The direct answer
Direct answer — ACA to Medicare · North Carolina · 2026
When you turn 65 and become eligible for Medicare, your ACA premium tax credits end — by law. Your Marketplace plan does not cancel automatically. You need to enroll in Medicare during your 7-month Initial Enrollment Period, then actively cancel your HealthCare.gov plan so the end date lines up with your Medicare start date. Cancel too early and you have a coverage gap. Cancel too late and you owe back the subsidies you received after becoming Medicare-eligible. If you delay Medicare enrollment without qualifying employer coverage, you face a 10% Part B late enrollment penalty for every 12 months you delayed — added to your premium for life. ACA coverage is not considered creditable coverage for Medicare purposes.
THE BROKER'S ANSWER
This is the transition I handle most often, and the one where the most money is at stake if the timing is off. The biggest thing people miss: your ACA subsidies don’t end when you enroll in Medicare — they end when you become eligible for premium-free Part A, which for most people is the first day of your birthday month. If you keep collecting subsidies past that date, the IRS will claw them back on your tax return. The second thing people miss: your Marketplace plan isn’t creditable coverage for Medicare Part B, so every month you stay on it past eligibility adds to a lifetime penalty. I handle both ACA and Medicare, so I coordinate the exact cancel date, the Medicare enrollment, and the plan selection in one call — no gap, no penalty, no surprise tax bill.

The timeline
How does the ACA-to-Medicare transition actually work?
If born on the 1st of the month, Medicare eligibility begins the prior month. If you or your spouse have active employer group coverage (20+ employees), different rules apply — you may be able to delay Medicare without penalty. COBRA and retiree coverage do not qualify.

Every mistake below costs real money — either as a lifetime penalty, a tax repayment, or a coverage gap that hits when you need care most.
Last reviewed: 2026-07-01 · Robert Simm, Licensed NC Health Insurance Broker, NPN #10447418
Mistake 01 Subsidies
Keeping your Marketplace plan after becoming Medicare-eligible and owing back subsidies.
Why it hurtsACA premium tax credits end the month you become eligible for premium-free Medicare Part A — whether or not you’ve actually enrolled in Medicare. If you keep collecting subsidies past that date, the IRS requires you to repay every dollar of excess Advance Premium Tax Credit on your next tax return. For someone receiving $500/month in subsidies, even a 3-month delay means $1,500 owed at tax time.
What to doSchedule your Marketplace plan cancellation on HealthCare.gov to end the last day of the month before your Medicare start date. If your birthday is in October, cancel ACA effective September 30, with Medicare starting October 1.
Mistake 02 Penalty
Thinking your ACA plan counts as “creditable coverage” for delaying Medicare Part B.
Why it hurtsACA Marketplace plans, COBRA, and retiree health plans are NOT considered creditable coverage for Medicare Part B enrollment purposes. The only valid exception is active employer group coverage from an employer with 20+ employees. Every 12-month period you delay Part B without a valid exception adds a permanent 10% surcharge to your Part B premium. A 2-year delay on the 2026 premium of $202.90 means paying $243.48/month for the rest of your life.
What to doEnroll in Part B during your Initial Enrollment Period, even if you feel healthy and your ACA plan seems fine. The penalty is permanent and there is no waiver.
Mistake 03 Gap
Canceling your ACA plan before Medicare coverage actually starts.
Why it hurtsIf you enroll in Medicare during the last 3 months of your IEP (after your birthday month), Part B coverage doesn’t start immediately — it can be delayed 1–3 months. If you already canceled your Marketplace plan, you’re uninsured during the gap. One ER visit during that window could cost tens of thousands of dollars.
What to doEnroll in Medicare during the first 3 months of your IEP (before your birthday month) so coverage starts the 1st of your birthday month. Then cancel your ACA plan to end the last day of the prior month. No gap.
Mistake 04 Medigap
Missing the 6-month Medigap Open Enrollment window.
Why it hurtsFor 6 months starting when your Part B begins, you can buy any Medigap plan in North Carolina with guaranteed issue — no health questions, no denial, no pricing based on conditions. After that window closes, NC Medigap insurers can underwrite you. If you develop a health condition during those 6 months, you may be denied supplemental coverage entirely.
What to doEven if you choose Medicare Advantage initially, understand that the Medigap door closes 6 months after Part B starts. If you want to keep Original Medicare + Medigap as an option, decide before the window closes. Call me to compare both paths.
Mistake 05 Spouse
Accidentally canceling your spouse’s ACA coverage when you cancel yours.
