Most Americans pay the standard Medicare Part B monthly premium, but those with income over a certain threshold also pay an Income Related Monthly Adjusted Amount (IRMAA). IRMAA is a surcharge for high earners that is based on your Modified Adjusted Gross Income (MAGI) from two years ago.

The best way to avoid IRMAA is, of course, to keep your MAGI down. And the best way to do that is through careful tax planning and an intentional retirement withdrawal strategy.
