A $1,580 lifetime annuity pushed a retiree’s Medicare premiums from $202.90 to $405.80 monthly due to IRMAA bracket changes.
A $1,580 monthly annuity lifted a 73-year-old retiree’s Modified Adjusted Gross Income (MAGI) across two IRMAA thresholds, doubling her Medicare Part B premium from $202.90 to $405.80. The increase, effective in 2026, adds roughly $2,900 in annual surcharges for Parts B and D.
The standard Part B premium was set at $185.00 in 2025 and rises to $202.90 in 2026. IRMAA surcharges apply when MAGI exceeds $109,000 for individuals, with higher brackets triggering additional costs. The retiree’s annuity income pushed her into a bracket where combined surcharges consume about 15% of her annual payout.
Retirees can mitigate IRMAA impacts by filing Form SSA-44 after income-reducing events or timing Roth conversions to stay below thresholds.
