This is the last of the seven, and it is the one that lands hardest on people who did everything else right.
He retired in April after a good final year. Sold some stock to fund the transition, took a deferred payout, closed out the business. Big year on paper, deliberately so.
The following January a notice arrives from Social Security explaining that his Medicare premium will be roughly triple what he expected. Not because of anything he did this year. Because of what he earned two years ago, in the last full year he was working.
He is being billed on income he no longer has.
Why is my Medicare premium so much higher than the standard amount?
Because Part B premiums are income-related, and the income they use is old.
The surcharge is called the Income-Related Monthly Adjustment Amount. Most people never encounter it. As the Centers for Medicare and Medicaid Services notes in its 2026 figures, these adjustments "affect roughly 8% of people with Medicare Part B."
That 8 percent is not a random slice. It is disproportionately made up of business owners, professionals, and households who had one unusually large year right before retiring, which is precisely the group this series has been about all week.
The 2026 numbers
Below $109,000 in modified adjusted gross income for an individual, or $218,000 filing jointly, there is no adjustment at all and the premium is the standard $202.90. Above those lines it steps up, and the steps are not small.
- Above $109,000 single or $218,000 joint: $284.10 a month
- Above $137,000 single or $274,000 joint: $405.80 a month
- Above $171,000 single or $342,000 joint: $527.50 a month
- Above $205,000 single or $410,000 joint: $649.20 a month
- At $500,000 single or $750,000 joint and above: $689.90 a month
Every figure there is from the CMS fact sheet linked above.
Two things to notice. These are per person, so a married couple both on Medicare can be paying two of these. And the brackets are cliffs, not slopes. A dollar over a threshold moves you to the next tier in full.
The part that makes it feel unfair
The income used is from your tax return two years back. In 2026, that generally means your 2024 return.
For someone whose income is steady, this is a rounding detail. For someone who just retired, it is the whole problem. The year they are being billed on is, almost by definition, the biggest year they will ever have, because it contained the final salary, the business sale, the deferred compensation, the account restructuring that funded the retirement.
The surcharge shows up exactly when the income to pay it has gone away.
The form nobody mentions
Here is the good news, and it is genuinely good.
Social Security will reconsider using your current income instead of the old return, if the drop was caused by a specific life-changing event. Retiring, described as work stoppage or work reduction, is on that list.
The form is SSA-44, titled Medicare Income-Related Monthly Adjustment Amount, Life-Changing Event. You can find it on ssa.gov by that number.
A few things worth knowing about how it works:
You can file it based on income you expect, not only income already earned
Social Security allows you to report a reduction that has already happened or one you anticipate this year or next as a result of the event. You do not have to wait two more years for the tax returns to catch up.
The event has to line up with the tax year
The life-changing event must fall in the same year as, or an earlier year than, the tax year you are asking them to use. Retiring in April and asking them to use that year's income works. The sequence matters.
Bring documentation
A letter from the employer confirming the retirement date, or comparable proof of the event, plus an estimate of the new income. This is a paperwork exercise, not an argument.
This is a request for a new decision, not an appeal
A useful distinction. You are not disputing that the old number was right. You are telling them the situation changed and asking them to use the current one.
The planning version of this
The best outcome is not winning the reconsideration. It is knowing about the cliffs before the big year happens.
Because the brackets are cliffs, the difference between landing just under a threshold and just over it is the same premium for an entire year. When a household has any control over the timing of income, and many of the households in this series do, that control is worth something real.
A business sale that straddles a year end. A Roth conversion sized to a threshold rather than to a round number. A capital gain taken in two pieces instead of one. None of that is exotic and all of it has to happen before the year closes, not after the notice arrives.
From the conversations our advisors have, this is the single most common place where someone says they wish they had made one phone call twelve months earlier. Not because anything went wrong, but because a decision that would have been easy in October became impossible in February.
That is the seventh door
Seven people this week. A business owner whose plan was quietly paying second. A woman whose clock started the day her job ended. A veteran told he did not need Part B. A public sector retiree with excellent coverage that assumed something nobody mentioned. A wife nobody asked about. A woman who found the door had locked behind her. And a man billed for money he no longer had.
Not one of them was careless. Every single one of them was doing what a sensible person would do.
That is the thing worth taking from the week. These are not traps for people who are not paying attention. They are traps for people who are paying attention to the wrong thing, because nobody ever told them which thing mattered.
If any of these seven sounded like you, or like someone at your dinner table, that is worth a conversation before it is worth a form. Our advisors at American Retirement Advisors work through all seven of these regularly, and there is no cost to you for the conversation.
This is the final part of Seven Ways In. Start at the beginning with part one.
