Filing GST Returns

The return-filing rhythm

Under GST, compliance is a monthly (or quarterly) rhythm of returns that report your outward supplies, claim input tax credit, and pay net tax. The three returns every regular taxpayer should know are GSTR-1, GSTR-3B and GSTR-9.

GSTR-1 — outward supplies

GSTR-1 reports all your outward supplies (sales) invoice-by-invoice. It is filed monthly (or quarterly under the QRMP scheme). The data you file here auto-populates your buyers' GSTR-2B, so accuracy is critical — your customers' ITC depends on it.

GSTR-3B — summary and payment

GSTR-3B is a self-declared monthly summary of outward supplies, ITC claimed and tax payable. It is where you actually pay the net GST after offsetting ITC. GSTR-3B must reconcile with GSTR-1; mismatches invite notices.

GSTR-9 — annual return

GSTR-9 is the annual return consolidating the year's monthly filings. It is mandatory for taxpayers above a turnover limit and provides a yearly reconciliation. Filing returns on time matters — late filing attracts late fees and interest, and persistent default can block your e-way bills and ITC.
