Clark County Auditor John Federer was installed as President of the Southwest District of the CAAO




Clark County Auditor John Federer was installed as President of the Southwest District of the County Auditors’ Association of Ohio (CAAO) for 2017 at their annual Winter Conference.  Also installed were Vice President Greene County Auditor David Graham and Secretary/Treasurer Pickaway County Auditor Melissa Betz.  The Honorable C. Douglas Chamberlain of Logan County installed Mr. Federer during a ceremony on Thursday, November 17th at the Embassy Suites Dublin.


The District works closely with the CAAO Columbus office to monitor legislative proposals that impact local taxpayers and to offer initiatives that assist County Auditors in carrying out their duties.   During 2017 we anticipate much activity as the state begins the process of enacting a new biennial budget, with ongoing examination of government reform measures, major changes in a variety of taxation issues, and addressing the general condition of the state’s economy.


The CAAO includes all 88 Ohio County Auditors.  Now entering into its 150th year, it was established to promote and protect the interests of the taxpayers of Ohio and to improve the administration of county government.



Clark County Auditor Continues to Refine Fair and Accurate Real Estate Taxes

This year, 2016, is the Triennial Appraisal Update which is required for Clark County. As Auditor John S. Federer explains, “This is not a total reevaluation whereby the Auditor examines every parcel in each part of the county. Rather, a triennial update is a review of neighborhood values based upon actual sales over the prior three years. This project has been in process since February of this year, and values will be updated for both agricultural and residential properties throughout Clark County.”

The Auditor is announcing an “Open Book” session being conducted from September 12 through October 14. During this time, property owners will be able to obtain information regarding their values by stopping in the Auditor’s Office at 31 N. Limestone Street, Springfield, Monday through Friday, from 8:00 a.m. to 4:30 p.m., or by calling (937) 521-1878.

“My staff and I have worked very hard to ensure that property values are fair and accurate for all taxpayers in Clark County,” said Auditor Federer. Updated values will be reflected in the January 2017 tax bills.
