Building an AI Toolkit for Audit and Tax (4066): This 1-unit, mandatory pass course provides a hands-on introduction to the use of artificial intelligence in audit and tax practice. Designed for law students but open to students in all schools, the course offers practical exposure to how AI tools are transforming white-collar professional services beyond traditional legal practice. The course consists of three intensive simulations: Session 1: Personal income tax simulation. Session 2: Corporate income tax simulation. Session 3: Audit simulation. In each session, students will use AI tools to complete realistic professional tasks. Students may use tools available through the law library (e.g., Harvey) and will also receive access to AI platforms designed specifically for accounting and audit functions that are not otherwise available to students (e.g., Accrual). Several of these accounting-focused tools are currently in development. When such tools are used in the simulations, the entrepreneurs building them are expected to join the class to demonstrate their platforms, discuss design decisions, and engage with students about the evolving role of AI in audit and tax practice. This course is particularly well suited for students who: Want practical exposure to AI tools used in white-collar professions beyond law; Plan to work in tax law, securities law, corporate governance, or in-house roles interacting with finance and accounting teams; or Seek to understand how AI will reshape auditing, tax compliance, and financial oversight. No technical background is required. Elements used in grading: Series of reflection papers (no exam).
