You must file Form 130 with the Lake County Assessor by this date, along with any supporting evidence for your appeal. Missing this deadline means you cannot appeal your assessment for that tax year.
How do I file a property tax appeal with Lake County's PTABOA?
To file an appeal with Lake County's Property Tax Assessment Board of Appeals (PTABOA), complete Form 130 and submit it to the Lake County Assessor at Building A, 2nd Floor, 2293 N.

What is the homestead deduction worth in Lake County?
The standard homestead deduction in Lake County reduces your assessed value by $48,000, plus an additional supplemental deduction of 35% of the assessed value (up to $3,000 maximum). For a home valued at $135,400, these deductions would reduce your taxable assessed value significantly, saving approximately $700-800 per year in property taxes. You must own and occupy the property as your primary residence as of January 1 to qualify.
What happens at a Lake County PTABOA hearing?
At a Lake County PTABOA hearing, you'll present your case for why your property assessment should be lowered. You can attend in person at the Lake County Training & Media Center, participate by telephone, or simply submit your evidence for review. Most cases based on recent purchases or professional appraisals can be resolved without appearing. The board reviews your evidence, hears from the assessor's representative, and makes a decision. You'll receive written notification of their decision by mail.
How much can I save by appealing my property taxes in Lake County?
The amount you can save depends on how much your assessment is reduced. With Lake County's 1.37% effective tax rate, every $10,000 reduction in assessed value saves approximately $137 per year. For example, if your appeal reduces your home's assessed value from $150,000 to $135,000, you would save about $205 annually. Many successful appeals achieve reductions of 5-20% when supported by strong evidence like recent comparable sales or professional appraisals.
What evidence do I need for a successful Lake County property tax appeal?
For a successful appeal in Lake County, gather evidence such as recent sales of comparable properties in your neighborhood (within the last 6-12 months), a professional appraisal from an Indiana-licensed appraiser, photographs showing property condition issues, repair estimates from licensed contractors, or documentation of errors on your property record card. The Lake County Comparable Grid tool at https://assessor.lakecountyil.gov can help you find comparable sales. The stronger your evidence, the better your chances of a reduction.
Can I appeal my Lake County property taxes every year?
Yes, you have the right to appeal your property tax assessment every year in Lake County. Even if you appealed last year, you can file a new appeal if you believe your property is still overassessed. Each year's appeal must be filed by the June 16th deadline with current evidence. Many property owners successfully appeal multiple years when market conditions change or new comparable sales become available.
