Are these GST guides free?

Yes. All guides on BillRaja are free to read, with no sign-up required. They cover GSTR-3B, GSTR-1, e-invoicing, GST rates, ITC and more.

How current is the information?

Each guide shows its last-updated date, but GST rules can change. The principal rate structure changed for most supplies on 22 September 2025. Always verify rates, thresholds and effective dates on official GST sources or with a CA.

Does BillRaja help with GST filing?

BillRaja generates GSTR-3B-ready summaries from your invoice data and supports CGST/SGST/IGST plus HSN/SAC fields. It does not determine the legally applicable rate or file returns directly; verify the tax details, export the data and file on the GST portal.
