Farmland Valuation Cards  - Assessment Year 2018

A parcel of land used for agricultural purposes for two years may be eligible for farm assessment. Farmland is assessed based on its agricultural economic value rather than being based on 33 1/3 percent of its market value, as is other property.


The mapping department assesses farmland in the county based upon use. We work closely with the assessors to verify land use so that we can properly assign land types to the soil types within a parcel. The Illinois department of Revenue provides guidelines found in Publication 122.


Farm buildings are assessed at 33 1/3 percent of their contributory value of the farm. Township assessors assess farm home sites and residences at 33 1/3 percent of their market value.


State of Illinois instructions for farmland assessment are found on their publication PUB-122 using the following link:

Information on Preferential Assessments on Wooded Acreage is found using the following link:
