The Ohio Inspector General says Stuart Davis, the Department of Administrative Services chief information officer, requested the money from CGI Technologies and Solutions for a 2013 corporate event in Cincinnati.
An Inspector General's report released Thursday says Davis had signed and approved state contracts with the company.
The report says Davis denied to investigators that he solicited the sponsorship fee.
A spokesman says the Administrative Services Department respects the watchdog's role and is reviewing the report carefully. A message seeking comment was left with Davis.
The Inspector General is forwarding the report to Columbus and Franklin County prosecutors and to the Ohio Ethics Commission.
This story has been corrected to reflect the questioned fee was for sponsorship, not speaking.
