GST Invoice Format: What Every Business Owner Must Know

GST invoices are essential for record-keeping and transparency. GST invoices are more than just a record-keeping document for business owners. They provide the foundation of the GST invoicing requirements, facilitating the smooth transfer of input tax credits from producers to final customers. Every time a B2B or B2C transaction takes place, a GST invoice has to be sent, as required by the GST authorities. Various tools can be used to design it based on your needs. The instructions for creating and downloading GST invoice formats in Word, Excel, and PDF are provided in this article. The primary goals of this guide are to clarify the fundamentals of GST invoicing, such as the need for compliance with GST billing laws, the format of invoices, and the role that technology plays in expediting the procedure.

GST Bill and its Key Components

A registered supplier will present their consumers with a GST invoice that includes information about the goods or services they have provided, the total amount charged, and the applicable GST. The GST invoice is an essential document for claiming input tax credit (ITC) and acts as evidence of the provision of goods or services. Every sale made by a GST-registered firm requires you to send out a GST invoice. It lists all of the products and services you have given the customer, together with the price they have to pay. The GST law also requires a correct GST invoice. Here are the key components of a GST bill:

  • Name, address, and GSTIN of the supplier

  • Consecutive serial number for a financial year (unique)

  • Issuing date

  • Name, address, and GSTIN/UIN (if registered) of the recipient

  • Address and state code of the recipient if unregistered (for a value exceeding ₹50,000)

  • Description of goods or services

  • Quantity for goods/Unique Quantity Code

  • HSN code for goods sold/Accounting Code for services sold

  • The total value of supply

  • Taxable value of supply 

  • Tax rates (central, state, union territory, integrated, or cess)

  • Tax amounts 

  • Place of supply with the name of the state for inter-state trade

  • Delivery address if not the same as the site of supply

  • Indication of applicability of reverse charge

  • Signature or digital signature of the supplier

For the invoice to be legitimate and to make the Input Tax Credit (ITC) claim process run smoothly, it must follow the official GST format. ITC refusal, fines, and litigation can result from noncompliance.

Business HSN code reporting is as follows as of April 1, 2021: 

  • All invoices with a turnover of more than Rs. 5 crore must have a 6-digit HSN code. 

  • All B2B invoices with a turnover of less than or equal to Rs. 5 crore need a 4-digit HSN code. 

  • For B2C bills, this reporting is not required, though. 

Previously, the reporting for businesses was as follows until March 31, 2021. 

  • Less than 1.5 crores in revenue: HSN code is not necessary to be stated.

  • With a turnover of 1.5 to 5 crores, a 2-digit HSN code may be used. 

  • Use of a 4-digit HSN code is required for turnover over 5 crores. 

GST Invoice Format for B2B Businesses

The business-to-business (B2B) model refers to the exchange of goods and services. In order to do this legally, the B2B invoice format in GST offers the foundation upon which all the necessary information is arranged, such as the recipient's and seller's HSN codes and GSTINs. GST Invoice

Format for B2C Businesses

Sales of products or services to final consumers take place directly under the B2C model. The structure for listing all sales information, such as price, quantity, total amount, and tax, is provided by the B2C invoice format in GST; however, the recipient's GSTIN is not included. 

GST Invoice Format for Export of Goods and Services

An export invoice's details are the same as those of a tax invoice. However, if the destination is not registered and the value of the supply exceeds Rs. 5,000, the name of the country must be provided on the export invoice in place of the state name and code. Furthermore, the following guidelines must be followed:

  • According to the GST Rules, the invoice must have an endorsement if goods or services are being exported. 

  • A shipping bill is an additional crucial document that needs to be sent with the export invoices. Exporters are entitled to a return of their accumulated Input Tax Credit (ITC) for the tax period under the terms of the GST Law. When processing refund requests, shipping expenses are given first priority by the GST authorities. Therefore, in order to apply for a refund, one must be careful to ensure that export invoices are always accompanied by the appropriate shipping bill.
