Workers' compensation is a form of insurance that employers are required to carry in most states, not something you purchase yourself
Your employer buys workers' compensation insurance from a private carrier, a state fund, or—in some states—self-insures if they meet certain financial thresholds. The insurance covers medical bills and a portion of lost wages if you suffer a work-related injury or illness. You do not pay premiums for this coverage; your employer does. The cost to them varies based on the industry, the company's claims history, and the number of employees.
The reason this matters for understanding money movement is that workers' comp is one of the few insurance products where the person covered has no direct financial relationship with the insurer. You file a claim with your employer or their claims administrator, not with an insurance company. The insurer pays the medical provider and you directly, but you never see an invoice or a bill to pay.
Most states require employers with a certain number of employees—typically three or more, though some states set the threshold at one—to carry this insurance. A few states allow employers to self-insure if they can prove they have enough money set aside to cover claims. Some states operate their own insurance funds that employers must use or can choose as an alternative to private carriers.

How the insurance requirement works by state
Every state except Texas requires employers to carry workers' compensation insurance or meet an exemption. Texas allows employers to opt out entirely, which means some Texas workers have no workers' comp coverage at all. In states where it is mandatory, the threshold for which employers must carry it varies: most require coverage for three or more employees, but some require it for one or more. A handful of states exempt certain industries, such as agricultural workers or domestic workers, though many states have narrowed these exemptions in recent years.
Some states operate a state fund—a government-run insurance program that employers must use or can choose instead of private insurance. Examples include the state funds in California, Ohio, Washington, and Wyoming. Other states are "competitive" states where employers can buy from private insurers, self-insure if they meet financial requirements, or in some cases purchase coverage from a state fund. A few states are "monopoly" states where the state fund is the only option.
The rules about who must be covered also vary. Most states cover employees but exempt owners, partners, and sometimes corporate officers. Independent contractors are typically not covered unless the employer misclassifies them; if that happens, the worker may have grounds to challenge the classification and claim benefits.
What happens when you report a work injury
When you suffer a work-related injury or illness, you must report it to your employer as soon as possible. Most states require you to report within a specific window—often 30 days, though some allow longer. Your employer then reports the claim to their insurance carrier or state fund. The insurer assigns a claims administrator or adjuster who will contact you to gather information about the injury.
The claims administrator will ask for details about how the injury occurred, what medical treatment you have received, and whether you have missed work. They may request medical records from your doctor. If the injury is accepted as work-related, the insurer will begin paying for medical care and, if you are unable to work, will start sending you wage replacement payments. This process typically takes one to three weeks, though it can be faster for straightforward injuries.
If the insurer denies the claim—arguing that the injury was not work-related or that you caused it through misconduct—you have the right to appeal. The appeal process varies by state but usually involves filing a formal objection with your state's workers' compensation board or agency. You may be may have access to to a hearing before a judge or hearing officer.
Medical coverage and wage replacement amounts
Workers' compensation covers all reasonable medical treatment related to your injury: doctor visits, surgery, physical therapy, medications, and medical devices. You typically do not pay out-of-pocket for covered care; the insurer pays the provider directly. In some states, you have the right to choose your own doctor. In others, the insurer assigns you to a doctor or you must choose from a network.
Wage replacement—called temporary disability benefits if you are expected to recover, or permanent disability benefits if the injury causes lasting harm—is a percentage of your average weekly wage before the injury. The percentage varies by state but is typically 60 to 70 percent of your pre-injury wage. There is usually a maximum weekly benefit amount set by the state, which means high earners may receive less than the full percentage. There is also usually a waiting period—often three to seven days—before wage replacement begins, though some states waive this if you are out of work for more than a certain number of days.
If your injury is permanent and causes lasting disability, you may receive a lump-sum settlement or ongoing payments. The amount depends on the body part injured, the degree of disability, and your state's benefit schedule. Some states allow you to settle a claim with the insurer for a one-time payment in exchange for giving up the right to future benefits.
