Question 1

What is IRMAA and why do I have to pay it?

Accepted Answer

IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to Medicare Part B and Part D premiums for high-income beneficiaries. It is based on your Modified Adjusted Gross Income (MAGI) from 2 years prior, as reported on your tax return.

Question 2

Can I appeal my IRMAA surcharge?

Accepted Answer

Yes, you can appeal IRMAA if you experienced a life-changing event that significantly reduced your income. Qualifying events include retirement, job loss, divorce, death of spouse, or loss of income-producing property. File form SSA-44 with documentation.

Question 3

What form do I use for IRMAA appeal?

Accepted Answer

Use SSA-44 (Request for New Initial Determination). Submit it to Social Security with proof of the life-changing event and documentation of your current, lower income. SSA may recalculate IRMAA based on your current income.

Question 4

What income is used for IRMAA determination?

Accepted Answer

SSA uses your Modified Adjusted Gross Income (MAGI) from 2 years prior. For 2024 IRMAA, SSA uses your 2022 tax return data. MAGI = AGI + tax-exempt interest + foreign earned income exclusion.
