The standard Part B premium amount in 2021 is $148.50 (or higher depending on your income). However, most people who get Social Security benefits pay less than this amount. This is because the Part B premium increased more than the cost-of-living increase for 2017 Social Security benefits. If you pay your Part B premium through your monthly Social Security benefit, you may pay less.  Social Security will tell you the exact amount you’ll pay for Part B.. You’ll pay the standard premium amount if:

• You enroll in Part B for the first time in 2017.
• You don’t get Social Security benefits.
• You’re directly billed for your Part B premiums OR YOU CAN SET UP MONTHLY AUTO PAY.
• You have Medicare and Medicaid, and Medicaid pays your premiums. (Your state will pay the standard premium.)
• Your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount. If so, you’ll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your premium.
