It can. If you are what Social Security considers a “higher-income beneficiary,” you pay more for Medicare Part B, the health-insurance portion of Medicare. (Most enrollees don’t pay for Medicare Part A, which covers hospitalization.)

Medicare premiums are based on your modified adjusted gross income, or MAGI. That’s your total adjusted gross income plus tax-exempt interest, as gleaned from the most recent tax data Social Security has from the IRS. To set your Medicare cost for 2023, Social Security will likely rely on the tax return you filed in 2022 that details your 2021 earnings.

If your MAGI for 2021 was less than or equal to the “higher-income” threshold — $97,000 for an individual taxpayer, $194,000 for a married couple filing jointly — you will pay the “standard” 2023 Part B rate of $164.90 a month. At higher incomes, premiums rise, to a maximum of $560.50 a month if your MAGI exceeded $500,000 for an individual, $750,000 for a couple.

You can ask Social Security to adjust your premium if a “life-changing event” caused significant income reduction or financial disruption in the intervening tax year — for example, if your marital status changed, or you lost a job, pension or income-producing property.

You’ll find detailed information on the Social Security web page “Medicare Premiums: Rules for Higher-Income Beneficiaries.”


  • If you pay a higher premium, you are not covered by “hold harmless,” the rule that prevents most Social Security recipients from seeing their benefit payment go down if Medicare rates go up. “Hold harmless” only applies to people who pay the standard Part B premium and have it deducted from their Social Security benefit.
  • Premiums for Medicare Part D (prescription-drug coverage), if you have it, also rise with higher incomes.
