Difference between Tax Invoice and Bill of Supply


  Tax Invoice 

            Generally speaking, an invoice is a commercial instrument issued by a seller to a buyer. It identifies both the trading parties and lists, describes, and quantifies the items sold, shows the date of shipment and mode of transport, prices and discounts, if any, and delivery and payment terms. In certain cases, (especially when it is signed by the seller or seller’s agent), an invoice serves as a demand for payment and becomes a document of title when paid in full.

Under the GST regime, an “invoice” or “tax invoice” means the tax invoice referred to in section 31 of the CGST Act, 2017. This section mandates issuance of invoice for every supply of goods or services

The invoice should contain description, quantity and value & such other prescribed particulars (in case of supply of goods) and the description and value & such other prescribed particulars (in case of supply of services). An invoice need not be issued if the value of the supply is less than Rs. 200/- subject to specified conditions.

      Bill of Supply      

A business registered under GST issues a tax invoice to the buyer. Such an invoice mentions the GST rate charged on the goods and services sold.

However, some businesses even though registered under GST cannot charge any tax on the invoice issued by them. Such dealers have to issue a Bill of Supply. A Bill of Supply is issued when GST is not applicable on a transaction or when GST is not to be recovered from the customer.

A bill of supply is similar to a GST invoice except for that bill of supply does not contain any tax amount as the seller cannot charge GST to the buyer.

A bill of supply is issued in cases where tax cannot be charged:

  1. Registered person is selling exempted goods/services,
  2. Registered person has opted for composition scheme,
  3. An exporter is also not required to charge GST on their invoice.
