Similar to #1256530: Ubercart charging twice for sales tax , but this is a D7 site.
Orders with a Florida delivery address have sales tax added twice, there are no duplicates in the rules_config or uc_taxes tables in the database.
I have tax conditions in 2 places, admin/store/settings/taxes/manage/uc_taxes_3 and admin/config/workflow/rules/components/manage/16. I'm assuming that's normal because that's how the other state sales taxes are set up and those aren't being added twice.

OldAccount commentedI just noticed something else -- the way the tax was calculated is not correct.
It should have been this:
Subtotal $50.00 + 3.99 shipping = $53.99, 6% tax = $3.24
Instead it did this:
Item total $25 + 3.99 shipping = 28.99, 6% tax = 1.74
Item total $25 + 3.99 shipping = 28.99, 6% tax = 1.74

tr commentedYour screen shot clearly shows that you have two separate, independent taxes being applied. They both happen to be named "Florida Sales Tax". I suspect, even though you haven't said, that you have multiple tax rates set up and you are using Rules to select which one to apply. This requires you to define your Rules so that one and only one of the multiple rates will be selected for any order. Your Rules are apparently selecting two rates. Without specifics of how you have your tax rates configured, what your Rules are doing and what variables they're testing, it's impossible to guess just where you went wrong. As this forum is not intended for support issues, I suggest you post on ubercart.org and provide more detailed information if you need someone to help you debug your tax configuration.
