⚠ The cliff effect is real. IRMAA is NOT a progressive tax — crossing a threshold by $1 triggers the entire surcharge for that bracket. For a married couple both on Medicare, a $1 overage can cost $2,000+ per year in combined surcharges.
📋 Form SSA-44 — Appeal if your situation has changed
If you've had a qualifying life-changing event (retirement, divorce, death of a spouse, loss of income-producing property, reduced work hours), you can appeal your IRMAA determination. File Form SSA-44 with your local Social Security office within 60 days of the IRMAA notice.

When a spouse dies, the surviving spouse files as Single — where IRMAA thresholds are roughly half of Married Filing Jointly. A couple comfortably in Tier 1 as MFJ with $250,000 income would suddenly land in Tier 3 or 4 as a single filer with the same income. Planning should model the surviving spouse scenario proactively.
📄 Qualified Charitable Distributions (QCDs)
If you're 70½ or older, QCDs allow direct IRA distributions to charity up to $105,000/year (2026). QCDs satisfy RMD requirements but are NOT included in MAGI — unlike regular IRA distributions. One of the most effective tools for charitably inclined clients facing RMD-driven IRMAA exposure.
🔄 Stage Roth conversions carefully
Roth conversions count as MAGI in the year converted and flow through to IRMAA two years later. Calculate your remaining "room" to the next bracket and convert only up to that boundary. Conversions that stay within the current bracket are IRMAA-neutral.
🏘 Manage capital gains timing
Investment sales, property sales, and portfolio rebalancing all flow into MAGI. Consider spreading gains across tax years or using tax-loss harvesting near bracket thresholds. The income decision made today affects 2028 Medicare premiums — not 2026.
📊 Blend withdrawal sources
With a mix of traditional IRA, Roth IRA, and taxable accounts, strategically blending withdrawal sources can keep MAGI below the next threshold without reducing total spendable income. Roth withdrawals and HSA distributions for qualified medical expenses don't add to MAGI.
💵 Muni bond interest counts toward MAGI
Tax-exempt interest from municipal bonds is excluded from AGI but IS added back to compute Medicare MAGI. Clients who hold significant muni bond positions should understand that the tax exemption doesn't shield them from IRMAA — this often surprises people who assumed muni bond income was "invisible" to Medicare.
