Testimony issued by the Government Accountability Office with an abstract that begins "Noncompliance does not have a single source but occurs across different types of taxes and taxpayers. For example, individual income tax accounts for the largest portion of the tax gap, but corporate income tax and employment tax are also significant. Further, misreporting by individuals involves business income, non-business income, deductions, and credits. The extent of misreporting depends on the extent to which income tax is withheld or reported to the Internal Revenue Service (IRS) by third parties. For example, nearly 40 percent, or $179 billion, of the 2006 gross tax gap is due to misreporting of non-corporate business income and related self-employment taxes. Much of this misreporting can be attributed to sole proprietors underreporting receipts or over-reporting expenses. Unlike wage and some investment income, sole proprietors’ income is not subject to withholding and only a portion is reported to IRS by third parties."

Testimony issued by the Government Accountability Office with an abstract that begins "In summary, we found that, between 1981 and 2010, the time it took OSHA to develop and issue safety and health standards ranged from 15 months to 19 years and averaged more than 7 years. Experts and agency officials cited several factors that contribute to the lengthy time frames for developing and issuing standards, including increased procedural requirements, shifting priorities, and a rigorous standard of judicial review. We also found that, in addition to using the typical standard-setting process, OSHA can address urgent hazards by issuing emergency temporary standards, although the agency has not used this authority since 1983 because of the difficulty it has faced in compiling the evidence necessary to meet the statutory requirements. Instead, OSHA focuses on enforcement activities—such as enforcing the general requirement of the Occupational Safety and Health Act of 1970 (OSH Act) that employers provide a workplace free from recognized hazards—and educating employers and workers about urgent hazards. Experiences of other federal agencies that regulate public or worker health hazards offered limited insight into the challenges OSHA faces in setting standards. For example, EPA officials pointed to certain requirements of the Clean …
