The income-related monthly adjustment amount (IRMAA) sliding scale is a set of statutory
percentage-based tables used to adjust Medicare Part B-ID coverage premiums. The higher
the beneficiary’s range of modified adjusted income (MAGI), the higher the IRMAA.
The following are the 2024 Part B-ID monthly premium rates to be paid by (or on behalf
of) beneficiaries who file individual tax returns (including those who are single,
heads of households, qualifying surviving spouse(s) with dependent children, or married
individuals filing separately who lived apart from their spouses for the entire taxable
year) or joint tax returns
