What Is a Class A Misdemeanor in Illinois?
Illinois law divides criminal offenses into felonies and misdemeanors. Within misdemeanors, there are three classes: A, B, and C. Class A is the most serious. It sits just below the felony threshold, and it is where the overwhelming majority of misdemeanor prosecutions in Illinois.
If you have been charged with a Class A misdemeanor, it’s crucial to understand what that means so you can be most prepared and secure the best defense. You are facing the possibility of spending nearly a full year in county jail. You are facing fines, court costs, and mandatory assessments. And if convicted, you are facing a criminal record that follows you into job applications, professional licensing reviews, and housing screenings.
The penalties for a Class A misdemeanor are governed by 730 ILCS 5/5-4.5-55. Calling this a minor charge simply because it’s classified as a misdemeanor, rather than a felony, is a mistake prosecutors are counting on you to make.
Class A Misdemeanor Penalties
A conviction for a Class A misdemeanor in Illinois can result in:
- Up to 364 days in county jail (Illinois statute uses 364 days specifically, not “one year”)
- Fines of up to $2,500, plus mandatory court costs and assessments
- Probation of up to 24 months
- Conditional discharge
- Court supervision of up to 24 months
That last option, court supervision, is worth understanding before anything else.
Supervision vs. Conviction
Court supervision is not a conviction. If the court grants supervision and you complete all conditions, including payment of fines, no additional offenses, and any required programming, the charge does not become a conviction on your permanent record. For eligible charges, pursuing supervision is often a better outcome than what is achievable at trial. An experienced attorney knows how to argue for it.
Common Class A Misdemeanor Charges in Illinois
Class A is not a catch-all for minor wrongdoing. It covers some of the most consequential charges Illinois prosecutors bring. Each of the charges below is a Class A misdemeanor under standard circumstances, and each carries its own elevation triggers that can push it into felony territory.
1
DUI (1st & 2nd Offense)
Jail, license suspension, mandatory assessments. Elevates to felony on 3rd offense or with aggravating factors.
A first DUI offense under 625 ILCS 5/11-501 is a Class A misdemeanor. Beyond the criminal penalties, up to 364 days in jail and a $2,500 fine, a conviction triggers administrative consequences through the Secretary of State: statutory summary suspension of driving privileges, mandatory alcohol evaluation, and potential installation of a Breath Alcohol Ignition Interlock Device.
A second DUI is also a Class A misdemeanor, but with mandatory minimums. A conviction requires either a minimum of five days in jail or 240 hours of community service. There is no discretion around that floor.
The elevation trigger matters here. A third DUI conviction in Illinois is a Class 2 felony. Any DUI that involves a child under age 16 in the vehicle, great bodily harm, or a fatality can escalate to aggravated DUI on the first offense.
2
Domestic Battery
Physical contact with a household or family member. Prior conviction elevates to Class 4 felony. Permanently ineligible for expungement.
Under 720 ILCS 5/12-3.2, a person commits domestic battery when they knowingly cause bodily harm to, or make insulting or provoking physical contact with, a family or household member. That includes spouses, former spouses, parents, children, and individuals in a dating relationship.
A first offense is a Class A misdemeanor. With a prior domestic battery conviction, the charge elevates to a Class 4 felony. Strangulation, great bodily harm, or use of a firearm in the commission of the offense elevates it to aggravated domestic battery, a Class 2 felony.
The record consequence here is permanent: a domestic battery conviction in Illinois is not eligible for expungement or sealing under 20 ILCS 2630/5.2, regardless of how much time has passed. That makes fighting the charge, not just managing the sentence, the only path to protecting your record.
3
Battery
Causing bodily harm or insulting/provoking contact. Elevates to Class 3 felony as aggravated battery.
Battery under 720 ILCS 5/12-3 involves knowingly causing bodily harm to another person or making physical contact of an insulting or provoking nature. It is a Class A misdemeanor at its base level.
The line between battery and aggravated battery is crossed when certain factors are present: the victim is a teacher, police officer, or other protected class of person; the offense occurs on school grounds; the offender uses a deadly weapon; or great bodily harm results. Aggravated battery is a Class 3 felony.
4
Resisting/Obstructing a Peace Officer
Knowingly interfering with an officer’s duties. Elevates to Class 4 felony if the officer sustains injury.
Under 720 ILCS 5/31-1, a person commits this offense when they knowingly resist or obstruct the performance of an authorized act by a peace officer. This is broadly applied. It can mean physical resistance during an arrest, providing false information, or simply failing to comply with a lawful directive in a way the officer interprets as deliberate interference.
The charge elevates to a Class 4 felony if the officer sustains bodily harm as a direct result of the resistance. Because the charge frequently turns on the officer’s account of what happened and the defendant’s state of mind, body-worn camera footage, dispatch records, and independent witness testimony are often the most important evidence in these cases.
