No one likes getting mail from the IRS. In recent balance due notices sent by the IRS they are including a paragraph that says at the top in BOLD letters. Denial or Revocation of United States passport. In December of 2015 congress passed the FAST act which includes a provision allowing for the revocation of a passport for a person with seriously delinquent tax debt. There are various conditions that need to be met in order to meet the definition of “seriously delinquent tax debt.” One of those provisions is that the tax debt must exceed 50,000. Yet, I just got a notice for a client owing $142.64 that included that warning. IRS notices can be confusing and difficult to understand. If you need help dealing with an IRS notice you can get competent advice from a tax professional such as an Enrolled Agent to represent you before the IRS.
