AirBnb does not understand about world wide taxation systems. On a territorial taxation country where I live (Costa Rica) you pay VAT tax ONLY if goods are consume locally within its territory. If booking is out of Costa Rica borders (out of its territories) than you DO NOT pay taxes.
For a Global taxation system as the USA, you pay taxes no matter where you consume services.
Airbnb is ilegally charging taxes incorrectly or does not understand how taxation is done worldwide with different taxation system.
It is obvious AirBnb is NOT a wordwide company as many US companies that does not understand geography or taxes. Been a American San Francisco-based company this makes. sense.
Hard to believe it is on the stock market, who will invest a a company that does not know its own business...
