Self-invoicing is a critical compliance requirement under GST for Reverse Charge Mechanism (RCM) transactions and purchases from unregistered vendors. This article provides a comprehensive guide on when, why, and how to issue self-invoices.
What Is a Self-Invoice?
A self-invoice is an invoice issued by the recipient of goods or services instead of the supplier. Under Section 31(3)(f) of the CGST Act, a registered person is required to issue a self-invoice in certain situations.
When Is a Self-Invoice Required?

When a registered person receives goods or services that are notified for RCM, they must issue a self-invoice.
Examples:
- Legal services from an advocate
- GTA services
- Director's remuneration
- Import of services
2. Purchases from Unregistered Persons
When a registered person purchases from an unregistered person, and the supply falls under RCM, a self-invoice must be issued.
Important: Section 9(4) RCM from unregistered persons applies only to specified categories.
