Yes, Medicare Part B premiums are paid in advance. The premium you pay each month covers the following month’s coverage, not the month you are currently in. This billing structure catches many beneficiaries off guard, especially those who assume their payment covers the same month it is deducted or billed.
Under 42 U.S.C. § 1395r, the Secretary of Health and Human Services sets the standard Part B premium each year. For 2026, CMS announced the standard monthly premium is $202.90, up from $185.00 in 2025. About 57 million Americans rely on Medicare Part B for outpatient services, lab work, and preventive care. A missed or late premium payment can trigger a cascade of consequences, from delinquency notices to outright termination of coverage.

What “Paid in Advance” Means for Medicare Part B
Medicare Part B premiums work differently from most bills you pay. When you pay rent or a utility bill, you typically pay for the month you just used. Medicare flips that around. Your Part B premium payment covers the next month’s medical coverage.
If your premium is deducted from your Social Security check in August, that deduction pays for your September Part B coverage. Social Security benefits themselves are paid in arrears, meaning the check you receive in August is actually for July’s retirement benefits. This creates a timing mismatch that confuses many people.
The reason Medicare bills in advance is straightforward. The Centers for Medicare & Medicaid Services (CMS) needs to confirm your coverage is funded before you use medical services in a given month. If you receive care in September, Medicare needs your premium paid before September starts.
Think of it like a streaming subscription. Netflix charges you before you watch anything that month. Medicare works the same way — it collects the premium before providing coverage.
How the Billing Timeline Works
Medicare bills are due on the 25th of the month. In most cases, the premium is due the same month you receive the bill. The payment you submit covers coverage for the following month.
If you pay Part B only and are not receiving Social Security benefits, you receive a bill from Medicare every three months. That quarterly bill covers three upcoming months of coverage. If you also pay Part A premiums or a Part D IRMAA surcharge, you receive a monthly bill instead.
| Billing Situation | How Often You Get a Bill |
|---|---|
| Part B only (no Social Security benefits) | Every 3 months |
| Part A premium | Every month |
| Part D IRMAA surcharge | Every month |
| Receiving Social Security benefits | Auto-deducted monthly |
Medicare Easy Pay users also receive a monthly automatic deduction. The billing frequency matters because it determines how much cash you need available at any given time. Quarterly billing means larger lump-sum payments, while monthly billing spreads the cost more evenly.
Why Your First Bill Looks Higher Than Expected
New enrollees are often surprised by their first Medicare bill. If you applied for Part B to start in August, you will receive a bill in July covering your August, September, and October premiums. That means your first payment includes three months of premiums at once.
This happens because Medicare bills Part B in quarterly cycles for people who do not receive Social Security. The first bill arrives one month before coverage begins. Your next bill will not arrive until three months later.
At the 2026 standard premium of $202.90 per month, that first quarterly bill totals $608.70. Many people do not budget for this lump sum, which can create financial stress right at the start of Medicare enrollment.
If you also owe a Part D IRMAA surcharge or Part A premium, those amounts appear as separate line items on the same first bill. The total can climb even higher depending on your income level and coverage.
How Premiums Are Deducted From Social Security
Most Medicare beneficiaries never see a premium bill because their Part B premium is automatically deducted from their Social Security benefit payment each month. The same applies if you receive Railroad Retirement Board (RRB) benefits. This is the most common way Part B premiums are collected.
The deduction happens before your Social Security payment reaches your bank account. Because Social Security pays in arrears (your August check covers July benefits) and Medicare charges in advance, the Part B deduction from your August check pays for September coverage. You never have to write a check or log in to make a payment.
This setup means your net Social Security deposit is always lower than your gross benefit amount. For example, if your monthly Social Security benefit is $1,800 and your Part B premium is $202.90, your actual deposit is $1,597.10. Many beneficiaries see this smaller number and wonder where the rest went.
What If You Are Not Receiving Social Security Yet?
