Who needs to issue e-invoices
Under GST e-invoicing, a business reports each B2B invoice, credit note and debit note to the Invoice Registration Portal (IRP) and gets back an Invoice Reference Number (IRN) and a signed QR code. Without the IRN, where e-invoicing applies, the document is generally not treated as a valid tax invoice. Applicability depends on three things:
- Turnover: aggregate turnover above ₹5 crore in any financial year from 2017-18 onwards (threshold applicable since 1 August 2023).
- Entity type: some categories are exempt whatever their turnover.
- Type of supply: B2B supplies and exports are covered; B2C supplies are not.
The test in one line
E-invoicing is likely applicable if: highest AATO from 2017-18 > ₹5 crore and the entity is not exempt and you make B2B supplies or exports.
Example (illustrative)
A Ludhiana fastener manufacturer had turnover of ₹4.6 crore in 2022-23 and ₹5.4 crore in 2024-25, selling to dealers who hold GSTINs. Because turnover exceeded ₹5 crore in a financial year, e-invoicing is likely to apply from the following year for its B2B invoices. Its occasional sales to walk-in customers remain ordinary B2C invoices.
Common mistakes
- Looking only at the current year. The test uses the highest turnover in any financial year from 2017-18.
- Counting one GSTIN only. Aggregate turnover covers all GSTINs under the same PAN across India.
- Assuming an SEZ developer is exempt. The exemption is for SEZ units.
- Reporting late. Taxpayers at ₹10 crore and above generally have 30 days from the invoice date.
Check the current rules on the e-invoice portal and the GST portal. E-Way Easy is not a government portal and does not generate IRNs.
