From Citizens for Tax Justice:
Today Senator Paul is still blocking such treaties. Taking his efforts a step further, he has introduced a bill to repeal a major reform that clamps down on offshore tax evasion. That reform is the Foreign Account Tax Compliance Act (FATCA), which was enacted in 2010 as part of the Hiring Incentives to Restore Employment (HIRE) Act. Senator Paul says he opposes it because of “the deleterious effects of FATCA on economic growth and the financial privacy of Americans.”
His arguments are entirely unfounded and the only thing he is accomplishing is to help those illegally hiding their income from the IRS. FATCA basically requires taxpayers to tell the IRS about offshore assets greater than $50,000, and it applies a withholding tax to payments made to any foreign banks that refuse to share information about their American customers with the IRS.
For a country with personal income tax (like the U.S.), that kind of information-sharing is indispensible to tax compliance, as the IRS stated in its most recent report on the “tax gap”:
Overall, compliance is highest where there is third-party information reporting and/or withholding. For example, most wages and salaries are reported by employers to the IRS on Forms W-2 and are subject to withholding. As a result, a net of only 1 percent of wage and salary income was misreported. But amounts subject to little or no information reporting had a 56 percent net misreporting rate in 2006.
So why shouldn’t foreign banks that benefit from the business of U.S. customers report the assets they deposit to U.S. tax enforcement authorities? Without such reporting, people who have the means to shift assets offshore are able to evade U.S. income taxes, while the rest of us are left to make up the difference.
