We strongly encourage our residents to utilize online, mail, or drop box options to conduct business. I assure you that all work is a priority at the Clinton County Treasurer's Office. Please feel free to call our office at 563-244-0573 with questions. An echeck is cheaper than a stamp!!! I will continue to advocate for reducing fees for online transactions, but we need to change the law before we can get it to be free. Thank You!
