The University of Texas System has reversed course and released its last three tax returns.
The UT System asked the state attorney general's office on whether the information was public, then withdrew the request and released the returns Wednesday.
The 15-campus UT system is being audited by the Internal Revenue Service. The filings list business income unrelated to the system's educational mission.
The system had $23.1 million in such income during the fiscal year that ended Aug. 31, 2008, such as for rental of the Erwin Center in Austin.
Salaries, supplies and other deductions offset the income, with no tax owed. A previous overpayment led the system to claim a $3.3 million refund in 2007 and a $200,000 credit for 2008.
