Miss one GST date and the damage is rarely the late fee itself — it is the blocked input tax credit, the vendor follow-ups, and the diligence red flag two years later when an investor's lawyer asks why GSTR-3B for March was filed in June. Most founders don't need more tax knowledge; they need a boring, repeatable calendar.
The four dates that actually matter
- 7th — TDS deposited for the previous month
- 11th — GSTR-1: outward supplies (your sales invoices)
A compliance calendar is a product feature. Your customers just never see it working — only failing.
