Class 3 Felony in Illinois: Sentences, Defenses, and Consequences

A Class 3 felony in Illinois is punishable by two to five years in prison, a fine of up to $25,000, and up to 30 months of probation when the court chooses that alternative. It sits in the middle of Illinois’ felony ladder: more serious than a Class 4, less serious than Class 2, Class 1, and Class X. The offenses that fall here include theft in certain dollar ranges, most aggravated battery, and some drug crimes. The consequences reach past the sentence itself and into firearm rights, jobs, housing, and, for non-citizens, immigration status.

The Prison Range and When It Doubles

The standard sentence is two to five years.¹ Where a defendant lands inside that window depends on their record, the harm caused, and any aggravating or mitigating facts the court weighs at sentencing.

An extended term pushes the range to five to ten years.¹ Extended terms become available when the defendant has prior felony convictions, when the conduct was particularly brutal, when a vulnerable victim was involved, or when other aggravating factors under 730 ILCS 5/5-8-2 apply. A repeat offender charged with a Class 3 can realistically be looking at a decade rather than the five years many assume is the ceiling.

How Much Time You Actually Serve

Most Class 3 felonies qualify for day-for-day sentence credit. One day of good conduct credit for each day served means a person who stays out of trouble in prison generally serves about half the sentence imposed. Offenses on the Truth-in-Sentencing list require 85% or 100% of the sentence, but most Class 3 offenses aren’t on that list.¹

Release from prison is not the end of the sentence. A one-year mandatory supervised release term follows automatically.¹ MSR replaced traditional parole in Illinois. It’s supervision, not discretionary early release, and the Illinois Prisoner Review Board sets the conditions, which can include drug testing, employment requirements, and residence restrictions.² A violation can send you back inside.

Probation, Fines, and Restitution

Not every Class 3 conviction ends in prison. Probation is available, capped at 30 months.¹ Common conditions include community service, drug treatment, regular check-ins with a probation officer, and prohibitions on possessing weapons or contacting specific people. Violating any condition can trigger revocation and a prison sentence. Conditional discharge works similarly but with lighter supervision, under the same 30-month cap.

The court can impose a fine up to $25,000, either alongside prison or on its own.¹ Restitution is separate: it goes to the victim to cover actual documented losses such as medical bills and property damage, and the amount depends on those losses and the defendant’s ability to pay.

Which Offenses Are Class 3 Felonies

Theft

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

Aggravated Battery

Aggravated battery is a Class 3 by default unless the statute specifies otherwise. It covers physical harm committed under aggravating circumstances, such as in a public place, against a public employee, or against someone over 60. More serious versions of the offense can be Class 2, Class 1, or Class X depending on factors like use of a firearm or great bodily harm.⁴

Drug Offenses

Certain drug crimes are Class 3 felonies, including some forms of possession with intent to deliver and possession of controlled substances in specific quantities. Classification turns on the substance and the amount. Illinois has separate statutes for cannabis, controlled substances, and methamphetamine, each with its own thresholds. A small difference in weight can move a charge from Class 4 to Class 3, or from Class 3 to something more serious, so the exact quantity and the exact statute both matter.

Defenses Worth Raising

Suppressing the Evidence

If police obtained the evidence through an illegal stop, a warrantless search that didn’t fit an exception, or an improperly executed warrant, the Fourth Amendment allows that evidence to be suppressed.⁵ Without the suppressed evidence, the prosecution may not be able to move forward. This defense turns on a careful review of every step in the investigation, from the initial encounter through the chain of custody.

Lack of Intent

Many Class 3 offenses require proof the defendant acted knowingly or intentionally. Theft requires intent to permanently deprive the owner of property. Drug possession requires that you knew the substance was present and knew what it was. If you genuinely didn’t know a controlled substance was in your car, or believed the property you took belonged to you, the intent element can fail. Attorneys build the argument from the defendant’s statements, the circumstances of the arrest, and the defendant’s relationship to the property or substance.

Consequences That Follow the Sentence

Firearm Rights

Federal law bars anyone convicted of a crime punishable by more than one year in prison from possessing firearms or ammunition.⁶ Because every Class 3 felony carries a potential sentence of two to five years, every Class 3 conviction triggers this ban. Illinois will revoke your FOID card. Restoration is possible through the FOID Card Review Board, but the process demands extensive documentation and isn’t guaranteed.⁷

Employment

The Illinois Human Rights Act makes it a civil rights violation for an employer to refuse to hire someone based on a conviction record unless there is a “substantial relationship” between the offense and the job, or hiring would pose an unreasonable risk to property or safety.⁸ A theft conviction can disqualify you from a banking job while leaving a warehouse position open. Licensed professions are harder: healthcare, education, and law enforcement often become inaccessible after a felony conviction.

Housing

Public housing authorities administering Section 8 and other federal programs run criminal background checks and can deny admission based on criminal history. Lifetime sex offender registrants are automatically barred. For other felony convictions, the authority has discretion, but the applicant must be notified of a record found in the background check and given a chance to dispute its accuracy and relevance before denial is final.⁹ Private landlords set their own screening policies, and many exclude felony convictions.

Immigration

Non-citizens carry the heaviest additional risk. Federal immigration law makes a person deportable if convicted of a crime involving moral turpitude within five years of admission when the offense carries a potential sentence of one year or more.¹⁰ Two or more convictions for crimes involving moral turpitude at any time after admission also trigger deportability. Class 3 felonies clear the one-year threshold easily, and many qualify as crimes involving moral turpitude, which can lead to removal, denial of naturalization, or bars on reentry. If you are not a U.S. citizen, consult an immigration attorney before accepting any plea.

International Travel

A felony conviction can restrict entry to other countries. Canada treats people with criminal records as potentially inadmissible. Entry may 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.¹¹

Sealing a Class 3 Felony Record

Illinois lets certain Class 3 felony convictions be sealed through a Certificate of Sealing issued by the Prisoner Review Board. The conviction must be a one-time Class 3 or Class 4 felony, and you have to wait at least five years from the end of your sentence or five years from your last arrest, whichever is later.¹² Sealing hides the record from most background checks, though law enforcement and certain state agencies keep access.

Not every Class 3 qualifies. Sex offenses, crimes of violence, domestic violence offenses, gun offenses, and DUIs are all excluded. Theft, deceptive practices, forgery, possession of burglary tools, and drug possession are specifically listed as eligible.¹² For a drug offense, you’ll need to complete a treatment program and file proof of completion with your petition. Sealing isn’t automatic. You file a petition, the Board reviews it, and the Board can deny.