If you have enrolled in Medicare Part B but have not yet started collecting Social Security retirement benefits, Medicare sends you a premium bill directly. This is common for people who turn 65 but choose to delay Social Security to increase their monthly benefit.
You must choose one of four payment methods to pay your bill. Missing a payment because you expected an automatic deduction is a common and costly mistake. You are personally responsible for tracking due dates and submitting payments on time.
People in this situation often delay Social Security until age 67 or even 70 to maximize their retirement benefit. During those years, they must remember to pay Part B premiums on their own every quarter.
What If You Get Retroactive Social Security Payments?
Some beneficiaries receive a lump-sum retroactive Social Security payment when they first start benefits. In these cases, Medicare deductions typically start on the first check you receive, including any premium arrears that may have accumulated. If you overpaid premiums during the period before Social Security started, you may receive a refund.
The transition from direct billing to automatic Social Security deduction is not always smooth. There can be a lag of one to two billing cycles where you might receive both a bill and a deduction. Keep records of all payments during this transition period to avoid double-paying.
Four Ways to Pay Your Part B Premium Bill
Medicare gives you four payment options if you are billed directly. Each has its own processing time, and choosing the wrong one could put your payment at risk of arriving late.
Pay Online Through Your Medicare Account
You can log into your account at Medicare.gov and select “Pay My Premium Now.” You can use a credit card, debit card, or pay directly from a checking or savings account. Credit card payments process faster, while bank account payments take about 5 business days. You receive a confirmation number as proof of payment.
This method gives you immediate confirmation that your payment was submitted. Keep your confirmation number in a safe place in case there is a dispute about whether you paid on time.
Medicare Easy Pay (Automatic Bank Draft)
Medicare Easy Pay is an automatic payment option that drafts your premium from your bank account on the 20th of each month (or the next business day). It can take 6 to 8 weeks to set up, so you must continue paying your premiums another way until it starts.
This is the preferred method for people who are not yet receiving Social Security. It removes the risk of forgetting a payment. Once Social Security benefits begin, the automatic deduction from your benefit check replaces Medicare Easy Pay.
You can sign up for Medicare Easy Pay through your online Medicare account or by completing a paper enrollment form. If Medicare cannot set up Easy Pay for your account, they will mail you a letter explaining why.
Pay Through Your Bank’s Online Bill Pay
You can add CMS Medicare Insurance as a payee through your bank’s online bill payment service. Use your Medicare Number as the account number. Some banks charge a service fee for this option, so check with your bank first.
This method works well if you already manage other bills through your bank’s website. Processing times vary by bank, so allow extra days compared to paying directly through Medicare’s site.
Pay by Mail
You can mail a check, money order, credit card payment, debit card payment, or HSA card payment to the Medicare Premium Collection Center. You must include the payment coupon from the bottom of your bill. If you pay by credit or debit card, you must also sign the coupon, or Medicare will return your payment unprocessed.
Mail your payment to:
Medicare Premium Collection Center
PO Box 790355
St. Louis, MO 63179-0355
Mailing takes the longest to process. Submit your payment at least 5 business days before the due date to avoid a late payment. If you do not have your payment coupon, write your Medicare Number on the check or money order so Medicare can apply it to your account.
| Payment Method | Processing Time |
|---|---|
| Online via Medicare account | Credit card: fast; bank: ~5 days |
| Medicare Easy Pay | Auto-drafted on the 20th |
| Bank online bill pay | Varies by bank |
| Mail (check/card) | Longest processing time |
The 2026 Part B Premium and IRMAA Surcharges
The standard Part B premium for 2026 is $202.90 per month, a $17.90 increase from 2025. CMS noted that without action by the Trump Administration to reduce spending on skin substitutes, the premium increase would have been about $11 more per month.
The annual Part B deductible for 2026 is $283, up from $257 in 2025. You must pay this deductible before Medicare begins covering 80% of your outpatient services. The premium and deductible are two separate costs — paying your monthly premium does not count toward your deductible.
