Overview of Assessments

Annual Adjustments

Annual Adjustments or “trending” of property values became part of Indiana’s move to a market-based assessment system that began in 2002.

Trending requires assessors to research sales of properties in a particular area over the previous two years. Using that information, assessors then estimate the values of other properties in the same area to determine an assessed value.

Please see our Fact Sheet for more information on Annual Adjustments.

Ratio Study Approval Information

As part of the Annual Adjustment process, counties are responsible for submitting a ratio study and uniformity for all classes of property in all townships. The ratio study measures the accuracy and equity of assessments. It is determined by the formula: Assessed Value/Sale Price = Ratio. The assessment ratio for all properties in Indiana is to be 100%.

The accuracy of assessments refers to how close the assessments determined by local assessing officials are to market value-in-use.

See County Specific Information for your county’s Ratio Study.

Real Property Guidelines

The 2011 (sic 2012) rule and manual applies to the reassessment process, used by Indiana Assessors, for the 2012 pay 2013 property tax year. By statute, the Department of Local Government Finance adopted this new rule change July 1, 2009; however, due to a legislative delay, the reassessment commenced July 1, 2010. The 2011 (sic 2012) rule replaces the language used as part of the 2002 reassessment rule and manual. The 2011 (sic 2012) rule applies the appropriate "True Tax Value" definition for assessing property.

The Department has released updated cost schedules for use in the 2013 annual adjustment. Further updates will be released on an annual basis.
