Social Security Benefits Rise 2.8% but Medicare Eats the Gain

The Phone Call That Changed Margaret’s Retirement Math

Margaret called my office on a Tuesday morning in late May, and I could hear the frustration in her voice before she even finished her first sentence. “Robert, I just got my Social Security statement for 2026. They’re giving me a raise — $53 more per month. But my Medicare premium went up again, and now my Medigap plan costs more too. I’m actually bringing home less than I did last year.”

Margaret is 71, a retired school librarian in suburban Ohio, and she’s far from alone. In my 20 years as a CPA and Enrolled Agent working primarily with retirees, I’ve watched this pattern repeat almost every single year — but 2026 feels like it’s hitting harder than most. The Social Security Administration announced a 2.8% cost-of-living adjustment (COLA) for 2026, which sounds like welcome news until you look at what’s happening on the other side of the ledger.

What I see most often is retirees doing exactly what Margaret did: they read the headline, see a percentage increase, and feel a brief moment of relief. Then the reality of rising healthcare premiums, supplemental insurance costs, and persistent grocery inflation chips away at that number until the “raise” effectively vanishes — or worse, turns negative.

This article isn’t about panic. It’s about arithmetic, strategy, and making sure you keep more of what you’ve earned.

What the 2.8% COLA Actually Means in Dollar Terms

Let’s start with the raw numbers. According to the Social Security Administration, the average retired worker’s monthly benefit in 2025 was approximately $1,976. A 2.8% COLA bumps that to roughly $2,031 — an increase of about $55 per month, or $660 per year.

For couples where both spouses collect benefits, the combined annual increase might land somewhere around $1,100 to $1,300. On paper, that’s meaningful. In practice, it depends entirely on what else changes in your monthly expenses.

“A COLA is designed to help you keep up with inflation — not get ahead of it. When healthcare costs rise faster than the general consumer price index, retirees on fixed incomes are the first to feel the squeeze.”

The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which many economists and advocacy groups have long argued doesn’t accurately reflect the spending patterns of older Americans. Seniors typically spend a far larger share of their income on healthcare and housing — two categories where inflation has consistently outpaced the general index.

Medicare’s Growing Bite: The Real Story of 2026

Here’s where Margaret’s frustration comes into sharp focus. The standard Medicare Part B premium for 2026 is projected to rise to approximately $185 per month, up from $185 in 2025 — but that baseline number masks a much bigger story for many retirees. If you’re subject to IRMAA (Income-Related Monthly Adjustment Amount), your premiums could be significantly higher, and the income thresholds that trigger those surcharges have shifted in ways that catch people off guard.

I often tell my clients to think about their Medicare costs as a three-layer cake:

• Part B premiums — covering doctor visits and outpatient care, deducted directly from your Social Security check
• Part D premiums — prescription drug coverage, also subject to IRMAA surcharges for higher earners
• Supplemental coverage — Medigap or Medicare Advantage plan premiums, which are set by private insurers and have been climbing steadily

When you stack all three layers, many retirees find that their total healthcare premium burden in 2026 eats up not just their COLA increase but a chunk of their existing benefit too. For a deeper look at how IRMAA surcharges specifically affect retirees, I’d recommend reading The $487 Medicare Surprise: How IRMAA Hits Your Retirement.

Medicare Advantage Enrollment Shifts Are Adding Complexity

Over 33 million Americans are now enrolled in Medicare Advantage plans, and the 2026 enrollment cycle has introduced some notable changes. Several major insurers have reduced benefits, narrowed provider networks, or increased out-of-pocket maximums in specific markets. If you’re enrolled in a Medicare Advantage plan, it’s critical to review your Annual Notice of Change — that document your plan sent in October — because what worked for you in 2025 may not work in 2026.

I’ve seen clients lose access to preferred specialists, face higher copays for prescription drugs, or discover that their plan no longer covers certain imaging services — all without changing a single thing on their end. The plan changed around them.

The Inflation Squeeze Beyond Healthcare

Healthcare is the most visible expense eating into that 2.8% COLA, but it’s not the only one. A recent survey by the Employee Benefit Research Institute found that nearly 40% of retirees reported depleting their savings faster than expected, with inflation in food, utilities, and home maintenance cited as primary drivers.

Margaret told me her grocery bill is up roughly 18% compared to three years ago. Her homeowners insurance premium jumped 12% in one year — a trend I’m seeing across the board, especially for clients in the South and Midwest. Her property taxes increased by 6%. None of these expenses are optional.

“The danger isn’t a single large expense wiping out your retirement. It’s the slow, steady erosion of purchasing power — death by a thousand small price increases that individually seem manageable but collectively change everything.”

