NTD Uniform System of Accounts (USOA)
The Uniform System of Accounts (USOA) is the basic reference document for the National Transit Database. It contains the accounting structure required by Federal Transit laws (previously Section 15 of the Federal Transit Act). Federal Transit Administration (FTA) implemented minor structural changes to the accounting requirements and reporting system in a Federal Register notice published on October 11, 2016. This document is the updated USOA, reflecting the changes published in the Federal Register on October 11, 2016 and should be used for NTD reporting beginning in FY18.
