Workers’ comp rules are state-specific
Workers’ compensation rules are state-specific. Do not use a national employee threshold, owner exemption, or construction carve-out as your answer. The U.S. Department of Labor links every state and territory to its workers’ compensation agency. Use the DOL directory to find the controlling office.
The contrast is sharp. California requires employers to carry workers’ compensation even when they have only one employee. California DWC employer guidance. Texas says private employers may choose coverage and that it is not required in most cases. Texas employer guidance.
Direct answer: check the state where people work, the kind of work they perform, their legal status, and any project or contract requirement before anyone mobilizes. A rule that is correct for a Texas private employer can be wrong for a California contractor.
When contractors must carry coverage
Use this order instead of guessing from crew size:
- Identify every work state. Use the official agency, not an insurance blog or a neighboring contractor’s setup.
- Count and classify people under that state’s test. Include part-time and family workers where the law does. Do not assume a 1099 form settles status.
- Check construction and trade carve-outs. California requires roofers to carry workers’ compensation even when they have no employees. California DWC employer guidance.
- Ask about project-specific proof. Before mobilizing, ask the contracting agency, owner, general contractor and licensing office whether the project or credential requires a certificate or other evidence beyond the state’s general rule. Treat the answers as questions to verify, not as a universal legal requirement.
- Document the answer. Keep the controlling state guidance and any project-specific response with the job file.
New York tells employers with people working in the state that they may be required to provide workers’ compensation, disability benefits and Paid Family Leave coverage. New York Workers’ Compensation Board. Texas non-subscribers must report their lack of coverage to the state and report specified work-related injuries, illnesses and deaths. Texas employer guidance.
The point is not that one state is stricter in every situation. The point is that the trigger and follow-on duties come from the controlling state program.
What to request in a written insurance proposal
The five official sources used in this guide establish coverage and worker-classification principles, not premium-rating rules. This section is a buying checklist, not a national cost formula.
Require the written proposal or an attached schedule to identify:
- the exact legal entity being insured;
- every state where work is expected;
- the people and owner or officer treatment included in the proposal;
- the operations and work scopes the proposal assumes;
- each stated assumption, exclusion and coverage limit;
- the amount due at binding, later payment dates and total proposed cost;
- the facts the insurer wants reported if the business changes; and
- the producer or insurer contact responsible for written corrections.
Compare proposals only after those fields match. If one proposal describes a different entity, workforce, state list or scope, the bottom-line totals are not answering the same request. Keep the selected proposal with the estimate and ask for a corrected version when hiring, locations or work change. For a fuller startup budget, add that written proposal to the real contractor license cost, not just the filing fee.
Subcontractors, COIs and worker classification
A certificate of insurance is an intake control, not a substitute for classification analysis. Collect it before mobilization, verify the named insured and policy dates, confirm the workers’ compensation section with the carrier or agent when needed, and calendar expiration. Keep the subcontract, invoices and scope with it.
The IRS says businesses must correctly determine whether service providers are employees or independent contractors. IRS worker-classification guidance. The IRS considers behavioral control, financial control and the type of relationship. IRS worker-classification guidance. It also says there is no magic number of factors and no single factor stands alone. IRS worker-classification guidance.
Those are federal tax principles, not a promise that a state workers’ comp agency uses the identical test. Run both analyses. A 1099, LLC name, invoice, or COI can be relevant evidence without deciding status by itself.
If you also need to separate insurance from surety obligations, read contractor bonds vs insurance.
Owner and officer exemptions are not universal
Do not assume that calling someone an owner or officer removes that person from workers’ compensation rules. Ask the official agency for the work state whether an exclusion or election is available and which current form and conditions apply. Then ask the insurer how that treatment will appear in the written proposal.
Keep a three-part file for every claimed exemption or exclusion:
- the current official rule or form supplied by the state program;
- the documents the agency requires to establish eligibility; and
- written confirmation of how the insurer will treat that person.
Also ask the customer, lender, landlord, general contractor and licensing office whether they require separate proof for the project or relationship. This checklist does not assume that any of them does; it identifies questions that must be answered for the actual job. Review the file when ownership, entity type, payroll, trade, or work state changes.
Seven compliance mistakes to catch before mobilization
The expensive failures start before the injury:
- Using a national threshold. State rules and trade carve-outs can point in opposite directions.
- Treating a 1099 as a legal conclusion. Classification follows the relationship and the applicable test.
- Accepting an expired COI. Track expiration and replacement before the sub returns to site.
- Bidding from an unexplained insurance number. Use a written proposal and ask what facts can change it.
- Assuming an owner label decides coverage. Verify the official state path and the insurer’s treatment.
- Assuming a state answer satisfies every job. Ask each contracting party and licensing office what proof it expects.
- Checking only the home state. The work location can create another state obligation.
Do not assume workers’ compensation answers the same questions as general liability insurance for contractors. Ask the licensed producer to explain, in writing, which people, injuries, operations and third-party claims each proposed policy addresses and which it excludes.
Workers’ comp for contractors FAQ
Do contractors always need workers’ comp after the first hire?
No single national threshold answers that. California requires coverage with one employee, while Texas generally lets private employers choose coverage. Check the state where the employee works and any construction-specific rule.
Can a contractor with no employees skip coverage?
Sometimes, but not as a universal rule. California says roofers must carry coverage even without employees. Ask the state agency whether another trade or owner rule applies to your facts.
Does paying a worker on a 1099 make that person an independent contractor?
No. The IRS looks at behavioral control, financial control and the type of relationship, and state workers’ comp tests may differ.
Is a subcontractor COI enough?
It is useful evidence, not the entire analysis. Verify the policy details, keep the subcontract and scope, track expiration, and separately review worker status under the applicable rules.
How should I budget the premium?
Get a written proposal for the exact entity, work states, people and scopes. Require assumptions, limits, exclusions, payment dates and total proposed cost in writing. This guide does not establish a national premium formula.
Where do I find the rule for my state?
Use the U.S. Department of Labor directory to reach the official workers’ compensation agency for the state or territory where the work occurs.
