I doubt that a large number of hosts operate an Airbnb inside a trust. Trusts are difficult to begin with (FICA, high taxes, etc.), and the fact that it's not a mainstream way to do business with Airbnb is probably making it even harder for you to tick all of Airbnb's boxes. I'm not sure how your struggles began, but if there's any way that this may be a recurring (annual?) problem between you and Airbnb, it may be good to find an easier solution. Can't you just host in your own name on Airbnb (as a straightforward natural person) and set up a contract (between yourself and the trust) that you will transfer all of the Airbnb income to the trust?
@Nicola3819. Hi Dave, sorry I'm not a SA host but cant you supply the Beneficary Schedule part of your trust deed and any relevant definition sections to show who the actual beneficiaries are? I'd be suprised if its your accountants because that would hardly be "neutral".
