Statute of Limitations for State Employment Discrimination in Colorado

Overview

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

Colorado generally sets a 300-day deadline to file a state employment discrimination complaint with the Colorado Civil Rights Division (CCRD) under the Colorado Anti-Discrimination Act (CADA). That 300-day clock usually runs from the date of the alleged discriminatory act—often including discrete decisions such as pay decisions and termination decisions.

DocketMath’s statute-of-limitations calculator helps you model timing quickly for the most common CCRD administrative filing route. This page explains the controlling limitation period, key exceptions and timing wrinkles that can change the result, and how to think about “trigger dates” (for example, whether you should use the date you were notified versus the date it became effective).

Limitation period

Colorado’s administrative limitation period for most employment discrimination claims under CADA is 300 days. Practically, you should plan to submit your CCRD charge within 300 days of the discriminatory act you are challenging.

What starts the clock (common trigger points)

The “trigger” is typically the date of the act you claim was discriminatory. Common examples include:

• Termination: the day you were discharged or the day you received notice of discharge (depending on the facts).
• Failure to hire / refusal to promote: the day the decision was communicated.
• Disciplinary action: the day the discipline decision was imposed or communicated.
• Pay discrimination: the date of the pay decision or the date the paycheck reflects the discriminatory decision.

How the 300-day window plays out (practical timeline)

Because the deadline is day-based (not “three months” or “ten months”), using a calculator is often more reliable than counting calendar months by hand. A simplified visualization:

What does “administrative filing” mean here?

For CCRD timing, the key action is typically the filing of the charge/complaint with the CCRD. If you are still deciding whether to file, you generally want your deadline information early—because missing the limitation period can prevent the agency from proceeding on that claim.

Key exceptions

The 300-day period is the baseline, but several timing issues can affect whether a claim is timely.

1) Continuing violations and repeated discriminatory conduct

A common timing question is whether earlier acts can be treated as part of a broader, ongoing pattern—particularly where there are repeated denials, repeated discriminatory pay decisions, or other recurrent conduct.

In general, courts and agencies often distinguish between:

• Discrete acts (for example, a specific termination decision), where the clock runs from the discrete event; and
• Ongoing conduct that continues over time, where later acts may sometimes help you argue that related earlier matters are part of a continuing course.

DocketMath can’t decide how Colorado law characterizes your specific pattern. However, you can use the tool to model latest possible deadlines based on your most recent discriminatory event (and also compare scenarios using earlier events).

2) Identity of the “decision” date vs. the “impact” date

Another timing wrinkle is that the relevant date may be tied to the decision or communication, not necessarily when you later experienced consequences.

Examples:

• You learn on one date you were not being promoted; the role or responsibilities change later.
• You receive termination notice effective immediately, but payroll and system processing changes occur over time.

To reduce deadline surprises, identify the most defensible trigger date from your timeline and then calculate based on that date.

3) Tolling (pauses) and procedural complications

Sometimes timing changes due to tolling (pauses) or procedural requirements. Tolling is highly fact-dependent and can depend on issues such as:

• Whether a prior filing was made in a way that preserved claims;
• Whether a dismissed claim was refiled within a specific framework; and
• Whether administrative prerequisites were satisfied on time.

Because tolling outcomes depend heavily on the procedural history, treat tolling as a “verify before relying” topic. DocketMath can calculate baseline deadlines, but it can’t automatically incorporate complex procedural histories.

Statute citation

Colorado’s 300-day administrative limitation period for many employment discrimination complaints under CADA is set out at:

• C.R.S. § 24-34-402(1)(a): establishes the timeline for filing with the Colorado Civil Rights Division, including the 300-day requirement for many employment discrimination charges.

Depending on your allegations (for example, disability, sex, race, retaliation, or age), other provisions within CADA may also be relevant to the scope of the claim. The key takeaway for this calculator page is that the 300-day administrative deadline is a primary timing rule for CCRD filings.

Use the calculator

DocketMath’s statute-of-limitations calculator helps you convert a known event date into a filing deadline using the Colorado 300-day rule.

Inputs to use

In general, you’ll enter:

• Event date (the date of the alleged discriminatory act or the best-supported trigger date)
• Jurisdiction: **Colorado (US-CO)
• Claim type / filing route (if prompted—choose the administrative CCRD route if that’s your plan)

How outputs change when the event date changes

Because the calculation is day-based, even a small shift in the “event date” can change the filing deadline by days (and sometimes move it into a different calendar month). For example:

• Event date: May 10 → 300 days later: Mar 6 (following year, depending on leap-year timing)
• Event date: May 25 → 300 days later: Mar 21 (same general time, different calendar date)

That’s why the most important input is picking the most defensible trigger date—often the date the decision was communicated or the discriminatory act occurred.

Recommended workflow (practical and fast)

1. Create a mini timeline for each alleged action (notice date, effective date, paycheck date).
2. Pick the trigger date that best matches the theory of your claim.
3. Run DocketMath for each discrete act if you have multiple events.
4. Use the earliest deadline that applies to the claims you care about most, and plan to file comfortably earlier.
