Pair the calendar with the filing guides
Deadlines are more useful when the form guide is one click away.
When a filing appears on the timeline, the next step is usually to open the matching form page, confirm the filing trigger, and make sure the support documents are in place before the due date arrives.
Typical filing sequence
Most teams move from calendar to form to submission.
1. Spot the due date on the calendar and filter by category.
2. Open the matching form guide to see who files, when, and what it costs.
3. Collect the board approvals, KYC records, statements, or tax data you need.
4. Submit early enough to keep the penalty surface small.
Automated reminders
Turn the timeline into an actual compliance system.
Public calendars are useful for discovery. The real value comes when the dates trigger reminders, document prep, and filing tasks automatically inside your operating dashboard.
How the calendar is organized
MCA
Annual returns, financial filings, director KYC, deposits, share capital filings, and foreign reporting.
GST
Monthly GSTR-1 and GSTR-3B reminders are broken out by filing month for quick review.
TDS
Deposit deadlines, quarterly statements, and TCS due dates are separated so finance teams can batch the work.
IT
Advance tax and return-filing deadlines are included to keep the company and founders aligned on tax planning.
