Medicare Planning
In short
Medicare arrives with a deadline, a choice that is easier to make than to undo, and a premium set partly by a tax return from two years earlier. The useful work happens before all three.
Medicare is federal health insurance most people become eligible for at 65, and it asks for several decisions: when to sign up, whether to take Original Medicare with a supplement or a Medicare Advantage plan, how to cover prescriptions, and how to manage the income that sets your premium. Timing is the unforgiving one, because Part B and Part D late enrollment penalties are added to your premium and, for most people, stay there.
Original Medicare or Medicare Advantage
Once you have Parts A and B, you choose how to take them. Original Medicare works with any doctor who takes Medicare, and you add a drug plan and a Medigap supplement. A Medicare Advantage plan from a private company usually costs less each month and includes drug coverage, in exchange for a network and approvals.
The way back is what makes this more than a yearly preference. Federal law gives you one six-month Medigap open enrollment period, starting the first month you are 65 and enrolled in Part B, when an insurer cannot refuse you or charge more for your health. After it closes, in most states it can do both.
The seven-month sign-up window
Your Initial Enrollment Period runs from three months before the month you turn 65 to three months after it. Miss it without other qualifying coverage and penalties are added to your Part B and Part D premiums. They grow the longer you wait and, for most people, last as long as you hold the coverage. The Part D penalty applies once you go 63 days or more without creditable drug coverage, meaning coverage expected to pay, on average, at least as much as Medicare’s standard drug coverage.
If you are still working at 65 with qualifying employer coverage, a Special Enrollment Period runs for eight months after the job or the coverage ends, and signing up within it avoids the Part B penalty. Ask your employer to confirm in writing that its drug coverage is creditable, and keep the letter.
IRMAA, and the tax return from two years ago
Above a certain income, Part B and Part D cost more: the income-related monthly adjustment amount, or IRMAA. Social Security sets it from the tax return you filed two years earlier, so your premium at 65 depends on the year you turned 63, and income just over a threshold raises it for a full year.
That puts Medicare inside decisions you make in your early sixties: how much to convert to a Roth, which account to draw from, when to realize a gain. If a life-changing event has lowered your income, Medicare notes that you can ask Social Security to reduce the adjustment.
Start with the calendar
We start with the calendar: your Initial Enrollment Period, set beside the dates for Social Security and any employer coverage you are leaving. Many costly Medicare mistakes are timing mistakes, and timing is the easiest part to get right in advance.
Then we plan the income that will set your premiums. For the coverage choice itself, Florida SHINE, run by the state Department of Elder Affairs, offers free, unbiased counseling not connected to any insurance company, and Medicare.gov publishes each year’s figures.
Who this is for
You are approaching 65 and have never chosen health coverage without an employer doing most of the work.
You are retiring before 65 and need coverage until Medicare starts.
You are still working at 65 with employer coverage and are not sure whether to sign up or wait.
You are weighing Roth conversions and want to know what they would do to your Medicare premium.
Worth thinking about
What month does your Initial Enrollment Period open, and is it written down?
If you retire before 65, where will your coverage come from, and what will it cost?
If you are working at 65, does your employer coverage let you wait, and what happens to your Health Savings Account if you enroll?
What will your taxable income be in the years that set your first premiums?
Do your doctors and your travel plans matter more to you than a lower monthly premium?
Common questions
Do I have to sign up for Medicare at 65?
Not always. If you or your spouse is still working and covered by that employer’s plan, you may be able to delay Part B without a penalty; confirm it with your employer before you rely on it. Because Part A is premium-free for most people, many take it at 65 and wait on Part B.
Which is better, a Medicare Advantage plan or Original Medicare with a supplement?
Neither, in general. It depends on your doctors, your travel and how you weigh the monthly premium against costs when you need care. Decide with the way back in mind: after your one-time six-month Medigap open enrollment period, an insurer in most states can decline you or charge more based on your health.
What is IRMAA, and can anything be done about it?
It is an extra charge on Part B and Part D premiums above a certain income, set from your tax return two years earlier. You cannot change a filed return, but you can plan the years ahead, and after a life-changing event you can ask Social Security to lower the adjustment.
We want to retire at 62. What do we do about health insurance until 65?
Something has to bridge the gap: a retiree plan, a spouse’s plan, COBRA or a Marketplace policy. On the Marketplace the premium tax credit depends on household income, which can pull against Roth conversions in the same low-income years. It is worth modeling before you give notice.
What does your help with Medicare involve?
We work on how Medicare fits the rest of your plan: the dates, the penalties that follow them, the trade-off between the two routes, and what your income does to your premiums. This is planning education rather than a plan comparison. For the coverage choice itself, Florida SHINE offers free and unbiased counseling.
