The Township Assessor is an elected position (4-year terms). The assessor must be certified by the state and meet the continuing education requirements. As assessor it is my job to value all the parcels within the township. After we have valued the property, we apply the assessed value, which is 33 1/3% of market value. The assessor's office also applies any exemptions for which property owners qualify. These exemptions include homestead exemptions, senior exemptions, senior freeze exemptions, and home improvement exemptions.

It is the responsibility of the assessor to pick up any new property and add it to the tax roles. This includes new homes and businesses, additions, or anything else that may add value to the property. We receive copies of permits from the nine municipalities and the county (unincorporated areas) within the Township. Some services the Assessor's Office provide are:

  • Assist appraisers, realtors, and homeowners with property information.
  • Supply names and addresses for properties applying for variances.
  • Assist seniors filing for senior homestead exemptions.
  • Notify seniors about exemptions through publications and mailings.
  • Free notary for Libertyville Township residents.
  • Provide information requested for assessment appeals.
  • Provide records of property sales within the Township.
  • Answer questions relating to assessments and the taxing process.
