The premium you pay for Medicare Part B and Part D is dependent on your income. Medicare Income-Related Monthly Adjustment Amount (IRMAA) is the name for the income adjusted amount you pay for Medicare Part B or Part D premiums and is determined by your income. Below is a chart that details the various premiums based on your income.
