Last Friday, General Accountability Office Comptroller David Walker strongly urged a "strategic, long range, and integrated" examination of tax expenditures to test their relevance and priority during a time when the federal budget is experiencing increasing strains. His comments came during the unveiling of a new GAO report recommending that the OMB and the Treasury take steps to ensure greater transparency of, and accountability for, tax expenditures. Walker emphasized to reporters, as he has in the past, the importance of putting the nation on a more "prudent and sustainable course for the long term." He insisted that doling out tax preferences has an impact on the government's bottom line, and at a time when we are experiencing high deficits, it is important to reevaluate some of those expenditures.
