The standard Medicare Part B premium is $202.90 a month in 2026, or roughly $2,435 a year before you add a Part D drug plan, a Medigap policy, or the $283 annual Part B deductible. That is the floor for a typical retiree. Higher-income beneficiaries can pay far more, and the difference often comes down to one number: Medicare MAGI.

That number is MAGI, and the rule it triggers is called IRMAA. CMS says about 8% of people with Medicare Part B pay an IRMAA surcharge. If your household modified adjusted gross income sits comfortably below $109,000 single or $218,000 joint, IRMAA may not be an immediate concern. If you are within $25,000 of either line, or you are planning a Roth conversion, a home sale, or a large IRA withdrawal in the next two years, the rest of this article is for you.

How a single income event reshapes two years of premiums

IRMAA stands for Income-Related Monthly Adjustment Amount. Social Security uses your tax return from two years prior to set this year’s surcharge. Your 2024 tax return drives your 2026 premium; your 2026 return will drive your 2028 premium. MAGI for IRMAA means adjusted gross income (Form 1040, line 11) plus tax-exempt interest (line 2a). Municipal bond income that feels tax-free still counts here, which is the surprise that quietly pushes near-the-line retirees into the first tier.

The 2026 brackets and surcharges look like this for joint filers:

A couple that crosses the first line by even one dollar pays about $2,297 in extra premiums for the year, on top of two standard Part B premiums. A couple at the top tier pays close to $13,872 in surcharges alone. That is the cost of misreading the cliff.

The survivor trap nobody plans for

One of the most expensive IRMAA events can be the death of a spouse. In the year of death, a surviving spouse may still be able to file a joint return, and some survivors with dependent children may qualify for favorable filing status for two more years. But many older survivors eventually file as single, where the first 2026 IRMAA threshold is $109,000 instead of $218,000. Income often falls after a spouse dies, but it may not fall by half.

This matters because Medicare costs do not rise only through annual premium inflation. For a surviving spouse, the bigger problem can be the filing-status change that cuts the IRMAA threshold roughly in half. That shift can raise Medicare premiums even when the survivor’s lifestyle and spending needs have not changed much.

What SSA-44 actually does, and what it does not

Form SSA-44 lets you ask Social Security to lower IRMAA when a qualifying life-changing event reduces household income. The qualifying list is narrow: marriage, divorce or annulment, death of a spouse, work stoppage, work reduction, loss of income-producing property, loss of pension income, or receipt of certain employer settlement payments. A Roth conversion, home sale, or large RMD generally does not qualify if the issue is simply that you voluntarily raised taxable income.

What the smart 5% actually do

A practical IRMAA plan usually comes down to three habits: time large income events before the lookback years, watch the income lines that are easy to overlook, and appeal quickly when a real qualifying event lowers income.

• Sequence income before the Medicare lookback years. The 2024 return generally drives 2026 premiums, so a Roth conversion, deferred-comp payout, or stock sale done at 63 can affect premiums at 65. Front-loading conversions in your late 50s and early 60s can help, but the right cutoff depends on when you enroll in Medicare and whether the tax savings justify the temporary income spike.
• Watch the tax-exempt interest line. Muni bond income on line 2a of Form 1040 counts toward MAGI for IRMAA, even though it may be exempt from federal income tax. A retiree sitting $4,000 under the first joint threshold can be pushed over by tax-exempt interest they thought was invisible.
• File SSA-44 promptly when a qualifying event lowers income. If you retire, lose a spouse, or stop work mid-year, submit the form with documentation rather than assuming Social Security will immediately reflect your lower income. Avoid promising yourself a refund, though; the result depends on the event, your estimated income, and Social Security’s review.

Model the Cliff Before You Create It

If your household income sits within $20,000 of any IRMAA line and you are weighing a Roth conversion, model the tax cost and the Medicare surcharge together. The 2.8% Social Security COLA for 2026 will not cover a bracket jump you triggered yourself, especially if both spouses pay Part B and Part D surcharges for a full year.

The Premium Is Manageable. The Surprise Is Not.

IRMAA is not a reason to avoid every Roth conversion, capital gain, or IRA withdrawal. It is a reason to price those moves correctly before the tax year closes. Once the two-year lookback reaches your return, a few extra dollars of MAGI can turn into a full year of higher Medicare premiums.
