The National Taxpayer Advocate Purple Book presents a concise summary of 71 legislative recommendations that the National Taxpayer Advocate believes will strengthen taxpayer rights and improve tax administration.
“Over the past five years, I have had the opportunity to closely observe the extraordinary amount of planning, coordination, and sustained effort required each year to deliver a successful filing season. Filing season is not a single event; it is a year-round undertaking that depends on the alignment of technology, staffing, training, legal guidance, and operational execution across the IRS that begins six to 12 months before the start of the filing season. When this alignment works well, taxpayers experience predictability and timely service. When it does not, the consequences are immediate and sometimes financially devastating.”
Erin M. Collins, National Taxpayer Advocate
Each year’s Annual Report to Congress identifies the ten most serious problems facing taxpayers and offers recommendations to fix them. These issues can affect taxpayers’ basic rights and the ways they pay taxes or receive refunds, even if they are not involved in a dispute with the IRS. As your Voice at the IRS, the National Taxpayer Advocate uses the Annual Report to elevate these problems and recommend solutions to Congress and the highest levels of the IRS.
This section discusses the ten federal tax issues most frequently litigated during the preceding year and contains an analysis of cases petitioned in the Tax Court rather than simply decided cases, providing a much broader view of issues taxpayers bring to court.
In this section, TAS reports on its 2025 advocacy updates from its Case Advocacy and Systemic Advocacy functions.
The Taxpayer Advocate Service (TAS) is an independent organization within the IRS. Led by the National Taxpayer Advocate, TAS is your Voice at the IRS.
The National Taxpayer Advocate’s Annual Report to Congress identifies taxpayers’ problems and provides suggestions to further protect taxpayer rights and ease taxpayer burden.
The National Taxpayer Advocate delivers this report directly to the tax-writing committees in Congress (the House Committee on Ways and Means and the Senate Committee on Finance), with no prior review by the IRS Commissioner, the Secretary of the Treasury, or the Office of Management and Budget.
The Executive Summary provides an overview of the National Taxpayer Advocate 2025 Annual Report to Congress and the 2026 Purple Book.
