Guide to Major Felonies | Illinois Charges & Penalties

What every Illinois resident facing a serious criminal charge needs to know — from the first 48 hours through sentencing and beyond.

Being charged with a felony is one of the most frightening experiences a person can go through. In a matter of hours, your job, your family, your freedom, and your future can all feel like they are on the line. If you are reading this, you or someone you love may be asking the same questions thousands of people ask online every day: Am I going to prison? Will I lose my job? Should I just take the first deal? Do I really need my own lawyer?

This guide answers those questions in plain English, with a focus on how felony cases work under Illinois law. It is not a substitute for advice about your specific case — but it will help you understand what you are facing and what to do next.

What Makes a Crime a Felony in Illinois?

In Illinois, a felony is generally any offense punishable by a year or more in state prison. Anything less serious is a misdemeanor. Illinois sorts felonies into classes, and the class of your charge is the single biggest factor in determining the potential penalty. Under the Unified Code of Corrections (730 ILCS 5/5-4.5), the classes are:

Two important caveats. First, these are ranges, not predictions — where you land depends on the facts, your history, and how well your case is presented. Second, specific statutes can make an offense non-probationable even if its class normally allows probation, and prior convictions can bump a sentence into the extended range or even require Class X sentencing. That is exactly why the charge on your paperwork is only the starting point. An attorney at CTM Legal Group can review the exact statute you are charged under and explain what your realistic exposure looks like — call (312) 818-6700.

The First 48 Hours: What to Do (and Not Do)

One of the most common regrets people share online is something they said or did in the first day or two after an arrest. Protect yourself:

• Stay silent and ask for a lawyer. You have the right to remain silent and the right to an attorney. Say clearly, “I am going to remain silent and I want a lawyer.” Then stop talking. Being polite and cooperative is fine; explaining your side of the story is not.
• Assume every jail call is recorded. Calls and video visits from jail are routinely recorded and can be used as evidence. Do not discuss the facts of your case with family or friends.
• Do not post about it. Stay off social media about the arrest, the alleged victim, or anything related. Prosecutors look.
• Do not contact witnesses or the alleged victim — even to apologize. Doing so can lead to new charges or detention, and may violate your release conditions.
• Be careful what you say to your employer. If the allegation involves your workplace (such as theft or embezzlement), statements to HR or loss prevention can become evidence. Talk to a lawyer before you sign or say anything.
• Write down what you remember — for your attorney’s eyes only — including names of witnesses and any cameras that may have recorded events.

If a loved one has just been arrested, the best thing you can do is get them legal help quickly. Call CTM Legal Group at (312) 818-6700 so an attorney can get involved before the first court appearance.

Will I Be Held in Jail Until Trial?

This is a question that has a different answer in Illinois than almost anywhere else in the country. Since September 18, 2023, the Pretrial Fairness Act (part of the SAFE-T Act) has eliminated cash bail statewide. Nobody in Illinois sits in jail simply because they can’t afford to pay a bond.

Many people charged with a felony are released with conditions, such as reporting to pretrial or social services; staying away from the complainant, witnesses, or certain addresses; and/or being placed on GPS or electronic monitoring. In many cases, prosecutors file a petition asking the judge to detain a defendant before trial. At that detention hearing, the State must prove by clear and convincing evidence that the person committed the offense and poses a real and present threat to someone’s safety or a risk of willful flight, and that no set of release conditions can address that risk.

Detention hearings happen fast, sometimes at the very first court appearance. Having an attorney prepared to challenge the State’s petition can be the difference between going home and waiting months in custody. If you or a family member is facing a detention hearing, call CTM Legal Group immediately at (312) 818-6700.

How a Felony Case Moves Through Court

Many people say the hardest part of a felony case is not knowing what comes next. While every case is different, most Illinois felony cases follow this general path:

1. Arrest and charging. Police make an arrest and the State’s Attorney approves felony charges.
2. First appearance. A judge informs you of the charges, addresses pretrial release or detention, and appoints a public defender if you request one and qualify.
3. Preliminary hearing or grand jury indictment. Before a felony can proceed, either a judge must find probable cause at a preliminary hearing or a grand jury must return an indictment. Under 725 ILCS 5/109-3.1, this must generally happen within 30 days if you are in custody, or 60 days if you are out.
4. Arraignment. You are formally presented with the charging document and enter a plea, usually “not guilty” at this stage.
5. Discovery and pretrial motions. Your attorney obtains the State’s evidence — police reports, body-camera video, lab results, witness statements — and may file motions to suppress illegally obtained evidence or dismiss charges.
6. Negotiation. Most cases are resolved through negotiation, which may result in reduced charges, a lower felony class, a misdemeanor, a diversion program, or dismissal.
7. Trial. If the case doesn’t resolve, you have the right to a trial before a judge or jury. The State must prove guilt beyond a reasonable doubt.
8. Sentencing. If there is a conviction, the judge considers aggravating and mitigating factors before imposing a sentence within the legal range.

