What is Corporate Tax?

The corporate tax law in UAE applies to most juridical persons incorporated in the country, with specific rules for free zone persons and defined cases for non-residents that create a nexus. 

The headline rate is 0% on taxable income up to AED 375,000 and 9% on income above that level, with a 15% domestic minimum top up tax for large multinational groups.

Taxable income starts from accounting profit and is adjusted by law and related decisions. Clean ledgers and documented transactions remain the first control for correct computations and smooth returns.

Who Must Register for Corporate Tax in UAE?

Corporate tax registration in Dubai, UAE is required for:

• UAE-incorporated companies and other juridical persons.
• Free zone entities that plan to claim preferential treatment or that expect non-qualifying income.
• Foreign entities with a permanent establishment or other nexus as defined by guidance.

Important Advice: Branches of a UAE legal entity typically register under the parent. Each group should still map the legal structure before applying so the application reflects the right entity and trade licenses.

When to Register for Corporation Tax?

Deadlines have been set by the FTA across legal forms and incorporation periods. Practical timing for applicants falls into two buckets:

New incorporations. Register soon after the trade license is issued and the accounting year is set.
