UAE Corporate Tax Rules 2026: Essential Guide for Businesses

The UAE Federal Tax Authority (FTA) introduced corporate tax in June 2023, creating new compliance obligations for every business operating in Dubai, Abu Dhabi, Sharjah, and across the Emirates. With penalties starting at AED 10,000 for late registration and AED 1,000 per month for late filing, understanding these rules isn't optional — it's essential for business survival.

This guide covers the essential FTA rules every UAE business owner needs to know, with practical examples and clear deadlines to avoid costly penalties.

The FTA's corporate tax rules apply to all business operations across the UAE, from Dubai's financial centers to free zones and mainland establishments

UAE Corporate Tax Rates

The FTA has set simple, tiered tax rates for all UAE businesses:

Annual Taxable Income	Tax Rate	Your Tax Bill
AED 0 - AED 375,000	0%	AED 0
Above AED 375,000	9%	9% of income above AED 375,000

Examples:

• AED 300,000 profit: No tax owed
• AED 500,000 profit: AED 11,250 tax (9% of AED 125,000)
• AED 1,000,000 profit: AED 56,250 tax (9% of AED 625,000)

Free Zone Special Rules

Qualifying Free Zone Persons (QFZPs) may pay 0% tax on qualifying income if they meet all FTA conditions:

• Adequate substance in the UAE
• Qualifying income only (per Cabinet Decision No. 55)
