GST, Income Tax & Companies Act/LLP Due Dates — Compliance Calendar

Due Today & Next 3 Days

Register of Due Dates

Notes. Dates shown are the standard statutory due dates generally applicable under the GST law, the Income-tax Act and the Companies Act, 2013, as of August 2026. QRMP GSTR-3B dates assume Chhattisgarh’s Group 1 classification (22nd); Group 2 states file by the 24th. Companies Act filings for October–November (ADT-1, AOC-4, MGT-7) assume a 31 March year-end with the AGM held on 30 September — recompute from the actual AGM date for any specific company. DIR-3 KYC is now a triennial filing (once every three financial years, due 30 June) under the Companies (Appointment \u0026 Qualification of Directors) Amendment Rules, 2025, effective 31 March 2026 — it no longer applies to every director every year. Due dates are frequently extended or revised by CBIC/CBDT/MCA notifications; always cross-check against the GST portal, incometax.gov.in and the MCA portal before relying on this calendar for a filing decision. Late fee and penalty figures are the standard statutory rates and are indicative only — amnesty schemes, turnover-slab caps, and case-specific adjudication can change the actual amount payable; verify on the relevant portal before quoting a figure to a client.
