Cost of Medicare Part B
Medicare Part A is free for most people.
If you elect to choose Part B as well, then you’ll have to pay a monthly premium.
If you are already collecting benefits from the Social Security Administration, the Railroad Retirement Board or the Office of Personnel Management, then your Part B premium will automatically be deducted from your monthly benefits.
If you are not receiving any of these forms of income, then you will get a bill.
How is My Medicare Part B Cost Calculated?
Most people will pay the standard premium amount.
If your modified adjusted gross income is above a certain amount, you may pay an Income Related Monthly Adjustment Amount (IRMAA).
Medicare uses the modified adjusted gross income reported on your IRS tax return from 2 years ago.
This is the most recent tax return information provided to Social Security by the IRS.
Income Related Monthly Adjustment Amount (IRMAA)
The standard Part B premium amount in 2020 is $144.60.
Most people pay the standard Part B premium amount.
If your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount, you’ll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA).
