Who is Subject to UAE Corporate Tax?

Corporate Tax applies to the following Taxable Persons:

UAE Companies: All companies and other legal entities incorporated or effectively managed and controlled in the UAE.
Individuals: Individuals who conduct a business or business activity in the UAE, as specified in a Cabinet Decision.
Foreign Entities: Foreign legal entities that have a Permanent Establishment in the UAE or derive State Sourced Income.

The Road to Compliance: A Step-by-Step Guide

Ensuring your business is compliant involves a series of crucial steps. Missing any of these can lead to significant penalties.

1. Corporate Tax Registration

All businesses subject to Corporate Tax must register with the Federal Tax Authority (FTA) to obtain a Tax Registration Number (TRN). This is a mandatory step, regardless of whether your business is expected to have a tax liability.

2. Maintain Audited Financial Statements

Maintaining accurate and comprehensive financial records is the cornerstone of CT compliance. The Corporate Tax Law requires businesses to prepare and maintain audited financial statements that form the basis for calculating taxable income.

3. Understand Taxable Income Calculation

Taxable income is calculated by making adjustments to the accounting net profit (or loss) as reported in the financial statements. These adjustments include:

Non-deductible expenses: Such as certain fines, penalties, and 50% of entertainment expenses.
Exempt income: Including dividends and capital gains from qualifying shareholdings.
Transfer pricing adjustments: Ensuring transactions between related parties are conducted at arm’s length.

4. Filing Your Tax Return

The tax return must be filed electronically with the FTA within 9 months of the end of the relevant tax period. For many businesses, this means the first deadline is September 30, 2025.

Special Considerations: Free Zones and Legislative Updates

Qualifying Free Zone Persons

Businesses established in UAE Free Zones can benefit from a 0% Corporate Tax rate on ‚Qualifying Income ‚as provided they meet specific conditions, including:

Maintaining adequate substance in the Free Zone.
Deriving ‚Qualifying Income as defined in the legislation.
Not having elected to be subject to the standard Corporate Tax rate.

Understanding these nuances is critical for any business operating in a Free Zone.

Latest Legislative Updates

The tax landscape is continuously evolving. In November 2025, the UAE announced **Federal Decree-Law No. 17 of 2025**, which amends the Tax Procedures Law and will come into effect on January 1, 2026. Key changes include a clearer five-year window for tax refund claims and stronger audit powers for the FTA. [4] Staying informed about these changes is essential.
