Correspondence issued by the Government Accountability Office with an abstract that begins "This letter responds to a Congressional request that we provide responses to questions related to our recent testimony before Congress on reauthorizing federal rail safety programs. Our testimony discussed how the Federal Railroad Administration (FRA) (1) focuses its efforts on the highest priority risks related to train accidents in planning its oversight, (2) identifies safety problems on railroad systems in carrying out its oversight, and (3) assesses the impact of its oversight efforts on safety. This testimony was based on our recent report on these topics."

Correspondence issued by the Government Accountability Office with an abstract that begins "The Internal Revenue Service (IRS) most recently estimated that the gross tax gap--the difference between what taxpayers pay in taxes voluntarily and on time and what they should pay under the law--reached $345 billion for tax year 2001. The tax gap arises when taxpayers fail to comply with their individual income, corporate income, employment, estate, or excise tax obligations through (1) underreporting of tax liabilities on tax returns; (2) underpayment of taxes due from filed returns; or (3) nonfiling, which refers to the failure to file a required tax return altogether or on time. IRS's tax gap estimates are based on a variety of data sources. Recently, IRS studied individual taxpayer compliance through the National Research Program (NRP), and used the resulting compliance data to estimate the tax gap for individual income tax underreporting and the portion of employment tax underreporting attributed to self-employment taxes for tax year 2001. NRP, which involved reviewing around 46,000 individual tax returns, has yielded very important new information on taxpayer compliance for the first time since IRS's previous compliance measurement study was undertaken for tax year 1988. Compliance measurement studies such as …

Testimony issued by the Government Accountability Office with an abstract that begins "The Federal Housing Administration (FHA) has seen increased competition from conventional mortgage and insurance providers. Additionally, because of the worsening performance of the mortgages it insures, FHA has estimated that its single-family insurance program would require a subsidy--that is, appropriations--in fiscal year 2008 in the absence of program changes. To help FHA adapt to the evolving market, proposed changes to the National Housing Act would allow greater flexibility in setting insurance premiums and reduce down-payment requirements. To assist Congress in considering the financial challenges facing FHA, this testimony provides information from recent reports GAO has issued and ongoing work concerning the proposed legislation that address different aspects of FHA's risk management. Specifically, this testimony looks at (1) FHA's management of risk related to loans with down-payment assistance, (2) instructive practices for managing risks of new products, (3) FHA's development and use of its mortgage scorecard, and (4) FHA's estimation of program costs."