Illinois also has a speedy trial statute (725 ILCS 5/103-5): a person in custody must generally be tried within 120 days, and a person out of custody within 160 days after making a written demand for trial. Delays caused by the defense pause the clock, so whether and when to demand trial is a strategic decision best made with counsel.

“Am I Going to Prison?” — Understanding Your Real Risk

This is the number-one question people ask on message boards, and the honest answer is: it depends. Prison is not automatic for many felonies in Illinois, especially for people without a prior record. Factors that often shape the outcome include:

• The class of the offense and whether it is probationable
• Your prior criminal history (or lack of one)
• Whether anyone was injured or a weapon was involved
• The strength of the State’s evidence and any constitutional problems with how it was gathered
• Mitigating factors such as employment, family responsibilities, treatment, and restitution

Possible outcomes short of prison can include probation, conditional discharge, periodic imprisonment, and — for eligible people — first-offender programs, drug treatment alternatives, or specialty courts (such as drug, mental health, or veterans courts). Some of these programs can end in dismissal of the charge if completed successfully, which can be life-changing.

These options are rarely offered automatically. Often, your attorney has to identify your eligibility and advocate for it. To find out which alternatives may be available in your case, call CTM Legal Group at (312) 818-6700.

Public Defender or Private Attorney?

Online, people often debate whether a public defender is “good enough.” Public defenders are licensed attorneys, many of them highly skilled and experienced in criminal court. The challenge is usually not ability — it is time. Public defenders frequently carry very heavy caseloads, which can limit how much individual attention each case receives.

A private attorney can often devote more time to investigating your case, communicating with you, consulting experts, and exploring every option before recommending a plea or trial. A private firm can also coordinate related issues that a felony charge often creates — such as immigration consequences, family law matters, or employment concerns.

Whichever route you choose, you deserve to understand your options. Call CTM Legal Group at (312) 818-6700 to talk through your case and how we can help.

Consequences That Go Beyond the Sentence

A felony conviction can follow you long after any sentence ends. These “collateral consequences” are often what worry people most, and they are a major reason not to accept a plea without understanding it fully:

• Employment: Many employers run background checks, and some industries restrict hiring people with certain convictions.
• Professional licenses: Nurses, teachers, real estate agents, commercial drivers, and other licensed professionals may face discipline or denial.
• Firearms: A felony conviction generally makes a person ineligible for an Illinois FOID card and prohibits firearm possession under federal law.
• Housing: Landlords and public housing authorities may consider criminal history.
• Immigration: For anyone who is not a U.S. citizen — including green card holders — certain convictions can lead to deportation, denial of naturalization, or a bar on returning to the U.S. Even a plea that seems minor can carry severe immigration consequences.
• Family law: A felony charge can affect parenting time, custody disputes, and orders of protection.

Can a Felony Be Cleared From My Record?

In Illinois, charges that end in dismissal or acquittal can generally be expunged. Convictions generally cannot be expunged, but many can be sealed, which hides them from most employers and the public. The general waiting period to seal a felony conviction is three years after the sentence is completed, and that wait can sometimes be shortened by earning a diploma, GED, degree, or vocational certificate while serving the sentence.

Illinois also enacted the Clean Slate Act (HB 1836), signed on January 16, 2026, which will make sealing automatic for many eligible non-violent records. The State is building the system in phases, with automatic sealing expected to begin in 2029. The Act does not expand which offenses qualify: serious violent felonies, sex offenses, domestic violence offenses, and DUI-related convictions generally remain ineligible.

The most effective way to protect your record, though, is to fight for the best possible outcome at the start of your case. A reduced charge or a qualifying program can make future sealing — or full expungement — possible. CTM Legal Group can help with both your pending case and record relief afterward. Call (312) 818-6700.

Common Mistakes People Make After a Felony Charge

• Waiting to get a lawyer until the case “gets serious.” A felony is already serious, and early decisions shape everything.
• Talking to police to “clear things up.” Statements are rarely helpful to the person making them.
• Taking the first plea offer without understanding it, including its immigration, licensing, and record consequences.
• Missing court dates or violating release conditions, which can lead to a warrant, detention, or new charges.
• Relying on internet advice about someone else’s case in another state. Laws, judges, and prosecutors differ, and so do outcomes.