What Is IRMAA and How Does It Inflate Your Premium?
IRMAA stands for Income-Related Monthly Adjustment Amount. It is an extra charge added to your Part B premium if your modified adjusted gross income (MAGI) from two years ago exceeds certain thresholds. About 8% of Medicare Part B enrollees pay IRMAA.
Your 2026 IRMAA is based on your 2024 tax return. CMS uses a two-year lookback because those are the most recent tax records available from the IRS when premiums are calculated. This means a spike in income in 2024 — from selling a home, converting a traditional IRA to a Roth, or receiving a large bonus — could trigger a surcharge in 2026.
IRMAA is not a separate bill. It is added to your standard premium, so you see one combined amount deducted from Social Security or billed to you each month. The surcharge disappears if your income drops below the threshold in a future year.
2026 IRMAA Brackets for Part B (Single Filers)
| 2024 MAGI (Single Filer) | Total Monthly Part B Premium |
|---|---|
| $109,000 or less | $202.90 |
| $109,001 – $137,000 | $284.10 |
| $137,001 – $171,000 | $405.50 |
| $171,001 – $205,000 | $526.90 |
| $205,001 – $499,999 | $648.30 |
| $500,000 or more | $689.90 |
2026 IRMAA Brackets for Part B (Married Filing Jointly)
| 2024 MAGI (Joint Filers) | Total Monthly Part B Premium |
|---|---|
| $218,000 or less | $202.90 |
| $218,001 – $274,000 | $284.10 |
| $274,001 – $342,000 | $405.50 |
| $342,001 – $410,000 | $526.90 |
| $410,001 – $749,999 | $648.30 |
| $750,000 or more | $689.90 |
The highest Part B premium in 2026 is $689.90 per month, which totals $8,278.80 per year. The top income bracket remains frozen through 2028, meaning it will not adjust for inflation during that period. Beneficiaries in the highest bracket pay more than three times the standard premium.
How to Appeal an IRMAA Decision
If your income dropped because of a life-changing event — such as retirement, divorce, death of a spouse, or loss of income-producing property — you can request a new initial determination from Social Security. You file this appeal using Form SSA-44, and Social Security may use a more recent tax year to recalculate your premium.
Qualifying life-changing events include marriage, divorce, death of a spouse, work stoppage, work reduction, loss of income-producing property, loss of pension income, and receipt of a settlement from an employer or former employer. You should gather supporting documents — such as a letter from your former employer, a divorce decree, or a death certificate — before filing the appeal.
The appeal process can take several weeks. During that time, you must continue paying the higher IRMAA amount. If your appeal is approved, Social Security will adjust your premium going forward and may refund overpayments.
The Part B Late Enrollment Penalty: A Permanent Price Increase
If you do not sign up for Part B when you are first eligible and you do not have qualifying coverage through an employer, Medicare charges a late enrollment penalty (LEP). This penalty is not a one-time fee. It is a permanent increase added to your monthly premium for as long as you have Part B.
The Initial Enrollment Period (IEP) begins three months before your 65th birthday and ends three months after, giving you a seven-month window to sign up. Missing this window without creditable coverage triggers the penalty.
How the Penalty Is Calculated
The penalty equals 10% of the standard premium for each full 12-month period you could have had Part B but did not enroll. The standard premium for 2026 is $202.90, so each year of delay adds roughly $20.29 per month to your bill.
The penalty percentage is locked in, but the dollar amount changes each year because it is recalculated against the current standard premium. If the standard premium rises to $220 in 2027, a 20% penalty would become $44 per month instead of $40.58.
| Years Without Part B | Total Monthly Premium (2026) |
|---|---|
| 1 year (10% penalty) | $223.19 |
| 2 years (20% penalty) | $243.48 |
| 3 years (30% penalty) | $263.77 |
| 5 years (50% penalty) | $304.35 |
Example: How a 2-Year Delay Costs Thousands
Meet Linda, age 67. She retired at 65 but forgot to sign up for Part B because she thought her COBRA coverage was sufficient. COBRA is not considered creditable employer coverage for Medicare purposes. Linda waited 2 full years before enrolling.
