Real questions from real calls : and the reasoning behind the answers.
Most calls that end up here don’t start with the word IRMAA. They start with someone pricing out a Medicare Advantage plan or a Supplement, and somewhere in the middle of that, they hit a number that doesn’t match what they were quoted.
“I was gonna go at 65, but then when I started looking at what my healthcare coverage is gonna cost me, just in premiums, you know, you go four or five each and then you got your supplement, it’s probably 200.”
That’s usually the moment I explain the second bill nobody warned them about. It’s called IRMAA, the Income-Related Monthly Adjustment Amount, and it isn’t a plan feature, a carrier fee, or anything I’m selling. It’s a surcharge Medicare itself adds to your Part B premium, and sometimes your Part D premium, based on what you earned two years ago. It has nothing to do with which plan you pick. It has everything to do with a tax return you may have already forgotten about.

Why did my Medicare premium go up because of my income?
The confusion almost always starts the same way: someone assumes the higher number is a billing mistake, or a scare tactic from whoever mailed them a postcard.
“I’ve seen all these people jumping on their Facebook, trying to… I’m telling you, just seem like the person that I need to be able to trust. I get letters every day.”
So I separate the two things right away. There’s the noise, the Facebook ads, the mailers, the calls from numbers nobody recognizes, and there’s the actual mechanism, which is quiet, automatic, and comes straight from Social Security, not from any insurance company. If your income crossed a certain level on a tax return from two years back, Medicare adds a surcharge to your Part B premium. High enough income, and your Part D premium gets one too. It shows up whether you choose a Medicare Advantage plan or a Supplement. Nobody is trying to sell you out of it, because there’s nothing to sell, it’s built into Medicare itself.
What income level actually increases Medicare premiums?
I’m going to be careful here, because the exact dollar thresholds move most years, and I don’t want to hand you a number that’s already stale by the time you read this. What I can tell you is the shape of it, because the shape doesn’t change:
- Medicare looks at your Modified Adjusted Gross Income from two years before the year you’re paying for. Your premium this year is tied to a tax return you may not remember filing.
- It’s tiered, not a cliff. Cross the first line and you pay a bit more. Cross further lines and you pay progressively more, on both Part B and Part D.
- The threshold is different for single filers versus married filing jointly. A couple filing together generally has more room before the surcharge kicks in than a single filer at the same income.
- It applies no matter which plan you choose. Advantage, Supplement, doesn’t matter. This sits above the plan layer entirely.
“every year they get to look at my two years ago AGI… I’m not stuck with this $15,000 for the rest of my life… Is that correct?”
That question gets to the heart of it. No, you’re not stuck. It’s recalculated every year off a moving two-year-old number, which means a high-income year eventually rolls out of the window on its own, and a lower-income year eventually rolls in. The surcharge is never permanent by default, but it also isn’t optional, and it isn’t waived just because your income has since changed, unless you go ask for that specifically.
- 1Income two years ago?Your premium runs off that year, not this one.
- 2A qualifying life event?Only specific events unlock a recalculation.
- 3Roth conversion or big sale?The two most common self-inflicted triggers.
- 4Filing status changed?Widowhood can flip you to a lower threshold overnight.
- 5Medicare start vs. income year?Retiring mid-year can split one year into two rates.
What I ask first
Before I tell anyone whether IRMAA applies to them, or what to do about it, I need five answers. These aren’t small talk, each one changes what I’d tell you to do next.
- What was your income two years ago, and is this year genuinely different? The lookback is the whole ballgame. A number from two tax returns ago is doing the work, not your current bank balance.
- Is there a life-changing event on the calendar, retirement, a layoff, a marriage, a divorce, a spouse’s death? Social Security recognizes a specific short list of events that let you ask for a recalculation off a more current number instead of the old one. Most income drops don’t qualify. These specific ones do.
- Are you converting retirement money to a Roth, or about to sell something that creates a large one-time gain? Roth conversions and asset sales are the two most common reasons someone lands in a higher tier without meaning to, and the two most controllable, if you plan the timing.
- Are you filing single or married, and did that change recently? Widowhood in particular can push someone from a joint threshold to a single one, right when their income hasn’t changed at all.
