Criminal Tax Law

IRS Criminal Tax Investigations


The Internal Revenue Service takes criminal violations of the tax law seriously – so seriously that it has devoted a special unit to investigating potential criminal violations of the Internal Revenue Code, as well as ancillary financial crimes such as money laundering, currency infractions, antitrust matters and Bank Secrecy Act violations. This unit, the IRS Criminal Investigation Division (“CI”) is composed of Special Agents. These highly trained financial investigators employ such techniques as wiretaps, search warrants and undercover operations to detect and criminal conduct and apprehend suspects.. Special agents aggressively conduct exhaustive, in-depth investigations to uncover tax and financial crimes, including:

  • General Tax Fraud
  • Return Preparer Fraud
  • Questionable Refunds
  • Abusive use of Foreign & Domestic Trusts
  • Frivolous Filer/Non-Filer
  • Employment Tax Fraud
  • Excise Tax Fraud
  • Financial Institution Fraud
  • Insurance Fraud
  • Public Corruption
  • Offshore Bank Account Abuse
  • Narcotics-Related Issues
  • Organized Crime Issues

The IRS Criminal Investigation Division’s conviction rate is one of the highest in federal law enforcement. In addition to payment of back taxes owed, those convicted in court may face civil fines, penalties and even prison sentences.
