Property Tax Bills Across Bath, Mason County, Illinois
How are property tax bills calculated in Bath?
Property tax bills in Bath are based on the assessed value of a home, not the purchase price. Local taxing authorities apply their tax rates to that assessed value to determine the annual bill. The result can vary widely from one homeowner to another because the tax bill reflects both the home’s value and the local levy structure.
What factors affect the bill? Home value is the biggest driver, and homes with higher assessed values generally face larger tax bills. In Bath, the median home price is $46,558, and the median property tax bill is $1,619, which is below the national median property tax bill of $2,400 and the national median property tax rate of 1.02%.
How does this affect homeowners? A lower bill can help keep housing costs manageable, but even modest changes in assessed value or tax rates can affect what homeowners owe each year. Bills in the area can range from $772 at the 25th percentile to $3,141 at the 75th percentile, with the 90th percentile reaching $5,030.
