Why a state-focused directory matters

Workers’ compensation is administered at the state level — eligibility, who must carry coverage, penalties for noncompliance, forms, and appeal rights all vary by jurisdiction. Relying on a federal summary alone leaves gaps that can cost your business in fines, premium surprises, or litigation. (dol.gov)
Many states publish employer-specific toolkits, required workplace posters, and electronic filing portals — these are the primary sources you must bookmark and use during onboarding, claims, and audits. Examples and links to state agencies follow. (dir.ca.gov)
Industry-specific exceptions, payroll thresholds, and self-insurance requirements make one-size-fits-all policies risky. Use state resources to verify coverage triggers and optional exemptions (corporate officer elections, household worker thresholds, seasonal-worker adjustments). (myfloridacfo.com)

Federal vs. state roles — quick primer

Federal (DOL/OWCP) administers workers’ compensation programs for federal employees and certain federal statutes (e.g., Longshore, Black Lung). Private-sector workplace coverage and rules are set by the states. If your employees are federal-covered groups, use DOL guidance; otherwise, default to your state board. (dol.gov)
OSHA enforces workplace safety standards that impact frequency and severity of comp claims; OSHA violations can affect defense during disputes and influence insurer behavior. Use OSHA guidance to reduce injuries and to remain prepared for inspections. (osha.gov)
NCCI and state rating bureaus collect payroll and claims data, calculate loss costs and experience modification factors, and publish manuals that insurers use to price policies in many states. If you manage premiums, the NCCI resources are essential. (ncci.com)

How to use this directory (a simple triage flow)

Identify your primary state(s) of operations (where payroll is paid and where work occurs).
Bookmark the state workers’ compensation board/department and the state insurance regulator (these are often separate). See Appendix for contact and portal examples. (dir.ca.gov)
For multi-state employers: decide if you will maintain a state-specific policy or handle out-of-state exposures with endorsements — consult your agent and confirm with the insurer and the state regulator.
Use the state site to: register for required notices, download employer forms, verify payroll thresholds, and check for e-filing / proof-of-coverage portals. (Examples below.) (agate.tdi.state.tx.us)

State snapshots: requirements you must know (authoritative examples)

Below are representative, authoritative state-level summaries. These illustrate the variability you must expect — use the linked state pages as your legal source of truth.

California (Division of Workers’ Compensation — DWC)

Workers’ compensation is mandatory for almost all employers; employers must provide claim forms and file the employer report when notified of an injury. The DWC manages claims processes, virtual hearings, and enforcement. Employers should review DWC’s employer pages for claim filing, notice requirements, and audit units. (dir.ca.gov)

Texas (Texas Department of Insurance — Division of Workers’ Compensation)

Texas is notable: most private employers may choose not to carry workers’ compensation (non-subscriber option), but they must report non-subscriber status annually; non-subscribers face different litigation exposure and reporting requirements for injuries. Employers who carry coverage must report injuries to carriers and meet other rules. Texas provides an Employer E-File portal and guidance for both subscribers and non-subscribers. (tdi.texas.gov)

New York (NYS Workers’ Compensation Board)

Most employers must carry coverage for one or more employees; employers must file first reports of injury (FROI) and maintain notices of compliance. The Board provides eCase and online filing portals and emphasizes timeliness — e.g., reporting a qualifying injury quickly to avoid penalties. (wcb.ny.gov)

Florida (Florida Division of Workers’ Compensation / CFO)

Florida requires coverage for most employers, with specific thresholds: construction employers generally must carry coverage with one or more employees; many non-construction employers must carry coverage when they have four or more employees. Self-insurer filing requirements and exemptions are explicitly regulated. Confirm construction/non-construction thresholds and owner elections on the state site. (myfloridacfo.com)

Note: The examples above are authoritative only for the states listed. Always confirm the current legal text, administrative rules, and portal addresses on the state pages linked in the Appendix. State laws and administrative bulletins change — bookmark the primary agency pages and check legislative updates. (ncci.com)

Quick comparison table — selected states at a glance

State	Mandatory Coverage?	Common Employer Threshold	Key Portal / Resource
California	Yes — mandatory for virtually all employers	All employers with employees; claims & FROI procedures required	CA DWC employer pages. (dir.ca.gov)
Texas	Optional (non-subscriber allowed)	Employers must report coverage status annually; non-subscriber reporting required	Texas DWC employer resources + Employer E-File. (tdi.texas.gov)
New York	Yes — most employers	One or more employees; file FROI and proof of coverage	NY WCB employer resources. (wcb.ny.gov)
Florida	Yes — industry thresholds	Construction: 1+; Non-construction: typically 4+ employees (varies by entity)	FL Division of WC compliance pages. (myfloridacfo.com)

(If you operate in other states, use the Appendix or your insurance broker to locate the exact board and portal. For multi-state operations, each work location’s state controls coverage triggers.)

