renonewbie1 0 Report post Posted June 30, 2017 Hi everyone, Need some advice! anyone has experience dealing with GST registered ID firms that can waive off GST? Am about to sign contract with an ID firm, and was asking the ID about the GST since they are a gst registered company. She then said that if we pay in cash, she will be able to minus off gst. she will generate a separate quote for us with their non-gst registered sister company. but i am concerned about the company's accountability since the contract is signed with the sister company on paper.. is this a common practice? would appreciate any help or feedback!
