When a Tax Invoice or a Bill of Supply should be Issued?

In some situations, generating a GST invoice as soon as things are dispatched or services are given can be challenging. As a result, the Indian government has established a universal time limit for suppliers to comply with it. But this time frame varies based on the type of goods supplied and they are explained below:

Tax Invoice for Normal Goods

Goods suppliers must create an invoice on or before the date of the products’ disposal. Removal of goods under Section 2 (96) of the CGST Act of 2017 can entail one of two things:

  • The goods have been shipped for delivery to the intended recipient.
  • The recipient or an authorised person acting on the recipient’s behalf collects goods from the provider.

Tax Invoice on Continous Supply Goods

If the invoice is for a customer with whom the supplier has a regular business relationship, those can issue a GST invoice on or before the account statement is generated or payment is received.

Tax Invoice on Services Provided

In the case of a GST invoice bill for services rendered, the bill must be issued within 30 days of the services being rendered.

GST Invoice on Bank and NBFC Services

The date for issuing a GST receipt for financial services provided by banks and other financial institutions is 45 days from the date of service provision.

Copy of GST Invoices for Goods Supply

If a GST invoice for goods supply is issued, the issuer must prepare three copies for the following parties engaged in the transaction:

  • The recipient will receive the original copy.
  • The duplicate copy is for personnel in charge of conveying the items from the supplier to the recipient.
  • The supplier will benefit from the triplicate copy.

Copy of GST Invoices for Services Supply

Since no transporters are engaged in a service provision, issuers only need to print two copies of the GST invoice bill.

  • The service recipient owns the original document.
  • The provider keeps the duplicate for internal usage.

Revising Invoices Issued Before GST

Revised tax invoices can be raised against issued invoices under Rule 53 of the CGST Act, 2017. The modification of the GST invoice bill may result in a decrease or increase in the price of the products or services provided. It could also affect the CGST, SGST, and IGST rates that were previously applied to this bill.

The list of details that needs to be mentioned on revised invoices are listed below:

  • ‘Revised Invoice’ should be written on the bill
  • Supplier’s GSTIN, address, and name should be mentioned
  • Bill issue date
  • A registered recipient’s name, GSTIN/UIN, and address
  • GST invoice’s date and serial number
  • Shipping address and information
  • Serial number that is unique and not exceeding 16 characters
  • The issuer’s or authorised representative’s signature is required

When Tax Invoice is not Mandatory?

A supplier can avoid issuing a GST invoice only under the following two situations:

  • The beneficiary in the transaction is unregistered.
  • When the recipient declares that he or she does not require an invoice of this nature.

Please note that a supplier must meet both of these criteria in order to avoid the legal requirement of producing a GST invoice. Rather, at the conclusion of each day, the registered provider can produce a consolidated tax invoice for all such supplies.
