May 9, 2011; Source: Washington Post | In yet one more nonprofit related strategy for tax revenue development by local government, Mayor Vincent Gray of Washington, D.C., is proposing a 6 percent tax on tickets to local arts institutions. Those institutions argue that the tax will have the effect of driving patrons away not just from them but from the restaurants and other businesses that benefit from the arts groups presence. Petitions are being circulated online to dissuade the city from this measure. Federal institutions will, of course, be exempt from the measure.—Ruth McCambridge
