Medicare Part B IRMAA in 2026: What Higher-Income NC Retirees Should Know

MedicareUpdated May 2026

North Carolina retirees reviewing Medicare Part B IRMAA information and financial documents

Quick answer: Medicare Part B IRMAA is an extra premium for higher-income beneficiaries, calculated based on modified adjusted gross income from two years prior. North Carolina retirees can plan by reviewing their income, appealing if eligible, and consulting local insurance experts.

What is Medicare Part B IRMAA?

The Income-Related Monthly Adjustment Amount (IRMAA) is an additional charge added to the standard Medicare Part B premium for beneficiaries with higher incomes. It helps fund Medicare by requiring those with greater financial means to contribute more toward their healthcare coverage.

How is IRMAA Calculated for 2026?

IRMAA is determined based on your modified adjusted gross income (MAGI) from two years prior, as reported on your federal tax return. For 2026 premiums, the Social Security Administration (SSA) uses your 2024 tax data to calculate whether you owe an IRMAA surcharge.

The MAGI thresholds and corresponding IRMAA amounts are adjusted annually. If your income exceeds certain limits, you will pay an increased monthly premium on top of the standard Medicare Part B premium.

Income Brackets and Premiums

Medicare sets several income brackets. For example, individuals with MAGI above a specific threshold will pay a higher IRMAA amount. These brackets apply to individuals and married couples filing jointly, with surcharges increasing as income rises.

Who Pays Medicare Part B IRMAA?

Only Medicare beneficiaries whose income exceeds the established thresholds pay IRMAA. This generally includes retirees with significant earnings from pensions, investments, or other sources. Those with income below the thresholds pay the standard Part B premium without IRMAA.

It is important for retirees to understand that IRMAA is assessed individually, so even if a spouse’s income is lower, the higher-earning spouse’s income determines the IRMAA surcharge for both if filing jointly.

What North Carolina Retirees Can Do to Plan for IRMAA

North Carolina retirees can take several steps to prepare for Medicare Part B IRMAA in 2026:

Review Your Income: Understand your MAGI from 2024 and how it impacts your 2026 premiums. Consider how investment income, retirement account withdrawals, and other earnings affect your total income.
Consider Income Strategies: Work with a financial advisor or insurance expert to explore ways to manage income, such as timing withdrawals or utilizing tax-advantaged accounts, to potentially reduce your MAGI.
Appeal IRMAA if Applicable: If your income has decreased due to life-changing events like retirement, divorce, or loss of income, you can file an appeal with SSA to adjust your IRMAA.
Consult Local Experts: North Carolina retirees can benefit from personalized insurance planning advice. Agencies like Foxworth Insurance Agency offer guidance tailored to your situation.

Putting It in Perspective for North Carolina Households

Every North Carolina household weighs insurance decisions a little differently. A retiree in Mooresville may have very different priorities from a young family in Charlotte or a self-employed worker in Greensboro. The themes in this article apply broadly, but the right choice always depends on personal health needs, family obligations, and budget. For that reason, we walk every client through the specifics of their situation rather than relying on rules of thumb. The goal is a coverage plan you understand and can defend on paper, not a stack of policies that looks impressive but never gets reviewed.

Reviewing this kind of decision once a year is a healthy habit. Carriers update their plans annually, networks shift, prescription formularies are revised, and personal circumstances change too. If you take nothing else from this article, take that: schedule a yearly review of your existing coverage, even when nothing obvious has changed. Small misalignments compound over time, and catching them in a calm year is far easier than reacting to a surprise.

Key questions to ask yourself before you act

What is the specific problem this coverage needs to solve for my household?
What is the worst case I'm protecting against, and how likely is it?
Are my doctors, pharmacy, and preferred hospital in the plans I'm considering?
Has anything changed in my household in the last year — income, dependents, health status, or where I live?
Do I understand exactly when this plan can be changed and what triggers an exception?

These questions don't replace a conversation with a licensed agent, but they help organize your thinking. They are also the same questions we use as the starting point for a Foxworth Insurance Agency review, so coming in prepared shortens the meeting and lets us focus on the parts of medicare part b irmaa 2026 that matter most to you.

Common Pitfalls We See in Medicare

Across the medicare conversations we have with North Carolina clients, a handful of avoidable mistakes show up again and again. The first is treating a renewal letter as junk mail. Annual notices from carriers contain the changes that will affect your wallet next year — premium adjustments, formulary changes, or new prior-authorization rules — and they're easy to skim past. Read it slowly, mark the date you received it, and compare line by line to last year's letter.

The second is assuming that the cheapest premium is the cheapest plan. The premium is only one part of the total cost equation. Deductibles, copays, coinsurance, out-of-pocket maximums, and which prescriptions sit on which tier can all change the picture dramatically. A plan that costs a little more per month may save several hundred dollars over a year if it lines up better with how you actually use care.

The third is making changes outside an enrollment window without confirming that a qualifying event applies. Most coverage in this category can only be changed during specific periods. Acting on a hunch — or on advice from a well-meaning relative who lives in another state — can lock in a plan that doesn't fit, with no easy way to undo it. Confirming the rule before you act is always cheaper than discovering it after.

How a Licensed Agent Adds Value

A licensed insurance agent is not just a salesperson — at their best, they're an educator and a long-term resource. The value shows up in three places. First, in product knowledge: a good agent reads the fine print so you don't have to, and can translate dense policy language into plain English. Second, in side-by-side comparison: comparing several carriers' plans against each other is tedious without help, and licensed agents have the tools to do it cleanly. Third, in follow-up: when something changes mid-year — a new prescription, a move across counties, or a life event — your agent is the first call you can make.

At Foxworth Insurance Agency, we work with multiple carriers, which means we can compare options without being limited to a single company's lineup. Our role is to help you understand the choices, not to push a specific product. When we recommend a plan, we explain why, and we'll show you what we considered and ruled out so you can sense-check the logic.

What to bring to a coverage review

A list of all current medications and their dosages
Names and locations of your primary care doctor and any specialists
Your preferred pharmacy and preferred hospital
Last year's premium, deductible, and out-of-pocket totals if you have them
Any annual notices or letters from your current carrier
A short summary of any health, family, or income changes in the last twelve months

You don't need to have all of this perfectly organized — we can help you reconstruct it during the meeting if needed. The list above is simply what makes a review most efficient.

What Comes Next

If you read this far, you're already doing the hardest part: taking time to understand the moving pieces before they affect you. The next step depends on where you are in the calendar. If an enrollment window is open, the priority is comparing your current plan against the alternatives and acting before the deadline. If you're between windows, the priority is documenting what you have today so you're ready when the next window opens. Either way, a short conversation with a licensed agent can confirm whether your current setup is still the right fit or whether a change is warranted.

For North Carolina families who would like a second set of eyes on their medicare situation, Foxworth Insurance Agency offers no-pressure reviews. We'll listen to your goals, walk through what you have today, and explain options in plain language. Reach out anytime — there's no obligation, and we'd rather you leave the conversation informed than feel pushed into a decision.
