Retired Police Officer With $890,000 Discovers His Pension Just Triggered an IRMAA Surprise

Frank retired from a mid-sized city police department at 55 on his pension. At 66, he filed for Social Security and began drawing from his 457(b), confident his retirement math was settled. Then the Social Security Administration sent an IRMAA determination letter. His Medicare premiums were rising because his income had crossed a bracket he had never heard of.

This is a common scenario for retired public-safety workers. The pension is generous, the 457(b) grew for decades, Social Security kicked in, and the combined income quietly pushed Modified Adjusted Gross Income (MAGI) past the first Medicare surcharge threshold. Nobody warned him. The letter arrived, and the damage was already done for that premium year.

How the Numbers Stack Up

Frank has $890,000 saved: $610,000 in a 457(b), $280,000 in a taxable brokerage account, plus the pension. Add Social Security and even a modest 457(b) withdrawal, and MAGI can easily clear six figures.

The line that matters is $109,000 in MAGI for a single filer. Cross it by even a dollar and surcharges begin with no grace period. In the first IRMAA tier (MAGI above $109,000 up to $137,000), Frank pays an extra $81.20 per month on Part B, bringing his total Part B premium to $284.10 versus the standard $202.90. Part D adds another $14.50 per month in surcharges. Together, those two line items add up to roughly $1,148 per year in extra Medicare costs, which is exactly the kind of number that lands in a letter and stuns someone who thought the retirement math was done.

IRMAA operates on a two-year lookback. The MAGI on the tax return filed this year determines the premium two years from now. Frank’s 2026 surcharge was set by his 2024 return. Whatever he withdraws in 2026 will shape his premium in 2028, which means the clock for action is always running two years ahead.

The Real Tension: Fixed Pension, Flexible Withdrawals

Frank cannot change the pension. He cannot un-file for Social Security without complications. The only real lever is the 457(b), and retired officers actually have an advantage most retirees do not.

A 457(b) is penalty-free at any age after separation from service, which is why many cops draw it down aggressively in their 50s. That works well until the pension, Social Security, and any remaining 457(b) distributions stack up in the same tax year and push MAGI over a cliff. One dollar of extra income above $109,000 can cost more than $1,100 in annual premiums, with no phase-in and no grace period.

The single most useful move for a retired officer in Frank’s position is the Healthcare Enhancement for Local Public Safety (HELPS) provision, found at Internal Revenue Code Section 402(l). It lets eligible retired public-safety officers exclude up to $3,000 per year of pension income used for health or long-term-care insurance premiums. If both spouses qualify, the combined exclusion reaches $6,000 annually. That reduction in taxable income flows directly into lower MAGI, which can pull Frank back under $109,000 in a borderline year. Under the original HELPS rules, premiums had to be paid directly by the pension plan to the insurer. SECURE 2.0 Section 328, enacted in December 2022, relaxed that requirement so premiums paid directly by the retiree now also qualify. The retiree simply pays the insurer and provides a written attestation when filing, though Frank should still confirm the mechanics with his pension administrator before claiming the exclusion on his return.

Two Paths Worth Considering

The most direct strategy combines HELPS with bunching. Instead of taking level 457(b) withdrawals every year, Frank alternates: a lean year where MAGI stays under $109,000, then a heavier year where he pulls extra to fund the next year’s spending. He accepts the surcharge in the heavy year and avoids it in the light year. Over a decade, this approach can save five figures in cumulative premiums.

The second path involves Qualified Charitable Distributions, which become available at age 70½. That is well before Required Minimum Distributions begin at age 73. Starting at 70½, Qualified Charitable Distributions let Frank send up to $111,000 per year (the 2026 limit, indexed annually for inflation per IRS Notice 2025-67) from an IRA directly to charity without adding a dollar to MAGI. Once RMDs arrive at 73, those same QCDs satisfy the distribution requirement and keep the income off the return entirely. If Frank rolls the 457(b) into a traditional IRA before RMD age, QCDs become a permanent IRMAA-management tool for anyone who was already planning to donate. Under 2026 tax rules enacted through the One Big Beautiful Bill Act, QCDs carry added value because they sidestep the new 0.5% AGI floor that now applies to itemized charitable deductions for all filers who itemize, not just high earners.

What to Do This Week

1. Pull the IRMAA letter and confirm the tier. If Frank is in the first bracket by a small margin, HELPS may fully solve the problem. If he is deeper into a higher tier, the strategy shifts to multi-year bunching.
2. Model 2026 MAGI now, not at tax time. The withdrawal Frank takes in December 2026 sets his 2028 premium. Waiting until April 2027 to look at the return leaves no room to change anything.
3. File Form SSA-44 if a life-changing event applies. Retirement itself qualifies, as do divorce, a spouse’s death, and loss of pension income. Many retirees pay a surcharge for a year they did not have to simply because they never filed the appeal.

Editor’s note: This pass updated the 2026 Tier 1 Part B surcharge from $81 to the precise $81.20, the standard Part B premium from $203 to $202.90, the total Tier 1 Part B premium from $284 to $284.10, and the annual extra Medicare cost at Tier 1 from a broad range to the specific $1,148 figure. It also corrected the scope of the 0.5% AGI floor on itemized charitable deductions: that rule applies to all itemizers under the One Big Beautiful Bill Act, not only to high earners. The QCD section was restructured to clarify that QCDs are available at age 70½, which is earlier than the RMD start age of 73.
