Trustee Bill Hullander said Wednesday that Airbnb has agreed to directly remit hotel/motel tax for its 600 hosts in Hamilton County to his office.
Mr. Hullander said prior to the agreement that his office had difficulty locating those renting out rooms or homes and had just 90 on the books.
The agreement is slated to boost the current hotel/motel income from $85,000 to $560,000.
He said Airbnb will not divulge the names and locations of the individual hosts, but will collect from all of them.
Airbnb in 2017 announced an agreement with the Tennessee Department of Revenue to collect state and local sales taxes on all bookings throughout the state.
It later set up agreements with Memphis and Knoxville to collect their occupancy taxes.
The payments are to start next month.
Chattanooga is airbnb's third largest market in Tennessee - behind only Nashville and Memphis. About 62,000 airbnb guests experienced Chattanooga in 2017.
The city of Chattanooga took steps last year that allowed short-term rentals in much of the city.
