Homestead Tax Deductions and Home Values: The Case of Washington DC Versus Maryland

In Washington DC, homeowners benefit from a generous homestead property tax deduction, which significantly reduces their property tax burden. This deduction specifically exempts a substantial portion of home assessment values from taxation. To understand the causal effects of this policy on home values, this article examines the impact of an increase in DC homestead tax deductions. The increase was implemented as a policy decision to index the homestead deduction to the Consumer Price Index starting from 2013. In the absence of a comparable property tax policy change in Maryland around the relevant years, we utilize this policy based natural experiment and compare the home value increases in the census tracts along the DC-Maryland border. Our findings reveal that this policy led to an economically and statistically significant increase in estimated home value in DC tracts compared to neighboring tracts in Maryland. Moreover, our results indicate that this effect is even more pronounced in neighborhoods with a majority Black population, thereby highlighting the potential redistributive implications of such tax policies.
