National Enterprise Zone Act of 2007 - Amends the Internal Revenue Code to direct the Secretary of the Treasury to designate areas in the United States and its possessions as National Enterprise Zones and to publish a list of such Zones. Requires a Zone to: (1) have more than 50,000 residents; (2) have a poverty rate of two times the national poverty rate; and (3) have an unemployment rate two times the national average.
Allows corporate and noncorporate taxpayers with taxable income from an active trade or business within such a Zone to elect a reduced alternative income tax in lieu of existing income and alternative minimum tax rates.
Requires the Secretary to study and report to Congress on the effectiveness of such program.
