How to File an EEOC Complaint Against Your Employer: Step-by-Step

Confirm You Have a Claim the EEOC Covers

The EEOC handles complaints involving discrimination or harassment based on race, color, sex (including pregnancy and sexual orientation), religion, national origin, age (40 and older), disability, and genetic information, along with retaliation for reporting any of these. If your situation doesn't fit one of these protected categories, the EEOC may not be the right venue, though California's Civil Rights Department covers some additional categories under state law.

If you're not sure which agency is the right fit, it's usually not a mistake that costs you anything, since California and the EEOC have a work-sharing agreement that generally allows a charge filed with one agency to be treated as filed with both. Starting the process is more important than picking the theoretically perfect agency on your first try.

Know Your Deadline

You generally have 180 days from the date of the discriminatory act to file a charge, but that window extends to 300 days in states like California that have their own fair employment practices agency. Missing this deadline can permanently bar your claim through the statute of limitations, so don't wait to see how things play out before filing.

If the discrimination you experienced happened more than once, the clock generally runs from the most recent incident, though older incidents can sometimes still support your case as background evidence even if they'd be too old to file on individually. When in doubt about your specific deadline, treat sooner as always safer than later.

Example

Your last day of unlawful treatment was March 1. In California, your EEOC filing deadline is roughly December 26 of that same year, not the following spring.

Gather Your Documentation First

Before you file, pull together anything relevant: performance reviews, emails, text messages, witness names, your employee handbook, and a written timeline of what happened and when. You don't need a polished legal argument to file, but specific dates and details make your charge stronger from the start.

It helps to organize what you have chronologically rather than by type of document, since a clear timeline is often what an investigator finds most useful. If you're missing something, like an old email you deleted, note that it existed and roughly when, since your own recollection still carries weight even without the original file.

Don't wait until you feel like you have a complete file to start the process, either. Gathering documentation and filing your charge can happen in parallel, and starting the clock on your charge sooner rather than later protects you from deadline problems even if your file is still coming together.

Choose How You'll File

You can start the process through the EEOC's online portal, by phone, by mail, or in person at your nearest EEOC office. Most people find the online intake system, called the Public Portal, the fastest way to begin, since it lets you submit an inquiry and schedule an interview with an EEOC staff member who helps finalize your formal charge.

During that intake interview, the staff member will ask clarifying questions to make sure your charge accurately reflects what happened and fits within the categories the EEOC can act on. It's worth treating this conversation seriously and coming prepared with your documentation rather than relying entirely on memory.

What to Include in Your Charge

Your charge should identify your employer, describe what happened in specific, factual terms, name the protected characteristic involved, and lay out a rough timeline. Avoid vague language like “they treated me unfairly.” A stronger charge describes specific incidents: who said what, when it happened, and how it differed from how others were treated.

It's also worth naming specific comparators when you can, coworkers outside your protected category who were treated more favorably in a similar situation. A charge that says 'I was written up for being late, but my coworker who isn't disabled was late just as often and never disciplined' gives an investigator something concrete to look into.

You can amend a charge after filing if you remember additional details or if something new happens, so don't feel like your initial filing has to capture absolutely everything. Getting the core facts and timeline down accurately matters more than making the first draft perfect.

Example

Instead of writing "my boss was biased against me," a stronger charge says "On March 3, my supervisor told me directly that he preferred not to promote women into lead roles, then promoted a less senior male coworker on March 10."

What Happens Immediately After You File

Once your charge is filed, the EEOC will notify your employer, typically within about 10 days. From there, your employer may be given the opportunity to respond, and in some cases the EEOC offers mediation before a full investigation begins. It's illegal for your employer to retaliate against you simply because they were notified, which we cover in more detail in our guide on getting fired after filing an EEOC complaint.

This is often the point where workplace dynamics shift, sometimes subtly, sometimes not. It's worth paying closer attention than usual to how you're treated in the weeks immediately following notification, since that period tends to generate the clearest evidence if retaliation is going to happen at all.

Mistakes That Weaken a Charge

The most common mistakes are waiting too long to file, leaving out specific dates and details, and failing to update the EEOC if retaliation happens after the original charge. Another frequent issue is assuming a single dramatic incident is required, when in reality a pattern of smaller incidents can build just as strong a case as one obvious event.

We also see people undersell their own charge out of politeness, softening what happened because it feels uncomfortable to describe a coworker or supervisor's conduct plainly. An investigator can only act on what's actually written down, so it's worth describing events accurately rather than diplomatically.

What to Do Next

If you're unsure whether your situation qualifies or how to describe it effectively, having an employment attorney review the details before you file can make a meaningful difference in how your charge is written. Once you've filed, it's worth understanding what happens at each stage of the EEOC process so you know what to expect next.

It's also worth thinking ahead about retaliation before you ever file. Knowing what protection you have going in, covered in our companion guide on being fired after filing an EEOC complaint, can help you recognize a retaliatory response quickly if one happens rather than second-guessing yourself.
