To assess means to determine the value of something. The Township Assessor is an elected official who determines the value of property for tax purposes. The Assessor does not estimate or compute the Real Estate Taxes, does not send out Tax Bills, and does not collect Property Taxes. The Assessor is responsible for the fair and equitable appraisal of every parcel of property in his or her jurisdiction.
The Township Assessor keeps Property Record Cards which contain all the pertinent information about each parcel. The information includes the following: a brief legal description, land size, dimensions of all buildings, building type, and quality of materials used in construction of the structure. Most of this information is gathered when the property improvement is first built, and then updated afterward through periodic field inspections. Property Record Cards are available for inspection through our website.
The Township Assessor also receives Real Estate Transfer documents for properties that have sold in the Township. This sales information, along with other facts and figures about housing conditions, goes into the valuation process. The Assessor estimates how much a property would sell for on the open market.
Market Value, as used in the appraisal of real estate, is defined by the Appraisal Institute as:
The most probable price, as of a specified date, in cash or in terms equivalent to cash, or in other precisely revealed terms, for which the specified property rights should sell after reasonable exposure in a competitive market under all conditions requisite to a fair sale, with the buyer and seller each acting prudently, knowledgeably, for self interest, and assuming that neither is under duress.
The basis for all assessments and reassessments is Market Value (occasionally the terms "full value" or "fair cash value" are used. According to Illinois State law, all property in Illinois (except Cook County) should be assessed at 33.33%, or one-third of Market Value. This is known as the Level of Assessment. For example, if a home could be sold for $330,000, the Assessed Valuation would be approximately $110,000 ($330,000 x .3333). Once the Market Value of a property is determined, the Township Assessor places the value of the property at the required percentage which results in the Assessed Valuation.

Your annual property taxes are made up of levies from the individual taxing bodies that service your area. Each taxing body determines how much money is needed to operate for the upcoming year, and how much needs to be raised through property taxes. The amount to be raised is the levy. The levy is sent to the County Clerk where the tax rate is calculated by dividing the total amount of assessed value in the jurisdiction by the levy. The following charts display the breakdown for a typical home in Aurora within School District 204, and one for a home in Naperville within School District 203 boundaries.
