Caroline Rule Representative Matters

  • Persuaded the United States Attorney's Office for the District of New Jersey to charge a doctor with one count of making a false statement to the IRS, when he had in fact evaded $4.2 million in taxes over a period of years; and then persuaded the Court to sentence the doctor to probation and community service, when the advisory sentence under the United States Sentencing Guidelines was 36 months in jail.

  • Represented the former head of KPMG’s tax practice in what was then termed the largest tax fraud prosecution in United States history, and obtained dismissal of the entire indictment on grounds of prosecutorial misconduct.
  • Persuaded the Criminal Investigation function of the IRS that a client who failed to collect and pay over employment taxes for many years did not act willfully, and that the matter should be transferred back to the IRS Civil Division.

  • In connection with a very large and complicated estate, persuaded the IRS that, by placing stock certificates with bearer stock powers into a safety deposit box to which the executor had access, the decedent had made a completed gift to the executor, which saved the estate millions in estate taxes.
  • Negotiated a misdemeanor plea and non-jail sentence for the owner of a medical laboratory who characterized kick-backs to doctors as ordinary business expenses.
