A felony conviction in Wisconsin can cost you anywhere from three and a half years to the rest of your life behind bars. The end you land on depends on a single letter. Every felony in the state is classified into one of nine categories, A through I. This category sets the maximum prison time and fine before a judge weighs the specifics of your case.

The Nine Classes and What Each One Carries

Wisconsin’s felony penalties are outlined in Wis. Stat. § 939.50. The severity of penalties increases as you move down the alphabet:

• Class A – Life imprisonment for the most severe crimes, such as first-degree intentional homicide.
• Class B – Up to 60 years in prison without a fine.
• Class C – Up to 40 years in prison and a maximum fine of $100,000.
• Class D – Up to 25 years in prison, with a maximum fine of $100,000.
• Class E – Up to 15 years in prison and a maximum fine of $50,000. 
• Class F – Up to 12 years, 6 months in prison, and a maximum fine of $25,000.
• Class G – Up to 10 years in prison with a maximum $25,000 fine. 
• Class H – Up to 6 years in prison and a $10,000 maximum fine. 
• Class I – Up to 3 years, 6 months and a $10,000 maximum fine, the lowest tier of felony offenses.

Not every felony fits neatly into this grid. Some unclassified felonies have their own maximum sentences written into individual statutes, so the letter is not always the whole story.

Prison Time Is Only Half of Your Sentence

Wisconsin uses truth-in-sentencing. Under Wis. Stat. § 973.01, a felony prison sentence is split into two parts: a term of confinement followed by a period of extended supervision in the community. Adding them together gives you the total sentence.

Two things surprise most people: there is no parole for these sentences, and you serve the full sentence without time off for good behavior. The number of years the judge announces is the number of years you will serve in prison.

Enhancers Can Raise the Ceiling

The class maximum is just a starting point and not a guarantee. In Wisconsin, prosecutors can stack sentence enhancers:

• If you are a repeat offender, you could face additional years under the habitual criminality statute (Wis. Stat. § 939.62).
• If you commit a felony while armed, you could add up to five more years (Wis. Stat. § 939.63).

Domestic-abuse and hate-crime enhancers push the numbers even higher. Two charges from the same class can result in very different sentences if enhancers are involved.

The Costs That Follow You Home

A felony extends beyond the sentence itself. A conviction suspends your right to vote until you complete your entire sentence, including supervision and re-registration. It strips you of your right to possess firearms. It can close doors to jobs, housing, and professional licenses for years.

Talk to a Lawyer Before You Talk to the Court

Knowing your felony classification tells you what you are facing. It doesn’t tell you how to fight it. The gap between a Class F charge and a Class H, or between a plea and dismissal, often comes down to the work done early, before your first court date.
