How To Register For Corporate Tax In The UAE: A Quick Guide

The United Arab Emirates has taken a significant step in its economic evolution by introducing a federal Corporate Tax on business profits. Effective for financial years starting on or after June 1, 2023, this new regime implements a two-tiered structure: a 0% tax rate applies to profits up to AED 375,000, and a 9% standard rate for taxable income that exceeds this threshold.

For nearly all businesses operating in the UAE, including those in Free Zones, navigating this shift means prioritizing compliance. The first and most critical action is official registration with the Federal Tax Authority (FTA). Completing this step on time is essential not only to avoid administrative penalties but also to ensure your business maintains its legal standing and credibility in the market.

Let’s dive in and explore exactly how to register for corporate tax in the UAE.

Who Needs to Complete Corporate Tax Registration?

The mandate to register for Corporate Tax is broad, covering virtually all entities operating within the UAE. It is essential to understand your entity’s classification to ensure you meet the Corporate tax registration deadline UAE.

In simple terms, any person (juridical or natural) considered a ‘Taxable Person’ under the new law must register with the FTA, regardless of whether their income falls under the 0% or 9% bracket. This includes:

1. Mainland Companies

All businesses licensed and operating on the UAE mainland, such as Limited Liability Companies (LLCs), Public Joint Stock Companies (PJSCs), and sole establishments (if the turnover threshold is met by the natural person), are classified as resident juridical persons and are subject to mandatory Federal Tax Authority corporate tax registration.

As you identify your corporate tax status, it is the perfect time to audit your overall tax footprint by reviewing the VAT registration requirement in UAE to ensure your business meets every mandatory threshold.

2. Free Zone Entities (The Critical Distinction)

Corporate tax registration for Free Zone companies UAE is mandatory, even if you anticipate qualifying for the 0% tax rate.

• Registration is NOT Optional: Any company registered or incorporated in a UAE Free Zone must register on the EmaraTax corporate tax registration UAE portal to obtain a Corporate Tax Registration Number (CTRN).
• The ‘Qualifying Income’ Rule: To benefit from the 0% tax rate, the Free Zone entity must meet strict criteria to be classified as a “Qualifying Free Zone Person.” This includes maintaining adequate substance, deriving ‘Qualifying Income,’ and adhering to the de minimis requirements. Failure to register or comply with these rules can result in the entire income being taxed at the standard 9% rate.

3. Foreign Businesses with UAE Operations

Non-resident juridical persons (foreign companies) may also be required to register if they have a sufficient presence or source of income in the UAE:

• Permanent Establishment (PE): If the foreign company has a fixed or permanent place of business in the UAE (e.g., a local branch or office) through which it conducts business, it is subject to Corporate Tax and must complete the registration.
• Taxable Nexus: Non-resident entities that earn income from immovable property in the UAE are also deemed to have a taxable nexus and must register. It is also important for these entities to understand how VAT on commercial property in UAE may impact their overall tax liability and cash flow.

The key message remains clear: determining how to register for corporate tax in the UAE and securing a CTRN is a universal obligation for compliant businesses.

Registration Requirements and Mandatory Deadlines

The process of how to register for corporate tax in the UAE is governed by clear guidelines and crucial deadlines set by the Federal Tax Authority (FTA). Missing these dates can result in an administrative penalty of AED 10,000 under Cabinet Decision No. 10 of 2024.

Step 2: Filling Out the Corporate Tax Registration Form

The application is broken down into several sections to ensure accuracy. You must complete all mandatory fields to proceed:

• Entity Details: Select the appropriate Entity Type (e.g., Legal Person – UAE Private Company, Qualifying Free Zone Person). This selection dictates the subsequent information required.
• Identification Details: Provide your main trade license details, including the number and trade name. Here, you must also add all business activities listed on your license and details of all owners/shareholders with 25% or more ownership.
• Contact Details: Enter the official registered address, contact number, and email address for FTA communication.

Receiving Your Corporate Tax Registration Number (CTRN)

Upon successful approval, the FTA will notify you via email and update your EmaraTax dashboard. Your business will be assigned a unique Tax Registration Number (TRN), which is the official identifier for your entity across all tax regimes (VAT, Excise, and Corporate Tax). This number is the equivalent of a TIN (Tax Identification Number) used in many other jurisdictions and is crucial for all future tax filings.

