IRMAA
Definition
IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra amount added to your Medicare Part B and Part D premiums if your income is above certain thresholds.
More Detail
IRMAA is based on your reported income from two years prior. For example, your 2024 premiums are based on your 2022 tax return. The Social Security Administration notifies you if IRMAA applies to you. You have the right to appeal if your income has decreased since the base year due to a qualifying life event such as retirement, divorce, or death of a spouse.