- When exactly does your Medicare start, relative to the income year in question? Retiring mid-year sometimes means one income figure applies for part of the year and a lower one kicks in the next, which is why I’ve had clients pay a surcharge for one month and the standard rate the next.
People often mix up three different clocks on this: when Medicare starts, when full retirement age hits for Social Security, and when the income year that determines IRMAA gets locked in. They’re related, but they’re not the same clock, and mixing them up is how someone ends up paying a surcharge they could have avoided by retiring a couple months earlier or later.
See where you land. If you would rather just talk it through with someone who does this every day, Most people can sort the direction quickly once the doctors, drugs, budget, and timing are on the table.
Where these conversations usually land
Once I’ve got those five answers, the conversation about IRMAA itself tends to go one of three ways.
Path one, pay it, because there’s genuinely nothing to do. If the income was from something ordinary, wages, standard investment income, nothing you’d undo, and no qualifying event applies, the honest answer is that you pay the surcharge for the year it applies and let the two-year window roll it off on its own. The trade: you accept a known cost now instead of spending energy fighting something that isn’t fightable.
Path two, file the one-time adjustment. If retirement, a spouse’s death, or another recognized event changed your income, there’s a form for exactly this. You report the change and ask Social Security to use a more current estimate instead of the two-year-old number. The trade: paperwork and a wait, in exchange for a premium that reflects your actual current life instead of a stale tax return.
Path three, manage the income event before it happens. This is for people who see a Roth conversion, a property sale, or a big withdrawal coming and still have room to time it. Spreading a conversion over several years, or doing it in a lower-income year, can keep you out of a higher tier altogether. The trade: you give up some flexibility on when you do the financial move, in exchange for not manufacturing a surcharge you didn’t need to create.
Why I lean toward planning ahead of the tax return, not after
If someone has any control over the timing, a Roth conversion, a large withdrawal, the exact month they retire, I lean toward dealing with IRMAA before the income event happens, not after. Here’s the reasoning.
The life-changing-event form only works for events Social Security actually recognizes. A big one-time capital gain from selling stock, or a large Roth conversion, generally isn’t on that list. Once that income is on a tax return, there’s no form that undoes it. You simply pay the higher tier for the year the lookback lands on. I had a client with exactly this shape of problem: an unexpected reported gain from an inherited-stock sale pushed him into a surcharge tier, and the one-time exemption he’d normally use didn’t apply because a capital gain isn’t a qualifying life event. He kept that exemption in his pocket for something else instead.
The cost of getting this backwards isn’t catastrophic, a surcharge tier is a real number, but it’s not going to bankrupt anyone the way an uncovered hospital stay could. But it’s an avoidable cost, and avoidable costs are worth avoiding, especially for people already juggling 401(k) and 403(b) transitions at the same time they’re figuring out Medicare. A couple weighing a large retirement-account conversion near retirement isn’t wrong to want the conversion. They’re just better off spreading it, or timing it around their Medicare start, than doing it in one lump sum and discovering the surcharge afterward.
When I’d tell you the opposite, don’t bother managing around it
This is the part most people don’t hear from whoever sold them the postcard, so I’ll say it plainly: sometimes fighting IRMAA is a waste of your time, and I’ll tell someone that directly.
When you’re going to be in a high tier every single year regardless. Some of my clients have income that puts them well above every threshold as a matter of course, year after year, whether or not they do anything unusual. For someone in that position, restructuring finances to shave a Medicare surcharge is solving the wrong problem. The surcharge is a rounding error against their overall income, and the energy is better spent elsewhere.
When the tax benefit of the move outweighs one year of surcharge. A Roth conversion that saves meaningfully on taxes over the next twenty years can be worth one elevated tier for a year or two. I don’t want anyone talking themselves out of a genuinely good financial move because they’re afraid of a comparatively small Medicare add-on. The math should decide it, not the fear of the letter.
When the event isn’t really controllable. Not every income spike is a choice. A required distribution, an inherited account payout, a one-time settlement, these aren’t things you engineer around easily, and trying to can cost more in flexibility than the surcharge itself. In those cases, paying it and letting the two-year window pass is the right answer, not a consolation prize.
When you’re already saving the one-time exemption for something bigger. That life-changing-event form is generally a use-it-when-it-matters tool, not something to spend on a minor bump. I’ve had clients deliberately hold onto it after one event, betting there’s a larger one coming where it’ll matter more.
