GSTR-1 Explained: What It Is and How to File It

GSTR-1 is one of the key GST returns used by registered taxpayers to report details of outward supplies.

The information reported in GSTR-1 is important because it can affect the GST records and input tax credit visibility of customers.

What is reported in GSTR-1?

Depending on the taxpayer and transactions, GSTR-1 can contain information relating to:

• Business-to-business invoices
• Business-to-consumer supplies
• Credit notes
• Debit notes
• Export supplies
• Amendments
• HSN/SAC-related information

Why is accurate GSTR-1 filing important?

An incorrect invoice number, GSTIN, taxable value or tax amount can create reconciliation problems for the customer.

Businesses should therefore review their sales register before submitting GSTR-1.

GSTR-1 preparation process

A typical process involves:

1. Collect sales invoices.
2. Verify customer GSTINs.
3. Check invoice numbers.
4. Verify taxable values.
5. Check applicable tax rates.
6. Review credit and debit notes.
7. Upload or enter the required information.
8. Validate the return.
9. Submit and file it.

For quarterly taxpayers under the QRMP framework, the GST Portal also provides the Invoice Furnishing Facility (IFF) for eligible taxpayers.
