Business insurance in Maine
Running a business in Maine means insuring against risks that reach from Portland's working waterfront to the North Woods. Once you hire your first employee—full-time, part-time, or seasonal—you owe them workers' comp, and Maine's maritime and forestry exposures push those rates above the national average. If you run vehicles, the state sets some of the country's higher auto minimums and mandates uninsured-motorist and medical-payments coverage too.

Maine requirements at a glance
- Workers' comp
- Required for virtually all employers with one or more employees — full-time, part-time, seasonal, or temporary. Narrow exceptions include sole proprietors with no employees, certain domestic workers in private homes, and some agricultural/aquacultural employers with six or fewer workers who instead carry specified employers' liability and medical-payments coverage. Non-compliance penalties run up to $10,000 or 108% of premiums owed, whichever is greater.
- WC market
- Competitive — private insurers available
- Min. auto liability
- 50/100/25 (bodily injury $50,000 per person / $100,000 per accident; property damage $25,000). Maine also mandates uninsured/underinsured motorist coverage at 50/100 and at least $2,000 in medical payments. A $125,000 combined single limit also satisfies the liability minimum.

- Maine Bureau of Insurance (within the Department of Professional and Financial Regulation)
What businesses in Maine need
Most Maine businesses build coverage from a few core lines. Workers' comp premiums run above the national average — roughly $83/month per employee versus the ~$74 benchmark — because forestry, commercial fishing, and maritime class codes carry high loss costs; maritime and harbor workers may also fall under the federal Longshore and Harbor Workers' Compensation Act rather than state WC. Coastal exposure matters too: nor'easters, wind, and storm surge drive commercial property premiums up along the shore, and flood damage requires a separate commercial flood policy. Maine is also unusual in mandating uninsured-motorist and medical-payments coverage on auto policies, not just liability.

Frequently asked questions
Does my Maine business need workers' comp if I only have one employee?
Yes. Maine requires workers' compensation once you have a single employee, and that includes part-time, temporary, and seasonal workers — one of the strictest thresholds in the country. Limited exceptions exist for sole proprietors with no employees, certain in-home domestic workers, and some agricultural or aquacultural employers with six or fewer workers who carry specified employers' liability and medical-payments coverage instead. Going without coverage can cost up to $10,000 or 108% of premiums owed, whichever is greater.
What are Maine's minimum auto liability limits for a business vehicle, and is that all I need?
The minimum is 50/100/25 — $50,000 bodily injury per person, $100,000 per accident, and $25,000 property damage (or a $125,000 combined single limit). But that isn't the whole requirement: Maine also mandates uninsured/underinsured motorist coverage of at least 50/100 and $2,000 in medical payments. For commercial vehicles, most agents recommend limits well above these state minimums to protect business assets.
