Thank you for the reply. I should have mentioned that I'd much rather enter county data, instead of zip code data, but that doesn't seem to be an option. In Florida, many counties charge a surtax, whereas, Florida's base sales tax is 6%. Is it legal to keep it simple, charge 6% statewide and balance it out later, and just eat the difference for the counties with a surtax? (fyi, Florida is a destination based / buyer based state).
