How sole proprietor workers comp works in Michigan
A sole proprietor is the simplest business form: one person, no separate legal entity, all income reported on Schedule C. Michigan does not require sole proprietors to cover themselves. Owners can elect out by filing an exclusion form, lowering premium but giving up workers comp benefits if they are injured at work. If you have at least one employee, you almost certainly need a policy regardless of whether you cover yourself.
Cost for a sole proprietor in Michigan
Premium is rated on payroll. The owner draw on Schedule C is typically rated at the state minimum payroll for sole proprietors (often around $50,000 annualized) when the owner elects in. The class code drives the rate per $100, ranging from clerical at well under $1 to roofing or trucking at $20 or more in Michigan. A solo operator on a low-rate clerical code who elects in often pays only the carrier minimum (typically $250 to $500), while a contractor with a single helper can run from a few hundred to a few thousand a year depending on payroll. Schedule credits up to 25% are typical for low-loss accounts in Michigan.
When to elect in vs out
Electing in makes sense if your work is hands-on (contractor, trucker, roofer, landscaper) because workers comp is the only insurance that pays both medical and lost-wage benefits with no deductible. Electing out makes sense if your work is low-risk and you have personal health insurance plus disability coverage that replaces workers comp at lower cost. Run the math on minimum premium versus an individual disability policy before deciding.
