Understanding HSN/SAC Codes and GST Calculations

What is an HSN or SAC Code?

Under the Indian Goods and Services Tax (GST) framework, HSN (Harmonized System of Nomenclature) codes are used to categorize physical goods, while SAC (Services Accounting Code) codes classify services. Including these codes on your tax invoice ensures accurate tax classification and compliance with Central Board of Indirect Taxes and Customs (CBIC) requirements.

Intra-State vs. Inter-State Tax Calculations

  • Intra-State Supply (Same State): When supplier and buyer are in the same state, tax is split equally between Central GST (CGST) and State GST (SGST). For example, an 18% rate becomes 9% CGST + 9% SGST.
  • Inter-State Supply (Different States): When supplying to a client in a different state, Integrated GST (IGST) is applied at the full tax rate (e.g., 18% IGST).
