@Joanne686 @Kimo19 The GET and TAT gross revenue is based on what the guest pays. Here is a full description. A definition of gross revenue and fees to include are in #4.

Please also keep in mind that the GET gross revenue will be a little more, as you have to include the GET tax itself in the revenue and pay tax on it (I know, mind-boggling). That’s why you should collect 4.167% tax from the guest for GET, instead of 4%.
Also, keep in mind that none of your expenses should be deducted from the revenue. So, even if you have to pay a housekeeper, you still include the housekeeper fee the guest paid in the revenue. GET and TAT taxes are simply the taxes that the GUEST is paying to rent the accommodation.
Also keep in mind that host/guest Airbnb management fees are not included in gross revenue, since you as the host never receive those fees.
