What Makes an Invoice Legally Compliant?

Under Rule 46 of the CGST Rules, a valid tax invoice must contain 16 mandatory fields. Missing any of these details can cause your client to lose their Input Tax Credit (ITC) claim:

  1. Supplier Name, Address, and GSTIN.
  2. Consecutive Invoice Serial Number (unique for the financial year).
  3. Date of Issue.
  4. Recipient Name, Address, and GSTIN (for registered buyers).
  5. HSN Code of goods or SAC Code for services.
  6. Description of goods/services, quantity, unit rate, and total taxable value.
  7. Separate rate and amount of CGST, SGST, or IGST.
  8. Place of Supply with State Name and Code.
  9. Signature or Digital Authenticator.
