How to Avoid the IRMAA Cliff: Strategies for High-Income Clients

Here's a scenario I see constantly: a client retires with a $1.2 million IRA and a pension, sails through their first year of Medicare at the standard premium, then gets blindsided in year two when Social Security withholds an extra $296.90 per month. Nobody warned them. The Roth conversions they did the year before pushed them over the $133,000 threshold, and now they're paying $481.90 a month for Part B — and that's before Part D surcharges hit.

That's the IRMAA cliff. And it's avoidable — if you plan around it before the income hits.

What the Cliff Actually Looks Like

IRMAA (Income-Related Monthly Adjustment Amount) adds surcharges to Medicare Part B and Part D premiums when a client's Modified Adjusted Gross Income crosses specific thresholds. In 2025, those thresholds for individual filers look like this:

• ≤$106,000: Standard Part B premium of $185.00/month — no surcharge
• $106,001–$133,000: $259.00/month — an extra $888/year per person
• $133,001–$167,000: $370.60/month — an extra $2,227/year per person
• $167,001–$200,000: $481.90/month — an extra $3,563/year per person
• $200,001–$500,000: $593.20/month — an extra $4,898/year per person
• Above $500,000: $629.40/month — an extra $5,332/year per person

Married filing jointly thresholds are roughly double. But the structure is the same: one dollar over the line and you're in the next bracket for the entire year.

Part D adds more. The 2025 IRMAA Part D surcharges range from $13.70 to $85.80 per month on top of the plan premium. For a married couple both on Medicare, crossing from the first bracket to the second means over $2,000 in extra costs annually. Crossing from the first to the third is a $7,000 swing.

That's the cliff. It's not a metaphor — it's a step function.

The Two-Year Lookback Is the Variable Most Advisors Miss

Social Security uses income from two years ago to set IRMAA. In 2025, they're looking at 2023 MAGI. This creates a planning window — and a trap.

The window: if a client is retiring in 2025 and their income is dropping, you can often make the case that 2025 IRMAA should be recalculated using current income. More on that below.

The trap: a large Roth conversion in 2023 shows up in 2025 IRMAA. An unusually large RMD the same year compounds it. A client who sold a business or rental property in 2023 might be paying IRMAA surcharges in 2025 on income they no longer have.

Map the two-year lookback for every client approaching Medicare eligibility. Build a rolling income calendar that shows projected MAGI two years out. Most advisors don't do this until the damage is done.

Strategies That Actually Reduce MAGI

Not every income-reduction strategy moves the IRMAA needle. These do.

Qualified Charitable Distributions

For clients over 70½ with IRA assets and charitable intent, QCDs are the cleanest tool available. Up to $108,000 in 2025 can be distributed directly from an IRA to a qualified charity, satisfying RMD requirements without touching MAGI. A client taking a $60,000 RMD and making $30,000 in QCDs reduces their MAGI by exactly $30,000. That might be enough to stay under the $106,000 threshold.

Strategic Roth Conversion Planning

Roth conversions reduce future RMDs and future IRMAA exposure — but they add to MAGI in the conversion year. The job is to convert up to the next IRMAA bracket, not over it. If a client's income sits at $85,000, you have $21,000 of room before the $106,000 cliff. Use it. Don't accidentally convert $40,000 and push them into the second bracket.

Model the conversion amount against the IRMAA brackets explicitly. This isn't just about income tax brackets — it's a dual optimization.

Harvesting Capital Losses

Realized capital gains count toward MAGI. Capital losses offset them. If a client has embedded losses in taxable accounts, there's often an opportunity to harvest them in the same year as a large capital gain event — a business sale, a property disposition, or a large RMD year.

Timing of Discretionary Income

This one requires a two-year mindset. If a client needs a large distribution — a home purchase, a gift to children, a one-time expenditure — consider whether it could shift to a year when MAGI is already elevated (and the damage is done) versus a year when they're clean. Stacking income into high-income years and keeping low-income years clean is basic bracket management, but it applies to IRMAA too.

Health Savings Account Contributions

For clients still working and covered by an HDHP before Medicare, HSA contributions reduce MAGI dollar-for-dollar. The 2025 family limit with the 55+ catch-up is $8,300. Not large, but meaningful if you're close to a threshold.

When the Cliff Has Already Been Hit: IRMAA Appeals

Sometimes the income event already happened. A client sold a business in 2023, took a large distribution, or had a one-time spike. They're now paying 2025 IRMAA surcharges on income they no longer have.

SSA Form SSA-44 allows clients to request a reduction in IRMAA based on a "life-changing event." The qualifying events are specific: marriage, divorce, death of a spouse, work reduction, work stoppage, loss of pension, or employer settlement payment. A standard income drop doesn't automatically qualify unless it's tied to one of these events.

Retirement does qualify as a work stoppage. If a client's income dropped because they retired in 2024 or 2025, they can file SSA-44 and provide evidence of the income change. Social Security will then calculate IRMAA based on their estimated current-year income instead of the two-year-old figure.

This isn't guaranteed, and it requires documentation. But for clients who retired and now have MAGI well below the first threshold, it's worth the filing. A successful appeal can recover $888 to over $5,000 per person per year.

Key Takeaways

• One dollar over an IRMAA threshold costs a couple over $2,000 annually — precision income management in the years before Medicare starts is not optional.
• The two-year lookback means IRMAA planning is really income planning two years in advance; build that into your financial planning calendar.
• QCDs are the cleanest MAGI reducer available to clients over 70½ — if they're charitable at all, this should be the first tool you reach for.
• Roth conversions should be sized against IRMAA brackets, not just income tax brackets; most conversion planning software doesn't model this automatically.
• SSA-44 appeals are underused — if a client retired and their income dropped, filing takes an hour and can recover thousands per year.
• For married couples, each spouse's Medicare is assessed separately — you can sometimes structure income so one spouse avoids a bracket the other hits.
