Hi @Jose7725
Taxes should have been added when you setup your listing? Airbnb collects and remits taxes for some juristictions automatically, but not for others. Airbnb forwards tax collection in one lump sum to the juristictions involved; they don't separate it by each listing. For this reason, Hosts should keep records of every reservation and the taxes collected in case the governmental agency requests you provide proof it was paid. Some Hosts use spreadsheets for that, others either keep an electronic copy of each reservation, or print it out for each reservation. Hopefully, you have been keeping track?

For those locations that Airbnb does not collect and remit taxes, the Host is responsible for collecting it from guests for each reservation and then paying the taxes when due (there is a manual way to add a tax on the platform). Hopefully Airbnb has been collecting the taxes all along for you? If not, that might be an issue as you would still owe the tax even if you didn't collect it from guests. You can simply look at a reservation and see if "Occupancy Taxes" are listed under "Guest Paid."
You can also go to your Listing Page/Policies & Rules. Scroll to the bottom and you will see Taxes. Click edit. If Airbnb collects taxes, it will be listed there.
