ACA marketplace vs. employer health insurance
When to take your employer's plan and when to shop the marketplace.
Most working Americans get health insurance through an employer, but the ACA marketplace is a real option — sometimes a better one. Here’s how to decide.
When employer coverage usually wins
- Employer pays significant portion of premium (typical: 70-85%)
- Your household income is above ACA subsidy thresholds
- Family members all covered under one plan
- Network access is good for your doctors
- Plan structure (deductibles, copays) fits your usage
When ACA marketplace usually wins
- Self-employed, freelance, or contract worker without employer coverage
- Recent job loss or job transition — marketplace plans bridge gaps
- Spouse with great coverage — better to be on theirs than yours
- Part-time or gig worker — employer typically doesn’t offer
- Subsidy-eligible income: under ~$60K single / $120K family of four, subsidies often make marketplace cheaper than even subsidized employer plans
- Early retiree before Medicare: marketplace bridges 50s-65 gap
Subsidies you may not know about
Premium tax credits (subsidies) are now available up to higher income levels through 2025 (and likely longer). A family of four earning $120K can still qualify for meaningful subsidies. Get a marketplace quote even if you think you earn too much.
How to compare an employer plan to a marketplace plan
- Total annual cost: employer premium contribution + your share, vs. marketplace premium after subsidies
- Deductibles + max out-of-pocket: what’s your worst-case year cost?
- Network: are your doctors in-network?
- Formulary: are your prescriptions covered?
- HSA-eligibility: many marketplace plans qualify; some employer plans don’t
- Family vs. individual structure: marketplace plans price per person; employer plans often have fixed family tiers
Open enrollment
- Employer: typically October-December, sometimes shorter window
- ACA marketplace: November 1 - January 15 (varies slightly by state)
- Special enrollment periods: triggered by qualifying life events (job loss, marriage, birth, move)
Outside these windows, you generally can’t change plans unless you have a qualifying event.
What to do if you have access to both
If you’re offered employer coverage and want to use the marketplace instead:
- You can decline employer coverage
- You can apply for marketplace subsidies — BUT if your employer offer is “affordable” by ACA definition, you’re not eligible for marketplace subsidies
- Run the math both ways before deciding
