This page helps users complete a DeKalb County, Illinois property search by choosing the right official tool for tax, assessment, map, and recorded land record information.

Start with the DeKalb County Property Tax Inquiry for parcel and tax details, use DeKalb County Interactive GIS for map-based property research, and use the DeKalb County Land Records Search for recorded documents.

DeKalb County Property Tax Inquiry

The DeKalb County Property Tax Inquiry is the main online search for property tax and assessment details. It supports real estate and mobile home searches.

You can search real estate records with any of these fields:

  • Parcel number
  • Owner name
  • House number range
  • Street name
  • City
  • Sale price range
  • Sale date range
  • Township, tax district, property class, or neighborhood
  • Tax year range

For the best match, enter the parcel number or the owner’s last name as it appears on the tax bill.

  • Choose Real Estate Search or Mobile Home Search.
  • Enter one or more supported search fields.
  • Use broader search terms if the first search returns no match.
  • Review the property tax, assessment, sketch, and square footage information shown for the parcel.

Important: assessment details, sketches, and square footage are provided for general information and may need confirmation with the township assessor.

Parcel maps and GIS property data

Use DeKalb County Interactive GIS when the task is map-based. The county’s property data and maps page describes GIS tools for viewing and printing property information, creating parcel buffers, and reviewing map layers.

Map-based property research can help when you need to compare a parcel location with boundaries, land use, zoning, voting information, or tax map references.

COMPASS and property record searches

The county’s property records page also identifies Assessment & Property Tax Search-COMPASS and wEDGE Property Tax Inquiry as property search options. COMPASS supports searches by parcel number, name, and site address.

When searching by parcel number in COMPASS, enter the number without dashes. If a full name search does not work, reduce the search to a last name or fewer address details.

The DeKalb County Land Records Search is the public search system for recorded documents on file with the Recorder’s Office. It supports quick searches by document number, name, and PIN without dashes.

Advanced search options include grantor or grantee, subdivision, section/township/range, property address, parcel number, document type, remarks, document number, UCC number, referral document number, document number range, and date filed range.

Official copies: documents printed from the website are unofficial. Official documents may be acquired through the Recorder’s Office.

Address and PIN search limits

Illinois law prohibits recording property by common street address. The DeKalb County Clerk & Recorder’s office began indexing street addresses on May 6, 1988.

If an address search in Land Records Search does not find the record, search by PIN instead. The Property Index Number is the same as the parcel number on a tax bill or Assessment Change Notice.

Property tax payment note

The property tax inquiry system includes payment-related information. If paying without an original bill, include a $5.00 duplicate bill fee per parcel with the tax payment.

The same system also provides detailed payment instructions and tax year search options, which can help users confirm the correct parcel and tax year before paying.

Assessment Office and township assessor help

The DeKalb County Assessment Office maintains the parcel ownership record database, receives and analyzes township assessment rolls, applies exemptions, administers the Board of Review process, and certifies the assessment roll.

For missing or unclear assessment details, sketches, or square footage, contact the township assessor first. The county provides a township assessor directory with assessor names, phone numbers, emails, and mailing or office addresses.
