There hasn’t been much good economic news in recent years, but one bright spot for the economy is that the United States is a haven for foreign investors and this has helped attract more than $10 trillion to American capital markets according to Commerce Department data.

These funds are hugely important for the health of the U.S. financial sector and are a critical source of funds for new job creation and other forms of investment.

This is a credit to the competitiveness of American banks and other financial institutions, but we also should give credit to politicians. For more than 90 years, Congress has approved and maintained laws to attract investment from overseas. As a general rule, foreigners are not taxed on interest they earn in America. Moreover, by not requiring it to be reported to the IRS, lawmakers on Capitol Hill have effectively blocked foreign governments from taxing this U.S.-source income.

This is why it is so disappointing and frustrating that the Internal Revenue Service is creating grave risks for the American economy by pushing a regulation that would drive a significant slice of this foreign capital to other nations. More specifically, the IRS wants banks to report how much interest they pay foreign depositors so that this information can be forwarded to overseas tax authorities.

Yes, you read correctly. The IRS is seeking to abuse its regulatory power to overturn existing law.

Not surprisingly, many members of Congress are rather upset by this rogue behavior.

Senator Rubio, for instance, just sent a letter to President Obama, slamming the IRS and urging the withdrawal of the regulation.

At a time when unemployment remains high and economic growth is lagging, forcing banks to report interest paid to nonresident aliens would encourage the flight of capital overseas to jurisdictions without onerous reporting requirements, place unnecessary burdens on the American economy, put our financial system at a fundamental competitive disadvantage, and would restrict access to capital when our economy can least afford it. …I respectfully ask that Regulation 146097-09 be permanently withdrawn from consideration. This regulation would have a highly detrimental effect on our economy at a time when pro-growth measures are sorely needed.

And here’s what the entire Florida House delegation (including all Democrats) had to say in a separate letter organized by Congressman Posey.

America’s financial institutions benefit greatly from deposits of foreigners in U.S. banks. These deposits help finance jobs and generate economic growth… For more than 90 years, the United States has recognized the importance of foreign deposits and has refrained from taxing the interest earned by them or requiring their reporting. Unfortunately, a rule proposed by the Internal Revenue Service would overturn this practice and likely result in the flight of hundreds of billions of dollars from U.S. financial institutions. …According to the Commerce Department, foreigners have $10.6 trillion passively invested in the U.S. economy, including nearly “$3.6 trillion reported by U.S. banks and securities brokers.” In addition, a 2004 study from the Mercatus Center at George Mason University estimated that “a scaled back version of the rule would drive $88 billion from American financial institutions,” and this version of the regulation will be far more damaging.

Both Texas Senators also have registered their opposition. Senators Hutchison and Cornyn wrote to the Obama Administration earlier this month.

We are very concerned that this proposed regulation will bring serious harm to the Texas economy, should it go into effect. …Forgoing the taxation of deposit interest paid to certain global investors is a long-standing tax policy that helps attract capital investment to the United States. For generations, these investors have placed their funds in institutions in Texas and across the United States because of the safety of our banks. Another reason that many of these investors deposit funds in American institutions is the instability in their home countries. …With less capital, community banks will be able to extend less credit to working families and small businesses. Ultimately, working families and small businesses will bear the brunt of this ill-advised rule. Given the ongoing fragility of our nation’s economy, we must not pursue policies that will send away job-creating capital.We ask you to withdraw the IRS’s proposed REG-14609-09. The United States should continue to encourage deposits from global investors, as our nation and our economy are best served by this policy.

Their dismay shouldn’t be too surprising since their state would be especially disadvantaged. Here are key passages from a story in the Houston Chronicle.

Texas bankers fear Mexican nationals will yank their deposits if the institutions are required to report to the Internal Revenue Service the interest income non-U.S. residents earn. …such a requirement would drive billions of dollars in deposits to other countries from banks in Texas and other parts the country, hindering the economic recovery, bankers argue. About a trillion dollars in deposits from foreign nationals are in U.S. bank accounts, according to some estimates. …The issue is of particular concern to some banks in South Texas, where many Mexican nationals have moved deposits because they don’t feel their money is safe in institutions in Mexico. …”This proposal has caused a wave of panic in Mexico,” said Lindsay Martin, an estate-planning lawyer with Oppenheimer Blend Harrison + Tate in San Antonio. He has received in recent weeks more than a dozen calls from Mexican nationals and U.S.-based financial planners with questions on the rule. …Jabier Rodriguez, chief executive of Pharr-based Lone Star National Bank, said not one Mexican national he has spoken to backs the rule. “Several of them have said if it were to happen, then there’s no reason for us to have our money here anymore,” he said. Many Mexican nationals worry that the data could end up in the wrong hands, jeopardizing their safety. If people in Mexico and some South American nations find out they have a million dollars in an FDIC-insured account in the United States, “their families could be kidnapped,” added Alex Sanchez, president of the Florida Bankers Association.
