Maricopa County Chief Deputy Assessor Timothy L. Boncoskey becomes President of the International As


Timothy L. Boncoskey, the Chief Deputy Assessor under Maricopa County Assessor Paul D. Petersen, took on the role of President of the International Association of Assessing Officers (IAAO) as of January 1, 2019 as the second Arizonan to do so.

Chief Deputy Assessor Boncoskey will lead the nearly 8,000 assessment professionals interested in property valuation and taxation across the globe in their mission to promote innovation and excellence in property appraisal, assessment administration and property tax policy.

The IAAO continues to be the forum to discuss and set industry standards on emerging technology such as integrating drones and more geographic data into property appraisals. As President, Chief Deputy Assessor Boncoskey will help guide these discussions and bring back best practices that will benefit the Maricopa County community.

This act of service comes on top of over a decade of volunteerism in the professional field. Chief Deputy Assessor Boncoskey has served in the IAAO since joining then-Maricopa County Assessor Keith E. Russell’s administration in 2006. He also serves on the National Association of Counties (NACo) Board of Directors and previously served 17 years in various positions in Arizona’s State government.

The inauguration of Chief Deputy Assessor Boncoskey is just one of many examples of why the Maricopa County Assessor’s Office has a reputation for innovation and leadership in property assessment.

Under Maricopa County Assessor Paul D. Petersen and Chief Deputy Assessor Tim Boncoskey, the Assessor’s Office has adopted its award-winning Legal Class Verification and Desktop Review Programs, launched its first fully digital forms and promoted electronic statements. All of which save taxpayers money and provide more convenient service to the public.
