The Washington County Treasurer would like to remind residents that the second half real estate and mobile home taxes were due March 1st and must be paid by April 1st to avoid penalty. On April 2nd, the penalty of 1 1⁄2% per month (rounded to the nearest whole dollar with a $1.00 minimum) will be attached. In order to reduce wait times and provide the best service possible, the county treasurer encourages payments to be mailed to the Washington County Treasurer at PO Box 889, Washington, Iowa, 52353, placed in the drop box located by the west door of the courthouse, or paid online at www.iowatreasurers.org. Statement coupons must accompany payments.  Payments sent by mail must have a US Postal Service postmark date of April 1st or earlier to avoid penalty. Predated checks will not be accepted as a substitute for the proper postmark. Taxes remaining unpaid on May 31, 2024, will be advertised as delinquent, and those remaining unpaid on June 17, 2024, will be offered at the annual tax sale. Contact the treasurer’s office at 319-653-7721 for more information or for help with alternate payment methods.
