Vendor and Accounts Payable Information

The Sangamon County Treasurer's Office is responsible for maintaining vendor information and paying vendors via check or ACH. Sangamon County requires all vendors to complete and send to us a W-9 before payments are made to a vendor. In addition to the W-9, Sangamon County prefers to pay vendors via ACH whenever possible to reduce the cost of payment. Vendors should also complete a Vendor ACH form to sign up for this payment method. The vendor forms are available below. Vendors may e-mail completed forms to TRSFINREQ@Co.sangamon.il.us or fax them to 217-753-6837 or mail them to Sangamon County Treasurer's Office, 200 S. Ninth St, Room 102, Springfield, IL 62701.
