The Hidden Foe of Retirement: Proactive IRMAA Planning
For years, you focused on getting money into your retirement accounts. Now that you are nearing or in retirement, the most crucial question is: How do you take it out in the most efficient way possible?
This is where the difference between a simple advisor and a Personal CFO becomes clear. A transaction approach stops at simply distributing funds. A Personal CFO anticipates the ripple effects of every distribution—including a hidden, costly penalty known as IRMAA. Successfully navigating this is the core of smart IRMAA planning.
What Exactly Is IRMAA?
IRMAA stands for Income Related Monthly Adjustment Amount. It is an income-based surcharge that Medicare adds to your standard Part B and Part D premiums.
The critical thing to understand is the two-year look-back. The IRMAA surcharge is calculated based on your income reported to the IRS two years prior to the current Medicare year.
| Medicare Year | Income (MAGI) Used for Calculation |
| 2026 | 2024 Modified Adjusted Gross Income (MAGI) |
| 2025 | 2023 Modified Adjusted Gross Income (MAGI) |
This two-year gap is precisely why IRMAA can be such a dangerous, hidden foe in tax planning for retirees. A large, one-time income event you cause today won’t hit your Medicare premiums for 24 months, making the connection easy to miss.
The ‘Metanoia’ Shift: When Good Income Becomes Bad Income
Our philosophy of “Metanoia” requires you to look at your income not just as money for living, but as a lever that controls your future costs.
You have a large degree of control over your income in retirement, which typically comes from sources like:
-
Required Minimum Distributions (RMDs)
-
Withdrawals from your pre-tax IRA/401(k)
-
Capital Gains from selling investments
-
Taxable pensions
-
Social Security benefits
A common and costly scenario we see is the “Tax-Mistake” Roth Conversion.
Imagine you have a great year in retirement: you decide to execute a large Roth Conversion or sell a big investment to fund a major expense. You successfully move $50,000 into a higher tax bracket for that year, paying the income tax.
Two years later, that $50,000 bump in income pushes your MAGI over a key IRMAA threshold, resulting in significantly higher Medicare premiums for that entire year. That small, proactive tax decision may have unintentionally cost you thousands of dollars in hidden health insurance surcharges.
The mistake is that you were paying attention only to the income tax line but failed to anticipate the downstream IRMAA consequence.
2026 Medicare Part B IRMAA Tiers (Married Filing Jointly)
To understand the stakes, here are the official 2026 Part B premium thresholds for a married couple filing jointly, based on their 2024 Modified Adjusted Gross Income (MAGI). Notice the sharp jump in the total premium at each income “cliff.”
| Married Filing Jointly MAGI (Based on 2024) | IRMAA Surcharge (Monthly) | Total 2026 Monthly Part B Premium (Per Spouse) |
| Less than or equal to $218,000 | $0.00 | $202.90 |
| Greater than $218,000 and less than or equal to $274,000 | $81.20 | $284.10 |
| Greater than $274,000 and less than or equal to $342,000 | $202.90 | $405.80 |
| Greater than $342,000 and less than or equal to $410,000 | $324.60 | $527.50 |
| Greater than $410,000 and less than $750,000 | $446.30 | $649.20 |
| Greater than or equal to $750,000 | $487.00 | $689.90 |

How Your Personal CFO Integrates IRMAA Planning
As your Personal CFO, our job is to use your financial life plan to stress-test your tax decisions before you execute them. This is where a truly holistic approach pays off.
Our IRMAA planning strategy focuses on the following:
-
Modeling the “Cliffs”: We know exactly where the IRMAA income cliffs are, and we manage your MAGI to stay just below them. For example, if the first cliff for a married couple is $218,000, we model your annual income target at $217,000.
-
Targeted Roth Conversions: We use partial Roth Conversions to “fill up” a lower tax bracket but stop precisely before tripping an IRMAA cliff two years down the road.
-
Asset Location Strategy: We ensure you are drawing funds from the most advantageous sources. Tax-free distributions from a Roth IRA, for instance, do not count toward your MAGI and therefore do not impact your IRMAA. Conversely, selling appreciated assets in a taxable brokerage account does count.
-
Proactive Communication: Since the cost follows the income by two years, we constantly remind you of the long-term consequences of large, one-time income spikes before you make the trade.
Avoiding the IRMAA trap is one of the clearest ways that tax planning for retirees translates directly into real, tangible savings—often thousands of dollars per year. The savings go straight back into your retirement income stream.
Take the Next Step
As your Personal CFO, this is the kind of proactive, coordinated retirement income planning we perform every day. We don’t just see the tax form in front of us. We see the Medicare bill two years down the road.
