What is a GST Tax Invoice and How it Works?

A GST tax invoice is a document that a registered person issues to another registered person for the supply of taxable goods or services. It contains all the relevant information about the transaction, such as the GSTIN of the supplier, the GSTIN of the recipient, the value of the supply, the GST rate, and the amount of GST payable.

Let's see cases when a GST invoice can be either a tax invoice or a bill of supply. A registered supplier for taxable supplies issues a tax invoice. A registered supplier issues a bill of supply for exempt supplies, zero-rated supplies, and supplies to an SEZ unit or an SEZ Developer.

Types of GST Invoices

Tax Invoice

A tax Invoice under GST acts as a legal document and proof of tax charged. The document is also important for a registered person or company to claim ITC benefits. The document shared acts as a payment term between the seller and the buyer and benefits both equally.

Bill of Supply

The GST section of the law has several clauses that affect the tax chargeable on different sales. Taxes cannot be charged by a supplier of goods and services in some instances. In this case, instead of a Tax Invoice, the seller or buyer must generate a Bill of Supply.

Here are 2 cases in which a Bill of Supply we should issue:

  1. Suppliers who deal in goods or services that are exempt from GST.
  2. Rather than using the "Regular Scheme", the GST-registered supplier intends to use the "Composition Scheme".

According to this case, since the buyer is not paying any GST, they will not be able to claim Input Tax Credit. Also, make sure to use the title "Bill of Supply".

Invoice and Bill of Supply (Combined)

Suppliers can sell both, so they are not required to sell GST-applicable products or opt for GST-exempt products. In that case, the GST system of India issues a notification on 24.04.2022. It states that the supplier can generate an invoice that includes all goods and services. A tax invoice and a bill of supply will be combined in this invoice. It is called "Invoice-Cum-Bill-of-Supply" for this reason.

Receipt Voucher

Receipt Vouchers are generated against payments. This serves as proof of payment. This comes into the act when a supplier receives an advance on payment by a buyer. Rather than generating a Tax invoice, a receipt voucher works the best.

Refund Voucher

In some cases, a supplier cannot provide the goods and services ordered by the buyer. If the supplier has already received an advance payment for the supply but fails to fulfil the order, they must issue a refund voucher. The voucher serves as proof of the refund.

Payment Voucher

Suppliers are sometimes not GST registered, but buyers are. In cases where the buyer receives goods and services subject to "Reverse-Charge", the buyer must generate a payment voucher for the supplier.

Debit and Credit Note

In some cases, the supplier has to supply and simultaneously return some of the payment. In the case of discounts or a sudden decrease in the price of goods or services, this can cause. In the event of a return, the supplier may also be required to refund the amount. The supplier must issue a credit note in such cases. The note will also serve as proof of reduced tax and assist in understanding the variation in chargeable tax. An invoice must be debited if the supplier has mentioned a lower chargeable amount by mistake or in any other circumstance. In other words, this debit is not a token demanding the remainder of the invoice to meet the correct price. In order to maximize the supplier's tax liability, GST debit notes must be shown in the GST return. Registered suppliers generate supplementary tax invoices if they charge the wrong tax amount by mistake. Using an additional tax invoice in the form of a credit or debit note, the tax amount in excess or less can be matched to the correct amount.
