Turning 65 guidance
A clear timeline of what to do and when, so you understand your deadlines and reduce the risk of a late-enrollment penalty.
Find your situation, find your window
This page covers two different worlds. Marketplace coverage runs on one calendar, Medicare runs on another, and the most common mistake we see is someone assuming they are on the wrong one. Find the row that sounds like you.
| Where you are | Your window | What that means |
|---|---|---|
| Under 65, buying your own coverage | Nov 1 to Dec 15 | Open enrollment for a January 1 start. Outside it you need a qualifying life event to get in. |
| Turning 65 soon | The 7 months around your birthday | Your Initial Enrollment Period is personal to you, not a date on the calendar. Our guide to when to enroll in Medicare walks through the timing. |
| Already on Medicare | Oct 15 to Dec 7 | Annual Enrollment, your yearly chance to change Advantage or Part D plans for January 1. Plans change every year, so a plan that fit last year may not this year. |
| Working past 65 with employer coverage | Depends on the employer | With fewer than 20 employees Medicare generally pays first, so most people in that spot still enroll at 65. Worth a call before you decide to wait. |
| Just lost coverage from a job | Marketplace 60 days · Part B 8 months | On the Marketplace it is a qualifying life event with a window that generally runs 60 days before to 60 days after the loss. If you are 65 or older, Medicare Part B has a separate special enrollment period of up to eight months after the employment or coverage ends. COBRA does not extend the Medicare clock. |
| Self-employed | Nov 1 to Dec 15 | Same window as everyone else. The part that is different for you is estimating a variable income, which is what decides your cost. |
Not sure which row is yours? That is a two-minute phone call, and it is the call worth making before you shop anything.
The enrollment dates that matter.
Health coverage runs on deadlines, and one of them moved. Marketplace open enrollment now runs November 1 through December 15, a month earlier than the January 15 deadline South Carolina had in past years, with coverage starting January 1. Medicare’s annual enrollment period is unchanged: October 15 through December 7 each year.
Missed a window? You may still qualify for a special enrollment period after life events like losing job coverage, moving, getting married, or having a baby. Call us and we’ll tell you straight whether you have an option right now or what the next window is.
- Marketplace open enrollment: November 1 to December 15
- Medicare annual enrollment: October 15 to December 7
- Special enrollment periods after qualifying life events
- Our guidance costs you nothing, plan prices are identical with or without an agent

Your income estimate is the number that decides your cost
For Marketplace coverage, the premium tax credit is usually the difference between a plan that works and a plan nobody can afford. Two rule changes now in effect make the estimate behind that credit matter more than it used to.
The first is the return of the income cliff. The temporary rules that extended help above 400 percent of the federal poverty level expired at the end of 2025. For 2026 and 2027 coverage that line is hard again: under it you may qualify for a credit, and over it by even a small amount you get nothing. There is no gradual phase-out to cushion the landing.
The second is repayment. The old caps on paying back excess credit are gone. If you take the credit in advance and your actual income lands higher than you estimated, you repay the full difference at tax time rather than a limited portion of it.
Put those together and a modest, ordinary change during the year, a raise, a good quarter, a spouse picking up hours, a retirement account conversion, can move what you owe by a meaningful amount. This hits self-employed and commission-based households hardest, because their income is genuinely hard to predict in November for the following year.
None of this means you should guess low to protect a credit. That is the version that produces the April surprise. It means the estimate deserves an actual conversation, and that you should tell us when your income changes mid-year so the credit can be adjusted while there is still time. We cannot tell you what you will qualify for until we look at your numbers, and eligibility depends on your household size, income, and what coverage you are offered elsewhere. What we can do is walk through it with you before you enroll rather than after.
For more background, our guides cover how subsidy eligibility works in South Carolina and how the credits and repayment rules interact at tax time.
- We look at your household size and expected income before you pick a plan
- Plans compared on total cost, not just the monthly premium after a credit
- Mid-year income changes reported so the credit adjusts in time
- Straight answers about where you fall, including when the answer is no credit
Estimate it, do not guess it
The households that get hurt are the ones that picked a number in November and never looked at it again. Ten minutes on the estimate up front is worth more than any plan comparison we can run for you.
Health and Medicare questions, answered
When can I enroll in health insurance in South Carolina?
Marketplace open enrollment runs November 1 through December 15 for South Carolina, with coverage starting January 1. Note that this deadline moved earlier: it ran through January 15 in past years, so do not go by memory. Outside that window, you may qualify for a special enrollment period after events like losing job coverage, moving, getting married, or having a baby. Medicare's annual enrollment period is unchanged at October 15 through December 7.
What happens if my income goes over the subsidy limit?
For 2026 and 2027 coverage the 400 percent of federal poverty level line is a hard cutoff again, so going over it means no premium tax credit at all rather than a smaller one. The caps on repaying excess credit are also gone, so if you take a credit in advance and earn more than you estimated, you repay the full difference at tax time. We cannot tell you what you qualify for without looking at your household size and income, but we will walk through the estimate with you before you enroll, and you can tell us mid-year if your income changes so it can be adjusted in time.
Does it cost anything to use Griffin Insurance Agency for health or Medicare plans?
No. Our help costs you nothing. Plan prices are set by the carriers and are the same whether you enroll through an agent or on your own. The difference is you get a local team to compare options, check provider networks, and help at claim time.
What's the difference between Medicare Supplement and Medicare Advantage?
Medicare Supplement (Medigap) works alongside Original Medicare, helping pay deductibles and coinsurance, with broad access to any provider that accepts Medicare. Medicare Advantage replaces how you receive benefits, bundling coverage into one plan, often with drug, dental, and vision extras but with provider networks. The right fit depends on your doctors, prescriptions, and budget, and we compare both with you.
Can I get health coverage outside open enrollment?
Possibly. Qualifying life events like losing employer coverage, moving to a new area, marriage, or a new baby open a special enrollment period, usually lasting 60 days from the event. Call us at 803-848-0089 and we’ll check your options right away.
