GST Returns (GSTR)
Periodic filings that report a business's sales, purchases, and tax liability under GST, most commonly GSTR-1 for outward supplies and GSTR-3B for the summary tax payment.
In short
- GSTR-1 reports sales in detail; GSTR-3B is the summary return where tax is actually computed and paid.
- GSTR-2B, auto-generated from suppliers' GSTR-1 filings, is what determines your eligible input tax credit.
- Filing frequency, monthly or quarterly, depends on turnover and whether you've opted into the QRMP scheme.
GST compliance runs through several distinct return forms rather than one filing. GSTR-1 reports outward supplies (sales) for the period in detail, invoice by invoice for B2B transactions. GSTR-3B is a summary return where the actual tax liability is computed and paid, netting output tax against eligible input tax credit. GSTR-2B is an auto-generated statement of eligible ITC based on what suppliers have reported in their own GSTR-1, used to reconcile purchases.
Filing frequency, monthly or quarterly, depends on turnover and the scheme a business has opted into. Consistently late or mismatched returns are one of the most common triggers for GST notices, since the department's systems increasingly cross-check GSTR-1, GSTR-3B, and GSTR-2B against each other automatically. A full breakdown of every return type, including the QRMP quarterly option and the annual GSTR-9/9C filings, is in our overview of GST returns.

Frequently asked questions
What's the difference between GSTR-1 and GSTR-3B?
GSTR-1 reports your sales invoice by invoice. GSTR-3B is where you actually compute and pay tax, netting output tax against eligible input tax credit.
Do all GST-registered businesses file the same returns?
No. Composition scheme taxpayers file CMP-08 and GSTR-4 instead, and regular taxpayers with turnover up to ₹5 crore can opt into quarterly filing under the QRMP scheme.
Is there an annual GST return too?
Yes, GSTR-9, which most regular taxpayers file once a year on top of the monthly or quarterly cycle, and GSTR-9C for taxpayers above ₹5 crore turnover.
