I am another non-accountant, but my understanding is that I am part of the OC (it is not a third party entity) and jointly liable (to the extent of my UEs) for its debts. I simply contribute to a pool of money to pay for my share of the expenses (which will most probably have a GST component – I don’t see why I would have to pay GST twice on the same bill).
I have a credit card which pays my bills, and I reimburse the CC company at regular intervals and I do not get charged GST for that.
Could Missy please explain where my logic is failing?
