How Release Dates Are Calculated in Wisconsin

If you or someone you love is doing time in Wisconsin, the release date depends almost entirely on what the judge ordered in the bifurcated sentence. Wisconsin adopted Truth in Sentencing in 1999, replacing its parole-based indeterminate system with a two-part structure: a confinement period (served in prison) and an extended supervision period (served in the community). The court sets both at sentencing. The confinement period is served in full - there is no traditional good time or earned credit that reduces it for cases under the Truth in Sentencing system. Extended supervision follows automatically. For older cases from before December 31, 1999, the traditional parole and good time system still applies.

This guide walks through how Wisconsin calculates a release date step by step: the bifurcated sentence structure, how the confinement period is calculated, extended supervision and what happens during it, revocation of extended supervision, the older parole-based system for pre-1999 cases, Class A felony life sentences, and what the Wisconsin records office computes at admission. None of this is legal advice, but it will help you read your own time the way the Wisconsin Department of Corrections does.

Here is the short version.

For crimes committed on or after December 31, 1999, Wisconsin uses bifurcated sentences. The judge imposes two components: a term of initial confinement in prison, and a term of extended supervision in the community. These two periods together cannot exceed the statutory maximum for the felony class. The confinement period is served in full. The only deduction from the confinement period is sentence credit for time spent in jail before sentencing (if awarded by the court). There is no traditional good time program that reduces the confinement period under the Truth in Sentencing system. Extended supervision begins automatically when the confinement period ends. Violating extended supervision can result in revocation and reconfinement for up to the balance of the sentence. For crimes committed before December 31, 1999, the older indeterminate system applies: good time credits and parole administered by the Wisconsin Parole Commission.

Step one: the bifurcated sentence structure

Wisconsin's Truth in Sentencing Act (TIS) took effect for crimes committed on or after December 31, 1999. It fundamentally changed sentencing by replacing indeterminate sentences with a two-part (bifurcated) structure.

The judge at sentencing imposes two components:

Confinement period: the time the person will serve in a state prison. This is the prison portion of the sentence.

Extended supervision period: the time the person will serve in the community under supervision after release from prison.

Together, the confinement period and the extended supervision period form the total sentence. That total cannot exceed the statutory maximum for the felony class. For example, a Class C felony has a maximum total sentence of 40 years; the judge might impose 20 years of confinement followed by 5 years of extended supervision (25 years total), which is within the 40-year maximum.

The extended supervision period has a statutory minimum by class that cannot be reduced. For Class B felonies, extended supervision is at least 10 years. For Class C, D, and E felonies, it is at least 5 years. For Class F, G, and H felonies, it is 3 years. For Class I felonies, it is 2 years. The judge may impose more than the statutory minimum.

For Class A felonies (first degree intentional homicide and certain other most serious crimes), the sentence is life imprisonment. Class A felony sentencing has its own structure described in Step six.

Step two: confinement period - served in full

Under Wisconsin's Truth in Sentencing system, the confinement period is served in full. There is no traditional good time program that reduces the confinement period.

The one deduction available under TIS is sentence credit: credit for time spent in custody before the sentence begins - time in county jail awaiting trial or sentencing, if the sentencing court grants it. This pre sentence jail credit is applied to the confinement period and reduces the date of release to extended supervision.

The Wisconsin Department of Corrections records staff calculate the extended supervision date (the date the confinement period ends and extended supervision begins) by taking the maximum term of confinement imposed by the court and reducing it by any sentence credit awarded.

Consecutive sentences: when multiple sentences are imposed consecutively, records staff treat all consecutive sentences as one continuous sentence. The person serves all confinement periods before any extended supervision period begins.

Step three: extended supervision

Extended supervision is the community-based supervision period that follows release from the confinement period. It is not parole in the traditional sense - the person does not need to appear before a parole board to be released to extended supervision. Release is automatic when the confinement period ends.

Extended supervision is supervised by the Wisconsin Department of Corrections. The court sets the conditions of extended supervision at sentencing, and the Department of Corrections may add administrative conditions. Conditions typically include reporting requirements, drug and alcohol testing, restrictions on travel and associations, employment requirements, and any specialized treatment or programming.

