Taxes depend on your actual legal address? Airbnb doesn't always collect taxes for every jurisdiction. If there is a tax required that Airbnb does not collect, Hosts must add a custom tax to their listing in order for it to be added to every reservation. The Host is then responsible for remitting the custom tax to the appropriate governmental agency; not Airbnb. You would have to contact Airbnb regarding your situation. Unfortunately, if a tax is required, but not collected on your previous bookings, you will still owe the tax. You should have seen "Occupancy Taxes" listed on every reservation. Airbnb groups all taxes (sales tax/lodging tax) under the heading "Occupancy Taxes" in a reservation. Most Hosts keep a spreadsheet and breakdown the sales tax and lodging tax in case it is needed at tax time.

If you are in unincorporated Eagle County (not in the town of Gypsum), then looks like Eagle County’s 2% lodging tax would apply to every booking (in addition to sales taxes that apply – State/local).
