Who Gains and Who Pays? Property Tax Burden after Wildfires in California

• In Event: After the Fire: Economic and Institutional Responses to Wildfires

Abstract

Wildfires have become more frequent and destructive in recent years as climate change intensifies both hazard exposure and economic damages. Beyond their immediate physical and social impacts, wildfires can substantially reshape local public finance by altering the property tax base, the primary revenue source for many local governments. While aggregate fiscal effects have received growing attention, far less is known about how wildfire shocks redistribute property tax burdens across homeowners.Property tax liabilities may adjust after a wildfire through several distinct channels. Wildfires can destroy housing stock, depress local housing demand, and induce outmigration, all of which affect market values. At the same time, institutional features, such as assessment rules, reassessment triggers, and post-disaster tax relief programs, mediate how these market changes translate into tax liabilities. As a result, property tax burdens may diverge from underlying property value changes.These dynamics are particularly salient in California, where both wildfire risk and institutional complexity are high. The state experiences billions of dollars in wildfire damages annually. At the same time, California’s property tax system, which is anchored by Proposition 13, creates a unique environment in which assessed values are based on historical purchase prices and grow only gradually unless properties are sold. For example, homeowners who relocate after a wildfire may face substantially higher tax liabilities if they purchase replacement homes at current market prices, effectively increasing their tax burden despite experiencing a loss.Conversely, a series of reforms, including Proposition 50, Proposition 171, and Proposition 19, have expanded the ability of affected homeowners to transfer their existing tax base to replacement properties, potentially mitigating tax increases. In addition, California’s Misfortune and Calamity Property Tax Relief program provides temporary reductions in assessed value for damaged properties, offering short-term relief. Taken together, these policies imply that wildfire impacts on property taxation are not uniform: some homeowners may benefit from relief or tax base portability, while others, particularly those in nearby but undamaged areas or those who move without qualifying for relief, may experience relative increases in tax burden.In this paper, we examine how wildfire events reshape the distribution of property tax burdens across homeowners in California. We compile a comprehensive, parcel-level dataset covering property assessments and housing transactions for residential properties statewide over the past two decades. Our analysis explicitly incorporates California’s institutional framework, including Proposition 13, subsequent tax base transfer policies, and disaster-related tax relief programs. We distinguish between directly affected homeowners and those in nearby exposed areas who may experience property value declines without corresponding tax adjustments. To complement the empirical analysis, we conduct interviews with county assessors and assessment officials to better understand the administrative implementation of these policies.By focusing on who benefits and who bears the burden, our study provides new evidence on the equity implications of property taxation under increasing climate risk. These findings have direct relevance for the design of disaster recovery policies and for ensuring that property tax systems remain both efficient and equitable in the face of growing environmental shocks.
