Gannett Wisconsin Media reports the agency is probing why Butler has been raising money in Wisconsin over the last decade but has made only one annual filing.
The LeRoy Butler Foundation hasn't filed with the IRS since 2002, even though Butler continued raising money under that name through this year. A scholarship fund founded in 2009 had its tax-exempt status revoked after failing to file returns by 2012. The only return on file from Butler since 2002 is a short-form 2011 filing for the fund.
Gannett Wisconsin Media reports Butler didn't respond to an email inquiry. In a Facebook posting, however, he said his foundation is conducting an independent review of compliance with federal guidelines.
