Illinois seniors earning up to $75,000 in household income will qualify for the state’s property-tax assessment freeze starting in tax year 2026, a $10,000 jump from the current $65,000 cap. The governor signed SB 642 into law as Public Act 104-0452, and county assessor offices from Cook to Effingham have already begun posting the new threshold. The higher limit will show up on property tax bills issued in 2027, giving eligible homeowners a locked equalized assessed value, or EAV, on their primary residence.
Why the $75,000 senior freeze threshold changes the math for 2026
The Senior Citizens Assessment Freeze Homestead Exemption, known as SCAFHE, works by holding a qualifying home’s EAV at the level recorded the year before the homeowner first received the benefit. That frozen valuation shields seniors from rising assessments, but it does not cap the actual tax bill. Local taxing districts can still raise rates, which means the dollar amount owed can climb even while the assessed value stays flat. The state tax-relief page spells out this distinction on its PIO-74 guidance, listing the SCAFHE household-income limit as $75,000 or less for taxable year 2026, payable in 2027.
The previous $65,000 ceiling excluded seniors whose incomes fell between $65,000 and $75,000, a band that includes many retirees drawing Social Security alongside modest pensions or part-time wages. By widening the window, Public Act 104-0452 pulls that group into the program for the first time. The measure also builds on language in HB1563 that ties future annual income limits to the Consumer Price Index for All Urban Consumers, or CPI-U, so the cap should adjust with inflation in subsequent years instead of remaining flat for long stretches.
For homeowners living on fixed incomes, the effect can be substantial. When assessments rise sharply in a single reassessment year, seniors without the freeze see their taxable EAV jump in lockstep, even if their income barely moves. Under SCAFHE, once a homeowner qualifies, their EAV is frozen at the base-year level as long as they continue to meet age, ownership, occupancy, and income rules. Over multiple cycles, that can mean paying taxes on an assessed value that is thousands of dollars lower than the market-based figure on neighboring properties that do not qualify.
Counties that move quickly to explain the change stand to capture a larger share of newly eligible applicants. Rock Island County, Effingham County, and McHenry County have already published simple year-by-year income tables on their websites to show how the new limit phases in. Cook County Assessor Fritz Kaegi called the update relief “for more senior homeowners who have worked hard to stay in their homes.” Counties that post only a brief legal notice without context risk leaving eligible residents unaware of the deadline or confused about what the freeze actually covers, especially given the common misunderstanding that the program freezes the total bill rather than the underlying assessment.
How county outreach and application deadlines shape who benefits
The Cook County Assessor’s Office lists a May 15, 2026 application deadline on its program page, along with documentation requirements for income verification and occupancy. Seniors must prove that their total household income, including Social Security and other nontaxable sources, falls at or below $75,000. The office also reiterates the core program mechanic: the freeze applies to EAV, not to the tax bill itself, so applicants should not expect their total payment to remain unchanged if local tax rates rise.
Outside Cook County, local assessor offices set their own outreach cadence. McHenry County has encouraged seniors to apply early and has confirmed the $75,000 income figure for 2026 in its public materials. Effingham County has highlighted the change in its senior outreach sessions, emphasizing that first-time applicants in the $65,000-to-$75,000 band will need to gather income statements for every member of the household, not just the person listed on the deed. In Rock Island County, assessors have stressed that seniors who previously missed the cut because they were a few thousand dollars over the old limit should re-check their eligibility for the 2026 tax year.
Because SCAFHE is not automatic, the size of the benefit pool will depend heavily on how clearly counties communicate the new rules. Offices that send direct mailers, host in-person help days, and partner with senior centers are likely to see higher participation than those that simply update a web page. Advocates note that many older homeowners are uncomfortable submitting income documentation online or are unsure which forms count, so in-person or phone assistance can make the difference between a successful application and a missed opportunity.
For seniors and their families, the practical takeaway is straightforward: confirm that the property is a primary residence, verify that at least one owner will be 65 or older in 2026, total up all household income to see if it falls at or below $75,000, and then check the local assessor’s deadline and filing instructions. With assessments rising in many parts of Illinois, locking in a lower EAV for 2026 could help more older homeowners stay in their communities, even as tax rates continue to shift in the years ahead.
