How to Fill Out New York Form C-3 (w/Examples) + FAQs

If you got hurt on the job in New York, you must file Form C-3, the Employee Claim, with the New York State Workers’ Compensation Board to start your benefits. This single form opens your case, locks in your filing date, and tells the Board, your employer, and the insurance carrier that you want medical care and lost-wage checks under Workers’ Compensation Law §18.

Filing late, leaving boxes blank, or guessing on dates can sink an otherwise strong claim. According to the 2024 New York Workers’ Compensation Board Annual Report, the Board received over 143,000 new indexed claims in a single year, and a large share of denials trace back to incomplete or late C-3 filings.

Here is what you will learn in this guide:

  • 📝 How to fill out every line of the C-3, C-3.3, and related forms
  • ⏰ The exact filing deadlines under federal OSHA rules and New York law
  • ⚖️ How penalties, fines, and fraud charges apply to bad filings
  • 🏥 How the C-3 connects to the C-4 medical report and C-7 carrier denial
  • 💡 Real-world examples, mistakes to avoid, and answers to the top FAQs

What Form C-3 Is and Why It Matters

Form C-3 is the Employee Claim form used by the New York State Workers’ Compensation Board to formally open a workers’ compensation case. The injured worker, not the employer, files this form. The employer files a separate report, the Form C-2F Employer’s Report of Work-Related Injury/Illness, through the eClaims system.

The C-3 matters because it is the legal trigger that places your claim before the Board. Without it, the Board cannot index your case, schedule a hearing, or order the carrier to pay benefits. The form is governed by Workers’ Compensation Law §20, which gives the Board jurisdiction once a claim is filed.

The plain-English meaning is simple: no C-3, no claim. The consequence of skipping it is that the carrier can stop voluntary payments at any time and you have no legal record on file. A common misconception is that filing the OSHA 301 incident report at work counts as a workers’ comp claim. It does not.

For example, Maria, a hotel housekeeper in Buffalo, hurt her back lifting a mattress. Her supervisor wrote an internal incident report, but Maria never filed a C-3. Eighteen months later, when the carrier stopped paying, Maria had no indexed case, and she had to scramble to file before the two-year statute of limitations under WCL §28 ran out.

Federal Backdrop: OSHA and FECA

Before New York rules kick in, federal law sets the floor. The Occupational Safety and Health Administration (OSHA) requires most employers with more than 10 employees to record work-related injuries on the OSHA 300 Log within seven calendar days. That log is not a benefits claim. It is a recordkeeping duty.

Federal employees and certain maritime workers do not use the C-3. They file under the Federal Employees’ Compensation Act (FECA) using Form CA-1 or CA-2 through the U.S. Department of Labor. Longshore and harbor workers use the Form LS-203 under the Longshore and Harbor Workers’ Compensation Act.

The consequence of filing the wrong form is delay. If a federal postal worker mistakenly files a C-3 with New York, the Board lacks jurisdiction, and the worker may miss the much shorter 30-day FECA notice deadline. A common misconception is that any government worker uses the same forms. State, county, and most city workers in New York use the C-3, but true federal employees do not.

The C-3 Family of Forms

New York actually uses several “C-3” series forms, and each does a different job. Filing only one when you need two is a frequent error that delays payment. The Board lists every current form on the official forms page.

The main forms in the family include:

If you suffer a sudden injury, you use the standard C-3. If you develop carpal tunnel after years of typing, you use the C-3 EMP because of the special date-of-disablement rules under WCL §42. The consequence of using the wrong version is a Board notice asking for a new filing, which resets the clock and frustrates everyone.

Filing Deadlines You Cannot Miss

New York imposes layered deadlines, and missing any one can cost you money or your whole case. The headline rule is the two-year statute of limitations in WCL §28. You must file the C-3 within two years of the accident, or within two years of when you knew or should have known the injury was work-related.

But two years is the outer limit, not the safe one. You also must give your employer written notice within 30 days under WCL §18. Telling a coworker does not count. Telling a foreman verbally is risky. Send an email or a signed note and keep a copy.

The plain-English rule is: tell the boss in writing within 30 days, and file the C-3 as soon as possible after that. The consequence of missing the 30-day notice is a defense the carrier can raise to deny the claim outright. A common misconception is that going to the company clinic counts as notice. It usually does not unless the clinic shares the report with management.