Required forms, notices, and timelines (what to file and when)

Notice to employees: Most states require a workplace poster or notice informing employees of workers’ compensation rights and how to report injuries. Failure to post required notices can be a simple but expensive violation. (See CA, NY, FL for sample notices.) (dir.ca.gov)
First Report of Injury (FROI) / Employer Report: When an employee is injured, employers must file an employer report and provide the employee with claim forms within state deadlines — often within a day to a few days for the employer to provide forms and within 7–10–30 days to the board/insurer depending on the state. Check your state’s required timeframes. (dir.ca.gov)
Proof of coverage / employer reporting: Some states require employers to file proof-of-coverage or register with a state portal annually (Texas non-subscriber reporting is an important example). Self-insured employers and large employers may have additional filing requirements. (tdi.texas.gov)
Electronic filing & eCase portals: Many states now require or permit electronic filing for FROIs, employer reporting, and appeals. Use the state e-portals to minimize late filings and to access case documents. (wcb.ny.gov)

Practical tip: Create a state-specific process checklist in HRIS or payroll software so every reportable injury triggers: employee notice, employer form provision, insurer notification, OSHA reporting (if required), and state filing if the state requires employer-to-board submissions.

Employer action checklist: onboarding, payroll records, and audit readiness

Essential tasks to avoid surprises and premium adjustments:

During hiring/onboarding:
- Post state-mandated workers’ comp notices in English and Spanish (where required). (wcb.ny.gov)
- Capture full job descriptions and primary duties for correct class code assignment.
- Record status for corporate officers, owner elections, and independent contractor agreements (these affect coverage eligibility).
Ongoing payroll practices:
- Maintain accurate payroll records by state, by business unit, and by class code — critical for premium calculation and audits.
- Document contractor payments and verify exempt vs. employee status under state law.
Annual tasks and audit prep:
- Verify the proof-of-coverage filing and non-subscriber notification deadlines (TX example: annual reporting between February 1 and April 30 for coverage status). (tdi.texas.gov)
- Reconcile payroll detail reports with insurer-submitted payroll to the rating bureau (NCCI or state fund) prior to audit.
- Keep a “claims binder” with FROIs, employee reports, safety investigation notes, return-to-work documents, and medical release forms.
Create a claims response plan so every reported injury triggers consistent documentation, early-return-to-work planning, and timely communication with carriers.

Contractor tests, payroll exemptions, and what triggers mandatory coverage

State-by-state contractor tests: States use different tests to determine whether a worker is an employee (covered) or an independent contractor (often not covered). Tests typically include degree of control, method of payment, and whether the worker has their own business/practice. Always check the state agency’s guidance and the state’s worker classification tool. (workcompone.com)
Payroll thresholds and special categories:
- Construction trades: many states require coverage at lower employee counts (often 1+) for construction contractors. Florida explicitly differentiates construction vs non-construction criteria. (myfloridacfo.com)
- Corporate officer elections: several states allow corporate officers to elect exemption or require them to be covered; check the state filing process to make these elections properly.
- Household workers & agricultural seasonal employees: many states have specific thresholds and rules for these categories — treat them separately in payroll.
Practical example: If you hire an independent contractor for a construction job in Florida, that contractor may be treated as covered for certain purposes — confirm via the state’s contractor classification guidance before excluding them from payroll or insurance.

Self-insured vs. traditional workers’ comp: which option makes sense?

Decision factors:

Scale and cash flow: self-insurance requires capital reserves, stop-loss/reinsurance, and administrative infrastructure. It suits larger employers with stable payroll and robust safety programs. Smaller employers generally benefit from traditional insurance markets.
Predictability vs. cost reduction: self-insurance can lower long-term costs if your claim frequency is low; however, single catastrophic claims can spike costs. Traditional carriers spread risk across many employers. NCCI and state advisory resources provide experience rating methodologies to evaluate this tradeoff. (ncci.com)
Regulatory requirements: states set minimum requirements to self-insure (financial tests, security deposits, reinsurance). Check your state’s self-insurance office for eligibility, required filings, and annual audits. (myfloridacfo.com)

