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.

Automated reminders

Automate your compliance workflow - never a stale calendar.

Coraa keeps every deadline on track, and runs the engagement procedures the deadline implies.

Beyond the calendar

Run the engagement, meet deadlines, defensibly.

On dates and sources
Dates here follow the standard statutory timeline as of May 2026. 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.