Compliance Obligations After Registration

Obtaining your Corporate Tax Registration Number (CTRN) is just the start. The ongoing compliance obligations are crucial for maintaining good standing with the Federal Tax Authority (FTA) under the Corporate Tax Law UAE (Federal Decree-Law No. 47). 

Managing your fiscal health requires a holistic approach; while you master corporate filings, ensuring you know how to file VAT in the UAE is equally vital for maintaining a clean compliance record with the FTA.

Filing Corporate Tax Returns

• Self-Assessment: UAE Corporate Tax is based on a self-assessment system, meaning the business is responsible for accurately calculating its own Taxable Income.
• Filing Deadline: Businesses must file a single annual Corporate Tax return and pay any tax due within nine months from the end of their relevant Tax Period (financial year). For example, if your financial year ends on December 31, 2024, your filing deadline is September 30, 2025. This entire process is completed via the EmaraTax corporate tax registration UAE portal.

Maintaining Financial Records

• Mandatory Record-Keeping: You are required to maintain all accounting records, financial statements, and supporting documentation for a minimum of seven (7) years following the end of the relevant Tax Period.
• IFRS Standards: Financial statements must be prepared according to International Financial Reporting Standards (IFRS) or relevant local accounting standards.

Penalties for Late Registration or Non-Compliance

The FTA enforces a strict regime of administrative penalties to ensure compliance.

Violation	Penalty (AED)	Note
Late Corporate Tax Registration	AED 10,000	Imposed if registration is not completed by the Corporate tax registration deadline UAE.
Late Filing of Tax Return	AED 500 per month (for the first 12 months), increasing to AED 1,000 per month thereafter.	Applies even if no tax is due.
Failure to Keep Records	AED 10,000 for the first violation, increasing to AED 20,000 for a repeat offense within 24 months.	Essential for audit readiness.
Late Payment of Tax Due	A monthly penalty of 14% per annum on the unpaid amount, calculated from the day following the payment deadline.	This penalty compounds monthly.

Special Cases and Considerations

The application of Corporate Tax includes specific rules for certain business categories.

Free Zone Companies and Qualifying Income

While Corporate tax registration for Free Zone companies UAE is mandatory, the tax rate applied depends on meeting the criteria for a “Qualifying Free Zone Person” (QFZP):

• 0% Rate: Applied to Qualifying Income, which generally includes income from transactions with other Free Zone persons, or income derived from ‘Qualifying Activities’ (like manufacturing, logistics, or holding activities).
• 9% Rate: Applied to all non-qualifying income (e.g., income from mainland sales of non-qualifying goods) or if the Free Zone person fails to maintain adequate substance.
• De Minimis Rule: A QFZP can lose its 0% status if its non-qualifying revenue exceeds the lower of 5% of total revenue or AED 5 million in a Tax Period.

Small Businesses and Exemptions

To support small enterprises, the UAE has introduced the Small Business Relief (SBR):

• Eligibility: Resident businesses (excluding QFZPs) with annual revenue of AED 3 million or less can elect for SBR.
• Benefit: If SBR is elected, the business is treated as having zero Taxable Income for that Tax Period, effectively resulting in 0% tax, simplifying their compliance. This relief is currently available for Tax Periods starting up to December 31, 2026.

Foreign Companies Operating in the UAE

Foreign companies that establish a Permanent Establishment (PE) in the UAE through a local branch or fixed place of business are subject to Corporate Tax on income attributable to that PE and must complete the registration process. Non-resident persons earning income from immovable property in the UAE are also subject to the tax.

Benefits of Timely Registration

The simple act of completing your Federal Tax Authority corporate tax registration by the designated date yields immediate and long-term benefits for your business:

• Avoiding Penalties: The most immediate benefit is avoiding the fixed AED 10,000 penalty for late registration and the subsequent penalties for late filing or payment.
• Legal Compliance: Timely registration ensures your business is fully compliant with the Corporate Tax Law UAE (Federal Decree-Law No. 47), protecting your trade license and preventing legal complications.
• Enhanced Trust with Banks, Investors, and Partners: A valid CTRN demonstrates transparency and serious commitment to compliance. This status is increasingly required by financial institutions for opening bank accounts and is viewed favorably by potential investors and major partners.
• Access to Reliefs: Only registered entities can avail themselves of beneficial tax treatments like the 0% threshold on the first AED 375,000 of profit or Small Business Relief. Beyond simple compliance, understanding the broader corporation tax advantages can help businesses structure their operations more efficiently within the UAE’s evolving economy.
