How to File an EEOC Complaint in Massachusetts: Step-by-Step Guide
Last reviewed: July 2026
Quick Answer
In Massachusetts, you have 300 days from the date of discrimination to file an EEOC charge (extended because Massachusetts is a deferral state). File with the Massachusetts Commission Against Discrimination (MCAD) first, and your complaint will be automatically cross-filed with the EEOC under their worksharing agreement. You can file online at EEOC.gov, by mail to the Boston EEOC office, or by phone at 1-800-669-4000. Massachusetts law under Chapter 151B provides the same protected classes as federal law but also adds additional protections.

Federal Law: The Baseline
Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e, prohibits employment discrimination based on race, color, religion, sex, or national origin. The Age Discrimination in Employment Act (ADEA), 29 U.S.C. § 621, protects workers 40 and older. The Americans with Disabilities Act (ADA), 42 U.S.C. § 12101, protects qualified employees with disabilities. Title I of the ADA applies to employers with 15 or more employees. Title VII applies to employers with 15 or more employees working for 20 or more calendar weeks in the current or preceding calendar year.
The Genetic Information Nondiscrimination Act (GINA), 42 U.S.C. § 2000ff, prohibits discrimination based on genetic information. Federal law provides for remedies including back pay, front pay, compensatory damages for emotional distress, punitive damages, attorney's fees, and court costs. The Equal Employment Opportunity Commission (EEOC) enforces these federal statutes and investigates complaints filed under them.
In Massachusetts, which is a "deferral state," you must file with the state agency (MCAD) first, or file with both the EEOC and MCAD simultaneously. The federal deadline to file an EEOC charge is 300 days from the discrimination date in deferral states (versus 180 days in non-deferral states). Charges are automatically cross-filed between MCAD and EEOC through a worksharing agreement.
Massachusetts Law: What's Different
Massachusetts General Laws Chapter 151B creates a comprehensive state anti-discrimination statute that is often stronger than federal law. The Massachusetts Commission Against Discrimination (MCAD) is the state agency responsible for investigating discrimination complaints. Massachusetts law covers the same protected classes as federal law (race, color, religion, sex, national origin, age 40+, disability, genetic information) but also adds additional protections: sexual orientation, gender identity, marital status, and military status are explicitly protected under Chapter 151B.
Massachusetts law applies to employers with six or more employees, while federal Title VII requires 15 or more employees. This means smaller employers in Massachusetts are covered under state law but not federal law. Additionally, Massachusetts recognizes broader definitions of harassment and hostile work environments compared to federal precedent. The state also prohibits discrimination in public accommodations and housing, providing broader remedies than federal law alone.
Under Massachusetts law, damages available include back pay, front pay, compensatory damages for emotional distress and humiliation, punitive damages in cases of willful violation, attorney's fees, costs, and prejudgment interest. Massachusetts courts have interpreted Chapter 151B to provide stronger protections for sexual harassment and retaliation claims than federal Title VII standards. The state law also imposes a higher bar for employers to justify certain employment decisions, shifting more burden to the employer to prove legitimate nondiscriminatory reasons.
When you file a charge with MCAD, it is automatically cross-filed with the EEOC through their worksharing agreement. MCAD has jurisdiction to investigate under both state law (Chapter 151B) and federal law (Title VII, ADA, ADEA, GINA). This dual jurisdiction means a single filing triggers investigation under both state and federal standards, which can result in broader findings and stronger remedies under state law.
Key Numbers & Thresholds
You have 300 days to file an EEOC charge in Massachusetts (deferral state deadline is 300 days, compared to 180 days in non-deferral states). Massachusetts law covers employers with 6 or more employees (federal Title VII requires 15 or more). You can request a right-to-sue letter after 180 days of filing if you want to proceed to federal court without waiting for investigation completion. MCAD typically investigates for up to 210 days before determining reasonable cause or dismissing the charge.
Exceptions & Special Cases
Massachusetts law contains important exceptions and limitations that affect who can file and what remedies are available. The "employment relationship" requirement means independent contractors and truly volunteer workers are not covered, though Massachusetts courts interpret this broadly to include workers misclassified as independent contractors. Applicants who were never hired are generally not protected under anti-discrimination law, though retaliation for job application inquiries may be actionable.
Federal law and Massachusetts law both exempt bona fide occupational qualifications (BFOQs), where an employer can prove that a protected characteristic is genuinely necessary for the job. For example, a theater may cast actors based on age or gender if artistically essential. Both laws also exempt seniority systems that were adopted for legitimate nondiscriminatory reasons, even if they perpetuate prior discrimination.
At-will employment generally permits employers to terminate for any reason that is not illegal. Massachusetts is an at-will employment state, but it recognizes exceptions where termination based on protected status, retaliation for protected activity, or violation of public policy is prohibited. However, if an employee is terminated for a non-discriminatory reason, the employer can still do so under at-will doctrine.
Union employees and those covered by collective bargaining agreements may be limited in their remedies. If a union has filed a grievance on the employee's behalf, the EEOC may defer to the arbitration process. Additionally, certain government employees may have different filing requirements or remedies under federal statute. Charges alleging discrimination by federal employers must follow specific procedures under 42 U.S.C. § 2000e-16.
What to Do If Your Rights Are Violated
Step 1: Document Everything — Keep detailed records of all discriminatory incidents, dates, times, locations, what was said, who witnessed it, and any company responses. Save all relevant emails, text messages, performance reviews, and disciplinary notices. Write down details immediately after incidents occur while memory is fresh. Document your job duties, achievements, and any evidence you performed better than non-protected-class employees. Photograph any relevant physical evidence if safe to do so.
