Campton Township property tax appeal (Kane County, IL)

2026 appeal deadline

October 26, 2026

Each Kane County township has its own filing deadline, set when its 2026 assessment changes are published in a local newspaper. Complaints postmarked by the deadline count as filed on time.

Documents to gather

  • Your assessment notice or the township's published assessed value for your parcel (PIN)
  • The county's appeal/complaint form, completed and signed (filed online where the county requires e-filing)
  • 3–5 comparable homes nearby with lower assessed values per square foot (PIN, address, size, assessed value)
  • A recent appraisal or purchase closing statement, if you bought within about 3 years
  • Photos of condition problems or errors on your property record (wrong square footage, bathrooms, basement)

How to file in Campton Township

  1. 1

    Find your township's deadline

    Kane County sets each township's deadline when its assessments are published in the local newspaper. The full list is on the county's filing deadlines page.

  2. 2

    Talk to your township assessor

    Questions about your valuation go to your township assessor first — the Board of Review can only act after publication.

  3. 3

    Prepare your evidence

    For an overvaluation complaint, gather recent comparable sales. The Board's 2026 rules require disclosure of any recent sale of your property.

  4. 4

    File with the Board of Review

    File your complaint with the Kane County Board of Review at 719 S. Batavia Ave, Building C, Geneva before your township's deadline. Mailed complaints count as filed on the postmark date.

  5. 5

    Attend the hearing

    The Board notifies you of your hearing, reviews the evidence, and issues its findings. Further appeal goes to the Illinois Property Tax Appeal Board (PTAB).

Good to know

  • Talking to the Campton Township Assessor first is free and can fix simple record errors before you file.
  • If the Board of Review denies you, you can appeal to the Illinois Property Tax Appeal Board (PTAB) within 30 days of the Board's written decision.
