Property tax assessments are being sent out this week. Some assessments will reflect changes due to rising market values in Black Hawk County and across Iowa. The Assessor’s Office is required to update assessed values based on sales data. An explanation of how assessed values are determined can be found here: https://blackhawkcounty.iowa.gov/DocumentCenter/View/7790/2025-Website-Assessment-Information_03312025
An increase in assessed value does not necessarily indicate an increase in property taxes. The rollback and levy rate set by taxing bodies (cities, school, county) next spring will determine tax amounts. These new values are for the 2025 assessment and will affect the fall 2026 tax bill. Property owners who have concerns about their assessments can request an informal review or appeal to the Board of Review.
