MEDICARE PART B PREMIUM AMOUNTS

For Persons with Higher Income Levels.

The standard Part B premium amount in 2018 will be $134 (or higher depending on your income).

However, most people who get Social Security benefits will pay less than this amount. This is because the Part B premium increased more than the cost-of-living increase for 2018 Social Security benefits.

If you pay your Part B premium through your monthly Social Security benefit, you’ll pay less ($109 on average). Social Security will tell you the exact amount you will pay for Part B in 2018.

You’ll pay the standard premium amount 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.
  • 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.

Social Security will use the income reported two years ago on your IRS income tax return to determine your premium (if unavailable, SSA will use income from three years ago). For example, the income reported on your 2016 tax return will be used to determine your monthly Part B premium in 2018. If your income has decreased since 2017, you can ask that the income from a more recent tax year be used to determine your premium, but you must meet certain criteria.

The chart below shows the Part B monthly premium amounts based on income. These amounts change each year. There may be a late-enrollment penalty.
