Property Tax Bills Across Dubuque County, Iowa
How are property tax bills calculated in Dubuque County, Iowa?
Property tax bills in Dubuque County are based on the assessed value of a home, not its market price alone. Local tax rates are applied to that assessed value to determine the final bill, so two homes with similar market values can still owe different amounts depending on their assessment and location.

A home with a median price of $218,000 may still face a wide range of tax bills across the county. The 25th percentile tax bill is $1,972, while the 75th percentile is $3,874 and the 90th percentile reaches $5,178. That spread shows how much taxes can vary based on assessed value and local levies. In Asbury, the highest median tax bill is $4,176, while Worthington has the lowest median tax bill at $2,120. For homeowners, these differences can have a meaningful impact on annual housing costs.
