Buried in the 1,300 pages of last Friday’s new five-year, $305 billion Highway Bill is a provision that will affect more than transportation or infrastructure—a tax provision would allow the State Department to revoke or deny passports and international travel for tax debts of $50,000 or more where there is non-payment. Those affected will need to litigate in the Tax Court or District Court to get their privilege back. There is the potential for this to be fraught with problems—for example, in cases were federal tax liens are erroneously issued and the like. For the millions of US citizens living abroad, this could potentially restrict their freedom of movement (to say nothing of putting a crimp in their holiday travel plans).
