Assessment notices are sent in the spring each year and typically reach your mailbox by the middle of the month. Each property owner receives an assessment notice that contains both the market value and assessed value, along with an estimate of your property tax bill.

Property Tax Bills Across Columbia, Monroe County, Illinois
How are property tax bills calculated in Columbia?
Property tax bills in Columbia are based on the assessed value of a home and the local tax rate set by taxing authorities. When the market value of a property changes, the assessed value can change as well, which affects the final tax bill. Homeowners are taxed on the value assigned to their property, not on what they originally paid for it.
What factors are considered in the calculation? Local government budgets, school funding, and other public services all help determine the tax rate applied to a home’s assessed value. A higher assessed value or a higher tax rate can increase the bill, while a lower assessed value can reduce it.
How does this affect homeowners? For a home with a median price of $256,425, even small changes in assessment can make a noticeable difference. Property taxes can influence monthly housing costs and long-term affordability, so understanding how the bill is calculated is important for Columbia homeowners.
