Understanding IRMAA in 2025: What Medicare Beneficiaries Need to Know

Are you approaching Medicare eligibility or currently enrolled? You might have encountered the term IRMAA—Income-Related Monthly Adjustment Amount. This guide provides essential information about IRMAA, how it's calculated, who pays it, and the current income brackets for 2025.
What is IRMAA?
IRMAA stands for Income-Related Monthly Adjustment Amount. It's an additional surcharge that higher-income Medicare beneficiaries pay on top of the standard Medicare Part B (medical insurance) and Medicare Part D (prescription drug coverage) premiums. This surcharge is based on your modified adjusted gross income (MAGI).
How is IRMAA Calculated?
Your IRMAA payment is determined using your income reported from two years earlier. For instance, your 2025 IRMAA is calculated based on your 2023 tax return. The Social Security Administration (SSA) evaluates your income information annually and sends notifications if you're subject to IRMAA surcharges.
Who Needs to Pay IRMAA?
IRMAA affects individuals and couples whose incomes surpass specific thresholds. Generally, higher-income Medicare beneficiaries must pay this surcharge. If your MAGI exceeds these thresholds, you will receive an official notice from the SSA.

When is IRMAA Paid?
Typically, IRMAA payments are deducted directly from your Social Security check if you are receiving benefits. If you are not receiving benefits, Medicare will bill you directly. Payments are monthly and align with your standard Medicare premium schedule.
What If Your Income Changes?
Life changes such as retirement, divorce, or loss of a spouse can significantly affect your income. If this occurs, you may appeal your IRMAA determination to the SSA for a reassessment.
