Direct answer

In Colorado, the “statute of limitations” clock is generally measured from when a claim accrues, but Colorado law also recognizes tolling events—most commonly for minor plaintiffs and in circumstances involving fraudulent concealment—and some claim types incorporate their own accrual/tolling mechanics inside the limitations statutes. Practically, that means a deadline you compute from the “base” limitations period alone may be extended by the amount of time a recognized tolling mechanism applies.

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

DocketMath can help you model these effects in a jurisdiction-aware way for US-CO, especially when you provide the dates when tolling starts and ends (and the claimant status that triggers tolling).

Note: This post explains common Colorado tolling mechanisms and how to model them. It’s not legal advice—tolling is date-driven and fact-specific.

What you need to know

Before you run any tolling numbers in Colorado, collect inputs that determine (1) the base limitations period and (2) whether anything pauses the clock.

1) Identify the correct limitations period (the “base”)

Colorado limitations periods are claim-type specific. For many common civil claims, the time limits are found in Title 13, Articles 80 and 81 of the Colorado Revised Statutes. Examples of common categories include written and oral contract claims, torts, actions on statutory rights, and personal injury-related claims (often with special rules).

Your first job is picking the correct limitations statute for the claim you’re analyzing. DocketMath’s statute-of-limitations calculator is meant to support this workflow.

2) Determine the accrual date

Colorado uses “accrual” concepts that often track when the injury or breach occurs and—depending on the claim—when it was discovered or should have been discovered. Tolling typically does not replace accrual rules; it modifies how time runs after accrual.

3) Identify tolling events that pause or extend the deadline

Common Colorado tolling themes include:

  • Minority (under age of majority): the limitations period may be paused while the claimant is a minor, subject to statutory mechanics and exceptions.
  • Fraudulent concealment: limitations may be extended where a defendant’s conduct prevents discovery of facts needed to bring the action, with a focus on the statutory concept of facts being “fraudulently concealed.”
  • Other statutory pauses: some claim types incorporate special tolling/accrual provisions inside the limitations statute itself.

4) DocketMath: model “pause” time, not just “end date”

When you use DocketMath, the output changes based on whether tolling:

  • starts on a specific date (e.g., a birthdate-driven event),
  • lasts for a defined duration,
  • ends when a triggering event occurs (e.g., reaching a threshold age or when concealment is lifted/discovery occurs),
  • applies fully or only to certain parts of the claim.

Step-by-step

Use this workflow to toll a statute of limitations in Colorado (US-CO) with DocketMath.

Step 1: Open the DocketMath calculator

Use the primary CTA: /tools/statute-of-limitations.

Step 2: Select the claim category (or the limitations mapping)

Choose the claim type that matches the cause of action you’re analyzing. DocketMath will map that claim to the relevant Colorado limitations period.

Step 3: Enter the accrual date (the starting point)

Add the date the claim accrued for your purposes. If accrual for your claim is tied to discovery or another event, use the accrual date you would apply under the applicable Colorado rule.

Example input set (illustrative):

  • Claim accrual date: 2022-06-01

Step 4: Add tolling based on claimant status (minority)

If the claimant was a minor, model minority tolling.

Typically, you will enter:

  • claimant’s birthdate, and
  • the date you want considered as the end of the tolling period (often when the claimant reaches the age threshold specified by the statute).

DocketMath will compute an adjusted deadline by extending the limitations period by the time the clock is paused under the modeled minority rule.

Pitfall: Don’t assume minority tolling applies automatically to every claim type. Some limitations provisions treat infancy/minority differently, and some statutes have their own timing structure. Make sure the tolling event you model matches the statutory mechanism for the claim.

Step 5: Add tolling based on fraudulent concealment (when applicable)

If you’re modeling a case where the defendant allegedly fraudulently concealed facts needed to bring the claim, use the concealment dates supported by your record:

  • start date of the concealment (or when concealment began), and
  • end date (when the concealed facts were discovered, should have been discovered, or when concealment ended—based on the statute’s operation).

DocketMath can then extend the limitations period by the concealed interval, to the extent the concealment tolling statute applies as measured by Colorado law.

Step 6: Review the calculator output: “baseline vs adjusted”

Check DocketMath for a comparison between:

  • the baseline limitations deadline (no tolling), and
  • the adjusted deadline (with tolling applied).