Linda now pays a 20% penalty on top of her standard premium. In 2026, that means she pays $243.48 per month instead of $202.90. Over 10 years, Linda will pay approximately $4,869.60 more than she would have if she had enrolled on time. This penalty never goes away.
If Linda also has IRMAA because of higher income, the penalty is added to the standard premium first, and then the IRMAA surcharge is applied on top. The combined cost can be staggering for high-income beneficiaries who also delayed enrollment.
When the Penalty Does Not Apply
You can avoid the late enrollment penalty if you had creditable coverage through an employer or union during the time you were eligible but not enrolled. When that employment or coverage ends, you qualify for a Special Enrollment Period (SEP) to sign up without a penalty.
The SEP lasts 8 months starting the month after your employment ends or your employer coverage ends, whichever comes first. You do not need to wait for the General Enrollment Period if you qualify for a SEP.
The General Enrollment Period runs from January 1 through March 31 each year, with coverage beginning on July 1. If you missed your initial enrollment and did not have creditable coverage, you must wait for this window and will face the late enrollment penalty.
What Happens When You Do Not Pay Your Part B Premium
Failing to pay your Part B premium sets off a formal termination process with specific deadlines and consequences. Understanding this process gives you time to fix the problem before you lose coverage.
The 90-Day Grace Period
Under federal rules, Medicare provides a 90-day grace period for unpaid premiums before termination occurs. The clock starts differently depending on whether you pay directly or have premiums deducted from Social Security, but the grace period length is the same. This rule was established to create a uniform timeframe for all Part B enrollees regardless of how they pay.
During this period, Medicare sends three notices:
- Second Notice — A warning that your account is delinquent
- Delinquent Notice — Sent about one month before the grace period ends, specifying the exact termination date
- Termination Letter — Sent roughly 30 days after the grace period expires, confirming your coverage has ended
If your payment is received within 30 days after termination, your coverage may be reinstated. You can also pay the full amount owed at any time during the four-month process to stop the termination.
Each notice arrives about 30 days apart. The entire process — from first missed payment to final termination — spans roughly four months. Do not ignore any of these notices.
The Consequences of Losing Part B Coverage
Losing Part B coverage is serious. You cannot simply re-enroll whenever you want. You must wait until the next General Enrollment Period (January 1 – March 31), and coverage will not start until July 1 of that year. During the gap, you have no outpatient Medicare coverage.
You will also face the late enrollment penalty when you re-enroll. Every full 12-month period without Part B adds 10% to your premium permanently. A coverage gap caused by nonpayment can create a financial burden that lasts the rest of your life.
Doctor visits, lab tests, imaging, outpatient surgeries, and preventive care all go uncovered during the gap. If you have a medical emergency requiring outpatient treatment, you pay 100% out of pocket.
| Timeline Event | What Happens |
|---|---|
| First missed payment | Bill arrives; premium is past due |
| ~30 days later | Second Notice: delinquency warning |
| ~60 days later | Delinquent Notice: termination date given |
| 90 days (grace period ends) | Coverage terminated |
| Within 30 days of termination | Possible reinstatement if paid in full |
| After 30-day reinstatement window | Must wait for General Enrollment Period |
Three Real-World Scenarios: How Advance Billing Plays Out
Scenario 1: New Enrollee Not Receiving Social Security
Tom turns 65 in March 2026 and enrolls in Part B during his Initial Enrollment Period. He has not started collecting Social Security benefits yet. His Part B coverage begins April 1, 2026.
| What Happens | When It Happens |
|---|---|
| Tom receives his first bill (covers April, May, June) | March 2026 |
| Amount due: $202.90 × 3 = $608.70 | Due by March 25, 2026 |
| Tom’s next bill arrives (covers July, Aug, Sept) | June 2026 |
| Amount due: $608.70 | Due by June 25, 2026 |
Tom’s first payment is due before his coverage even starts. He pays three months of premiums up front. If Tom does not budget for that $608.70 lump sum, he risks starting Medicare with a past-due balance.
