Short answer: Leaving a contractor under 20 employees, Missouri lets you keep its plan on terms modeled on federal COBRA, even if you quit. After that, if the shop's profit earns a tax credit, marketplace coverage with the credit usually costs least; above it, every marketplace plan is an EPO, so a healthy owner can price underwritten nationwide PPO plans.

You hold the license, you know the work, and you are ready to put your own name on the van. This page is for Missouri electricians and HVAC technicians leaving a contractor to open a shop, and for owners already running one with a helper or two. The paycheck stops when you leave, and so does the company health plan, eventually.

Missouri gives you a runway. If the contractor you are leaving has fewer than 20 employees, state continuation lets you keep its group plan on terms modeled on federal COBRA, whether you quit or are let go. After that, the marketplace is where most people land, and in Missouri every medical plan on it uses an EPO network. Prices there rose too: the average benchmark premium for a 40-year-old went from $489 a month in 2025 to $605 in 2026, about 23.7% more.

Sort out the runway first, then the question that decides the long-term plan: will the shop's profit qualify you for a premium tax credit?

If you're leaving a contractor with fewer than 20 employees

Federal COBRA does not apply to employers that small. Missouri's continuation law, RSMo 376.428, fills that gap: it lets people whose coverage ends with their employment continue the group plan "in the same manner" federal COBRA requires, and it is not limited to layoffs. The statute itself names no number of months, so get the contractor or its insurer to confirm in writing three things: that you qualify, the date your continuation ends, and the election cutoff. Ask what the monthly cost will be, since the employer's share usually goes away when you leave.

However long your insurer confirms, that time covers the first stretch of running your own shop, which is the useful part: you keep the same doctors and deductible while the work ramps up. The cost is the catch. Weigh the monthly bill against starting your long-term plan right away; running the COBRA numbers works the same way for state continuation.

The law treats the end of continuation as a loss of coverage, which opens a 60-day enrollment period on HealthCare.gov. You can generally apply ahead of the end date, so pick the next plan a couple of months before your end date.

If the contractor you're leaving has 20 or more employees

Then federal COBRA generally applies instead: up to 18 months on the same plan at up to 102% of its full cost, with 60 days to elect it. Longer, but usually expensive. Leaving the job also opens the 60-day window to buy a marketplace plan right away, so price both before you sign anything.

If the shop's first-year profit qualifies for a credit

The premium tax credit is based on household income after business expenses, not on what the shop bills. A first year with a van, tools, test equipment, licensing and insurance to pay for can leave a much smaller profit than the invoices suggest. Land in the credit range and the marketplace, with the credit applied, is usually your least costly route.

Year two is where it shifts. As the shop's profit grows, the credit shrinks, and past the 400% line of the federal poverty level, $63,840 for a single person on 2027 coverage chosen in open enrollment from November 1 ($62,600 on 2026 coverage), it disappears now that the enhanced credits have ended. Advance credits are reconciled at tax time, so update your application as the numbers change.

Once the shop earns past the credit, if you're healthy

At full price, the 23.7% increase is yours: $116 more a month for a 40-year-old buying the benchmark plan, about $1,392 more a year. The network is the other limit. In the federal government's 2026 plan data, Missouri's marketplace sells only EPO medical plans, and an EPO generally pays for out-of-network care only in an emergency. If you live on one side of the Kansas City or St. Louis metro and your doctors are across the state line, that is worth checking before anything else.

The benchmark figures are statewide averages at age 40. Your own price depends on age, county, household and plan.

For many shop owners above the line, full price for that network is hard to justify, and a healthy owner can look elsewhere: private plans sold off the marketplace that use medical underwriting and nationwide PPO networks. They take applicants based on health, so they insure a healthier group than the marketplace, and a healthy owner may undercut the full marketplace premium. Expect health questions; the insurer may accept you, decline you, or exclude a condition you already have. Each plan sets its own benefits, so go through them; our underwriting explainer covers the review.

Once the shop earns past the credit, if you have a condition

If you live with a long-term illness or a costly monthly prescription, stay on a HealthCare.gov plan even at full price. Those plans cannot turn you down or charge more for your health, and they include the essential benefits; an underwritten plan could decline you or exclude the condition. Because every plan is an EPO, confirm that your doctors and hospital are in the network, including any across the state line, and check again every fall.
