All U.S. states permit local governments to recover unpaid property taxes through a tax lien foreclosure process. Tax relief policies can reduce household tax burdens and prevent the foreclosure of owner-occupied homes, but little is known about their use and effectiveness. Like other cities, Detroit, Michigan, experienced a rise in tax foreclosures following the 2008 deep recession. Michigan law requires cities to exempt low-income homeowners from some or all of their property tax obligation. Implementation of this policy, the Poverty Tax Exemption, nevertheless failed to protect many low-income homeowners from dispossession through tax foreclosure. State-mandated and locally-determined procedures placed the burden of learning about and applying for the exemption on financially stressed homeowners, restricting widespread access to this critical tax relief. Eliminating institutional barriers to tax relief can prevent many owner-occupied tax foreclosures, especially in cities where a high need for tax relief occurs under local conditions of fiscal austerity.
