Class 3 Felony in Illinois: Sentencing, Offenses, and Record Sealing

A Class 3 felony in Illinois is punishable by two to five years in prison, a fine of up to $25,000, and a one-year term of mandatory supervised release after any prison time ends.¹ It sits in the middle of the state’s felony hierarchy, below Class X, 1, and 2, and above Class 4. Probation of up to 30 months is available in place of prison for many defendants, and the real-world sentence often depends as much on prior record and the specific facts as on the statutory label.

The Prison Range and When It Doubles

The baseline is two to five years. Where a defendant lands in that window depends on the facts of the offense, criminal history, and whether aggravating or mitigating factors are present. A first-time offender with no violence in the record tends toward the low end; someone with prior convictions or a more serious set of facts moves up.

Extended-term sentencing changes the picture. When a defendant qualifies, the range becomes five to ten years.¹ Extended terms are available under 730 ILCS 5/5-8-2 when a defendant has qualifying prior felony convictions, when the offense was exceptionally brutal, when the victim was particularly vulnerable, or when other statutory aggravators apply. Prior history matters most here. A person with the right record facing a Class 3 can realistically be sentenced to a decade.

How Much Time You Actually Serve

A nominal sentence rarely matches time behind bars. Most Class 3 felonies qualify for day-for-day sentence credit: one day off for each day served with good conduct. In practice, that cuts the sentence roughly in half for a well-behaved inmate. The Truth-in-Sentencing law requires some offenses to be served at 85% or 100%, but most Class 3 felonies fall outside that list.¹

Release doesn’t end the sentence. A one-year mandatory supervised release term begins automatically when the prison portion ends.¹ MSR is the current form of post-prison supervision in Illinois, and the Illinois Prisoner Review Board sets its conditions, which can include drug testing, employment requirements, and residence restrictions.² A violation can send you back to prison.

Probation, Fines, and Restitution

Not every Class 3 conviction leads to prison. Probation is a sentencing option, and its term cannot exceed 30 months.¹ Common conditions include community service, drug or mental health treatment, regular reporting to a probation officer, weapon prohibitions, and no-contact orders. Violating any condition can trigger revocation and a prison sentence. Conditional discharge works similarly, with lighter supervision but the same 30-month cap.

The fine can reach $25,000 and can be imposed with or without prison.¹ Separate from any fine, a court can order restitution, which compensates the victim directly for documented losses like medical bills or property damage. The amount is based on actual losses and the defendant’s ability to pay.

What Counts as a Class 3 Felony

Several familiar offenses sit at this level, and the exact charge depends on specific facts within each statute.

Theft

Theft of property worth more than $500 but not more than $10,000 is a Class 3 felony. Theft directly from a person’s body, such as pickpocketing or purse-snatching, is a Class 3 even when the value is $500 or less. That distinction matters: taking a $200 phone off a store shelf is a misdemeanor, but lifting the same phone from someone’s pocket is a felony because of the contact with the victim. The charge can rise to Class 2 if the theft occurred at a school or place of worship or involved government property.³

Aggravated Battery

Aggravated battery is a Class 3 felony by default, unless the statute specifies a different class for the particular variant. It covers battery committed under circumstances that elevate it above simple battery, such as in a public place, against a public employee, or against a person over 60. More serious versions involving firearms, great bodily harm, or especially vulnerable victims can be charged as Class 2, Class 1, or Class X.⁴

Drug Offenses

Some controlled substance offenses, including certain possession and possession-with-intent-to-deliver charges, are Class 3 felonies. The class depends on the substance and the quantity, with separate statutes for cannabis, controlled substances, and methamphetamine. Small changes in weight can shift a charge up or down a class, so the specific statute and quantity threshold matter more than the general category.

Collateral Consequences

The sentence is only part of the exposure. A Class 3 conviction brings restrictions that outlast prison, probation, and MSR.

Firearm Rights

Federal law bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.⁵ Every Class 3 felony qualifies. In Illinois, your FOID card will be revoked. Restoration is possible through the FOID Card Review Board, but it requires extensive documentation and is not guaranteed.⁶

Employment

The Illinois Human Rights Act makes it a civil rights violation for an employer to refuse to hire someone because of a conviction record unless there is a substantial relationship between the offense and the job, or the hire would pose an unreasonable risk to property or public safety.⁷ A theft conviction can keep you out of banking work, but it can’t be used to block a warehouse job with no access to funds. Licensed professions, including healthcare, education, and law enforcement, often remain out of reach after a felony.

Housing

Public housing authorities running Section 8 and other federal programs can run background checks and deny admission based on criminal history. Lifetime sex offender registrants are barred automatically; other felony convictions fall within the authority’s discretion. Applicants must be notified of a disqualifying record and given a chance to dispute it before a denial is final.⁸ Private landlords set their own rules, and many screen for felonies.

Immigration

Non-citizens face some of the heaviest consequences. Federal law makes a person deportable for a conviction of a crime involving moral turpitude committed within five years of admission when the offense carries a potential sentence of one year or more.⁹ Two convictions for crimes involving moral turpitude at any time after admission, even arising from a single trial, also trigger deportability. Class 3 sentences exceed the one-year threshold, and many of the underlying offenses qualify. Removal proceedings, denial of naturalization, and bars to reentry are all on the table. A non-citizen should talk to an immigration attorney before accepting any plea.

International Travel

Canada treats people with criminal records as potentially inadmissible. Entry can be possible through individual rehabilitation or deemed rehabilitation, but at least five years must have passed since the end of the sentence, including any probation.¹⁰ A temporary resident permit can cover travel needed before that waiting period runs.

Defending the Charge

Two defense angles come up often in Class 3 cases. The first is suppression. The Fourth Amendment bars unreasonable searches and seizures, and evidence obtained through an illegal stop, a warrantless home search, or an improperly executed warrant can be excluded.¹¹ Without that evidence, the prosecution may not be able to proceed.

The second is intent. Most Class 3 felonies require proof the defendant acted knowingly or intentionally. Theft requires intent to permanently deprive the owner. Drug charges typically require knowledge of the substance’s presence and nature. Evidence that undercuts that element, whether through the defendant’s statements, the arrest circumstances, or the relationship between the defendant and the property, can defeat the charge.

Sealing a Class 3 Felony Record

Illinois allows some Class 3 convictions to be sealed through a Certificate of Sealing from the Prisoner Review Board. The applicant must have a single Class 3 or Class 4 felony conviction and must wait at least five years from the end of the sentence or from the last arrest, whichever is later.¹² Sealing hides the record from most background checks, though law enforcement and certain state agencies can still see it.

Many Class 3 offenses are excluded. Sex offenses, crimes of violence, domestic violence offenses, gun offenses, and DUI convictions cannot be sealed. Theft, deceptive practices, forgery, possession of burglary tools, and drug possession are specifically listed as eligible. Drug cases also require proof that a drug treatment program was completed, submitted with the petition.¹² Sealing is not automatic; the petition goes through review and can be denied.
