@Norma6 for those of us who are not lucky enough to have Airbnb collect Occupancy taxes on our behalf, there are only two options as described in this help article:

I just include it in my nightly price and while that has its downsides, it make things much easier for me and my guests. I pay the taxes monthly on the gross reservation price, before the 3% Airbnb fee is deducted.
Not very satisfactory, I know, but I'm hoping that Airbnb is developing a way to add taxes like they do the cleaning fee.
