TAS identifies systemic issues in multiple ways; for example, Systemic Advocacy closely collaborates with TAS Case Advocacy to identify trends through reviews of TAS casework and outreach events. TAS also identifies problems via public submissions to the Systemic Advocacy Management System (SAMS) database and the National Taxpayer Advocate and Deputy National Taxpayer Advocate’s relationships with internal and external stakeholders. TAS employees serve on various internal working groups and collaborative teams with the IRS. This allows TAS analysts to recognize potential systemic issues and advocate for changes before they become a problem. This proactive approach helps protect taxpayer rights and ensures that the IRS considers and minimizes taxpayer burden. Additionally, TAS’s Systemic Advocacy teams partner with external stakeholders including TAP and LITCs to learn about problems facing taxpayers.
