This Compliance Calendar for Financial Year 2026–27 has been curated to provide a structured overview of key statutory due dates and regulatory compliances applicable under various laws, including the Income-tax Act, GST laws, and other allied legislations. The objective of this calendar is to assist businesses, professionals, and stakeholders in tracking important compliance timelines and ensuring timely fulfilment of statutory obligations throughout the financial year.

Tax compliance in India continues to evolve with frequent legislative amendments, revised reporting standards, and changing procedural requirements. The Financial Year 2026–27 assumes particular significance with the implementation of the new Income-tax Act, 2025 replacing the Income-tax Act, 1961, along with consequential changes in the Income-tax Rules and the overall compliance framework. 

This Compliance Calendar is intended to serve as a quick and practical reference guide for staying ahead of important statutory deadlines and maintaining timely compliance throughout the year. We hope it assists you in planning, monitoring, and managing your regulatory obligations efficiently and effectively.
