What is GSTR-1?
GSTR-1 is a monthly or quarterly GST return that every registered GST taxpayer must file. It contains details of all outward supplies (sales) made by a business during a given tax period.
In simple terms: every time you sell something and charge GST, that transaction must be reported in GSTR-1.
Who Needs to File GSTR-1?
Every GST-registered business must file GSTR-1, except:
- Businesses under the Composition Scheme
- Input Service Distributors (ISD)
- Non-Resident Taxable Persons
Monthly vs. Quarterly Filing
The filing frequency depends on your annual turnover:
- Monthly – If your turnover exceeds ₹5 crore
- Quarterly (QRMP scheme) – If your turnover is up to ₹5 crore
What Information Goes Into GSTR-1?
GSTR-1 captures your outward supply details across several tables:
- B2B invoices – Invoices raised to other registered businesses
- B2C invoices – Invoices raised to end consumers
- Export invoices – For businesses that export goods or services
- Credit/Debit Notes – Adjustments to earlier invoices
- Advance receipts – Tax collected on advances received
