Federal Sentencing Hearings

If you have been charged with a white-collar crime, and whether you have decided to enter a guilty plea or proceed to trial, your lawyer must be familiar with the federal sentencing guidelines and must be prepared to argue for the lowest possible sentence.

Federal sentencing is a complex area of law and planning for federal sentencing includes many moving parts, such as: 

  • The sentencing range for the crime you are charged with, including any mandatory minimum sentences
  • Calculation of your criminal history category and base offense level
  • Particularly important in white-collar cases is the total “loss amount” and how it will affect the offense level
  • Reductions in the offense level for things like acceptance of responsibility or downward departures based on substantial assistance
  • When to object to the presentence investigation report
  • Civil forfeitures and restitution.
