Statute of Limitations for Sexual Harassment (state claims) in Colorado

Overview

In Colorado, the statute of limitations (timing rule) for state-law sexual harassment claims is driven primarily by whether the claim is treated as discrimination under the Colorado Anti-Discrimination Act (CADA) or as a common-law tort (like intentional infliction of emotional distress) or another state cause of action.

DocketMath’s statute-of-limitations calculator helps you translate dates (like the date you experienced the last alleged incident and the date you filed) into a practical “time window” for filing. This post focuses on Colorado state claims, not federal claims under Title VII or related statutes.

Limitation period

1) CADA (Colorado Anti-Discrimination Act) discrimination/harassment claims

For sexual harassment claims pursued under Colorado’s anti-discrimination law (CADA), the general rule is that a complainant must act within 300 days of the date of the alleged discriminatory act (commonly the last act in the harassment pattern, depending on how the facts are pleaded).

Practically, this “300-day” clock matters most when you’re filing through the Colorado Civil Rights Division (Division) process. If you miss that deadline, the claim may be time-barred.

How to think about the timeline

• Start point: typically the date of the discriminatory act you’re complaining about.
• Ending point: the date your complaint is filed within the agency process.
• Most commonly relevant incident: in ongoing harassment, your “last incident” often becomes the anchor date—especially when the conduct is treated as a continuing course of conduct.

2) Common-law tort theories (non-CADA state claims)

If you’re bringing a state claim that sounds more like a tort (rather than a statutory discrimination claim), Colorado generally applies different limitation periods depending on the cause of action. Common examples in harassment-related pleadings include:

• Intentional infliction of emotional distress
• Negligence-based theories (less common in harassment cases, but sometimes alleged)
• Breach of contract or retaliation theories pled in contract form (fact-dependent)

Because limitation periods for torts vary by category, DocketMath’s calculator becomes especially useful: you can choose the claim category and then input the relevant event date.

Key exceptions

Even when a general limitation period exists, certain doctrines can affect whether a claim is still timely.

1) Continuing violation concepts (fact-driven)

In harassment scenarios, Colorado courts may analyze whether the claim is based on a continuing series of discriminatory acts rather than a single isolated event. If the actionable conduct includes later incidents within the window, earlier acts may sometimes be considered as part of the broader course.

Practical effect on timing

• If harassment continues after an early incident, the “last act” may pull earlier conduct into the limitation analysis.
• If the conduct ended long before the filing date, the claim is more likely to be time-barred.

2) Accrual timing: when the “clock” starts

For CADA and for tort-type state claims, the statute of limitations generally starts when the claim accrues—often meaning when you knew or should have known of the injury/discriminatory conduct. The exact accrual trigger depends on claim type and the pleaded facts.

Practical checklist

• Did the last discriminatory act occur within the time window?
• Are you alleging discrete incidents with specific dates?
• Does the claim depend on harm that was not reasonably discoverable earlier?

3) Tolling (limited, and strongly dependent on facts)

Tolling can pause or extend the limitations period in certain circumstances (for example, some filing or administrative steps can affect timing analysis). Whether tolling applies in a particular harassment dispute can turn on:

• what you filed,
• when you filed,
• how the filing process interacts with limitation rules, and
• the claim’s legal category.

4) Administrative prerequisite vs. civil action timing

For CADA discrimination claims, the procedural path matters. If you file in the wrong forum or miss agency timing, the result may be dismissal on timeliness grounds even if you later file in court.

Statute citation

Colorado’s principal state statute for discrimination is the Colorado Anti-Discrimination Act (CADA), codified at Colo. Rev. Stat. §§ 24-34-401 to 24-34-802.

For limitation timing tied to filing with the agency, the key reference point for the 300-day rule is found in Colo. Rev. Stat. § 24-34-306 (procedures and deadlines for discrimination complaints).

For non-CADA tort-like claims, the limitation periods depend on the specific cause of action under Colorado statutes (for example, Colorado has distinct limitation periods for different categories of injuries and contract/debt claims). Because these vary, the calculator approach is usually the cleanest way to avoid mixing categories.

Use the calculator

DocketMath’s statute-of-limitations tool helps you compute the latest filing date based on the limitation period for the claim type.

Use the calculator at: **statute-of-limitations

Then input (at minimum) the following:

• Jurisdiction: Colorado (US-CO)
• Claim type: choose the category that matches your state claim framing

  • CADA / discrimination- or harassment-based state claim (typically tracks the 300-day rule)
  • Tort-style or other state claims (choose the closest category available)
• Event date: typically the date of the last alleged incident or the date the discriminatory act occurred
• Filing date (optional, for “am I late?”): date you filed the complaint or lawsuit

What outputs you’ll get
Depending on how the tool is configured, you’ll generally see:

• End of limitations window (latest date you can file)
• Time elapsed between event date and filing date
• Timeliness indicator (timely vs. potentially time-barred)

How outputs change when you change inputs Here are common scenarios:

• If you move the “event date” forward (because you’re able to prove a later incident):
  ✅ the latest filing date moves forward too, which can materially affect timeliness.
• If you use an earlier “event date” than the last alleged incident:
  ❌ the filing deadline gets earlier, increasing the risk a claim is out of time.
• If you switch claim type in the calculator:
  ⏱ limitation periods may change, and with it the timeliness result. CADA-based discrimination timing generally differs from tort-type timing.

Quick examples (date math, not legal advice)
Assume a CADA-style limitation period of 300 days:

• Event date: January 10, 2025
• Latest filing window: 300 days later (compute via DocketMath for the exact calendar date accounting for leap years and day-count rules)

Then:

• Filing on October 15, 2025 might still be within the window, while
• Filing on November 1, 2025 might fall outside it (again, verify with the calculator’s exact output).

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.
