Medicare IRMAA Planning in Minnesota
Medicare IRMAA planning is the work of watching taxable income before and during retirement so a surcharge on your Medicare premiums does not arrive as a surprise two years later. 360 Financial, a fee-based fiduciary firm with offices in Wayzata and Elk River, Minnesota, handles this alongside tax and retirement income work rather than as a separate exercise, because it is the same income number driving all three.
The letter is what people remember. A retired engineer in Plymouth called us in November because Social Security had written to say his Medicare Part B premium was rising sharply, and he could not work out why. Nothing had changed in his life. What had changed, two years earlier, was that he sold a rental property. The surcharge was not a penalty. It was the system catching up with one large year of income, and a conversation before that sale would have changed its shape.
What IRMAA Is, and Why It Shows Up Late
IRMAA stands for income-related monthly adjustment amount, an extra charge added to Medicare Part B and Part D premiums for beneficiaries whose modified adjusted gross income sits above a set threshold. It is administered by the Social Security Administration, not Medicare itself, which is why the notice arrives on SSA letterhead. Two features make it worth planning around rather than reacting to.
The first is the lookback. Your premium for a given year is based on the tax return filed two years earlier, so the income that sets your 2027 premium is what you reported for 2025. By the time the surcharge appears, the year that caused it is closed.
The second is the shape of the brackets. IRMAA is not a gradual phase-in. It steps. Crossing a threshold by a single dollar moves you into the next tier for the full year, for both Part B and Part D, and for each spouse separately on a joint return. That is the detail that makes Medicare IRMAA planning worth real attention in the handful of years where income is unusually high.
Income event in the lookback year | Typical effect | Where planning can help |
Large Roth conversion | Raises modified adjusted gross income for that year | Sizing the conversion to stop below the next threshold |
Sale of a business or property | One-time capital gain, often a multi-tier jump | Spreading the gain or timing it before age 63 |
Required minimum distributions begin | Permanently higher baseline income | Earlier partial withdrawals to flatten the curve |
Death of a spouse | Same income, single filing thresholds | Reviewing withdrawals in the first full single year |
Retirement or reduced hours | Income falls, premium lags two years behind | Form SSA-44 for a qualifying life-changing event |
The Minnesota Pieces People Miss
Minnesota taxes Social Security benefits and capital gains at ordinary income rates, so a year that creates an IRMAA surcharge frequently creates a larger state tax bill in the same breath. The two are worth looking at together rather than in separate meetings.
Cabin and lake property sales are the other recurring one. Families across the Twin Cities, from Wayzata out through Elk River, Rogers and St. Michael, hold property bought decades ago at a fraction of today's value. Selling it in one tax year can produce a gain large enough to push a retired couple several IRMAA tiers higher. An installment sale, a charitable strategy or simply moving the closing across a calendar line can change that outcome, which is the argument for talking before the listing agreement rather than after the closing.
The pre-Medicare years matter just as much. Between an early retirement and age 65, healthcare often runs 15,000 to 25,000 dollars a year for a couple buying their own coverage, and marketplace subsidies are income-tested too. Medicare IRMAA planning simply extends that same discipline across the age 65 line.
Medicare IRMAA Planning Starts at Age 63
Because of the two-year lookback, the first year that can affect your Medicare premium is the year you turn 63. Clients are often surprised by that, since nothing about Medicare has happened yet.
Medicare IRMAA planning therefore opens earlier than most people expect. Years before 63 are generally the cleanest time for larger Roth conversions, for realizing concentrated gains, or for taking a lumpy distribution, since those years sit outside the lookback entirely. From 63 onward, the same move needs a second column in the analysis.
This is where our LifeWealth Process tends to earn its place, since it looks at Family, Occupation, Recreation and Money together rather than one account at a time. A planned sabbatical, a business sale or a decision to help a child with a down payment all land in the same income calculation, and they are easier to sequence when they are on one page.
When a Surcharge Is Worth Appealing
Not every IRMAA notice has to stand, and this is the one part of Medicare IRMAA planning that happens after the fact. Social Security recognizes a defined list of life-changing events, filed on Form SSA-44, that let you ask for the premium to be set on current income instead of the two-year-old return. Retirement or reduced work hours, marriage, divorce, the death of a spouse, loss of a pension and loss of income-producing property are the common ones.
A one-time capital gain is not on that list, which is the usual disappointment. Selling a cabin or exercising options is treated as income, not a life-changing event. That is why planning ahead of the event matters more than the paperwork after it.
If you are newly retired and the surcharge reflects your working income, file the form. Our wealth management team works through it with clients regularly, usually with the retirement date confirmation attached.
Working With a Team Rather Than a Single Advisor
Medicare IRMAA planning sits in the seam between tax work and retirement income work, which is where things fall through when the two sides never speak. 360 Financial is organized as a team, with CFP professionals and CPAs looking at the same household, so a conversion recommendation and a tax projection are not produced in different buildings. Advisors including Michael Urch, Will Grant, Mitch Zweber and Mike Rogers work with Minnesota families on this sequencing from the Wayzata and Elk River offices.
Frequently Asked Questions
Who should be thinking about Medicare IRMAA planning? Anyone approaching 63 with large retirement balances, and anyone with a one-time income event in view, such as a business sale, a property sale or a Roth conversion.
How far back does Medicare look at my income? Two years. The return you file for a given year generally sets your Medicare premiums two years later.
Does one dollar over an IRMAA threshold really matter? Yes. The brackets step rather than phase in, so crossing a threshold moves you to the next tier for the whole year and for both Part B and Part D.
Do the thresholds change each year? They are adjusted annually, so confirm the figures for a given year against current Social Security guidance.
Can a Roth conversion still make sense if it triggers IRMAA? Often it can. A surcharge lasts one year, while the tax position a conversion creates lasts much longer. Medicare IRMAA planning is about seeing both numbers rather than one.
What if my income has already dropped since that tax year? File Form SSA-44 if your situation matches a listed life-changing event. Social Security can then use current income instead.

Traditional IRA account owners have considerations to make before performing a Roth IRA conversion. These primarily include income tax consequences on the converted amount in the year of conversion, withdrawal limitations from a Roth IRA, and income limitations for future contributions to a Roth IRA. In addition, if you are required to take a required minimum distribution (RMD) in the year you convert, you must do so before converting to a Roth IRA.
A Roth IRA offers tax deferral on any earnings in the account. Qualified withdrawals of earnings from the account are tax-free. Withdrawals of earnings prior to age 59 1/2 or prior to the account being opened for 5 years, whichever is later, may result in a 10% IRS penalty tax. Limitations and restrictions may apply.
