Higher-income premiums in 2027
If your income is above certain levels, you pay an income-related monthly adjustment amount (IRMAA) on top of the standard Part B premium. For 2027, Social Security will look at your modified adjusted gross income from your 2025 tax return. The 2027 brackets come out with the CMS fact sheet. For 2026, the first bracket starts above $109,000 for single filers and $218,000 for joint filers.
What to do now
- Choosing a plan for 2027: Open Enrollment runs until December 7, 2026. Your Part B premium is the same whichever plan you pick, so you don't need the 2027 number to compare plans. Medicare Advantage members keep paying Part B too.
- Watch your mail: Social Security sends your 2027 benefit and premium amounts, usually in December, and online in your my Social Security account.
- If money is tight: Oregon's Medicare Savings Programs pay the Part B premium for people with limited income, with no asset limit.

Frequently asked questions
When will the 2027 Part B premium be announced?
CMS announces Part A and Part B amounts for the next year in a fact sheet, usually in the fall. The 2026 fact sheet came out on November 14, 2025. Social Security then lists your 2027 premium in your annual benefit notice.
Will my Part B premium be taken out of my Social Security check?
Yes, if you get Social Security benefits. A rule called hold harmless keeps most people's net Social Security payment from going down because of a Part B premium increase.
Which 2027 Medicare amounts are already known?
CMS has published the 2027 Part D out-of-pocket cap ($2,400) and maximum deductible ($700), and the highest in-network out-of-pocket limit a Medicare Advantage plan can set ($9,850).
