It's the surprise no one wants in their property tax bill - taxes are going up.

Property taxes help pay for things like public schools and your local police and fire departments.
PolitiFact Wisconsin says how much you pay depends on the fair market value of your home or business.

PolitiFact Wisconsin says property taxes in Wisconsin are among the top five highest in the country.
But as for Wisconsin property taxes going down, "There's a few problems with this statement though," said Borowski. "It's not all due to budget cuts or changes in tax policy. There are other factors at work such as property values declining or business or commercial taxes rising whereas residential taxes are falling."