The extended supervision period has a specified end date - the maximum discharge date - set by adding the extended supervision term to the release from confinement date. On the maximum discharge date, the person is fully discharged from state supervision.

Step four: revocation of extended supervision

If the person violates the conditions of extended supervision, the Department of Corrections can initiate a revocation proceeding.

A revocation hearing is held before a reviewing authority. If revocation is ordered, the person may be reconfined in prison. The period of reconfinement can be up to the entire remaining sentence - that is, the entire sentence less the time already served in custody prior to release to extended supervision.

The maximum discharge date is recalculated after revocation by adding the remaining sentence to the date the person was taken back into custody, then subtracting any credit received.

Revocation does not extend the sentence beyond the original court-imposed total. The person cannot be held beyond the maximum discharge date calculated from the original sentence.

Step five: pre-1999 cases - the older parole system

For persons serving sentences for crimes committed before December 31, 1999, Wisconsin's older indeterminate sentencing and parole system applies.

Under the older system, courts imposed indeterminate sentences with a maximum term. Good time credits - earned through good conduct - reduced the sentence and produced a mandatory release date. The Wisconsin Parole Commission administered discretionary parole for these cases.

For a life sentence under the older system: the inmate was eligible for discretionary parole after serving 11 years and 3 months (for cases not subject to specific acts that raised the minimum). For cases subject to 1983 Wisconsin Act 528 where the court ordered parole eligibility, the minimum was 13 years and 4 months or a later date ordered by the court.

These legacy cases represent a smaller and shrinking population of people in Wisconsin prisons. Records staff compute parole eligibility dates, projected release dates, and projected discharge dates for these inmates in accordance with the old statutory framework.

The Wisconsin Parole Commission (not the court) has authority over parole decisions for pre-1999 cases. The Commission also has a special action release program to relieve overcrowding by releasing select eligible non-bifurcated inmates.

Step six: Class A felonies and life sentences

Class A felony convictions (which include first degree intentional homicide and certain other most serious crimes) result in a mandatory sentence of life imprisonment.

For Class A felony life sentences, the sentence is technically a bifurcated sentence: the court imposes a term of confinement in prison and a term of lifetime extended supervision. The confinement period must be served before extended supervision begins, and the court may set a parole eligibility date or deny parole eligibility as part of the sentence.

If the court sets a parole eligibility date, the Wisconsin Parole Commission may consider conditional release at that date. If parole is denied or no parole eligibility date is set, the person serves the confinement period until death or until the court or Commission authorizes release.

Life without parole (where the court does not set any parole eligibility): the person serves the sentence for life with no release mechanism through the Commission.

Putting it together: a worked example

Here is how the pieces fit, using examples. None of these numbers are legal advice, but they show the method.

Take a person sentenced for a Class C felony (maximum 40 years total) committed in 2010. The judge imposes 10 years of confinement and 5 years of extended supervision. The records staff apply any sentence credit (for example, 6 months of pre sentence jail credit). The resulting extended supervision date is 9.5 years from the start of the sentence. At that point, the person is released automatically to extended supervision for 5 years. If extended supervision is completed without violation, the maximum discharge date is 14.5 years from the start of the sentence.

If the person violates extended supervision at 3 years of supervision, they could be reconfined for up to the remaining 2 years of supervision balance. Revocation cannot extend the sentence beyond the original total.

The bottom line for Wisconsin

Wisconsin's release date for post-1999 crimes is set almost entirely by the judge at sentencing. The confinement period is served in full. There is no traditional good time program under Truth in Sentencing. The only deduction is pre sentence jail credit. Extended supervision follows automatically and is served in the community. Revocation can result in reconfinement but cannot extend beyond the original court-imposed total. For pre-1999 cases, the older parole and good time system applies through the Wisconsin Parole Commission.

The practical takeaways are clear. First, for bifurcated TIS sentences, the release date to extended supervision is fixed at the court-imposed confinement period minus jail credit - understand that number precisely. Second, extended supervision conditions must be followed carefully because revocation can mean return to prison for a substantial period. Third, the maximum discharge date (end of extended supervision) marks the end of all state supervision. Ask the Wisconsin Department of Corrections records office for the current extended supervision date and maximum discharge date.
