Quick Answer: The standard Medicare Part B premium for 2026 is $202.90 a month, up from $185.00 in 2025. Most people pay this exact amount. Higher-income beneficiaries pay more through a surcharge called IRMAA, which can push the total as high as $689.90 a month. Lower-income beneficiaries may qualify for a Medicare Savings Program that covers the premium entirely, effectively making Part B free.
Few numbers in Medicare get asked about as often as the Part B premium, and this year there’s good reason: the 2026 increase, from $185.00 to $202.90, is one of the larger jumps in recent memory. If you’ve seen that number and wondered why you’re paying more, less, or something entirely different, you’re not alone.
The truth is the Part B premium isn’t one number. It’s a starting point that can move in either direction depending on your income, your enrollment timing, and whether you qualify for assistance. Below, I’ll break down exactly what determines what you’ll actually pay in 2026.
What Is the Standard Medicare Part B Premium for 2026?
The standard Medicare Part B premium for 2026 is $202.90 per month, an increase of $17.90, or about 9.7%, from the 2025 premium of $185.00. This is the amount most Medicare beneficiaries pay, and it’s typically deducted directly from your Social Security benefit each month.
Alongside the premium increase, the annual Part B deductible rose to $283 for 2026, up from $257. Once you meet that deductible, Part B generally covers 80% of the Medicare-approved amount for covered services, leaving you responsible for the remaining 20% coinsurance, with no annual out-of-pocket cap under Original Medicare.
Why Did the Premium Increase So Much This Year?
Part B premiums are set annually based on projected program costs, and 2026’s increase reflects rising healthcare spending across the Medicare program. While increases happen most years, this year’s jump is larger than the typical annual adjustment, which is part of why it’s generating more questions than usual.
Why Might You Pay More Than $202.90?
If your income is above a certain threshold, you’ll pay an Income-Related Monthly Adjustment Amount, or IRMAA, on top of the standard premium. IRMAA is based on your modified adjusted gross income (MAGI) from two years earlier, meaning your 2026 premium is determined by your 2024 tax return.
The 2026 IRMAA Brackets
| 2024 MAGI (Single) | 2024 MAGI (Married Filing Jointly) | Total Monthly Part B Premium |
| $109,000 or less | $218,000 or less | $202.90 |
| $109,001 to $137,000 | $218,001 to $274,000 | $284.10 |
| $137,001 to $171,000 | $274,001 to $342,000 | $405.80 |
| $171,001 to $205,000 | $342,001 to $410,000 | $527.50 |
| $205,001 to $499,999 | $410,001 to $749,999 | $649.20 |
| $500,000 or more | $750,000 or more | $689.90 |
IRMAA isn’t marginal the way income tax brackets are. Once your MAGI crosses into a tier, the surcharge for that entire tier applies to your full premium, not just the income above the threshold. If your income has dropped since 2024 due to retirement, divorce, or another qualifying life event, you can request a redetermination using Form SSA-44 rather than simply accepting the higher premium.
Can You Get Medicare Part B for Free?
Not entirely free in the sense of a $0 premium being standard, but for lower-income beneficiaries, Medicare Savings Programs can effectively eliminate it. The most generous of these, Qualified Medicare Beneficiary (QMB), pays your Part B premium along with your Part A premium if you owe one, plus your Medicare deductibles, coinsurance, and copays.
In 2026, QMB generally applies to individuals with monthly income up to around $1,350 and couples up to around $1,824, though exact limits vary by state. Two other programs, Specified Low-Income Medicare Beneficiary (SLMB) and Qualifying Individual (QI), cover just the Part B premium for people with somewhat higher incomes, up to roughly $1,816 a month for an individual under QI.
A Real Scenario Worth Considering
Say you’re in Tulsa living on a fixed Social Security income and the Part B premium increase this year is stretching your budget. If your monthly income falls under the QMB or SLMB thresholds, applying through the Oklahoma Health Care Authority could eliminate your Part B premium entirely, turning a real budget pressure into one less bill each month.
What Happens If You Enroll in Part B Late?
If you don’t sign up for Part B during your Initial Enrollment Period and don’t qualify for a Special Enrollment Period, usually tied to active employer coverage, you’ll face a late enrollment penalty: a permanent 10% increase to your premium for every full 12-month period you were eligible but didn’t enroll.
This penalty is calculated on the current year’s standard premium and applies for as long as you have Part B, which, in practice, usually means for the rest of your life. Two years of delay means a 20% permanent increase; five years means 50%, adding over $100 to your monthly premium indefinitely at 2026 rates.
A Trade-Off Worth Understanding
The decision to delay Part B often makes sense if you’re still working and covered by a qualifying employer group health plan. It rarely makes sense otherwise. The penalty is calculated in whole years, so even an 11-month gap carries no penalty, while a 13-month gap triggers a full 10% increase for life, which is why timing this correctly matters more than most people expect.
How Do You Figure Out What You’ll Actually Pay?
Your real Part B cost depends on three questions: what did your income look like two years ago, did you enroll on time, and do you qualify for assistance based on current income. Those three answers, not the $202.90 headline figure, determine your actual monthly bill.
