Medicare Part B Costs in 2026: What the Increase Means for Your Social Security Payment
Last Updated on September 16, 2026
Jurisdiction: United States. Figures checked 28 July 2026.
For most people enrolled in Medicare Part B, the standard monthly premium is $202.90 in 2026. That is $17.90 more than the 2025 premium of $185. The annual Part B deductible has also risen, from $257 to $283.
Those increases matter because most people receiving Social Security have their Part B premium deducted directly from their monthly benefit. However, a higher Medicare premium does not automatically mean your Social Security deposit will shrink. The result depends on your benefit, your premium and any other deductions.
The 2026 figures at a glance
- Standard Part B monthly premium: $202.90
- Annual Part B deductible: $283
- Monthly premium increase from 2025: $17.90
- Annual deductible increase from 2025: $26
The standard premium applies to most beneficiaries. Medicare says roughly 8% of Part B enrollees pay an income-related surcharge known as IRMAA.
Will your Social Security payment be lower?
Not necessarily. Social Security benefits and Medicare premiums are calculated separately. If your cost-of-living adjustment adds more to your benefit than the increase in your Part B deduction, your net payment may still rise.
A Social Security protection commonly called the hold-harmless provision may prevent the standard Part B premium increase from reducing some beneficiaries’ net Social Security payment below the previous year’s amount. It does not protect everyone, and it does not generally shield people from IRMAA, Part D premiums or other deductions.
Your annual benefit notice should show your gross Social Security benefit, Medicare deductions and final net payment. Compare the notice with your first payment rather than relying on a general example, because even two neighbours with identical Medicare cards can receive different net amounts.
Why some people pay more than $202.90
Higher-income beneficiaries pay IRMAA in addition to the standard premium. For 2026, the standard premium applies when modified adjusted gross income is no more than $109,000 for an individual tax return or $218,000 for a joint return. Above those levels, total monthly Part B premiums range from $284.10 to $689.90, depending on income and filing status.
Social Security normally uses income from a tax return filed two years earlier. That can create a nasty surprise for someone whose income has fallen sharply since retiring.
Can you ask Social Security to reduce IRMAA?
Possibly. If the tax return being used no longer reflects your finances because of a qualifying life-changing event, you can ask Social Security to make a new determination. Events may include retirement or reduced work, marriage, divorce, the death of a spouse, loss of income-producing property, loss of pension income or an employer settlement payment.
Form SSA-44 explains the process and the supporting documents required. Do not assume the adjustment will happen automatically.
Four sensible checks for 2026
- Read your Social Security notice. Confirm the gross benefit, Part B deduction and net amount.
- Check whether IRMAA applies. Look at the income year Social Security used and consider whether a qualifying event has changed your circumstances.
- Review other costs separately. Medicare Advantage, Medigap and Part D premiums are not included in the standard Part B premium.
- Ask promptly if something looks wrong. Social Security handles Part B premium deductions and IRMAA decisions; Medicare can explain coverage and plan issues.
If Medicare costs are difficult to afford
Medicare Savings Programs may help eligible people pay Part A or Part B premiums and, in some cases, deductibles, coinsurance and copayments. Eligibility rules and income limits vary by state. The official Medicare Savings Programs page explains the four programs and how to contact your state.
State Health Insurance Assistance Programs also provide free, impartial Medicare counselling. You can locate yours through SHIP Help.
Make this an annual check
Medicare premiums, deductibles and income thresholds change each year. Treat any article quoting a dollar figure as dated information, even when the general explanation remains useful. Keep your current Medicare handbook and latest Social Security notice together. It is less exciting than spending the children’s inheritance, admittedly, but it can prevent expensive misunderstandings.
