Community development

" Tax expenditures-exclusions, credits, deductions, deferrals, and preferential tax rates-are one tool the government uses to promote community development. Multiple tax expenditures contribute to community development. GAO (1) identified community development tax expenditures and potential overlap and interactions among them; (2) assessed the data and performance measures available and used to assess their performance; and (3) determined what previous studies have found about selected tax expenditures' performance. GAO identified community development activities using criteria based on various federal sources and compared them with authorized uses of tax expenditures. GAO reviewed agency documents and interviewed officials from the Internal Revenue Service (IRS) and five other agencies. GAO also reviewed empirical studies for selected tax expenditures, including the New Markets Tax Credit and Empowerment Zone program which expired in 2011. "
