State statute provides several thousand local governmental districts the power to assess real estate taxes. Nonetheless taxpayers most often pay just one consolidated tax levy from the county. Every entity then gets the assessment amount it levied. Overall, there are three phases to real estate taxation: creating tax levies, evaluating property worth, and then collecting the tax.

Counties and Island Lake in addition to thousands of special purpose districts hold taxing authority under Illinois law. They are legal governmental districts run by officials either appointed or elected. Such units, e.g. public schools and hospitals, serve a particular area, i.e. a county, township, school district, et al.

The state’s statutory rules and regulations must be adhered to in the city’s conduct of taxation. Taxation of properties must: [1] be equal and uniform, [2] be based on current market worth, [3] have a single appraised value, and [4] be considered taxable in the absence of being specially exempted. Taxpayer’s rights to reasonable notification of rate raises are also required.

Across the United States, three ways for determining market worth prevail (with differing versions). A Sales Comparison is founded on comparing average sale prices of equivalent real estate in the community.

A Cost Approach also is principally a commercial property worth computation method that adds the land worth to the expense of replacing the building.

Typically at least once every three years a county assessor re-evaluates and decides whether to recalibrate property’s estimated market value. A reappraised market value is then multiplied times a total levy from all taxing entities together to calculate tax assessments. Those entities include Island Lake, the county, districts and special purpose units that produce that total tax rate.
