2025 tax returns set 2027 Medicare premiums
The 2025 tax return filed in April has set the 2027 Medicare premiums, with married couples paying every IRMAA surcharge twice.
This can push combined monthly Part B costs from $203 up to $974 per tier crossed.
A couple who converted $120,000 from a traditional IRA to a Roth in 2025 will see their 2027 Medicare premiums reset, with no option to undo it.
