You don't have to guess.

Just click a couple of links, the first link to my journal entry on the state tax report and then the link to the report.
Property taxes in Florida do not seem as huge as sales taxes. In Florida, the bottom 20% pays an average total tax rate of 13.5%. 9.4% from sales taxes and 4.1% from property taxes. The middle quintile pays 9.0%, 6.2% from sales taxes and 3.0% from property taxes. The top 1% pays 2.1%.
In Kansas, the bottom quintile pays 9.2% - 6.3% from sales taxes (which Brownback wants to increase), 3.5% from property taxes (not much different from Florida) and minus .6% from income taxes (which Brownback wants to eliminate). The middle quintile pays 9.0% (the same as Florida) - 4.2% from sales tax, 2.4% from property tax and 2.4 from income taxes. In Kansas, the top 1% pays 5.9% thanks to 3.5% from income taxes (which Brownback wants to eliminate).
So property taxes are a little higher in Florida, but not hugely so.
