The UAE introduced corporate tax in June 2023, marking a significant change for businesses in the country. Under this new system, companies must file their corporate tax returns every year, within nine months after their financial year ends. For example, if your business follows the January–December financial year, your first tax return deadline will be 30 September 2025. It’s also crucial to be aware of the corporate tax registration deadline UAE has set for new and existing businesses. Timely registration ensures your company is recognized by the FTA and avoids penalties for non-compliance.
