What Does Income Related Monthly Adjustment Amount (IRMAA) Address?

 The Medicare Income-Related Monthly Adjustment Amount is an amount you may pay in addition to your Part B and/or Part D premium if your income is above a certain level. The Social Security Administration (SSA) sets income brackets that determine your (or you and your spouse’s) IRMAA. SSA determines if you owe an IRMAA based on the income you reported on your IRS tax returns two years prior, meaning two years before the year that you started paying IRMAA. The income that counts is the adjusted gross income you reported plus other forms of tax-exempt income.

 If you are expected to pay an IRMAA, SSA will notify you that you have a higher Part B premium.
