Medicare Income-Related Monthly Adjustment Amount (IRMAA) is an amount that Medicare recipients pay in addition to their regular Part B or Part D premium if their income is above a certain level. The Social Security Administration (SSA) sets income brackets that determine your surcharges. SSA determines if you owe an IRMAA based on the income you reported on your IRS tax return two years prior (2019 IRMMA surcharges are based on your 2017 tax return). The income that counts is the adjusted gross income you reported plus other tax-exempt income. With married couples who file a joint return, the IRMMA surcharges are per person.
