Winnebago County Property Assessment Process
Property assessment in Winnebago County follows the same rules as the rest of Illinois. Township assessors do the field work. They visit properties, check building permits, and set values based on what the land and structures are worth. The assessment date is January 1 each year. That is the lien date under 35 ILCS 200/, and it sets the value for tax purposes. All real property in Winnebago County gets assessed at 33 1/3 percent of fair market value.
Winnebago County is on a four-year assessment cycle. A full reassessment happens every four years with annual adjustments in between. Township assessors send out assessment notices in the spring or summer. You have 30 days from the notice date to file a complaint with the Winnebago County Board of Review if you think the value is wrong. The board reviews evidence from both sides and makes a ruling. If you still disagree, you can appeal to the Illinois Property Tax Appeal Board or file a case in circuit court.
Farmland in Winnebago County uses a different method. Under 35 ILCS 200/, farm parcels are valued based on soil productivity, not market sales. This means farm property records in Winnebago County show a much lower assessed value than what the land would sell for on the open market. The Supervisor of Assessments works with township assessors to make sure farm values follow the state formula.

Property Records and Illinois Tax Law
The Illinois Property Tax Code (35 ILCS 200/) controls how property gets assessed and taxed in Winnebago County. It sets the 33 1/3 percent assessment standard, defines how appeals work, and spells out the duties of township assessors and the Supervisor of Assessments. Property taxes in Illinois are paid in arrears. The bill you pay this year covers last year's assessment. In Winnebago County, tax bills go out in the spring and are due in two installments.
Under 35 ILCS 200/, all property in Winnebago County must be classified and valued by the township assessor. The Supervisor of Assessments then reviews the rolls to check for fairness. If values in one township are too high or too low compared to others, the county can apply an equalization factor to bring them in line. The Illinois Department of Revenue also sets a state equalization factor each year that applies to all Winnebago County property records. This factor makes sure assessed values across Illinois stay at the 33 1/3 percent target.
The Illinois Department of Revenue does not run property tax at the local level. But it sets rules that Winnebago County must follow. The department publishes guidance on exemptions, assessment methods, and appeal deadlines that affect every county in the state.
Note: Changes to 35 ILCS 200/ happen through the Illinois General Assembly, so check for updates if you are looking at older property records from Winnebago County.
