Generate an Illinois senior citizen property tax exemption appeal demand letter. State-specific, statute-based, ready to file with your county assessor or BOR.
Generate My Letter — $19If you are an Illinois homeowner age 65 or older and your county assessor denied or removed your Senior Citizens Homestead Exemption or Senior Assessment Freeze, Illinois law gives you a clear path to fight back. The Illinois Property Tax Code protects qualifying seniors from inflated tax bills by reducing assessed value and, in some cases, freezing it. But denials happen often—missed paperwork, income verification errors, or assessor mistakes. A timely, well-drafted appeal letter to your Chief County Assessment Officer or county Board of Review can restore your exemption and trigger a refund of overpaid taxes. This page explains the Illinois statutes, deadlines, and strategies that make senior exemption appeals successful, and helps you generate a letter tailored to your county.
Illinois provides two key property tax breaks for seniors. The Senior Citizens Homestead Exemption under 35 ILCS 200/15-170 reduces the equalized assessed value (EAV) of an owner-occupied home by $8,000 in Cook County and $5,000 in all other counties for homeowners 65 or older. The Senior Citizens Assessment Freeze Homestead Exemption under 35 ILCS 200/15-172 freezes the EAV at the base year amount for seniors 65+ with household income at or below the statutory cap (currently $65,000), preventing increases tied to rising property values.
To qualify, the applicant must (1) be 65 or older during the assessment year, (2) own or have a legal/equitable interest in the property, (3) use it as a primary residence, and (4) be liable for the property taxes. The freeze exemption additionally requires annual income certification on Form PTAX-340.
When an assessor denies an exemption, the homeowner may appeal first to the Chief County Assessment Officer, then to the county Board of Review under 35 ILCS 200/16-55. If still unsatisfied, the taxpayer can appeal to the Illinois Property Tax Appeal Board (PTAB) under 35 ILCS 200/16-160 or file a tax objection complaint in circuit court under 35 ILCS 200/23-5. Cook County operates on a township-by-township appeal calendar; downstate counties follow a 30-day window after the Board of Review publishes assessments. A demand letter that cites the correct statute, attaches proof of age, ownership, residency, and (for the freeze) income, often resolves the issue without formal litigation.
An effective Illinois senior exemption appeal letter does three things: identifies the legal basis, documents eligibility, and demands a specific remedy within a stated timeframe. Address the letter to the Chief County Assessment Officer or Board of Review clerk for the county where the property is located. Open by citing 35 ILCS 200/15-170 or 15-172 and the parcel index number (PIN). State the tax year(s) at issue and the specific action being challenged—denial, removal, or failure to apply the exemption.
Next, methodically establish each statutory element: attach a copy of a driver's license or birth certificate proving age 65+, a recorded deed or trust agreement showing ownership, a utility bill or voter registration confirming primary residency, and—for the assessment freeze—Form PTAX-340 with income documentation (Social Security statements, 1099s, tax returns). If a prior exemption was wrongly removed, reference the year it was first granted.
Close with a clear demand: reinstate the exemption for the current and any improperly billed prior years, issue a corrected tax bill or refund through the county collector, and respond in writing within 30 days. Note your intention to escalate to the Board of Review, PTAB, or circuit court if the matter is not resolved. Send by certified mail, return receipt requested, and keep copies of all enclosures. A documented paper trail strengthens any later PTAB hearing and signals that you understand your rights under the Property Tax Code.
Illinois Board of Review appeals must generally be filed within 30 calendar days of the published assessment notice; Cook County uses rolling township deadlines posted by the Assessor and BOR. PTAB appeals must be filed within 30 days of the Board of Review's final decision. There is no filing fee at the Board of Review or PTAB for residential appeals. Tax objection complaints in circuit court require payment of the disputed tax under protest and standard civil filing fees (varies by county). The Illinois small claims limit is $10,000, but property tax exemption disputes are not handled in small claims—they proceed through administrative channels first. Refund claims for prior years are generally limited to the certificate of error process under 35 ILCS 200/14-15.
