Property Tax Bills Across Andover, Henry County, Illinois
How are property tax bills calculated in Andover?
Property tax bills in Andover are based on the assessed value of a home and the local tax rate set for Henry County and other taxing authorities. When a home’s market value changes, the assessed value can change too, which affects the final bill. The calculation reflects both the property’s value and the levy applied to it, so two homes with different values can owe very different amounts.
What factors are considered?
Home size, location, and market conditions all play a role in determining assessed value. In Andover, the median home price is $156,316, and the median property tax bill is $2,969. That amount is above the national median property tax bill of $2,400, showing that homeowners here often face a higher-than-average tax burden.
How does this affect homeowners?
Higher assessed values can lead to larger bills, which can increase monthly housing costs and affect long-term affordability. For many homeowners, even modest changes in value can meaningfully change what they owe each year.
