Missing a statutory deadline rarely happens because a founder doesn't care. It happens because no one mapped the year. Here's the calendar we give every FilingSetu client, so the dates find you instead of the other way around.
- Three monthly anchors: GSTR-1 (11th), GSTR-3B (20th), TDS deposit (7th).
- Quarterly: TDS returns and advance-tax instalments.
- Annual: income tax return, GSTR-9 and ROC filings (AOC-4, MGT-7).
- Map the year once and compliance becomes a routine, not a fire drill.
Indian businesses juggle four overlapping compliance streams, GST, TDS, income tax and ROC, each with its own rhythm. Treated separately, they feel relentless. Mapped together onto one calendar, they become a predictable monthly routine. Let's walk through the year.
Start with the monthly anchors
Three obligations repeat every single month, and getting them on autopilot removes most of the stress:
- GSTR-1: outward supplies, due by the 11th of the following month.
- GSTR-3B: summary return and tax payment, due by the 20th.
- TDS deposit: tax deducted must be paid by the 7th of the next month.
“If you only automate three things this year, make it your monthly GST and TDS deposits. Everything else is quarterly or annual, and far easier to plan around.”
Layer in the quarterly checkpoints
Quarters are where TDS returns and advance tax live. Block these four dates now:
- TDS returns (Form 24Q/26Q): by the 31st of the month following each quarter.
- Advance tax: 15% by Jun 15, 45% by Sep 15, 75% by Dec 15, 100% by Mar 15.
- Form 16A issuance to deductees, within 15 days of filing the TDS return.
- Board meeting minutes, if you're a private limited company.
Mark the annual milestones
Finally, the once-a-year filings that close out your compliance, the ones worth starting early so they never become a March scramble:
- Income tax return: typically due Jul 31 (non-audit) or Oct 31 (audit cases).
- GST annual return (GSTR-9): by Dec 31 of the following financial year.
- ROC filings: AOC-4 and MGT-7 within 30 and 60 days of your AGM.

Frequently asked questions
What is the single most-missed deadline?
Advance tax instalments — because income is often lumpy. Underpaying triggers interest under sections 234B and 234C.
Do dormant companies still have deadlines?
Yes. ROC annual filings and the ITR are due even with no activity. See our annual ROC compliance guide.
How do I keep track of all these dates?
Map them once onto a calendar, or use our due-date calendar and let reminders find you.
Print it, pin it, or better yet, hand the whole thing to an Expert who tracks it for you. That's exactly what a FilingSetu compliance plan does: every date above, monitored and filed on time, with a reminder before each one.
