UAE Corporate Tax Guide 2026: Rates, Registration & Compliance

UAE Corporate Tax Guide 2026: Complete Guide for Businesses

The UAE introduced corporate tax (CT) effective June 1, 2023. This 2026 guide covers everything you need to know — who needs to register, tax rates, exemptions, filing deadlines, and how corporate tax affects free zone companies.

UAE Corporate Tax Rate 2026

The standard UAE corporate tax rate is 9% on taxable income exceeding AED 375,000. Income below this threshold is taxed at 0%. This applies to all businesses registered in the UAE (free zone and mainland) unless they qualify for specific exemptions.

Large multinationals with global revenue exceeding EUR 750 million may be subject to the OECD’s Pillar Two rules with a 15% effective tax rate from 2025 onwards.

Does Corporate Tax Apply to Free Zone Companies?

Yes, but qualifying free zone persons (QFZPs) can benefit from a 0% tax rate on qualifying income if they meet compliance requirements. Non-qualifying income is taxed at the standard 9% rate.

To maintain QFZP status, free zone companies must:

• Have adequate substance in the UAE (office, employees, management)
• Derive qualifying income from eligible activities
• Maintain audited financial statements
• File annual tax returns on time

Who Needs to Register?

All UAE business license holders — free zone and mainland — must register for corporate tax. This includes sole establishments, LLCs, and free zone companies. The Federal Tax Authority (FTA) handles registration.

Corporate Tax Registration Timeline 2026

Registration deadlines depend on the license issuance date. Generally, businesses must register within a specific window after the FTA opens registration for their category. Late registration incurs penalties.

Key Deadlines

• Tax returns due within 9 months of the financial year end
• Payments due on the same date as return filing
• Record keeping required for 7 years
• Transfer pricing documentation required for related party transactions above AED 1 million
