What Is a Class I Felony in Wisconsin? Penalties and Lasting Consequences

A Class I felony in Wisconsin is the state’s least severe felony classification, carrying a maximum penalty of 3 years and 6 months of imprisonment, a $10,000 fine, or both.¹ “Least severe” is relative. A conviction still permanently bans you from owning a firearm, strips your right to vote during your sentence, and leaves a public record that follows you through job applications and housing searches for years afterward.

What Crimes Fall Under Class I

Class I covers conduct that sits above misdemeanor-level harm but below the more serious felony classes. Typical charges involve moderate financial loss, physical harm short of severe injury, or repeat drug violations.

Theft of property worth between $2,500 and $5,000. Below $2,500 the offense is generally a misdemeanor; above $5,000 it jumps to a higher felony class.²
Stalking, meaning a pattern of conduct directed at a specific person that would cause a reasonable person to fear bodily harm or suffer serious emotional distress. Stalking can be charged as a higher felony class when aggravating factors are present, such as a prior stalking conviction or a credible threat of death.³
Substantial battery, meaning intentionally causing bodily harm that is significant but falls short of “great bodily harm.”⁴
Second or subsequent drug possession. A first conviction for possessing cocaine, amphetamine, LSD, psilocybin, or THC is typically a misdemeanor. A second conviction becomes a Class I felony, and the prior offense can be any drug-related conviction under state or federal law.⁵

How the Prison Sentence Is Structured

The 3.5-year maximum is a ceiling, not an automatic outcome. When a judge does impose prison time for a felony, Wisconsin requires a “bifurcated sentence” that splits the total into two parts: initial confinement served behind bars, followed by extended supervision served in the community.⁶

For a Class I felony, the confinement portion cannot exceed 1 year and 6 months, and the extended supervision portion cannot exceed 2 years.⁶ Extended supervision must last at least 25% as long as the confinement period. If a judge orders the maximum 18 months of confinement, supervision must run at least 4.5 months and can stretch to the full 2 years.

During extended supervision you report to a supervision agent, follow conditions set by the court and the Department of Corrections, and stay out of trouble. Violate those conditions and you can be sent back to prison for the remaining supervision time.

When Probation Replaces Prison

Prison is not the only path. For most Class I felonies, the judge can place you on probation instead of imposing a bifurcated sentence.⁷ You serve the sentence in the community under conditions that often include regular meetings with a probation officer, drug testing, community service, or treatment.

Probation for a Class I felony must last at least one year and can run up to 3 years and 6 months, whichever is greater between the statutory maximum imprisonment or three years.⁷ A judge can also impose up to one year of county jail time as a condition of probation. Jail as a probation condition is not the same as a state prison sentence under the bifurcated system. First-time Class I defendants frequently receive probation rather than prison.

Penalty Enhancers for Repeat Offenders

The 3.5-year maximum assumes no significant criminal history. If you qualify as a “repeater” under Wisconsin law, the ceiling climbs. You are a repeater if you were convicted of a felony within the five years before the current offense, or if you have three separate misdemeanor convictions within that same window.⁸

Because a Class I felony carries a maximum of more than one year but no more than ten, the repeater enhancer adds up to 2 extra years when the priors are misdemeanors and up to 4 extra years when the prior is a felony.⁸ A repeat felon facing a Class I charge could be looking at up to 7.5 years total. Time spent in prison does not count toward the five-year lookback window, so the clock effectively pauses while you are behind bars.

Fines, Surcharges, and Court Costs

The $10,000 maximum fine is only part of the financial picture. Wisconsin imposes mandatory surcharges and court costs on every felony conviction, including the crime victim and witness assistance surcharge, the justice information fee, the court support services surcharge, and the DNA surcharge. These add several hundred dollars beyond the fine itself and are not subject to the judge’s discretion.

Consequences That Outlast the Sentence

Finishing your sentence does not erase the conviction. The downstream effects often cause more lasting damage than the fine or confinement.

Permanent Firearm Ban

Any felony conviction in Wisconsin triggers a lifetime ban on possessing a firearm. Violating that ban is itself a Class G felony, a more serious charge than the original Class I offense.⁹ Federal law adds a parallel ban on anyone convicted of a crime punishable by more than one year of imprisonment.¹⁰ A Class I felony clears that federal threshold easily. The only route to restoring firearm rights under Wisconsin law is a governor’s pardon.

Voting Rights

A felony conviction disqualifies you from voting for the entire duration of your sentence, including any probation or extended supervision.¹¹ Rights are restored once you have fully completed the sentence, and you will need to re-register.

Employment and Housing

Felony records are public in Wisconsin and surface on routine background checks. Federal equal employment guidelines require employers to assess whether your criminal history actually relates to the job rather than impose blanket bans, and employers must give you a chance to explain the circumstances before rejecting you.¹² In practice, many employers quietly move on. Certain professional licenses can also become harder to obtain, depending on whether the licensing board considers the conviction related to the profession.

International Travel

A felony can complicate international travel. Canada routinely screens visitors for criminal records and can deny entry to anyone whose offense would qualify as a serious crime under Canadian law. A process called criminal rehabilitation may eventually remove that bar, but it requires waiting at least ten years after completing your full sentence and filing an application. Other countries maintain their own restrictions, so checking entry requirements before booking is worth the effort.

Expungement: A Narrow Window

Wisconsin’s expungement rules are tighter than most people assume. A Class I felony conviction can be expunged, but only if several conditions line up, and you have to plan for it from the moment of sentencing.

You must have been under 25 at the time of the offense. The judge must order expungement at sentencing itself; you cannot come back later and ask for it. You must successfully complete your entire sentence, meaning no new convictions and no probation revocations. If all three line up, the authority supervising your sentence issues a certificate of discharge that triggers the expungement.¹³

There are hard disqualifiers. Expungement is not available if you have any prior felony conviction, or if the offense is classified as a violent crime.¹³ Substantial battery, for instance, would likely fall under the violent-offense exclusion even though it is a Class I felony. If you are a first-time offender under 25 facing a non-violent Class I charge, raising expungement at sentencing is critical. Miss that window and the conviction stays on your record permanently, no matter how well you do afterward.