Brief decision matrix

Factor	Self-Insured	Traditional Insurance
Upfront capital	High	Low
Administrative burden	High	Low (insurer handles claims)
Control over claims	High	Moderate
Potential long-term savings	High (if low frequency)	Stable premiums based on risk pool

Reducing workers’ comp costs: evidence-based strategies

Return-to-work programs: Early, safe return-to-work plans reduce indemnity payments and preserve experience modification factors (mods). Collaborate with medical providers and carriers to design transitional duties. (See related cluster topic.) (ncci.com)
Safety incentives and prevention: OSHA-aligned safety programs reduce injury frequency; linking safety KPIs to premium credits or insurer discounts yields measurable results. (osha.gov)
Claims management: Prompt reporting, early investigation, and medical network coordination control claim severity. Keep detailed documentation — this helps during reserve challenges.
Payroll and class-code accuracy: Misclassified payroll or incorrect class codes during audits can trigger large premium adjustments. Maintain correct job descriptions and consult your broker during hiring or classification changes. See: How to Calculate Workers’ Comp Premiums: Payroll Thresholds, Class Codes and Experience Modifiers.

Claims handling best practices: how to file, defend and reduce claims

Immediate steps after an injury:
1. Secure medical care and document the incident (photographs, witness statements).
2. Provide the state-required claim form to the employee immediately (many states require this within one working day). (dir.ca.gov)
3. Notify the insurer and file any state-mandated employer report (FROI) within your state’s deadlines.
Investigation & documentation:
- Perform a root-cause analysis and implement corrective measures to prevent recurrence.
- Maintain a chain-of-custody for medical releases and ensure HIPAA-compliant communications.
Defense and litigation readiness:
- If a claim is disputed, prepare timely Notice of Controversy or required employer filings to preserve defenses. Many states require insurers to handle defense, but self-insured employers must be prepared to present evidence. (wcb.ny.gov)
Return-to-work planning:
- Design transitional duty descriptions, define maximum hours/duties, and get medical release parameters in writing.

Audit preparedness: payroll audits, class-code accuracy and avoiding surprise bills

Employers are audited to verify payroll, class codes, and experience details used to calculate premiums. Audits can create retroactive premium bills if payroll was underreported or misclassified. NCCI and state bureaus publish audit rules. (ncci.com)
How to prepare:
- Reconcile payroll reports to payroll tax filings and accounting ledgers before audit.
- Maintain job descriptions mapped to class codes.
- Keep subcontractor and 1099 documentation to defend classification and separation of payroll vs. contractor payments.
Example: If an auditor finds that certain workers were misclassified into a lower-rate class code, the insurer may reclassify payroll and issue an audit bill — proactively cleaning job descriptions reduces this risk.

Workers’ comp for high-risk industries: brief strategies

Construction, healthcare, and transportation consistently experience higher claim frequency and severity — implement industry-specific prevention programs, targeted training, and return-to-work commitments. Use state and federal hazard pages for industry resources (OSHA industry topics, state training grants). (osha.gov)
Specialty insured programs: consider loss-sensitive programs with large deductibles when your risk profile, cash flow, and safety controls justify it.

Common pitfalls & real-world examples

Pitfall: Treating independent contractors as contractors without confirming state classification — result: retroactive premiums and penalties. Remedy: run state classification tests and keep written contracts plus proof of independent business operations.
Pitfall: Missing state-specific posting or non-subscriber notice requirements (Texas example: required state reporting windows). Remedy: calendar the state filing windows and use the state portal for confirmations. (tdi.texas.gov)
Pitfall: Incorrect class codes or lumped payroll across multiple legal entities — remedy: set payroll coding rules and consult the insurer or broker before a corporate reorganization.

Sample employer posting language (adapt and confirm per state):

“If you are injured on the job, notify your supervisor immediately and seek medical attention. Employers in [State] are required to provide workers’ compensation benefits. Contact [State Board phone/URL] for your rights and [Company HR contact] to report this incident.”

Expert insights — practical governance & KPIs

KPI suggestions for the CFO/risk manager to track quarterly:
- Lost-time claim frequency (per 100 employees)
- Average days lost per claim
- Medical cost per claim
- Return-to-work rate within 30 days
- Experience modification trend (3-year trend)
Governance: assign a senior leader (HR or Risk) ownership for state compliance, keep a centralized “state compliance binder” (digital), and schedule semi-annual reviews with your broker and outside counsel where appropriate.
