Overview

Run this scenario in DocketMath using the Statute Of Limitations calculator.

In Wisconsin, the time the state has to file criminal charges depends on the offense classification and the facts of when the alleged conduct occurred. For a Class B misdemeanor, the statute of limitations (SOL) is 6 years under Wis. Stat. § 939.74(1).

DocketMath’s statute-of-limitations tool can help you translate that rule into a usable deadline (for example, identifying what date starts the clock and how changes to that input affect the estimated “latest filing” date). This post explains the core rule and the most common planning variables—without providing legal advice.

Note: SOL rules are procedural timing limits. They don’t erase the underlying allegations, and they can be affected by specific case events that occur after the alleged offense.

Limitation period

Baseline rule for Class B misdemeanors

For a Class B misdemeanor in Wisconsin, the SOL is:

6 years from the relevant start date under **Wis. Stat. § 939.74(1)

That means the state generally must commence the prosecution within 6 years of the date that triggers the limitation period (more on “start” and “interruptions” below).

What DocketMath needs to calculate a deadline

When you use DocketMath’s statute-of-limitations calculator (/tools/statute-of-limitations), you typically provide inputs such as:

Offense date (or the earliest date conduct occurred)
(Sometimes) case context that affects the start date or special treatment of timing

Your output will usually be expressed as:

Latest likely SOL date for commencing prosecution (based on the provided inputs)

To try it, go to: /tools/statute-of-limitations

How the output changes with inputs

Even small changes to the starting date can shift the deadline by years. Here’s how to think about it:

If you enter an offense date that is earlier, the SOL “latest filing” date moves earlier as well.
If you enter a later offense date (e.g., when the alleged conduct spans multiple dates), the SOL “latest filing” date moves later.

Because the tool is only as accurate as the date you input, it’s useful to:

Identify the earliest alleged conduct date supported by the record
If the allegations span time, consider using the earliest date that the charging theory could treat as the conduct date (or run scenarios if you have multiple plausible timelines)

Pitfall: Some charging documents describe conduct over a range of dates. If you enter only the “end date” of the range, you may calculate a later SOL deadline than what would apply if the state relies on earlier conduct dates.

Practical workflow for timing review

A simple, repeatable approach is:

Key exceptions

Wisconsin’s SOL statute contains rules that can change how the timeline works. The “6 years” baseline is the starting point, but exceptions and case-specific timing events can affect whether an SOL issue is meaningful.

Wisconsin SOL framework: not a single “simple” clock

Under Wis. Stat. § 939.74(1), the legislature established different limitation periods for different offense categories and included specific exceptions and rules for when time limits apply.

For Class B misdemeanors, the core limit is 6 years, but your deadline may be influenced by events captured by the statute’s exception framework.

“Exception V2” note in the statute framework

In the SOL data used for the calculator logic, Wis. Stat. § 939.74(1) is described as:

6 years — exception V2

This indicates that the statute’s limitation period may include a particular exception path labeled as V2 in the tool’s implementation logic. In practice, this often corresponds to situations where the statute’s general rule is modified by statutory details rather than by the plain “6-year-from-the-offense-date” assumption.

Because SOL litigation and exceptions can be fact- and document-dependent, the most practical way to use this is:

Run the calculator with the facts you have
Treat the output as a timing estimate until you map it against what the charging and procedural history show

Warning: SOL calculations can be derailed by how the “commencement” timing is recorded in the case. A precise answer often depends on procedural dates (e.g., when prosecution is formally commenced).

What to look for in the case record

If you’re trying to understand whether SOL timing matters, look for:

If you have those details, DocketMath can help you convert them into a clean timeline comparison quickly.

For this Wisconsin Class B misdemeanor SOL baseline, the calculator logic references:

Suggested inputs for a Class B misdemeanor review

To align with the 6-year rule:

What you’ll get

After you enter the relevant date inputs, DocketMath’s statute-of-limitations calculator will produce:

A computed SOL deadline date based on the 6-year limitation period in **Wis. Stat. § 939.74(1)

Turning the result into a timeline check

Once you have the computed deadline, compare:

SOL deadline (from DocketMath)
Date prosecution was commenced (from your case documents)

If the prosecution commenced after the calculated deadline, that’s a strong trigger for further review of timing—again, this post is informational and not legal advice.
