Comprehensive GST Invoicing Guide for India

Under the Indian Goods and Services Tax framework, registered suppliers must issue valid GST-compliant invoices containing specific statutory details to enable purchasers to claim Input Tax Credit (ITC).

1. Mandatory Details on a GST Tax Invoice

  • Supplier Identity: Legal business name, registered address, and 15-digit GSTIN.
  • Consecutive Serial Number: Unique numeric or alphanumeric invoice numbering (not exceeding 16 characters).
  • Date of Issue: Transaction date.
  • Recipient Details: Customer name, billing address, and GSTIN (for B2B transactions).
  • Place of Supply: State name and 2-digit GST state code.
  • HSN / SAC Codes: Harmonized System of Nomenclature code for goods and Services Accounting Code for services.
  • Tax Breakup: Clear itemized bifurcation of CGST & SGST (for intra-state) or IGST (for inter-state).

2. Tax Invoice vs Bill of Supply

• A Tax Invoice is issued by regular GST-registered businesses when charging GST on taxable goods and services.
• A Bill of Supply is issued when selling exempted goods, or when the taxpayer is registered under the GST Composition Scheme (where tax cannot be collected from the customer).

3. Frequently Asked Questions (FAQ)
