Michael - have you figured this out? I'm having the same issue. Airbnb collects Texas state tax, but not the City of Austin Hotel Occupancy Tax. I found this on the city's website.
Is AirBnB paying on behalf of the property owner City of Austin Hotel Occupancy Tax?
AirBnB is NOT collecting the City of Austin Hotel Occupancy Tax of 9% from the property owner and AirBnB is NOT remitting the 9% City of Austin Hotel Occupancy Tax to the City of Austin . Currently AirBnB is collecting and remitting the 6% State Hotel Occupancy Tax to the State of Texas. The owner of the property is responsible for collecting and remitting the 9% City of Austin Hotel Occupancy Tax on a quarterly basis.
I found this on the Airbnb site, but I don't even see a "local taxes and laws" section on my listings page.
If we collect and remit taxes for your listing (default taxes)
If we already collect some taxes for you, there are two ways you can add taxes to your listing, depending on the jurisdiction your listing is in.
The first way lets you choose between default and custom tax collection. If you choose custom tax collection under this option, we'll only collect the taxes you add.
Go to your Listings page and click the listing that you want to edit
Select Local taxes and laws
Choose Custom tax collection
Click Add a tax
Select the Tax type from the drop-down menu
Select the Type of charge and then add the amount being collected in the box under Amount
Add your Business tax ID and Accommodations tax registration number (read additional info about tax IDs below)
Choose whether your region provides an exemption for long-term stays (if you choose Yes, you’ll be given the option to provide additional details)
Agree to the terms and click Save
If you later remove all custom taxes, you’ll automatically switch back to default tax collection.
