## Highlights

The Internal Revenue Service (IRS) is implementing three tax system changes during the 2007 filing season that potentially could impact compliance by taxpayers as well as IRS's service to taxpayers. These changes are (1) the telephone excise tax refund (TETR), which can be requested by all individuals and entities that paid the excise tax regardless of whether they have an obligation to file a tax return, (2) the option to deposit refunds into up to three accounts, hereafter referred to as the split refund option, and (3) the extension of some tax provisions that had expired, hereafter referred to as the extender provisions. Because the 2007 filing season may be complicated by these changes, the Senate Committee on Finance asked GAO to determine the effects of these changes on compliance and taxpayer service including (1) the number of individuals or entities affected by these changes, (2) how the changes were expected to affect compliance and the results of compliance activities to date, and (3) the impact of the changes on returns processing and taxpayer service. GAO analyzed IRS documents and data from IRS databases and interviewed IRS officials.
