Statute of Limitations on EEOC Claims: 180, 300, and 45 Days

The statute of limitations on EEOC claims is generally 180 calendar days from the date of the discriminatory act, extended to 300 days if a state or local anti-discrimination agency covers the workplace. Federal employees operate on a much tighter timeline: 45 days to contact an EEO counselor at their own agency. And once the EEOC issues a Notice of Right to Sue, you have 90 days to get into court. Miss any of these, and the claim usually dies.

The 180-Day and 300-Day Charge Deadlines

For private-sector workers and state or local government employees, the default federal deadline is 180 calendar days from the date the discrimination occurred.¹ This baseline covers claims under Title VII of the Civil Rights Act, the Americans with Disabilities Act, and the Genetic Information Nondiscrimination Act.

The deadline stretches to 300 calendar days when the state or locality where the discrimination happened has its own anti-discrimination law and an agency, called a Fair Employment Practices Agency, that enforces it.¹ Most states have one, so 300 days applies to the majority of workers. Because of work-sharing agreements, filing with either the state agency or the EEOC automatically cross-files with the other.²

When the Filing Clock Starts

For a single discriminatory event, such as a firing, demotion, or denial of a promotion, the clock starts the day it happens. Each discrete act carries its own deadline. If your employer demoted you in January and fired you in August, the demotion claim runs from January and the termination claim runs from August. Filing a timely charge about the firing will not revive the demotion claim if that earlier deadline has already lapsed.¹

Constructive discharge follows a slightly different rule. If working conditions became so intolerable that you had no real choice but to resign, the clock starts when you give notice of the resignation, not your last day on the job. The Supreme Court set this rule in Green v. Brennan, treating the resignation itself as part of the discriminatory act.³

Hostile Work Environment Claims

Hostile work environment claims are treated as a continuing violation rather than a single event. Under National Railroad Passenger Corp. v. Morgan, the claim is timely as long as at least one act contributing to the hostile environment falls within the 180- or 300-day window. When that condition is met, the entire pattern of harassment can be considered, including incidents from years earlier.⁴ One recent incident keeps the whole claim alive. Standalone acts like a firing do not get that treatment.

Federal Employees: 45 Days, Not 180

Federal workers follow a completely separate track with a much shorter initial window. Instead of filing a charge with the EEOC, a federal employee must contact an EEO counselor at their own agency within 45 calendar days of the discriminatory act.⁵ The step is mandatory.

The counselor typically offers a choice between informal counseling and alternative dispute resolution such as mediation. If nothing resolves the dispute, the counselor issues a Notice of Right to File a Formal Complaint. The employee then has just 15 calendar days from receiving that notice to file the formal written complaint with the agency’s EEO office.⁵ Missing that 15-day window gives the agency grounds to dismiss the complaint outright.⁶

The 45-day contact deadline is where most federal claims die. If you’re a federal employee and something has just happened, contact the agency’s EEO office right away, even before you have decided whether to pursue a formal complaint.

Pay Discrimination Has Its Own Clock

The Lilly Ledbetter Fair Pay Act

Under the Lilly Ledbetter Fair Pay Act of 2009, the 180- or 300-day filing deadline resets with every paycheck that reflects a discriminatory pay decision. Each affected paycheck counts as a new violation.⁷ Even if the original pay decision was made years ago, a charge is still timely as long as a paycheck reflecting that decision landed within the filing window. The rule applies to claims under Title VII and the Age Discrimination in Employment Act.

The Equal Pay Act

The Equal Pay Act, which covers sex-based wage disparities, skips the EEOC charge process entirely. You can go straight to court. The deadline to file an EPA lawsuit is two years from the most recent discriminatory paycheck, or three years if the employer’s violation was willful.⁸ Filing an EPA charge with the EEOC is also an option, and the same time limits apply.⁹

Age Discrimination Claims

Age Discrimination in Employment Act claims share the same 180- or 300-day charge deadline, but the path to a lawsuit differs. Unlike Title VII claims, you don’t need a Notice of Right to Sue. You can file a federal lawsuit 60 days after filing the EEOC charge.¹⁰ That gives ADEA claimants a faster route into court if the investigation is slow.

The 90-Day Deadline to File a Lawsuit

For Title VII, ADA, and GINA claims, the EEOC charge is a prerequisite to suing, not the lawsuit itself. After the EEOC investigates, it issues a Notice of Right to Sue. You can also request that notice yourself once 180 days have passed since you filed the charge.¹⁰

Once the Right to Sue notice arrives, you have exactly 90 days to file a lawsuit in federal court.¹¹ Courts enforce this strictly. The period runs from the date you received the notice, not the date the EEOC mailed it, though courts will sometimes presume receipt a few days after mailing when the exact date is disputed.

When Deadlines Can Be Extended

The EEOC deadlines are firm, but not absolute. Courts recognize a narrow set of situations where the clock can be paused under equitable tolling or equitable estoppel.

Equitable Tolling

Equitable tolling can extend the deadline when circumstances beyond your control prevented timely filing. The EEOC recognizes four main grounds:¹²

You had no reason to suspect discrimination. The period is tolled until you discover, or reasonably should have discovered, that discrimination occurred.
Severe mental incapacity prevented you from pursuing legal remedies during the filing period.
The EEOC or a state agency gave you incorrect information about the deadline or mishandled your charge.
You filed a timely complaint in the wrong forum while diligently trying to assert your rights.

Equitable Estoppel

Equitable estoppel applies when the employer’s own conduct caused the delay: concealing facts that would have supported a charge, assuring you the problem would be handled internally, or threatening retaliation for filing.¹² Tolling looks at your circumstances; estoppel looks at the employer’s behavior. Neither is a routine escape hatch. Courts expect you to file as soon as the obstacle is gone.

Retaliation Starts Its Own Clock

Federal law prohibits punishing an employee for filing a charge, taking part in an investigation, or opposing practices believed to be discriminatory.¹³ If the employer fires, demotes, or otherwise takes adverse action against you because of a charge, that retaliation is an independent violation with its own 180- or 300-day filing deadline. Retaliation charges are among the most common the EEOC handles, and they can succeed even when the underlying discrimination claim does not.
