Why Some Retirees Pay Nearly $700 a Month for Medicare While Others Pay Almost $500 Less

Two retirees can sit together in a waiting room with identical Medicare coverage and very different monthly bills. One might pay the standard Part B premium of $202.90, while the other pays as much as $689.90.

The difference usually doesn't come from health, plan choice, or how often they see a doctor. Instead, an income‑based surcharge called IRMAA quietly raises costs for people whose past income crosses specific thresholds. Without planning ahead, these excesses can add thousands of dollars to your annual retirement budget.

When you understand how IRMAA works, you can avoid wasting money in retirement and make smarter Medicare decisions.

What are IRMAA surcharges?

IRMAA stands for Income-Related Monthly Adjustment Amount, which is a premium increase added to Parts B and D of Medicare. When your modified adjusted gross income increases beyond certain amounts, you pay more for the same basic coverage by Medicare. You do not pay IRMAA as an independent bill, since Social Security simply raises the amount of premiums deducted out of your benefits.

In 2026, IRMAA will be allowed to increase the standard premiums of Part B (the standard is currently $202.90) to as much as $689.90 per month. Part D IRMAA increases your prescription payments by between $14.50 and $91 each month, based on your income.

What triggers higher premiums?

IRMAA kicks in when your modified adjusted gross income from two years earlier crosses specific IRS‑reported thresholds. For 2026, you pay IRMAA if your 2024 income exceeded $109,000 as a single filer, or $218,000 as a married couple filing jointly. Medicare uses several brackets, so a higher income will lead to higher surcharges at each step.

Even small changes matter, as one analysis shows a $5,000 increase can add $974 in yearly premiums. That result occurs when income jumps from $215,000 to $220,000, crossing into a higher Part B IRMAA tier. You feel these costs later, because a big IRA withdrawal or home sale today shows up in premiums two years from now.

How to reduce these costs

You can't exactly haggle IRMAA away, but you can manage income so you cross fewer of those costly thresholds. Let's explore some of the clever moves that you can now make to keep your Medicare costs low.

Plan IRA and 401(k) withdrawals carefully

Massive withdrawals of traditional IRAs or 401(k)s tend to thrust retirees into higher IRMAA payments unintentionally. Rather than making a single distribution, you make the withdrawals in different tax years to even out your income. You then add in small amounts of necessary required minimum with Roth or taxable savings, which helps you stay just under key thresholds.

Time big financial moves before Medicare

Big events like selling a business, a second home, or highly appreciated investments can create one‑time income spikes. When you can, complete these transactions at least two years before you enroll in Medicare. If that's not realistic for your financial situation, work with a tax professional to spread gains over several years instead.

Consider Roth strategies earlier in retirement

Roth conversions and contributions before Medicare age reduce future taxable income that counts toward IRMAA calculations. By shifting money from traditional accounts to Roth accounts earlier, you shrink later required minimum distributions (RMDs). You pay taxes on conversions now, but you potentially trade that bill for many years of lower Medicare premiums.

Use IRMAA appeals when your income truly falls

If your income drops after a major life change, you don't always have to stay stuck with high surcharges. Social Security lets you appeal IRMAA when retirement, divorce, or a spouse's death significantly reduces your income. If this is your situation, you can file Form SSA‑44 and ask them to base premiums on current income, which can lower future charges.

Coordinate Social Security and pension income

You can sometimes choose when to start Social Security or a pension, which affects how much taxable income appears each year. Delaying one income source while drawing from savings can keep your total income under key IRMAA thresholds. Later, when you turn on those benefits, plan withdrawals more conservatively so your combined income stays smoother.

Use tax‑efficient investing and withdrawals in taxable accounts

How you invest outside retirement accounts also influences income that counts toward IRMAA, especially interest, dividends, and capital gains. Favoring more tax‑efficient funds, like broad index funds or exchange-traded funds (ETFs), could reduce surprise taxable distributions. You can sell investments to generate gains over several years so that, when you need money, you don't trigger a single taxable incident.

Bottom line

IRMAA is the reason some retirees pay $284, $402, or even $689 a month while neighbors pay $202.90. Because Medicare looks at income from two years ago, a decision you make today can raise premiums later. One detail many retirees overlook is how future inflation adjustments can nudge income higher while brackets move more slowly.

That pattern exposes more middle‑class households to surcharges, even when their lifestyle doesn't feel "high income." Now is a good time to check up on your retirement readiness and see how your retirement savings stack up. When you plan withdrawals, big financial moves, Roth strategies, and appeals carefully, you keep more of your Medicare costs firmly under control.
