Historical Documents relating to Alphonse (Al) Capone, Chicago

Note: All Federal tax records are confidential by law. The availability of historical records is highly unusual. However, the records of the criminal investigation of Al Capone below are of historical significance and of interest to the public. Therefore, they are being made available under the Freedom of Information Act (FOIA). The IRS is committed to its FOIA obligations and to an open government by making information available as authorized by law. No other IRS records meet the unique set of circumstances that make the Capone records publicly available.

In 1931, the Internal Revenue Service’s Intelligence Unit completed an investigation of Alphonse Capone which led to his conviction for tax evasion for which he served 11 years in prison. A recent Freedom of Information Act Request for a copy of Special Agent Frank Wilson’s report to Elmer Irey about the Capone investigation led to a review of the records in light of the confidentiality provisions of Internal Revenue Code Section 6103. The review concluded that this information could be made available to the public – principally because Capone never filed a tax return.

The following are copies of reports and letters from the actual file which summarize the events and activities of the three year investigation of Al Capone.
