How do I set my entity type — LLC, S-corp, sole proprietor?
ComputerOpen Settings, then Business profile, Entity Type and Save Changes.
PhoneOpen Settings, then Business profile and Entity type.
Entity type changes the tax math, not just a label, so the app warns you before it takes the change. If you elected S-corp mid-year, set it and then check the Taxes page — the estimate rebuilds around a reasonable-wage split.
