Some senators think they have found a way to get around the problem of international hackers stealing the tax information of American citizens. Unfortunately, that plan is to have the United States simply turn over that information whenever a country that has signed up to international treaties on taxes requests it. Sen. Rand Paul (R-Ky.) has put a hold on the plan, with the intention to protect the Constitution, American taxpayers, businesses, and the nation’s economic health by blocking these dubious treaties. Far from benign agreements, these tax accords are significant threats to the United States. One in particular, the Convention on Mutual Administrative Assistance, is particularly troublesome.