5
Retail Theft
Merchandise value of $300 or less. Elevates to Class 4 felony above $1,000 or with a prior conviction.
Retail theft under 720 ILCS 5/16-25 is a Class A misdemeanor when the value of the merchandise involved does not exceed $300. The prosecution does not need to prove you left the store. Concealment, price switching, under-ringing, and use of a theft detection shielding device all qualify.
Elevation is swift: once the value exceeds $1,000, retail theft becomes a Class 4 felony. A prior retail theft conviction also triggers felony-level prosecution on a subsequent offense, regardless of the merchandise value.
6
Unlawful Use of a Weapon
Carrying certain weapons or a legal firearm improperly. Conviction can affect future firearm rights.
Illinois prohibits both carrying certain weapons outright and carrying a legal firearm in a manner that violates state law. Under 720 ILCS 5/24-1 and 720 ILCS 5/24-3.1, common Class A scenarios include carrying an uncased, loaded firearm in a vehicle, possessing a firearm without a valid FOID card, or carrying a prohibited weapon such as a bludgeon or metallic knuckles.
A conviction carries consequences beyond the sentence. Certain UUW convictions affect your ability to own or possess firearms going forward. If you hold a professional license or work in a field requiring a security clearance, the impact can extend further. The legality of the initial stop and any subsequent search is often the central issue in these cases.
7
Drug Paraphernalia Possession
Possession without intent to deliver. Elevates to felony with intent.
Under the Illinois Drug Paraphernalia Control Act (720 ILCS 600/3.5), possession of paraphernalia, items used to ingest, prepare, package, or store controlled substances, without intent to deliver is a Class A misdemeanor. The charge often accompanies other drug charges, which means the entire case needs to be evaluated together.
8
Driving on Suspended/Revoked License
Class A when not DUI-related. Elevates to Class 4 felony when the suspension stems from a DUI conviction.
Under 625 ILCS 5/6-303, driving on a suspended or revoked license is a Class A misdemeanor when the underlying reason for the suspension is unrelated to a DUI. That changes when the license was suspended or revoked specifically because of a DUI conviction. In that circumstance, the charge elevates to a Class 4 felony, carrying potential prison time instead of county jail.

When a Class A Misdemeanor Becomes a Felony
Most Class A misdemeanor charges are threshold offenses. The factors that push them over the line into felony territory are worth understanding before your case moves forward, because they affect not just sentencing but the entire shape of your defense.
Common elevation triggers across Class A charges include: a prior conviction for the same or a related offense; the severity of harm caused to the victim; the victim’s status as a peace officer, teacher, child, or other protected class; the location of the offense on school property or at a place of worship; or use of a weapon during the commission of the offense.
Prior Convictions Change Everything
A second domestic battery conviction is a Class 4 felony. A third DUI is a Class 2 felony. If you have a prior record, your current Class A charge may already be sitting at the felony threshold. The time to address this is before the prosecution locks in a charging decision, not after.
The charging document filed by the prosecution is not necessarily final. Whether the alleged aggravating factors actually exist, whether the prior conviction is valid and properly applied, and whether the facts support the elevated charge are all questions a defense attorney should be raising from the moment of arrest.
How Class A Misdemeanor Cases Are Prosecuted in Illinois
Understanding how these cases are built helps you understand where they can be challenged.
After an arrest, the prosecution typically has 18 months from the date of the alleged offense to file misdemeanor charges under Illinois law. Most Class A cases move through initial appearance, bond hearing, arraignment, and into the pretrial discovery phase relatively quickly.
During discovery, the prosecution is required to disclose the evidence it intends to use: police reports, body-worn camera footage, witness statements, lab results for drug-related charges, and any recorded statements made by the defendant. That disclosure is the starting point for building a defense.
What prosecution looks for in a Class A case are credible, consistent police accounts; physical evidence that supports the officer’s narrative; and an absence of exculpatory evidence. What that means for the defense is that inconsistencies between the police report and the body camera, gaps in the evidence chain, and witnesses whose accounts differ from the officer’s all become leverage points.
Pat Weiland spent nearly a decade as a DuPage County Assistant State’s Attorney before joining Dolci Weiland & Sendlak. He prosecuted DUI cases, battery cases, and felony charges in the same courthouse system where many of these misdemeanor cases are heard today. That perspective shapes how we evaluate the state’s case, how we approach pretrial motions, and how we negotiate when negotiation is the right call.
Defending Class A Misdemeanor Charges
There is no single defense that fits every Class A charge. Strategy depends on the specific offense, the facts of the arrest, the strength of the evidence, and the client’s criminal history and personal priorities. What does not change is the starting point: every piece of evidence gets examined, every procedure gets scrutinized, and every available outcome gets evaluated against what actually serves the client.
Challenge the Evidence
Every Class A prosecution depends on evidence, and evidence can be challenged. Was the stop lawful? Was the search authorized? Does the body camera footage match the officer’s report? Are the witnesses credible and consistent? A charge that looks solid in the police report often looks different after full discovery.
