1. Overview


It is necessary to know the date on which the tax liability arises, i.e. the date on which the charging event occurred, in order to calculate and discharge tax liability. It is referred to as Time of Supply (TOS) in the GST Act. The GST Act includes provisions for determining the time of supply of goods and the time of supply of services.


Once the time of supply (TOS) is determined, the rate of GST and the amount of GST payable at that time are calculated, and such liability is to be discharged by making GST payment within the time specified.


2. TOS of Goods


The obligation to pay tax on goods arises at the time of supply in the following circumstances:

i. Supply of goods, where supplier is liable to pay tax under normal situation i.e. forward charge (Normal Charging Mechanism a.k.a NCM)


a) Date of issue of invoice by the supplier. If the invoice is not issued, then the last date on which the supplier was legally bound to issue the invoice# w.r.t the supply, or

b) Date on which the supplier receives the payment## (Not Relevant for advances received for supply of goods).

whichever is earlier

# Last date for issuance of invoice shall be determined in the following manner-
