The Coal City School Board last week approved filing an assessment complaint against GE Hitachi.
Superintendent Kent Bugg said GE Hitachi is located on Dresden Road in Grundy County.
Bugg said several of the assemblies are coming from out of state.
The school district believes the property is under assessed.
Bugg said the Grundy County Board of Review will hear about the complaint.
Bugg believes other taxing districts could also file an assessment complaint.
