COBRA vs Marketplace: choosing health coverage after leaving a job

Leaving a job to work for yourself usually means leaving employer health coverage. The two main options are continuing that coverage through COBRA or buying a plan on the Health Insurance Marketplace. The right choice depends on cost, your health needs and your expected income. The timing rules matter just as much, because a wrong move can leave you waiting for the next open enrollment.

What COBRA is

COBRA lets many people keep their employer's group health plan for a limited time after leaving a job. You keep the same insurer, network and benefits. HealthCare.gov's COBRA guidance refers to coverage commonly lasting up to 18 months, and you usually pay the full premium yourself, often including a small administrative charge, because your employer generally stops contributing.

What a Marketplace plan is

The Marketplace offers individual health plans, with savings based on your expected household income for the coverage year. For the self-employed, HealthCare.gov asks for the income you expect from your business after expenses. Depending on that estimate, you may qualify for a premium tax credit that lowers your monthly premium.

Comparing cost

  1. Find your monthly COBRA cost on your election notice.
  2. Estimate your self-employment income for the year; see estimating income for the Marketplace.
  3. Preview Marketplace plans and savings.
  4. Compare premiums plus expected out-of-pocket costs: deductibles, copays and coinsurance.

Many new business owners find Marketplace plans cheaper, particularly in the first year when business income may be modest.

Comparing coverage

The timing rules

HealthCare.gov explains that losing job-based coverage, including when you leave a job, generally qualifies you for a Special Enrollment Period. You can usually enrol if you lost coverage in the past 60 days or expect to lose it in the next 60 days.

If you choose COBRA, switching later is limited:

This makes the initial decision important.

A practical approach

After you enrol

Report income changes to the Marketplace promptly, keep your coverage documents, and plan your next open enrollment review. Self-employed people may be able to deduct premiums; see the self-employed health insurance deduction.

Planning the exit

Health coverage is one item in the checklist for leaving your job. Get COBRA and Marketplace quotes before you resign, so the decision is ready when your coverage ends. The guide to Marketplace health insurance explains plan types.

Questions to ask before you decide

Write the answers down and compare total expected cost, not only the monthly premium.

Revisit each year

Your income and health needs change. Review your coverage during each open enrollment period and update your income estimate on the Marketplace when it changes.

Compare COBRA's full cost and continuity with Marketplace prices and savings based on your expected income, check doctors and drugs, and decide within the 60-day Special Enrollment Period, because voluntarily dropping COBRA later does not reopen enrollment.

Questions people ask

How long can COBRA last?

Often up to 18 months after leaving a job, and longer in some situations. Check your election notice.

Can I switch from COBRA to a Marketplace plan later?

During open enrollment, yes, for any reason. Outside open enrollment, HealthCare.gov says you can switch if your COBRA is running out, if you must start paying the full cost because your former employer stops contributing or a subsidy ends, or within 60 days of losing job-based coverage. Voluntarily dropping COBRA does not qualify.

Can I get premium tax credits with COBRA?

Generally, savings on Marketplace plans are not available for COBRA coverage. Enrolling in COBRA can also affect whether you can get Marketplace savings during that time.

What if I have a big medical bill coming up?

COBRA may make sense if you have met your deductible or are mid-treatment with doctors outside Marketplace networks.