For example, David, a construction laborer in Queens, fell from a scaffold on March 1, 2026. He told his foreman the same day but never put it in writing. He filed his C-3 in October 2026. The carrier filed a Form C-7 controverting the claim, arguing improper notice. David eventually won, but only after a hearing where the foreman testified, costing him four months of lost benefits.

Occupational Disease Clock

Occupational disease claims follow a different timer. Under WCL §40 and §42, the two-year clock starts on the date of disablement, not the first day of exposure. The date of disablement is usually the first day you missed work or the day a doctor told you the condition is work-related, whichever is later.

The consequence of misreading this rule is severe. Workers often assume their claim is dead because they were exposed to chemicals 15 years ago. In reality, if a doctor diagnoses occupational asthma today, the clock may have just started. A common misconception is that you cannot file decades after exposure. You can, if disablement is recent.

For example, Linda, a nail salon technician in Manhattan, breathed acrylate fumes from 2008 to 2024. In February 2026, a pulmonologist diagnosed her with occupational asthma using guidelines from the American Thoracic Society. Linda’s date of disablement is February 2026, and she has until February 2028 to file her C-3 EMP.

Step-by-Step: How to Fill Out Form C-3

The C-3 has roughly 18 numbered items, plus a signature block. Each line has nuance, and a wrong answer can stall payment. Always use the latest version from the Board’s C-3 page, because older versions get rejected.

You can file three ways: online through the Workers’ Compensation Board eCase portal, by mail to the district office, or by fax to (877) 533-0337. Online filing gives you a confirmation receipt, which is the safest proof of filing.

Items 1-5: Your Personal Information

The top of the form asks for your name, Social Security number, address, phone, date of birth, and gender. Use your full legal name as it appears on your Social Security card. The carrier matches you to the employer’s payroll using SSN, so a typo here causes weeks of delay.

The plain-English rule is to write the truth and double-check the numbers. The consequence of a wrong SSN is that the eClaims system cannot link your case to the employer’s policy. A common misconception is that you can use an ITIN instead. You can, but you must mark the box and attach proof, or the case will sit in suspense.

For example, Jamal, a warehouse worker in the Bronx, transposed two digits of his SSN. The Board indexed his case but the carrier could not match it to payroll. Six weeks of indemnity checks were delayed until Jamal filed an RFA-1LC request for further action to fix the record.

Items 6-9: Employer Information

You must list your employer’s exact legal name, address, and the name of the supervisor you told about the injury. Many workers write the trade name or the building name. The Board needs the legal entity that holds the workers’ comp policy, which you can verify on the WCB Employer Coverage Search tool.

The consequence of naming the wrong entity is a controverted claim. A common misconception is that you can write “the company” or “the restaurant.” You cannot. You need the corporate name, often ending in Inc., LLC, or Corp.

For example, Priya worked at “Joe’s Diner” in Syracuse, but the legal entity was “Upstate Hospitality Holdings LLC.” She wrote “Joe’s Diner” on her C-3, and the carrier said no policy existed under that name. She fixed it by checking the Coverage Search tool and amending the form.

Items 10-13: Accident Details

These boxes ask the date, time, exact location, and description of how the injury happened. Be specific. “Hurt my back at work” is not enough. Write: “On June 14, 2026, at 2:15 p.m., on the loading dock at 123 Main Street, Albany, NY, I lifted a 75-pound box of tile and felt a sharp pain in my lower back.”

The consequence of vague descriptions is that the carrier can argue the injury did not arise out of and in the course of employment, which is the legal test under WCL §10. A common misconception is that medical records will fill in the gaps. They might not, and your own words on the C-3 control.

For example, Carlos, a hospital orderly in Rochester, wrote only “back pain” on his C-3. The carrier denied based on a pre-existing degenerative disc finding. Carlos had to amend the form and add testimony that he was transferring a 250-pound patient when the pain hit, citing the Board’s transfer-injury case law.

Items 14-16: Body Parts and Medical Treatment

List every body part injured. If you hurt your neck, lower back, and right shoulder, write all three. If a part is missing from the C-3, the carrier can refuse to authorize treatment for it later.

