Employment Discrimination Deadlines: Your EEOC Filing Window

Employment discrimination claims come with some of the shortest deadlines in civil law, and missing one can end a strong case before anyone ever looks at the facts. Federal anti-discrimination laws generally require you to file a charge with the Equal Employment Opportunity Commission (EEOC) before you can sue — and the window for filing that charge is measured in days, not years. This guide explains how the 180-day and 300-day deadlines work, when the clock starts, and the mistakes that quietly run it out.

The core warning: you generally have 180 calendar days from the day the discrimination happened to file an EEOC charge, extended to 300 days where a state or local agency enforces a law prohibiting the same kind of discrimination. Holidays and weekends count, an internal HR complaint does not stop the clock, and waiting to “see how things go” is the single most common way workers lose otherwise valid claims. If you think discrimination happened, check your deadline now — not after the next performance review.

The 180/300-day framework

The general federal rule is 180 calendar days from the date of the discriminatory act. That period extends to 300 days when a state or local fair-employment agency enforces a law that prohibits discrimination on the same basis — which is the situation in much of the country, since most states have their own anti-discrimination agencies. But the extension is not automatic or universal: it depends on where you work, what kind of discrimination is involved, and whether the local law actually covers your claim. Age discrimination claims follow slightly different extension rules. The safe operating assumption is the shorter one — treat 180 days as your deadline until the EEOC or a lawyer confirms you have 300. The EEOC’s own time-limits page, linked below, is the authoritative starting point.

The laws behind the deadline

The charge-filing requirement comes from the major federal employment discrimination laws, which are worth knowing at a high level:

• Title VII of the Civil Rights Act prohibits employment discrimination based on race, color, religion, sex, and national origin.
• The Americans with Disabilities Act (ADA) prohibits discrimination against qualified workers with disabilities and requires employers to provide reasonable accommodations absent undue hardship.
• The Age Discrimination in Employment Act (ADEA) protects workers age 40 and over.

All of these also prohibit retaliation — punishing someone for complaining about discrimination, filing a charge, or participating in an investigation. For most claims under these laws, an EEOC charge is a required first step before a lawsuit. One notable exception: Equal Pay Act claims can go straight to court without an EEOC charge, on their own separate time limits. Many states have parallel laws with their own agencies, deadlines, and sometimes broader coverage.

When the clock starts

The deadline runs from the day the discriminatory act took place — and pinning down that day matters more than people expect:

• A firing, demotion, or refusal to hire starts the clock on the day it happens, usually the day you are told, not your last day of work or the day the paperwork processes.
• Separate acts get separate clocks. A discriminatory write-up in March and a discriminatory termination in August are distinct events, each with its own filing window. An old act does not extend the deadline for a new one, and a new act does not revive an expired one.
• Ongoing harassment is treated differently. A hostile work environment is typically built from many incidents over time, and timing rules for it are more forgiving — but only within limits, and only for genuinely connected conduct. Do not rely on this; file early.

When in doubt, use the earliest plausible date as your starting point. A charge filed early is safe; a charge filed one day late may not be.

Why waiting on HR runs out the clock

The most common deadline mistake is procedural patience: reporting to HR, cooperating with an internal investigation, and waiting months for a resolution while the federal window quietly closes. Internal complaints matter — they create records and can be legally significant in harassment cases — but they are not charges, and no employer process pauses the EEOC deadline. The same goes for severance negotiations, union grievances, and verbal promises to “make it right.” You can pursue an internal complaint and an EEOC charge at the same time, and filing a charge does not require you to quit, sue, or go public. Treat the two tracks as independent, because legally they are.

How filing a charge works

A charge is a signed statement to the EEOC asserting that an employer discriminated and asking the agency to act. Filing is free and does not require a lawyer. You can start online through the EEOC’s public portal, by phone, by mail, or at an EEOC field office; the how-to-file page linked below walks through each route. Charges can also be filed with a state or local fair-employment agency, which typically cross-files with the EEOC so one filing protects both sets of rights.

After you file, the EEOC notifies the employer, and the case may move to mediation, investigation, or dismissal. Many paths end with a right-to-sue notice — a document that starts a new, separate, and short deadline for filing a lawsuit. If you receive one, act on it immediately.

Two situations follow different rules entirely. Federal employees and applicants have their own complaint process with much shorter initial deadlines — typically requiring contact with an agency EEO counselor within 45 days. And union members may have contractual grievance deadlines that run separately from everything above.

Retaliation has its own clock

If your employer punishes you for complaining — firing, demotion, cut hours, a sudden bad review, threats — that retaliation is a distinct violation with its own filing deadline, even if the underlying discrimination claim is shaky or stale. Workers sometimes have a stronger retaliation claim than discrimination claim. Document what happened before you complained and what changed after, with dates. The same instinct applies to pay-related complaints: retaliation for wage complaints is separately illegal, as our unpaid wages guide explains.

Protecting your claim while you decide

Whatever you ultimately do, do two things now. First, build a dated record: a timeline of events, the emails and messages involved, performance reviews, witness names, and copies of anything you may lose access to if your employment ends. Second, mark the deadline: count 180 days from the discriminatory act and put it on a calendar, treating anything later as a bonus you have not yet confirmed. Neither step commits you to filing. Both keep the choice in your hands instead of letting the calendar make it for you.

When to get help

Deadline questions are exactly the kind of problem to bring to a professional early, because the analysis is fact-specific and the cost of guessing wrong is total. Contact the EEOC directly — its intake process exists for this — or find an employment lawyer for a consultation; many offer free case reviews, and our guide to finding legal help explains where to look. If cost is a barrier, our legal aid basics guide covers free legal services and who qualifies for them. The pattern in discrimination cases is unforgiving but simple: the workers who preserve their options are the ones who checked the deadline early, wrote things down, and filed before they had to.
