UAE Corporate Tax Guide 2026: Everything Businesses Need to Know

Comprehensive guide to the UAE 9% corporate tax — who must register, exemptions, free zone benefits, filing deadlines, and compliance tips.

By PS Business UAE Team

What Is UAE Corporate Tax?

The UAE introduced a 9% federal corporate tax effective June 1, 2023. This applies to all businesses with taxable income exceeding AED 375,000. Income below this threshold is taxed at 0%.

Despite this change, the UAE remains one of the lowest-tax jurisdictions globally, and there is still no personal income tax.

Who Must Register?

  • All UAE mainland companies (LLCs, sole establishments, civil companies)
  • Free zone companies (even if qualifying for 0% rate)
  • Foreign companies with a permanent establishment in UAE
  • Individual business owners earning above AED 1 million

Exempt: Government entities, pension funds, qualifying investment funds, natural resource extraction businesses.

Free Zone Tax Benefits

Free zone companies can qualify for 0% corporate tax on qualifying income if they:

  • Maintain adequate substance in the UAE (office, staff, decisions made locally)
  • Earn qualifying income (free zone transactions, international services)
  • Do not earn non-qualifying income from mainland UAE activities
  • Meet transfer pricing requirements
  • Keep audited financial statements

Non-qualifying income (e.g., mainland customer revenue) is taxed at 9%.

Key Deadlines and Penalties

  • Registration: All businesses must register with the Federal Tax Authority (FTA) based on license issuance date
  • Filing: Tax returns due within 9 months of tax period end
  • Payment: Due by the filing deadline

Penalties:

  • Late registration: AED 10,000
  • Late filing: AED 500 first offense, AED 1,000+ repeat
  • Late payment: 2-4% of unpaid tax monthly
