Half of real estate and mobile home taxes must be paid by September 30th. Washington County Treasurer Jeff Garrett explains a penalty of 1.5% per month, rounded to the nearest whole dollar, with a $ minimum per parcel will be attached beginning October 1st. Payments must be accompanied by statement coupons. To avoid a late penalty, payments should be mailed with a postmark date of September 30th or before.

Payments may also be made in person at the treasurer’s office in the Washington County Courthouse or online at iowatreasurers.org. Tax payers can also drop off payment in the drop box by the south entrance of the courthouse.
