Imprisonment and Fines in Illinois

One of the biggest concerns our clients have is whether they will go to jail. We work to minimize the penalties you face, but it’s important to understand how criminal charges are handled in Illinois:

  • Misdemeanors: These are less serious offenses punishable by up to one year in county jail and fines.
  • Felonies: These are more serious crimes with sentences of more than a year in state prison and significant fines.

Federal charges, which are often investigated by agencies like the FBI or IRS, tend to have more severe penalties. Hanauer Law has a history of successfully securing reduced sentences and favorable outcomes for clients facing federal charges.
