PROPERTY ASSESSMENT IN INDIANA
By

Hendricks County Assessor
This is the first in a series of articles to help explain the why and how real property (real estate) is
assessed in Indiana and Hendricks County. The assessing of property for tax purposes is rooted in the
practices used in England for centuries by Kings and Queens to secure funding for the government
activities and services.
Hendricks County became a county in 1824. The first reference to assessing we have been able to find
in county records is to James Parks in 1843 who had the title of “County Lister” or as is now known as
the County Assessor. The term Lister is only used today in the state of Vermont.
In 1999, the Indiana Supreme Court ruled that Indiana’s property tax system was unconstitutional. The
General Assembly then took action to move the state to a market-based assessment program or system.
The term market value-in use was determined by the legislature to be the true-tax value for tax
assessment purposes. This action resulted in Indiana joining forty-eight (48) other states in using a
market- based assessment system.
Prior to 2002 real estate in Indiana was assessed primarily based on cost, especially the initial cost of
improvements such as buildings, houses and barns. Depreciation was applied periodically to the
improvements which in turn reduced the overall value of the parcel or property, for tax purposes.
Resale value or market value was not taken into consideration. Over several decades this caused great
differences in the value of similar properties for tax purposes.
Each year since 2002 county assessors in Indiana have striven to determine an estimate of market value-
in use for each parcel of real property in their respective counties. Our goal each year as determined by
the Indiana State Department of Local Government Finance (DLGF) is to estimate the taxable market
value- in use within five percent (5%), plus or minus; of the amount an owner could reasonably expect to
receive if selling on the date of assessment.
All counties in Indiana use a method called “Mass Appraisal” to help determine estimates of value.
Neighborhoods or market areas of similar type properties are identified. Properties are similar but not
identical in their characteristics. Recent sales in neighborhoods and market areas are evaluated to help
in identifying trends of value for each market area or neighborhood. Other methods used to help in
estimating values and market trends would be the cost to build the improvements and by using property
income data if appropriate.
The reason for using the mass appraisal method versus individual property appraisals in determining
estimates of value is a matter of cost. Using Hendricks County as an example: As of January 1, 2017 we
have 70,500 parcels in total real estate ranging from agriculture land to residential to commercial to
industrial to vacant land. The cost for individual appraisals each year would range from $300 to $20,000
plus, per parcel. Using a possible average of $1,000 per parcel per professional appraisal, the County
