The Jasper County Assessor's office is located in the County Courthouse in Rensselaer, Indiana.

The Office of the Jasper County Assessor is responsible for accurately and uniformly determining the market-value-in-use of every property in the county while serving the public with integrity in a helpful, professional and knowledgeable manner. This is achieved by using three approaches to value: Cost, Income, and Sales Comparison. The State now requires annual adjustments of assessments to reflect changes in the market. We encourage you to contact us with any questions or concerns regarding your assessment.
