Chart of Accounts (COA)

**UPDATED 4/2025 - COA Closures & Hierarchy changes - FY25 year-end timetable.**

The Chart of Accounts (COA) is a set of codes used to classify and record financial transactions in meaningful ways. It provides the structure for reporting and monitoring financial activity at Yale. The COA consists of segments and descriptive attributes that help the University organize financial information for:

• Internal reporting and financial management
• External reporting and compliance
• Effective management of restricted funds

Different COA segments tell us information such as:

• How an activity was funded
• Who is responsible for financial oversight of the transaction (i.e., which department incurred the expense or earned income)
• What is the activity in which the unit engaged (i.e., mission, line of business and detailed activities)
• How to “account” for something purchased or sold

Consistent use of the COA on transactions is crucial to enable consistent and meaningful reporting for faculty, staff, University leadership, and external users.
