What it did to a Social Security payment

The Part B premium is withheld from the Social Security payment, so it lands in the same January as the cost-of-living adjustment and the two move against each other. A $2,000 monthly benefit in 2023 became $2,064 gross with the 3.2% adjustment — a rise of +$64. After the premium went from $164.90 to $174.70, the payment rose +$54, an effective 2.94%.

No income-related table is committed for 2024

The Federal Register notice for 2024 states the tier percentages in prose but publishes no bracket table, and this site does not hand-key a table it could not read from a primary source. The standard premium and deductible above are primary-sourced and complete. The coverage gaps are listed in full.
