Most homeowners over 50 spend considerable time thinking about what a home sale will mean for their next chapter. Where will they go? What will the process look like? However, one question that rarely makes the list is this: could selling my home increase my Medicare premiums? For anyone researching IRMAA Medicare Chicago area homeowners need to understand, the answer is yes. It absolutely can. Consequently, knowing what IRMAA is, how it works, and how to plan around it could save you thousands of dollars in the years following your sale.
This blog explains the concept clearly and without jargon. Read it before you talk to your financial advisor.
What Does IRMAA Stand For?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is a surcharge added to your standard Medicare Part B and Part D premiums when your income exceeds certain thresholds. In other words, if you earn above a certain amount in a given year, Medicare charges you more the following year.
The Centers for Medicare and Medicaid Services sets these thresholds annually and adjusts them over time. Notably, IRMAA does not affect most people in most years. However, a significant one-time income event can push you into an IRMAA bracket. Selling a home is exactly that kind of event.
How Does a Home Sale Create an IRMAA Problem?
When you sell your home, any taxable capital gain counts as income in the year of the sale. Most homeowners over 50 qualify for the Section 121 exclusion. This allows a single filer to exclude up to $250,000 in profit. A married couple can exclude up to $500,000. The IRS provides full details on this exclusion and the qualifying requirements.
However, if your gain exceeds those thresholds, the excess becomes taxable income. Additionally, some homeowners do not qualify for the full exclusion. This is particularly true for those who have not lived in the home for two of the last five years. Even gains within the exclusion can sometimes interact with other income sources in ways that push your total reported income higher than expected.
Here is the part that catches people off guard. Medicare does not look at your current year’s income when setting your premiums. It looks at your income from two years prior. This is called the two-year lookback. Therefore, if you sell your home in 2025 and report a significant taxable gain, Medicare may use that figure to set your premiums in 2027. By the time the higher bill arrives, many homeowners have completely forgotten the connection.
The IRMAA Cliff Effect
This is where IRMAA becomes particularly important to understand. The surcharge does not phase in gradually. It operates in brackets. Cross a threshold by even one dollar, and you jump into the next bracket entirely. That can mean a significant increase in your monthly premium.
For 2026, Medicare.gov publishes the standard Part B premium alongside the IRMAA brackets. The jump from one bracket to the next can add hundreds of dollars per month per person. For a married couple, both of whom may trigger IRMAA simultaneously, the annual impact can be substantial.
This bracket structure is precisely why the cliff effect matters. A small difference in how a sale is structured can determine which bracket you land in. Furthermore, even a short delay in closing, pushing a sale from December into January, can shift the income into a different tax year. Consequently, that timing decision alone can change the IRMAA outcome significantly.
What Can You Actually Do About It?
The good news is that IRMAA is not inevitable. Even when it applies, there are strategies to manage it. However, these strategies require planning before the sale, not after.
First, work with a CPA who understands real estate transactions and their interaction with Medicare. Many general accountants are not deeply familiar with IRMAA. Ask specifically about it. The National Association of Tax Professionals can help you find a qualified advisor in the Illinois area.
Second, consider the timing of your sale carefully. If you have flexibility on when you close, your financial advisor can model the income impact across different scenarios. This identifies the least costly approach before you commit to anything.
Third, know that IRMAA determinations are not permanent. If your income drops back down in subsequent years, your Medicare premiums will follow. Additionally, Medicare offers a formal appeals process called a Life-Changing Event appeal. If your income has dropped significantly since the year Medicare is basing your premium on, you may qualify to have your premium recalculated. Medicare.gov outlines this process in full detail.