What to do if your employer does not carry insurance
If you are injured at work and discover your employer does not carry the required workers' compensation insurance, you have options. First, report the violation to your state's labor department or workers' compensation board. They can investigate and fine the employer. Second, you may be able to file a claim directly against your employer in civil court for negligence, which can result in a larger award than workers' comp but is harder to prove and takes longer.
Some states have an uninsured employers fund that pays claims when an employer fails to carry required insurance. If your state has one, you can file a claim with that fund. The fund may then pursue the employer to recover what it paid out. Check your state's workers' compensation agency website to learn whether this option exists in your state.
If you are injured and unsure whether your employer has insurance, ask your HR department or your employer directly. By law, employers must inform you of their coverage. If they refuse to answer or you suspect they are lying, contact your state's labor department.
How premiums are set and what affects the cost to employers
Employers pay premiums based on three main factors: the industry classification of the business, the company's payroll, and the company's claims history. A construction company pays much higher premiums than an office-based business because construction work carries higher injury risk. Within an industry, a company with a history of claims pays more than one with few or no claims. This creates an incentive for employers to invest in workplace safety.
Premiums are calculated as a rate per $100 of payroll. For example, if a construction company has a rate of $15 per $100 of payroll and pays $500,000 in annual wages, the premium would be $75,000. Rates vary widely by state and industry; a low-risk office job might have a rate of $0.50 per $100 of payroll, while high-risk work might be $20 or more.
Employers can reduce their premiums through safety programs, return-to-work programs, and claims management. Some insurers offer discounts for companies that complete safety training or implement ergonomic improvements. This is why some employers are invested in preventing injuries—it directly affects their bottom line.
Your rights and what you cannot waive
You cannot waive your right to workers' compensation benefits. If your employer asks you to sign a document giving up your right to file a claim in exchange for employment, that agreement is void in every state. You also cannot be fired or retaliated against for filing a workers' compensation claim. If you are terminated shortly after filing, you may have grounds for a wrongful termination lawsuit.
You have the right to medical treatment for a work-related injury regardless of whether you were partially at fault. Workers' compensation is a "no-fault" system, meaning you do not have to prove your employer was negligent; you only have to show the injury arose out of and in the course of employment. The trade-off is that you generally cannot sue your employer for additional damages, even if they were grossly negligent.
If you disagree with a decision by the insurer—such as a denial of benefits or a information that your injury is not work-related—you have the right to appeal. Most states provide free or low-cost legal representation through a workers' compensation attorney, and many attorneys work on contingency, meaning they take a percentage of your award rather than an upfront fee.
Frequently Asked Questions
Does workers' compensation cover mental health conditions or stress-related illness?
Some states cover mental health conditions if they result from a physical injury or a specific traumatic event at work. A few states cover occupational stress or burnout, but this is rare and usually requires proof that the stress was extraordinary compared to normal job duties. Coverage varies significantly by state, so check with your state's workers' compensation board for the rules in your area.
What if I was injured at work but did not report it right away?
Most states allow you to report an injury within 30 days, though some allow longer. If you miss the important date, you may lose your right to benefits. However, if the injury was not when ready obvious—such as a repetitive strain injury that develops over time—the clock may start when you first notice the problem or when a doctor diagnoses it. Report any work-related injury as soon as you become aware of it.
Can I choose my own doctor, or does the insurance company assign one?
This depends on your state. Some states let you choose your own doctor from the start. Others require you to see a doctor selected by the insurer for the initial evaluation, then allow you to switch. A few states let the employer choose the doctor. Ask your claims administrator or check your state's workers' compensation board website to learn the rule in your state.
What happens if I recover and then the injury gets worse later?
If your condition worsens after you have returned to work, you may be able to reopen your claim. The process and time limits for reopening vary by state. Contact your claims administrator or your state's workers' compensation board to learn whether you can file for additional benefits.
Do I have to pay taxes on workers' compensation benefits?
Workers' compensation benefits are generally not subject to federal income tax. However, if you receive workers' comp and also receive Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI), the workers' comp payment may reduce your federal benefits. Consult a tax professional or your state's workers' compensation agency if you receive multiple benefits.
