Airbnb aims to secure 700 tax agreements in cities that generate more than 90% of its revenue by the end of next year, as it tackles regulatory battles in key markets such as New York and San Francisco. The accommodation company has 200 existing tax deals, which allow it to collect and remit hotel taxes to local governments, and is looking to boost the number by another 500, Airbnb (Private:AIRB) CEO Brian Chesky told FT.
