Tax Invoicing Regulations for Indian E-commerce

Understanding GST compliance constraints for marketplace transactions.

Mandatory GST Invoice Fields

A valid tax invoice in India must contain specific fields: the GSTIN of the seller, sequential invoice serial numbering unique for the financial year, description of goods, HSN code, state of supply, and details of taxes split by type (CGST, SGST, or IGST).

CGST/SGST vs IGST Rules

Taxes depend on the warehouse origin and customer destination. If shipping inside the same state (Intra-state), you must split the GST rate into equal parts of CGST (Central GST) and SGST (State GST). For shipping to another state (Inter-state), apply the full rate as IGST (Integrated GST).

Invoice Numbering SOPs

To ensure GST filings are clean, use consecutive numbering codes (e.g., `INV/2026/001`, `INV/2026/002`). This format makes reconciling ledger books easier and reduces audit triggers. Avoid duplicate numbers across billing lines.
