E-Invoice Exempt Transactions: B2C, SEZ Supplies, Nil-Rated and RCM Inward
E-invoicing is not required for B2C consumer invoices, nil-rated or exempted supplies, inward supplies under reverse charge, invoices issued by SEZ units, and non-GST supplies like petroleum and alcohol. It IS required for export invoices, zero-rated LUT supplies, and supplies made by taxable persons to SEZ units and developers.

E-invoicing is not required for B2C consumer invoices, nil-rated or exempted supplies, inward supplies under reverse charge, invoices issued by SEZ units, or non-GST supplies such as petroleum and alcohol. It is required for export invoices (zero-rated, with or without LUT), and for supplies made by taxable persons to SEZ units and developers. The distinction turns on who the recipient is and whether the supply is within GST — not on whether your company is a "covered person."
What the law actually requires
The e-invoice obligation under Rule 48(4) of the CGST Rules 2017 attaches to specific types of supply, not blanketly to a taxpayer. A company covered by the ₹5 crore threshold still does not e-invoice its B2C sales. The framework separates transactions that carry the obligation from those that do not, and the accounts team needs a document-level rule, not a company-level one.
Where e-invoicing is NOT required
Where e-invoicing IS required
The most common misconception is that "zero-rated" or "export" means "exempt." It does not. An export invoice is a B2E document and is squarely within e-invoicing — the export shipping bill and the e-invoice both feed the GST system. Similarly, a supply to an SEZ unit is an "SEZ supply" and is covered even though the SEZ unit issuing its own invoices is excluded. The direction of the supply is the test.
Worked example: Coastal Remedies Pvt Ltd sorts its month
Coastal Remedies Pvt Ltd, a Chennai company above ₹5 crore, issues four kinds of documents in a typical month. Its document-level rule:
Coastal e-invoices INV/0351, INV/0353 and INV/0354, and issues INV/0352 as a normal B2C tax invoice with no IRN. It also receives a service from an unregistered transporter on which it self-assesses GST under reverse charge — that is an inward supply, reported in GSTR-3B Table 4B, with no e-invoice obligation on Coastal's side (the supplier has no GSTIN).
The B2C document is not free of obligation entirely: if Coastal's turnover exceeds ₹500 crore, Notification No. 14/2020-CT requires a dynamic QR code on the B2C invoice. Below that, the B2C invoice carries no IRN and no QR code requirement.
What a director should actually watch
- Build a document-type rule, not a company rule. The test is recipient-based (registered vs unregistered), supply-based (GST vs non-GST), and direction-based (to SEZ vs by SEZ). Train the billing team on all four.
- Never assume exports are exempt. Zero-rated is not exempt. Export invoices need IRNs, and the auto-population into GSTR-1 Table 6A depends on it.
- Check your SEZ classification. SEZ units are excluded; SEZ developers are covered. If you are an SEZ developer, you e-invoice.
- RCM inward supplies still need GSTR-1/GSTR-3B reporting. Being outside e-invoicing does not mean outside return filing — reverse-charge inward supplies are declared in Table 4B of GSTR-3B.
⚠️ — confirm the current exclusion list for SEZ units and the exact wording of the relevant notification before relying on an SEZ exemption. The exclusion operates through the proviso to Rule 48(4) and related notifications, and the developer/unit distinction should be checked against the latest position.
The document-decision checklist
The fastest way to apply the rules is a four-question checklist that the billing team runs for every invoice before it is issued:
The failure mode is a covered supply slipping through as a B2C or "exempt" document because the sales team chose the wrong transaction type at creation. Build the checklist into the billing software — block e-invoice-required documents from being issued without an IRN — rather than relying on a human to remember the supply-type tests at month-end. A document that should have carried an IRN and does not fails Rule 48(5), and the customer's credit is blocked under Section 16(2)(aa).
FAQ
Is an export invoice covered by e-invoicing?
Yes. Exports (zero-rated on LUT or on payment of IGST) are covered. Zero-rated does not mean exempt from the IRN obligation.
Do I e-invoice a sale to an unregistered customer?
No. B2C invoices are outside e-invoicing. Only the ₹500 crore-plus dynamic-QR-code obligation can apply to a B2C invoice.
Is a supply to an SEZ unit covered?
Yes — if you are a taxable person supplying to an SEZ unit or developer, the invoice is covered. The SEZ unit issuing its own invoices is the one excluded.
What about inward supplies under reverse charge?
No e-invoice obligation for the inward RCM supply itself, because there is often no supplier GSTIN. The liability is still declared in GSTR-3B.
Does nil-rated supply need an e-invoice?
No. Nil-rated and exempted supplies are outside the obligation. But confirm the supply genuinely falls under an exemption notification and is not merely zero-rated — exports are zero-rated and ARE covered.
Are petroleum and alcohol covered?
No. They lie outside GST, so no GST e-invoicing applies to them.
Our company is under ₹5 crore but makes exports. Do we e-invoice?
Not until your aggregate turnover crosses the threshold. Below ₹5 crore you are not a covered person, so even exports do not require IRNs — though you remain free to report voluntarily.
