Statute of Limitations for Class C / Petty Misdemeanor in Washington

5 min read

Published March 22, 2026 • By DocketMath Team

Overview

In Washington, the statute of limitations sets a deadline for how long the state has to file a criminal case after an alleged offense. For a Class C / petty misdemeanor offense, the default limitation period is typically measured in years, not months—and it directly affects whether a prosecution is time-barred.

DocketMath’s statute-of-limitations calculator helps you work out the relevant deadline using the filing date and the offense date (and, when applicable, any special exception rules). This walkthrough explains the applicable Washington rules using RCW 9A.04.080 as the controlling statute for most misdemeanor timing questions.

Note: A statute of limitations analysis depends on the specific charge and the exact dates (including whether certain triggering events apply). The calculator is a practical estimator for the deadline, not a substitute for case-specific legal review.

Limitation period

For Washington misdemeanor offenses, RCW 9A.04.080 supplies the general rule. For Class C / petty misdemeanor offenses, the default SOL period is 5 years.

Here’s the practical “default timeline” concept most people use:

  • Start point (offense date): The clock generally begins on the date the offense is committed.
  • End point (deadline to file): The prosecution must be commenced within the limitation period.
  • Consequence of missing the deadline: If the state files outside the permitted time window (and no exception applies), the defense may seek dismissal based on the statute of limitations.

How the calculator output changes

DocketMath uses your inputs to compute the latest potential deadline. Two factors usually drive differences in the result:

  1. The offense date you enter
    Moving the offense date forward shifts the computed deadline forward by the same amount.

  2. Whether an exception applies
    If an exception reduces the limitation period, your deadline can drop from the 5-year default to a shorter period (see “Key exceptions”).

Key exceptions

Although the headline rule for Class C / petty misdemeanors is 5 years, RCW 9A.04.080 also includes sub-rules that can shorten the time limit in specific circumstances.

Based on the Washington data used for DocketMath’s calculator ruleset, the exceptions include:

  • Exception P1:

    • RCW 9A.04.080 — 5 years — exception P1
    • This is a classification that still results in a 5-year period, but it can matter for how a charge is categorized by the system.
  • Exception V1 (special shorter period):

    • RCW 9A.04.080(1)(j) — 3 years — exception V1
    • In situations that fit the statute’s subsection language tied to this category, the SOL is 3 years rather than 5.
  • Exception V2 (another shorter period category):

    • The dataset indicates null — 3 years — exception V2.
    • In practice, this indicates the calculator can switch to a 3-year limitation period under a second identified classification path.

What to do with the exceptions (practical workflow)

Use this checklist before relying on the deadline the calculator generates:

  • If you select an exception that applies a 3-year limit, your filing deadline will move earlier compared to the 5-year baseline.

Warning: Don’t assume a 5-year limit automatically applies. RCW 9A.04.080 includes subsection-specific rules (including RCW 9A.04.080(1)(j)) that can shorten the SOL to 3 years when the charge fits that category.

Statute citation

Washington’s statute of limitations timing rule for these misdemeanor questions is primarily found in:

  • RCW 9A.04.080 — Washington’s general statute of limitations for criminal offenses
    • Default for the relevant misdemeanor category: 5 years
    • Shorter exception referenced in the dataset: RCW 9A.04.080(1)(j)3 years

DocketMath’s calculator logic is designed around these statutory time periods so you can quickly determine the outer deadline to commence a case, given your offense date and the applicable category/exception.

Use the calculator

To compute the deadline using DocketMath, go to: **/tools/statute-of-limitations

What you’ll typically input

In the calculator, you’ll generally provide:

  • Offense date (the date the alleged conduct occurred)
  • Case type / offense category (so the tool selects the right baseline rule)
  • Exception selection (if applicable) (so the tool can switch between 5 years and 3 years where appropriate)

Example of how outputs shift

Assume you enter the same offense date in two runs:

  • Run A uses the default misdemeanor period: 5 years
  • Run B uses a shorter exception category tied to 3 years (e.g., RCW 9A.04.080(1)(j) in the dataset)

The output changes as follows:

  • The 3-year deadline will be 2 years earlier than the 5-year deadline, using the same offense date.
  • If you’re comparing “filed on” dates, that 2-year difference can determine whether the filing is within the SOL window.

For a quick workflow:

  • Compute with the 5-year rule first.
  • If your charge matches an exception category, re-run with the exception so the tool applies RCW 9A.04.080(1)(j)-style timing (3 years per the ruleset).
  • Compare the computed deadline to the relevant commencement/filing date shown in your case materials.

A gentle reminder on precision

Different cases can have different “clock start” mechanics depending on the procedural posture and factual context. DocketMath focuses on the statutory limitation period math so you can move faster, but you should still verify the relevant dates in the record.

Sources and references

Start with the primary authority for Washington and confirm the effective date before relying on any output. If the rule has been amended, update the inputs and rerun the calculation.
