Statute of Limitations for Class A / 1st Degree Felony in Idaho

5 min read

Published March 22, 2026 • By DocketMath Team

Overview

In Idaho, the statute of limitations (SOL) sets a deadline for the State to file criminal charges. For many offenses, the deadline is governed by a general limitations rule found in Idaho Code § 19-403.

For class A / 1st degree felonies, DocketMath uses the general/default SOL period unless a specific statutory exception applies. Based on the information available here, no class- or claim-type-specific sub-rule was identified, so this article explains the default rule rather than an offense-specific carve-out.

Note: SOLs generally control when charges may be filed, not whether an event can be discussed or used as background evidence in a later case.

Limitation period

General SOL period in Idaho: 2 years

Under the general limitations framework, the State generally must commence prosecution within two (2) years of the date the offense is committed. DocketMath’s statute-of-limitations calculator is designed to turn that rule into a timeline you can work with—especially useful when you’re trying to determine whether an alleged offense date is inside or outside the filing window.

How the SOL timeline typically works (practical view)

You’ll usually start with:

  • Offense date (the “clock start” for the general rule in most SOL analyses)
  • The general SOL length (2 years for the default rule discussed here)

Then the calculator estimates a latest filing date by adding the SOL duration to the offense date.

Quick example (default 2-year rule)

If the offense occurred on January 10, 2024, then under the default general period:

  • The two-year window runs to about January 10, 2026 (subject to standard computation rules the calculator applies)

The closer you get to the cutoff date, the more that calculation precision matters—especially if tolling or an exception applies.

Inputs that change outputs in DocketMath

When you use the DocketMath tool, your main inputs typically affect outputs like the estimated expiration date and whether a prosecution date falls “within” or “outside” the period.

Common inputs to consider:

  • Date of offense (required)
  • Date charges were filed / prosecution began (optional, if you want a pass/fail comparison)
  • Any date-based adjustments the tool supports for exceptions (see next section)

Key exceptions

Even when the default SOL is 2 years, exceptions can alter the timeline. The most impactful exceptions usually fall into categories like:

  • Tolling (pausing the clock)
  • Different triggering events (where the “start” date is not the offense date for SOL purposes)
  • Special circumstances that statute specifically recognizes

Because this page is focused on the general/default rule and no additional class A / 1st degree-specific sub-rule was identified here, you should treat 2 years as the baseline and then check whether any statutory exception could apply to the facts.

Warning: A limitations issue can hinge on details such as whether a statutory tolling condition exists, whether the prosecution was “commenced” within the meaning of Idaho law, and how the SOL computation is handled for the specific situation.

What to do if you suspect an exception

To use the calculator effectively, gather:

  • Dates related to any alleged “tolling” condition (for example, periods relevant to statutory pauses or delays)
  • Any dates that may be argued as the correct “start” for the limitations analysis
  • The most defensible offense date you have (and the reason for that date, if disputed)

Then input those facts into DocketMath’s calculator so you can see how the estimated expiration date shifts compared to the baseline 2-year rule.

Statute citation

The general statute of limitations period discussed in this page is:

  • Idaho Code § 19-403 — establishes the general limitations period used for many Idaho criminal offenses, including the default framework applied here.

Also note the general SOL period used here is 2 years, matching the jurisdiction data provided for Idaho in this briefing.

Primary CTA

What you’ll see when you run it

Typically, the calculator output helps you answer questions like:

  • What is the estimated SOL expiration date for the offense date?
  • If you enter a filing/commencement date, does it fall:
    • Before the expiration date, or
    • After the expiration date?

How output changes with inputs

Consider this cause-and-effect relationship:

  • If you input an earlier offense date, the expiration date moves earlier.
  • If you input a later offense date, the expiration date moves later.
  • If you input a different computation assumption (such as an exception/tolling adjustment supported by the tool), the expiration date can move accordingly.

Gentle disclaimer

This calculator provides a structured, date-based estimate using the rules you input. SOL application can depend on case-specific facts and legal interpretation, so treat the results as a timeline aid, not a final legal conclusion.
