Legal Internship Program

The MTC gave me opportunities that made my resume a standout. As an extern, I helped staff legislative projects, put together a professional lecture, contributed to a brief and a published article, and met attorneys who continue to mentor me to this day. No other firm or organization could have given me this type of experience.

Externing with the MTC allowed me to immediately work on projects that had real-world impact.  I contributed to several briefs, helped put together presentations, and performed research for ongoing litigation. The experience proved invaluable when I worked in the private sector after getting an LL.M in tax. After a few years, it was great to return to the MTC as counsel and continue working on what I think are the most interesting and important projects in state taxation.

The MTC welcomes inquiries from law students, including those seeking an LL.M. in taxation, about working as a legal intern during the summer or during any school semester. We will work with you to obtain course credit and provide a unique opportunity for you to work on real-world, cutting-edge, state and local tax issues from a government perspective.The MTC Legal Division consists of the General Counsel and attorneys with decades of experience in state tax administration, tax litigation, and tax accounting. Two of our current attorneys were externs with the MTC before joining our team.

We always need help addressing issues that arise during audits of large multistate businesses; providing litigation assistance to public sector attorneys who are drafting appellate briefs or preparing for oral argument; and researching and writing about issues related to the development of uniform laws and regulations that have a national impact.

Additionally, MTC attorneys are frequently preparing for presentations, developing training materials, writing articles, drafting amicus briefs, and working on legal issues that support the work of the MTC. They also provide staff support to the UniformityLitigationAudit, and SITAS Committees, which meet in person multiple times a year across the country and are open to the public. 

If you are selected as a legal intern at the MTC, you’ll have the chance to discuss and participate in all these matters as part of our team.


The MTC is headquartered in Washington, DC but we do not require interns to be located in the District. All MTC attorneys except the General Counsel work remotely from locations across the country.