The plain-English rule is: when in doubt, list it. The consequence of leaving a body part off is that you may need to file an RFA-1W request to add a site, and the carrier may demand an Independent Medical Examination under WCL §137.

You also must list each doctor, hospital, and clinic that treated you, with addresses. The treating doctor must be authorized by the WCB Health Provider Search, or the bills will not be paid.

Items 17-18: Wages and Lost Time

Item 17 asks your gross weekly wage, and Item 18 asks the dates you missed work. Your average weekly wage drives your benefit rate, capped at the maximum weekly benefit set yearly by the Board. For July 2025 through June 2026, the cap is $1,222.84 per week, set by WCL §25-a.

Include overtime, bonuses, tips, and the value of room and board if your employer provided them. The consequence of underreporting wages is a permanently lower benefit rate. A common misconception is that only base pay counts. It does not. WCL §14 requires inclusion of all earnings.

For example, Tanya, a server in Brooklyn, listed only her $5.65 tipped wage and missed her $700 weekly tip income. Her benefit rate was set at roughly $90 per week instead of more than $470. She had to file an RFA-1W to recompute her average weekly wage using credit-card tip records and IRS Form 4137.

Signature, Date, and HIPAA Release

Sign and date the form in ink or with a verified e-signature through eCase. Attach a completed Form C-3.3 HIPAA release so the carrier can request your medical records. Without the C-3.3, the carrier can delay payment under 12 NYCRR §300.38.

The consequence of skipping the C-3.3 is a 30-day delay while the carrier requests the form separately. A common misconception is that the C-3.3 gives blanket access to all health records. It does not. It is limited to records related to the claimed body parts and the prior 12 months by default.

Three Real-World Filing Scenarios

Below are three common scenarios with the action you take and the outcome that follows. Each maps to a real Board procedure.

Scenario 1: Construction Fall

Filing Move Resulting Outcome
File C-3 within 30 days listing back, neck, and right wrist Case indexed quickly; treatment authorized under WCL §13
Skip the C-3.3 HIPAA release Carrier delays accepting claim, files C-7 controversion
Wait 18 months, then file with vague description Carrier raises notice and causation defenses, hearing scheduled
File online through eCase with C-4 doctor report attached Indemnity payments start within 18 days under WCL §25

Scenario 2: Healthcare Needlestick

Filing Move Resulting Outcome
File C-3 same week and start post-exposure prophylaxis under CDC guidelines Treatment paid, monitoring authorized for one year
List only “needlestick” without source patient info Carrier may dispute exposure risk and seroconversion claim
Add psychiatric body part if PTSD develops Mental injury covered under Matter of Wolfe line of cases
Fail to file C-3 EMP if seroconversion occurs years later Occupational disease claim may be time-barred under §42

Scenario 3: Office Repetitive Strain

Filing Move Resulting Outcome
File C-3 EMP listing date of disablement as first missed workday Clock starts correctly under WCL §42
File standard C-3 with accident date set to first symptom Carrier denies, says no specific accident occurred
Attach C-4 from a WCB-authorized hand specialist Carpal tunnel diagnosis accepted, surgery authorized
Omit prior keyboard-heavy jobs from work history Apportionment dispute under WCL §15(7)

Three Named Examples in Detail

Robert, a 52-year-old union electrician in Long Island, fell off a ladder and broke his ankle. He filed his C-3 the next day through eCase, attached the C-3.3, and listed his full overtime average weekly wage of $1,840. The carrier accepted the claim within 12 days, and Robert received his first indemnity check at the maximum rate.

Aisha, a 34-year-old certified nursing assistant in Yonkers, hurt her shoulder transferring a patient. She delayed filing for nine months because she thought the company would handle it. When she finally filed, the carrier raised a late-notice defense under WCL §18. A judge excused the late notice because Aisha had told three supervisors verbally and the employer was not prejudiced.

Miguel, a 45-year-old line cook in Manhattan, suffered a grease burn on his forearm. He listed only the forearm on his C-3. Six weeks later, he developed reflex sympathetic dystrophy in his hand. Because he had not listed the hand, he had to file an RFA-1W to add a consequential injury, citing the Matter of Sandalo line of consequential-injury cases.

Mistakes to Avoid

These mistakes appear over and over in denied claims. Avoid each one.

