Audit the Pentagon Act of 2013

Audit the Pentagon Act of 2013 - Requires, on March 2 of FY2014 and each subsequent fiscal year, a 5% reduction in the discretionary budget authority of a federal agency that is identified by the Director of the Office of Management and Budget (OMB) as required to have an audited financial statement: (1) that has not submitted a financial statement for the previous fiscal year, or (2) whose statement has not received either an unqualified or a qualified audit opinion by an independent external auditor. Excludes from such reduction accounts for military, reserve and National Guard personnel and the Defense Health Program account of the Department of Defense (DOD). Authorizes the President to waive a reduction in discretionary budget authority if such reduction would harm national security or members of the Armed Forces who are in combat.

Requires a report to Congress listing required DOD reports that interfere with DOD's capacity to achieve an audit of its financial statements with an unqualified opinion.

Expresses the sense of Congress that: (1) congressional defense committees and DOD should not endanger the nation's troops by reducing wounded warrior accounts or vital protection for members of the Armed Forces in harm's way, (2) the valuation of legacy assets by DOD should be simplified without compromising essential controls or generally accepted government auditing standards, and (3) this Act should not be construed to require or permit the declassification of accounting details about classified defense programs and DOD should ensure financial accountability in such programs.
