Medicare vs. Marketplace: Which One Are You Supposed to Have?
Viva Insurance Group · Updated July 2026 · 4 min read
These are two completely separate systems, and the rule for which one you belong in is simpler than it looks: it's almost entirely about age 65.
The simple rule
- Under 65, no employer coverage: the Marketplace is your system. Subsidies lower the premium based on income.
- 65 or older (or on disability 24+ months): Medicare is your system, even if you like your Marketplace plan.
The trap: staying on a Marketplace plan past 65
This is where people get hurt. Once you're eligible for Medicare:
- Your Marketplace subsidy ends. Keeping the plan means paying full price, and any subsidy paid after eligibility may have to be repaid at tax time.
- Medicare late penalties start accruing. Part B costs 10% more per year late, for life. The Marketplace plan doesn't count as "creditable coverage" that protects you.
In plain English: the Marketplace doesn't kick you out at 65, it just quietly gets expensive and starts a penalty clock. The move to Medicare is on you.
The handoff, step by step
- ✓3 months before 65: enroll in Medicare Parts A and B (see our turning-65 checklist).
- ✓Pick your Medicare path: Advantage or Supplement, with your doctor list in hand.
- ✓Then cancel the Marketplace plan effective the day Medicare starts, not before (no gap), not after (no double-paying).
Mixed households
One spouse turning 65, the other 58? Completely normal: the older spouse moves to Medicare, the younger stays on a Marketplace plan, and the household subsidy gets recalculated for the smaller plan. We handle both sides of that transition in one conversation.
Close to 65 and on a Marketplace plan? Let's time your handoff so nothing lapses and no penalty starts.
