E-Invoicing Threshold Changes: Finance Team Checklist

Finin2min GST Desk·June 2026·8 min readE-INVOICE

E-invoicing is not a billing-software feature; it is a statutory invoice-control process. Once your business crosses the notified turnover threshold, finance must ensure eligible documents are reported to the Invoice Registration Portal, IRNs are generated, QR codes are carried, and GSTR-1/e-way bill data does not drift away from books.

Who should watch the threshold?

Finance teams should monitor aggregate turnover at PAN level, not merely branch-wise GSTIN turnover. Notification 10/2023-Central Tax implements e-invoicing for taxpayers having aggregate turnover exceeding ₹5 crore from 1 August 2023. That threshold should be checked before year-end, before onboarding new billing software, and whenever a group entity or new GSTIN is added to the invoicing process.

Do not wait for customer disputes. If e-invoicing applies and an eligible B2B/export invoice is issued without IRN, the buyer may challenge the invoice and ITC support. Build the control before the first invoice crosses the workflow.

Use the GST Calculator — Inclusive, Exclusive, CGST, SGST and IGST to work through the related inputs before acting.

Frequently Asked Questions

Is e-invoicing based on GSTIN turnover or PAN-level aggregate turnover? ▼

The notified threshold is linked to aggregate turnover. Finance teams should monitor PAN-level turnover across GSTINs and then apply e-invoicing controls to the relevant registered persons/document flows.

Does e-invoicing replace GSTR-1 filing? ▼

No. E-invoicing helps populate/report invoice data, but return filing and reconciliation controls continue separately.

Should exporters generate e-invoices? ▼

If e-invoicing applies to the registered person and the document type is covered, export invoices must be included in the workflow with the required export endorsement and details.
