  • You can claim input tax credit (ITC) on purchases
  • Most common setting for registered suppliers

  • No tax will be charged on purchases
  • Common for certain types of goods or services

Non-Taxable

  • Supplier is not registered for tax

  • This determines whether CGST+SGST or IGST applies

Common Tax Scenarios
