Overview
June 2026 is a crucial month for taxpayers, businesses, professionals, and GST-registered entities, with several important compliance deadlines under the Income Tax Act, 1961, Income-tax Act, 2025, and GST laws. Key obligations include TDS/TCS deposits and reporting, issuance of TDS certificates, advance tax payment, filing of statements by investment funds, business trusts, securitisation trusts, and various GST returns such as GSTR-1, GSTR-3B, GSTR-5, GSTR-6, GSTR-7 and GSTR-8.
Taxpayers opting for the QRMP scheme must also adhere to specific filing and payment timelines. Timely compliance with these statutory requirements is essential to avoid interest, penalties, and disruptions in tax credits while ensuring smooth regulatory adherence.
