What the rate means here
At 1.98%, Sangamon County taxes property more heavily than the country as a whole, which sits at 0.98%. Houses here are worth $170,300, below the national $303,400. Part of any high rate is arithmetic rather than policy: a smaller tax base has to be taxed harder to raise the same money.
It ranks #35 of 97 Illinois counties by effective rate, against a statewide 2.07%, and #98 nationally. The state runs from 2.68% in Lake County down to 0.82% in Pulaski County.
The median home costs 2.3 times the median household income of $74,114, against 3.86 nationally, which is a comfortable ratio by American standards. 70.61% of occupied homes are owned rather than rented, and cheap housing relative to income is usually why. The county has 195,217 residents, which is small enough that the medians describe a reasonably coherent market.
