What is the Income-Related Monthly Adjustment Amount (IRMAA)?
The income-related monthly adjustment amount (IRMAA) is an extra premium added onto some peoples’ Medicare Part B premiums. Individuals who have higher incomes get the privilege of paying the additional cost.
Whether or not you pay the higher premium amount is based on your modified adjusted gross income (MAGI).
Most people on Medicare Part B pay 25% of the premiums and the government pays the other 75%. Individuals who earn more money and are subject to IRMAA have to pay more for Medicare Part B premiums equal to 35%, 50%, 65%, 80%, or 85% of the total cost, depending on what they report to the Internal Revenue Service (IRS).
When is the Medicare Open Enrollment Period?
