Aggravated assault in Illinois can be charged as either a misdemeanor or a felony, depending on the circumstances. Under 720 ILCS 5/12-2, the offense ranges from a Class A misdemeanor carrying up to one year in county jail to a Class 3 felony punishable by two to five years in prison. Where the assault happened, who was targeted, and whether a weapon or vehicle was involved all decide which classification applies.1Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/12-2 – Aggravated Assault
What Illinois Counts as Aggravated Assault
The starting point is simple assault. Under 720 ILCS 5/12-1, a person commits assault by knowingly engaging in conduct that makes someone else reasonably fear they are about to be hit or harmed. No physical contact is required. Raising a fist and lunging can be enough. On its own, that is a Class C misdemeanor.2Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/12-1 – Assault
An assault becomes aggravated when one of three aggravating factors is present. A single incident can trigger more than one, and that combination affects how the charge is classified.
Location
An assault committed against someone on or near a public way, public property, a place of public accommodation, a sports venue, or a house of worship is aggravated assault. Location alone puts the charge at the Class A misdemeanor level.1Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/12-2 – Aggravated Assault
Who Was Targeted
Assaulting people in certain roles elevates the charge, but only if the defendant knew or had reason to know the victim’s status. Protected categories include peace officers, firefighters, emergency medical personnel, correctional officers, and emergency management workers acting in their official duties; teachers and school employees on or near school grounds and park district employees on or near park property; transit employees and passengers; community policing volunteers; private security officers; utility workers; and individuals 60 or older or with physical disabilities.
Most victim-status offenses are Class A misdemeanors, but several are automatic Class 4 felonies. Assaults on peace officers, firefighters, emergency personnel, transit employees, and certain other protected workers are felonies regardless of whether a weapon is involved. Assaults on the elderly or on people with disabilities become Class 4 felonies when a categorized weapon is used.
Weapons, Firearms, and Vehicles
The third category is how the assault was carried out, and the penalty range here is wide.
- Class A misdemeanor: using a deadly weapon other than by discharging a firearm, wearing a hood or mask to conceal identity, or recording the assault with intent to distribute the recording.
- Class 4 felony: discharging a firearm (not from a vehicle), aiming a laser sight attached to a firearm at someone, or using a firearm against a peace officer or other protected worker.
- Class 3 felony: discharging a firearm from a motor vehicle, or operating a motor vehicle to threaten a protected worker listed in the statute.
The weapon categories referenced in the statute come from 720 ILCS 5/33A-1 and cover handguns, rifles, shotguns, stun guns, knives with blades at least three inches long, bludgeons, and similar items.3Illinois General Assembly.

Penalties by Classification
Class A Misdemeanor
Most aggravated assault charges land here. The maximum is one year in county jail and a fine of up to $2,500. Location-based offenses, deadly-weapon cases that don’t involve firing a gun, and many victim-status offenses sit at this level.4Illinois General Assembly. Illinois Compiled Statutes 730 ILCS 5/5-4.5-55 – Class A Misdemeanors; Sentence
Class 4 Felony
A Class 4 felony carries one to three years in prison and a fine of up to $25,000. Extended-term sentencing can push the range to three to six years. Probation is available, with a maximum probation term of 30 months.5Illinois General Assembly. Illinois Compiled Statutes 730 ILCS 5/5-4.5-45 – Class 4 Felonies; Sentence
Class 3 Felony
The most serious aggravated assault classification carries two to five years in prison and a fine of up to $25,000. Extended-term sentencing can increase the prison range to five to ten years.6Illinois General Assembly. Illinois Compiled Statutes 730 ILCS 5/5-4.5-40 – Class 3 Felonies; Sentence Felony fines in Illinois generally cap at $25,000 per offense unless a statute says otherwise.7Illinois General Assembly.

Defenses That Can Change the Outcome
Self-Defense
Under 720 ILCS 5/7-1, you can use force against another person when you reasonably believe it is necessary to protect yourself or someone else from an imminent unlawful attack. The key word is “reasonably.” You don’t have to be right about the threat, but your belief has to have been genuine and reasonable. Deadly force is justified only when you reasonably believe it is necessary to prevent death, great bodily harm, or a forcible felony.8Illinois General Assembly. Illinois Compiled Statutes 720 ILCS 5/7-1 – Use of Force in Defense of Person
Self-defense in aggravated assault cases turns on whether the perceived threat was serious enough to justify the response and whether the level of force matched the danger. Pulling a knife during a verbal argument is a much harder claim than brandishing a weapon in response to seeing an attacker reach for a gun.
