@Michelle193 What an odd request. But if you really want to do it, it's not that diffcult, but will have some implications for both you and your guests.
Let's say your standard rate is $100/night, and that you don't charge a cleaning fee. AirBnB is going to charge you a 3% fee on that $100. So, you can increase your nightly rate to $103 to get back that 3% (=$3) fee. But now you've upped your 3% fee from $3 to $3.09. And you've upped your guest's typical 12% fee from $12 to $12.36. I'm ignoring AirBnB's rounding policy here, but while it wouldn't kick in for a one-night booking, it would (for the guest) for a 2-night booking, and would for you for longer bookings.
The whole calculation gets trickier if you have a cleaning charge, of course.
I always find it strange when hosts want AirBnB to provide ways to "add on" a fee for the host's local taxes, and I find this idea of yours even stranger. (Not saying that you're strange or anything, or even wrong.) I simply think: price your listing at whatever rate you a) need it to be and b) can get for it. While, at the same time, taking into consideration whatever local taxes and licensing fees you pay and whatever commission you have to pay to AirBnB. Meaning that if you feel you need to get $100 night to cover your costs and make the profit you want to make, then charge $103 (or $104 or $105) per night as long as you can get guests willing to pay that amount. The way that we run our listing is we set rates (variable each and every day, and revisited every few days) to the maximum amount we can get guests to accept (and go away happy). If we're not getting booked at a satisfactory level, we reduce our rates slightly. Seems to work. We book up 80-90% 3 months in advance, 95% two months in advance. If we tried adding add'l fees for local taxes and AirBnB's fee, we'd book up less and later.
I certainly don't know how federal income taxes work in Australia, but in the US, all of those contributors to earnings and costs can be worked out when filing taxes.
