The following information, including links and contact information, are resources to help you with questions and concerns you may have regarding the Internal Revenue Service (IRS) and federal taxes.  If you cannot find the information you are looking for, or need further assistance, please do not hesitate to contact one of my state offices and a member of my staff will be happy to assist you.

Taxpayer Advocate

The Taxpayer Advocate's Office is an independent organization within the IRS established to protect the rights of the taxpayers.  The Taxpayer Advocate service offers, free, independent, and confidential advice to taxpayers who have not been able to solve their problems through the normal IRS channels.  If action by the IRS will prevent you from providing for necessities such as housing, transportation, or food, you may request the assistance of the Taxpayer Advocate.

Please note:  The Taxpayer Advocate should only be contacted after you have tried to resolve your tax related issue through normal IRS channels (below).

What is Casework?