Tom decides to sign up for Medicare Easy Pay to avoid managing quarterly bills. He submits the enrollment form in March, but Easy Pay takes 6–8 weeks to activate. Tom must pay his first quarterly bill manually while waiting for the automatic drafts to begin.
Scenario 2: Already Receiving Social Security
Maria turned 65 in January 2026 and was already receiving Social Security retirement benefits. She was automatically enrolled in Part B. Her Part B premium is deducted from her monthly Social Security check.
| What Happens | When It Happens |
|---|---|
| Maria’s January Social Security check (for December benefits) | January 2026 |
| Part B deduction from January check covers February coverage | January 2026 |
| Maria’s February check (for January benefits) | February 2026 |
| Part B deduction from February check covers March coverage | February 2026 |
Maria never sees a bill. The advance payment structure is invisible to her because Social Security handles everything. The only time she notices the premium is when she reviews her Social Security statement and sees the deduction.
Maria’s monthly Social Security benefit is $2,100. After the $202.90 Part B deduction, she receives $1,897.10 in her bank account. She does not need to take any action to keep her Part B coverage active.
Scenario 3: Switching From Employer Coverage to Medicare
James is 68 and worked at a large company with employer health insurance. He delayed Part B enrollment because he had creditable employer coverage. James retires in September 2026 and enrolls in Part B through a Special Enrollment Period.
| What Happens | When It Happens |
|---|---|
| James retires and employer coverage ends | September 30, 2026 |
| James enrolls in Part B; coverage starts October 1 | October 2026 |
| First bill arrives (covers Oct, Nov, Dec) | September 2026 |
| Amount due: $202.90 × 3 = $608.70 | Due by September 25, 2026 |
| No late enrollment penalty applies | James had creditable coverage |
James avoids the late enrollment penalty because he had qualifying employer coverage. His first bill still requires three months of premiums up front, paid in advance of his October coverage start date.
James had the foresight to request a Certificate of Creditable Coverage from his employer’s HR department before retiring. This document proves he had qualifying coverage and protects him from a penalty dispute down the road.
Are Medicare Part B Premiums Tax-Deductible?
Yes, your Part B premiums qualify as a tax deduction, but how you deduct them depends on your employment status. The rules differ for retirees, employed individuals, and self-employed beneficiaries.
For Most Beneficiaries: Itemized Deduction
Medicare Part B premiums count as a medical expense on Schedule A (Form 1040) if you itemize deductions. Your total medical expenses must exceed 7.5% of your adjusted gross income (AGI) before you can deduct the amount above that threshold. For many retirees, the standard deduction is higher than their itemized deductions, making this path less useful.
At $202.90 per month in 2026, your annual Part B premiums total $2,434.80. If your AGI is $50,000, your medical expense threshold is $3,750. You would need more than $3,750 in total medical expenses before any deduction kicks in.
Qualifying medical expenses include Part B premiums, Part D premiums, Medigap premiums, dental bills, vision care, hearing aids, and out-of-pocket prescription costs. Adding these together may push you past the 7.5% threshold, especially if you had a year with significant medical bills.
For Self-Employed Individuals: Above-the-Line Deduction
Self-employed individuals get a much better deal. You can deduct 100% of your Medicare premiums — including Parts A, B, C, D, and Medigap — as an above-the-line deduction on Schedule 1 (Form 1040). This reduces your AGI directly, which can lower your overall tax bill and potentially reduce your IRMAA surcharge in future years.
A 67-year-old sole proprietor with $40,000 in net profit and $2,500 in annual Medicare premiums can deduct the full $2,500 on Schedule 1. The catch: you must have net self-employment income, and you cannot have access to an employer-subsidized health plan. If your business shows a net loss, you cannot claim this deduction, though you may still deduct the premiums as itemized medical expenses.
