The IRMAA Income Trap Quiz: What Really Counts?

For many retirees, the realization that “tax-free” doesn’t always mean “cost-free” comes as a shock when their Medicare premiums arrive. The Income-Related Monthly Adjustment Amount (IRMAA) is a surcharge that can significantly increase your health care costs based on how you manage your wealth.

Because Medicare uses a specific calculation — Modified Adjusted Gross Income (MAGI) — certain common financial moves, like selling a home or collecting municipal bond interest, can unexpectedly push you into a higher bracket. This 10-question quiz is designed to help you navigate these nuances, ensuring your legacy and lifestyle aren’t sidelined by avoidable surcharges.
