Statute of Limitations for Rape / Sexual Assault (adult victim) in Washington
6 min read
Published March 22, 2026 • By DocketMath Team
Overview
In Washington, the statute of limitations for bringing criminal charges for adult rape and other adult sexual assault offenses is governed primarily by RCW 9A.04.080. The default limitations period is 5 years, but Washington law includes specific exceptions that can shorten that period to 3 years in defined circumstances.
DocketMath’s statute-of-limitations calculator helps you turn those rules into an actionable timeline—especially when you know (or can estimate) the date of the alleged offense and the date charges were filed (or the date you’re evaluating). This is not legal advice; it’s a structured way to understand how the statutory clock is typically analyzed in Washington.
Note: The “statute of limitations” timeline is a procedural rule about when prosecution must be filed. It does not decide guilt or innocence, and it can be affected by case-specific facts and procedural events.
Limitation period
Default rule: 5 years
For adult victims, Washington’s general limitation framework for certain felony prosecutions runs for 5 years under RCW 9A.04.080.
Practically, that means:
- Start point (baseline): the statutory clock begins to run from the date of the alleged offense (not the date you report it, unless a specific rule changes that).
- End point (baseline): the state must file the charging document (or otherwise initiate prosecution within the period recognized by the statute).
If you’re comparing timelines, use this quick check:
- If charges were filed more than 5 years after the alleged offense date, the claim that prosecution is time-barred becomes more plausible under the default rule.
- If charges were filed within 5 years, the limitations defense usually hinges on whether a statutory exception (like a 3-year cap) applies.
How the calculator changes results
With DocketMath, your output changes based on which statutory classification/exception you select and the dates you input.
Common ways users “move the needle” in the calculation:
- Changing the offense date by even a few months can shift whether filing falls inside or outside the period.
- Selecting the correct exception can change the period from 5 years to 3 years, which materially affects the outcome for borderline dates.
Key exceptions
Washington’s limitations statute includes exceptions that can reduce the limitations period from 5 years to 3 years.
Based on the jurisdiction rules provided for this calculator:
- Exception P1: 5 years (this is not a shortening; it confirms the 5-year baseline applies for that category)
- Exception V1: 3 years (applies in defined circumstances under RCW 9A.04.080(1)(j))
- Exception V2: 3 years (a separate 3-year classification listed for this calculator context)
What “3 years” means for timeline planning
Where a 3-year exception applies, the practical threshold becomes:
- Charges filed after 3 years from the alleged offense date may fall outside the allowed time window for that category.
- Charges filed within 3 years are generally treated as timely under the shortened period—though other procedural doctrines could still affect timing in real cases.

Warning: Exceptions are offense- and fact-dependent. A mismatch between the selected category and the actual statutory classification can produce a misleading “timely/untimely” result.
Statute citation
Washington’s statute of limitations framework for these prosecutions is set out in:
- RCW 9A.04.080 — 5 years (general period, with exceptions)
- RCW 9A.04.080(1)(j) — 3 years (exception V1)
The calculator’s Washington rules are summarized here for quick reference:
| Rule label | Statutory hook | Limitation period |
|---|---|---|
| General baseline (P1) | RCW 9A.04.080 | 5 years |
| V1 exception | RCW 9A.04.080(1)(j) | 3 years |
| V2 exception | (3-year exception listed for calculator context) | 3 years |
If you want to verify which portion of RCW 9A.04.080 is implicated, treat the citations above as your starting map—then confirm the charging category against the specifics of the case record.
Use the calculator
DocketMath’s statute-of-limitations calculator is designed to produce a clear timeline outcome based on Washington’s RCW 9A.04.080 rules.
What you’ll typically enter
When you use /tools/statute-of-limitations, you’ll generally work with:
- Offense date (date alleged conduct occurred)
- Filing date (date charges were filed), or a date you’re evaluating against
- Applicable limitations category/exception (to choose between 5 years vs 3 years rules)
To get started quickly, you can also open the tool here: **/tools/statute-of-limitations
How outputs change with your inputs
Here’s what to expect when you adjust key inputs:
- If you move the offense date forward while holding the filing date constant, the time between offense and filing decreases—making it more likely the filing is within the limitation period.
- If you select a 3-year exception (V1 or V2) instead of the 5-year baseline, the “latest permissible” filing date moves earlier by roughly 2 years compared to the 5-year rule.
- If you only know the filing year (not the exact day), the calculator may give a practical threshold based on your best available dates—use additional precision if you have it.
Practical “timeline math” example
To understand how the clock comparison works conceptually (without relying on legal conclusions):
- Under the default rule: latest permissible filing date ≈ offense date + 5 years
- Under a 3-year exception: latest permissible filing date ≈ offense date + 3 years
So, for a hypothetical offense date of January 15, 2021:
- 5-year threshold would fall around January 15, 2026
- 3-year threshold would fall around January 15, 2024
If your case filing date is mid-2025, it may fit within 5 years but not within 3 years—which is why selecting the correct exception category matters.
Pitfall: People often assume “reporting date” controls the clock. Under RCW 9A.04.080, the analysis generally anchors on the offense date unless a specific rule changes timing in the way applied to the case.
