@Suzann1 Airbnb has just announced the same change here in Quebec. I will continue to send my lodging tax to the government, minus the Airbnb portion. I will keep a record, as I always have done, of where my revenues come from (private, VRBO, TripAdvisor and Airbnb). So far, the only one that will collect and remit funds directly after October 1st is Airbnb.
As to the statement that they will send all money in one lumpsum for each area...that is likely to change. I spoke to my local tourism advisor and was told that this is just the first step but the goverment will insist on separate accounting from each host according to the legal establishment number. If there is no establishment number it means that the taxes have come from an unregistered, illegal operation and the owners will be fined. So yet again Airbnb is misleading hosts in order that they can continue to collect money from the "illegal hosts".