  • Missing the 30-day written notice deadline under WCL §18 and losing your defense to controversion
  • Listing only some body parts and forcing later RFA-1W amendments that delay treatment
  • Underreporting your average weekly wage by leaving out tips, overtime, or bonuses required by WCL §14
  • Filing a standard C-3 for an occupational disease instead of the C-3 EMP, which forces refiling
  • Forgetting the C-3.3 HIPAA release, which lets carriers stall payment legally
  • Treating with a non-authorized provider not listed in the Health Provider Search, which voids bill payment
  • Writing vague accident descriptions that fail the “arising out of and in the course of” test under WCL §10
  • Using the employer’s trade name instead of the legal entity verifiable on the Coverage Search tool
  • Signing without dating, which the Board may reject under 12 NYCRR §300.1
  • Mailing the form without tracking and losing your filing-date proof when the envelope disappears

Penalties for Bad or Late Filings

Penalties cut both ways. Workers can lose benefits, and employers and carriers face fines for their own mistakes. Understanding the penalty matrix helps you push the right buttons.

For workers, the main penalty is a denied claim. If you file after two years, the case is dismissed under WCL §28. If your description does not fit “arising out of and in the course of employment,” the claim fails under WCL §10.

For employers, the Board fines up to $2,500 per ten-day period for failure to file the C-2F. Working without coverage triggers fines up to $2,000 per ten-day period plus criminal exposure under WCL §52. For carriers, a controversion later found unreasonable triggers attorney’s fees and assessments under WCL §25.

The consequence of fraud, by either side, is severe. Knowingly false statements on a C-3 are a Class E felony under WCL §114-a and can result in a permanent forfeiture of all indemnity benefits. A common misconception is that “stretching” the wage figure is harmless. It is not. The Board’s Office of the Inspector General prosecutes these cases.

How the C-3 Connects to Other Forms

The C-3 is the trigger, but several other forms drive the claim forward. Knowing the chain prevents gaps.

The Form C-4 is the doctor’s initial medical report. Without a C-4 from an authorized provider, the Board has no medical evidence and benefits stall. The Form C-7 is how the carrier denies, and it must be filed within 18 days of the first lost workday under WCL §25.

The Form OC-400 Notice of Retainer is filed by your attorney. The Form RFA-1LC requests Board action on a stalled case, and the Form RFA-2 is the carrier’s mirror version. Each form is a tool to keep the case moving.

A common misconception is that filing the C-3 alone gets you paid. It does not. You also need a C-4 in the file and a wage statement from the employer, called a Form C-240 statement of earnings, to lock in your benefit rate.

Do’s and Don’ts

These habits keep your claim healthy.

  • Do file electronically through eCase for instant proof of filing
  • Do keep copies of every page and every attachment in a folder labeled with your case number
  • Do see an authorized provider on the first visit so the C-4 is valid
  • Do report every body part, even minor ones, because adding parts later is harder
  • Do verify your employer’s legal name through the Coverage Search tool

Bad habits to avoid include the following.

  • Don’t sign a release the carrier sends without reading it; the C-3.3 is enough
  • Don’t return to work without a doctor’s note, because the WCL §15 wage rate may reset
  • Don’t post about the injury on social media, because carriers monitor public posts
  • Don’t miss an Independent Medical Exam scheduled under WCL §137 or benefits suspend
  • Don’t ignore mail from the Board; missing a hearing waives arguments

Pros and Cons of Filing the C-3 Yourself

Filing without a lawyer is an option for simple claims. There are tradeoffs.

Pros include:

  • No legal fees up front, though attorney fees are paid by the carrier under WCL §24 when fees are awarded
  • Faster initial filing because you control the timing
  • Direct communication with the carrier and Board
  • Full control over which body parts and dates you list
  • Useful for small medical-only cases under $5,000

Cons include:

  • Easy to underreport wages and lock in a low benefit rate
  • Hard to spot a controversion and respond on time
  • Difficult to navigate apportionment under WCL §15(7)
  • No help at hearings before a Workers’ Compensation Law Judge
  • Risk of missing schedule loss of use awards under WCL §15(3)

Key Court Rulings to Know

A few court rulings shape how the C-3 plays out. Each one matters when the carrier pushes back.

