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

Overview

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

In Colorado, the statute of limitations (SOL) sets a deadline for the state to file criminal charges after an alleged offense occurs. For the most serious category in many prosecutions—a Class A felony (often referred to as “1st degree felony” in everyday language)—Colorado generally uses a longer limitations period than for lower-level felonies.

This page focuses on Colorado’s SOL rules for a Class A felony and the practical scenarios that can extend, toll, or restart that deadline. It also shows how to use DocketMath’s SOL calculator so you can model timelines with key case events (like arrest dates and tolling circumstances).

Limitation period

Baseline deadline for a Class A felony in Colorado

Colorado’s general rule for felony SOLs is set by statute. For Class A felonies, the limitations period is typically:

• Six years (6) for prosecution after the offense, under Colorado’s felony SOL framework.

Because this is a “deadline to prosecute,” the key date is usually the point when the prosecution is commenced—not necessarily when an investigation begins.

“When does the clock start?” (practical timeline)

The SOL clock typically starts from the date of the commission of the offense. In practical terms, timelines often hinge on:

• The alleged offense date (not the date the victim reported, unless it aligns with the offense date for SOL purposes)
• The date the case was commenced (e.g., filing of charges or other statutorily recognized commencement)
• Any tolling events that pause or extend the deadline

“What changes the output?” (what to track)

When you model SOL with the calculator, small date differences can meaningfully affect the result. Track these items:

• Offense date (required)
• Date charges were filed / prosecution commenced (required for “is it time-barred?” style checks)
• Any claimed tolling basis (optional, but critical when it exists)
• Whether the case includes multiple counts with different classifications (common in multi-count matters)

Key exceptions

Colorado’s SOL rules include exceptions and tolling concepts that can extend the time to prosecute even when the baseline period would otherwise expire. The most common kinds of situations that frequently matter in SOL analysis include:

1) Defendant is unavailable to the state / outside jurisdiction

If a person cannot be located or is otherwise absent, some SOL calculations can be affected by tolling or suspension concepts tied to the defendant’s availability.

2) Identity or other circumstances prevent prosecution

Certain statutory tolling provisions can apply when prosecution is delayed for reasons connected to the defendant or the case circumstances. This is fact-sensitive, especially if the state argues it could not proceed despite diligence.

3) Procedural events (e.g., pending charges, dismissals with re-filing)

Procedural posture can matter—especially if a prior case was filed within the limitations period and later dismissed or refiled. Not every dismissal resets the clock; outcomes can depend on the nature of the dismissal and statutory treatment.

4) Multiple offenses / multiple counts

When a complaint or indictment includes multiple counts, each count can have its own SOL analysis. Even when the overall “case” has one timeline, the legality of charging may differ by count.

Quick checklist of exception inputs (for modeling)

Use the following when running DocketMath’s calculator:

Statute citation

Colorado’s statute of limitations for criminal prosecutions is found in the Colorado Revised Statutes.

For Class A felonies, the controlling provision is the statute that sets felony limitation periods by class and severity, including the six-year (6) limitations period for Class A felonies.

• C.R.S. § 16-5-401 — Colorado statute of limitations for criminal offenses (includes time periods applicable by felony class, including Class A).

Additionally, Colorado’s SOL framework includes provisions addressing tolling/suspension concepts within the broader limitations chapter.

• C.R.S. §§ 16-5-401 through 16-5-407 — general limitations structure and related timing/tolling provisions

Use the calculator

DocketMath’s statute-of-limitations tool is designed to turn case dates into a clear timeline answer. For a Colorado Class A felony, you can use it to evaluate whether the prosecution appears to fall within the baseline limitations period and to model how tolling inputs change the result.

Step-by-step: modeling a Colorado Class A felony SOL

1. Open: /tools/statute-of-limitations
2. Select:

   • Jurisdiction: **Colorado (US-CO)
   • Offense classification: Class A felony
3. Enter required dates:

   • Offense date (the date alleged conduct occurred)
   • Filing / commencement date (the date charges were filed or prosecution commenced per the calculator’s method)
4. If applicable, enter tolling-related dates or triggers:

   • The tool may provide specific toggles or prompts depending on its configuration
5. Review the output:

   • Baseline expiration date
   • Whether the filing date falls before or after expiration
   • Any adjusted expiration date if tolling is modeled

How outputs change when inputs change

Here’s the practical impact you’ll see:

Example timeline (illustrative only)

If you enter:

• Offense date: Jan 10, 2020
• Commencement/filing date: Jan 15, 2026

With a six-year baseline, the expiration date would fall around Jan 10, 2026 (exact day-level computation depends on the tool’s method). In that example, a filing on Jan 15, 2026 would likely be after the baseline deadline—unless tolling/exception inputs adjust the expiration date.

Use the tool for consistent case review

The calculator is also useful for:

• Comparing multiple counts within the same case (each count can have a different offense date)
• Running “what if” timelines based on competing factual dates (e.g., two alleged conduct dates)

Sources and references

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