I have a family trust with a corporate trustee (Trustee Pty Ltd). I want to run a business and I want to use Trustee Pty Ltd as the trading vehicle (i.e. it will be trading in its own right, not in its capacity as trustee). As part of this, I would need to get Trustee Pty Ltd its own ABN and register for GST. What are some consequences I may not have considered from these actions? If I register Trustee Pty Ltd for GST, would trust income suddenly be subject to GST?
