IAAO has released the results of the Property Tax Policy and Administration (PTPA) survey as a follow-up to the 2017 Property Tax Assessment Policies and Practices Survey (PTAPP) and the results of the survey were released in the Fall 2025 issue of the Journal of Property Tax Assessment Administration.
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.
