Why are Residential Property Tax Rates Regressive?

Abstract

Among single-family homes that enjoy the same set of property tax-funded amenities and pay the same statutory property tax rate, owners of cheap houses pay almost 50% higher effective tax rates than owners of expensive houses. This pattern appears throughout the United States and is caused by systematic assessment regressivity—cheap houses are over-assessed relative to expensive houses.

I use an instrumental variable approach to show that a large portion of this pattern can be attributed to measurement error in sale prices. Sixty percent of the remaining regressivity can be explained by tax assessors' flawed valuation methods that ignore variation in priced house and neighborhood characteristics and 40% by infrequent reappraisal. A simple valuation method can alleviate assessment regressivity and increase poor homeowners' net worth by more than 10%.

This paper was presented by Natee Amornsiripanitch on February 18, 2022 as part of the 2021-2022 Syracuse Webinar Series on Property Tax Administration and Design.

This Syracuse-Chicago Webinar Series on Property Tax Administration and Design aims to gather insight and scholarship through domestic and international comparative studies with common threads to help reform and improve property tax administration and design in the U.S. and other countries facing similar problems.
