@Alina817 I have had 2 properties for 5 years, and this is just the way Airbnb does it. All pass-thru taxes are sent to the primary account.
It’s never been a problem, except, as you say, it’s less convenient to use the non-primary account to bookkeep all of your revenue, expenses and passthru taxes for the associated property. To solve that, I have a spreadsheet in which everything is broken out. I have guests in the rows, and categories, including all the different taxes, fees, number of nights, payouts, etc. in the columns, and I’ve created formulas for them. All I have to do for each guest is enter the guest name and nightly rate, and the spreadsheet does the rest.
You don’t have to worry about the IRS having the wrong figures, because Airbnb separates out the guest-paid accommodations taxes from the rest of the incoming revenue and gives them a different title/designation.
There is also a PDF table you can generate and download from Airbnb that shows, among other things, the taxes broken out for each guest. I personally don’t reference that very often, but you may find it helpful.
