October 2025 Compliance Calendar: GST, TDS, ROC & Labour Law

October 2025 marks the most critical compliance month of FY 2025–26, featuring an unprecedented convergence of statutory obligations that demands strategic planning and meticulous execution. This month brings together four simultaneous pressure points that significantly impact businesses across India:

Executive Summary: October 2025 – Peak Compliance Convergence

  • 🎯 Final Deadline Cluster: October 31 witnesses the convergence of high-stakes filings—ITR for audit cases under Section 139(1) of the Income Tax Act, 1961, and Q2 TDS returns (Forms 24Q/26Q/27Q) as per Section 200(3)—creating audit dependencies that require careful coordination.
  • 📊 Q2 Quarterly Closure: The July–September quarter closing demands meticulous reconciliation across GST (QRMP scheme) under Section 39 of the CGST Act, 2017 and TDS systems, with staggered filing deadlines extending through October 24.
  • 🏢 Post-AGM Corporate Rush: Companies face a compressed 30-day window under Section 137 of the Companies Act, 2013, after September AGMs to file Form AOC-4, placing most due dates between October 29–30.
  • 👤 Director KYC Extension: MCA General Circular No. 04/2025 has extended the DIR-3 KYC filing deadline to October 15, 2025, without a late fee, providing crucial relief to directors.

⚠️ ITR Filing Deadline – Extension Watch

  • Official Position (as of September 30, 2025): As of October 31, 2025, the statutory due date for filing ITR for audit cases (FY 2024–25) remains unchanged, as per the extension from September 30 to October 31, as per the CBDT circular. 14/2025 dated September 25, 2025.
  • Latest Development: Certain High Courts have directed CBDT to extend the ITR due date to November 30, 2025, creating anticipation in the tax community.
  • CBDT Status: No formal notification has been issued yet regarding any further extension beyond October 31.
  • Action Required: Prepare comprehensively for October 31 compliance while monitoring CBDT updates through official channels. If an extension is formally notified, adjust your compliance timeline to November 30 accordingly.
