Detroit Economic Competitiveness Act - Amends the Internal Revenue Code to establish the Detroit Jobs Trust Fund to finance economic development in Detroit, Michigan. Requires the Secretary of the Treasury to make annual distributions from such Fund to the city of Detroit for payment of debt obligations and for job development, public safety, education, and business and public infrastructure.

Terminates such Fund five years after enactment of this Act.
Requires GAO to submit annual reports to Congress describing the use of distributions from the Trust Fund, the extent to which progress has been made in meeting the plan's development goals, and Comptroller General recommendations for improving the program established under this Act.
