If your employer offers health coverage, you might assume it’s automatically your best option. Often it is, but not always. Marketplace (ACA) plans can be a smart alternative in some situations, and a costly mistake in others. Here is how to compare them clearly.
How the two options compare
Cost. Employer plans are usually paid partly by your employer, which lowers your share of the premium. Marketplace plans have no employer contribution, but you may qualify for premium tax credits that reduce your monthly cost.
Flexibility. Employer plans offer one or a few options chosen by the company. The marketplace lets you choose among many plans, metal tiers (Bronze, Silver, Gold, Platinum), insurers, and networks in your state.
Coverage quality. Both must cover essential health benefits and cannot deny you for pre-existing conditions. The real differences are in the details:
- Networks: Are your doctors and hospitals in network?
- Deductible and out-of-pocket maximum: What do you pay before and after coverage kicks in?
- Prescription formulary: Are your medications covered, and at what tier?
- Family coverage: How much does it cost to add a spouse or children?
Compare total expected annual cost, not just the monthly premium.
When declining employer coverage can make sense
Employer coverage is generally the stronger choice because of the employer contribution. But the marketplace may be worth a look if:
- Your employer plan isn’t “affordable.” For 2026, the IRS treats employee-only coverage as affordable if it costs no more than roughly 9.96% of household income. If it costs more, or if it doesn’t meet minimum value (covering at least 60% of costs), you may qualify for marketplace tax credits.
- Family coverage is very expensive. Since the 2023 fix to the so-called “family glitch,” affordability for family members is measured by the cost of family coverage, not just employee-only coverage. Dependents may qualify for credits when family premiums are out of reach.
- Your preferred doctors or medications aren’t covered by the employer plan but are on a marketplace plan.
- You want a different plan type, such as a lower-premium plan because you rarely use care.
How premium tax credits affect the comparison
Premium tax credits are based on your household income and the cost of the benchmark Silver plan in your area. Important points:
- You generally cannot receive credits if you’re offered affordable, minimum-value employer coverage, even if you decline it. Declining it could mean paying the full marketplace price.
- The enhanced credits that temporarily removed the income cap expired after 2025, so the income limit of 400% of the federal poverty level applies again for many households. Check current rules for your income before deciding.
- Credits are reconciled when you file taxes. If your income ends up higher than estimated, you may owe some back.
Always run real numbers for your household before you decline a workplace plan.
Qualifying life events that open the marketplace
Outside of open enrollment (typically November 1 through January 15 in most states), you need a Special Enrollment Period. Common qualifying events include:
- Losing job-based coverage, including through a layoff, reduced hours, or retirement
- Moving to a new area with different plan options
- Marriage, divorce-related loss of coverage, birth, or adoption
- Aging off a parent’s plan at 26
- Changes in household income that affect eligibility (in some cases)
You typically have 60 days from the event to enroll, so don’t wait. Note that simply wanting a different plan, or declining employer coverage, is not a qualifying event. Be aware of your employer’s own enrollment window too.
Questions to ask before you decide
- What is my total yearly cost under each option, including premiums, deductibles, and expected care?
- Are my doctors, hospitals, and prescriptions covered?
- Is my employer plan considered affordable, and would I still qualify for credits?
- What happens if I lose the marketplace plan or my employer coverage changes?
