The Taxpayer Advocate Service (TAS) is your voice at the IRS. We take this statement seriously, as demonstrated by the work we do to help taxpayers resolve their tax problems. We do more than resolve problems, however. Part of our mission is to recommend changes that will prevent problems in the future. And in keeping with that part of our mission, we provide oversight and support for the Taxpayer Advocacy Panel (TAP), a federal advisory committee made up of citizens that listens to taxpayers, identifies major taxpayer concerns, and makes recommendations for improving IRS customer service and customer satisfaction.
