California’s State-County Assessors’ Partnership Agreement Program (SCAPAP) provided select counties with a dollar-for-dollar matching grant from the state for assessment administration over a three-year period from fiscal year 2015 through 2017. One of the policy goals for the grant was to finance administrative activities that would lead to an increase in the property tax base, thereby increasing property tax revenue. This study evaluates how well the grant accomplished this goal. Using the synthetic control method on data from 2007 through 2018, I find little evidence SCAPAP funds increased participating counties’ property tax base. Since the purpose of the program is based on sound economic theory, I caution interpreting this conclusion as a reason to discontinue policy experimentation.
