“Income-Related Monthly Adjustment Amount” (IRMAA) is an additional fee charged to higher-income Medicare beneficiaries in addition to their Medicare Part B and Part D premiums.
However, being categorized as “high income” does not necessarily mean only “super wealthy” individuals are affected by this additional fee. In fact, there are various reasons that can place you within the scope of IRMAA.
Medicare Part B covers medical services outside of hospital inpatient care, while Part D covers prescription drug costs.
If you find your Medicare premiums suddenly increased, understanding the reason for the adjustment is crucial. Equally important is to know your rights to appeal and protect your interests if you believe the adjustment is erroneous.
According to the Centers for Medicare & Medicaid Services (CMS) in the United States, starting from 2007, Medicare beneficiaries’ monthly Part B premiums are calculated based on income.
For individuals filing taxes individually, if their Modified Adjusted Gross Income (MAGI) is below or equal to $109,000, they are exempt from paying this additional fee. In 2026, such beneficiaries pay the standard premium of $202.90 per month.
Similarly, for beneficiaries filing taxes jointly, if their MAGI is $218,000 or below, they do not need to pay the IRMAA surcharge, only the standard premium.
However, surpassing these income thresholds results in being levied the IRMAA fee. IRMAA follows a tiered system, where higher income corresponds to higher additional fees in the respective tier.
The monthly premiums for Part D also follow a similar calculation method.
The Social Security Administration (SSA) determines the IRMAA amount based on your tax information from two years prior.
According to Medicare Resources, the 2026 Medicare premiums are calculated based on tax information from 2024. These amounts are recalculated annually, but the income data used typically lags by two years.
IRMAA may increase your Medicare premiums by hundreds of dollars, but life circumstances can change suddenly. Therefore, if your income is affected due to certain circumstances, you can appeal the IRMAA decision.
If you’ve experienced a significant life event causing a decrease in income, you can request SSA to reevaluate their initial determination.
The following are considered significant life events:
– Death of a spouse
– Marriage
– Divorce or annulment
– You or your spouse stop working or reduce work hours
– Involuntary loss of income-producing property due to natural disasters, illness, fraud, or other circumstances
– Loss of a retirement pension
– Closure or bankruptcy of a current or former employer resulting in receiving a settlement
You can also provide reasons to SSA indicating the use of outdated or incorrect information in calculating your IRMAA.
For example, if you submit an amended tax return to the Internal Revenue Service (IRS) or possess newer tax information showing your income lower than SSA’s original determination.
Failure to report significant life events to SSA could lead to overpayment of thousands of dollars in Medicare premiums.
If you need to request a recalculation of IRMAA due to a significant life event, you must fill out Form SSA-44. You can submit this form to SSA to apply for a reduction in IRMAA. If you need assistance in completing the form, you can call 1-800-772-1213 and inform the representative of your significant life event, expressing the desire to reduce your Medicare IRMAA.
If you don’t meet the qualifications to request a review of the initial determination but still disagree with the IRMAA decision, you can still appeal.
However, SSA does not strictly stipulate a time frame for responding to or processing your application. If your application is successful, your Medicare premium amount will be adjusted.
If your application is denied, you can appeal further to the Office of Medicare Hearings and Appeals (OMHA) within 60 days of receiving the decision. If OMHA rejects your appeal, you can then appeal to the Medicare Appeals Council.
If the Appeals Council doesn’t support your claim, you can file a lawsuit with a federal district court having jurisdiction over your place of residence within 60 days of the Appeals Council’s rejection.
Challenging a pre-existing IRMAA decision without experiencing a significant life event may be a challenging appeal battle.
To avoid falling into the “trap” of IRMAA surcharges, it’s crucial to start planning before turning 65. Even being just $1 above the income threshold can push you into the next premium bracket.
Many retirees believed that holding Municipal Bonds or delaying withdrawals from retirement pensions would optimize their financial situation, only to still face paying IRMAA surcharges.
Forbes emphasizes the importance of tax planning before and during retirement. For instance, receiving a large bonus, selling a professional business, conducting a Roth IRA conversion, or similar financial operations without considering their tax implications might elevate your income and place you into a higher IRMAA tier.
Additionally, avoid withdrawing large sums of money at once from traditional individual retirement accounts (IRAs) or other tax-deferred accounts.
Converting to a Roth before reaching Medicare enrollment age, although it may increase your current taxable income, can help reduce future Required Minimum Distributions (RMDs) and mitigate the risk of facing IRMAA surcharges in the future.
If you are still employed, consider continuing contributions to a 401(k) or other tax-deferred retirement accounts and incorporate Medicare planning into overall tax planning.
