Does a Roth Conversion Affect IRMAA? What to Know Before Converting?
If you're considering converting your traditional IRA to a Roth IRA, it's important to understand how this decision might impact your Medicare premiums through the Income-Related Monthly Adjustment Amount (IRMAA). This article aims to clarify what IRMAA is and how a Roth conversion could affect your Medicare costs.

What Is IRMAA Before a Roth Conversion?
IRMAA stands for Income-Related Monthly Adjustment Amount. It's an extra charge on top of your standard Part B premiums if you have higher income. The amount you pay in IRMAA depends on the Modified Adjusted Gross Income (MAGI) reported in your tax return from two years prior.
IRMAA generally uses the most recent federal tax return the IRS provides, often from two years earlier. For 2026, IRMAA begins above $109,000 for an individual return and above $218,000 for a joint return.
How Does a Roth Conversion Affect IRMAA?
When you convert money from a traditional IRA to a Roth IRA, the amount converted is considered taxable income in the year of conversion. This can temporarily increase your MAGI for that tax year. If this bump pushes your income above the thresholds set by Medicare, it could trigger or raise your IRMAA payments.
For instance, if a taxable Roth conversion pushes MAGI above an IRMAA threshold, it can increase Medicare premiums for the year tied to that tax return, generally two years later. A Roth conversion itself is not an IRMAA life-changing event for a new determination.
Which IRMAA Factors Matter Before a Roth Conversion?
Before you decide to convert your IRA to a Roth IRA, it's important to consider the potential impact on your future Medicare premiums. Here are some steps you can take:
1. Calculate Your MAGI: Understand how much of your income comes from different sources, such as wages, investments, and pensions. This will help you estimate whether a large conversion could push you over an IRMAA threshold.
2. Consult a Financial Advisor or Tax Professional: These experts can provide personalized advice based on your specific financial situation. They can help you understand the tax implications of converting and how it might affect your Medicare premiums in future years.
3. Plan Your Conversion Strategy: If you decide to go ahead with a conversion, consider spreading it out over multiple years instead of doing a large single conversion. This strategy could keep your income below the IRMAA thresholds each year.
4. Review Annual Updates on IRMAA Thresholds: The IRS and Medicare update these thresholds annually based on inflation rates. Stay informed about any changes that might affect you in future tax years.
What Are the Longer-Term IRMAA Implications of a Roth Conversion?
While a Roth conversion can offer significant long-term benefits, such as tax-free withdrawals in retirement, it's important to weigh these against the potential short- and medium-term impact on your Medicare premiums.
If you are close to an IRMAA threshold, a large conversion could have a noticeable effect on your costs. However, if you're far below the thresholds or expect your income to naturally decrease over time (for example, after retirement), a Roth conversion might be less risky in terms of Medicare expenses.
Additionally, consider that any extra premiums due to IRMAA will only affect future years based on past income reports. This means that while the initial increase in MAGI from a Roth conversion can cause higher premiums later, it won't impact your current Medicare costs.
How Do Roth Conversion Income and IRMAA Interact?
A Roth IRA conversion is a significant financial decision with potential implications for your Medicare premiums through IRMAA. By understanding how this process works and planning carefully, you can make informed choices that align with both your retirement goals and healthcare needs.