If this pattern sounds familiar, you’re not imagining things. I wrote a detailed data analysis on this exact trend in Inflation vs. Retirement Savings: A CPA’s 2026 Data Analysis, and the numbers are sobering.

What Retirees Can Actually Do About It

Here’s where I pivot from the problem to the solution, because that’s why Margaret called me — and probably why you’re reading this. There are concrete, actionable steps that can help you retain more of your Social Security income in 2026 and beyond.

Manage Your MAGI to Avoid IRMAA Surcharges

One of the most overlooked strategies I use with clients is Modified Adjusted Gross Income (MAGI) management. IRMAA surcharges are based on your tax return from two years prior — so your 2024 return determines your 2026 Medicare premiums. If your income crossed one of the IRMAA thresholds due to a one-time event like a Roth conversion, a capital gains distribution, or the sale of property, you may be able to file a Social Security Life-Changing Event form (SSA-44) to request a reduction.

Even if you don’t qualify for the life-changing event exception, proactive tax planning for future years — like spreading Roth conversions over multiple tax years or timing capital gains — can keep you below the next IRMAA tier and save hundreds or even thousands annually.

Audit Your Medicare Coverage During Open Enrollment

Every year from October 15 through December 7, you have the opportunity to change your Medicare coverage. I cannot stress this enough: do not auto-renew without reviewing your options. Use the Medicare Plan Finder tool to compare plans in your area based on your actual prescriptions and preferred doctors.

In 2025 alone, I helped three clients switch from Medicare Advantage plans that had quietly reduced benefits to either different Advantage plans or Original Medicare with a Medigap supplement — and in each case, the net savings exceeded $1,200 per year.

Reassess Your Withdrawal Strategy

If you’re drawing from retirement accounts alongside Social Security, the order in which you withdraw matters enormously. Pulling too much from a traditional IRA or 401(k) can push your income into a higher IRMAA bracket, increase the taxable portion of your Social Security benefits, and even trigger higher state income tax obligations.

A blended approach — drawing from taxable, tax-deferred, and tax-free (Roth) accounts in strategic proportions — can minimize your total tax burden and keep more money in your pocket. This is one area where working with a CPA or Enrolled Agent who specializes in retirement tax planning pays for itself many times over.

The Social Security Trust Fund Question Everyone’s Asking

I’d be remiss if I didn’t address the elephant in the room. The Social Security Board of Trustees has projected that the Old-Age and Survivors Insurance (OASI) Trust Fund could be depleted by approximately 2033-2035, at which point incoming payroll taxes would cover only about 79-83% of scheduled benefits.

Does this mean your benefits will be cut by 20% in 2033? Not necessarily. Congress has historically acted to shore up the program — though usually at the last possible moment. What it does mean is that planning as if your full benefit is guaranteed forever is risky. Building even a modest buffer through personal savings, strategic investment in low-risk instruments like Treasury I-Bonds or short-term bond funds, and reducing fixed expenses can give you crucial flexibility.

Margaret’s New Plan — and What You Can Learn From It

After our initial phone call, Margaret and I spent two sessions going through her full financial picture. Here’s what we changed:

• Switched her Medigap plan from Plan F (which she’d held since 2019) to Plan G with a different insurer — same hospital and doctor coverage, $1,440 less per year in premiums
• Filed an SSA-44 because her 2024 income was artificially inflated by a one-time pension lump-sum payout, which had triggered an IRMAA surcharge she didn’t owe
• Adjusted her IRA withdrawals to stay below the first IRMAA threshold in 2026, supplementing with draws from a small Roth IRA she’d funded in her 60s
• Applied for her state’s Property Tax Freeze program for seniors over 65, which she didn’t know existed — saving her $840 annually

The net result? Margaret’s take-home income after all premiums and taxes actually increased by about $2,900 for 2026, despite the fact that her Social Security COLA only gave her $660 on paper. That’s the difference between passively accepting a cost-of-living adjustment and actively managing your retirement finances.

The Bottom Line for 2026

The 2.8% Social Security COLA is real, and it’s welcome. But if you stop at the headline and assume it means you’re 2.8% better off, you’re almost certainly wrong. Rising Medicare premiums, IRMAA surcharges, supplemental insurance costs, and everyday inflation are all working against that increase.

The retirees who come out ahead are the ones who treat their finances like Margaret ultimately did — not as a static situation, but as something that requires annual review and adjustment. You don’t need to become a tax expert. But you do need to ask the right questions, use the free tools available at SSA.gov and Medicare.gov, and consider working with a professional who understands the intersection of Social Security, Medicare, and tax law.

In my experience, the single most expensive mistake retirees make isn’t a bad investment — it’s inaction. The system rewards people who engage with it. Be one of those people.
