How Much for Medicare Part B in 2026: Premiums and Costs
Overview of Medicare Part B in 2026
Medicare Part B is a crucial part of Original Medicare, providing coverage for outpatient medical care, doctor visits, preventive services, and crucial medical equipment. For 2026, beneficiaries will encounter notable updates: the standard monthly premium rises to $202.90, an increase from $185.00 in 2025. The annual deductible also increases, now set at $283. These adjustments reflect ongoing changes in health care costs, service utilization, and inflation.
The Social Security Administration (SSA) determines your exact premium primarily based on your Modified Adjusted Gross Income (MAGI), using tax information from 2024. Around 8% of beneficiaries will face higher costs due to income surcharges called Income-Related Monthly Adjustment Amount (IRMAA). Premium calculations, late enrollment penalties, and the rules regarding notifications are all essential considerations for those planning their Medicare budget.

Standard Monthly Premium and Deductible
The 2026 Medicare Part B standard monthly premium is $202.90 for most enrollees. This is a $17.90 increase over the previous year, aligned with rising medical service costs and inflation adjustments. The annual deductible-the out-of-pocket amount you must pay before Medicare coverage kicks in-also sees a hike, up to $283 for 2026. These figures are publicly announced each fall by the Centers for Medicare & Medicaid Services (CMS).
Beneficiaries already enrolled in Medicare and receiving Social Security may pay a lower premium if their Social Security cost-of-living adjustment (COLA) would otherwise be offset by the premium increase. This hold harmless provision helps shield enrollees from disproportionate jumps in out-of-pocket expenses.
Income-Related Monthly Adjustment Amount (IRMAA)
The standard premium applies to the majority of Medicare enrollees. However, higher-income individuals are subject to the Income-Related Monthly Adjustment Amount (IRMAA), a surcharge added to the base premium. The IRMAA is calculated based on your MAGI from your 2024 IRS tax return, and it adjusts each year to account for inflation and overall national income levels.
IRMAA surcharges for Medicare Part B in 2026 range from $81.20 to $487.00 per month, depending on your income bracket. That means some beneficiaries could pay between $284.10 and $689.90 each month for Part B coverage. Your official IRMAA determination and notice will come from the SSA, usually at the end of each year.

2026 Medicare Premiums by Income Bracket
Table: 2026 Part B Premiums by Filing Status
| MAGI (Individual) | MAGI (Married Filing Jointly) | IRMAA Surcharge | Total Monthly Premium |
|---|---|---|---|
| ≤ $109,000 | ≤ $218,000 | $0 | $202.90 |
| > $109,000 – $137,000 | > $218,000 – $274,000 | $81.20 | $284.10 |
| > $137,000 – $171,000 | > $274,000 – $342,000 | $202.90 | $405.80 |
| > $171,000 – $205,000 | > $342,000 – $410,000 | $324.60 | $527.50 |
| > $205,000 – $500,000 | > $410,000 – $750,000 | $446.30 | $649.20 |
| > $500,000 | > $750,000 | $487.00 | $689.90 |
As an example, if your individual MAGI was $150,000 in 2024, you would pay the $202.90 standard premium plus a $202.90 IRMAA surcharge for a total of $405.80 each month in 2026.
This structure ensures that higher-income enrollees contribute more, helping maintain Medicare’s sustainability. To see how this premium structure compares to previous years, keep in mind that each fall, CMS announces adjustments reflecting changes in costs and utilization and inflation impacts.

Premiums for Married Filing Separately
Beneficiaries who are married but file taxes separately face different brackets for IRMAA. This often results in much higher surcharges sooner, especially if you lived with your spouse at any time during the year. See the table below for 2026 amounts:
| MAGI (Married Filing Separately) | IRMAA Surcharge | Total Monthly Premium |
|---|---|---|
| ≤ $109,000 | $0 | $202.90 |
| > $109,000 – $391,000 | $446.30 | $649.20 |
| ≥ $391,000 | $487.00 | $689.90 |
For example, a beneficiary married but filing separately with MAGI over $391,000 will pay the highest IRMAA surcharge, reaching $689.90 per month.
How and When Premiums Are Paid
The vast majority of Medicare beneficiaries have their Part B monthly premium automatically deducted from their Social Security, Railroad Retirement, or federal civil service retirement benefits. This helps ensure consistent coverage and avoids missed payments. For those not yet drawing retirement benefits, the Centers for Medicare & Medicaid Services (CMS) will bill you quarterly, or you may opt for monthly electronic payment options by mail or direct debit.
The Social Security notification process is important: each November or December, SSA will mail a letter specifying your upcoming Part B premium, including any IRMAA or penalty. New enrollees typically pay the standard rate at first, with income assessed once tax data is received. Payments are required before January 2026 coverage starts-failure to pay can result in loss of Part B benefits.

Late Enrollment Penalties Explained
If you do not sign up for Medicare Part B during your Initial Enrollment Period-which starts three months before you turn 65 and ends three months after your 65th birthday-or if you go without other creditable health insurance, you will incur a late enrollment penalty. This penalty increases your monthly premium by 10% for every full 12-month period you were eligible but didn’t enroll.
Importantly, the late enrollment penalty is permanent. For example, if you delayed enrollment by two full years, your premium would be 20% higher for as long as you remain on Part B. This can significantly add up over time. Those who qualify for a Special Enrollment Period-such as after losing employer-sponsored health insurance-can enroll without incurring a penalty during specific windows.
Annual Enrollment runs from October 15 to December 7 each year. If you plan on changing coverage or enrolling for the first time, it’s vital to review your situation early to avoid unexpected penalties or lapses in coverage.

Frequently Asked Questions
- What income counts for IRMAA? Social Security and CMS use your Modified Adjusted Gross Income (MAGI), which includes your Adjusted Gross Income plus tax-exempt interest, non-taxable Social Security benefits, and some specific add-backs. This determines your income-related premium bracket and any necessary IRMAA surcharge.
- Can I appeal IRMAA? Yes. If you experience a qualifying life-changing event such as retirement, divorce, marriage, or certain natural disasters that lead to a significant drop in income, you can appeal the IRMAA determination with SSA within 60 days of receiving your notice.
- Does the Part B premium affect my Part D? Yes, income brackets for Medicare Part B and Part D are the same. Higher-income enrollees will pay a Part D IRMAA surcharge ranging from $14.50 to $91.00 per month, in addition to their plan’s regular premium. For more information, see How Does Medicare Part D Work? Prescription Drug Coverage Explained.
- Will premiums rise more in the future? Medicare premiums and deductibles are set annually by CMS based on national health care costs and program utilization. The 2026 increases reflect a jump of nearly 10% over prior years, with further changes possible as health care expenses fluctuate. Stay updated by regularly consulting reliable sources and reviewing your annual SSA notice.
