Illinois has lifted the income ceiling for its senior property-tax freeze to $75,000 for the 2026 tax year, up from $65,000, opening the benefit to a larger group of older homeowners. The change applies to the Low-Income Senior Citizens Assessment Freeze Homestead Exemption, a program that locks the assessed value of a qualifying home in place so that rising property values do not drive up the tax base. The higher limit widens eligibility, but the freeze protects only the assessment, not the final bill.
What the higher limit changes for 2026
The freeze is available to homeowners who are 65 or older during the tax year and who own and occupy the property as their principal residence. The qualifying figure is total household income, and raising that cap to $75,000 brings in seniors whose Social Security, pension, and modest investment income had pushed them just past the old $65,000 line. For those households, crossing back under the ceiling can mean holding their assessed value steady rather than watching it climb with the local market.
The figure that decides eligibility is household income, counted broadly. It generally includes Social Security, pension and annuity payments, wages, interest, dividends, and taxable withdrawals from retirement accounts for everyone living in the home, not only the applicant. That breadth is why the increase from $65,000 to $75,000 matters: a two-person household with combined retirement income near the old cap can now qualify where a single large withdrawal or a cost-of-living raise had previously pushed it over the edge and out of the program.
The increase was enacted through state legislation that Illinois signed into law in December 2025, and it is scheduled to rise further in later years, to $77,000 for 2027 and $79,000 for 2028 and after. County assessment officials have publicized the shift, with one office confirming that the maximum household income rose to $75,000 for 2026. The program itself is administered statewide under the Illinois Department of Revenue, though applications run through each county.

What the freeze actually locks, and what it does not
The name of the program invites a common misunderstanding. The freeze holds the home’s equalized assessed value at a base-year amount, the figure the tax rate is applied to, but it does not freeze the tax rate or the dollar amount of the bill. If local taxing districts raise their levies or rates, a homeowner with the freeze can still see the bill increase, because the protection covers only the assessment and not the price of local government.
The mechanics rest on a base year. When a homeowner first qualifies, the county records the property’s equalized assessed value for that year, and the freeze holds the taxable assessment at that figure in later years even as the market value of the home rises. If a neighborhood’s values jump, the frozen owner is assessed as though the home were still worth its base-year amount, while an unfrozen neighbor is taxed on the higher current value. The wider the gap between the two, the more the freeze is worth.
The practical value therefore depends on where a senior lives. In an area of fast-rising home values, holding the assessed value at a base year can shield a homeowner from a large share of what would otherwise be a growing tax base. In a district that leans on rate increases to fund schools and services, the same freeze delivers a smaller cushion. County guidance stresses that the exemption freezes the assessed value rather than the tax bill.
The annual filing that trips seniors up
The freeze is not automatic once granted. Illinois requires eligible seniors to file Form PTAX-340 with their county each year, reporting household income to confirm they still fall under the limit. A homeowner who qualifies but forgets to renew can lose the exemption for that year even without any change in circumstances, an administrative step that quietly costs households the benefit more often than an income disqualification does.
Applying the first time runs through the local assessment office rather than the state. A senior submits the exemption application to the county supervisor of assessments or chief county assessment officer, documenting age, ownership, occupancy, and household income for the prior year. Because counties administer the program, filing deadlines and the exact paperwork can differ from one county to the next, and a homeowner who relocates must establish a new base year at the new residence rather than carrying the old one along.
The freeze can also sit alongside other relief rather than replacing it. Eligible seniors may still claim the standard senior homestead exemption, which reduces assessed value separately, so the freeze is layered on top rather than chosen instead. Because eligibility turns on combined household income, a spouse’s earnings, a one-time capital gain, or a required retirement withdrawal can lift a household above the ceiling in a given year and interrupt the freeze until income falls back under the limit.
For fixed-income owners watching property taxes rise, the higher ceiling is a meaningful expansion, and the scheduled increases through 2028 signal that the state intends to keep pace with income growth. The benefit still comes with conditions worth understanding plainly: it caps assessed value rather than the bill itself, its value varies with local rates, and it survives only for homeowners who file the required form every year.
