You can get help with unresolved tax issues, order free publications and forms, ask tax questions, and get information from
the IRS in several ways. By selecting the method that is best for you, you will have quick and easy access to tax help.
The Taxpayer Advocate Service (TAS) is an independent organization within the IRS whose employees assist taxpayers
who are experiencing economic harm, who are seeking help in resolving tax problems that have not been resolved through normal
channels, or who believe that an IRS system or procedure is not working as it should. Here are seven things every taxpayer
should know about TAS:
-
TAS is your voice at the IRS.
-
Our service is free, confidential, and tailored to meet your needs.
-
You may be eligible for TAS help if you have tried to resolve your tax problem through normal IRS channels and have gotten
nowhere, or you believe an IRS procedure just isn’t working as it should. -
TAS helps taxpayers whose problems are causing financial difficulty or significant cost, including the cost of professional
representation. This includes businesses as well as individuals. -
TAS employees know the IRS and how to navigate it. We will listen to your problem, help you understand what needs to be done
to resolve it, and stay with you every step of the way until your problem is resolved. -
TAS has at least one local taxpayer advocate in every state, the District of Columbia, and Puerto Rico. You can call your
local advocate, whose number is in your phone book, in Pub. 1546, Taxpayer Advocate Service—Your Voice at the IRS, and on

clinics can provide multilingual information about taxpayer rights and responsibilities. For more information, see Publication
