The introduction of Corporate Tax in the UAE has transformed the financial and compliance landscape for businesses. With the Federal Tax Authority (FTA) actively monitoring compliance, every Chief Financial Officer (CFO) must be fully aware of critical deadlines, filing requirements, and penalties to avoid costly mistakes.
In this blog, we will cover the key corporate tax deadlines in UAE, the compliance calendar, and best practices for CFOs to ensure smooth and timely filing.

1. Corporate Tax Overview in UAE
- Effective Date: Corporate Tax is applicable for financial years starting on or after 1 June 2023.
- Tax Rate:
- 0% on taxable income up to AED 375,000 (to support SMEs).
- 9% on taxable income above AED 375,000.
- Scope: Applies to mainland companies, free zone entities (with certain exemptions), and foreign companies with a permanent establishment in the UAE.
2. Corporate Tax Registration Deadlines
- All taxable businesses must register with the FTA for Corporate Tax.
- Registration deadlines are staggered by the FTA based on the type of entity and license issuance date.

3. Tax Return Filing Deadlines
