The 180 vs. 300-Day Deadline — Don't Get This Wrong
The single most common reason strong cases die: the worker filed three days too late. Here's how the deadline actually works.
The EEOC filing deadline is jurisdictional in effect — miss it and the underlying claim is gone, no matter how strong. This deep dive explains which deadline applies to you, how 'continuing violations' work, and which acts restart the clock.
180 days, unless you're in a 'deferral' state
The baseline federal deadline to file an EEOC charge is 180 calendar days from the discriminatory act. In states with a state or local FEP agency that prohibits the same conduct (most states), the deadline extends to 300 days. Knowing which bucket your state is in is step one — don't assume.
When the clock starts
The clock starts on the date the adverse action occurs, not the date you learn about its full consequences. For a termination, it's the date you're told you're fired — not your last day of work, not the date you exhaust severance. Misreading this trigger is the single most common filing error.
The continuing violation doctrine
Hostile work environment claims can reach back beyond the 180/300-day window if at least one contributing act falls inside it (National Railroad Passenger Corp. v. Morgan). Discrete acts — firings, demotions, failures to promote — do not get this benefit; each one needs its own timely filing.
Equitable tolling — rare, but real
Courts may toll the deadline where the employer affirmatively misled the worker, where extraordinary circumstances genuinely prevented filing, or where the EEOC itself misdirected the worker. Tolling is the exception, not a plan. If you need to rely on it, you have already lost the easy version of your case.
Pay discrimination and the Ledbetter Act
The Lilly Ledbetter Fair Pay Act resets the clock with each paycheck affected by a discriminatory pay decision. Pay-equity claims can therefore be filed long after the original decision — but only the paychecks within the limitations window are recoverable as back pay (with carry-forward to two years before filing).
Practical checklist
Identify the precise date of the adverse act. Confirm whether your state is a deferral state. Mark Day 150 and Day 270 on your calendar as filing-prep deadlines. Use the EEOC Public Portal to start the inquiry — the inquiry preserves a record even before the formal charge is drafted.
Key takeaways
- Most states: 300 days. A handful: 180. Confirm yours before doing anything else.
- The clock starts when the adverse act occurs, not when its consequences finish playing out.
- Hostile environment claims can reach back; discrete acts each need their own timely filing.
- Pay claims reset every paycheck under the Ledbetter Act.
- Start the EEOC inquiry well before the deadline — the inquiry itself preserves a record.
