KEY POINTS
  • Monthly adjustments kick in next year for individuals with modified adjusted gross income above $91,000.
  • For married couples filing a joint tax return, that threshold is $182,000. 
  • Medicare enrollees with higher income have paid more for Part B since 2007 and for Part D since 2011.

Medicare beneficiaries who pay monthly surcharges for premiums may want to take note of how much more they'll be charged next year.

With the standard monthly premium for Part B (outpatient care coverage) now set at $170.10 for 2022, the so-called income-related monthly adjustment amounts, or IRMAAs, will result in higher-income beneficiaries paying anywhere from $238.10 to $578.30 each month for that coverage. About 7% of Medicare's 63.3 million beneficiaries with Part B will pay IRMAAs next year, according to the Centers for Medicare & Medicaid Services.
