What percent of taxes is taken out of paycheck for Florida?

Florida does not have a state income tax. However federal taxes still applies. As such their would be 7.65 withheld for Social Security and Medicare. The amount of federal with holding would depend on what the employee claims on their W-4; i.e. "married and three allowances" would have less withholding than "single and one". Remember that Florida has a great number of retirees and does have an annual tax on investment holdings. You may want to consult a publication called All States Tax Guide.
