This bill amends the Internal Revenue Code of 1986 to authorize the National Taxpayer Advocate to appear as an amicus curiae in Federal tax cases. This new authority allows the Advocate to present views on issues that broadly affect the rights of taxpayers , particularly those outlined in the Taxpayer Bill of Rights. Federal courts are mandated to grant the Advocate's application to appear in such actions, ensuring their participation in significant legal proceedings. This expansion of the Advocate's role aims to provide a voice for taxpayer interests in the judicial system. The amendment will take effect upon the date of the bill's enactment.
