Realized on my Synergy bill, GST is calculated on my usage prior to deductions/credit on Buyback (which doesn't have GST).
Probably somewhere in T&Cs, and being in WA it's our only choice.
Bill at the moment = Usage + GST, less buyback (NO GST).
However bills would be cheaper if they had calculated such as (Usage - credits) then applied GST on the balance.
I can understand both perspective of the accounting behind it, but wondering what other's thoughts are.
First instance: You bought x units of power - here's the cost. Know lets deduct your account credit.
Second Instance: You bought x units of power, but exported y units of power - lets calculate the difference then apply GST on the final owing.
You're not registered as a business to be able to charge GST on the product you're selling in this transaction, are you?