Property tax in Illinois is governed by the Illinois Property Tax Code (35 ILCS 200/1-1 et seq. (appeals: 35 ILCS 200/16-160; PTAB: Article 16, Div. 5)). Assessment cycle: General (quadrennial) reassessment every four years in most counties; Cook County reassesses on a triennial (three-year) cycle by geographic triad. Assessment date is January 1 of the tax year. Assessed value: 33 1/3% (one-third) of fair market value statewide (the Illinois Department of Revenue targets a 33.3% level of assessment). Cook County uses classification: approximately 10% for residential and 25% for commercial/industrial, reconciled via a state equalization multiplier.
Illinois Department of Revenue (state oversight/equalization); county Boards of Review and township/county assessors (local); Illinois Property Tax Appeal Board (PTAB) for statewide appeals. The window to act is short — board of Review: within 30 days of publication of the township assessment list (deadlines vary by county/township). Property Tax Appeal Board (PTAB): petition must be postmarked within 30 days of the Board of Review's final written decision; faxed/emailed appeals not accepted.
A recent change to watch: 2025-2026 reforms: General Homestead Exemption maximum set (up to $10,000 for 2025, with 2026+ indexed to lesser of 5% or CPI); Senior Freeze income limit raised from $65,000 (2025) to $75,000 (2026). Property tax debt/tax-sale reform (2026 legislation) aimed at helping homeowners retain equity, extending Cook County's annual tax-sale schedule.
Exemptions to claim: General Homestead Exemption (up to $10,000 EAV in Cook County / $6,000 in other counties for 2026); Senior Citizens Homestead Exemption ($5,000, age 65+); Senior Citizens Assessment Freeze (income limit raised to $75,000 for tax year 2026); Returning Veterans' Homestead Exemption ($5,000 for two years); Disabled Veterans' Standard Homestead Exemption ($2,500 for 30-49% disability, $5,000 for 50-69%, total exemption for 70%+); plus Home Improvement and Persons with Disabilities exemptions.
First-level appeal: County Board of Review (BOR) — a quasi-judicial body providing an informal venue to resolve assessed-value disputes (some counties allow an informal review with the township/county assessor first). In Cook County, an initial appeal may be filed with the Cook County Assessor before the Board of Review.
Appeal deadline: Board of Review: within 30 days of publication of the township assessment list (deadlines vary by county/township). Property Tax Appeal Board (PTAB): petition must be postmarked within 30 days of the Board of Review's final written decision; faxed/emailed appeals not accepted.
Next-level appeal: Illinois Property Tax Appeal Board (PTAB) — a five-member statewide quasi-judicial body; alternatively, taxpayers may seek judicial review by filing a tax objection complaint in the circuit court. PTAB decisions are reviewable by the Appellate Court under the Administrative Review Law.
Grounds you can raise: Overvaluation (assessment exceeds 33 1/3% of fair market value) and lack of uniformity/assessment inequity (property assessed higher than comparable properties). Decisions are based on equity and the weight of the evidence (35 ILCS 200/16-160).
Evidence that works: Comparable sales, comparable assessments (equity/uniformity grids), recent independent appraisals, a recent arm's-length purchase price, and documentation of property condition or income/expense data. PTAB weighs comparables by similarity in age, design, size, and features.
How your value is assessed: 33 1/3% (one-third) of fair market value statewide (the Illinois Department of Revenue targets a 33.3% level of assessment). Cook County uses classification: approximately 10% for residential and 25% for commercial/industrial, reconciled via a state equalization multiplier.
The hearing: Board of Review: informal hearings (written submission or in-person). PTAB: appeals may be decided on written evidence submissions; a formal in-person or telephonic hearing may be requested. The Illinois Supreme Court has affirmed that payment of the tax is NOT a prerequisite to appeal to PTAB.
