Your assessment may be higher than the current market supports, or you may be missing exemptions that reduce taxable value. Lower Property Tax reviews the property, compares available market data, and prepares a packet you can print, sign, and mail.
Local property tax update
Cook County homeowners often face very different assessment issues depending on whether the property is in Chicago or a nearby suburb, making exemption status and comparable sales especially important.
For Cook County, compare your property against homes in the same local market whenever possible instead of relying only on broad Illinois trends.
What affects your bill
Local property tax bills are driven by assessed value, the tax rate, exemption eligibility, and county appeal rules. Comparable sales and property condition issues may help support a lower assessment.
