An Inherited IRA Emptied at 69, and a Medicare Bill Two Years Late

A 69-year-old woman who inherited her sister's IRA and withdrew the entire balance within one year received a Medicare premium bill two years later based on that one-time income, not on her actual current income.

A 69-year-old woman inherited her sister's IRA, signed the paperwork while she was still grieving, and drained the account inside a single year. Two years later, Medicare sent her a premium bill calculated as though that one-time withdrawal had been her salary. Her actual income by then looked nothing like it.

The case, described by 24/7 Wall St, is not a billing error. It is the intended result of two federal rules colliding: the way inherited retirement accounts are taxed on withdrawal, and the way Medicare sets premiums using a tax return that is two years old.

Why Medicare priced her off a year she no longer lives in

Medicare Part B and Part D premiums are not flat for everyone. Above certain income thresholds, beneficiaries pay an income-related monthly adjustment amount — IRMAA — on top of the standard premium. The surcharge is tiered: cross a threshold by a dollar and the whole tier applies.

The mechanism that surprises people is the lookback. Medicare does not ask what you earn now. It uses the modified adjusted gross income reported on the most recent tax return the Social Security Administration has on file, which in practice is the return from two years earlier. That is why a bill can arrive two years after the event that caused it, referencing a number the beneficiary has long since stopped thinking about.

For a retiree with a steady pension and Social Security, the two-year lag is harmless — income in one year looks much like income two years back. For someone who had a single enormous, non-recurring taxable event, the lag is punishing. The spike is captured; the return to normal is not, at least not until the tax returns catch up.

Emptying an inherited IRA is a taxable event, all at once

An inherited traditional IRA is not a windfall that arrives tax-free. Withdrawals from it are ordinary income to the person taking them, taxed at their marginal rate in the year of the distribution. Take the whole balance in one calendar year and the entire balance lands on one tax return.

That is the trap here. She did nothing improper — beneficiaries of an inherited IRA are generally required to empty the account within ten years of the original owner's death under current rules, so a full distribution is a permitted choice, not a violation. But choosing to do it in year one instead of spreading it over the available window concentrates every dollar of tax into a single year. And a single-year income spike is exactly what IRMAA is built to detect.

The mechanical consequences of compressing the distributions are worth stating plainly:

• Ordinary income tax on the full balance at the highest marginal rate the total reaches, rather than lower brackets spread across multiple years.
• An IRMAA surcharge on Part B and Part D premiums, applied two years later, for a full year.
• Potentially more of Social Security benefits becoming taxable in the spike year.
• No way to undo it — an inherited IRA distribution cannot be rolled back or returned to the account.

Spreading withdrawals across the permitted window does not eliminate tax. It flattens the peaks, and it is the peaks that trigger the surcharge tiers.

What an appeal can and cannot fix

Beneficiaries who believe their IRMAA determination is wrong, or who have had a genuine drop in income, can ask the Social Security Administration to reconsider using Form SSA-44, the life-changing event request. The form exists precisely because the two-year lookback can be wrong about a person's present circumstances.

The catch is that SSA-44 recognizes a defined list of life-changing events — things like the death of a spouse, marriage or divorce, work stoppage or reduction, loss of a pension, or loss of income-producing property. A large one-time IRA distribution is not itself on that list. Cashing out an inherited account is treated as a choice about timing, not as a change in circumstances imposed on the beneficiary.

That distinction is the whole difference between a surcharge that gets removed and one that has to be paid. Anyone in this position should still file — the determination is made case by case, and other qualifying events may have occurred in the same period — but should not assume the appeal is a formality.

The planning window is before the money moves, not after

The practical lesson runs backwards from the bill. Once the distribution is taken, the tax return is filed and the IRMAA determination follows almost automatically two years later. Everything that can be done is done in advance.

Illustratively, a beneficiary who inherits an account and takes an equal share of the balance in each of the ten years available has, in each of those years, one-tenth of the income the woman in this case reported in one — the same total taxable dollars, spread across ten returns instead of one. That kind of smoothing is what keeps a distribution from clearing an IRMAA threshold. It also gives room to time withdrawals around other income events: a property sale, a Roth conversion, the year Medicare enrollment begins.

Three questions are worth answering before signing inherited-IRA paperwork:

• What tax year will the money land in, and what else is already landing in that year?
• Which IRMAA tier does the combined figure reach, and what does the surcharge cost for the full year it applies?
• Is there a reason the money is needed now that outweighs the cost of concentrating it?

Grief is a bad time to make an irreversible tax decision, and the paperwork tends to arrive at exactly that moment. There is no penalty for leaving an inherited IRA in place while the answers are worked out — the requirement is that the account be emptied within the window, not immediately.

Where markets stood as this played out

The broader backdrop matters mainly for what an inherited account was worth at the moment of liquidation. As of the last trade on Tuesday, Aug. 25, 2026, the S&P 500 tracker SPY closed at $765.91, up 0.32% on the day from a prior close of $763.47. The Nasdaq 100 fund QQQ ended at $710.72, up 0.62%, and the Dow tracker DIA finished at $535.24, up 0.30%.

A rising market makes the timing question sharper, not softer. A larger balance means a larger single-year distribution if the account is emptied at once — and a larger figure on the tax return that Medicare will read two years later.

Frequently asked questions

What is IRMAA and why does it use old income?

IRMAA is the income-related monthly adjustment amount, a surcharge added to Medicare Part B and Part D premiums for higher-income beneficiaries. Social Security sets it using the modified adjusted gross income on the most recent tax return it has, which is generally the return from two years earlier. That lag is why a bill can reflect income you no longer have.

Is money from an inherited IRA taxable?

Withdrawals from an inherited traditional IRA are ordinary income to the beneficiary in the year they are taken, taxed at that person's marginal rate. The inheritance itself is not the taxable event; the distribution is. Taking the entire balance in one calendar year puts the whole amount on a single tax return.

How long do you have to empty an inherited IRA?

Under current rules, most non-spouse beneficiaries must fully distribute an inherited IRA within ten years of the original owner's death. Emptying it in year one is permitted but not required. Spreading withdrawals across the available years lowers the income reported in any single year, which is what determines tax brackets and IRMAA tiers.

Can you appeal a Medicare IRMAA surcharge?

Yes. Beneficiaries can file Form SSA-44 with the Social Security Administration to request a new determination based on a life-changing event, such as the death of a spouse, marriage or divorce, work stoppage, loss of a pension, or loss of income-producing property. Each request is reviewed individually.

Does a one-time IRA withdrawal count as a life-changing event?

A large one-time distribution from an inherited IRA is not one of the life-changing events SSA-44 lists. It is treated as a decision about timing rather than a change in circumstances. Beneficiaries can still file if another qualifying event occurred, but the withdrawal alone is unlikely to remove the surcharge.

How long does an IRMAA surcharge last?

An IRMAA determination applies for the premium year it covers, based on the tax return from two years earlier. If the income spike was a one-off, the surcharge normally falls away once the later, lower-income tax returns work their way into the calculation. In the meantime, the higher premiums are due.
