SOURCE-CHECKED
STATE
RESEARCH
The site is organized around state primary sources rather than a single national summary of workers' compensation exemption rules.
Identify the agency
Start with the state department, board, commission, or division responsible for administering workers' compensation.
Prioritize primary sources
Use current state material for coverage thresholds, entity eligibility, filing instructions, fees, and renewal rules whenever that material is available.
Trace the filing path
Record the form title, filing method, approval evidence, expiration rule, and any public verification tool provided by the state.
Separate supported facts from gaps
If an official source does not clearly support a penalty amount, owner category, filing path, or enforcement consequence, the guide qualifies or omits the point instead of presenting a guessed detail as fact.
Review for clarity and freshness
State pages are rechecked for source freshness, entity distinctions, stale filing instructions, and change events that can affect the result.
How the forms, renewal, and glossary data is verified.
The state forms reference and the renewal and effective-period table cover 50 states plus the District of Columbia. Each row was built from that jurisdiction's workers' compensation agency, statute, board, commission, state fund, or licensing body — not from insurer marketing or law-firm summaries — and each carries a source-check date of 2026-09-02. The renewal table reuses the same official source set as the matching form record so the two references cannot drift to different agencies for the same process. Timing-sensitive rows (for example Iowa, Kansas, North Dakota, Ohio, Tennessee, Vermont, West Virginia, and D.C.) were re-opened against current official material during a second review pass.
Where a state has no universal owner-exemption filing, the row says so plainly rather than inventing a form or a deadline. Fees are shown as “$0” only where an official source states there is no filing fee; a blank fee means no separate filing fee was verified, not that the process is free. A fee attached to an election into coverage — such as Ohio's $120 U-3 policy application fee — is labeled as what it is, not as an exemption fee. The glossary follows the same rule: every definition is tied to an official or recognized workers' compensation source, and state examples stay examples rather than becoming national rules.
AI can assist the workflow; it is not the authority.
AI tools may help organize research, compare source language, or produce draft prose. The publishing standard is source-first: the linked state agency, statute, commission, board, or licensing material controls the factual statement. When the public source set does not support a neat answer, the page preserves that uncertainty and points the reader back to the responsible agency or carrier.
