Tax Administration: Costs and Uses of Third-Party Information Returns

One proven approach for improving tax compliance is information reporting to the Internal Revenue Service (IRS) by third parties about taxpayers' income and expenses. IRS matches information returns with taxpayers' income tax returns to see if taxpayers have filed returns and reported all their income. The administration's fiscal year 2008 budget proposed requiring information reporting on merchant payment card reimbursements and on certain payments to corporations, raising an estimated $18.4 billion over 10 years. This report's objectives are to (1) identify, using case studies, the compliance costs of existing information reporting; (2) determine the kinds of third-party compliance costs that may result from the two budget proposals and options for mitigating the costs; and (3) determine IRS's ability to process and use additional information returns. GAO did nongeneralizable structured interviews with four payers volunteering information and with five companies filing a sizable percentage of all information returns. GAO's work also included reviewing studies and documentation and contacting other government and nongovernment parties.
