Medicare Part B rates will rise about 6% in the new year, with the base-level monthly premium moving from $174.70 in 2024 to $185 beginning in January.

That premium applies to Part B beneficiaries whose 2023 yearly income was $106,000 or less for an individual tax filer or $212,000 or less for married couples filing a joint return. Those with higher incomes from their 2023 taxes will pay an Income-Related Monthly Adjustment Amount (IRMAA) in addition to their base premium. There are five IRMAA brackets, with bracket income levels adjusted for inflation yearly.
