Real Property Taxes


First half taxes are due by April 30. If payment is late, total amount of tax becomes delinquent resulting in interest and penalty calculated on entire amount due for the year. Second half taxes become delinquent after October 31. Postmarks are accepted as payment date. If total tax for the year is less than $50, the entire amount must be paid by April 30.

Your canceled check is your receipt. Checks accepted are subject to collection. Non-payment by bank voids receipt. Returned check charge $25. Resolution No. 217-1981 12/1/81.


Interest on delinquent tax is computed monthly from the date of delinquency to the date of payment at the rate per annum prescribed by law. (1% per month).


Penalty of three percent is assessed on the amount of tax delinquent on June 1 of the year in which the tax is due. An additional penalty of eight percent is assessed on the total amount of tax delinquent on December 1 of the year in which the tax is due.

When paying any delinquent tax after calculation date, contact this office 360-378-2171 for correct interest and penalty due. Delinquent payments received for incorrect amounts will be returned.
