Understanding IRMAA

The income-related monthly adjustment amount (IRMAA) is a fee you pay on top of your Medicare Part B and Part D premiums if you make a yearly income above the annual thresholds.

What is IRMAA?
The Medicare income-related monthly adjustment amount (IRMAA) is a surcharge on Medicare Part B (medical insurance) and Part D prescription drug plan premiums. It applies only to Medicare beneficiaries with a modified adjusted gross income above $103,000 (individual return) or $206,000 (joint return).

How is IRMAA calculated?
The Medicare IRMAA for Part B and Part D is based on your income and is calculated on a sliding scale. When determining whether IRMAA applies to you, Medicare uses the adjusted gross income amount reported on your tax return from two years prior.

What are the income limits for IRMAA?

IRMAA applies in 2024 if your modified adjusted gross income from 2022 is above these thresholds:


Filing individuallyIncome > $103,000
Married filing jointlyIncome > $206,000
Married filing separatelyIncome > $103,000


Is IRMAA based on gross income or taxable income?
Your IRMAA amount is determined based on the modified adjusted gross income (MAGI) from your tax return two years ago.

Do capital gains count toward IRMAA?
Yes, since capital gains are included in MAGI, they can affect your IRMAA.

Do Social Security benefits count toward IRMAA?
Yes, the taxable portion of your Social Security benefits is used to calculate your MAGI, and MAGI determines your IRMAA.
