Medicare Part B in 2026: Costs, Enrollment, and Ways to Save

Medicare Part B covers doctor visits, outpatient care, and preventive services — but many people have questions about what it costs, how to sign up, and whether help is available if the premium is a strain. Here are direct answers to the most common Medicare Part B questions for 2026, using current figures from CMS and Medicare.gov.

How Much Does Medicare Part B Cost in 2026?

The standard Medicare Part B premium is $202.90 a month in 2026, up from $185.00 in 2025, according to CMS. The annual Part B deductible is $283 in 2026 (up from $257 in 2025). After you meet the deductible, Original Medicare generally pays 80% of the Medicare-approved amount for covered services, and you pay the remaining 20% coinsurance.

Do I Have to Sign Up for Part B, or Is It Automatic?

It depends. If you’re already receiving Social Security or Railroad Retirement benefits when you turn 65, you’re typically enrolled in Part B automatically. If you’re not yet collecting those benefits, you’ll need to actively sign up during your Initial Enrollment Period — the 7-month window around your 65th birthday.

How Is My Part B Premium Actually Paid?

For most people, the premium is deducted automatically from Social Security, Railroad Retirement, or Office of Personnel Management benefit payments. If you don’t receive any of those benefits, Medicare will send you a bill directly.

Will I Pay More Than the Standard Premium?

You will if your income is above a certain threshold. Medicare uses your tax return from two years earlier (2024 income determines your 2026 premium) to calculate an Income-Related Monthly Adjustment Amount, or IRMAA — an extra amount added on top of the standard premium. Here’s the 2026 IRMAA schedule for individual and joint filers, per CMS:

• Individual income up to $109,000 / Joint up to $218,000: $202.90/month (standard premium, no surcharge)
• Individual $109,001–$137,000 / Joint $218,001–$274,000: $284.10/month
• Individual $137,001–$171,000 / Joint $274,001–$342,000: $405.80/month
• Individual $171,001–$205,000 / Joint $342,001–$410,000: $527.50/month
• Individual $205,001–$499,999 / Joint $410,001–$749,999: $649.20/month
• Individual $500,000+ / Joint $750,000+: $689.90/month

Can My Part B Premium Be Adjusted If My Income Recently Dropped?

Yes. If you’re paying an IRMAA surcharge but have since had a “life-changing event” — such as retirement, work reduction, divorce, marriage, or the death of a spouse — you can ask the Social Security Administration to use more recent income instead of the two-year-old tax return. You do this by filing Form SSA-44 along with documentation of the event and your updated income. You can also call Social Security at 1-800-772-1213 to ask about your specific situation.

Is There a Penalty for Signing Up Late?

Yes, and it’s important to understand because — unlike some other penalties — this one is generally permanent. If you don’t sign up for Part B when you’re first eligible and don’t qualify for a Special Enrollment Period (for example, because you had coverage through an employer), your premium can increase by 10% for each full 12-month period you could have had Part B but didn’t, according to Medicare.gov. For example, someone who waited two full years to enroll would pay a 20% penalty on top of the standard premium — an extra $40.58 a month in 2026, added to their premium for as long as they have Part B.

Can New York State Help Pay My Part B Premium?

Yes, if your income falls within certain limits. New York’s Medicare Savings Programs (MSP) can pay your Part B premium for you, and New York has no asset limit for these programs — a benefit not every state offers, according to the New York State Department of Health. As of 2026, the general monthly income guidelines are:

• QMB (Qualified Medicare Beneficiary): up to about $1,856/month individual, $2,509/month for couples — pays your Part B premium plus deductibles and coinsurance.
• QI (Qualifying Individual): up to about $2,494/month individual, $3,375/month for couples — pays your Part B premium only.

Enrolling in a Medicare Savings Program also permanently eliminates any Part B late enrollment penalty you might otherwise owe, and it automatically qualifies you for Extra Help with Part D prescription drug costs. Since these income figures can shift slightly each year, it’s worth confirming your exact eligibility with New York’s Medicaid Helpline at 1-800-541-2831 or with a licensed advisor.

What You Should Do Now

• Confirm your enrollment status — check whether you’re automatically enrolled in Part B or need to sign up during your Initial Enrollment Period to avoid a penalty.
• Check if you qualify for a Medicare Savings Program if your income is limited — this can eliminate your Part B premium entirely.
• File Form SSA-44 if a life-changing event has lowered your income since the tax year used to calculate your IRMAA.
• Talk to a licensed advisor to see how your Part B costs fit into your overall Medicare picture, including whether a Medicare Advantage or Medigap plan makes sense for your situation.

Frequently Asked Questions

What is the 2026 Medicare Part B deductible?

The 2026 Part B deductible is $283 per year. Once you’ve paid that amount out of pocket for Part B-covered services, Medicare generally pays 80% of the approved amount for the rest of the year.

What counts as a “life-changing event” for lowering my IRMAA?

The Social Security Administration recognizes marriage, divorce or annulment, death of a spouse, work stoppage or reduction, loss of income-producing property, loss of pension income, and receipt of an employer settlement payment.

Does the Part B late enrollment penalty ever go away?

In most cases, no — it’s added to your premium for as long as you have Part B. The one major exception is enrolling in a Medicare Savings Program, which eliminates the penalty going forward.
