The short answer
If you work part time and your employer offers no health coverage, you are not stuck. The Health Insurance Marketplace is the usual answer, and a premium tax credit can cut the monthly cost sharply if your income is modest. If your income is low enough, Medicaid may cover you at little or no cost. A spouse’s plan or a parent’s plan (if you are under 26) can be cheaper still. Short-term plans look cheap but cover far less, and they are a bridge, not a home.
The case that confuses people most is the middle one: your employer does offer coverage, but the premium eats too much of your paycheck. There is a federal test for that. For 2026, employer coverage counts as affordable if the cheapest self-only plan costs no more than 9.96 percent of your household income. If it costs more than that, the offer is unaffordable, and you may qualify for a Marketplace subsidy instead.

Why part-time work falls through the cracks
Under the Affordable Care Act, the employer mandate applies to full-time employees, and full time means 30 or more hours a week on average. Employers with 50 or more full-time equivalent workers must offer affordable coverage to full-time staff or pay a penalty. Workers under 30 hours a week are outside that requirement. An employer can offer them coverage anyway, and some do, but nothing in the law forces it.
That leaves three common situations. First, you work under 30 hours and get no offer at all. Second, you work 30 or more hours but your employer is small, under 50 full-time equivalent workers, so the mandate does not apply. Third, your employer offers you a plan, but the premium is high relative to your income. Each situation has a different best next step, and the decision path below sorts them out.
Step one: the affordability test
Before you shop anywhere, find out whether your employer offer, if you have one, counts as affordable. The test has two parts, and both must pass for the offer to block a subsidy.
First, affordability. For plan years starting in 2026, the IRS sets the threshold at 9.96 percent of household income, up from 9.02 percent in 2025. Take the monthly premium you would pay for the cheapest self-only plan your employer offers, multiply by 12, and divide by your annual household income. If the result is 9.96 percent or less, the offer is affordable. If it is more, the offer is unaffordable, and the subsidy door opens.
Second, minimum value. The plan must be designed to pay at least 60 percent of the total allowed cost of covered benefits. Most employer plans pass this test. If a plan fails it, the offer does not block a subsidy even if the premium looks affordable. Your employer’s summary of benefits should state whether the plan provides minimum value.
Here is a worked example with round numbers. These are illustrations, not quotes.
Maria works 28 hours a week at a grocery store and earns $30,000 a year. Her employer offers her a plan, and the cheapest self-only option costs $250 a month, or $3,000 a year. Divide $3,000 by her $30,000 income and the result is 10 percent. That is above the 9.96 percent threshold for 2026, so the offer is unaffordable by a narrow margin, and she may qualify for a premium tax credit on the Marketplace.
Change one fact and the answer flips. If Maria earned $35,000 instead, the same $3,000 premium would be 8.6 percent of income, the offer would be affordable, and the subsidy door would stay shut for her. If her premium were $200 a month, or $2,400 a year, that would be 8 percent of $30,000, and again the offer would be affordable. The test is mechanical, and small changes in pay or premium move the result.
| Maria at $30,000 income | Maria at $35,000 income | |
|---|---|---|
| Cheapest self-only premium | $3,000 a year | $3,000 a year |
| Share of household income | 10.0 percent | 8.6 percent |
| 2026 threshold | 9.96 percent | 9.96 percent |
| Offer affordable? | No | Yes |
| Marketplace subsidy possible? | Yes | No |
One more wrinkle matters if you cover a family. Since January 1, 2023, the family glitch fix means family affordability is tested separately from your own. Your own offer can be affordable for you while the family coverage is unaffordable for your spouse and children, and in that case your family members may qualify for a subsidy even though you do not.
The decision path: five routes, in order
Work through these in order. Stop at the first one that fits, because it is usually the cheapest adequate cover.
Route 1: A spouse’s or parent’s plan. If your spouse has employer coverage, adding yourself to it is often the cheapest option, especially if the employer pays part of the family premium. If you are under 26, you can stay on a parent’s plan even if you live elsewhere or work part time. Compare the added premium against a subsidized Marketplace plan before you choose, because a subsidy can beat a spouse’s plan when income is low.
