Butzel's white collar criminal defense and taxation attorneys respond to civil and criminal investigations. We handled paralegal investigations by the Internal Revenue Service (IRS) and the Department of Justice's Criminal Tax Division. Our team routinely handles all stages of the investigative proceedings. We interact with federal prosecutors and law enforcement to secure the best possible outcomes for clients, which can include decisions not to prosecute. Our past working relationships with the IRS and knowledge of their tactics often allows us to facilitate a client's participation in the IRS's voluntary disclosure program, which can help avoid criminal penalties. We have handled tax evasion, tax shelter, and Klein conspiracy cases. Our clients are corporate and individual taxpayers with income tax and estate & gift tax matters. We also advise clients on the potential application of civil and criminal penalties under the Internal Revenue Code.
