The assessor has no control over the tax rate. The County Clerk’s office is responsible for calculating real estate tax rates for all taxing districts within Winnebago County. There more than 100 taxing districts, which receive property tax revenue. Additionally, local citizens can influence spending by voicing their views to the proper officials. The tax rate is dependent upon 1) school and local governmental levies [the amount of money a taxing body certifies to be raised from the property tax], 2) the statutory limits and 3) voter's response to referenda issues.