Step 2: Report Internally — File a formal written complaint with your employer's human resources department or management. Send the complaint via email so you have a time-stamped record. Keep copies of your internal complaint and any response from the company. Note that internal complaint procedures are not required to file with EEOC, but internal reporting can strengthen your case by showing the employer had notice and opportunity to correct the problem. If your employer has a clear anti-retaliation policy in the employee handbook, reference it in your complaint.
Step 3: File Your EEOC Charge — You have 300 days from the discrimination date to file. File with MCAD (Massachusetts Commission Against Discrimination) or simultaneously with both MCAD and EEOC. You can file online at www.eeoc.gov (use the online questionnaire and submit), by mail to EEOC Boston Area Office, 15 New England Executive Park, Suite 111, Burlington, MA 01803, by phone at 1-800-669-4000, or in person at the Boston office. You will need: your name, contact information, employer name and location, dates of employment, detailed description of what happened, protected characteristic involved, names of witnesses, and copies of supporting documents. Filing is free and you do not need an attorney to file.
Step 4: Investigation Process — After filing, MCAD and EEOC will send a charge acceptance letter and case number. The employer will receive notification and have an opportunity to respond. MCAD typically investigates within 210 days but can extend for complex cases. The investigator will contact you, your employer, and witnesses. You will likely be asked to provide additional statements and documents. The investigator may request that you and the employer participate in mediation or settlement discussions. After investigation, MCAD will issue a "reasonable cause" determination (meaning evidence supports your claim) or dismiss the charge. If dismissed, you can request a right-to-sue letter from EEOC to file in federal court.
Step 5: Consult an Attorney — Consider consulting an employment attorney once you have filed or if you anticipate filing. An attorney can help you understand your rights, prepare your charge filing, gather evidence, respond to discovery requests, and negotiate settlements. Many employment attorneys work on contingency (no upfront cost). If you win, the employer typically pays your attorney's fees and court costs. Contact the Massachusetts Bar Association Lawyer Referral Service or search for EEOC employment discrimination attorneys in your area.

Frequently Asked Questions
Do I have to file with MCAD or can I file directly with the EEOC in Massachusetts?
Massachusetts is a "deferral state," which means the EEOC requires you to file with the state agency (MCAD) first or file with both simultaneously. If you file only with MCAD, your charge is automatically cross-filed with the EEOC under their worksharing agreement, so you do not need to separately file with the EEOC. However, you can file with both at the same time if you want to do so. The advantage of filing with MCAD is that you gain the benefit of Massachusetts state law protections, which cover smaller employers (6+ employees) and provide additional protected classes like sexual orientation and gender identity. Filing with MCAD does not prevent you from later pursuing federal claims; both agencies investigate the same charge.
My employer has only 8 employees. Can I still file an EEOC complaint?
Yes, you can file under Massachusetts state law through MCAD because Massachusetts law covers employers with 6 or more employees. The federal EEOC under Title VII only covers employers with 15 or more employees, but when you file with MCAD, you automatically get the benefit of state law investigation and remedies. When your charge is cross-filed with the EEOC, the federal investigation may not proceed if your employer is too small, but MCAD will investigate under state law. This is an important reason to file with MCAD: it allows you to access protections that federal law does not provide for small employers.
What should I do if my employer retaliates against me for filing an EEOC complaint?
Retaliation is illegal under both federal law (Title VII, ADA, ADEA, GINA) and Massachusetts state law (Chapter 151B). If you experience retaliation after filing an EEOC charge or participating in an investigation, you can file an additional retaliation charge with MCAD/EEOC. Retaliation includes termination, demotion, reduced hours, negative evaluations, exclusion from meetings, or any adverse employment action taken because you filed a complaint or participated in an investigation. Document the retaliation immediately with dates, times, and witnesses. Notify your employer in writing (preferably via email) that you believe you are being retaliated against and reference your earlier discrimination complaint. Contact your EEOC investigator if one has been assigned; they can help document the retaliation as part of your original investigation.
How long does the EEOC investigation take and when can I file a lawsuit?
MCAD typically completes its investigation within 210 days, though complex cases may take longer. After investigation, MCAD issues a reasonable cause determination or dismissal letter. If MCAD finds reasonable cause, it will attempt to conciliate (settle) the dispute with the employer. If conciliation fails, you have the right to sue in civil court. If MCAD dismisses your charge or if you want to proceed without waiting for completion, you can request a "right-to-sue" letter from the EEOC after 180 days of filing. Once you have a right-to-sue letter, you have 90 days to file a lawsuit in federal court or state court. You do not have to wait for the investigation to conclude to pursue a lawsuit; requesting a right-to-sue letter allows you to proceed immediately.
What additional protections does Massachusetts law provide that federal law does not?
Massachusetts General Laws Chapter 151B provides several protections beyond federal Title VII: (1) it covers employers with 6 or more employees instead of 15, (2) it explicitly protects sexual orientation and gender identity, which federal law does not, (3) it protects marital status, (4) it protects military status, and (5) Massachusetts courts have developed stronger precedent for sexual harassment and hostile work environment claims. Massachusetts law also provides broader definitions of "public accommodations" and covers discrimination in housing and credit. Additionally, Massachusetts recognizes a "public policy" exception to at-will employment, allowing wrongful termination claims for firing someone for exercising legal rights like jury duty, voting, or filing a workers' compensation claim. These state-law protections mean that even if your federal claim fails due to employer size or lack of federal coverage, you may still have a strong claim under state law.
