Short answer: If you're leaving a Missouri contractor with fewer than 20 workers, state law allows continuation of its insurance under rules modeled after federal COBRA, including when you resign. Once that ends, marketplace coverage is generally most affordable if your business profit qualifies for credits. Without credits, Missouri's marketplace offers only EPO medical plans, while healthy owners can compare underwritten nationwide PPO coverage.

• Leaving a larger contractor
• My profit qualifies for a credit
• Shop is profitable and I'm healthy
• Shop is profitable and I have a condition
• Still deciding

You've earned your trade license, mastered the work and decided it's time for your name to go on the company van. I'm talking to Missouri HVAC professionals and electricians starting businesses after leaving contractors, along with owners operating small shops with one or two helpers. When you leave employment, your regular paycheck ends, and eventually your employer health insurance does too.

Missouri provides some breathing room. Leave a contractor employing fewer than 20 people, and state continuation rules can let you retain the group policy whether you resigned or were terminated, using terms based on federal COBRA. Eventually, many owners turn to marketplace coverage, where Missouri medical policies all use EPO networks. Premiums have also climbed. For someone age 40, the average benchmark rose from $489 monthly in 2025 to $605 in 2026, approximately 23.7%.

First determine how long your existing coverage can continue. Then answer the bigger question for the future: does your shop's expected profit make you eligible for a premium tax credit?

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

Small employers aren't subject to federal COBRA. Instead, Missouri addresses that situation through its continuation statute, RSMo 376.428. It allows workers losing group coverage when employment ends to keep that insurance "in the same manner" required by federal COBRA, without restricting eligibility to layoffs. Because the law doesn't specify a duration in months, ask the contractor or insurer to verify 3 details in writing: your eligibility, when continuation coverage expires, and the deadline to elect it. Also confirm the monthly premium, since you'll generally lose the employer's contribution.

Whatever continuation period your insurer verifies gives you time to establish your shop while retaining familiar physicians and your existing deductible. That's the main benefit during those early months. But the premium matters. Compare keeping that policy with immediately purchasing longer-term coverage. The calculations in running the COBRA numbers also apply to Missouri continuation insurance.

When continuation coverage expires, the law recognizes that as losing insurance, giving you 60 days to enroll through HealthCare.gov. Applications can generally be submitted before expiration, so start selecting your replacement policy a couple of months ahead.

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

In that case, federal COBRA usually governs. You can generally retain the policy for up to 18 months, paying as much as 102% of the total premium, and have 60 days to elect coverage. It's a longer option but often costly. Job-related coverage loss also provides 60 days to enroll in marketplace insurance immediately, so compare prices before committing.

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

Premium tax credits depend on household earnings after business costs, rather than your shop's total sales. During startup, paying for a van, equipment, tools, licenses and insurance can reduce your actual profit substantially. If those earnings qualify for credits, subsidized marketplace insurance will generally cost you less.

The picture changes as your business enters year two. Higher profits reduce your tax credit, and once income passes 400% of the federal poverty level, assistance ends following the expiration of enhanced credits. That cutoff is $63,840 for one person seeking 2027 coverage during open enrollment beginning November 1, compared with $62,600 for 2026. Because advance credits are settled when you file taxes, revise your application whenever earnings change.

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

Without subsidies, you pay the full 23.7% increase. For a 40-year-old purchasing benchmark coverage, that's another $116 monthly, or approximately $1,392 annually. Network restrictions matter too. According to federal government's 2026 plan data, every Missouri marketplace medical plan uses an EPO, generally covering nonparticipating providers only for emergencies. If you're in the Kansas City or St. Louis area and see physicians across a state border, verify network access carefully.

Those benchmark premiums represent statewide figures for 40-year-olds. Your individual quote will vary with your age, location by county, household members and chosen policy.

Paying full marketplace premiums for an EPO network doesn't appeal to every profitable shop owner. If you're healthy, another possibility is private medically underwritten insurance offering nationwide PPO access outside HealthCare.gov. Because insurers evaluate applicants' health, their covered population can be healthier, potentially allowing lower premiums than unsubsidized marketplace policies. You'll answer medical questions, and approval isn't guaranteed. The company may reject you or exclude existing conditions.

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

Living with a chronic condition or taking an expensive prescription doesn't automatically rule out private coverage. Sam Jaber can review the specifics and compare it with marketplace options. Whichever route you consider, verify that your physicians and hospitals participate, particularly if you receive care across state lines. Repeat the check each fall. Since all Missouri marketplace medical coverage uses EPO networks, confirming provider participation is especially important.
