UHT filing requirement for a de facto trust and pricing

Two questions:
1- Do you mind sharing how much you all are charging for UHT filing. And do you just multiply that by the number of properties if a client has multiple properties? Do you charge the same for individuals and corporations? Or do you just bill hourly because it might take some time getting all the information from the clients?

2- If two people are on title of a rental property, but only one reports the income, does the party that is not reporting the income need to file because they are effectively holding their share in trust for the other party? In this case, there is no bare trust agreement or any formal trust setup.
