The Internal Revenue Service (IRS) is the agency which is responsible for collecting income taxes. Included under IRS's umbrella are your refunds, collection of unpaid or underpaid taxes, designation of tax exempt organizations. The agency is also empowered to withhold refunds for payment of the taxpayer's debts for such things as education loans and child support.
You can call their toll free number, 1-800-829-1040. You will go through an electronic list and eventually be directed to a representative who can assist you with most questions.
If you only need to know the status of your tax return you can call 1-800-829-4477.
If the 1-800 number hasn't helped you, the IRS has instituted a Taxpayer Advocate Service Office in Albuquerque which you can contact with your questions.
After you have used the above resources, if you feel that you were not given a satisfactory answer or that they were not able to help, you may contact our office. If we are going to contact IRS on your behalf, you will be asked to fill out an IRS personal authorization (English) (Espanol) form giving us permission to make inquiries on your behalf.