Pursue the Best Outcome
Not every case goes to trial, and a trial is not always the best path to the best result. For eligible charges, supervision avoids a conviction on the record entirely. Charge reduction, conditional discharge, and dismissal on evidentiary grounds are all outcomes worth pursuing. Knowing which to target requires knowing how the prosecution builds its case.
Common Defense Strategies
Unlawful stop or search. The Fourth Amendment prohibits unreasonable searches and seizures. If the initial stop lacked legal justification, or if evidence was obtained through a warrantless search without a valid exception, a motion to suppress can remove that evidence from the case. For charges that depend entirely on what was found during the search, suppression can end the prosecution.
Lack of knowing or intentional conduct. Many Class A offenses require proof that the defendant acted knowingly or intentionally. Battery requires knowing contact. Resisting arrest requires knowing resistance. Where the facts support a defense of accident, mistake, or lack of awareness, challenging the mental state element is a legitimate path.
Challenging the complaining witness. In domestic battery and battery cases, the complaining witness’s account is often the core of the prosecution’s case. Prior inconsistent statements, motive to fabricate, and credibility problems are grounds for cross-examination that can undermine the prosecution’s narrative at trial.
Negotiating for supervision. For first-time or low-criminal-history defendants facing eligible Class A charges, court supervision is a meaningful outcome. It requires completing the court’s conditions but if completed successfully, the charge does not become a conviction. For someone whose livelihood depends on a clean record, that distinction matters significantly.
Class A Misdemeanor Convictions and Your Record
Expungement and Sealing Eligibility
Whether a Class A conviction can be cleared from your record depends on the specific charge.
For cases resolved through court supervision: if you complete all conditions successfully, the charge is not a conviction, and you may petition for expungement under 20 ILCS 2630/5.2 after the applicable waiting period.
For cases resulting in a conviction: most Class A misdemeanor convictions become eligible for expungement after a two-year waiting period following the completion of the sentence.
The exception list is significant. The following Class A convictions are permanently ineligible for expungement or sealing under Illinois law, regardless of how much time passes: DUI convictions, domestic battery convictions, and sex-related convictions. For those charges, a conviction stays on your record permanently. That is not a reason to accept a plea. It is the precise reason fighting the charge aggressively from the start is the only path that protects your future.
Collateral Consequences Beyond the Courtroom
A Class A conviction’s impact extends well past the sentence itself.
Employment. Criminal background checks are routine for employers across nearly every industry. A Class A conviction, especially for domestic battery, DUI, or a weapons charge, can eliminate candidates from consideration before an interview takes place.
Professional licensing. Illinois licensing boards for healthcare, law, education, real estate, and other regulated professions routinely review applicants’ and licensees’ criminal histories. A Class A conviction can trigger a licensing investigation, suspension, or denial.
Housing. Landlords and property management companies commonly screen applicants’ criminal records. A conviction limits your options and can result in denial of housing applications.
Second Amendment rights. Certain UUW and weapons-related Class A convictions carry consequences for future firearm ownership and possession rights under both Illinois and federal law.
Immigration. Non-citizens facing Class A charges should be aware that certain convictions can trigger immigration consequences including deportation proceedings or a finding of inadmissibility. Criminal defense counsel and immigration counsel should coordinate from the outset.

Frequently Asked Questions
Most Class A convictions become eligible for expungement two years after the sentence is complete. The major exceptions are DUI convictions, domestic battery convictions, and sex-related offenses, which are permanently ineligible regardless of time elapsed. Cases resolved through court supervision, rather than conviction, can also be expunged after the applicable waiting period and successful completion of all conditions.
Court supervision is a sentence, not a conviction. If the court places you on supervision and you complete all conditions without a new offense, the charge does not become a conviction on your permanent criminal record. This distinction matters for background checks, licensing, and future expungement eligibility. Not all Class A charges are eligible for supervision, and eligibility depends on your criminal history and the specific charge.
Yes. Charge reduction is a common outcome in misdemeanor defense. A Class A charge can be reduced to a Class B or Class C misdemeanor, or resolved through supervision rather than conviction, depending on the facts of the case, the strength of the evidence, and the client’s criminal history. Early intervention by a defense attorney gives the best opportunity to influence the outcome.
Yes. The prosecution is represented by a trained attorney whose job is to secure a conviction. The penalties for a Class A misdemeanor include nearly a year of jail time, thousands of dollars in fines, and a permanent record that affects employment, housing, and professional licensing. The complexity of the law, the value of early intervention, and the long-term consequences of a conviction all make legal representation essential, not optional.
Under Illinois law, the prosecution generally has 18 months from the date of the alleged offense to file misdemeanor charges. After that window closes, the charges are time-barred. If you were arrested but no charges have been filed, this timeline is relevant to your case and worth discussing with an attorney.
