Property Tax

Every Oak Park property pays a small share of Oak Park’s $199 million tax burden.

A property’s share of the burden is determined by comparing its assessed value to Oak Park’s overall assessed value.

Thus, a property that comprises 1% of the total assessed value of Oak Park pays 1% of Oak Park’s total tax burden.

Spending increases will raise the community’s overall tax burden, and changes in your property’s share of the burden will determine whether it pays a larger or smaller portion of the increased community-wide tax burden.

Frequently Asked Questions

In 2017, the state legislature approved a new program that provides state aid to school districts with very high property tax rates.  This year, twenty-eight Illinois school districts, including Oak Park and River Forest High School, qualified for financial aid under the new program.  The program provided the high school an extra $3.8 million in state aid this year, but in exchange, the school had to reduce its property tax levy.  This year’s levy is $4.5 million less than the levy from last year.

Ordinarily, the high school and most other taxing districts have the right to increase their tax levies by an amount equaling the annual rate of inflation.  If the school had not received the extra money from the state, it would have sought an inflation-level tax increase this year, and the result would have been a 4.4% tax increase for most property owners in Oak Park.  Thanks to the extra state money, however, the typical tax increase in Oak Park is just 2.1%. 

Local taxpayers should enjoy the tax relief provided by the new state program, but understand that it may not last.  The high school should remain eligible for this increased aid from the state for a number of years, but the additional money is not guaranteed, as the state could fail to fund the program or alter the eligibility rules.  In addition, program rules require the school district to reduce its tax levies in the initial year of the program, but apparently, do not require tax reductions in subsequent years.  Thus the duration of this year’s tax relief depends on decisions of the state legislature and the high school board. 

The reduction in the high school’s levy was offset by tax increases from local governments that did not receive new state aid targeted at reducing property taxes.  These increases, however, were generally moderate.  For example, the Township, the Park District, and Oak Park’s Village government each posted tax increases of about 3%.

The biggest local tax increase this year came from elementary school district 97.  The primary reason for its 4.1% increase relates to the continuing impact of an error made two years ago, when the school district received $2.6 million more from a referendum than it expected.  To make up for overtaxing two years ago, the school reduced its tax levies last year.  With a 4.1% tax increase this year, District 97’s overall levy is now close to the level it would have reached if the district had collected the correct amount of money in 2017, and then received inflation-level tax increases in the next two years.

If you are eligible for a homeowner, senior citizen or other exemption but did not receive one, the Township Assessor’s office can assist you in obtaining a revised bill for a smaller amount.  If you have received all exemptions for which you are eligible, you likely will not be able to do anything about your current bill.

Between July 1 and July 30, the Cook County Board of Review will be accepting appeals from Oak Park residents for next year’s taxes.  Residents may call the Oak Park Township Assessor’s office during the appeal period to schedule an appointment for help in preparing an appeal.  Alternatively, residents can get help at the end of the appeal period by attending a tax appeal seminar sponsored by the Board of Review.  The seminar will take place on July 30 at 6:30 PM at the auditorium of Percy Julian Middle School, located at 416 S. Ridgeland Avenue in Oak Park.
