Types of Invoices under GST

There are 2 types of invoices under the new regime: a tax invoice and a bill of supply. Let us now examine the differences between them:

* Tax invoice

* Bill of supply

Tax Invoice

A supplier who has been registered must issue a tax invoice when he is supplying taxable goods or services. There are specific rules related to the use and the contents of the invoice:

1. A serial number of the invoice:

Serial numbers are consecutive and they consist of letters, special characters, numbers, or any combination, therefore, they are unique for every financial year.

2. Billing and Shipping Address:

This information is required as they will ultimately determine the Place of Supply and the taxation of such transaction accordingly.

3. GSTIN/unique ID:

For the receiver, a GST identification number is required. There are certain specified codes for embassies, UN bodies, or any other class of person so notified.

4.HSN code/accounting code:

The person who has been notified must include an HSN code for the goods and an accounting code for the services supplied.

Bill of Supply

A supplier who is registered will issue a bill of supply when:

1. The goods or services that have been supplied are exempt.

2. The supplier has opted to pay taxes under the Composition Scheme.

The bill of supply is  governed by many rules and according to them, it must contain the following details:

1. Serial number:

The serial number must be a consecutive number that consists of letters and/or numbers and it should also be unique for one financial year.

2. Details of the receiver:

Provide the name, address, and GSTIN/unique ID of the receiver only if the receiver is registered.

3. Particulars of goods:

For the supply value of goods or services, the term “value” is used instead of “taxable value,” as in the tax invoice.

If the value of goods or services that have been supplied is less than Rs 200, then it is not needed to issue a bill of supply.

Time limits for issuing the  Invoicing under GST:

1. Supply of goods:

In the case where the supply involves the movement of goods, then the registered person should issue an Invoicing under GST at the time of removal of goods so that they can be supplied to the recipient. In other cases where there is no movement of goods, the invoice should be at the time when the goods are delivered or they are made available to the recipient.

2. Supply of services:

The tax invoice must be issued within 30 days after the date of completion of services unless the transaction involves banks or financial institutions, in that case, the invoice should be issued within 45 days of completion of services.

3. Receipt voucher:

A receipt voucher or other prescribed documents should be issued as an advance receipt on the supply of goods or services.

4. Reverse charge mechanism:

If a person who has not been registered, supplies goods and services, then the registered receiver should issue an invoice on the date of receipt of goods or services. In this case, the recipient, not the supplier, is liable for the payment of tax.

5. Continuous supply of goods:

When goods and services are supplied, and payment is made, regularly, then the registered supplier must issue an invoice along with each such statement or payment.