In Matter of Williams v. New York City Health and Hospitals Corp., the Court of Appeals held that the arising out of test under WCL §10 is broad and covers idiopathic falls when the workplace contributes. The consequence is that a fainting fall onto a hard floor at work is usually compensable, even if the fainting itself was not work-related.

In Matter of Johannesen v. New York City Department of Housing Preservation, the Court recognized stress-induced mental injuries as compensable under New York law. This expanded the body parts you can list on a C-3 to include psychiatric conditions, provided you back them up with a C-4 from a licensed psychologist or psychiatrist.

In Matter of Wolfe, the Board confirmed that consequential injuries flowing from a primary work injury are covered without a new C-3, as long as you file an RFA-1W amendment. The misconception this corrects is that every new symptom requires a new claim. It does not.

Filing Logistics: Online, Mail, and Fax

You have three filing channels, and each has nuances. Pick the one that gives you proof.

Online filing through eCase is the safest because the system stamps the date and time and gives you a receipt. You need an account, and you can upload PDFs of medical records and the C-3.3. Fees are zero.

Mail filing goes to the appropriate district office listed by the Board. Always send by certified mail with return receipt. The consequence of regular mail is no proof of filing, which can be fatal at the two-year mark.

Fax filing to (877) 533-0337 is allowed, but keep the fax confirmation page. A common misconception is that emailing the form to the Board counts as filing. It does not, unless sent through the secure portal.

Special Situations

Some workers face extra rules. Knowing them prevents surprises.

Undocumented workers are covered under WCL §17 and the Balbuena v. IDR Realty ruling. They use the same C-3 and can use an ITIN. Volunteers for fire and ambulance services use the VFBL or VAWBL forms instead of the C-3.

Public employees of New York City use the same C-3, but the City self-insures, and benefits flow through the Law Department’s Workers’ Compensation Division. Federal contractors on military bases may be covered by the Defense Base Act instead of New York law, which uses Form LS-203.

The consequence of using the wrong path is months of delay. A common misconception is that if you have any doubt, file the C-3 anyway. That is sometimes correct, but a duplicate filing in two systems can also slow things down. Call the WCB Advocate for Injured Workers at (800) 580-6665 before filing if you are unsure.

Frequently Asked Questions

Do I have to file Form C-3 if my employer already filed a C-2F?

Yes. The C-2F is the employer’s report and does not open your claim. You must file your own C-3 to preserve your rights and trigger Board jurisdiction under WCL §20.

Can I file Form C-3 online?

Yes. The eCase portal accepts e-signed C-3 forms with attachments, and it gives you a stamped receipt that serves as legal proof of filing.

Is there a deadline to file Form C-3?

Yes. You have two years from the accident date or date of disablement under WCL §28, and you must give written notice to your employer within 30 days under §18.

Do I need a lawyer to file Form C-3?

No. You can file alone, but an attorney’s fees are paid by the carrier when awarded under WCL §24, so legal help is often free to you in contested cases.

Can undocumented workers file Form C-3?

Yes. WCL §17 and the Balbuena ruling protect undocumented workers, who can use an ITIN in place of an SSN on the form.

Will filing Form C-3 get me fired?

No. Retaliation for filing is illegal under WCL §120, and you can file a discrimination complaint with the Board if your employer punishes you.

Do I need to attach Form C-3.3 with my C-3?

Yes. The C-3.3 HIPAA release lets the carrier verify medical records, and skipping it gives the carrier a legal reason to delay payment.

Can I add body parts to my C-3 later?

Yes. You file a Form RFA-1W to add consequential or missed body parts, but it is faster to list everything correctly the first time.

Does Form C-3 cover occupational diseases?

No. You must use the C-3 EMP for occupational diseases, because the date-of-disablement rules under WCL §42 differ from traumatic-injury rules.

Can I file Form C-3 for a mental-only injury?

Yes. Matter of Johannesen and later cases recognize mental-only stress claims, though you must support them with a C-4 from an authorized psychiatrist or psychologist.

Will filing Form C-3 affect my health insurance?

No. Workers’ compensation is separate from group health insurance, and your treatment for the work injury is paid by the carrier under WCL §13.

Can I file Form C-3 from out of state?

Yes. If your employer is based in New York or you were hired here, you can mail or fax the C-3 from any state, and the Board’s district offices accept out-of-state filings.
