All property is required to be revalued every six years.
The last revaluation was completed in 1994. Real property taxes are payable annually or semiannually. Amounts paid by multi-county taxpayers are due September 20 of the year assessed. Public utility real and tangible personal property taxes collected in one calendar year are levied in the preceding calendar year on assessed values determined as of December 31 of the second year preceding the tax collection year, the lien date. Public utility property taxes are payable on the same dates as real property described previously.
