State and provincial property tax policies and administration (PTPA): 2023 findings and report
Since 1990, IAAO has published comprehensive surveys of property tax systems in the U.S. and Canada. The 2023 update is different in many ways to the prior surveys in that it included participants from outside North America and is the longest, most comprehensive survey in the series. There is an abundance of information on property tax systems available due to the work by groups such as the Lincoln Institute of Land Policy, which conducts their own comprehensive studies, but this survey attempts to capture some additional nuance, and we rely on the depth of expertise from our volunteer members to guide us. Because of the existence of multiple surveys across time, we are able to show how these policies and administration have evolved over time and are now able to contrast North American policy against a varied international dataset we hope to broaden in the future
Comparing and contrasting property tax oversight systems - Idaho and The Netherlands
Property tax system administration may occur at national, sub-national, or local levels and includes identification and valuation of taxable property, establishing tax rates, and billing and collection of taxes. Regardless of the initial assignment of responsibilities for these functions, both internal and external oversight are crucial to: • Providing accountability; • Maintaining public trust; • Ensuring compliance with laws; • Producing a transparent property tax system. Although much of this can be accomplished by internal quality control mechanisms, the existence of an oversight body operating independently from the valuation agency or those responsible for the tax components enables such independent corroboration of adherence to laws and good principles and practices. This type of multi-layered system exists in many places and this paper presents two such models – one in the State of Idaho in the United States and the other in The Netherlands - including the evolution of each system and how each system relates to guidance provided by the International Association of Assessing Officers (IAAO)
Harvesting AI: A Practitioner\u27s Perspective
In this seminar, students will learn AI valuation, AI Image Detection, and AI Data Collection, distinguishing traditional CAMA from AI valuation. The session focus includes variance testing and identifying where AI is effective and not effective. We will use case studies, variance tests, and a live Turing Test using SLIDO technology

Leveraging AI for Change Detection and Machine Learning in Property Assessment Workflows
The application of Artificial Intelligence (AI) for change detection has revolutionized property assessment, enabling assessors to efficiently identify changes in the built environment.
Now with AI and up-to-date imagery, you can create solutions that save time, money and resources that help your team identify and manage changes. With solutions such as change detection you can create repeatable processes and workflows that enlighten and expand the possibilities of your department.See how you can turn your GIS tool into a solution that can:
Be a source for taxable changes and increasing taxable revenue. Monitor the built environment with repeatable processes. Simplify digitizing building footprints and processes to identify change is city wide and done parcel by parcel