Why it hurtsIf both spouses are on the same Marketplace application and the older spouse turns 65 first, clicking “End all coverage” on HealthCare.gov terminates the younger spouse’s plan too. The younger spouse then needs a Special Enrollment Period to re-enroll, and if the household income changes (because the Medicare-eligible spouse is no longer on the application), the subsidy amount recalculates — sometimes significantly.
What to doCall the Marketplace at 800-318-2596 or work with a broker to remove only the turning-65 spouse from the application. Do not use the “End all coverage” button. Update the household income on the remaining spouse’s application so the subsidy is recalculated correctly.
The comparison
ACA Marketplace coverage vs. Medicare — what changes when you turn 65?
| Feature | Your ACA plan (before 65) | Medicare (after 65) |
|---|---|---|
| Premium assistance | Premium tax credits based on income | No subsidies. Part B is $202.90/mo (2026). IRMAA surcharges for high earners. |
| Prescription drugs | Included in your plan | Separate Part D plan required (or included in MA). $2,100 out-of-pocket cap in 2026. |
| Out-of-pocket max | Required by law ($9,200 individual / $18,400 family for 2026) | Original Medicare has NO out-of-pocket cap. MA plans cap at $9,350 in-network. |
| Doctor networks | Carrier-specific HMO/PPO networks | Original Medicare: any doctor who accepts Medicare. MA: plan-specific network. |
| Dental / Vision / Hearing | Pediatric dental required; adult dental/vision varies | Not covered by Original Medicare. Often included in MA plans. |
| Annual re-shopping | OEP: Nov 1 – Jan 15 | AEP: Oct 15 – Dec 7 |
⚠ Subsidy Repayment Warning
If you continue receiving ACA premium tax credits after you become eligible for premium-free Medicare Part A, the IRS will require you to repay the full amount of excess subsidies on your next tax return. Unlike income-based subsidy true-ups, there is no repayment cap for subsidies received while Medicare-eligible — you owe it all back. If you turned 65 mid-year and are still on a Marketplace plan, call now to coordinate the transition before tax season.
💡 Broker Tip · Born on the 1st?
If your birthday is on the 1st of any month, your Medicare eligibility begins one month earlier than you’d expect. Born July 1? Medicare eligibility starts June 1, and your ACA subsidies end June 1. This catches people off guard every month. I check your exact birth date and build the timeline backward from there so nothing slips.
Common questions
Frequently asked questions
Can I keep my ACA plan after I turn 65?
Technically yes, but you’ll lose all premium tax credits the month you become eligible for premium-free Part A. That means you’d pay full price for your Marketplace plan — typically $400–$700/month in North Carolina. For most people, Medicare (even with Part B at $202.90/month plus a supplement or MA plan) is significantly cheaper.
What if I’m not eligible for premium-free Part A?
If you haven’t worked 40 qualifying quarters (10 years), you may have to pay a Part A premium. In that case, you can keep your Marketplace plan and continue receiving subsidies — your subsidy eligibility only ends when you qualify for premium-free Part A. Talk to a broker before deciding, because buying Part A may still be cheaper than staying on ACA full-price.
My spouse is younger than 65. What happens to their coverage?
Your spouse can stay on a Marketplace plan after you move to Medicare. You’ll need to update the HealthCare.gov application to remove yourself without canceling their coverage. The household income will be recalculated for subsidy purposes — since you’re no longer on the application, the subsidy for your spouse may change. I coordinate both sides in one call.
Do I need to sign up for Part D if I choose Medicare Advantage?
Most Medicare Advantage plans include Part D drug coverage (called MA-PD plans). If yours does, you don’t need a separate Part D plan. If you choose Original Medicare + Medigap, you should add a standalone Part D plan during your IEP to avoid the Part D late enrollment penalty, which is 1% of the national base premium for every month you delayed.
Why should I use a broker who handles both ACA and Medicare?
Because the transition has three moving parts that need to be coordinated: the ACA cancelation date, the Medicare enrollment date, and the plan selection. A broker who only handles Medicare can’t help you cancel your Marketplace plan or coordinate your spouse’s coverage. A broker who only handles ACA can’t compare Medicare Advantage, Medigap, or Part D plans. I’m licensed for both and handle the whole transition in one call. (828) 761-3326
One broker, both products
Why does it matter to have the same broker for ACA and Medicare?
Because most people who call a Medicare hotline get someone who has never logged into HealthCare.gov. And most ACA Navigators have never enrolled someone in Medicare Advantage or Medigap. The transition from one to the other is where the mistakes happen — wrong cancel date, coverage gap, subsidy repayment, missed Medigap window. I handle both sides, so nothing falls between the cracks. Same broker, same phone number, before and after 65.