Which side of that line are you on?
That is exactly the question a short Medicare conversation settles. You get me, not a call center.
What surprises people most about this
Two things catch almost everyone off guard.
The first is the lookback itself. People assume their premium reflects their income right now, the modest fixed income they’re living on in retirement. It doesn’t. It reflects a tax return from two years earlier, back when they were often still working full salary. That mismatch is exactly what’s behind the question I hear over and over, about being permanently “stuck” with an old number. They aren’t. It just takes two years to catch up.
The second is that it has nothing to do with the plan they end up choosing. People spend weeks comparing a Medicare Advantage plan against a Supplement, assuming the surcharge is somehow tied to that decision. It isn’t. You can pick the lowest-cost plan available in your area and still owe the exact same surcharge, because it’s attached to Part B and Part D themselves, not to whatever plan sits on top of them. I’ve had people bring me a letter of adequate coverage from an employer, trying to sort out a completely separate penalty question, “I’m thinking about getting that letter of adequate coverage from his employer and filing it with the Social Security Department”, and we still have to have the separate IRMAA conversation, because late-enrollment penalties and income surcharges don’t overlap even though they land on the same bill.
Where do you go from here?
If you’re staring at a Medicare premium that’s higher than the number you were quoted, the first question isn’t which plan to buy. It’s whether that gap is IRMAA, and if it is, which of the three paths above actually fits your income, pay it, adjust it, or plan around it before it happens.
“I appreciate you all double-checking and coming back and hailing at me to make this appointment. I really do. Because I don’t know anything about this kind of stuff.”
That’s the more common feeling than embarrassment, in my experience, relief that someone will just sit down and go through the actual numbers with you. Bring your last two tax returns, or at least a rough sense of the income on them, and I can usually tell you within a few minutes whether IRMAA applies, whether you qualify for the adjustment form, and whether it’s worth timing anything on your end before it happens.

Questions people ask me about this
What income level increased my Medicare premium?
Medicare looks at your Modified Adjusted Gross Income from two years before the current year and applies a tiered surcharge, called IRMAA, once you cross a certain level. The exact thresholds change most years, so the safer approach is to check your specific tax return against the current tiers rather than rely on a number you saw elsewhere.
Does IRMAA apply to a Medicare Advantage plan or only a Supplement?
It applies to both, because it isn’t attached to the plan at all, it’s attached to your Part B premium, and sometimes your Part D premium. You’ll owe the same surcharge whether you enroll in a Medicare Advantage plan or add a Supplement on top of Original Medicare.
How far back does Medicare look at my income for this?
Two years. Your premium this year is generally based on the tax return from two years prior, which is why people who’ve just retired often see a surcharge tied to their last full working-year income even though their current income has already dropped.
Can I get the surcharge removed if my income has since dropped?
Sometimes, but only if the drop is tied to a recognized life-changing event, such as retirement, a spouse’s death, marriage, or divorce. If your income simply varies year to year without one of those specific triggers, there’s usually no form that adjusts it early. You wait for the two-year lookback to catch up.
Will a Roth conversion affect my Medicare premium?
It can. A Roth conversion counts as income in the year it happens, and if it pushes your Modified Adjusted Gross Income over a threshold, it can trigger a higher IRMAA tier two years later. This is usually controllable if you plan the size and timing of the conversion in advance.
Is the income threshold the same for a married couple as for a single person?
No. Couples filing jointly generally have more income room before the surcharge starts than a single filer does at the same income level. This matters most when a spouse passes away and the surviving spouse’s filing status changes even though income hasn’t.
Does the surcharge go away eventually if my income stays lower?
Yes, because it’s recalculated every year off a rolling two-year-old figure. A high-income year eventually rolls out of that window on its own, and your premium adjusts down to reflect it, without you having to do anything.

Find Medicare plans in your area
There are two different things here. First, if you want to see plan availability for your own ZIP code, use the plan lookup. That works by county, because Medicare Advantage and Part D availability changes at county lines. Second, the local county guides are an SEO/content library we are expanding to all 50 states, then down into county-level pages. Kentucky is the first live state layer, not the whole national structure.
