India: GST and GSTR reports

Applies to businesses whose country is India. OneBooks records GST on every document and prepares GSTR-1 (outward supplies) and GSTR-3B (summary return) in the statutory formats, with readiness checks before you file.

What is set up for you

• Currency INR, tax name GST, default rate 18%, tax-exclusive pricing.
• Your state (chosen at sign-up) decides your GSTIN prefix and whether a sale is intra-state (CGST + SGST) or inter-state (IGST).
• GSTR Reports under Reports.

Master data

• Business GSTIN — Settings → Business Profile → Tax ID.
• Customers and suppliers — enter their GSTIN in the tax ID field. Registered customers appear in the B2B section of GSTR-1; unregistered ones in B2C.

• Items — enter the HSN / SAC code; it feeds the HSN summary of GSTR-1. See Items catalog.
• Tax rates — add the slabs you use (0%, 5%, 12%, 18%, 28%) under Settings → Tax Settings.

On documents

• Place of supply — the state code on each invoice and purchase. When it equals your state, the tax splits into CGST and SGST on the reports; otherwise it is IGST. The ledger always posts one combined GST amount; the split is made when the reports are generated.
• Reverse charge (RCM) — on purchases from unregistered or notified suppliers, switch on Reverse Charge; the tax is self-assessed and appears in GSTR-3B’s inward RCM section.
• Supplier GSTIN on purchases feeds input-tax reporting.

Prepare the returns

1. Open Reports → GSTR Reports and choose the period.
2. Check readiness: OneBooks lists errors (missing GSTINs, HSN codes or places of supply) and warnings to fix before filing.
3. Review GSTR-1 (Outward) — B2B invoices, B2CL, B2CS summary, credit/debit notes and the HSN summary with totals for taxable value, IGST and CGST+SGST.
4. Review GSTR-3B (Summary) — outward supplies, inward RCM supplies and input tax credit.
5. Export as JSON for the GST portal’s offline tool, or Excel for your accountant.
