Failing to pay your tax obligations can lead to major consequences. One problem you might run into is that you may not be able to obtain a U.S. passport or renew an existing passport. Carrying tax debt could also keep you from using your already issued passport. This can be detrimental for those who need to travel internationally for work or family reasons.

The IRS has prioritized the enforcement of this consequence of not paying back taxes for the past year. The law targets those with “seriously delinquent tax debts,” which is defined as a debt of $52,000 or more, including taxes, penalties, and interest.

If the IRS identifies you as being seriously delinquent, it will inform the State Department, which by law will deny a passport application or renewal. If you have in your possession a valid passport, the State Department also has the power to revoke the passport or limit your ability to leave the United States.
