Are you registered under a business name or personally? Did you take any further steps like forming an LLC?
One of our airbnb’s is at our farm so we do operate under that business name. We also added our granny flat at home to be part of this business as it keeps it all together.
I’m also not sure which is better to do, it kind of depends on how well the airbnb property does and whether it makes sense to get taxed as a company or an individual.
