Question 1

What is IRMAA?

Accepted Answer

IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra charge added to your Medicare Part B and Part D premiums when your income is above a set threshold.

Question 2

How is MAGI calculated?

Accepted Answer

Modified Adjusted Gross Income (MAGI) is your Adjusted Gross Income plus any tax-exempt interest income. Social Security uses MAGI to determine whether IRMAA applies.

Question 3

Why does Medicare use income from two years ago?

Accepted Answer

Social Security generally uses the most recent federal tax return available, which is from two years earlier. For 2026 premiums, that is usually your 2024 tax return.

Question 4

Can IRMAA be appealed?

Accepted Answer

Yes. If a life-changing event reduced your income, you can request a reconsideration by filing Form SSA-44 with Social Security.

Question 5

What life events qualify for reconsideration?

Accepted Answer

Qualifying events include marriage, divorce, death of a spouse, work stoppage or reduction such as retirement, loss of pension, and loss of income-producing property.

Question 6

Does everyone pay IRMAA?

Accepted Answer

No. Most people pay only the standard Part B premium. IRMAA applies only to higher-income beneficiaries above the annual income thresholds.
