What is GSTR-1?
GSTR-1 is a monthly or quarterly return that needs to be filed by registered taxpayers under GST. It contains details of all outward supplies of goods and services made during a tax period. This includes sales invoices, debit notes, credit notes, and revised invoices.
The return is critical for the GST ecosystem as the details filed in GSTR-1 by a supplier are made available to the recipient in their GSTR-2A, which they can use to claim input tax credit.
Who Should File GSTR-1?
All registered taxpayers under GST are required to file GSTR-1, except:
- Input Service Distributors (ISD)
- Composition dealers
- Non-resident taxable persons
- Persons liable to deduct or collect TDS/TCS
