She Took the Pension as a Lump Sum and Had the Check Cut in Her Name. The 20% Withheld Was the Small Problem. Medicare’s Bill Was the Big One
She deposited the pension check, filed her taxes, and considered the matter settled. Two years later, a bill arrived that had nothing to do with the IRS and everything to do with a single line on the payee field.

A single retiree, 66, left her employer years earlier with a deferred pension waiting in the wings. In 2024 she elected the $150,000 lump sum and asked the plan to cut the check in her name. The envelope arrived with $30,000 already withheld for federal tax. She deposited the remaining $120,000, filed her return the following April, and assumed the matter was closed.
Two years later, her Medicare bill told a different story. The Social Security Administration used her 2024 tax return to reset her 2026 premiums, and the pension check she thought she had settled with the IRS added $6,355.20 to her Medicare costs for the year.
If you took a taxable pension payout in 2024 or 2025 and did not initiate a rollover, your two-year premium clock may have begun ticking. If your pension sits with a plan administrator and no distribution is scheduled, you have time to avoid the version of this scenario that hurts.
Troubleshooting the Fallout
An eligible pension distribution paid to the participant carries mandatory 20% federal withholding under the tax code. That withholding is only a down payment on tax. Assuming the pension is entirely pretax, the full distribution enters taxable income unless it is rolled over, and the amount she actually received is irrelevant to how the IRS scores it.
A direct rollover to an IRA would have produced neither taxable income nor mandatory withholding. A check payable to an “IRA Custodian FBO” designation can still qualify as a direct rollover even if it is mailed to her home. A check payable to her personally instead triggers the 20% withholding and initiates the 60-day window for completing the rollover herself.
60-Day Cure She Did Not Use
Because the check was payable to her, the IRS gave her 60 days to complete an indirect rollover. To shelter the full $150,000, she needed to deposit the $120,000 she received into an IRA and replace the withheld $30,000 out of her own pocket. The withheld amount would then come back as a refund or credit on her return.
If she rolled over only the $120,000 she received, the missing $30,000 stayed in income. Limited hardship waivers of the 60-day rule exist, but they are narrow exceptions rather than a reliable strategy.
How the Check Reached Medicare
Take the clean single-filer math. Ordinary MAGI of $60,000 plus a taxable pension distribution of $150,000 puts her 2024 modified adjusted gross income (MAGI) at $210,000. MAGI for IRMAA is adjusted gross income (Form 1040, line 11) plus tax-exempt interest (line 2a), so municipal bond income counts here too.
Under the 2026 CMS tables, a single filer between $205,000 and $500,000 pays a Part B surcharge of $446.30 per month on top of the $202.90 standard premium, and a Part D surcharge of $83.30 per month. Combined, the IRMAA add-on runs $6,355.20 for the year. The mid-3% Social Security COLA tracking for 2027 will not come close to absorbing that.
Medicare simply read the tax return she filed and priced her premiums accordingly. And SSA-44, the life-changing-event appeal, does not apply here. A voluntary pension election is not on the qualifying list, which covers events like work stoppage, death of a spouse, or divorce. She had already retired, so there is no work-stoppage angle to argue (IRMAA is one of several premium traps we mapped in a free Medicare guide).
Before the Pension Check Is Cut
Take the following steps before cashing in:
- Ask the plan for its direct-rollover instructions in writing and confirm who will appear on the payee line. “Mailed to me” is fine. “Payable to me” is the trap.
- If a participant-payable check has already arrived, mark the 60-day deadline on the calendar today and confirm you have outside cash to replace the withheld 20% before you spend a dime.
- If your MAGI is within $20,000 of an IRMAA bracket in a distribution year, a fee-only advisor who models Medicare premiums alongside tax can price the true cost of taking the money now versus rolling it over and drawing later.
The pension offered her the same $150,000 either way. One line on the check decided whether it landed in an IRA or on the income record Missing it put the pension on the income record Medicare saw two years later.
