Maine Workers' Compensation Insurance: Every Private Employer With an Employee Must Carry It, With No Minimum Headcount
Maine Workers' Compensation Insurance: Every Private Employer With an Employee Must Carry It, With No Minimum Headcount
If you have hired even one person to work in your Maine business, you almost certainly need workers' compensation insurance. Maine sets no minimum headcount. A business with one part-time employee has the same obligation as a business with fifty. The requirement applies to private employers, whether you run a restaurant in Portland, a boatyard on the coast, or a consulting firm out of a home office in Bangor.
This guide covers the core Maine workers' compensation requirements, the narrow exemptions, the coverage rules for owners, what happens if you go without coverage, and the steps to get compliant. It is written for owners who are forming a new business or adding their first employee to an existing one.
The core rule: every private employer with an employee must be insured
Under Maine law (39-A MRSA 401), every private employer must either buy a workers' compensation insurance policy or self-insure. There is no minimum employee count. The obligation starts when you have an employee, not when your business reaches a certain size.
The rule also reaches an independent contractor who hires and pays employees. Calling yourself a contractor does not remove the obligation if you are the one hiring and paying the workers doing the job. In that case, you are the employer of those workers and the requirement applies to you.
What this means in practice
Because there is no headcount floor, the question is not how big your payroll is. The question is whether anyone is working for you as an employee. If the answer is yes, you need a policy in force for that worker. Ask your insurance agent how each of your workers should be classified, because classification affects what your premium will be.
The two narrow exemptions
Maine's statute carves out two exemptions from the general rule. Both are narrow, and you should not assume your business fits one without checking.
| Exemption | Who it covers | Conditions |
|---|---|---|
| Domestic service | Employers of domestic service workers | Confirm the scope of this exemption with the Workers' Compensation Board |
| Seasonal or casual agricultural and aquacultural labor | Employers of seasonal or casual agricultural and aquacultural laborers | Employer's liability coverage of at least $25,000 with $5,000 in medical payments coverage (39-A MRSA 401(1)(A) and (B)) |
The agricultural exemption covers seasonal or casual laborers only. A farm or aquaculture operation with a regular, year-round crew generally falls outside it. If your operation depends on this exemption, confirm your status with the Board before you rely on it.
Sole proprietors, partners and corporate officers
A sole proprietor with no employees has no one to cover, so the requirement does not apply to that person's own work. The moment you hire someone, the rule applies.
Corporate officers get a different path. An officer who owns at least 20% of the voting stock may waive coverage for themselves, but only by filing an application that the Workers' Compensation Board approves. The waiver is not valid until the Board approves it. Once approved, the policy excludes that officer. Do not assume a pending application protects you. Until approval comes through, treat yourself as covered by the requirement.
The Board keeps the coverage records and the waivers, so approved waiver documents should be part of your permanent business files.
Who runs the program
Maine's workers' compensation program is administered by the Maine Workers' Compensation Board, not the Department of Labor. When you need to confirm coverage records, file a waiver, or ask how the statute applies to your workers, the Board is the agency to contact.
What happens if you go without coverage
Workers' compensation normally serves as the injured worker's remedy against the employer, and it shields the employer from a lawsuit over a work injury. That protection is called the exclusive-remedy defense. An employer that fails to insure loses that defense. An injured employee can then sue the employer or claim compensation, and the employer has no insurance to pay either outcome.
Penalties for operating uninsured are a separate issue. This guide does not state a penalty amount, and you should check the current structure with the Workers' Compensation Board and your insurance agent before making decisions based on it.
What coverage costs
Premiums depend on the class of work your employees perform, and rates vary by class. The rates for each class are not set out in this guide. To get accurate numbers, request quotes from licensed insurers or an insurance agent, and confirm the current rate information with the Board. Ask each quote provider to show the class codes they applied to your roles, so you can check that the classifications are correct.
Steps to get compliant
- Confirm your headcount status. Determine whether you have employees now or plan to hire them. One employee is enough to trigger the requirement.
- Check each exemption. Review the domestic service and agricultural exemptions, your sole proprietor status if you have no workers, and the officer waiver rules.
- Get quotes. Ask an insurer or agent for quotes that list the classification for each role.
- Bind coverage before your first worker starts. Do not wait until someone is injured to buy a policy.
- File any officer waiver first. If you want an officer excluded, submit the application to the Board and wait for approval before relying on the waiver.
- Keep your certificate of insurance on file. Store a copy with your business records and provide it when a client or agency asks for proof.
- Verify with the Board. Confirm your coverage and any waivers through the Workers' Compensation Board.
Forming the business: filings are not insurance
Many readers are forming an LLC or corporation at the same time. Those filings are separate from the workers' compensation requirement. Insurance does not register your entity, and a state filing does not satisfy the insurance rule. The Secretary of State's current fees for the main filings are below.
| Filing | Form | Fee |
|---|---|---|
| LLC Certificate of Formation | MLLC-6 | $175 |
| Corporation Articles of Incorporation | MBCA-6 | $145 |
| Annual report (LLC or corporation) | MLLC-13 or MBCA-13 | $85, due June 1 each year |
| Name reservation (120 days) | MLLC-1 | $20 |
| Assumed name for an LLC or corporation | ASUM-5 | $125 |
Maine does not offer online filing for formation documents. The forms are fillable PDFs that you print and mail or deliver with payment. The Secretary of State's pages read on 2026-10-28 state a processing time of 2 to 7 business days, which varies, so confirm the current timeline on the Secretary of State's site. Expedited handling costs $50 for 24 hour service and $100 for immediate service, and availability depends on staffing at the time of the request. Every LLC and corporation must also maintain a registered agent with a physical street address in Maine.
Starting with the first annual report, the schedule is the same for both entity types: the first report is due between January 1 and June 1 of the year after formation, and each later report is due June 1.
Licenses are separate from insurance
Maine issues no general statewide business license, and there is no general town license for an ordinary business. Licensing depends on the activity. Your municipal office licenses certain named activities under local ordinance, and fees differ from town to town. The Department of Health and Human Services licenses eating places, and the Department of Agriculture, Conservation and Forestry licenses food processors. State boards under the Department of Professional and Financial Regulation license trades, and Maine has no general contractor or HVAC license. The free Business Answers assistant at maine.gov/businessanswers can help you identify the permits that apply to your activity.

Frequently asked questions
Do I need coverage if I have only one part-time worker?
Yes. Maine has no minimum employee count, so a single employee triggers the requirement, unless one of the exemptions applies to that worker.
Can I avoid the requirement by hiring an independent contractor?
No. If a contractor hires and pays workers, the obligation falls on that contractor as the employer of those workers. Classifying people as contractors does not change the analysis.
I am a sole proprietor with no employees. Do I need a policy?
Not under this rule, because there is no one to cover. Once you hire your first employee, the requirement applies.
Who should I call first?
Start with a licensed insurance agent for quotes and classifications, then confirm rules and records with the Workers' Compensation Board. For formation filings, use the Secretary of State's Division of Corporations page. The Maine Small Business Development Centers at mainesbdc.org can also help you plan the business side of hiring.
