The mill levy is the tax rate applied to the assessed value. One mill is equal to one dollar per $1,000 of assessed value. Since 1996, Legislators and the Governor have reduced the statewide USD general levy from 35 mills to 20 mills. A mill levy is computed by dividing the portion of a taxing authority's budget, that which is funded by property tax, by the taxable assessed value in the taxing authority's service area.
