A C-3 form is the official workers’ compensation claim form used in New York to notify the Workers’ Compensation Board that you were injured on the job. Filing a C-3 is how you formally open your workers’ comp case with the Board, and you must file it within two years of your injury date or risk losing your right to benefits entirely. Without a filed C-3, the Board has no record of your claim, and you cannot receive wage replacement benefits even if your employer and their insurer already know about your injury.

Many injured workers in New York assume that reporting the injury to their employer is enough to start the claims process. It isn’t. Notifying your employer and filing a C-3 with the Workers’ Compensation Board are two separate requirements, and both must be completed. Our NYC workers’ comp lawyers at Katz, Leidman, Freund & Herman help injured workers throughout New York City make sure every deadline is met and every required form is filed correctly from the start.
Who Needs to File a C-3 Form in New York?
Any worker in New York who suffers a job-related injury or occupational disease and wants to receive workers’ compensation benefits must file a C-3 form. This applies to full-time employees, part-time employees, and in some cases workers who were misclassified as independent contractors but functioned as employees. If you were hurt at work or developed a condition caused by your job duties, filing a C-3 is a required step in the claims process regardless of the industry you work in or the size of your employer.
There is one limited exception. If your employer’s workers’ comp insurer begins paying your medical bills and wage replacement voluntarily and without dispute, you may not need to file a C-3 immediately. However, relying on that exception is risky. If the insurer later disputes your claim or stops paying, having a C-3 on file protects your rights and preserves your options.
What Information Does a C-3 Form Require?
The C-3 form asks for detailed information about you, your employer, and your injury. Completing it accurately is important because errors or omissions can delay your claim or give the insurer grounds to dispute it.
- Personal information: Your full legal name, address, date of birth, Social Security number, and contact information are required to identify you as the claimant in the Board’s system.
- Employer information: You must provide your employer’s name, address, and the name of their workers’ comp insurance carrier if you know it, so the Board can notify the correct parties.
- Injury details: The form asks for the date, time, and location of the injury, a description of how it happened, and the specific body parts affected.
- Medical treatment information: You must identify the medical providers who have treated you for the injury and describe the treatment you have received so far.
- Wage information: The form asks for your average weekly wage, which the Board uses to calculate your wage replacement benefit amount if your claim is approved.
- Witness information: If anyone witnessed your injury, their names and contact information should be included to support the circumstances you describe.
Taking the time to complete the form carefully and thoroughly strengthens your claim from the beginning.
Where and How Do You File a C-3 Form in New York?
The C-3 form can be filed online through the New York Workers’ Compensation Board’s website, by mail, or in person at a Board district office. Filing online is generally the fastest method and creates an immediate record of your submission. If you file by mail, sending it by certified mail with return receipt gives you documented proof of the date it was received.
Once the Board receives your C-3, it notifies your employer and their insurance carrier. The insurer then has a set period to either accept or dispute the claim. If the claim is accepted, benefits should begin flowing. If it is disputed, the Board will schedule a hearing before a Workers’ Compensation Law Judge to resolve the disagreement.
What Happens If You File a C-3 Form Late in New York?
The two-year deadline for filing a C-3 is serious, but the consequences of missing it depend on the circumstances. Filing late doesn’t automatically end your claim in every situation, but it creates significant obstacles. The Board may decline to hear your case, and the insurer will use the late filing as a basis to deny benefits. Certain exceptions apply, such as cases involving occupational diseases where the worker didn’t connect the condition to their job until later, but those exceptions require proof and legal argument.
For injuries that develop gradually, such as repetitive stress conditions or hearing loss, the two-year clock generally starts from the date you became disabled and knew or reasonably should have known the condition was work-related. If you are unsure when your deadline runs, don’t guess. Contact our workers’ compensation attorneys as soon as possible to get a clear answer before time runs out.
Is Filing a C-3 Form the Same as Reporting Your Injury to Your Employer?
No, and this is one of the most common misunderstandings in New York workers’ comp cases. Reporting your injury to your employer satisfies the 30-day notice requirement under Workers’ Compensation Law, but it does not file your claim with the Workers’ Compensation Board. These are two entirely separate obligations with different deadlines and different consequences for missing them.
Your employer is also required to file a form with the Board after learning of your injury, called the C-2 form, but you cannot rely on your employer to take that step on your behalf. Filing your own C-3 is the only way to ensure the Board has a record of your claim in your own words and from your own perspective as the injured worker.
What Should You Do After Filing a C-3 Form in New York?
Filing the C-3 is a critical step, but it’s the beginning of the process, not the end. There are several things you should do after submitting your form to protect your claim and keep it moving forward.
- Keep a copy of everything: Save a copy of your completed C-3 and any confirmation you receive from the Board showing the date and method of filing.
- Continue medical treatment: Attend all scheduled appointments and follow your doctor’s instructions. Gaps in treatment give insurers ammunition to argue your injury isn’t as serious as you claim.
- Respond to Board notices promptly: The Workers’ Compensation Board will send you notices about your case, including hearing dates and requests for information. Missing a deadline or failing to respond can hurt your claim.
- Track your lost wages: Keep records of every workday and shift you miss because of your injury, as this documentation supports your wage replacement claim.
- Don’t give recorded statements without counsel: The insurance company may contact you after your C-3 is filed. You are not required to provide a recorded statement, and doing so without legal advice can damage your case.
- Contact our NYC workers’ comp lawyers: If your claim is disputed, your benefits are delayed, or you receive a denial after filing, having legal representation significantly improves your chances of a successful outcome.
The period immediately after filing is when insurers look hardest for reasons to dispute or minimize your claim.
