How the tax is worked out
As an illustration of the arithmetic: at Kootenai County's derived rate of 0.47%, a home valued at $400,000 would carry a tax bill of roughly $1,884 a year. That is only an illustration using the derived rate — a real bill is computed from the property's assessed value, its exemptions, and the combined rates of its specific taxing districts, so it can be higher or lower.
The usual sequence is: the local assessor values the property; exemptions are applied; the taxable value is multiplied by the combined local rates; and the county bills and collects the tax, distributing it to the schools, municipalities and districts that levied it.