Lack of Intent
Assault requires that the defendant knowingly engaged in threatening conduct. Accidents don’t count. If someone swings a bat during a baseball game and the follow-through nearly hits a bystander, that is not the same as deliberately swinging at a person.
Lack of Knowledge of Victim Status
For victim-status charges, the prosecution has to prove the defendant knew the victim belonged to a protected category. If you did not know the person you threatened was an off-duty officer or a transit worker, the aggravated version of the charge may not hold, even if a simple assault charge could.
Mitigation at Sentencing
Even when a defense doesn’t win an acquittal, mitigating factors can lower the sentence. Judges weigh a clean record, provocation by the victim, mental health issues, and cooperation with the court. On a felony, those factors can be the difference between prison and probation.
Consequences That Follow a Conviction
Firearm Rights
A felony aggravated assault conviction ends firearm possession under both state and federal law. Federal law prohibits anyone convicted of a crime punishable by more than one year of imprisonment from possessing firearms or ammunition.9Office of the Law Revision Counsel. United States Code Title 18 Section 922 – Unlawful Acts In Illinois, a felony conviction results in revocation of your Firearm Owner’s Identification (FOID) card, and you cannot obtain a new one without having your firearm rights restored through administrative or judicial proceedings.10Illinois State Police. FOID Card Review Board – Felony The federal ban runs independently, so state-level restoration doesn’t automatically clear it.
Immigration
Non-citizens face additional exposure. A conviction for a crime involving moral turpitude, committed within five years of admission and carrying a possible sentence of one year or more, is a ground for deportation. Two such convictions at any time after admission can also trigger removal.11Office of the Law Revision Counsel. United States Code Title 8 Section 1227 – Deportable Aliens Whether a specific aggravated assault charge qualifies depends on the subsection and the facts. For non-citizens, a plea to a charge that carries a possible one-year sentence can produce immigration consequences worse than the criminal penalty itself.
Employment and Professional Licensing
A felony conviction shows up on background checks and can disqualify you from licensed work in healthcare, education, law enforcement, and financial services. A misdemeanor aggravated assault can still raise concerns for employers in fields involving vulnerable populations.
Voting
People serving a sentence of confinement cannot vote in Illinois. Voting rights are restored automatically on release, and no petition is required. You re-register once you are out.
Travel
An aggravated assault conviction can affect eligibility for federal trusted traveler programs. The Transportation Security Administration lists “assault with intent to kill” as an interim disqualifying offense for programs like TSA PreCheck and reserves discretion to deny applicants with other serious convictions or any period of incarceration over 365 consecutive days.12Transportation Security Administration. Disqualifying Offenses and Other Factors
Sealing an Aggravated Assault Record
Illinois does not allow expungement of most criminal convictions. Expungement is reserved for cases that were reversed, vacated, or resolved by a gubernatorial pardon. Many aggravated assault convictions can be sealed, which hides the record from most public background checks while keeping it accessible to law enforcement.
The waiting period to seal a misdemeanor or felony conviction is three years from the end of your last sentence, including any supervision, probation, or parole. Sealing does not erase the record, and certain employers in sensitive industries can still see it, but it removes the conviction from standard background check databases.
Why Plea Bargains Drive Most Cases
Most aggravated assault cases in Illinois don’t go to trial. A common negotiation involves pleading guilty to a lesser charge, such as reducing a Class 4 felony to a Class A misdemeanor, in exchange for a lighter sentence or probation instead of prison.
The felony-misdemeanor line matters for more than the sentence. Pleading down to a misdemeanor avoids felony-level collateral consequences: no loss of firearm rights, no felony on background checks, and reduced immigration risk for non-citizens. Any plea, though, means admitting guilt and creating a criminal record that can be used in future proceedings.
Prosecutors are more open to negotiation when the evidence has weaknesses: a shaky witness identification, unclear video, or a real question about whether the defendant knew the victim’s protected status. Identifying those pressure points early tends to produce better offers. The decision to accept or reject a plea belongs to the defendant, and it should never be made without understanding both the criminal penalty and the collateral consequences of the specific charge on the table.