The IRS has confirmed that self-employed Medicare recipients can deduct premiums the same way they would any other health insurance premium. This applies whether the premium is paid directly or withheld from Social Security benefits.
| Deduction Type | Who Qualifies |
|---|---|
| Medical expense (itemized, Schedule A) | All taxpayers who itemize and exceed 7.5% AGI |
| Self-employed health insurance (Schedule 1) | Self-employed with net income, no employer plan available |
Mistakes to Avoid With Medicare Part B Premiums
Mistake 1: Assuming COBRA Counts as Creditable Coverage
COBRA allows you to continue employer coverage temporarily after leaving a job. Many people assume this counts as creditable coverage that lets them delay Part B enrollment. It does not. If you rely on COBRA and skip Part B, you will face the late enrollment penalty when you eventually enroll. The penalty is permanent and increases each year you were eligible but not enrolled.
COBRA coverage typically lasts 18 months after you leave your job. If you wait until COBRA ends to enroll in Part B, you may have accumulated a penalty of 10% or more, depending on how long you were eligible for Medicare before COBRA started.
Mistake 2: Forgetting to Set Up Payments Before Social Security Starts
If you enroll in Part B before starting Social Security benefits, you are responsible for paying the premium directly. Many beneficiaries assume premiums will be automatically handled. They are not. You must actively choose one of the four payment methods and make payments on time, or risk delinquency and termination.
Set up Medicare Easy Pay as soon as you receive your first bill. Even if it takes weeks to activate, it ensures you will not miss payments going forward.
Mistake 3: Not Budgeting for the First Quarterly Bill
Your first Part B bill covers three months and is due before coverage starts. At the 2026 rate, that is $608.70 due all at once. People who expect a single monthly bill of $202.90 are caught off guard by the larger first payment.
Plan ahead by setting aside three months of premiums before your Part B start date. Mark the due date on your calendar and pay early to avoid processing delays.
Mistake 4: Ignoring IRMAA Because You Think It Does Not Apply
IRMAA is based on your income from two years ago. A one-time income spike in 2024 — such as selling a rental property or taking a large 401(k) distribution — can push you into a higher IRMAA bracket in 2026. Many people do not connect a past financial event to a future Medicare premium increase.
Work with a financial advisor or tax professional to plan large income events before they happen. Spreading a Roth conversion over two years instead of one could keep you below the IRMAA threshold.
Mistake 5: Missing the Payment Due Date by Mailing Late
Medicare bills are due on the 25th. Mail payments take the longest to process. If you mail a check on the 22nd, it likely will not arrive by the 25th. Repeated late payments can trigger the delinquency process. Use online payment or Medicare Easy Pay to avoid this risk entirely.
Pros and Cons of Medicare Part B’s Advance Payment Structure
| Pros | Cons |
|---|---|
| Ensures coverage is funded before you need care | First quarterly bill can be a financial shock ($608.70 in 2026) |
| Automatic Social Security deduction is effortless | Creates confusion about which month the premium covers |
| Medicare Easy Pay offers set-it-and-forget-it convenience | 6–8 week setup time for Medicare Easy Pay leaves a gap |
| Multiple payment methods available (online, mail, bank) | Mail payments risk arriving late and triggering delinquency |
| Premium payments may be tax-deductible | Tax deduction limited by 7.5% AGI threshold for most people |
| Predictable billing cycle every 3 months for direct payers | Quarterly lump sums harder to budget than monthly payments |
Do’s and Don’ts for Managing Part B Premiums
Do’s
- Do sign up for Medicare Easy Pay if you are not receiving Social Security benefits. It automatically drafts your premium and eliminates the risk of missed payments.
- Do budget for a three-month first bill when enrolling in Part B for the first time. Set aside at least $608.70 (at 2026 rates) before your coverage start date.
