Medicare IRMAA Surcharge: A Hidden Cost for Retirees
The Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge added to Medicare Part B and Part D premiums for retirees with higher incomes. This surcharge is based on modified adjusted gross income (MAGI) from two years prior, which can catch retirees off guard. In 2026, the standard Part B premium is $202.90 per month, but it can increase significantly for those with higher MAGI. The surcharge can add thousands of dollars to annual healthcare costs, particularly affecting retirees who have not planned for this additional expense.
