Assessment Office

From Your Chief County Assessor

Our Mission Statement: To provide fair, accurate, and equitable assessments to all property owners in Rock Island County.

To All Rock Island County Taxpayers

Your township assessor is currently reviewing assessments for the 2025 year, which will be payable in 2026. If you would like to have your assessment reviewed, feel free to contact your township assessor.

Assessments are determined by your township assessor for a four-year period. The four-year period we are currently in is starting with the 2023 assessment year and will continue through the 2026 assessment year.

In the first year of the general assessment period, which is 2023, the Illinois Property Tax Code directs the township assessor "in person or by deputy (to) actually view and determine as near as practicable the value of each property listed for taxation as of January 1 of that year...."

The Property Tax Code informs assessment officials that the property record system shall include up-to-date and complete tax maps, ownership lists, valuation standards (calculation used to value your property) and property record cards, including appraisals, for all or any part of the property in the township. The township assessor maintains property record cards and are available by contacting your township assessor. These records are public records, and shall be available for public inspection during business hours, subject to reasonable rules and regulations of the custodian of the records.

In early fall, we will be mailing a notice of assessments to all taxpayers who receive a change in their 2025 assessment. This notice will provide you with your total assessment. See Assessment Changes.

These assessment changes will also be published in the Dispatch/Argus newspaper at the time of our mailing the assessment notice.

Should you have any questions about the assessment process, feel free to contact me.

On December 12, 2025, the Governor signed Senate Bill 642 into law, creating Public Act 104-0452, which increases the “maximum income limitation” for the Low-Income Senior Citizen Assessment Freeze Homestead Exemption (the “LISCAFHE”).  The change begins with the 2026 (payable 2027) year:

After the 2028 year, the maximum income limitation will remain at $79,000 unless it is changed by the General Assembly.

Whose income is included in Maximum Household Income?

By state law, Household Income means the combined income of the members of a household for the calendar year preceding the taxable year.

State law further defines a Household to include:

  • The applicant; and
  • The spouse of the applicant (even if the spouse resides elsewhere); and
  • All other persons using the residence of the applicant as their principal place of residence as of January 1 of the year for which the LISCAFHE is sought.

How is “Income” defined?

By state law, Income has the same meaning as provided in Section 3.07 of the Senior Citizens and Persons with Disabilities Property Tax Relief Act, except that it does not include veteran's benefits. The amounts that must be reported for each member of the household include:

  • Adjusted gross income, properly reportable for federal income tax purposes; plus
  • An amount equal to all amounts paid or accrued as interest or dividends during the taxable year;
  • An amount equal to the amount of tax imposed by the Illinois Income Tax Act paid for the taxable year;
  • An amount equal to all amounts received during the taxable year as an annuity under an annuity, endowment or life insurance contract or under any other contract or agreement;
  • An amount equal to the amount of benefits paid under the Federal Social Security Act during the taxable year;
  • An amount equal to the amount of benefits paid under the Railroad Retirement Act during the taxable year;
  • An amount equal to the total amount of cash public assistance payments received from any governmental agency during the taxable year other than benefits received pursuant to this Act;
  • An amount equal to any net operating loss carryover deduction or capital loss carryover deduction during the taxable year; and
  • An amount equal to any benefits received under the Workers’ Compensation Act or the Workers' Occupational Diseases Act during the taxable year.

When will the application forms with these changes be available?

LISCAFHE application forms for the 2026 (payable 2027) year will be mailed to all taxpayers who received the LISCAFHE around mid to late February. For first-time applicants, they will be available at https://www.rockislandcountyil.gov/, or can be mailed to taxpayers on request.

When will the applications be due back to the Assessment Office?

LISCAFHE application forms for the 2026 (payable 2027) year are due back in the Rock Island County Assessment Office no later than July 1, 2026.

What if I have further questions or need assistance?
