Overview

What is a Self-Invoice?

A self-invoice is issued by a registered buyer to themselves when receiving goods or services from an unregistered supplier in a reverse-charge transaction. Section 31(3)(f) of the CGST Act requires the recipient to issue this invoice on the date of receipt — because the unregistered supplier cannot issue a tax invoice.

The self-invoice is the document that supports the buyer's ITC claim on the RCM tax. Without a self-invoice, no ITC is available on RCM tax deposited — so issuing it is not optional.

It is similar in form to a tax invoice but the supplier and recipient blocks both contain the buyer's details (with the unregistered supplier in a separate 'Vendor' block), and it carries the reverse-charge declaration. It is not reported in GSTR-1; the corresponding ITC is claimed in Table 4(A)(3) of GSTR-3B.

Use Cases

When to issue a Self-Invoice

  • Purchases of notified RCM goods/services from unregistered suppliers (legal services, GTA, security services, sponsorship, etc.).
  • Import of services from a foreign supplier (which is treated as RCM).
  • Whenever you are paying GST under RCM and intend to claim ITC.
  • Director's remuneration / sitting fees (RCM for companies).

FAQ

Frequently asked questions

Everything you need to know about self-invoice generation.

Why do I need a self-invoice if I already issued a payment voucher?+

The payment voucher records the payment to the supplier; the self-invoice is the tax-invoice equivalent that supports your ITC claim. Both are needed under RCM — they're two halves of the same transaction.

Can I claim ITC without a self-invoice?+

No. ITC on RCM tax is only available if the recipient has issued a self-invoice for the supply. Skipping it forfeits the credit, even if you have paid the GST.

When should the self-invoice be dated?+

On the date of receipt of the goods or services — Section 31(3)(f) is clear that it must be issued at the time of receipt.

Is a self-invoice reported in GSTR-1?+

No. It is not an outward supply. The RCM output tax is reported in GSTR-3B Table 3.1(d), and the matching ITC is claimed in GSTR-3B Table 4(A)(3).

Does it apply to registered supplier RCM cases too?+

No — when the supplier is registered, they issue a tax invoice mentioning "tax payable under reverse charge" and the buyer does not need a self-invoice. Self-invoice is only for unregistered-supplier RCM.

Can I issue a single consolidated self-invoice for the month?+

Yes. For multiple unregistered RCM purchases in a month, you can issue one consolidated self-invoice at month-end covering all such supplies — provided each vendor is listed separately.

Switched from Zoho last month — haven't looked back. ZapInvoice handles the CGST/SGST split automatically based on my client's state. My CA was actually impressed by the format.

Had a cross-state client situation I was calculating wrong for months. ZapInvoice just switches to IGST automatically — no more manual guessing, no more wrong invoices.

The UPI QR on every invoice is genuinely brilliant. Clients scan and pay the same day. I bill 15+ clients a month — the Pro plan pays for itself in one saved follow-up call.
