Wacky! Only about 4,000 Chicago homeowners (of an estimated 200,000 who qualify) have applied for the city's [election year] Property Tax Relief Program so far.
If your 2008 property taxes went up (you would have received the bill in October 2009) and your household income is under $200,000, you qualify for a one-time rebate of between $25 and $200, in the form of a Visa check card. You've got to show you live in the home as your primary residence by Xeroxing a photo ID and sending in a copy of your tax bill. The deadline is March 31st. Read more about it here.
Update: We found some fine print in filling out the application -- "The property tax bill must indicate the Homeowner Exemption. The program is only for properties owner-occupied as of January 1, 2007."
