Property tax calculator: How much will Amendment 1 cost you?
See how much more you can expect to pay in property taxes if the first question atop Illinois’ ballot passes Nov. 8.
On Nov. 8, Illinois voters will find a constitutional amendment at the top of their ballot labeled “Proposed Amendment to the 1970 Illinois Constitution,” or Amendment 1 for short.
Find out what Amendment 1 could cost you using the calculator below.
How will amendment 1 affect your property tax bill?
This tool uses compound annual growth rates in the All-Transactions House Price Index by the Federal Housing Finance Agency for Illinois counties from 2010-2021 to project future home values through 2026. To project property tax bills through 2026, the tool uses the compounded annual growth rate in median property tax rates for Illinois counties, calculated using 1-year and 5-year U.S. Census Bureau American Community Survey estimates from 2010-2020.
This is a conservative estimate based on historical home price growth and projected property tax rates if government unions maintain the status quo. However, Amendment 1 would grant government union bosses the most extreme powers in the nation, including the ability to override state law.
If Amendment 1 passes, Illinoisans would be forced to fund the ever-increasing cost of these provisions. Should government union bosses exercise new powers granted through Amendment 1, the tax hike on Illinoisans could wind up being far more costly.
The measure would allow government unions to make demands outside the normal scope of bargaining, strike if their demands are not met, thwart simple, pro-taxpayer reforms, crowd out government services for special interest causes and exacerbate corruption in Illinois.
That endless loop of unlimited government union demands, higher government costs and rising taxes likely is why no other state has a similar amendment. Illinois voters will decide Nov. 8 whether to insert Amendment 1 into the state constitution, but what they truly will decide is the future of their property taxes.
