with annual income exceeding AED 1 million.
- Foreign-owned branches conducting business activities on the UAE mainland
- Non-incorporated entities and partnerships conducting business operations in the UAE
Key point: UAE mainland branches of local companies are treated as separate parent entities and therefore do not require separate corporate tax registration or filing in the UAE. The parent company is responsible for corporate tax compliance on behalf of its branches.
While Free Zone entities may qualify for 0% rate on qualifying income, they are still obligated to register with the UAE FTA and submit an annual tax filing.
Documents to Keep Ready for EmaraTax Registration
Businesses registering for UAE corporate tax must prepare the following documents before accessing the Emaratax portal to ensure a smooth registration process.
- Valid trade license, including a license from a branch
- Memorandum of Association (MoA) and Articles of Association (AoA)
- Emirates ID and passport copies of authorised signatories and shareholders
- VAT Tax Registration Number (TRN), if the entity is already registered for VAT in the UAE
- Financial year-end date applicable for Corporate Tax purposes
- Contact details of the business
- Proof of authorized signatory status, such as a board resolution if required by the UAE FTA.
Reminder: Ensure consistency across all submitted documents and registration details. Even a minor mismatch between the information on your trade license and the data entered in the Emara tax portal may result in delayed approval of the corporate tax registration application.

Guide to UAE Corporate Tax Registration via EmaraTax Portal
Mainland entities must register for corporate tax through the FTA’s Emaratax portal (eservices.tax.gov.ae). The online platform is accessible 24/7. With proper documentation, the registration procedure typically requires around 25 minutes.
Step 1: User login/Account setup: Log in to Emaratax via UAE PASS or your registered FTA credentials.
If you are a first-time user, you need to create an account for registration.
Existing VAT registrants may see partially pre-filled company details.
Step 2: Initiate corporate tax registration: Access the corporate tax section within your dashboard and click on the “Register” option.
The system will prompt you to specify whether the entity type is mainland, free zone, or offshore branch.
Step 3: Enter entity details: Submit your registered name, trade license details, incorporation date, business activities, and financial year-end date. Please ensure consistency with official trade license records.
Step 4: Attach required documents: the system will prompt you to upload supporting documents throughout the registration process. Make sure all files are properly scanned, readable, and do not exceed 15 MB in size.
Step 5: Final review and submission: validate all information is accurate and complete before submitting the corporate tax registration application. Once submitted, you can monitor the application status via the Emaratax dashboard.
Step 6: Get your CTRN certificate: once your application is approved, the FTA issues a corporate tax registration certificate along with a 15-digit CTRN.
Note: VAT registration is distinct from corporate tax registration. Holding a VAT TRN does not exempt a business from completing corporate tax registration separately.

Frequent issues in UAE corporate tax registration & compliance
We have defined the procedure for the corporate tax registration process; businesses may still experience compliance issues if proper groundwork is not completed in advance.
- Inaccurate documentation: Outdated or incorrect documents may lead to processing delays or application rejection from the UAE FTA. Verifying all the required documents before submission helps to avoid rework or rejection.
- Gaps in internal reporting: In the absence of structured tax and accounting processes, businesses may struggle to face challenges in meeting corporate tax obligations. Establishing a robust compliance structure is key to maintaining compliance.
- System entry error on Emaratax: Manual data entry mistakes( license number, dates, or entity type selection) may result in application rejection or resubmission requirements.
- Unclear financial year configuration: Misunderstanding of the financial year end may affect corporate tax filing deadlines and compliance timeliness.
- Delayed registration due to late awareness: Some businesses delay corporate tax registration due to a lack of awareness of deadlines, which may result in penalties and non-compliance risks.
- Insufficient understanding of free zone or mainland rules: Incorrect entity selection during corporate tax registration may lead to incorrect registration classification or filing errors.
What Businesses Must Do After Corporate Tax Registration in the UAE
Receiving the Tax registration Number is the first corporate tax obligation.
Tax-registered businesses must continue to comply with corporate tax filing and payment requirements.
- Corporate tax return filing & payment: A business must file a corporate tax return and pay tax liability within 9 months from the end of the financial year.
Example
Companies with a 31st December year-end must complete their first filing and payment deadline for 2025 by 30th September 2026.
- Record-keeping requirement: Businesses subject to UAE corporate tax must preserve accounting books, invoices, and accurate financial records for at least 7 years.
Ensure that companies subject their financial statements to IFRS.
Entities with turnover below AED 50 million may rely on unaudited financial statements, while businesses exceeding this threshold are required to maintain audited accounts.
- Relief for Small Businesses under UAE Corporate Tax: Qualifying mainland businesses with annual revenue not exceeding AED 3 million may opt for small business relief for the tax period ending on or before 31 December 2026. Under the small business relief regime, eligible businesses are treated as having no taxable income for the relevant tax period, effectively resulting in 0% corporate tax.
- Updating your UAE corporate tax registration: Businesses must notify FTA of any changes to their registered information through Emaratax, including changes to address, ownership structure, authorized signature, or business activities. Failure to submit such information within prescribed timelines may result in an AED 1000 administrative penalty per violation.
