Under Rule 46 of the Central Goods and Services Tax (CGST) Rules 2017, every registered business in India issuing a B2B or B2C bill must include specific mandatory invoice fields to ensure full legal tax compliance and enable buyers to claim Input Tax Credit (ITC).
Mandatory GST Invoice Fields Required by Law:
- Supplier Details: Business name, registered address, state code, and 15-digit GSTIN (Goods and Services Tax Identification Number).
- Consecutive Invoice Serial Number: A unique alphanumeric serial number containing only alphabets, numerals, or special characters (hyphens or slashes), unique for each financial year.
- Date of Issue: Exact date when the invoice was generated and delivered to the recipient.
- Recipient Details: For B2B sales exceeding Rs. 50,000, recipient name, address, state code, and GSTIN are compulsory.
- HSN / SAC Codes: 4-digit HSN code for businesses with turnover up to Rs. 5 Crore; 6-digit HSN code for businesses with turnover exceeding Rs. 5 Crore.
- Tax Split Breakdown: Distinct itemization of Central Tax (CGST), State Tax (SGST) for intra-state sales, or Integrated Tax (IGST) for inter-state sales.
