Your Logan County Real Estate Tax Bill is determined by the following:


  • The assessed valuation during the previous year the county and township assessors established the value of your property. When this is completed the abstract is sent to the state who reviews the abstract and then places a multiplier (factor) which will either raise the valuation, lower the valuation or leave it the same.

  • When the assessor's work is completed the work is turned over to the Logan County Clerk whose job it is to extend the tax rates. The taxing bodies must file their levies with the county clerk by December before the bills are to be mailed. The county clerk divides the levy by the assessed valuation for that taxing body and this produces the rate necessary to bring in that levy. If the rate exceeds the rate limit as set by the state statutes the clerk can only use the limit so the taxing body will be unable to collect their full levy.

  • All parcels are located in a geographic area. The taxing bodies have different boundaries so they may overlap. For example you may live on one side of the street and pay to one school district and someone else may pay to another depending on that school boundary. Everyone pays county tax, township tax, road and bridge tax and except in east and west Lincoln townships a multi–township assessor tax. If you are in the country you could pay into one fire district and your neighbor into another. The taxing bodies you pay into determine your rate.

  • The total tax rate is multiplied by the equalized assessed value of the property and this produces the amount of the tax.
