Scope and assumptions
This calculator applies the rate you enter. It does not determine registration liability, exemption, reverse charge, input tax credit or compensation cess. The example rate is not a classification recommendation. The inclusive price method follows Rule 35; the split assumes equal central and state or territory components.
