Medicare Part B Premium: What to Budget for the Upcoming Plan Year

The standard Medicare Part B premium is $202.90 per month in 2026. That premium generally continues whether you choose Original Medicare, Medigap, or Medicare Advantage. Here's what the 2026 Part B premium, IRMAA, and deductible mean for your Medicare budget.

Scenario: "I'm comparing zero-premium Advantage plans for January 2027. Is Part B still separate?"

Yes. Part B premium is federal. It follows you on Original Medicare and Advantage alike. A $0 Medicare Advantage plan premium does not mean you stop paying the Part B premium. If you're receiving Social Security benefits, the Part B premium is usually withheld from your monthly benefit. If you're not receiving Social Security, Medicare generally bills you directly.

CMS publishes official Part B amounts on Medicare.gov. When you stack finalists for January 2027, read how to read your ANOC alongside this post.

Check your Social Security letter if the Part B line looks higher than you expected. Read Medicare IRMAA income-related premiums for the surcharge tiers.

What is the Medicare Part B premium for 2026?#

The 2026 Part B annual deductible is $283.

Part B covers outpatient care: doctor visits, lab work, imaging, durable medical equipment, and most physician-administered drugs in office settings. After you meet the $283 annual Part B deductible, you generally pay 20% of the Medicare-approved amount for covered Part B services when you use providers who accept Medicare assignment. Medigap, Medicaid, or other coverage may help with that cost sharing.

Most beneficiaries pay the standard premium, according to CMS. Higher-income beneficiaries pay an additional IRMAA amount. Part B premium is federal. It does not vary by Florida versus North Carolina county the way Advantage rosters do.

I would not budget for Medicare using a neighbor's deposit amount. Compare your own Social Security award letter or Medicare bill. Giveback Advantage plans that reduce withholding still affect your Part B costs. Read the Evidence of Coverage for how the giveback interacts with your net deposit.

Who pays higher Part B premiums because of IRMAA?#

Households above CMS income thresholds pay income-related monthly adjustment amounts on top of the standard Part B premium.

For 2026 premiums, Social Security uses 2024 tax return modified adjusted gross income. Single filers with MAGI above $109,000 and joint filers above $218,000 enter the first IRMAA bracket. Higher brackets add larger surcharges. At the top IRMAA tier, total Part B including the standard premium plus maximum surcharge is listed in the CMS 2026 fact sheet.

IRMAA also applies to Part D for higher-income enrollees. A couple can face surcharges on both lines even if they never touch Advantage.

Social Security mails an Initial IRMAA Determination when IRS data triggers a tier. You may appeal with Form SSA-44 if your income dropped because of a life-changing event like retirement, divorce, or work stoppage. Approved appeals can reduce surcharges mid-year. Ignored determinations stick until Social Security receives updated data.

IRMAA uses income from two years back. You may have retired last year with lower income, but 2024 MAGI still drives 2026 premiums until an appeal or automatic update clears.

How is the Part B premium deducted from Social Security?#

Social Security withholds Part B automatically once you draw benefits; Medicare bills quarterly if you defer Social Security past 65.

Enrollment in Part B can start at 65 even when you delay Social Security. In that gap, Medicare sends quarterly bills for $202.90 times three months (plus IRMAA if applicable). Missing a bill risks coverage loss. Set up Medicare Easy Pay or mark due dates on your calendar.

Once Social Security starts, withholding replaces quarterly billing. Your net deposit drops by the premium amount. Many retirees notice the change before they connect it to Part B. Check the deductions section on your award letter rather than guessing from the headline deposit.

Railroad Retirement Board beneficiaries follow parallel rules with slightly different contact paths. If you work past 65 with employer coverage, Part B timing follows Medicare enrollment rules, not your Advantage shopping calendar.

Part B premium changes once per year in January for most people. Your Part B amount can change during the year if Social Security changes your IRMAA determination, approves a qualifying appeal, or receives updated information that changes the calculation. Switching Advantage carriers during AEP does not reset Part B premium. Only CMS and Social Security adjust that line.

Should I verify my doctors and pharmacy before choosing a plan?#

Yes. Part B premium is identical on Original Medicare and Advantage, but doctor access is not.

Medigap follows Medicare providers nationwide. Advantage restricts you to plan networks in your county. A $202.90 Part B bill feels the same either way. A denied specialist claim does not.

Before choosing a plan for January, verify must-keep doctors and pharmacies on the exact upcoming plan ID. Part D formularies change even when Part B premium stays flat. See how to verify your doctors on a Medicare Advantage plan for the call script billing offices expect.

Late enrollment penalties stack on top of Part B premium#

If you delay Part B without qualifying coverage through current employment, Medicare can charge a lifetime late-enrollment penalty on top of the standard premium. The penalty is generally 10% of the standard Part B premium for each full 12-month period of delayed enrollment when no qualifying Special Enrollment Period applies. It does not disappear when you finally sign up.

If you delayed Part B because you had coverage through your own or a spouse's current employment, keep documentation showing the employment and group health coverage. That information may be needed when you use a Part B Special Enrollment Period. COBRA does not extend the Part B Special Enrollment Period. If you rely on COBRA after active employment ends and delay Part B beyond your applicable enrollment period, you could face a late-enrollment penalty.

Part B premium and late penalties are separate from IRMAA. You can owe standard premium plus penalty plus IRMAA simultaneously. Social Security withholds all three from the same deposit when applicable.

Giveback plans and your award letter#

Some Advantage contracts advertise a Part B giveback that reduces Social Security withholding. The giveback amount varies by plan and county. The reduction is applied through the way your Medicare premium is collected; it is not separate cash in your bank account.

I would read the Summary of Benefits giveback row next to specialist copays before assuming the plan is cheaper overall. A $100 monthly giveback should be weighed against the plan's other costs, including the medical out-of-pocket maximum, specialist copays, imaging costs, and other services you expect to use.

How Part B premium fits next to Advantage and Medigap#

Every path keeps Part B:

Medigap Plan G and Plan N do not replace Part B premiums. They cover Medicare cost sharing after Medicare pays its share. Advantage replaces Original Medicare cost sharing with plan copays and a medical out-of-pocket maximum. Compare total annual exposure, not just the plan premium row.
