How to use this

From the page to a working for your team.

Three practical uses:

  • Filter to your category (e.g. GST only, or Statutory Audit only) and click Add to Calendar (.ics). Imports into Google Calendar, Outlook, Apple Calendar. Each deadline becomes an all-day event you can subscribe your team to.
  • Search by form name or section (e.g. “3CD”, “DPT-3”, “Section 44AB”) to scope the filing universe down to one filing’s timeline.
  • Use it as the partner-level master list for the firm — re-run the export every quarter as CBDT / MCA notifications adjust specific dates.

And if you’d rather have a system that tracks all of these per-client and notifies you a week before each — that’s the Engagement Setup hub on CORAA. Per-client deadline tracker, partner notifications, due-date dashboards across your engagement portfolio.

On dates and sources
Dates here follow the standard statutory timeline, updated for extensions reported up to 1 October 2026 (tax audit report and audit-case return, DPT-3). CBDT, MCA, CBIC and other regulators frequently extend specific deadlines via notification, and FM Budget changes can move things mid-year. Always verify the latest position on incometax.gov.in, mca.gov.in and gst.gov.in before relying on any date for a filing.
