we, the consumers, are at the bottom of the pile, ie we pay the most in terms of GST as we are the target of this consumption tax
the impact of 1% increase does not equate to 1% for us
take the example from the vid of kopi. If we are buying from the coffee stall at the market, it is likely that the coffee is not GST registered hence, although he cannot charge GST, he has to absorb the GST that are charged to him as he is dealing mostly like with GST registered SMEs
So, he will be paying 1% extra for the water and electricity, the coffee powder, the sugar, the rental, the milo powder and can drinks, almost everything went up 1% .
ALL these goes into the $0.80 to $1.50 kopi
