The DC government collects revenue in a variety of ways from its residents, businesses, and the federal government. These revenues are used to fund the wide array of services provided by the District, from schools to health care to libraries to road construction. The DC government collected about $10.5 billion in revenue in fiscal year (FY) 2015, with the largest sources being local taxes and federal funds. Other sources include various non-tax revenues such as licenses, fees, and private grants and donations. Much of the city’s non-tax revenue is described as “special purpose” revenue because it is devoted to specific purposes.