- Do file Form SSA-44 if your income dropped due to a life-changing event. You may qualify for a lower IRMAA surcharge based on more recent income.
- Do check your Social Security statement regularly to confirm the correct Part B premium is being deducted, especially after IRMAA changes.
- Do submit mail payments at least 5 business days early to ensure Medicare receives your payment by the 25th due date.
- Do keep records of all premium payments during the transition from direct billing to Social Security deduction.
Don’ts
- Don’t assume COBRA is creditable coverage for Medicare purposes. It is not, and relying on it will result in a permanent late enrollment penalty.
- Don’t ignore a “Delinquent Bill” notice. This is your final warning before termination. Pay the total amount due immediately to keep your coverage.
- Don’t forget that IRMAA uses a two-year lookback. A large income event in 2024 affects your 2026 premiums. Plan major financial moves with Medicare costs in mind.
- Don’t wait until the last day to pay by mail. Processing delays could cause your payment to arrive late, putting your coverage at risk.
- Don’t skip Part B enrollment assuming you will enroll later. Every 12 months you delay without creditable coverage adds a 10% permanent penalty to your premium.
- Don’t forget to request a Certificate of Creditable Coverage from your employer if you delayed Part B enrollment. This document protects you from penalty disputes.
Key Entities That Manage Your Part B Premiums
Centers for Medicare & Medicaid Services (CMS) is the federal agency that administers Medicare. CMS sets the annual Part B premium and deductible based on projected healthcare costs and utilization. CMS also manages the Medicare Premium Collection Center in St. Louis, Missouri, where mailed payments are processed.
Social Security Administration (SSA) handles the deduction of Part B premiums from Social Security benefit checks. SSA also determines IRMAA based on income data it receives from the IRS. If you need to appeal an IRMAA decision, you file Form SSA-44 with the SSA.
The Railroad Retirement Board (RRB) serves the same function as SSA for railroad workers and their families. If you receive RRB benefits, your Part B premium is deducted from your RRB payment. Payment methods differ for RRB beneficiaries — Medicare Easy Pay and online payment are not available. You must mail premium payments to the RRB.
The Internal Revenue Service (IRS) provides the income data that SSA uses to calculate IRMAA. Your modified adjusted gross income from your tax return two years prior determines whether you pay the standard premium or a higher amount. The IRS also governs the tax deductibility of Part B premiums for both itemizers and self-employed individuals.
Medicare Part B Premium: Advance Payment FAQs
Are Medicare Part B premiums paid in advance or arrears?
Yes, they are paid in advance. Your premium payment each month covers the next month’s Part B coverage, not the current month.
How much is the standard Part B premium in 2026?
The standard monthly premium is $202.90. Higher-income beneficiaries pay more due to IRMAA surcharges based on their 2024 tax returns.
Can I pay my Part B premium with a credit card?
Yes, you can pay by credit card online through your Medicare account or by including card information on the payment coupon mailed to Medicare.
What happens if I miss a Part B premium payment?
You enter a 90-day grace period. If you do not pay within that window, Medicare terminates your Part B coverage and sends a delinquency notice.
Is the Part B late enrollment penalty permanent?
Yes, the penalty lasts as long as you have Part B. It adds 10% per year of delay to your standard monthly premium amount.
Can I deduct Part B premiums on my taxes?
Yes, if you itemize deductions and total medical expenses exceed 7.5% of AGI. Self-employed individuals can deduct premiums above the line.
Does COBRA count as creditable coverage for Medicare?
No, COBRA does not qualify as creditable employer coverage. Delaying Part B while on COBRA will trigger the permanent late enrollment penalty.
What is IRMAA for Medicare Part B?
IRMAA is an income-based surcharge on your Part B premium. It applies if your 2024 MAGI exceeds $109,000 (single) or $218,000 (joint filers).
Can I appeal my IRMAA surcharge?
Yes, file Form SSA-44 with Social Security if you experienced a life-changing event that reduced your income below the IRMAA threshold amount.
