What is the Bill of Supply under GST?

A Bill of Supply is a business document given by a supplier registered under GST who cannot charge GST on their supplies. It functions as a proof of sale but lacks tax information such as CGST, SGST, or IGST.

Under Section 31(3)(c) of the CGST Act, 2017, every registered person providing exempted goods or services or a composition dealer is obligated to issue a Bill of Supply in place of a tax invoice.

Meaning of Bill of Supply under GST

To put it simply, a Bill of Supply is like a tax invoice but does not include GST. It is issued when:

There is no GST applicable to a particular transaction.

The seller has no legal authority to collect tax from the buyer.

The supplies are either exempt or fall under the composition scheme.

Who Should Issue Bills of Supply?

Due to GST requirements, the following suppliers are required to issue a Bill of Supply:

1. Composition Dealers: Businesses registered under the GST Composition Scheme are not allowed to charge GST on their outward supplies. They pay tax at a fixed rate on turnover. However, they issue Bills of Supply to the customers.

2. Suppliers of Exempted Goods or Services: If a registered person deals with exempted goods/services exclusively (like healthcare, education, agricultural products), such persons must issue a Bill of Supply.

3. Exporters and SEZ Developers (Without GST Charge): Exporters who supply goods/services without charging GST (under LUT/Bond) must issue a Bill of Supply.
