Mark, I just saw this, so sorry for the delay responding.
I'm not talking about the clients Airbnb account. I have one Airbnb account, as allowed. I have a different bank account for each client.
The bank accounts are in my name, with the client as a trust holder. If I die or become incapacitated, they will be able to access the account. I hate paying bank fees I don't have to, so I do not set up business accounts that would require tax #'s.
I receive payments in the bank holding accounts, and at the end of the month disburse the amounts for that months reservations to the clients, cleaner, and my commission. Occassionally I use those funds for maintenance and repairs, but until the guest arrives, those funds don't belong to me or the client. For all but one of the accounts, taxes are disbursed back to the clients and they file pay their own taxes. I have one account where we are set up with Avalara to file taxes for the client, and they pay the taxes out of the account after we report the amounts. So yes, the IRS and the state allow the client to manage payment of their taxes, just like they would for any other business.
I've never understood why Airbnb thinks they need to intervene for the property owner and pay taxes for them. Hawaii does not allow that.
