Ways to pay less

Nothing here applies to every house automatically. These are worth checking:

  • Seniors 65+: senior homestead exemption

    The senior exemption reduces equalized assessed value by $5,000 in counties other than Cook and those next to it.

  • Seniors 65+ with household income of $75,000 or less: assessment freeze

    The freeze is open to people at least 65 with household income of $75,000 or less for taxable year 2026 (payable in 2027).

    How: File Form PTAX-340 each year with the county assessment office.

How these numbers are made
  • Property tax uses Williamson County's 2025 District Rates by Taxcode, code 01003 (Carterville, John A. Logan College 530, Carterville Unit 5, Anne West Lindsey Library): 7.47666 per $100 of EAV.
  • Starting value is one third of the Data USA median ($197,100 / 3) since Illinois assesses at 33 1/3 percent of fair cash value; the $6,000 general homestead exemption comes off it.
  • Water: the 2026 rate sheet (inside city): $29.30 minimum covers the first 2,500 gallons, modeled as $11.72 per 1,000 gallons for the first 2.5 kgal; then $8.44, $6.69, $5.79, $5.33 and $4.92 per 1,000 gallons in successive blocks of 5,000, 7,500, 15,000, 70,000 and over 100,000 gallons. Fixed $9.00 = $3.00 capital meter charge plus $6.00 bond charge. Sewer: $22.00 monthly plus $5.00 per 1,000 gallons. Trash $18.84 monthly (the city's Waste page still shows an older $17.59).
  • Electric: Homefield 11.378 cents plus Ameren delivery (4.572 and 2.427 cents) and riders; the city electric tax (0.401 cents per kWh, first 2,000 kWh, Carterville City Code 36-5-1, 2020 codification; read from the page image because OCR drops a digit) is added to both tiers; Ameren's collection add-on is not modelled. Part of Carterville is served by Egyptian Electric Cooperative. Gas: Ameren distribution plus gas charge. NOT INCLUDED: insurance.
