Tax guide notes

  • - GST rate is not embedded in HSN/SAC master data. Confirm the latest rate from GST rate notifications and official CBIC schedules.
  • - Invoice accuracy matters: use the code that best matches the principal supply description to reduce notices and mismatch risk.
  • - If supplies include both goods and services, document the dominant nature of supply before selecting HSN/SAC.

Compliance checklist

  • - Keep product/service description on invoice aligned with the selected HSN/SAC code.
  • - Review code selection whenever scope of work or product mix changes.
  • - Cross-check applicable GST rate, exemptions, and reverse-charge conditions before filing returns.
