Part B Premium

The standard Part B premium amount in 2018 will be $134 (or higher depending on your income). However, some people who get Social Security benefits pay less than this amount ($130 on average). You’ll pay the standard premium amount (or higher) if:

  • You enroll in Part B for the first time in 2018.
  • You don’t get Social Security benefits.
  • You’re directly billed for your Part B premiums (meaning they aren’t taken out of your Social Security benefits).
  • You have Medicare and Medicaid, and Medicaid pays your premiums. (Your state will pay the standard premium amount of $134.)
  • 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.
