IRS Needs to Further Enhance Internal Control over Financial Reporting and Taxpayer Data

This report assesses whether the financial and tax-processing systems used by the US Inland Revenue Service (IRS) are effective in ensuring the confidentiality, integrity, and availability of financial and sensitive taxpayer information. The IRS has a demanding responsibility in collecting taxes, processing tax returns, and enforcing US tax laws. It relies extensively on computerized systems to support its financial and mission-related operations and on information security controls to protect financial and sensitive taxpayer information. This report examines IRS information security policies, plans, and procedures.
