Requires the Director: (1) within 180 days, to issue guidance to agencies on the use and implementation of the single data standard for information required to be reported to agencies by the private sector; (2) within one year, to develop the single data standard required for use by federal agencies for federal financial information; and (3) within 18 months, to issue guidance to agencies on the use and implementation of the single data standard.

Directs each agency head to ensure that information collected using the single data standard is accessible to the general public.

Requires the Director, within one year, to submit to the House Committee on Oversight and Government Reform and the Senate Committee on Homeland Security and Government Affairs a report on the status of the implementation of this Act.
