EEOC Deadlines: 180 Days vs. 300 Days Explained: key questions
A visual route through this article's first three topics. Read the sections below for details and exceptions.
Which Workers Use the 180-Day or 300-Day Rules?
The 180-day and possible 300-day rules generally concern charges against private employers and state or local government employers under laws enforced by the EEOC.
The 180-Day Rule
The default federal deadline is generally 180 calendar days from the alleged discrimination.
When 300 Days May Apply
The EEOC says the 180-day deadline may extend to 300 calendar days when a state or local agency enforces a law that prohibits employment discrimination on the same basis.
Which Workers Use the 180-Day or 300-Day Rules?
The 180-day and possible 300-day rules generally concern charges against private employers and state or local government employers under laws enforced by the EEOC. Most Title VII, ADA, ADEA, GINA, and Pregnant Workers Fairness Act claims require a timely charge before a federal lawsuit. Federal employees and applicants use a different agency EEO process, and Equal Pay Act claims follow different filing rules.
The 180-Day Rule
The default federal deadline is generally 180 calendar days from the alleged discrimination. For a discrete decision such as termination, refusal to hire, demotion, or denial of promotion, the filing period generally runs from that act. Later effects of an earlier decision do not necessarily restart the clock, so record the decision date, notice date, and effective date instead of relying on a rough month or pay period.
When 300 Days May Apply
The EEOC says the 180-day deadline may extend to 300 calendar days when a state or local agency enforces a law that prohibits employment discrimination on the same basis. Age-discrimination charges have a narrower rule: the 300-day extension applies only when a state law prohibits age discrimination in employment and a state agency or authority enforces that law. Because the longer window depends on the claim, location, and enforcing agency, workers should not assume 300 days applies without checking.
How to Check Which Filing Window May Apply
Start with where the alleged discrimination occurred and the basis of the charge. The possible 300-day window depends on whether a state or local agency enforces a law prohibiting discrimination on that same basis. A Fair Employment Practices Agency may dual-file a charge with the EEOC when federal law applies, but state and local filing limits can differ. Check both routes promptly instead of assuming the longest period controls.
Discrete Acts and Hostile Environment Claims Differ
The Supreme Court distinguishes discrete employment acts from a hostile work environment. Each discrete act generally needs to fall within the filing period. A hostile-environment claim may include related conduct outside the period when at least one act contributing to the same hostile environment occurred within the filing window. Whether incidents form one actionable environment is fact-specific, so preserve every incident date and do not treat an old event as automatically timely.
Compensation Discrimination Has a Separate Timing Rule
The Lilly Ledbetter Fair Pay Act provides that covered compensation discrimination can occur when a discriminatory compensation decision or practice is adopted, when a worker becomes subject to it, or when the worker is affected by its application, including certain paychecks or benefit payments. That rule does not turn every old employment decision into a timely pay claim. Identify the challenged compensation practice and each affected payment.
Federal Employees Usually Start With a 45-Day Contact
Federal employees and applicants generally must contact an EEO Counselor at the employing or hiring agency within 45 days of the discriminatory event. For a personnel action such as a demotion or firing, EEOC guidance generally measures from the effective date. The federal-sector route has later deadlines too, including a 15-day period to file a formal complaint after receiving the counselor's notice.
The Equal Pay Act and Other Claims Use Different Routes
The Equal Pay Act does not require an EEOC charge before a lawsuit, although a related Title VII compensation claim may still require a timely charge. Wage claims, OSHA retaliation, FMLA, union, and whistleblower claims can use different agencies and much shorter limits. Identify every plausible route early and protect the shortest deadline rather than treating an EEOC inquiry as filing every possible claim.
Do Not Wait for Another Process to Finish
EEOC guidance says charge-filing limits generally are not extended while a worker pursues an internal grievance, union grievance, arbitration, mediation, or another forum. Starting an online inquiry also is not necessarily the same as filing a signed charge. Confirm what was submitted, when it was received, and whether a state or local agency will dual-file it.
Protect the Earliest Plausible Deadline
Create a dated timeline for each decision, incident, report, paycheck, and notice. Save the evidence tied to each date, identify the employer and work location, and get a free consult before filing. The EEOC says its Public Portal provides special directions for quickly providing information and filing when 60 days or fewer remain. Deadline questions can turn on the claim, employer, jurisdiction, and event, and the wording of a charge can affect which allegations are preserved later.
