DeKalb County Township Assessors

Property values in DeKalb County start with the township assessors. Each township has its own assessor who visits properties, checks building permits, and sets the initial assessed value. Common townships in DeKalb County include Sycamore, DeKalb, Cortland, Genoa, and Malta. Your township assessor is the first person to contact if you have a question about why your value is set where it is.

Under 35 ILCS 200/, township assessors must set values at 33 1/3 percent of fair market value. They use recent sales data, property conditions, and market trends to arrive at the number. The Supervisor of Assessments in DeKalb County then reviews the rolls to make sure values are fair and consistent from one township to the next. If a township's values look out of line with the rest of the county, the office can apply adjustments to bring them back in step. The DeKalb County township assessors page has phone numbers and addresses for each assessor in the county.

How DeKalb County Assessments Work

The assessment date in DeKalb County is January 1 each year. That is the lien date under 35 ILCS 200/. It sets who owns the parcel and what the value is for that tax year. DeKalb County follows the four-year assessment cycle used by most Illinois counties outside of Cook County. A full reassessment happens every four years with annual adjustments in between to keep values current.

Assessment notices go out in the summer or early fall. You have about 30 days from the date on the notice to file a complaint with the DeKalb County Board of Review. The board hears your case, looks at your evidence, and decides if a change is warranted. Bring comparable sales data, photos, or an appraisal to support your argument. If the board's decision still does not satisfy you, the next step is the Illinois Property Tax Appeal Board or circuit court. Most cases in DeKalb County get resolved at the local level.

Farmland follows a different path. Under 35 ILCS 200/, farm parcels in DeKalb County are valued based on soil productivity rather than market sales. This keeps farm assessments lower than what the land might sell for on the open market, which is a big deal in an area with a lot of agriculture.
