Time of supply

Time of supply will be 15/8/2019 , Date of issue of Invoice as per section 12 of the CGST act 2017
please confirm with others also .

Time of supply of goods is earliest of:
1. Date of issue of invoice
2. Last date on which invoice should have been issued.

So, in your case Time of Supply is 15th August, 2018 (i.e date of invoice)

(In Query date of invoice is written as 15.08.2019,but I think it should be 15.08.2018 and answered accordingly)

Yes , by mistake I have also written date 15/8/2019 , It should be 15/8/2018 , please clarify .
