Types of GST Invoices
A GST invoice is a legally required document issued by a supplier to the recipient for goods or services provided. The format and type of invoice vary depending on the nature of the transaction, tax liability, and the category of taxpayer. Using GST Invoice Format in Excel, businesses can generate different types of GST invoices efficiently while ensuring compliance with tax regulations.
1. Tax Invoice
A Tax Invoice is the most common type of invoice used under GST. It is issued when a registered business sells taxable goods or services to another registered business (B2B) or an unregistered buyer (B2C). This invoice allows the recipient to claim an Input Tax Credit (ITC) on the GST paid.
Mandatory Details in a Tax Invoice
✔ Supplier’s name, address, and GSTIN
✔ Invoice number and date of issue
✔ Recipient’s name, address, and GSTIN (if registered)
✔ HSN/SAC code for goods or services
✔ Description, quantity, and unit price of goods/services
✔ Applicable CGST, SGST, and IGST rates
✔ Total invoice amount including GST
✔ Signature of the supplier
2. Bill of Supply
A Bill of Supply is issued by composition scheme taxpayers and businesses dealing in exempt goods/services. Since composition scheme taxpayers cannot collect tax separately, this invoice does not include GST.
Who Should Issue a Bill of Supply?
✔ Composition scheme dealers who pay a fixed tax rate without ITC benefits
✔ Suppliers of exempt goods and services under GST
Key Features of a Bill of Supply
✔ No GST is mentioned or charged
✔ Contains the phrase “Composition Taxable Person, Not Eligible to Collect Tax on Supplies”
✔ Details of the supplier and recipient
3. Export Invoice
An Export Invoice is used when goods or services are sold outside India. As exports are treated as zero-rated supplies, exporters must issue an invoice specifying whether the supply is made with or without payment of IGST.
Essential Details in an Export Invoice
✔ Invoice number and date
✔ Supplier’s name, address, and GSTIN
✔ Buyer’s name, address, and country
✔ Shipping details (port code, bill of lading, etc.)
✔ Declaration stating “Supply meant for export under bond or LUT without payment of IGST”
4. Reverse Charge Invoice
A Reverse Charge Invoice is issued when the recipient, instead of the supplier, is liable to pay GST under the Reverse Charge Mechanism (RCM). This applies to specific goods, services, and transactions notified by the government.
When Is a Reverse Charge Invoice Required?
✔ Services from unregistered to registered businesses
✔ Specified categories such as legal services, import of services, and transportation services
Key Details in a Reverse Charge Invoice
✔ Clearly states that the recipient is liable to pay GST
✔ Details of supplier and recipient
✔ HSN/SAC codes and transaction details
5. Debit Note & Credit Note
Debit Note
A Debit Note is issued when the original invoice value is lower than the actual value of goods/services supplied. This is done to recover the difference amount from the buyer.
Credit Note
A Credit Note is issued when an excess amount was charged in the original invoice, or goods are returned by the buyer. The seller refunds the excess amount to the recipient.
Components of a GST Invoice
A GST invoice is a crucial document that a supplier must issue when supplying taxable goods or services under the Goods and Services Tax (GST) Act. It serves as proof of a transaction and is essential for both compliance and claiming Input Tax Credit (ITC).
A well-structured GST Invoice Format in Excel must include specific details to ensure compliance with tax regulations. Below are the key components of a GST invoice.
