Is this the right county?
The surtax follows the transaction, not your business address. You charge Monroe County's rate when the sale is sourced here — for tangible personal property that means delivery into Monroe County, for services where the service is performed or delivered, and for motor vehicles and mobile homes the purchaser's registered address rather than where the vehicle was handed over. A seller in Key West shipping to another county charges that county's rate instead.
The full sourcing rules cover transient rentals, aircraft and boats.
