Enrolling in a tax relief program does not hurt your credit score. If you continue to ignore your tax problems, the IRS may eventually place a tax lien on your assets. While this does not affect your credit score, tax liens can appear on public records searches, which many creditors, landlords, and employers routinely monitor.

However, enrolling in a tax relief program like an Installment Agreement may prevent a public notice of federal tax lien from being filed in certain circumstances.
