Health Insurance for Part-Time Workers

Why most part-time workers don't get employer coverage

The ACA's employer mandate only applies to "applicable large employers" (ALEs) — companies with 50 or more full-time equivalent employees. And even those employers are only required to offer coverage to workers who average 30 or more hours per week, or 130 hours per month. If you fall below that line, your employer has no legal obligation to cover you.

Some employers do offer coverage to part-time workers voluntarily. Starbucks, Costco, and UPS are frequently cited examples. But they're exceptions. According to the Bureau of Labor Statistics, only about 24% of part-time workers have access to employer-sponsored health insurance, compared to 87% of full-time workers.

If your employer doesn't offer you coverage, the marketplace is your primary option.

The marketplace works well for part-time incomes

The ACA marketplace (HealthCare.gov or your state's exchange) is open to everyone regardless of employment status or hours worked. Plans cover essential health benefits, cannot exclude pre-existing conditions, and are eligible for premium tax credits based on household income.

For a single person in 2026, subsidies are available if your annual income is between $15,960 (100% of the federal poverty level) and $63,840 (400% FPL). Many part-time workers fall squarely in this range. A person earning $25,000 a year, for example, is at roughly 157% FPL and would receive a substantial subsidy — often enough to bring a Silver plan premium down to $50-$100 per month.

If your income is below 250% FPL ($39,900 for an individual) and you choose a Silver plan, you also get cost-sharing reductions. These lower your deductible, copays, and out-of-pocket maximum. At 150% FPL, a CSR Silver plan covers about 94% of your medical costs — better than a Platinum plan.

Calculating income when you work multiple part-time jobs

The marketplace asks for your total expected household income for the year. If you work two or three part-time jobs, you add up the income from all of them. The same goes for any side income — selling on Etsy, driving for a rideshare app, tutoring. It all counts toward your Modified Adjusted Gross Income (MAGI).

This matters because your subsidy is based on where your total income falls relative to the federal poverty level. Someone with one job earning $28,000 and someone with three jobs totaling $28,000 get the exact same subsidy.

A few things to watch out for:

• Variable hours mean variable income. If your hours fluctuate week to week, estimate your annual income based on what you've earned so far and what you realistically expect. You can update your marketplace application mid-year if things change significantly.
• Don't underestimate. If your actual income ends up higher than what you reported, you'll owe back some or all of the excess subsidy at tax time. In 2026, there is no repayment cap on excess advance premium tax credits, so the full amount is on the hook.
• Don't forget tips and cash income. All taxable income counts. If you receive cash tips, report them accurately on your marketplace application. The IRS reconciles your subsidy against your actual tax return.

When your employer offers coverage you can't afford

Some part-time workers do get offered an employer health plan — but it costs too much relative to their paycheck. The ACA has a specific test for this called the affordability threshold.

For 2026, an employer plan is considered "affordable" if the employee's share for self-only coverage costs no more than 9.96% of their household income. If your employer plan exceeds that percentage, you can turn it down and buy a marketplace plan with subsidies instead.

Example: You earn $22,000 per year. 9.96% of that is $2,191 per year, or about $183 per month. If your employer charges you $200 per month for the cheapest individual plan, that plan is officially unaffordable under ACA rules. You can decline it and get subsidized marketplace coverage.

If your employer plan costs less than the threshold, it's considered affordable even if it seems expensive to you. In that case, you can still buy a marketplace plan, but you won't qualify for premium tax credits.

One important detail: the affordability test only looks at the cost of employee-only coverage (just you, not your family). This is the so-called "family glitch" fix — as of 2023, family members can separately qualify for marketplace subsidies if the employee's cost for family coverage is unaffordable, even if the employee-only rate passes the test.

Estimate your subsidy

Income too low for subsidies? Check Medicaid.

If your annual income is below 100% FPL ($15,960 for a single person), you generally don't qualify for marketplace premium tax credits. But in the 40 states that have expanded Medicaid, adults earning up to 138% FPL ($22,024) qualify for Medicaid, which is free or nearly free coverage.

If you live in a state that hasn't expanded Medicaid and earn below 100% FPL, you may fall into the "coverage gap" — too little income for marketplace subsidies, but not qualifying for Medicaid in your state. This affects roughly 1.5 million Americans, most of them in the South. In this situation, you can still buy a marketplace plan at full price, or look into community health centers that offer care on a sliding-fee scale.

Choosing a plan tier

For part-time workers with lower incomes, two options tend to stand out:

Silver with CSR is almost always the best value if your income is below 250% FPL. The cost-sharing reductions only apply to Silver plans, and they can turn a standard Silver plan into something with a $200 deductible and $10 copays. If you qualify for CSR, pick Silver.

Bronze plans have the lowest monthly premiums and may even cost $0 per month after subsidies. The tradeoff is a high deductible (often $7,000+), so you'd pay full price for most care until you hit that threshold. This works if you're young, healthy, and mainly want protection against catastrophic costs.

Gold plans rarely make financial sense at lower incomes because the premium is higher and you don't get CSR benefits. Silver with CSR typically provides equal or better coverage at a lower total cost.

Key dates and enrollment

Open Enrollment for 2026 coverage ran November 1, 2025, through January 15, 2026. If you missed it, you can still enroll during a Special Enrollment Period if you experience a qualifying life event:

• Losing other health coverage (employer plan, Medicaid, COBRA)
• Moving to a new ZIP code with different plan options
• Getting married or having a baby
• A change in income that newly qualifies you for subsidies

If you recently started a part-time job after being on an employer plan, losing that employer coverage triggers a 60-day window to sign up on the marketplace.

What to do right now

• Add up your expected income from all sources for the year — every part-time job, side gig, and other taxable income
• Use the subsidy estimator above to see what you qualify for
• If your employer offers a plan, calculate whether it passes the 9.96% affordability test before deciding to take it or go to the marketplace
• If your income might be below 138% FPL, check whether your state expanded Medicaid — you may qualify for free coverage
• Update your marketplace application if your income or household size changes during the year so your subsidy stays accurate