If the adjusted deadline is later, record which tolling interval created the difference—those details are often the most important for later review.

Step 7: Stress-test with alternate reasonable dates

Because tolling frequently turns on disputed timing (e.g., when concealment ended or when discovery should have occurred), run 2–3 scenarios:

  • earliest plausible tolling start,
  • latest plausible tolling end,
  • “midpoint” timeline.

DocketMath is useful here because you can quickly compare scenario outputs.

Step 8: Export or record your assumptions

Before relying on results, document:

  • accrual date assumption,
  • tolling event dates,
  • whether you modeled one tolling event or multiple.

A small change to a key date can move a deadline by months (or more), so assumptions should be consistent.

Key statutes and citations

Below are common Colorado tolling anchors used when modeling time pauses for civil claims in US-CO.

Tolling conceptColorado citationWhat it typically affects in a limitations calculation
Minority tolling (minor plaintiffs)C.R.S. § 13-81-101Pauses/tolls the limitations period while the claimant is under the statutory age threshold, then resumes when the threshold condition is met (as stated in the statute’s text and operating rules).
Fraudulent concealment / concealment-based tollingC.R.S. § 13-80-108Extends/tolls limitations where the defendant fraudulently concealed facts necessary to bring the action, often measured by discovery or when concealment ends (depending on the statutory language and application).

How to use these citations in practice

  • If your fact pattern involves a minor claimant, start with C.R.S. § 13-81-101 as your first tolling candidate.
  • If your fact pattern involves concealed facts that fit the statutory concept of fraudulent concealment, C.R.S. § 13-80-108 is typically the modeling anchor you’d use in DocketMath.

Warning: Tolling statutes interact with accrual and discovery rules that may be embedded in other limitations provisions. Modeling tolling without correctly setting the accrual date and the timing assumptions for the tolling event can lead to a result that doesn’t track the statute’s actual structure for that claim type.

Common pitfalls

Colorado tolling issues frequently fail on (a) timing precision and (b) wrong statute selection. Watch for these common problems:

  • Using the wrong baseline limitations period

    • Tolling only extends the clock you started with. If the base period is incorrect for the claim category, the adjusted deadline will also be incorrect.
  • Confusing “accrual” with “tolling start”

    • Accrual determines when the clock begins. Tolling determines when the clock pauses/resumes. They are not the same step in the analysis.
  • Overlooking minority threshold mechanics

    • Minority tolling depends on the statutory age threshold in C.R.S. § 13-81-101 and may require specific date inputs (e.g., birthdate and the date the statutory threshold is reached).
  • Modeling concealment using ordinary “concealment” facts rather than statutory fraudulent concealment

    • Not every situation involving withheld information automatically qualifies as statutory fraudulent concealment. Match your timeline to the statutory concept and the discovery/resumption timing described by C.R.S. § 13-80-108.
  • Stacking tolling without checking interactions

    • Multiple tolling mechanisms can sometimes compound the time, but only if they apply concurrently under the relevant statutes to the same limitations clock. Use scenario comparisons rather than assuming tolling periods add automatically.
  • Not stress-testing with alternate dates

    • Many tolling disputes reduce to date disputes (e.g., when concealment ended or when facts should have been discovered). Scenario testing in DocketMath is a practical way to gauge how sensitive the deadline is to those date choices.

Run the numbers

Here’s how DocketMath can help you see how tolling changes the outcome.

Scenario A: Minority tolling extends the deadline

Inputs (illustrative):

  • Accrual date: 2022-06-01
  • Claimant birthdate: 2008-09-15
  • Minority tolling ends: when claimant reaches the age threshold in C.R.S. § 13-81-101
  • No fraudulent concealment modeled

What changes:

  • Baseline deadline = “accrual + limitations period”
  • Adjusted deadline = “baseline deadline + paused time while minority tolling applies”

Use DocketMath to:

  • confirm the baseline limitations deadline,
  • calculate the pause interval based on the modeled minority window,
  • compare adjusted vs. baseline.

Scenario B: Fraudulent concealment shifts the deadline

Inputs (illustrative):

  • Accrual date: 2022-01-01
  • Fraudulent conceal