Route 2: Medicaid. If your household income is low, Medicaid may cover you at little or no cost, with no monthly premium in most states. Whether you qualify depends on your state. In states that expanded Medicaid, adults with income up to 138 percent of the federal poverty level generally qualify. In states that did not expand, the rules are narrower and many low-income adults fall into a gap. Medicaid has no open enrollment period, so you can apply any time of year. Check your state agency rather than guessing from a national income figure.
Route 3: The Marketplace with a subsidy. This is the main route for most part-time workers. You apply at HealthCare.gov or your state exchange, report your income and household size, and the system calculates your premium tax credit. The credit lowers your monthly premium, and if your income is modest, you may also qualify for cost-sharing reductions on a Silver plan that lower your deductible and copays. Open enrollment runs once a year, but losing employer coverage, a drop in hours that ends your coverage, or a move can open a 60-day special enrollment period.
Route 4: The Marketplace without a subsidy. If your income is too high for a credit, you pay the full premium. That is still real insurance: it covers essential health benefits, it cannot deny you for a pre-existing condition, and it caps your annual out-of-pocket costs. Compare the full-price premium against the cost of going uninsured, which is the entire bill for any hospital stay.
Route 5: A short-term plan, only as a bridge. Short-term plans are cheaper because they cover less. They can deny you for pre-existing conditions, they often exclude prescription drugs, maternity care, and mental health care, and they do not count as minimum essential coverage. Federal rules cap them at a limited duration, commonly cited as up to 12 months, but some states ban them or set shorter limits. Use one only if you need a few months of cover while you wait for open enrollment or a new job, and read the exclusions before you buy.
Checklist: sort out your cover in one sitting
- Find out whether your employer offers you a plan, and at what hours threshold. Ask HR, and get the cheapest self-only monthly premium in writing.
- Run the affordability test: annual self-only premium divided by annual household income. Above 9.96 percent for 2026 means the offer is unaffordable.
- Check whether the plan provides minimum value. The summary of benefits should say so.
- Check the two free or cheap routes first: a spouse’s or parent’s plan, and Medicaid in your state.
- If neither fits, apply on the Marketplace and let the system calculate your credit. Apply during open enrollment, or within 60 days of losing coverage.
- Compare Silver and Bronze after the credit, not before it.
- If you use a short-term plan, treat it as a bridge of a few months, read the exclusions, and check whether your state limits or bans it.
- Update your application when your hours, pay, or household size change.
Common mistakes to avoid
Assuming an employer offer blocks a subsidy. It only blocks a subsidy if it is affordable and provides minimum value. Run the numbers. A premium above 9.96 percent of household income for 2026 means the offer is unaffordable and the subsidy door is open.
Comparing sticker prices instead of post-credit prices. A $500 Silver plan can cost less out of pocket than a $180 short-term plan once the credit is applied, and it covers far more.
Letting a hours cut pass without acting. If your hours drop and you lose coverage, you have a 60-day special enrollment period. That window runs from the loss of coverage, not from the day you notice it.
Buying a short-term plan as a permanent answer. It is not ACA coverage. A serious illness or a pre-existing condition can leave you with bills the plan does not pay.
Frequently asked questions
Can my employer refuse to offer me insurance because I work part time?
Yes, in most cases. The employer mandate applies to employees working 30 or more hours a week, and only for employers with 50 or more full-time equivalent workers. Below that line, offering coverage to part-time staff is the employer’s choice.
Do I qualify for a subsidy if my employer offers me a plan?
Only if the offer is unaffordable or fails the minimum value test. For 2026, unaffordable means the cheapest self-only premium costs more than 9.96 percent of your household income. If the offer passes both tests, you can still buy a Marketplace plan, but you will not get a premium tax credit.
What if my income varies month to month?
Estimate your full-year income as best you can when you apply, then update the application when the numbers change. The credit is reconciled at tax time, so a careful estimate now saves a surprise later.
