Students in the Federal Tax Clinic represent low-income taxpayers in controversies with the IRS, both before the IRS and in federal court. Students may also work on Massachusetts Department of Revenue cases in addition to their federal cases. Students will work individually and in teams to represent taxpayers involving examinations, administrative appeals, collection matters and cases before the United States Tax Court and Federal District Courts. Students will represent taxpayers with the goal of maximizing financial wellbeing and protecting taxpayer rights, including securing refunds and credits to which taxpayers are entitled, providing relief from joint and several liability for innocent spouses, and reducing tax liabilities through successful negotiated resolutions or compromises of liabilities based upon taxpayer financial hardship.
The Clinic provides a singular opportunity to have extensive client contact, to conduct fact investigation and legal research, and to develop, present, and argue cases on behalf of vulnerable taxpayers who would otherwise not have access to justice. Because the Clinic teaches lawyering skills applicable across numerous practice areas, students are encouraged to enroll whether they have an existing interest in tax law and practice or simply seek an immersive law practice experience through which they can learn valuable skills and provide pro bono representation to those in need.
In addition to representing local clients, the Clinic looks to comment on proposed rules and regulations impacting low income taxpayers, and it looks to litigate broadly on issues impacting this community as well as to file amicus briefs on issues of importance.
