Financial Audit: IRS's Fiscal Years 2006 and 2005 Financial Statements

Because of the significance of Internal Revenue Service (IRS) collections to overall federal receipts and, in turn, to the consolidated financial statements of the U.S. government, which GAO is required to audit, and Congress's interest in financial management at IRS, GAO audits IRS's financial statements annually to determine whether (1) the financial statements are reliable and (2) IRS management maintained effective internal controls. GAO also tests IRS's compliance with selected provisions of significant laws and regulations and its financial systems' compliance with the Federal Financial Management Improvement Act of 1996 (FFMIA).
