Compliance Calendar July 2026

July opens with key tax deposits and GST return filings, followed by employee contribution payments and quarterly compliance requirements for eligible taxpayers. As the month progresses, businesses will also need to complete GSTR-3B filings based on their filing category before closing the month with the Income Tax Return (ITR) due date for applicable non-audit taxpayers. The month begins with the deposit of TDS and TCS, followed by GSTR-1 and the Invoice Furnishing Facility (IFF) for eligible QRMP taxpayers. EPF and ESIC contributions are due by mid-July, while Composition Scheme taxpayers are required to file CMP-08 for the April–June 2026 quarter. Regular and QRMP taxpayers must also complete their respective GSTR-3B filings before the due date for filing the Income Tax Return (ITR) for FY 2025–26 (AY 2026–27), subject to any extension announced by the CBDT. One notable feature of July is that it includes both monthly and quarterly filing obligations, along with the Income Tax Return (ITR) due date for eligible non-audit taxpayers, making it a month with responsibilities spread right through to the final week.
