The hourly, daily and monthly prices you list for your space are always tax inclusive. Guests do not pay any additional tax on price you list when they pay for the booking. Depending on what province or state you're in as a host, you may need to collect taxes for each booking.
We encourage you to incorporate a tax percentage in your rates. For example, instead of charging $400/day, charge $450/day.
It is important that you inform guests if you are adding tax onto the final offer. Our site is very transparent, and not including these costs upfront could deter some guests.
