SEE ALSO: Retirees, Avoid These 11 Costly Medicare Mistakes A small group of Medicare beneficiaries (about 3.5%) will pay less because the cost-of-living increase in their Social Security benefits is not large enough to cover the full premium increase. The “hold-harmless provision” prevents enrollees’ annual increase in Medicare premiums from exceeding their cost-of-living increase in Social Security benefits if their premiums are automatically deducted from their Social Security payments. Social Security benefits are increasing by 2.8% in 2019, which will cover the increase in premiums for most people. Premium increases are also minor for most higher-income beneficiaries—those with adjusted gross income plus tax-exempt interest income of more than $85,000 if single or $170,000 if married filing jointly. These beneficiaries already pay a high-income surcharge, but a new surcharge tier will kick in for 2019 for people with the highest incomes. Overall, monthly premiums for higher-income beneficiaries will range from $189.60 to $460.50 per person, depending on income.

Monthly premiums for singles with an income of $107,001 to $133,500 (joint filers with income of $214,001 to $267,000) will increase from $267.90 to $270.90. And premiums for singles earning $133,501 to $160,000 ($267,001 to $320,000 for joint filers) will rise from $348.30 to $352.20. If you had higher income than that, your monthly premium for 2018 was $428.60. In 2019, there will be an extra surcharge tier for people with the highest income. If your income is between $160,001 and $499,999 ($320,001 to $749,999 for joint filers), you’ll pay $433.40 per month. Single filers with income of $500,000 or more ($750,000 or more for joint filers) will pay $460.50 per month. High-income surcharges for 2019 are generally based on your 2017 income. If you’ve experienced certain life-changing events that have reduced your income since then, such as retirement, divorce or the death of a spouse, you can contest the surcharge.
