How to File GSTR-1 in India (2026): A Simple Guide
What GSTR-1 is, what it contains, when it is due and how to file it easily — a plain-language guide for Indian businesses.
GSTR-1 is the return where you report your outward supplies (sales) for the period. File it accurately and on time and your buyers get their input credit and your books stay clean. Here is how it works. This is general information, not tax advice — GST rules, rates and thresholds change and vary by case, so confirm specifics with a qualified professional or the official GST portal.
What GSTR-1 contains
It reports your B2B and B2C sales, credit/debit notes, exports and HSN summary for the period. The detail comes straight from your sales invoices.
When it is due
GSTR-1 is filed monthly or quarterly depending on your turnover and the scheme you have opted into (such as QRMP). Check your filing frequency on the GST portal.
The painless way to file
If your billing software captures GST correctly on every invoice, GSTR-1 is just an export. MyGroce keeps GSTR-1-ready reports — B2B, B2C and HSN summaries — so you upload rather than re-key data.
