Taxable event and point of time for payment of tax were two different aspects under indirect tax law in preGST era. In this chapter we shall only be dealing with the subject of levy under GST regime i.e. taxable event for the purpose of levy of GST.
In any fiscal statute, the most important section is the Charging Section of such statute. Under GST Regime subject of levy is dealt in—
— Section 9 of the Central Goods and Services Tax Act [CGST Act]/State Goods and Services Tax Act [SGST]
and
— Section 5 of the Integrated Goods and Services Tax Act, 2017 [IGST Act].
Thus, section 9 of CGST Act/SGST Act and Section 5 of IGST Act are the Charging Sections for the purposes of levy of GST.
CGST and SGST shall be levied on all intra-state supplies of goods and/or services and IGST shall be levied on all inter-state supplies of goods and/or services respectively.
