GST Returns: The Monthly Compliance Calendar Foreign Companies Underestimate
GST compliance isn't a one-time registration, it's a recurring monthly and annual filing calendar with real penalties for missed deadlines, even at zero turnover.
Once GST-registered, a business enters a recurring filing calendar: GSTR-1 (outward supplies) and GSTR-3B (summary return and tax payment) are due monthly for most registered entities, with an annual return (GSTR-9) also required. Filings are due even in months with no transactions, a nil return still needs to be filed, and late filing penalties apply per day of delay regardless of whether tax is actually owed.
Foreign-owned subsidiaries new to India sometimes underestimate this as an ongoing operational commitment rather than a one-time registration event, the monthly filing cadence needs a dedicated internal owner or outsourced accounting relationship from month one, not something set up reactively after the first missed deadline.
Late filing penalties are individually modest but compound with interest and can also affect the entity's GST compliance rating, which in turn can affect vendors' and customers' willingness to transact, since Indian businesses routinely check a counterparty's GST compliance status before extending credit terms.
