Introduction
The seller issues a commercial instrument invoice to the buyer during a supply transaction. The invoice is an official request for the money to be paid to the supplier. It is also a valid document proof of the supply transaction. The invoice contains details about all the parties involved in the transaction and the description and quantity of items sold. It will also include discounts and other specific payment terms. The supplier also lists delivery details in the invoice. In India’s GST system, one document reigns supreme: the tax invoice. Acting as a crucial gateway for buyers to claim the Input Tax Credit (ITC), it also guarantees suppliers their rightful payment. Under the GST regime, GST must be paid only at the time of supply, so it is an essential instrument. Due to increased GST compliance, GST revenue collected in March 2023 reached 1,60,122 crore. In this blog, we will explore the importance of a GST tax invoice and other instruments.What are Tax Invoices and Other Instruments in GST?
A GST-registered supplier must issue a GST-compliant tax invoice to the buyer at the time of supply or at the time of removal of goods from the supplier warehouse for delivery to the buyer. You must issue a tax invoice for the supply of taxable goods and services. As per the GST framework, the supplier must issue the invoice within 30 days of supply. The buyer can claim ITC to offset GST paid against purchases only with a GST invoice from the supplier. The different types of commercial instruments under GST are:- Tax invoice
- Advance payment receipt voucher

- Invoice in case of continuous supply of goods and services
- Invoice in case of service termination

What are the Components of Tax Invoices in GST?
The invoice format is standardised, as specific fields must be in the GST tax invoice. However, businesses can customise this invoice format and create an invoice template with their business name and logo as per their choice. Suppliers are responsible for issuing GST invoices if they are a registered vendor. Otherwise, the invoice will be considered invalid. As per the new rules of GST, the supplier must also generate an e-invoice using the e-invoicing portal and issue the e-invoice in place of the GST tax invoice. The following information must be mandatorily present in a GST invoice:- Name, address, and GSTIN of supplier
- Consecutive serial number of the invoice (it must contain alphabets, numerals, and special characters like hyphen, dash, or slash, and it must be unique for a financial year)
- Date of invoice issue
- Name, address, and GSTIN of the recipient (UIN for the unregistered recipient)
- Address of delivery location with state name and code
- HSN code of goods
- Description of supplied goods or services
- Quantity of supply
- Total value of goods or services or both
- Taxable value of goods or services or both
- GST rate (IGST, CGST, SGST)
- GST tax amount
- Place of supply with the name of the state
- Whether tax is payable on a reverse charge basis
- A signature or digital signature of the supplier or an authorised representative
Is an Invoice an Instrument?
In the legal context, an instrument is a legal document that transfers rights or obligations. For example, contracts, bonds, and promissory notes are instruments. Within the GST framework, an invoice is a commercial instrument. It is a legally required document issued for the specific purpose of a supply transaction. It is also a demand of payment for the supplier and crucial for the recipient to claim ITC. The GST tax invoice is the proof of supply document and a validation that the purchase transaction has occurred. It is also an essential tool of communication and necessary for tax compliance.What is the Difference Between a Tax Invoice and a Bill of Supply Under GST?
At the time of supply, the supplier must issue a GST-compliant invoice. However, a tax invoice is not always required in all cases. Knowing which type of commercial instrument to issue is essential for GST compliance. The differences are stated below:| Parameters | Tax Invoice | Bill of Supply |
| Use | Used by GST-registered businesses liable to pay GST for taxable goods | Used by companies registered under composition scheme or companies that supply exempted or NIL-rated or Non-GST goods or services |
| Purpose | Issued for supply of goods and services that incur GST | Issued for supply of goods and services where GST is not applicable (including composition scheme, supply of exempted or NIL-rated goods and services) |
| Content | Must include GSTIN, GST rate, HSN/SAC code, and GST amount | Does not include GST-related information |

What is the Difference Between a Tax Invoice and a Regular Invoice?
An invoice bill is a regular invoice that the supplier sends to the buyer with details, including goods or services purchased and the total amount due. A GST tax invoice is essential for suppliers supplying goods and services that incur GST tax. The regular invoice will not contain tax information even though the goods may be taxable. However, a supplier must always submit a GST tax invoice or bill of supply wherever applicable for GST compliance. A regular invoice is not a commercial instrument as per the GST framework. A GST invoice is necessary for B2B transactions, and a regular invoice can be used for B2C transactions, but it may not contain GSTIN details.What is the Difference Between a Tax Invoice and a Bill?
A bill is a generic term for a document that shows the total amount a customer must pay the vendor. An invoice is a specific commercial instrument that a supplier issues for supplying goods and services. For example, restaurants, shops, supermarkets, etc, issue bills to a customer who pays for the purchase before collecting the goods. The following table shows the differences:| Parameters | Invoice | Bill |
| Use | Used for credit transactions with due dates for payment | Used for cash transactions completed immediately |
